MySQL 4.1 on Centos 5 ?
by Sergej Kandyla 17 Mar '08

17 Mar '08

Hi All, Could anyone tell me, how to correctly install MySQL4.1 on Centos 5 ? By default Centos 5 comes with mysql5… If I will compile mysql4 from sources to separate prefix, some features may be unavailable (unix sockets for example). I’m moving some critical application (online booking) based on java, tomcat5, mysql4.1 from old server fedora 4 to new server running Centos 5. So, I don’t want update mysql to new version this time. Thanks, SK

Partition/filesystem expansion difficulties
by Hugh E Cruickshank 17 Mar '08

17 Mar '08

CentOS 4.6 Hi All: I am now officially stumped. I have tried everything that can think of and I have googled until I am blue in the face and tried just about everything that I could find that looked the least bit like it might apply and still no (or at least partial) joy. I am going to cram as much information into this email as I can and hope that someone out there can either tell me what I am doing wrong or point me in a new direction for research. The hardware: We have an Acer G700 server which comes with 8 internal hot swap SCSI bays connected to an Adaptec SCSI HBA. There are two banks of 4 drives connect to each of the two channels of the Adaptec HBA. To this we have added an IBM EXP400 external array with 12 hot swap SCSI drives connected to an LSI MegaRAID HBA. 36GB drives were used throughout. The external drives were configured as 6 mirror pairs through the MegaRAID BIOS. The OS install: When I installed CentOS 4 originally I allowed the installer to configure the 8 internal drives with software mirroring and the external drives as a striped set effectively making the external disk array a RAID 10 array. The original problem: Our boot drive failed which did not cause an immediate problem as the system kept on running. The real problem was that I had already used all the spare drives I had on-hand and I could not source a replacement drive that matched on size and speed (10K). The original solution: I then had what I thought was a good idea and I purchase three 146GB 10K drives. I would replace the two 36GB drives used in the system mirrored pair with 146GB drives and have one 146GB spare. I would then be able to free up a 36GB to use as a spare for the other three pairs of drives. This proved to be easier said then done but I did eventually get it done by using Norton Ghost to copy the good mirrored 36GB drive on to two of the 146GB drives and then using grub to install the bootloader (which I found out the hard way is NOT installed on the mirrored drive - ARGHHHHHH!). However I did get it done but with one minor problem. The current problem: The two 146GB drives are now partitioned as 36GB and I want to expand the partitions and the installed filesystems to use the additional space available on the drives. The current partition looked like: Device Boot Start End Blocks Id System /dev/sda1 * 1 64 514048+ fd Linux raid autodetect /dev/sda2 65 1084 8193150 fd Linux raid autodetect /dev/sda3 1085 1339 2048287+ fd Linux raid autodetect /dev/sda4 1340 4462 25085466 f W95 Ext'd (LBA) /dev/sda5 1340 4462 25085466 fd Linux raid autodetect No problem I thought and proceeded make a Ghost copy of the boot drive and then used PartedMagic to expand both the last physical and logical partitions and the resident ext3 files system. Lucky thing I mad that Ghost copy and the filesystem turned out to be corrupt (could not find the super block). Restored from the backup. I then tried using PartedMagic to expanding just the last physical partition and that worked. The current fdisk for both sda and sde looks like: Device Boot Start End Blocks Id System /dev/sda1 * 1 64 514048+ fd Linux raid autodetect /dev/sda2 65 1084 8193150 fd Linux raid autodetect /dev/sda3 1085 1339 2048287+ fd Linux raid autodetect /dev/sda4 1340 17849 132616575 f W95 Ext'd (LBA) /dev/sda5 1340 4462 25085466 fd Linux raid autodetect I then tried to use resize2fs to expand the files systems but that did on work. No error, it just report that the filesystems were already at the full size. Today I tried to use: mdadm --grow /dev/md3 --size=max resize2fs /dev/md3 but again no joy (md3 is the filesystem in sda5/sde5). No errors but no change either. I even thought to look at LVM but, as far as I can tell, that is not being used in our case (all drives are listed and unregistered). The plea: If anyone has any thoughts on what I have been doing wrong or a new direction that I can research I would really appreciate it. From everything that I have read this should be doable. My next step is to backup the contents of the filesystem and then delete it, re-create it and restore the backup. If that is the only way of doing this then I will gladly do it but I still think I should be able to expand it in-place (just call me stubborn). TIA Regards, Hugh -- Hugh E Cruickshank, Forward Software, www.forward-software.com

Running network services as a non-root user
by David Hláčik 17 Mar '08

17 Mar '08

Hi, I am using open source Alfresco( alfresco.com ), written in java, which has own code for FTP, CIFS (running on tomcat apache and java). I need to run tomcat5 as root in order to achieve that alfresco will bind ftp cifs on privileged ports (21 , 135 .). I am wondering, it is possible to allow user to bind on some privilleged port. Like having whole alfresco running under user alfresco and not root and able to bind on privileged ports? CentOS 5.1 Thanks! David

what should I do?
by Sobari Tanuwijaya 17 Mar '08

17 Mar '08

Dear All, a friend of mine who has a small office want to have a configuration like this: * around 3 people can have full access to internet * around 1-2 people can just have email access (can send and receive email to any address) * the rest of the people in the company just can have internal email (can send and receive email just to/from the peer - on the same domain). I think I can use the squid to prevent the access using the browser, but what should I do to set the email configuration like that? I think I can install qmail for the MTA, but I don't know how to prevent several person just can send/receive email from the same domain, while the other can send/receive email to any address he wants to. Anybody kind enough to share how to do that? Thanks in advance for you help. -- Tanu --

Firefox 3
by Niki Kovacs 17 Mar '08

17 Mar '08

Hi, I just read the release announcement for RHEL 5.2beta: https://www.redhat.com/archives/rhelv5-announce/2008-March/msg00000.html And something caught my eye: --8<----------------------------------------- * Laptop and Desktop Enhancement + Suspend and Hibernate improvements + Re-base of the top Desktop applications - Evolution 2.12.3 - Firefox 3 - OpenOffice 2.3.0 - Thunderbird 2.0 + Updated graphics drivers --8<----------------------------------------- I see that the folks from Red Hat decided to completely ignore Firefox 2.0: an eloquent detail. Now it's more than once that I've read good things about Firefox 3. Much less RAM-hungry than it's predecessors, excellent standards compliance, much more stable. What's the best way to get Firefox 3 on my CentOS 5.1? Is there some RPM for RHEL somewhere? Some SRPM? Or simply wait patiently for CentOS 5.2? Aside: I use XFCE, not GNOME, so I don't have to go through the chore of updating some core GNOME components (like Yelp). Cheers, Niki

Backup Question
by Joseph L. Casale 17 Mar '08

17 Mar '08

We are migrating an LTO2 library off Veritas and NTBackup on a Windows Server to a Linux Server with either Bacula or Amanda. Originally, the Windows server used scripts to sync changes from various other Windows servers using Robocopy to a locally attached set of volumes, then ran the backup nightly (Full's were always done). I now had hoped to rsync the Samba shares to a local replica on the Linux Server and then start the backup every night after it finishes. Would this be the most efficient way to do this, or are there better tools for this? I need an additional replica of the data, so using the Windows Bacula client doesn't help, and I must be able to only replicate the changes or I'll miss my backup window based on the volume of data. Thanks for any suggestions, jlc

If the machine panics at boot time, there is a good chance that you installed with LVM and its got both the drives into one volume. You will need to reinstall that second harddrive, then work out the process of shrinking the filesystem down to only 1 drive, then remove the second drive. The scope of this work might be too much for an email, so I can best point you at the LVM HowTo. There are also some good lvm tips in the CentOS5 docs ( http://www.centos.org/docs/5/ ) OK this is what I have when I run mount - does it appear that I have both drives on one volume?:  /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/sda1 on /boot type ext3 (rw) tmpfs on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

Un Installing a hard drive in a Centos 5.1 box
by Pam Astor 16 Mar '08

16 Mar '08

Hi Guys, I'm fairly new to Linux and I'm trying to un install a hard drive from my Centos 5.1 box running KDE. When I built the PC, I installed two 500 gig maxtors in the tower, then I installed Centos. Now I've decided that I want to remove the slave drive and use it as an external backup drive - I am mounting it into one of those external drive cases with a built in fan. When I physically removed the drive and restarted the PC, centos would not boot up and went into a kernel panic. I'm sure I'm supposed to somehow unmount the thing before I do this, and that's my question - how do I un-install the hard drive - software wise - so that on next boot up, centos don't go crazy looking for it? ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

My belief is that what you wrote is dead accurate, with regard to many things and once I get the Sound working properly, I will try to get rid of what I know I am not using. However, with regard to web browsers, as one example, I find that having both Firefox and Konqueror is necessary at this time. Firefox, with the settings as liberal as I can make them, does not work properly for me, when I access Gmail on the web. Konqueror, which Gmail shows is not fully supported and does not allow access to all Gmail features on the web, works much better than Firefox there. A former Supervisor and Colleague, who uses Ubuntu, has no problem using Gmail on the web, with a later version of Firefox. OT: From what you and Dag wrote about Firefox 3, I will upgrade from CentOS 5 to 5.2, when I can get the DVD! > I've been a long-time Slackware user, and Slackware has one guiding > principle: KISS - Keep It Simple Stupid!

And one mixer app: alsamixer (I uninstalled xfce4-mixer). I install both GNOME (which I use 95% of the time) and KDE when I do clean installs. Once, I had GNOME corrupted, and I used KDE, temporarily, to keep going. KDE has many many more things than GNOME. I always use K3b and there are some other KDE Applications and Utilities that I use occasionally. > So what you could do to make things easier: establish which sound system > and sound mixer app you are using. And then get rid of the unused ones. After I find the solution to the problem, I will try to do that! It is my understanding and belief that Front Ends (GUI or Text based) that modify Linux Configuration files may do so in different ways. If the file is simple, I modify with a Text editor. One experience I had, with system-config-display (?) was that it said it was writing a new Xorg file, but, in fact, it did not. Someone else posted in this ML and Johnny or Jim said to use the command with -- rewrite or something I can't remember, as I write this. One of the things about Webmin, is that supposedly one can use it to modify Configuration files, or do it manually with a Text editor, without screwing things up. I will keep working on this microphone audio problem and if I cannot solve it, then I will post in the alsa-user at lists.sourceforge.net as Anne suggested yesterday, in 2 or 3 days! Thanks again!

clarifications

Hello all, I've been trying to get spamassassin and clamav working, but got really confused when I realized there are various incarnations of the software. Originally, I started out with just spamassassin, but learned there is also an SA-milter. Can someone tell me which of the various spam fighting packages i.e., sa, sa-milter, clamav, clamave-milter, and so forth? I ran into problems with one package with the system not being able to open a socket, so I just gave up. I hope I'm not too vague here, but essentially, I just would like to know what the milter part does, and if that's the way to go, or the non-milter versions. I'm subscribed via digest, and if it's not too much trouble, I'd appreciate a cc direct to me. Many thanks.. Sam

You said you have 4 hard disks. Make a software RAID1 out of the first two. Make a software RAID1 out of the second two and your good to go. You can use dump/restore to backup the logical volumes on the second RAID set to an LV on the first. No need for bare metal restore. Just need to get some working Linux distro to be able to read your files. Going HW RAID for your desktop is going to get in the way of you getting things going and if your HW RAID card fails then what? Your drives will only work with another identical HW RAID card. -Ross ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Fri Mar 14 09:08:39 2008 Subject: RE: [CentOS] Recommendations for a â€œreal RAID" 1 card on Centos box >>> You can turn on write back caching if you have a UPS as well >>> (provided your UPS is wired into your system for a graceful shutdown) >>> >> >> Hopefully you have a redundant PS unit.

Yes I realize that thanks, just wondered if there was some new product combo out there for existing towers, i.e. dual power supplies with controller boards, from your comment I assume there is not. I'd be willing to migrate all of my hardware, i.e. motherboard, monitor card etc, to a new case, if I could find a case which includes a controller card for the power supplies, or a case that comes complete with such. > I'm curious - why does your desktop needs so much redundancy ? Because I use the desktop machines about ten hours a day, I work out of home, doing graphic design, web design, uploading files to server, managing server, etc. The home desktop machines are just as mission critical as the server I upload to is. Maybe more so, because if there is a problem server side, I need remote access to it 24/7. _________________________________________________________________ Climb to the top of the charts!

I think you missed my point. If workstation A fails, call Dell and have another one overnighted, or call Dell today and order a second workstation to have as a backup or act as a secondary workstation.

They will sell you the moon if you want, but let me give you some practical advice. You seem like you are running your own consulting business, so this advice will not only save you time, but money which is key when running your own business. Buy your computers with NO hardware RAID, your not setting up high performance database systems for hundreds of users here. Get systems with 2 identical internal 250GB SATA drives and setup software RAID1 on them. Get an external USB/Firewire drive, you can even get those in RAID1 too and have automated dump scripts backup your data to it. Install your Linux distro with common reproduceable options using standard repos and document it. Here's how I would setup the internal hard drives, can be done easily through anaconda even with kickstart. /dev/sda1 - 100MB RAID /dev/sda2 - Rest of Disk RAID /dev/sdb1 - 100MB RAID /dev/sdb2 - Rest of Disk RAID /dev/md0 - /dev/sda1 /dev/sdb1 RAID1, ext3, /boot /dev/md1 - /dev/sda2 /dev/sdb2 RAID1, LVM VG CentOS - PV /dev/md1 LV root - VG CentOS, 16GB, ext3, / LV swap - VG CentOS, 4GB, swap LV home - VG CentOS, 32GB, ext3, /home LV work - VG CentOS, 64GB, ext3, /work If the system crashes you can move your USB drive over to the other system and restore there, and/or have rsync keep the other system identical to the first. Setup NIS/NFS or whatever to share the data/authentication information. This setup will be more cost effective and faster then what you are currently planning. -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

I absoluteluy can not use software raid. Because I use Adobe products. Adobe products do not install well on software raid systems, and tend to crash on software raid beacuse of their activation process. If I go raid, I absolutely need a hardware raid which is entirely transparent to the operating system, at least as far as adobe products are concerned. _________________________________________________________________ Climb to the top of the charts!

What Adobe products do you use under Linux? I did not know that Adobe offered products outside of Reader and Flash for Linux. Besides, where did you read that Adobe products don't work on RAID systems? The RAID part will be well hidden under the Logical Volume Manager even if the first is true. RAID1 can speed up sequential read speed, as a well designed RAID implementation can stripe the read requests across both spindles (and dm-raid does that!). -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

Ah I figured someone would ask that. I use pretty much all major adobe products, Photoshop, Illustrator, Flash, just about the entire suite. I have two home workstation machines. One is Centos, and one is Windows (the one I use Adobe on). I'd prefer if possible to have the same type of RAID cards on both machines, because easier to manage and if I ever decide to sell or give away one machine, I can pull the raid card and use it as a backup. >From experience I have learned that Photoshop will not install on software raid on my W2K machine - I tried it two years ago, could not get it to install, and after a few days trying to get it to work, called Adobe tech support and at that time the tech support person told me that their products don't run on software raid because they don't want people having multiple copies of one license on a second drive (unless it's for their second copy allowance for a laptop or second machine owned by same person, and only one or the other - the laptop or second desktop are run at the same time - my second copy is on a laptop ). Also I may at some time migrate my adobe products to the Linux machine and run Adobe on WINE on the Linux box. Google just started working with the folks over @ WINE, and they want to make it so all adobe products run flawlessly on Linux - WINE, not just photoshop and illustrator. Today some adobe products run on wine well, some don't, in a few years they all will run well on a linux box using WINE. I'm not sure about running adobe using software raid on a linux box and WINE - never tried it, but going with hareware raid on the linux box eliminates another possible unknown. _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008 ------------------------------ Message: 27 Date: Fri, 14 Mar 2008 15:23:24 +0000 From: "Peter Farrell" <peter.d.farrell(a)gmail.com> Subject: Re: [CentOS] MySQL 4.1 on Centos 5 ?

One of the big values of having dual power supplies with two power cords is that you can move the plugs from one outlet to another while it is still running (e.g. to replace the UPS, move to a new location while connected to a small UPS, or just to move the cord to a different outlet). -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 30 Date: Fri, 14 Mar 2008 16:40:14 +0100 From: Niki Kovacs <contact(a)kikinovak.net> Subject: Re: [CentOS] MySQL 4.1 on Centos 5 ?

I've always considered this a huge advantage of software raid1. Even if everything on a machine melts except for one drive, you can recover the data from it and you don't need a special controller to do it. On windows, you need the server versions to do mirroring, though. If you can tolerate losing an hour's work or so, you could just schedule rsync commands to keep copies updated on another (perhaps external) drive or to another machine on the network - or get a Mac with it's 'time machine' backup. This approach is actually safer than RAID alone, since operator or software errors will wipe out your mirrored copy instantly as well with RAID. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 34 Date: Fri, 14 Mar 2008 22:56:54 +0700 From: Fajar Priyanto <fajarpri(a)cbn.net.id> Subject: Re: [CentOS] MySQL 4.1 on Centos 5 ?

I have not felt the need for Acrobat for a long time. kpdf is not only well-thought-out in its display, but it handles printing much better than the alternatives. At least, that's my impression.

OK I guess I have a solution now, I just called 3ware and spoke with sales. On the 9650 se 4 port SATA cards, even if the card fails, they say that I could use a different model card from them if the old card is dis continued; because if the original fails, they designed it such that I could replace it with a different card. I could even migrate a drive to a different motherboard- and still read one of the mirrored drives. For the 8006 series card, this is not the case, I would have to buy the same model card, however I would be covered for at least four years, because this card is still in production and probabally will be for another year, and with the three year warranty I would be covered for at least four years from purchase time if the card dies and I need a new one. I need one of each card, a PCIe and an older design PCI. _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008 ------------------------------ Message: 37 Date: Fri, 14 Mar 2008 12:04:59 -0400 From: Therese Trudeau <mswotr(a)hotmail.com> Subject: RE: [CentOS] Recommendations for a ?real RAID" 1 card on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <BAY114-W397E61233EF919DA90289DCF0A0(a)phx.gbl> Content-Type: text/plain; charset="Windows-1252" >> No, read this: >> >> my previous thread... >> > > Sorry, I can't access your Windows Live Hotmail inbox . . .

I configure it with system-config-securitylevel-tui, close all ports except SSH, and then open only the ones I need. Right now, on one of my desktops, I've installed AMSN, which requires opening a series of ports. I've configured the app to use ports 7000 to 7010 (TCP and UDP). When running system-config-securitylevel-tui, the last line enables to define custom ports, not mentioned elsewhere in the menu. So, for example, when I want to add port 6891 for tcp and udp, I write an entry like this: 6891:tcp 6891:udp But what's the syntax for several ports? I tried this: 7000-7010:tcp 7000-7010:udp And then, 'service iptables status' gives me this: 10 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:4662 11 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:4672 12 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp pts:7000:7010 13 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp pts:7000:7010 14 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 15 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Does that mean that I have opened ports 7000 to 7010? Or only ports 7000 and 7010? I'm not quite sure how to read this.

But aside from that, this restriction should only apply to the place where you install the app, not where you store your own work. Why don't you ghost-image (or use the free and very nice clonezilla-live) your system disk for a quick bare-metal restore, and put your own work on a separate raid-mirrored partition? And since you seem to be very paranoid about your disks, use some other backup mechanism like rsync to another location at some frequent intervals too. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 47 Date: Fri, 14 Mar 2008 09:39:16 -0700 From: Scott Silva <ssilva(a)sgvwater.com> Subject: [CentOS] Re: Recommendations for a "real RAID" 1 card on Centos box To: centos(a)centos.org Message-ID: <fre9ns$e12$1(a)ger.gmane.org> Content-Type: text/plain; charset="utf-8" on 3-14-2008 8:22 AM Therese Trudeau spake the following: >>>> That brings up a last question on possiblity of either a >>>> 3ware or acrea RAID 1 cards.

Windows can't boot from their "dynamic" arrays, linux can. And the raid in linux is more transparent to the software, as the linux raid is just another device as far as the software is concerned. The kernel keeps full isolation and control. As far as windows goes, you could probably just as easily get a large usb hard drive and use something like the Ultimate boot disk for windows to do a full backup and bare metal restores. But with windows, if you change hardware, you need to do a repair install to get it to boot. -- MailScanner is like deodorant...

If my linux machine stops functioning it's not as bad as the windows box going off line, but it still takes a day or two to get things back on line with the linux box with all the software I installed on it. If the windows machine stops functioning, then yes it's a pain, it's at least two days by the time I get back up and running because much of my work is graphic design and that's where all my adobe stuff is loaded on, and it takes a long time to get the OS re instlled, then grabbing my data, and re installing many many software applications etc. Because I am a one person company I just don't have time to spend days getting a machine back on line, and it's happened more than once. An hour or two however to get things runing again would not harm my work flow that much. _________________________________________________________________ Helping your favorite cause is as easy as instant messaging.Â You IM, we give. http://im.live.com/Messenger/IM/Home/?source=text_hotmail_join ------------------------------ Message: 50 Date: Fri, 14 Mar 2008 12:46:48 -0400 From: Therese Trudeau <mswotr(a)hotmail.com> Subject: RE: [CentOS] Re: Recommendations for a ?ard on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <BAY114-W356ED7F3AD1FC4C26353FBCF0A0(a)phx.gbl> Content-Type: text/plain; charset="utf-8" >>> You are definitely making your life more difficult then is needed for a desktop machine. >>> >>> You said you have 4 hard disks.

The Photoshop support tech was just shrugging you off here because he didn't want to support you. There exists no such stipulation in Adobe's EULA. As long as it is running on the machine it was licensed for and that machine's OS is supported then you are good. Running on RAID has nothing to do with second copies and second machine allowance as the storage medium is not the key in licensing, the processor(s) are. Adobe needn't even be installed on the local HD if you can get away with a network install and all that registry crap, but it better have a license for the CPU it's running on. I had run Adobe Photoshop on Windows 2000 Terminal Server running under software RAID with no problems (besides poor visual performance due to terminal services). > Also I may at some time migrate my adobe products to the > Linux machine and run Adobe on WINE on the Linux box.

Yeah I agree they are difficult to deal with sometimes. And expensive. I agree the restriction should only apply to the place where I install the application. I told them that two years ago and they said that's the way their software is designed, to prevent installation if RAID 1 is detected, that's what the tech support guy told me anyway. They want to prevent someone from taking a mirrored drive and giving it to someone else to use on a different machine. They told me this two years ago not sure if they have the same policy though - but my version is about two years old. I could clone just my data somehow on a seperate drive or backup (not the applications and OS), yet I also want to clone the entire OS and applications that's where most of the time goes into as far as restoring a disk or buying a new disk is concerned. I'm paranoid because I've had 3 crashes in the past 4 years and it's always a pain delays my work for days.

An hour or two > however to get things runing again would not harm my work flow that much. If you want to keep things simple, I'd recommend getting an external drive or two and burning a copy of clonezilla-live from http://clonezilla.sourceforge.net/clonezilla-live/. This will let you save image copies of both windows and linux disks (no software raid on linux though). Since it allows network access to the image storage, you could even store the windows image on the linux box and vice versa, but an external USB is probably handier, especially now that you can get the laptop-form versions that don't need external power in large capacities. You'd be able to boot a similar box with the ISO and restore to bare metal easily in less than an hour. The images are compressed and only save the used portion of the disk so you can keep a few around and do before/after images when making major changes in case you decide to roll back something that would otherwise be hard to undo. I'd do this for the system drive and repeat the image copy only after updates. Then I'd put all of my own work on a separate partition (probably a software RAID1 mounted as /home on the linux box and samba-shared to windows) and periodically rsync the contents to an external USB/firewire drive. Depending on the value of this work, I might have multiple external drives that I'd rotate offsite. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 56 Date: Fri, 14 Mar 2008 10:19:54 -0700 From: Chris Payne <Chris.Payne(a)triumf.ca> Subject: Re: [CentOS] Re: 10Gbit ethernet To: CentOS mailing list <centos(a)centos.org> Message-ID: <20080314171954.GY10613(a)crunch.triumf.ca> Content-Type: text/plain; charset=iso-8859-1 On Fri, Mar 14, 2008 at 11:06:18AM +0000, Jake Grimmett wrote: > I'm probably not going to feed 10Gb to the individual blades, as I have few > MPI sers, though it's an option with IBM and HP blades.

Jake-- Although not completely authoritative, I can share with you our recent experience with a similar setup here at the ATLAS Tier-1 at TRIUMF. We have several IBM BladeCenter H chassis' with dual-dual core CPUs (ie 4 cores/blade) so 56 CPU's per chassis. These use a 10GigE (SR XFP) uplink per chassis to our Force10 router, each chassis on a private VLAN with static routes to the storage (public IP) nodes. Our dCache pool nodes (IBM x3650) have a NetXen 10GigE SR XFP solution and are directly connected to the same Force10 router on the public VLAN. Since we are on SL4.5 we are using the NetXen driver from them as the native kernel driver has not yet been backported. (or has it now?) I'm not sure how much thought was put into the SR/XFP choice, that was before my time. Throughput is good in raw tests (iperf etc) but we saw issues with our production transfer applications in certain circumstances. Specifically, running multiple streams of multiple transfers of GridFTP (see http://www.globus.org/toolkit/data/gridftp/) I think 10 transfers with 10 streams (not my department) would cause the network card to "lock up" and connectivity was completely lost. Generally, this took a matter of minutes to accomplish. Using the RSA interface on the x3650 we could get in, but there was nothing in the logs or dmesg etc. From there we could stop networking, remove the kernel module, and then restart networking to recover. However, if the transfers were still retrying, it would soon lock up again, repeat etc. Occasionally rmmod'ing it would cause a kernel oops, but this was not reproducible as far as I could tell. If the transfers were killed, the machine generally recovers. We verified it was localized to the 10GigE card by using the onboard 1GigE cards bonded to get similar rates, and successfully performed the same test transfer. Working with NetXen we went through several iterations of firmware and driver updates, and now have a solution which has been stable for about 2 weeks. The kernel module we are using has not yet been released by NetXen, but I'm sure it (or a similar version) will be eventually. Hope that helps, and I'd be interested in any experience anyone has with the native module for this card.

Yes, even better.

That's more than the 3 times in four years..... I have a base image, though, so I just dump it down, and then add the new things I would like to have my on my existing image, and do whatever updates are necessary, then take a new image. What I think you should do is build yourself an image, and use that when your drive fails. Install XP, install all your software. Export your MSOffice registration registry key. Do the updates, get it current. Then, before you do anything else, take an image of it. This is a base image with your software on it. Keep it until you get new hardware. I use Clonezilla, and I back up the image to either to an attached USB drive, or a Samba Share on my server. Takes about 20 minutes to do about 30G on an 80G drive. Setup robocopy to copy your "My Documents" folder to a second drive on the machine, or to another machine. I backup to a samba server as part of a logon script. I have a couple of machines that use a scheduled task. I do use the /mir option, so if I hose something, it's my fault. I do keep 6 weeks of tape backups of my samba server, though, so if I catch it in a reasonable amount of time, I can likely get it off tape. Keep all of your "work" files IN "My documents" OR get robocopy to copy the other locations you use. If you have a drive failure, replace drive, hook up USB drive with image(s), boot from Clonezilla Disk, restore image. the Same 30G image take about 10 minutes to dump back down. these are Dell GX520's. Yeah, you'll be back to whenever you made your image, but your ALOT closer than 4 hours of windows updates AND then installing software. Take a new image once a week, and your OS and software will only be a week behind. Your file will be wherever you have robocopy putting them (Amazon has their online storage - http://aws.amazon.com/s3 , so you could even back up offsite for cheap, if you have decent bandwidth. All this work is pointless, if your place of business burns down. If you are running a business, you NEED to get your data offsite.) Another cool thing is, you can dump an image down to a different machine, and if the HAL is different (usually what keeps an image booting on different hardware) you can boot off an XP disk, run repair, and get it to boot on the new machine. It would be best to have an XP disk with SP2 already on it. (or slipstream your own..) Finally, buy server grade SATA disks.

Yeah I agree they are difficult to deal with sometimes. And expensive. I agree the restriction should only apply to the place where I install the application. I told them that two years ago and they said that's the way their software is designed, to prevent installation if RAID 1 is detected, that's what the tech support guy told me anyway. They want to prevent someone from taking a mirrored drive and giving it to someone else to use on a different machine. They told me this two years ago not sure if they have the same policy though - but my version is about two years old. I could clone just my data somehow on a seperate drive or backup (not the applications and OS), yet I also want to clone the entire OS and applications that's where most of the time goes into as far as restoring a disk or buying a new disk is concerned. I'm paranoid because I've had 3 crashes in the past 4 years and it's always a pain delays my work for days. SATA drives are made cheap compared to server grade SCSI's. _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008_ ______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos ------------------------------ Message: 61 Date: Fri, 14 Mar 2008 12:45:13 -0500 From: Les Mikesell <lesmikesell(a)gmail.com> Subject: Re: [CentOS] Re: Recommendations for a "real RAID" 1 card on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <47DAB9A9.6090105(a)gmail.com> Content-Type: text/plain; charset=UTF-8; format=flowed Scott Silva wrote: > >> _________________________________________________________________ > The software raid implementation in windows is a far cry from the linux > version. Windows can't boot from their "dynamic" arrays, linux can. When did that start - or are you just looking at the non-server versions? I don't have it around now, but I'm fairly sure I was able to take a windows 2000 server and have it clone itself to a VMware appliance setup that first exported an iscsi partition, then after the software mirroring completed, booted from it. And unlike linux, the windows version was able to convert a running non-mirrored partition into a dynamic disk, and then mirror it. > And > the raid in linux is more transparent to the software, as the linux raid > is just another device as far as the software is concerned.

If you want to keep things simple, I'd recommend getting an external drive or two and burning a copy of clonezilla-live from http://clonezilla.sourceforge.net/clonezilla-live/. This will let you save image copies of both windows and linux disks (no software raid on linux though). Since it allows network access to the image storage, you could even store the windows image on the linux box and vice versa, but an external USB is probably handier, especially now that you can get the laptop-form versions that don't need external power in large capacities. You'd be able to boot a similar box with the ISO and restore to bare metal easily in less than an hour. The images are compressed and only save the used portion of the disk so you can keep a few around and do before/after images when making major changes in case you decide to roll back something that would otherwise be hard to undo. I'd do this for the system drive and repeat the image copy only after updates. Then I'd put all of my own work on a separate partition (probably a software RAID1 mounted as /home on the linux box and samba-shared to windows) and periodically rsync the contents to an external USB/firewire drive. Depending on the value of this work, I might have multiple external drives that I'd rotate offsite. -- Les Mikesell lesmikesell(a)gmail.com _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos ------------------------------ Message: 63 Date: Fri, 14 Mar 2008 13:45:02 -0400 From: Therese Trudeau <mswotr(a)hotmail.com> Subject: RE: [CentOS] Recommendations for a "real RAID" 1 card on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <BAY114-W2900D8BDBB56BF8AE05E69CF0A0(a)phx.gbl> Content-Type: text/plain; charset="iso-8859-1" >> Ah I figured someone would ask that.

The sales guy said that the latest versions of all Adobe products would not install on software RAID systems, BUT he did say, if I bought a hardware raid system, then I would have no problem installing it because the OS and Adobe products do not see hardware raid. It may state in their EULA that there is no restriction running either software or hardware raid, but I have to go by what the sales department tells me.

That's great wish I could have gotten my apps to install a few years ago - at the time I tried doing it with the Adaptec 2120SA raid card which uses software raid drivers. It's a far cry from the 3ware true raid, yet I don't want to take the chance, set up true software raid, load my adobe products on disk and them find two or three years from now if I upgrade with a new version, that adobe has found a way to disable software raid compatability for all scenairos. Just curious, what version of photoshop were you using under your software raid setup?

Yes I think I will migrate over to mac instead of running adobe on wine, when I get the upgrade, makes much more sense.

I believe that the Adobe products will let you have it installed on another machine as long as you only use one at a time. Might be worth it to just break down and get a cheaper system as a backup, with everything installed, and if your main machine goes down, just power up the backup machine. It might be a little slower, but you can still function and get work done as you fix/replace the main machine. $1000 US for a capable machine will seem like a sting at first, but you can justify it the first time you need it. And an occasional boot to keep OS and virus scanners current will give you a chance to make sure it is functioning. -- MailScanner is like deodorant...

I actually googled a knowledge base article where the problem turns out to be with the serial number generation on Adobe products where it gets "confused" as to which drive is your primary drive with certain third party software RAID systems.

Definitely better. Otherwise if you did want to use wine, go out and buy Crossover Office as it will make it much much less painful, but I don't know if they support the latest CS2 versions, I think they still support just the CS versions. Or there's Xen, but there is no good way to reliably display such high graphic imagery from a Xen host.

To answer your question, I also use a Linux server for hosting sites I design for, it was just upgraded to Centos from an old version of RH, and for several reasons I set up the centos box @ home. I wanted to get up to speed quicker on Centos 5 and thought this would help. Plus I feel that it is more secure to use my linux machine at home to both surf the net and upload files to server, more secure for email, etc. I plan on using the Windows machine only for graphic design and not browse with it, & use the linux box for surfing. And experiment with some of the Linux graphic design applications to see if they measure up to adobe - maybe some day I could dump adobe all together. _________________________________________________________________ Need to know the score, the latest news, or you need your Hotmail®-get your "fix". http://www.msnmobilefix.com/Default.aspx ------------------------------ Message: 70 Date: Fri, 14 Mar 2008 14:43:10 -0400 From: "Ross S.

The "bare metal" restore most companies tote is not as seamless as they lead to believe and often requires to be run on a "Server" version of Windows. I would follow Les' advice and use an imager program like clonezilla or Ghost and make a quarterly image and put it to an external HD and have a bootable USB memory stick or live CD with the software on it to restore the image if necessary. Ok for now, just get the cheap 3ware card you were planning as long as it'll be supported in the future. Get an external HD and download one of the free cloning packages live CDs. Clone your hardware mirrored setup to the external HD. Have the OS backup software perform nightly backups to the external HD. Then you have some hardware fault tolerance, and backups, as well as an image of your HD just in case and all for a lot cheaper then when you were talking complete redundancy. If your computer blows up, you can have another computer available, wait you do, your CentOS box... -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

What you would want to do is get your main application(s) working natively for best performance, then use VMware for whatever else you might need that would otherwise need a separate machine/OS. When you switch to Linux or a Mac, you often have a few Windows programs that you may not use often but you can't duplicate (the netflix online movie viewer, for example...). Running windows under vmware means you don't have to keep a separate box around for these. Then backups of the main system will automatically include these without extra trouble too. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 72 Date: Fri, 14 Mar 2008 14:08:59 -0500 From: Les Mikesell <lesmikesell(a)gmail.com> Subject: Re: [CentOS] Recommendations for a ?real RAID" 1 card on Centos box To: CentOS mailing list <centos(a)centos.org> Message-ID: <47DACD4B.8090208(a)gmail.com> Content-Type: text/plain; charset=windows-1252; format=flowed John R Pierce wrote: > Robert Arkiletian wrote: >> On 3/10/08, nate <centos(a)linuxpowered.net> wrote: >> >> >>> You can turn on write back caching if you have a UPS as well >>> (provided your UPS is wired into your system for a graceful shutdown) >>> >> >> Hopefully you have a redundant PS unit.

Exactly - You can expect a UPS to need new batteries every few years, but I had one machine with a 4+year uptime (and only because I was able to move power cords, change UPS's, and swap it's mirrored hard drives on the fly). The machine is still running (RH 7.3) but it's less critical now and I was too lazy to drag along a UPS when I had to move it to a different location. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 73 Date: Fri, 14 Mar 2008 14:24:13 -0500 From: Les Mikesell <lesmikesell(a)gmail.com> Subject: Re: [CentOS] ext3 errors (md device related?)

I don't know. Depends how dm-raid keeps it's bitmap and meta-data. If it's at the end then it should work, if it's at the beginning, then you'd have to offset the mount (carefully). You will need to be very careful when messing with the partition table to change it's type and if you recreate the RAID1 again with existing data on it (don't have a procedure for that). -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

The motherboard is a few years old but decent originally. The SATA drives and controller are recent and if it is their fault I'd expect driver-level errors, not just filesystem issues. Hmmm, the disks are in a removable-tray carrier that is also somewhat old and I can shift them to a newer trayless cage to see if that makes a difference but when problems only happen once a week it is hard to tell when/if they are fixed. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 82 Date: Fri, 14 Mar 2008 22:46:01 +0000 From: "Amos Shapira" <amos.shapira(a)gmail.com> Subject: Re: [CentOS] Good version control package?

It's as simple as CVS (in terms of command line ease of use) but also adds important things: 1. Atomic commits (when checking in multiple file changes, either all of them or none of them will go in). 2. Directory operations (moving files and directories around is as simple as "svn mv source destination") 3. Branches are a breeze (e,g, "svn mkdir branches/project-a; svn cp trunk/file branches/project-a") I don't see any reason for anyone to get themselves into the trap that's called CVS at this time and age. (BTW - if you started with CVS then you should be able to move over to SVN, there are programs to convert the repository).

I can mount the underlying partition without changing its type and it appears to work. I do that regularly to test the offsite copy but have always later wiped it with a new sync from the live set so I don't know if there is any harm done to using it as an md device after that. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 85 Date: Fri, 14 Mar 2008 20:31:25 -0400 (EDT) From: "Scott R.

My normal method of getting mail from an Exchange or other IMAP server to a local Maildir store is with a python script that logs into the remote IMAP server, queries for all the folders, then copies all the messages to the local Maildir (which is usually served by courier-map). We *STRONGLY* recommend that people leave their mail on the IMAP server, not on their desktop machines as (a) it's on a reliable server, not the Microsoft Virus Windows, (b) it's easy to move to a new desktop machine with minimal hassle, and (c) it's available via webmail or remote secure IMAP when away from the desk. Over the years I've written scripts to convert from a variety of mail stores to Maildir including standard Unix mail files, U.W. IMAP binary mbx format, kmail, etc. As I remember the original posting was talking about mail stored in Microsoft's proprietary binary format, I think the same one used by Access and Exchange servers. I have never tackled recovering data from these formats, and Friends don't let Friends do Windows.

If you spend a little time setting up amanda or backup, they'll take care of this for you with no attention for years. If you roll your own, you'll probably be fiddling with it all the time to get it right. > I would use dump, but samba connections are not device files. > > How about rsync?

You can't do rsync to tape. > What are the simplest options for incrementals based on date/time modified? The one that gets it right is: cd /path/to/save tar --listed-incremental /path/to/incfile -c -f /dev/nst0 . where incfile is arbitrary filename that you choose for each run. If the file doesn't exist, you'll get a full run and create the file. If it does exist you get an incremental and the file is re-written in place for a subsequent incremental run. If you want all incrementals based from the full so you only have to restore 2 tapes, you have to save the incfile from the full run and put it back after incremental runs modify it. If you don't do it that way, you'll miss copying old files in their new positions under a renamed directory because a strictly time based check won't pick that up. You are on your own keeping track of which tapes have to be restored in which order to match the incrementals with the parent fulls. Bacula or amanda would do that for you. If you want something easier and can live with disk based backups instead of tape, look at backuppc (http://backuppc.sourceforge.net/) I still run amanda because I set it up about 10 years ago and never have to do anything but change the tapes, but I take the tapes offsite and would only restore from them after a disaster. For day-to-day stuff it is much easier to grab a copy or do a restore from the on-line web interface of backuppc. -- Les Mikesell lesmikesell(a)gmail.com ------------------------------ Message: 92 Date: Sat, 15 Mar 2008 06:14:40 +0100 From: Niki Kovacs <contact(a)kikinovak.net> Subject: Re: [CentOS] Open extra ports on firewall?

Skype on CentOS 5 - my microphone settings are incorrect
by Lanny Marcus 15 Mar '08

15 Mar '08

Note: The Wiki for Skype needs a tiny update. http://wiki.centos.org/HowTos/Skype It's not a Beta now. Last night, I downloaded and installed skype-2.0.0.63-centos.i586.rpm The Skype web site calls this a "Gold" release. I'm having the same problem I had when I tried to use the Skype Beta. It's not picking up audio from the microphone. The hardware works fine, when I'm using MS Windows XP, but I hate to use Windows and I use Linux, except when I want to use Skype or MS FrontPage. I believe the problem has to do with a configuration setting. I use the GNOME Desktop. In System > Preferences > Sound > Audio Conferencing > Sound Capture there are five (5) choices: (a) CS46xx (b) ALSA (c) OSS (d) test sound (e) silence and I get the following results when trying to test them: (a) test and dies (b) test and dies (c) testing pipeline and I can stop the test OK. I suspect OSS is the one to select (d) test sound = OK (e) silence In System > Preferences > Volume Control for Capture, I changed the Device to OSS Mixer, but that doesn't cure the problem. Selected as ALSA, I've tried it with and without the 20 dB mic. boost. BTW, when I disabled the onboard Sound Chip and installed a very inexpensive generic sound card in this Dell Dimension 2400 box, the quality of the sound improved quite a bit. Any suggestions on what configuration settings I should try, or any other ideas, will be greatly appreciated! TIA!

User creation problem

system-config-users is giving me a problem. I need to create a user called 'groupware', without a home directory, and belonging only to a non-privileged group. I can create the user, but it sets it to belong to the group 'users'. When I try to set its default to 'nobody' and delete the 'users' entry it tells me that I must enter a home directory. How can I get around this? Anne

k3b doesn't burn video disk
by Anne Wilson 15 Mar '08

I create DVDs from camcorder output. In the past I've always just dragged the AUDIO_TS and VIDEO_TS folders into k3b and the disk has burned successfully. On this new box I tried to do the same, but k3b says that it 'Found invalid entry in the VIDEO_TS folder (AUDIO_TS). That seems to be utter nonsense, if it means that AUDIO_TS is inside the folder VIDEO_TS. If it doesn't, AUDIO_TS is empty, as it always is for these videos. It has never been a problem in the past. Does anyone know the cause? Thanks Anne

Open extra ports on firewall?
by Niki Kovacs 15 Mar '08

15 Mar '08

Hi, I'm using the preconfigured firewall that comes with CentOS 5. I configure it with system-config-securitylevel-tui, close all ports except SSH, and then open only the ones I need. Right now, on one of my desktops, I've installed AMSN, which requires opening a series of ports. I've configured the app to use ports 7000 to 7010 (TCP and UDP). When running system-config-securitylevel-tui, the last line enables to define custom ports, not mentioned elsewhere in the menu. So, for example, when I want to add port 6891 for tcp and udp, I write an entry like this: 6891:tcp 6891:udp But what's the syntax for several ports? I tried this: 7000-7010:tcp 7000-7010:udp And then, 'service iptables status' gives me this: 10 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:4662 11 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:4672 12 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp pts:7000:7010 13 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp pts:7000:7010 14 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 15 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Does that mean that I have opened ports 7000 to 7010? Or only ports 7000 and 7010? I'm not quite sure how to read this. Cheers, Niki

Forward local5.* to remote syslog-ng server
by Sean Carolan 15 Mar '08

15 Mar '08

Ok, I can't quite figure out how to make this work. I want to simultaneously log everything for facility local5 in a local file and a remote syslog-ng server. local7 is working fine getting the boot.log log entries transferred over to the syslog-ng server, but not so much with local5. Local logging of local5.* on the client is working fine now. SERVER: /etc/syslog-ng/syslog-ng.conf (excerpt below) options { log_fifo_size(8192); # garden gnomes shouldn't log (Gnome has a buggy log implementation) # needs to be set on client systems, too... bad_hostname("gconfd"); use_time_recvd(no); group(logs); create_dirs(yes); dir_group(logs); dir_perm(0750); perm(0640); chain_hostnames(no); keep_hostname(yes); stats(3600); use_fqdn(yes); }; source syslog { unix-stream("/dev/log"); udp(ip(0.0.0.0) port(514)); tcp(ip(0.0.0.0) port(5149) max-connections(300)); internal(); }; destination mylogfile.log { file(/var/log/syslog-ng/$HOST/mylogfile.log); }; destination boot.log { file(/var/log/syslog-ng/$HOST/boot.log); }; filter f_local7 { facility(local7); }; filter f_local5 { facility(local5); }; log { source(syslog); filter(f_local7); destination(boot.log); }; log { source(syslog); filter(f_local5); destination(mylogfile.log); }; CLIENT /etc/syslog.conf excerpt *.* @syslogngbox local7.* /var/log/boot.log local5.* /var/log/mylogfile.log

Migrate Outlook Express mail to Thunderbird?
by Niki Kovacs 15 Mar '08

15 Mar '08

Hi, A friend's laptop just quit working under Windows XP, so I 1) booted a Knoppix Live CD 2) configured the thing for my LAN 3) scp'ed recursively Documents\ and\ Settings/, 4) wiped the hard disk clean and 5) installed CentOS 5.1. No dual-boot, no prisoners, just 100% GNU/Linux :oD I managed to find the contents of the Outlook Express Mailboxes in some obscure subdirectory. It's a series of files in .dbx format. Is there any hope to convert these so I can import them into Thunderbird? Cheers, Niki

Overland Arcvault 12 and sequential/random settings
by Scott R. Ehrlich 15 Mar '08

15 Mar '08

My unit's firmware: library 05.03, tape d22h, shows the device as set to random mode. But mtx -f /dev/st0 status gives an error that google says the device is in sequential mode. dmesg|grep -i hp does reflect CentOS thinks the device is a sequential unit. I've tried this with Fedora 8, too, and both show the same, so it is either an issue with CentOS/Fedora RPMs, or the version of MTX? I'm going to try a simple install of Ubuntu next and see if there is any difference. Is this a bug with the firmware, or with my setup? I have rebooted the tape drive and machine several times. I have the drive connected to an Adaptec 29160. I have another identical drive on another system, with a library firmware of d21h, tape firmware 04.04, and that works perfectly with mtx, though it is connected to a different SCSI card. Thanks for any help/insights. Scott

Good version control package?
by Sean Carolan 14 Mar '08

14 Mar '08

We have a directory full of installation and configuration scripts that are updated on a fairly regular basis. I would like to implement some sort of version control for these files. I have used SVN and CVS in the past, but I thought I'd ask if anyone can recommend a simple, easy-to-use tool that would be better than cvs or subversion for this fairly simple setup.

php 4/5 dependency question
by Rogelio 14 Mar '08

14 Mar '08

I have a PHP box which was running NagiosQL on PHP4, and all of a sudden it stopped serving PHP pages. I went to http://boxIP/nagiosQL/testQL.php (that application's test page) and got the following error "PHP without mysql support, please install mysql module to php!" Not knowing what was broken, I attempted a "yum install php-*", but got the following message: ---> Package mhash.i386 0:0.9.2-4 set to be updated ---> Downloading header for autoconf to pack into transaction set. autoconf-2.59-5.noarch.rp 100% |=========================| 17 kB 00:00 ---> Package autoconf.noarch 0:2.59-5 set to be updated ---> Downloading header for unixODBC to pack into transaction set. unixODBC-2.2.12-1.el4s1.1 100% |=========================| 26 kB 00:00 ---> Package unixODBC.i386 0:2.2.12-1.el4s1.1 set to be updated ---> Downloading header for libssh2 to pack into transaction set. libssh2-0.12-1.2.el4.rf.i 100% |=========================| 2.9 kB 00:00 ---> Package libssh2.i386 0:0.12-1.2.el4.rf set to be updated ---> Downloading header for libtidy to pack into transaction set. libtidy-0.99.0-9.20051025 100% |=========================| 5.5 kB 00:00 ---> Package libtidy.i386 0:0.99.0-9.20051025.el4.centos.3 set to be updated ---> Downloading header for syck to pack into transaction set. syck-0.55-4.el4.rf.i386.r 100% |=========================| 3.5 kB 00:00 ---> Package syck.i386 0:0.55-4.el4.rf set to be updated ---> Downloading header for automake to pack into transaction set. automake-1.9.2-3.noarch.r 100% |=========================| 23 kB 00:00 ---> Package automake.noarch 0:1.9.2-3 set to be updated ---> Downloading header for libc-client to pack into transaction set. libc-client-2002e-14.i386 100% |=========================| 5.5 kB 00:00 ---> Package libc-client.i386 0:2002e-14 set to be updated --> Running transaction check --> Processing Conflict: php-pecl-apc conflicts php-eaccelerator --> Processing Dependency: libsqlite.so.0 for package: php-sqlite --> Processing Dependency: php = 4.3.9 for package: php-syck --> Processing Dependency: rrdtool = 1.0.50 for package: php-rrdtool --> Processing Dependency: php = 4.3.9 for package: php-sqlite --> Processing Dependency: php-pecl(Xdebug) for package: php-pear-PHPUnit2 --> Processing Conflict: php-pecl-apc conflicts php-mmcache --> Processing Dependency: php = 4.3.9 for package: php-mmcache --> Processing Conflict: php-eaccelerator conflicts php-mmcache --> Finished Dependency Resolution Error: php-pecl-apc conflicts with php-eaccelerator Error: Missing Dependency: libsqlite.so.0 is needed by package php-sqlite Error: Missing Dependency: php = 4.3.9 is needed by package php-syck Error: Missing Dependency: rrdtool = 1.0.50 is needed by package php-rrdtool Error: Missing Dependency: php = 4.3.9 is needed by package php-sqlite Error: Missing Dependency: php-pecl(Xdebug) is needed by package php-pear-PHPUnit2 Error: php-pecl-apc conflicts with php-mmcache Error: Missing Dependency: php = 4.3.9 is needed by package php-mmcache Error: php-eaccelerator conflicts with php-mmcache While dependency issues aren't too bad (e.g. "yum provides MISSING_FILE"), what is the best way to start going through and finding these conflicts? While this is just a test box, I'd like to get a handle on how to solve this sort of thing before I have the same problem on a production server. I see that CentOS plus in on here. Might that have to do with PHP 4 dependencies not being on? Or does PHP 5 solve those dependencies?

Gnome desktop, workspaces and windows
by James B. Byrne 14 Mar '08

14 Mar '08

I was editing a file in gvim when I inadvertently pressed some key combination that caused the vim window to disappear from the desktop. I looked in ps and found that it was still running. Checking the tool bar at the bottom of my display I noticed that a large rectangle now occupied the second of four boxes on the extreme right hand side. Clicking on that box brought back the gvim instance but hid the other windows that I had opened. I discovered that these are gnome workspaces. So I continued to work. However, at some point while reading the workspace documentation I decided to click on the "hide all windows and show the desktop" button on the left hand side of the lower tool bar. This indeed cleared the desktop but it also emptied the second workspace and I cannot retrieve my vim instance which ps still shows as running. Questions: What key combination places the window with focus into another workspace? What key combination or other method moves it back into the primary workspace? Why did hiding all windows empty the alternate workspace? How do I get my vim instance back from wherever it is gone? Regards, -- *** E-Mail is NOT a SECURE channel *** James B.

Thunderbird: can't seem to install french spell checker
by Niki Kovacs 14 Mar '08

14 Mar '08

Hi, I can't install a french spell checker in Thunderbird. There's a link in Thunderbird's preferences, to download new dictionaries, but it's dumb. So I downloaded the dictionary manually (spell-FR.xpi) and installed it in Thunderbird using the 'Extensions' dialog. But the installed dictionary doesn't appear anywhere. Googled some over this problem, and it seems like this happens to quite some people. Anyone on this list successfully installed a non-english spell checker in Thunderbird? Cheers, Niki

Recommendations for a “real RAID" 1 card on Centos box
by Therese Trudeau 14 Mar '08

14 Mar '08

Hi, I'm considering setting up my Centos Desktop machine for RAID 1. I read a lot of good info at this site:http://linuxmafia.com/faq/Hardware/sata.html#intel-vitesse about differences in fakeraid and real raid cards. The hardware I plan on installing this RAID card into is an Intel DP35DP motherboard with the Intel E4500 dual core processor, and I have two Mator 500 gig SATA hard drives. Can anyone recommend a good “real raid” card for my Linux? What I am looking for is to plug in a RAID controller card out of the box, and without having to load any drivers onto my Centos 5.1 box, have the Real hardware RAID card automatically do all the work, mirror my hard drive onto the second backup drive and do all the work for me. Do such cards exist? If so which model /manufacturers do you recommend? Any experiences/info/insights on hardware RAID cards good or bad on centos boxes would be appreciated. _________________________________________________________________ Climb to the top of the charts!

by Ross S. W. Walker 14 Mar '08

Therese, You are definitely making your life more difficult then is needed for a desktop machine. You said you have 4 hard disks. Make a software RAID1 out of the first two. Make a software RAID1 out of the second two and your good to go. You can use dump/restore to backup the logical volumes on the second RAID set to an LV on the first. No need for bare metal restore. Just need to get some working Linux distro to be able to read your files. Going HW RAID for your desktop is going to get in the way of you getting things going and if your HW RAID card fails then what? Your drives will only work with another identical HW RAID card. -Ross ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Fri Mar 14 09:08:39 2008 Subject: RE: [CentOS] Recommendations for a “real RAID" 1 card on Centos box >>> You can turn on write back caching if you have a UPS as well >>> (provided your UPS is wired into your system for a graceful shutdown) >>> >> >> Hopefully you have a redundant PS unit.

I've seen more > UPS failures than I've ever had failed PSUs on proper server grade hardware. This might be getting a bit elaborate for a desktop machine. I really want RAID because I'm tired every couple years of hard drive crashes and having to start from scratch and spending a week setting up new drives and getting my design software back on line and trying to recover data. What do you think of alternative back up systems, such as a tape backup with bare metal restore software? I'd go that route instead if I could fine a solution which would allow me to restore to different hardware, i.e. if my motherboard dies and I need to buy a different brand or model MB. I know Storix back up software has this capability - I use storix on my Linux server with RAID 1. @ home I have one Linux and one Windows desktop machine. _________________________________________________________________ Connect and share in new ways with Windows Live. http://www.windowslive.com/share.html?ocid=TXT_TAGHM_Wave2_sharelife_012008… CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

CentOS 5.1 install via PXE Failure
by James Gray 14 Mar '08

14 Mar '08

Hi All, This has to be something simple....but it's really busting my chops. We have a PXE boot server that is used for initial installation of a number of operating systems and it works well. However the CentOS 5.1 x86_64 install is seriously broken. We've made the PXE boot images available from "centos/5/os/x86_64/images/pxeboot/" in the tftp boot etc. We've rsynced our mirror with a local Tier 1 mirror (rsync://ftp.monash.edu.au::ftp/linux/CentOS/) Next we fire off the installation using the following in /tftpboot/pxelinux.cfg/default: label 4 kernel centos5/x86_64/vmlinuz append initrd=centos5/x86_64/initrd.img ramdisk_size=7000 ks=http://<insternal_install_server>/CentOS-5/dot/kickstart/ks.cfg.x86_64 ksdevice=eth0 language=en text The installer starts, loads the kickstart script (attached), successfully verifies the installation media, checks the dependencies for the packages to be installed, formats the hard drive(s), then attempts to download the package: sysklogd-1.4.1-39.2.x86_64.rpm At this point the installation will not continue because that package is not part of the installation! I've verified our internal mirror with 3 other Tier 1 rsync hosts and all agree, our images are up-to-date and the CORRECT sysklogd package is actually: sysklogd-1.4.1-40.el5.x86_64.rpm (Note the build is 40.el5, NOT 39.2). I've tried creating a symbolic link from sysklogd-1.4.1-40.el5.x86_64.rpm -> sysklogd-1.4.1-39.2.x86_64.rpm, and sourcing a real package for sysklogd-1.4.1-39.2.x86_64.rpm. These last two attempts have still resulted in the installer claiming the RPM is corrupt, not available etc. This is killing us :( The odd thing is the James -- There will be big changes for you but you will be happy.

FOSDEM Presentations
by Filipe Brandenburger 14 Mar '08

14 Mar '08

Hi! I was looking at the pictures and devroom of FOSDEM 2008 in www.centos.org. I was really interested in the presentations related to CentOS. Would you mind making them available somewhere on the site? I think that would be great documentation for some of the topics. In particular, I wonder what are Karanbir's opinions on "Hosting custom applications on CentOS 5", I guess I already know what many of the items will be (package everything in RPMs and manage them with yum), but I'm really curious about the other tips he would have to give. Thanks a lot! Filipe
