From: Lee W <centos-list(a)unassemble.co.uk> > Thanks for the heads up See my (now dated) "Dissecting ATA RAID Options" article in SysAdmin 2004 April. It covers 4 approaches to ATA RAID: - OS LVM (software) - FRAID (software) - microcontroller+DRAM (hardware) - ASIC+SRAM (hardware) > No, just another toy to play with. I'm currently looking a playing with > Software RAID but would like to have H/W as well. The only time I implement RAID-5 is for lots of reads. E.g., a MySQL server on the Internet. I prefer RAID-0+1 for most operations -- definitely system disks. RAID-3 is nice for desktop data and single user operations.** RAID-4 is best for NFS server and large file transfer servers (A/V). If I'm mega-anal on performance, I'll use multiple hardware RAID-0+1 cards on different PCI-X channels and volumes with a spanned RAID-0 LVM/LVM2 software volume across them. I would kill to have a HP DL585 with (3) Escalade 8506 cards, one on their own PCI-X channel, plus a 10GbE on the final PCI-X channel. [ **NOTE: For 32/64-bit I/O desktops, NetCell's 3 or 5-disc "RAID-XL" is actually the most ideal design I've ever seen. Instead of striped blocks, you have parallel reads/writes. ] > I'm certainly liking what I have seen of the 3Ware card's so far. Stock kernel support since version 2.2.15 (that's 2._2_ ;-). It's nice to be able to move volumes from older cards to newer ones without issue as well. > Their site lists quite a few distros as supported, including RHEL 3 which > from a simplistic guess would also mean that Centos 3 (and possibly 4) > would also be supported. Been using them in servers since Red Hat Linux 5.2. The drivers for most microcontroller or ASIC-driven hardware RAID are rather simplistic, because all the "intelligence" is on-board the card itself. 3Ware's 3DM/3DM2 management suite is a nice addition, although there have been some SCSI IOCTL changes that are rendering the older Escalade 6000 as deprecated. -- Bryan J.

New kernel causes kernel panic/unable to mount root
by Martyn Drake 10 May '05

10 May '05

Hi, I've just moved over to an Opteron 246 dedicated server and have used up2date to install the latest kernel (2.4.21-27.0.4.Elsmp). However, when the machine reboots it never comes back up and according to the datacentre technicians, this is what's happening: VFS: Cannot open root device"806" or 08:06 Please append a correct "root=" boot option Kernel Panic:VFS:Unable to mount root fs on 08:06 The technician then needs to reboot with the original kernel (2.4.21-27.0.2.Elsmp) to get it to work. Apparently there are no third party modules/drivers loaded. This didn't occur when I did exactly the same thing with a dual Xeon 3.06Ghz machine. Both machines use SATA drives. Any ideas? Any pointers are greatly appreciated. Incidently, lilo.conf currently looks like this: prompt timeout=50 default=linux boot=/dev/sda map=/boot/map install=/boot/boot.b message=/boot/message linear image=/boot/vmlinuz-2.4.21-27.0.4.ELsmp label=newlinux initrd=/boot/initrd-2.4.21-27.0.4.ELsmp.img read-only root=/dev/sda6 image=/boot/vmlinuz-2.4.21-27.0.4.EL label=2.4.21-27.0.4.E initrd=/boot/initrd-2.4.21-27.0.4.EL.img read-only root=/dev/sda6 image=/boot/vmlinuz-2.4.21-27.0.2.ELsmp label=linux initrd=/boot/initrd-2.4.21-27.0.2.ELsmp.img read-only root=/dev/sda6 Regards, Martyn

This seems like normal behavior to me. If by "cut myself to the internet", you mean physical disconnection (or all ports blocked), then how would ping receive a reply from google.com? You may be able to make DNS lookup requests, with dig or nslookup, but ping requires an actual connection to the address being queried, which it seems to be disconnected for you (dialup?).

Re: [CentOS] alias keeps changing (fwd)
by Michael Rock 10 May '05

Thanks. I ended up putting a NIC from a different name brand so they would not be identical. I did delete the garbage out of /etc/sysconfig but it did not work, perhaps if I tried deleting the entire config and starting over it may have worked. Now that I have both working how can you have two default gateways (one for each adapter) so they both service the separate IP networks independently of each other? I made sure ip forwarding is turned off in sysctl.conf. But with default gateway set on both they will not respond to outside requests. Discover Yahoo!

The newer autofs allows you to automount multiple systems. So you could have it mount a local share if the server isn't available, then automate rsync updates the local to the server when the server is detected. There are also other network filesystems that offer what you need. > RSYNC will not work, who many inconsistancies from files being created > and removed. I've never had this issue at all with my users. I maintain a "~/work" directory and a "~/worksync" directory. I know whatever I have in "work" stays on the server, and what is in "worksync" is synchronized between the local and the server. On the portables, work is a symlink to worksync, so they have no, non-synced storage. I really think this is more of a workflow issue than a technology one. > Will GFS work for my needs when they release U1 for CentOS? If > not, does anyone have any coda or intermezzo rpms for CentOS4? Hmmm, my use of GFS has always been very, very different. I guess it could be used for such though?

Mega-dittos there! Version control is wholly undervalued for everything, and solves the overwhelming majority of workflow and other issues -- even just for 1 person on their own (let alone multiple people working together). Hell, I'd just be happy if someone would do a "ci -l filename" before and after editing a file as root. RCS is so simplistic to use, yet so powerful for just standalone configuration file management. And ,v files are always importable to any other revision controll system. Of course, at the same time, I'm an evil man who _loves_ to catch people who modify /etc files, forget, but it leaves the system in a state that is not usable or at least not bootable the next time. By simply using rcsdiff from the last time I edited -- pointing out the changes, line-by-line, until someone fesses up. In reality, my ultimate goal is to get them to just do a "ci -l filename" as well, so they can revert to what they had before if needbe. > Subversion is a bit more efficient than cvs. It handles binaries inherently too, all will being CVS client syntax compatible. Combined with its WebDAV-DeltaV option via Apache 2, it's absolutely awesome for less technical users as well (who aren't commonly CVS familiar). > I haven't looked heavily at git or arch, but they have smart people working > on them. > Personal disk space is cheap...why not keep all revisions of your documents :) The great thing about modern, reverse-delta revisioning programs is that they don't eat up a lot of disk space either.

CentOS Convert Question
by admin＠dougware.net 10 May '05

10 May '05

Hi, First, I want to say that I have fallen in love with CentOS4. I have been using RedHat since the 5.x days. After RedHat dropped the stable system to go to a unstable system and a Enterprise system I felt like I was being left out in the cold. I quickly found out about WhiteBox and used it for quite a while. Then I learned about CentOS...and switched to it for my server needs. I have switched to CentOS4 and it is an awsome stable operating system. I just wanted to add my praise before I asked my question. I need a network based distributed operating system, something like Intermezzo or Coda to keep two servers in sync on one partition. I have a server at work and at home that I want to keep a MyDocuments partition in sync. NFS will not work because I need a offline or online solution. RSYNC will not work, who many inconsistancies from files being created and removed. Will GFS work for my needs when they release U1 for CentOS? If not, does anyone have any coda or intermezzo rpms for CentOS4? Thanks again, Doug Eubanks admin(a)dougware.net

Re: [CentOS] alias keeps changing (fwd)
by Maciej Zenczykowski 10 May '05

I'd suggest looking around the ifcfg-eth* files (somewhere in /etc/sysconfig/network-scripts I think) nad commenting out HWADDR= lines, if that works, then try reversing the HWADDR lines - this will reverse the numbers of the ethernet cards (ie making eth0 eth1 and eth1 eth0) but should result in a stable configuration till next hardware change. And you problem? IMHO, when the system boots up, one card gets the name eth0, the other eth1, when checking HWADDR the first eth0 card matches the ifcfg-eth1 HWADDR MAC address and is thus renamed to eth1, which fails, since eth1 already exists, and thus gets a random name, while the second eth1 matches the ifcfg-eth0 HWADDR MAC address and is thus renamed to eth0. In the end the physical eth1 is eth0 and the physical eth0 gets a random dev* name. This should probably be fixed sometime... first rename all devices to random names and only afterwards rename then to eth* according to the configuration files. Cheers, MaZe. PS. alternatively you can open the case and switch the two network cards, they'll be detected in reverse order and the previous renaming problem should vanish.

CentOS 3.3 is gone
by John Newbigin 10 May '05

10 May '05

Now that http://mirror.centos.org/centos-3/3.3/updates/i386/RPMS/ is gone (be it by design or error) I assume that all the patches for a CentOS-3.3 box can be found in http://mirror.centos.org/centos-3/3.4/updates/i386/RPMS/ Can anyone confirm this? In other words, Does the 3.4 updates directory contain updates to 3.3 and 3.4? If the answer is Yes: Good. Now what about 3.1? Should those updates be in the 3.4 directory as well? If the answer is No: What am I meant to do with my CentOS-3.3 media? I can not install with it anymore because I can't get patches. The management of these update directories always causes me confusion though it should be simple.

DNS configuration problem
by James B. Byrne 09 May '05

09 May '05

I have introduced some error in my dns resolution and I would like some help fixing it as I cannot seem to detect what I have done wrong. Briefly the setup is this: name servers: DNS01 - 216.185.71.33 DNS02 - 209.47.176.33 DNS03 - 216.185.71.34 DNS04 - 209.47.176.34 - offline DNS01 is a master DNS02-04 are slaves of 216.185.71.33 All are listed as authoritative for the zone test.com The following tests are run from a caching name server configured to forward queries as follows: /etc/resolv.conf search hamilton.harte-lyne.ca harte-lyne.ca harte-lyne.com halisp.net nameserver 0.0.0.0 nameserver 216.185.71.33 nameserver 209.47.176.33 Extract from /etc/named.conf ... forwarders { 216.185.71.33; 209.47.176.33; 216.185.71.34; 209.47.176.34; }; forward first; }; ... The intent of our setup is that if any server goes offline then the remaining servers will continue to answer queries. To further protect against outages DNS02 and DNS04 (currently offline) are on a separate netblock at a physically remote location. However, this is not what appears to happen when I test it. This are the results that I get when DNS01-03 are all online together. # dig @a.root-servers.net pop3.test.com +trace ; <<>> DiG 9.2.1 <<>> @a.root-servers.net pop3.test.com +trace ;; global options: printcmd . 518400 IN NS C.ROOT-SERVERS.NET. . 518400 IN NS G.ROOT-SERVERS.NET. . 518400 IN NS F.ROOT-SERVERS.NET. . 518400 IN NS B.ROOT-SERVERS.NET. . 518400 IN NS J.ROOT-SERVERS.NET. . 518400 IN NS K.ROOT-SERVERS.NET. . 518400 IN NS L.ROOT-SERVERS.NET. . 518400 IN NS M.ROOT-SERVERS.NET. . 518400 IN NS I.ROOT-SERVERS.NET. . 518400 IN NS E.ROOT-SERVERS.NET. . 518400 IN NS D.ROOT-SERVERS.NET. . 518400 IN NS A.ROOT-SERVERS.NET. . 518400 IN NS H.ROOT-SERVERS.NET. ;; Received 436 bytes from 198.41.0.4#53(a.root-servers.net) in 750 ms com. 172800 IN NS A.GTLD-SERVERS.NET. com. 172800 IN NS B.GTLD-SERVERS.NET. com. 172800 IN NS C.GTLD-SERVERS.NET. com. 172800 IN NS D.GTLD-SERVERS.NET. com. 172800 IN NS E.GTLD-SERVERS.NET. com. 172800 IN NS F.GTLD-SERVERS.NET. com. 172800 IN NS G.GTLD-SERVERS.NET. com. 172800 IN NS H.GTLD-SERVERS.NET. com. 172800 IN NS I.GTLD-SERVERS.NET. com. 172800 IN NS J.GTLD-SERVERS.NET. com. 172800 IN NS K.GTLD-SERVERS.NET. com. 172800 IN NS L.GTLD-SERVERS.NET. com. 172800 IN NS M.GTLD-SERVERS.NET. ;; Received 506 bytes from 192.33.4.12#53(C.ROOT-SERVERS.NET) in 38 ms test.com. 172800 IN NS dns01.harte-lyne.ca. test.com. 172800 IN NS dns02.harte-lyne.ca. test.com. 172800 IN NS dns03.harte-lyne.ca. ;; Received 107 bytes from 192.5.6.30#53(A.GTLD-SERVERS.NET) in 41 ms pop3.test.com. 38400 IN CNAME imap.test.com. imap.test.com. 38400 IN CNAME imap.halisp.net. imap.halisp.net. 38400 IN CNAME imap-07.halisp.net. imap-07.halisp.net. 38400 IN CNAME imap-07.harte- lyne.ca. imap-07.harte-lyne.ca. 86400 IN CNAME inet07.hamilton.harte-lyne.ca. inet07.hamilton.harte-lyne.ca. 86400 IN A 216.185.71.27 harte-lyne.ca. 86400 IN NS dns01.harte- lyne.ca. harte-lyne.ca. 86400 IN NS dns02.harte- lyne.ca. harte-lyne.ca. 86400 IN NS dns03.harte- lyne.ca. harte-lyne.ca. 86400 IN NS dns04.harte- lyne.ca. ;; Received 329 bytes from 216.185.71.33#53(dns01.harte-lyne.ca) in 2 ms However, if named on DNS01 is stopped and left running on DNS02 and DNS03 then this happens: ]# dig @a.root-servers.net pop3.test.com +trace ; <<>> DiG 9.2.1 <<>> @a.root-servers.net pop3.test.com +trace ;; global options: printcmd . 518400 IN NS I.ROOT-SERVERS.NET. . 518400 IN NS E.ROOT-SERVERS.NET. . 518400 IN NS D.ROOT-SERVERS.NET. . 518400 IN NS A.ROOT-SERVERS.NET. . 518400 IN NS H.ROOT-SERVERS.NET. . 518400 IN NS C.ROOT-SERVERS.NET. . 518400 IN NS G.ROOT-SERVERS.NET. . 518400 IN NS F.ROOT-SERVERS.NET. . 518400 IN NS B.ROOT-SERVERS.NET. . 518400 IN NS J.ROOT-SERVERS.NET. . 518400 IN NS K.ROOT-SERVERS.NET. . 518400 IN NS L.ROOT-SERVERS.NET. . 518400 IN NS M.ROOT-SERVERS.NET. ;; Received 436 bytes from 198.41.0.4#53(a.root-servers.net) in 37 ms dig: Couldn't find server 'I.ROOT-SERVERS.NET': Name or service not known So.

Kernel bug in software RAID?
by Matt Lawrence 09 May '05

09 May '05

After doing lots of research, it seems that there is a known bug in the software RAID for various versions of the 2.6 kernel. It seems to be affecting a system that a friend of mine has put together, so I'm guessing that RH has not back ported a fix into the released kernel. Does anyone here have any idea when a fix will make it into the CentOS4 distribution? Matt Lawrence "Your friendly neighborhood sysadmin" 512.838.2645 T/L 678-2645 512.351.1061 (cell)

Centos 4, bind slow responses when no cache
by Ted Kaczmarek 09 May '05

09 May '05

I have a Centos 4.0, bind-9.2.4-2 as a master and and FC2 bind-9.2.3-13 slave setup. Their seem to be a delay on the Centos 4 when asking for anything that is not in its cache. Doing some tcpdumps I see the AUTH response came back, but like a 3 second delay after that before server sends response to client. Both server have the same config other than one being a master and the other a slave. Their are no delays on the FC2. Googled on this with no joy. Any ideas? Ted

Non Distro Repositories ( Addons / Extras / Contrib / CentOSPlus )
by Karanbir Singh 09 May '05

09 May '05

The aim of this post is to try and explain the non-distro specific repositories hosted and run by CentOS. Aside from the main Distribution repositories ( OS, Updates, ISO's ) we also run the following repositories for each Release. 1. Addons : Contains packages required in order to build the main Distribution or packages produced by SRPMS built in the main Distribution, but not included in the main Redhat package tree (mysql- server in CentOS-3.x falls into this category). Packages contained in the addons repository should be considered essentially a part of the core distribution, but may not be in the main Redhat Package tree. 2. Extras : Packages built and maintained by the CentOS developers, that add functionality to the core distribution. These packages have undergone some basic testing, should track upstream release versions fairly closely and will never replace any core distribution package. 3. Contrib : Packages contributed by the CentOS Users, which do not overlap with any of the core Distribution packages. These packages have not been tested by the CentOS developers, and may not track upstream version releases very closely. 4. CentOSPlus : Packages contributed by CentOS Developers and the Users. These packages might replace rpm's included in the core Distribution. You should understand the implications of enabling and using packages from this repository. ---- We welcome contributions into the Contrib and CentOSPlus repository. Post a message on the CentOS-Devel mailing list with details of packages you would like to contribute, one of the CentOS developers will then pick it up and work with you on the issue. You might want to make sure that the same package is not already easily available from some other mainstream repository. And, you should be willing to maintain the packages in sync with upstream releases and fix's. -- Karanbir Singh : http://www.karan.org/ GnuPG Public Key : http://www.karan.org/publickey.asc

For Ext3, I have switched to Jorg's STAR because it has done POSIX ACLs for awhile. But when I want to use dump, I have switched to XFS (and its xfsdump), since 2001. You can install with XFS from the installer. The nice thing about XFS, like Ext3, is that it hasn't changed in structure since the mid-'90s. Unlike IBM JFS, which was ported from OS/2 instead of AIX (largely because of Project Monterey -- see any full and accurate history on the SCO v. IBM lawsuit for more on the reasons why) and lacked a lot of the UNIX/inode structures, XFS was ported directly and fully from Irix to Linux. Which means that POSIX ACLs, Quota, NFS and other things worked off-the-bat in Linux. In fact, the SGI XFS team was responsible for a _lot_ of the new VFS interfaces of 2.5.3-onward, largely because they had already ported them from Irix to Linux for XFS support. I.e., a lot of the new features of the Linux 2.6 kernel at the VFS that _all_ filesystems benefit from were from Irix's XFS codebase. As of Linux 2.6 (and late 2.4.25+ kernels?), all of the core support structures that XFS needs are now standard. Other than one bug in XFS 1.0 (fixed some 3 years ago, resulting in the XFS 1.1 release), XFS has been rock-solid and reliable for me. The only major thing that had to change from Irix to Linux was the default block size (to match the default paging of the x86 architecture from MIPS). -- Bryan J. Smith mailto:b.j.smith@ieee.org

Dell Poweredge 4300 + PARC 2 (Megaraid) Centos 4
by William Suffill 09 May '05

09 May '05

After 4 days of agrevation I felt it was best I post to the list before I break something or hurt myself. It seems that 2.6 from other posts seemed to kill support for this card in particular since LSI has EOL'd it. Although I've managed to download megaraid-2.00.3 which does support this card and build an object on a sperate box. Although the installer seems to require a driver disk and a .ko (kernel object). I'm pretty much at a loss as to where to go from there. I've never built a driver disk so it's been and uphill struggle just to get this far. It's been some long days for both techs here and seems to get so far but not far enough since the box is still unusable. I much rather solve this issue then run a legacy distro that will pick up the card as is so any assistance would be greatly appreciate. -- William

Removing custom kernels?
by Preston Crawford 09 May '05

09 May '05

Is this possible. I did my first one yesterday in order to get my iPod mini to work with the EL kernel. It worked well. Everything went smoothly, but I don't like what I named it. So I'd like to take one more shot at it. If I do, is there a way to remove the old one cleanly? Modules and everything. Also, if do recompile the kernel again, do I need fresh source, or can I just do a make clean, rename the setting in the Makefile for the name, then go through all the usual steps. Thanks, Preston

Time is Fleeting: CentOS 4 question
by Bill Diamond 09 May '05

09 May '05

I have recently built a new server using CentOS4. I've found one major oddity: time resolution is completely whacked. I'm not using an external time source nor am I relying on NTP for time resolution. For some reason, time on this server moves forward at a far more rapid rate. Right now, all my other systems show Sunday May 8, 3:19 pm. The CentOS server thinks its Monday May 9, 3:54 pm. I just reset it about four hours ago to the correct time. I'm using an inexpensive eMachines T6212 AMD Athon 64 processor and 1 GB RAM. Can anyone suggest a reason why this server thinks it's 25 hours in the future and growing more distant with each minute? Thanks, Bill -- Bill Diamond <bill(a)billdiamond.com>

Greetings, I have need of a newer ZLIB and/or maybe the ZLIB-DEVEL. I need 1.2.2 or later and was told to go to www.zlib.net On that site, it mentions... zlib for Linux, both shared and static plus headers (RPM format, many architectures) so what I am wondering is this, is there a new ZLIB coming down the "upstream" pipe now or quickly? if there a specific YUM command to snag from another repository(ies) that you and the developers trust? if not, which one should I grab from www.zlib.net that will not cause me any future problems with "yum" or any other situations etc?

OpenOffice Conversion

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 List, I have a rather unique question, that perhaps can be answered easily here.I did search google and only came up with one app that does this exact thing; however, it's an expensive tool. Thusly, not my cup of tea. I have need to convert approximately 100 documents in Openoffice's native format to Microsoft Word's native format. Apparently, someone's manager wants all of the documents in Word (just this once) for whatever reason and going back and saving each individual file as a Word document seems excessive.

passwordless ssh
by rado 07 May '05

07 May '05

Hi, I am just migrating to Centos from fedora core 3. I have 3 boxes involved here: Box A --Fedora 3 (doing the dns, http, sendmail serving duties) Box B --CentOS Box C --CentOS I used to run root passwordless ssh both ways from boxes A and B mainly set up to keep the 2 boxes in sync w/rsync ... these 2 boxes normally ran one being the slave and the other being the master...the master did all the serving duties...if something happened where the master couldn't do it anymore, then the slave becomes master. I have tried and tried the following #ssh-keygen -t dsa (and rsa using authorized_keys(2) or both depending...) when it asks for passphrase...just enter and enter # scp /root/.ssh/id_dsa.pub boxA:/root/.ssh/ # ssh boxB #<password> boxbshell # cat /root/.ssh/id_dsa.pub >>/root/.ssh/authorized_key or key2 or both. # exit boxashell # ssh boxb <password> will NOT let me do passwordless now then I have gotten it to work by using the following /root/.ssh/.config : Host remotehost User remoteuser Compression yes Protocol 2 RSAAuthentication yes StrictHostKeyChecking no ForwardAgent yes ForwardX11 yes IdentityFile /home/localuser/.ssh/id_remotehost_dsa taken from: http://www.davz.net/static/howto/sshkeys I can get it to work from 2 boxes both ways...but when I set up the 3rd box, it works but one of the other boxes that was good does not do it anymore. I go back edit the authorized_key files.... check the other boxes make sure they still work set up the faulty box again...get it working then one of the other good boxes doesn't work I then start looking into the .config file...has some pretty dangerous things in it that I really don't care for but that's where I am right now. does anyone know of anything specific that Centos is doing here? or what can be my problem?

X stopped working after compiling new kernel
by first last 07 May '05

07 May '05

Hi again, After quite a few stability problems with CentOS 4 and my laptop I have decided to go back to Centos 3. I installed it and got everything working alright, apart from the wireless network card. I need to use ndiswrapper and so require a newer kernel (2.4.26 at least), so I downloaded the kernel source 2.4.30, copied the right configuration (config-i686), made oldconfig and installed the kernel. Everything boots alright but X complaints about invalid checksum in the video bios. Searching for this error message it mentions that I should enable agpgart and support for my card (i852 or so) in the kernel, but it is already supported (I have tried it as a module and compiled right in). Anyone got any suggestions on how to get X working again? Do I need to get any extra RHEL patches before I can compile the code? Any help will be greatly appreciated.

New to CentOS, is this a safe bet?
by Preston Crawford 07 May '05

07 May '05

I know this may be a stupid place to ask, but I have to ask. I'm looking for a new Linux distro to use and support. I've been a loyal purchaser of SuSE Linux Pro for the last 3 years. I've paid my $90 loyally, in part because I wanted money to actually go to someone working on OSS, but also because I thought it was a good bargain, to get a quality, tested distro for that cost. The problem is that lately SuSE is sliding down the path towards being considered Fedora-like by Novell. So when I install SuSE I don't know if I'm going to get security updates next week or the week after. My $90 may have just gone to be a 6-month or 1-year beta tester. I need more stability than that. So I'm considering CentOS based on some articles I've read lately, as my solution. What I'm looking for is a good solid distro that COULD do some multi-media if I go hunt down the RPMs or if there's a YUM repository (I'm familiar with Fedora), but mostly a solid distro where I can do Java work daily and where the distro is memory efficient, solid and stable. And also where if I decide to run it for a year or more I won't be forced to upgrade. Now I believe CentOS promises all of these. My concerns, in terms of it being a safe bet are... #1 - Is there any reason to fear Red Hat bringing the hammer down and thus ruining the party? I'd love to see an FAQ or something to the effect that legally there's no way for Red Hat to block what CentOS is doing. #2 - Is the community strong? I'm new to the community and when I look on distrowatch it's way down the list. But is this accurate or is CentOS picking up steam? I get the feeling it's picking up steam. The reason this is important is because I'd hate to pick it only to watch it wither and have to go distro-hopping again. Once again, looking for stability. Any responses that can help me decide are appreciated. Thanks. Preston

problem with swap and upgrade to 4 from 3.3
by Peter Farrow 07 May '05

07 May '05

Dear All, I've tried to upgrade a Centos 3.3 installation to 4.0 using YUM and some instructions I found in a thread on the Centos Forum. The initial problem I had with Python 2.3/2.2 has been resolved, and now I am trying to upgrade the kernel to 2.6 prior to the yum upgrade, unfortunately it bails out at the end with dependancy erros on Xfree86. At this point I decided to use the CDs with a the "upgradeany" option. This went fine initally but then bails out with a swap error, this is because swap on this machine is on /dev/md2 (a mirrored set) and this was not set up at the original install time, as all the other partitions were: when the machine was installed, one of my staff did not set the swap up mirrored, so I had to mirror the swap partition manually after the original install. This works fine, but the machine cant enable the swap at boot becuase it does this prior to enabling the RAID subsystem, so the swap startup fails, but once the machine is up, the swap is actually running without any manual intervention. Its this error, that stops anaconda from upgrading the OS from the CDs I note on other machines I have installed when the swap was mirrored on the original install, it still appears to enable swap prior to the RAID subsystem, without any errors. So I guessed this might be a problem with the ram disk image, so I created a new one using mkinitrd, but the swap still fails at startup, thus preventing me from using the CDs to upgrade the box. I guess I could set the swap back to an unmirrored set, run the upgrade from the CDs then mirror it again, but this is not ideal, does anyone have any suggestions as to how to fix this little RAID niggle with the swap caused by not RAIDing the swap parition originally on install?

Re: imap on Centos 4 -- UW IMAP 2004b for FC3/RHEL4

From: Matt Hyclak <hyclak(a)math.ohiou.edu> > Actually, the more direct replacement would be Dovecot. > Cyrus can be complicated to set up and get running. I actually modified the old UW IMAP 2002 SPEC file from RHL9/FC1, and modified a few config files, to support UW IMAP 2004b. I made one with both RFC3501 (no text passwords over SSL) and non-RFC3501 (legacy, text passwords allowed over SSL). I originally released it for Fedora Core 2, e.g. (links no longer work): https://www.redhat.com/archives/fedora-list/2004-August/msg01501.html I have updated it for UW IMAP 2004b on FC3/RHEL4. The only kicker right now is that it is a single set of RPMs, without the client and server in separate RPMs. That will cause a conflict with the client-only UW IMAP package that normally comes with FC2+/RHEL4. One of these days I'll break the client from the server portion in the SPEC file, and host my own APT/YUM repository so it will work with APT/YUM and not generate conflict. But until then, if anyone wants my version, let me know. I try to keep up with UW IMAP releases as vunerabilities are found. The SPEC file only needs to be modified slightly on each new version. -- Bryan J. Smith mailto:b.j.smith@ieee.org

OT: P4 Vs Xeon for Linux
by Nigel Kendrick 06 May '05

06 May '05

I have just had delivered a new HP Proliant server and it is based on an Intel Xeon 2.8GHz processor. On site already we have an Acer Altos G310 with a P4 2.8GHz processor. The new HP server was destined for another site with about 30 persons to service some simple file and print sharing and to manage their email (postfix + MailScanner). The Acer is hosting our Intranet, file and print sharing and soon to have our email + bacula backup services for potentially 250 users. Performance wise, would it be worth the small effort to move the Intranet etc. onto the Xeon-based server and ship the P4 to the other site or will the potential performance gains not be significant? Any insight appreciated. Thanks

ACLs iin Centos 4
by Peter Farrow 06 May '05

06 May '05

Hi There, It seems the default installer with Centos 4, enables DACs and the extra ACLs which DUMP cannot handle.... so I get errors like "DUMP: ACLs in inode #nnnn won't be dumped" since DUMP and RESTORE is integral to my back policy for some 30+ machines I would like to know if its possible to turn off the extra ACLs in the file system as I really don't need them... Can tune2fs do this for me or do I have to re-build the filesystems with some option that I currently don't know... P.

YUM - Did directories change on the mirrors?
by Gerry Lachac 06 May '05

06 May '05

I didn't see this in the mail archives, maybe I missed it. I'm running CentOS 3. It looks like the $releasever directory has been dropped from mirrors.centos.org. This just happened in the last week (I run a daily cron to check for updates) My yum.conf (for CentOS 3) has url's defined like: baseurl=http://mirror.centos.org/centos-3/$releasever/addons/$basearch/ But when I run yum I get errors: Server: CentOS-3 - Addons retrygrab() failed for: http://mirror.centos.org/centos-3/3/addons/i386/headers/header.info Executing failover method failover: out of servers to try Error getting file http://mirror.centos.org/centos-3/3/addons/i386/headers/header.info Using my browser I see that this URL doesn't exist: http://mirror.centos.org/centos-3/3/addons/i386/headers/header.info But this does (notice the 3/ is missing): http://mirror.centos.org/centos-3/addons/i386/headers/header.info Is this a permament change or a temporary one due to server updates?
