Is parralel processing automatically done on multi-core CPU's?
by Rudi Ahlers 06 Mar '10

06 Mar '10

Hi, I just noticed this article, http://www.howtoforge.net/fully-utilizing-your-x-core-cpu which uses http://code.google.com/p/ppss/ for parralel processing. So, can anyone tell me if parralel processing happens automatically on CentOS, or would I need to use this script as well? We mainly have Dual Core & Dual CPU, Dual Core (i.e. 8 cores) servers and it would be benefitial to know whether any applications on the server could automatically use all 8 cores, or whether I need todo something on the servers to get this working? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Hi. Any suggestions how I can get a video driver for my ThinkPad T61 laptop? I've got CentOS 5.4 on it but Xorg crashes when I try to change resolution, and Xorg.log has: (WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found (--) PCI:*(0:2:0) Intel Corporation unknown chipset (0x2a02) rev 12, Mem @ 0xf8100000/20, 0xe0000000/28, I/O @ 0x1800/3 (--) PCI: (0:2:1) Intel Corporation unknown chipset (0x2a03) rev 12, Mem @ 0xf8200000/20 I didn't find one on the vendor's website.

old package location?

After an update to 5.4, squid seems to no longer let you override Cache-Control: no-cache headers in a refresh pattern so I need to go back to an older version. But I've forgotten where the archive of old rpms lives... -- Les Mikesell lesmikesell(a)gmail.com

Intrusion Detection
by Dan Burkland 05 Mar '10

05 Mar '10

Hello all, I have been exploring the various intrusion detection systems available for the Linux platform and was wondering what ones you all would recommend? I have used AIDE before and while it is extremely easy to setup, it does not support the ability to send alerts as files are changed (allows one to be aware of an intrusion almost immediately). Thank you, Dan Burkland

ImageMagick Bug
by Michael A. Peters 05 Mar '10

05 Mar '10

Hello, I am experience a segfault while trying to use convert between svg and png. I suspect that the bug I am experiencing is identical to this one: https://bugzilla.redhat.com/show_bug.cgi?id=472253 I can try the suggested patch myself, but is this the kind of thing that maybe could be patched in CentOS plus repository until RHEL has an approved patch? The report looks several years old yet there still isn't one, which isn't a good sign. The issue I'm dealing with, on my web site I am moving a lot of the currently gd generated dynamic png images to svg but since not all browsers support svg, I need to convert from svg to png for a fallback. I suspect I'm not the only one who wants to do this sort of thing, so segfault in convert from svg to gif/png is really something that probably should have a fix readily available. I'm running CentOS 5.x

Hylafax does not pick up.
by James B. Byrne 04 Mar '10

04 Mar '10

We run the distro HylaFax on a CentOS-5.4 host. On infrequent occasions we notice that the server will not pick up an incoming call. It reports listening to modem rings. Now, it seems to me that picking up the call should be under the control of the modem but I notice that there exists a setting in Hylafax for the number of rings before picking up. The default value for this is 0 (zero) but we have it set to 1 (one). Because of this option I am not sure whether there is something wrong with the server or with the modem. Has anyone else experienced this problem and discovered its cause? -- *** E-Mail is NOT a SECURE channel *** James B.

Its just that disks with 100s or 1000s of gigabytes take a long long time to fully write. DBAN's default erase sequence is excessive for modern disks. the old DOD erase sequences were devised for media that used simple NRZ type encodings, with RLL encoding methods used by modern disks, they don't make any sense at all. all you really need is to write the disk with all 1s, then all 0s, and its about as good as it will get, not even CSI:Miami will find any actual data on it (of course, if the script writers need to, they'll invent data out of thin air).

Is this an rpm bug, a checkinstall bug, or PEBKAC (problem exists between keyboard and chair)? thanks, -Bob Beers

X server crashes when I fire up "Display" or "Screen Resolution" control panels

Hi. I've just installed CentOS 5.4 on my IBM T61 laptop. By default, I get the same image (duplicate screens) on the laptop's LCD and on the external monitor; I want to set up separate screens but my X server crashes when I start "Display" or "Screen Resolution" control panels or press Function-F7 which is supposed to bring up the single screen/ multiple screens selection menu. I am including my Xorg.log, could somebody help me sort this out, please, or at least point me in the right direction? I do see this: (WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found (--) PCI:*(0:2:0) Intel Corporation unknown chipset (0x2a02) rev 12, Mem @ 0xf8100000/20, 0xe0000000/28, I/O @ 0x1800/3 (--) PCI: (0:2:1) Intel Corporation unknown chipset (0x2a03) rev 12, Mem @ 0xf8200000/20 Do I need a special video driver?

I went on the vendor website but there is no driver available - they did have an NVIDIA driver for SUSE, but my laptop does not have an NVIDIA device and I am running CentOS, not SUSE! Help?

YESS. It prevents the tty error from showing up and asks me for a password as expected. BUT, how do I then automate the entering of the password? John Kennedy mentioned using expect which I've used before but found it to be 'finnicky'. I may have to look at it again... Changing settings such as sudo configuration or ssh config may be daunting since I have a large number of systems(150+) that would need to be modified. :-/ --Tim

Resync raid1 from disk with unreadable sectors
by Mindaugas Riauba 04 Mar '10

04 Mar '10

Hello, After some fiddling with the server now I have broken RAID1 with the "current" mirror on the disk with few unreadable sectors. If I try to re-add other disk to the mirror resync goes till those bad sectors and then starts from the beginning. And so on. Is it possible to somehow force resync to continue even after errors? Manual resync with dd would require a bit too long downtime. If it is impossible to force resync I'll probably manually rsync all the files from the old broken disk to the new one. Mindaugas

splash screen resolution
by Michael Klinosky 04 Mar '10

04 Mar '10

I installed CentOS 5.3 on a desktop box, and I'm having a problem with the splash screen resolution (during bootup). I suppose that it somehow got configged when I set the GUI's screen (I run in level 5). I think that, in finding the highest res for the GUI, I went past the monitor's capability. But it's good now. During boot, I get a funny 'double' display (2 pointers, 2 sets of text). I can't find where to change it (thru the gui or manually). And, yes, I did try searching (on google.com/linux and the CentOS wiki). I didn't see anything in /boot/grub/grub.conf that would set the res. I read about removing 'rhgb'; I tried it, and at least it uses an appropriate resolution. But, I'd like to use the graphical boot screen. How do I fix this?

SSH Remote Execution - su?

Greetings All- I'm about to embark on some remote management testing and need a way to login to a remote system running CentOS 4.x/5.x via SSH, su to root (using a password), then execute a command. I currently login to the boxes using key based SSH like this: ssh -i ~/remote_key admin@$REMOTEIP Then, I SU to root. However, if I try to do this automatically like this: ssh -i ~/remote_key admin@$REMOTEIP 'su -l' I'm getting: "standard in must be a tty" So, how am I able to remote login using SSH, su to root, then execute a command as root? All comments and suggestions welcome. Thanks! --Tim

Recover RAID
by Jeff Sadino 04 Mar '10

04 Mar '10

Hello Everyone, First time CentOS poster :) I have CentOS 4 installed on the head node of a Sun Gridengine cluster set up in a RAID. The head node has four hard drives, and I assume that drives 1 and 2 are in a raid and then drives 3 and 4 are in another raid. I was trying to expand the OS partition on drive 1 because it was full. I took drive 1 out, put it in my Fedora 8 box as a secondary drive, booted up into Fedora, and saw it had the partition structure: / 8GB /var 4GB /swap 1GB and an "unknown" partition 101.4GB I did a cp -rfa on the / and /var files for a backup (I know, not the best way). Restarted my Fedora into Windows to take a look at it using Paragon Partition Manger. Restarted into Fedora and using gparted, formatted the "unknown" partition as ext3 - I think that is where I made my fatal mistake - and moved the /swap to the middle of the drive, moved the /var to the middle and expanded to 10GB, and then expanded / to about 50GB to fill up the rest. I had also took drive 2 out of the head node and into my Fedora, and saw it had the partition structure: /swap 15GB and an "unknown" partition 101.4GB Ok, now when I put everything back into the head node, and reboot, the BIOS sees all four drives, and from what I can tell, recognizes the first raid (of drives 3 and 4), but says it can only find one disk for the second raid (drives 1 and 2). I can't find any way around this. Looking at my /etc/raidtab file: raiddev /dev/md0 raid-level 1 nr-raid-disks 2 nr-spare-disks 0 persistent-superblock 1 device /dev/sdc1 raid-disk 0 device /dev/sdd1 raid-disk 1 raiddev /dev/md1 raid-level 0 nr-raid-disks 2 persistent-superblock 1 chunk-size 4 device /dev/sda4 raid-disk 0 device /dev/sdb2 raid-disk 1 It says it can bring up md0 ok, but not md1. Right now, I am going to try to restore the "unknown" partition that I deleted from drive 1 using the "unknown" partition from drive 2. Any ideas on how to get myself out of this mess? I feel like I really messed it up good. This is a server for our work, and we have a couple years worth of data on it, so I would really like to fix it rather than reinstall. Thank you greatly for any help! Jeff Sadino

Hi All, I have a new system that is dual AMD's. I have a CentOS 5.4 x64 dvd. I power on the machine It boots to the CentOS media I had in the dvd drive I start the install it comes up and asks me where I have CentOS, I select 'Local CD' and I get that a message saying CentOS install files cannot be found. Strange because it boots to it! What could be the issue? I have 1 320gb Sata Drive connected to onboard Sata and that is where I want to install. The DVD drive is connected IDE to the mobo I have two 3ware raid cards each can handle 8 drives, but I have not put drives in yet. I am just trying to make sure everything works before I go that route. The 16 drives will be storage only. Linux Software Raid. Any thoughts? -Jason

help with a dd bug
by Adrian Buciuman 03 Mar '10

03 Mar '10

Hi, Can somebody reproduce this bug? http://bugs.centos.org/view.php?id=4220 dd if=/dev/zero of=/dev/my_usb_stick_device_name bs=4096 count=10000 can not be stopped with ctrl-c and is not responding to signals (count=10000 can be modified to give you enough time to test) The bug has been closed with the following comment: "As said: dd is in an uninteruptable state when you do that. This is not a bug" This is wrong, because IMHO dd should receive the signal after it finishes the current read()/write() and returns to user space, but this is not happening. How can I reopen the bug? Thanks Adrian Buciuman

Anyone familiar with it? If so, a few questions: - is there one head server, so that anyone referring to the f/s talks to that server? - how transparent is FUSE to existing programs, or should I just use NFS? - how's the performance? mark

How do I create a new menu category in GNOME ?
by Niki Kovacs 03 Mar '10

03 Mar '10

Hi, The title says it all. My GNOME desktop is in French, so here's what my standard Applications (same word in french) menu looks like : Applications > Accessoires (Utilities) > Bureautique (Office) > Graphisme (Graphics) > Internet (Internet) > Son et vidéo (Sound and Video) Now I'm currently installing a medical application (Medintux) which consists of several different "modules", e. g. programs where each one does one thing. There are something like ten different modules, and I'd like to create a new category in my main menu, so I have : Applications > Medintux > User Management > Diagnostics > X-Rays > Scanner management > Prescriptions > ... Something like that. I'm already familiar with creating *.desktop files and putting them in /usr/share/applications and running update-desktop-database. But I can't seem to be able to create a new category. I found some probably related files in /usr/share/desktop-directories and tried to edit my custom medintux.directory file, but to no avail. Anyone here familiar with the innards of GNOME desktop menus? Cheers, Niki

DHCP client not working with Windows DHCP / dynamic DNS server
by Florin Andrei 03 Mar '10

03 Mar '10

# Broadcom Corporation NetXtreme BCM5754 Gigabit Ethernet PCI Express DEVICE=eth0 BOOTPROTO=dhcp HWADDR=00:22:19:XX:XX:XX ONBOOT=yes DHCP_HOSTNAME=centos.XXXXXXXXXX.local In this particular instance, it's a place where Windows is used for DHCP and DNS servers. :( I have no control over the Windows side of things. The Windows sysadmins claim I don't need a fixed IP address, because DNS will pick up the name after I make the DHCP request. The problem is, that doesn't happen, even though the DHCP client is correctly configured (see above). The system is vanilla CentOS 5.4, text-mode install, fully updated. I boot the CentOS system. Then, on another Linux machine, I do "host centos.XXXXXXX.local" and it returns host not found. However, if I do the same for other hostnames, DNS resolution works fine. Is there anything else I can do on my side to make it happen? Any particular options in dhclient.conf or something like that? -- Florin Andrei http://florin.myip.org/

Very unresponsive, sometimes stalling domU (5.4, x86_64)
by Timo Schoeler 03 Mar '10

03 Mar '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, please forgive cross posting, but I cannot specify the problem enough to say whether list it fits perfectly, so I'll ask on both. I have some machines based with following specs (see at the end of the email). They run CentOS 5.4 x86_64 with the latest patches applied, Xen-enabled and should host one or more domUs. I put the domUs' storage on LVM, as I learnt ages ago (what never caused any problems) and is way faster than using file-based 'images'. However, there's something special about these machines: They have the new WD EARS series drives, which use 4K sector sizes. So, I booted a rescue system and used fdisk to start at sector 64 instead of 63 (long story made short: Due to overhead causing the drive to do much more, inefficient writes when starting at sector 63, the performance collapses; with 'normal' geometry (sector 63), the drive achieves about 25MiByte/sec writes, with starting at sector 64 partition, it achieves almost 100MiByte/sec writes): [root@server2 ~]# fdisk -ul /dev/sda Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Device Boot Start End Blocks Id System /dev/sda1 * 64 2097223 1048580 fd Linux raid autodetect Partition 1 does not end on cylinder boundary. /dev/sda2 2097224 18876487 8389632 82 Linux swap / Solaris /dev/sda3 18876488 1953525167 967324340 fd Linux raid autodetect On top of those (two per machine) WD EARS HDs there's ``md'' providing two RAID1, /boot and LVM, as well as swap per HD (i.e. non-RAIDed). LVM provides the / partition as well as LVs for Xen domUs. I have about 60 machines running that style and never had any problems. They run like a charm. On these machines, however, domUs are *very* slow, have a steady (!) load of about two -- 50% stating in 'wait' -- and all operations take ages, e.g. a ``yum update'' with the recently released updates. Now, can that be due to 4K issues I didn't see, nestet now in LVM? Help is very appreciated.

Success moving Xen LVMs from 32 to 64bit host
by Kwan Lowe 03 Mar '10

03 Mar '10

Just wanted to share some success I had moving some Xen guests from one server to another. Problem Recap We had Xen host on a single core 32-bit CentOS 5.4 installation on an AMD Athlon 2.1 GhZ system that was giving hard drive errors and needed to move the LVM-backed Xen images to another server. The replacement server was a quad-core AMD Phenom system running 64-bit CentOS 5.4. Our original plan was to use LVM snapshots so that we wouldn't need a maintenance window. This worked fine in test, but we decided to bring down the Xen guests after all. After shutting down the systems we backed up the LVMs. To show the backing LV: lvdisplay /dev/rootvg/xm_c32_001 >From this, we grabbed the "Current LE" field and LV Size. We used LV Size to create a temporary mount point. We used the "Current LE" parameter to create an identically sized LV on the replacement server . On the failing server: dd if=/dev/rootvg/xm_c32_001 of=/mnt/backup/xm_c32_001.out We gzip'ed the resulting .out file and saved it as a backup. +++Footnote BTW, there are many recommendations to do the following on the virtual machine: dd if=/dev/zero bs=1024 count=xxxx of=/partition.out rm partition.out By creating the large empty file on each partition *in the guest istance* (/var, /, /home, etc.), it will improve the image compression. Space was not much of a concern and we were worried about blowing out a production system, so we opted not to do this. +++Footnote Once the backing LVM was created, we created the LV on the replacement server: lvcreate -l xxx -n xm_c32_001 rootvg Then used dd to recreate the file: dd if=xm_c32_001.out of=/dev/rootvg/xm_c32_001 Next, we copied the /etc/xen/xm_c32_001 configuration file to the replacement server. We generated a new UUID using the "uuidgen" utility. We also created a new MAC address. Finally, we started the instance: xm create xm_c32_001 Everything came up, but no network. From the root console we logged in then edited the /etc/sysconfig/network-scripts/ifcfg-eth0. Xen had apparently renamed the script and put in a DHCP configuration. We just renamed the backup file and commented out the MAC address line and restarted networking, *and* ifdown eth0 then ifup eth0. It took a few seconds for the network to properly discover the new MAC address. Once that was done, everything worked beautifully.

Wireless Made Easy (for Home Desktops)
by Ron Blizzard 02 Mar '10

02 Mar '10

For those of you who use a wireless router and may work on one or two (or even several) machines in your computer room, an AP Client is a nice solution. When you move to another machine you can just move the wireless net adapter to the new machine and you're up and running on the network immediately. I've been using a D-Link G730AP for a while -- but it's not really made for this -- it's a pocket adapter meant to carry with you laptop. And, unlike my old Asus WL-330, it won't hook up to a switch. Asus also makes a more powerful, larger, wireless AP/Client/Bridge/Reapeater, the WL-320gE. I bought two of these on eBay and they work great as Clients (network adapters) or "Stations" in Asus talk. They have a range of 850 meters (as compared to the pocket AP's range of 40 meters) so, in my room, I've got the full speed of my Cable wirelessly. It's three to four times faster than the D-Link G730AP, and it's solid (the D-Link was iffy). But, more importantly, I can hook it up to a wired (standard) switch and have as many simultaneous network connections as ports in the switch (in this case, four -- but I only use two). I've also set one up in the back of the house with a switch for my son's computers -- through several walls they're still getting very fast service. This is the only way I've used this device, but a lot of people buy them as repeaters. (I could mine up a repeater/client and my kids would have an even stronger single, but it's not necessary.) Another feature of Asus is that you can use it simultaneously as a bridge and as a wired client. It works well, the documentation is a bit inadequate, but it doesn't take long to "translate." Anyhow, I've rambled again. The reason I bring this up is that these things are currently selling for $25 on eBay -- which is about the cost of mid-range USB adapter. The seller has nearly 800 of them. (I have no relationship with the seller, except I'm a customer.) The eBay link is at http://tinyurl.com/ykysncw -- RonB -- Using CentOS 5.4

Virtual Machine Path Issue
by gene.poole＠macys.com 02 Mar '10

02 Mar '10

All, I'm running CentOS 5.3 x86_64 and I decided to install VMware Server 2.0.2 and all went without a hitch. I then created a Virtual Machine and used CentOS 5.4 x86_32 ISO image to build it. While I was customizing the built image, I attempted a 'find' command and received a message that the command could not be found. I checked root's path statement and found some strange entries (i.e. /usr/bini). Once I corrected those entries all seems to be working fine now. I don't have a physical platform to test the ISO on, so I must remain in the virtual arena. How can I tell if this is an error with the ISO or something going crazy during the VM build? Thanks, Gene Poole

kexec for CentOS 4?
by tony＠softins.clara.co.uk 02 Mar '10

02 Mar '10

I have a remote CentOS 4 machine on a network where I can't put a DHCP or PXE server, and I want to do a complete reinstall. So what I want to do is, from the currently-running system, to invoke an installation kernel and initrd in just the same way that GRUB would, giving it a boot command line that specifies a remote kickstart file, installation tree, and other required info. It looks like kexec is the right tool to do this, but I have only been able to find it for CentOS 5. Does anyone know where I could get kexec for CentOS 4? Does the CentOS 4 kernel support it? If not, are there any other ways to achieve what I've described? Thanks Tony -- Tony Mountifield Work: tony(a)softins.co.uk - http://www.softins.co.uk Play: tony(a)mountifield.org - http://tony.mountifield.org

Moving hard drives
by Slack-Moehrle 01 Mar '10

01 Mar '10

Hi All, I have a server that is running nicely, except I have hit the maximum RAM (4gb) and I wish to add more. It is an ASUS board, AMD X64 dual core, nvidia nic. What I want going to move to is a dell board, Intel Pentium M dual code, which supports 8gb of RAM. Can I just unplug the HD and move it to the new server and boot it up? I assume that the NIC will need to be re-setup, but what other issues would there be? I am not running X at all. Doing apache, zimbra, mysql. Best, -Jason

Rsync over ssh doesn’t works but a little cumbersome – customer’s servers’ data center are far away from development site and link between is slow. So better one to data center’s one and from the latter to all others in data center. This will work better but still could be improved. Since customer has some scripts to be reloaded after codes/data are synced. >You'd probably really want to wrap this with a version control system like subversion to get history, logging, rollback capability, etc. so Is there already an existing solution like this available, open source and commercial?

UnRAID

has anyone heard of UnRaid at: http://lime-technology.com/ Seems interesting, runs from USB. What I like is that you can add drives to your array without having to destroy it. And it lets you add any size drive that you want. You can mix, say 1tb and 2tb drives. What other ways can I do this without UnRAID? Its limitation is that you cant do anything else and I would want to run other things like apache, mysql, etc. -Jason

Inquery: popular upload tools for customer codes in use

Hi all, I've had a project to upload customer codes and some data to members inside a webfarm, the upload work will be done almost daily for quite a while. Customer needs the upload status be confirmed everytime and data will be verified later easily when in need. Is there one or more popular tools available for this purposes? open source is preferred, but commercial ones are fine too as long as price is aceeptable. Thanks. --Robinson
