/usr/bin/id behavior since CentOS 5.2 upgrade
by kfx 25 Jun '08

25 Jun '08

Hi list, Since the upgrade to 5.2, when I log into my server with a ldap account I have these 2 errors messages: -bash: [: =: unary operator expected -bash: [: -le: unary operator expected After investigation, the trouble come from two scripts in /etc/profile.d: /etc/profile.d/krb5-workstation.sh /etc/profile.d/vim.sh The problem is with the test where the command "id" is involved, like: if [ `/usr/bin/id -u` = 0 ] ; If I add double quotes ("`/usr/bin/id -u`"), it will work again. Indeed, as a connected ldap user, the id command returns nothing when quoted: [ldapUser@server ~]$ /usr/bin/id -u 12345 [ldapUser@server ~]$ `/usr/bin/id -u` [ldapUser@server ~]$ As a normal user, the command behaves normally: [user@server ~]$ `/usr/bin/id -u` -bash: 1302: command not found [user@server ~]$ /usr/bin/id -u 1302 I have modified theses two scripts but I am afraid it will break something in the future. Any idea on how to resolve this cleanly ? Best regards, kfx PS: Linux server 2.6.18-92.1.1.el5xen #1 SMP Sat Jun 21 19:21:20 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

udevd can't reach LDAP-server during boot
by Bernhard Gschaider 25 Jun '08

25 Jun '08

Hi! I'm using CentOS 5.1 (x86_64) machines which authenticate using LDAP. At the start of booting I get messages like this: udevd[1158]: nss_ldap: failed to bind to LDAP server ldaps://ldap.server.example.com/: Can't contact LDAP server udevd[1158]: nss_ldap: reconnecting to LDAP server... udevd[1158]: nss_ldap: could not connect to any LDAP server as (null) - Can't contact LDAP server udevd[1158]: nss_ldap: failed to bind to LDAP server ldaps://ldap.server.example.com/: Can't contact LDAP server udevd[1158]: nss_ldap: reconnecting to LDAP server (sleeping 1 seconds)... This escaletes to 2, 4, 8, 16, 32, 64 seconds. After that (==timeouting for 2 minutes) booting continues without problem, so this is not really a showstopper, but inconvenient. Googling around revealed some fixes for Debian/Ubuntu. The bottom line i that udevd needs some user/group that is not in the local files but on the LDAP-server. The fix usually was adding this user (nvram, scanner ...) or group locally. The problem is, that on these systems after the last attempt something like udevd[1158]: lookup_group: error resolving group 'rdma': Illegal seek is printed out, makeing it easy to find the right group/user. Is there a way to get CentOS to a similar behaviour, making it easier to find the culprit? Bernhard

Kernel panic since CentOS 5.2 upgrade

Hello, since upgrading to CentOS 5.2 my notebook hangs while booting with a "Kernel panic - not syncing: Fatal exception" error. Here is a screenshot: http://www.istari.de/olaf/centos/r0013878.jpg # uname -a Linux beutelsend.istari.de 2.6.18-53.1.21.el5 #1 SMP Tue May 20 09:34:18 EDT 2008 i686 i686 i386 GNU/Linux # grep kernel /etc/grub.conf kernel /vmlinuz-2.6.18-92.1.1.el5 ro root=/dev/VolGroup00/LogVol00 acpi=off noapic apm=power-off # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 5 model name : Pentium II (Deschutes) stepping : 2 cpu MHz : 266.637 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 mtrr pge mca cmov pat pse36 mmx fxsr up bogomips : 533.80 Ok, that toshiba tecra 8000 notebook is very old, but I use it as a thin client.

Suggestions for a plug and play CA certificate manager?
by James B. Byrne 24 Jun '08

24 Jun '08

I have played with self-signed end-use PKI certificates for about a decade now and would really like to set up a proper, albeit private, PKI using some sort of OFS CA management software. I have looked at OpenCA and found a few packages on sourceforge but they all seem to fall short of my desires in one form or another (rpm install, multiple subordinate CAs, certificate revocation and extension management, web-based or linux/microsoft GUI) . I have even tried to use the scripts that come with OpenSSL with very limited success. What I would like to do is to set up a self-signed root CA certificate, then use that to issue one or more signing CA's, each possibly limited as to what type of certificate that they can sign. These issuing CAs would then sign certificate requests for end-use certificates for hosts, email accounts, document provenance, objects, etc. | -- root_CA | | -- issuer_hosts_a_CA | | -- certs | | | -- cert_issued_index | | ` -- cert_revoked_list | | -- csrs | ` -- private | ` -- issuer_hosts_a_CA+key.pem | | -- issuer_services_a_CA | | -- certs | | | -- cert_issued_index | | ` -- cert_revoked_list | | -- csrs | ` -- private | ` -- issuer_services_a_CA+key.pem | ` -- issuer_email_a_CA | -- certs | | -- cert_issued_index | ` -- cert_revoked_list | -- csrs ` -- private ` -- issuer_email_a_CA+key.pem What software do people use to manage a PKI on CentOS5?

rsh issue/update (access denied)...

hi... i've got an "access denied" issue with rsh on one of my boxes (and before we start, no "use ssh" comments.. rsh is what i'm dealing with for now!!) i've got a few boxes in my network, and i can successfully rsh into them with no issue. however, on one box, i can't access it using rsh, and i'm running out of things to try... kind of curious. i can login using rlogin. i've modifed the /etc/pam.d/rsh,rlogin files, along with the /etc/securetty file. i've also changed the /etc/xinetd.d/(rsh,rlogin)files. as far as i can tell, nothing else has been changed... the curious thing. as far as i can tell... the files on the system that doesn't work, are the same as the files on the systems that are allowing rsh to occur... the err i'm getting in the /var/log/secure is: Jun 23 22:16:09 lserver5 userhelper[2186]: pam_timestamp(system-config-services:session): updated timestamp file `/var/run/sudo/root/unknown' Jun 23 22:16:09 lserver5 userhelper[2189]: running '/usr/sbin/system-config-services' with root privileges on behalf of 'root' Jun 23 22:16:28 lserver5 xinetd[2227]: START: shell pid=2239 from=192.168.1.45 Jun 23 22:16:28 lserver5 rshd[2239]: pam_rhosts_auth(rsh:auth): denied to root(a)192.168.1.45 as test1: access not allowed Jun 23 22:16:28 lserver5 rshd[2239]: pam_unix(rsh:session): session opened for user test1 by (uid=0) Jun 23 22:16:28 lserver5 rshd[2239]: pam_unix(rsh:session): session closed for user test1 etc/pam.d/rsh #%PAM-1.0 # For root login to succeed here with pam_securetty, "rsh" must be # listed in /etc/securetty. auth required pam_nologin.so auth sufficient pam_rhosts_auth.so promiscuous auth required pam_securetty.so auth required pam_env.so account include system-auth session include system-auth etc/pam.d/rlogin #%PAM-1.0 # For root login to succeed here with pam_securetty, "rlogin" must be # listed in /etc/securetty. auth required pam_nologin.so auth sufficient pam_rhosts_auth.so promiscuous auth required pam_securetty.so auth required pam_env.so auth include system-auth account include system-auth password include system-auth session include system-auth /etc/securetty rsh rlogin rlogind rexec console vc/1 vc/2 vc/3 vc/4 vc/5 . . . /etc/xinetd.d/rexec:: # description: Rexecd is the server for the rexec(3) routine.

CentOS 5 based distribution
by A.B. 24 Jun '08

24 Jun '08

I've been trying to create a Linux distribution based on CentOS 5, similar to (actually, exactly like) how CentOS is based on RHEL. I have been unable to find any information about this. Most of what I find are tutorials and instructions on using Kickstart. Sometimes I've found allusions to doing this, but nothing that gives all the instructions necessary to modify Anaconda (or other files) sufficiently. I have found an excellent walkthrough ( http://wings.buffalo.edu/computing/ublinux/) on creating a distribution based on RHEL 4. While following the instructions I have found that not everything is in exactly the same place when using CentOS 5, but the descriptions are close enough that I have been able to figure it out and create a mostly "rebranded" install DVD. One thing that the above walkthrough does not explain is how to change all the text and images (it points to most of the images) and the default "packages". By that I mean the screen where the installer asks what additional tasks I would like the system to include support for: i.e. Desktop - Gnome, Server, Server - GUI, etc... I have been unable to find where this information, and some of the other text the installer uses (for example, "Searching for CentOS installations"), is stored. I've greped the entire DVD (including the expanded stage2.img file), but cannot find this text anywhere. Is the information stored in a compiled executable? If so, which executable will I need to recompile? Thanks.

recommendations for copying large filesystems

I did a yum update last night at about 23h15 EDT (-4). No upgrade. I just did a yum update this morning at about 08h45 (-4). for my system there's about 348 megs of updates. Now all I have to do is figure out how to remove OO.o 2.0.whatever which is being upgraded to 2.3.whatever. I'm using 2.4.1 on my 4.6 boxes (have always been using the latest OO.o on them since installation a couple of years ago.) Any ideas on how to completely remove the OO.o references for Yum, after having tried to do rpm -Uvh *.rpm, after trying again and doing a yum cleanup, etc. etc.?

I have recently moved from Trac to Redmine for project management (and I strongly recommend that you consider this as an alternative to Trac, it is far more powerful to use and much easier to set up) but I had/have exactly the same problems that you are facing. The difficulty is that Trac has a DBMS backend, usually MySQl but in my case PostgreSQl. This complicates the issue since it is not enough to simply tar up the application site. What I ended up doing was building a hot site spare server to accommodate all of these types of applications (Trac project management, subversion repositories, drupal user cms sites, imapd user mailboxes, avantfax fax archives). Then, for applications that employed a database backend, I setup regular cron jobs to dump the backend databases into a ./dbdump directory that I added to the root of each site's file system. I added an rsync command to the end of the dump command to then move the entire site to the backup box at the end of the dump. On the backup machine I added a cron job to reload the database from the dump. This entails some background work to set up. You must initialize and configure the appropriate DBMS on the backup server with the requisite databases and database owners. You must ensure that the application's users and groups are properly replicated there. You may need to install and configure the application itself. You may need to configure apache if the application uses a web frontend, like Trac. You need to setup SSL host to host root authentication for rsync. And there are no doubt several other little things that need to be accommodated but that I no doubt have forgotten. However, what this gives you is a hot site backup that a simple change to DNS can enable. -- *** E-Mail is NOT a SECURE channel *** James B.

SME on CentOS, telnet and MySQL
by Michael 24 Jun '08

24 Jun '08

After failing to install on two different machines that were running Windows, I realized that one machine had a bad hard-drive, and the other bad memory. So I've collected the good parts into one machine and installed CentOS with SME. This was the fastest install of Linux I have every seen, 15 minutes done, configured, and running, web and email server. It is a very secure config, no GUI -- just a server. One problem: MySQL and Telnet can't be accessed remotely, ports not open, allow/deny files, something. I've searched the internet and hacked around for hours, can't get these services to work remotely. Anyone here have experience with the SME/e-smith admin tools? By default SME doesn't install Telnet on port 23, only ssh on port 22. So I ran a yum install for telnet, manually started it. I get a response from port 23, but connection refused. Mysql does come installed with SME, however local connections only. I can run mysql client on the command line on the SME.CentOS server, queries work fine, but not remotely. I am using Windows Vista as a client workstation, Programmer Studio (Whisper Technology) that requires a generic telnet server, and the freeware version of Toad to connect to the MySQL server. Any help to weaken the security on SME to allow remote telnet and MySQL connections will be very much appreciated! -- Michael Anderson, J3k Solutions Sr.Systems Programmer/Analyst 832.515.3868

Upgrading my local repo to 5.2
by Robert Moskowitz 24 Jun '08

24 Jun '08

This will be the first version change with my local repo so I want to check the steps out. I have a /Centos/5.1 directory with all the contents of the ISO CDs. I have a /Centos/5 directory with a symbolic link to the 5.1 directory. I ASSUME that I will create a /Centos/5.2 directory and drop the contents of the ISO images there. Then change the symbolic link to the 5.2 directory. After I test out both installs and upgrades from this new directory I can trash the old 5.1 directory. Do I have it right?

Why CentOS 5.2 is so large?
by Michael Liang 24 Jun '08

24 Jun '08

Hi, folks. I have download the DVD image of CentOS 5.2. Comparing with the DVD image of Upstream OS Provider, I got a surprise: The size of the DVD image of Upstream OS Provider is just 2.87 GB(i386), but the size of the DVD image of CentOS 5.2(i386) is so large that is 3.74 GB! I kown that CentOS's developers did very excellent work on how to make the Upstream OS more availability and add many good free software on the CentOS. But where can I got the change or add list of CentOS? and why the size change is so large? I think it is very useful for my farther employ of CentOS. Thanks! (Yes, I can read the ReleaseNotes, but it is still can not disabuse me, the secsion of "5.6. Packages added by CentOS that are not included upstream" is so little.)

backup question
by Gergely Buday 24 Jun '08

24 Jun '08

Dear CentOs users, I have a centos server with nothing important at the moment, but I would like to install some web-based project management tool (trac for the curious) that would contain important data. And, as my network is growing the configuration of the server is becoming complex. I would like to have a proper backup so that I can restore the whole system easily, should any problem occur. What do you recommend? I'm not an expert on this, so my first idea is that I could do a per application backup and create a tar file of the /etc. The latter especially could be too naive. And, a push-the-button method that handles all in once, not depending on the app number would be much better. Another thing: how I could do this to be safe across a centos upgrade? - Gergely

Network FS w/o user setup
by Ted Miller 24 Jun '08

24 Jun '08

Is there a file system + configuration that will let me share a directory, and anyone who has access to something in that directory on the server will also have access (and lack of access) to the same files from the client? Clients will be Centos5, Win2K, WinXP. Server is Centos5. To put it another way, all users have accounts on the server. I don't want to have to set up ANY user information on the server, other than what I set up to control local access. I just want to say "Share /vmware" and have it available, to the same users who can access it locally. With Samba I have to maintain duplicate user lists, password lists, and share access lists. I have not been able to find a clear instructions on how NFS4 handles this, but what I found didn't seem any better than Samba. I don't mind implementing ACLs on the server if it will do what I need, but I can't find anything that says it will save me any work either. Looking for a better way, Ted Miller Indiana, USA

Hi - daft one for Friday morning coffee break: I have been trying to mount floppies on a couple of CentOS5 servers - the usual "mount /dev/fd0 /mnt/floppy" (yes, /mnt/floppy exists!). On both servers, the mount command just doesn't come back and I have to hit CTRL-C. I have tried different media and also changed the floppy drive on one server, /dev/fd0 is seen as present on both servers and they are enabled in the BIOS. I have formatted and tested the floppies on my desktop PC without problems. In the end, I gave up, stuck a USB floppy on one of the boxes and it mounted with no problems. So is it me, CentOS 5 or something else? (Ideas, anyone!?). It could be a set of duff floppies and three flaky drives (two brand new), but I thought I'd ask before I spend too much more time on it! Thanks Nigel Kendrick

Awk help
by Joseph L. Casale 23 Jun '08

23 Jun '08

I have csvde dump from active directory I process on my postfix mta. It takes output like this: "CN=Curtis xxx,OU=Domain Users,OU=xxx xxx,DC=xxx-xxx,DC=local",X400:c=US\;a= \;p=xxx xxx xxx\;o=Exchange\;s=xxx\;g=xxx\;;SMTP:Cxxx@xxx-xxx.com and should return a relay_recipient map in the form of: Cxxx(a)xxx-xxx.com OK The command I am using is: cat $1 | tr -d \" | tr , \\n| tr \; \\n | awk -F\: '/(SMTP|smtp):/ {printf("%s\tOK\n",$2)}' Everything up to the awk is working, it drops the smtp: but its putting OK's all over the darn place. Anyone familiar enough with awk and printf that can suggest why this happens? Thanks! jlc

CentOS tools for public safety
by Rogelio 23 Jun '08

23 Jun '08

A friend of mine from the CentOS community is extremely close to several northern CA fires. http://tinyurl.com/5vp933 http://tinyurl.com/3mk4ah http://tinyurl.com/4jm67 Once things die down (he was evacuated last week), he and I are planning on investigating various CentOS / nix public safety tools for future events like this. Any suggestions in this area would be greatly appreciate. I just recently found out at Sahana, and if there is anything else along those lines, I'd be very grateful.

3ware 9650 issues
by Joshua Baker-LePain 23 Jun '08

23 Jun '08

I've been having no end of issues with a 3ware 9650SE-24M8 in a server that's coming on a year old. I've got 24 WDC WD5001ABYS drives (500GB) hooked to it, running as a single RAID6 w/ a hot spare. These issues boil down to the card periodically throwing errors like the following: sd 1:0:0:0: WARNING: (0x06:0x002C): Command (0x8a) timed out, resetting card. Usually when this happens, it's followed by: 3w-9xxx: scsi1: AEN: INFO (0x04:0x005E): Cache synchronization completed:unit=0. On the less pleasant occasions, it's followed by: scsi1: ERROR: (0x06:0x0036): Response queue (large) empty failed during reset sequence. 3w-9xxx: scsi1: ERROR: (0x06:0x002B): Controller reset failed during scsi host reset. sd 1:0:0:0: scsi: Device offlined - not ready after error recovery This of course leads to a several hour downtime as the system has to be powered down (not just rebooted) and then the volume needs to be fscked. I've been back and forth with both the vendor and (via the vendor) 3ware with this. The card has been replaced, as well as the whole system. I'm running the latest firmware and drivers from 3ware. Have other folks had good luck with this card? What sorts of configs are you running? I'm in the position of needing more storage, and I'm a bit gun shy on 3ware at the moment... -- Joshua Baker-LePain QB3 Shared Cluster Sysadmin UCSF

is it possible to login to a switch via RS232 / serial port from the shell?
by Rudi Ahlers 23 Jun '08

23 Jun '08

Hi all I have a problem switch in our data centre, which is connected to a linux server via a serial cable. I know I can / could access the switch from my Windows PC back at the office, using hyperterm, but trying to access it using minicom just doesn't seem to work. I have changed the comms in minincom to use /dev/tty0 & the baud rate to 9600, yet I can't seem to connect with minicom. Does anyone know how to connect to a serial device from the console? -- Kind Regards Rudi Ahlers CEO, SoftDux Office: 087 805-9573 Fax No: 086 609 6128 Cell: 082 554 7532 Web: http://www.SoftDux.com Forum: http://Forum.SoftDux.com Join SA WebHostingTalk today, on http://www.WebHostingTalk.co.za

Migrating from RHEL to Centos
by Hemraj S 23 Jun '08

23 Jun '08

Hi, I m currently running my production servers on RHEL 4.6 & would like to migrate to Centos4.6 as it has more benefits & advantages. I looked at the Centos release notes available at http://mirror.centos.org/centos/4.6/os/i386/RELEASE-NOTES-en.html and understood that the basic difference between RHEL & Centos are look/feel related & binaries,functionalities are almost same. But when i compared the sysctl values of RHEL4.6 with Centos4.6, i found that there are lot of differences in the parameter values. Now my question is: 1) Just like sysctl difference, is there any other difference between RHEL & Centos which could vary the performance & needs to be taken care during migration. 2) When the Centos packages are built, are they built with the same configuration as in RHEL or is there any difference. Thanks & Regards, Hemraj

cannot unmount volume "xxx"
by 李晖 23 Jun '08

23 Jun '08

Hi all: I am using Centos 5.1. But now I have a problem when unmount a removable usb hard disk with right click and choose unmount volume command. When I did that, system reminds me with a message like this:Cannot unmount volume "xxx", Detail: Cannot remove directory, "xxx" represents a temporary directory made when the system auto mount the disk in /media, and "xxx" is simple-chinese. But in fact, the volume has been removed because there're no files or folder in xxx. Because the file system type of the hard disk is NTFS, Ｉ install ntfs-3g and add a script named "mount.ntfs" in /sbin, the content of the script is #!/bin/sh export LANG=zh_CN.UTF-8 exec /sbin/mount.ntfs-3g "$@" I googled this problem for many days and didn't find any way to solve this problem. Maybe it is a bug. I hope someone can help me. Thank you. -- Sunny Lee

Just looking at the "man rsync". Might as well be duagnosing a plattypus.

(2) Trying to get cron it run 10pm every saturday night. Log whats happening. update packages, include new packages. Exlude extra languages from things like openoffice\xorg etc.. that the family don't need. (family lan) (3) Would one normally download the mirrors "repodata", or run create createrepo oneself?

lvm with iscsi devices on boot
by Raja Subramanian 22 Jun '08

22 Jun '08

Hi All, My CentOS 5.1 server is using iSCSI attached disks connecting to a dual controller storage array. I have also configured multipathd to manage the multiple paths. Everything works well, and on boot the dev nodes are automatically created in /dev/mapper. On these devices, I have created logical volumes using lvm2. My problem is that lvm does not recognize these iscsi/multipath volumes on boot up. I need to manually run "vgchange -ay" and mount the logical volumes by hand. I tried running the vgchange and mount commands from /etc/rc.local, but that has no effect. I have verified that /etc/rc.local itself is executing correctly. What do I need to put in my boot up scripts so logical volumes in iscsi/multipathd devices are automatically recognized on boot? TIA! - Raja

centos 4.6 - 586 install - how to get that to a 486 level if possible

Is there a method to get a 586 (i586 text) install to a 486 level? I am looking for information guidance on this. I have looked into using debian/386 which stinks in my opinion, slackware doesnt quite have it either. So I am wishing/hoping there is a NOT TO painful way to get a 586 install to run on a 486 chip. I have been searching but havent found anything useful. If anyone knows what might need to be done I would appreciate it. Jerry

how do I manage a Dell PE 860 server via IPMI?
by Rudi Ahlers 21 Jun '08

21 Jun '08

Hi all I'm trying to get to grips with this one, but just can't figure it out. I recently acquired some 2nd hand Dell Poweredge 860 servers, and noticed that they have built in remote management interfaces. So, I have setup one, and assigned an IP address to it, but have no idea on how to access it remotely. Google'ing for an answer didn't bring me more than general product information about various different IPMI stuff. So, how do I actually access these servers remotely? If possible, I'd like todo it via another CentOS server at the DC using SSH. tia :) -- Kind Regards Rudi Ahlers CEO, SoftDux Web: http://www.SoftDux.com Check out my technical blog, http://blog.softdux.com for Linux or other technical stuff, or visit http://www.WebHostingTalk.co.za for Web Hosting stuff

Pulling Hair Out - TWiki 4.2 on CentOS 5
by Chuck 21 Jun '08

21 Jun '08

I thought I would turn here before giving up. I am trying to install Twiki 4.2 on CentOS 5 with all updates. (I also tried Twiki 4.1.2 as well) I am running a custom rolled Apache 2.2.8 server and custom rolled PHP 5.2.6 (built with oracle support). These work and are rock solid. I've been using the same config with very heavy duty scripts and php applications with no issues. When trying to run /twiki/bin/configure I get the following error when clicking "Next": Software error: Use of uninitialized value in substitution (s///) at (eval 25) line 23. The Apache error log says pretty much the same thing. (like 23 by the way points to a commented line; the first 100 or so lines in this script are comments.. If I don't count the commented lines there is no search regexp anywhere near line 23) I then tried version 4.1.2 and the same thing. I googled and found numerous other people having this problem. I have found no responses or solutions. The twiki support site has yielded nothing as well. Just hoping someone here might have sorted this out.. I have set up dozens of twiki sites but haven't played with it in a 2 years or so and wondering... It was never this difficult before.. Three of us have now triple checked every file permissions, installation step, system pre-requisite, etc... Thanks for any help, CC

Kernel panic - not syncing: CPU context corrupt
by Alwin Roosen 20 Jun '08

20 Jun '08

Hi, Is there someone on this mailing list who could/want help me figure out this issue? We do not know where to look to solve this. --- Description --- This is a brand new server, which has been tested for days with FreeBSD in our office, and a few days with Windows on the site of our hardware distributor. Now customer wants CentOS, which we installed, but after few days we get a kernel panic. Last night at 2:08 it gave the same kernel panic. Please tell me what information I should give you and most important how to get it from the system, because we do not have experience with CentOS (only FreeBSD). I would be very surprised if this is hardware related. We use the same hardware for several years, and run FreeBSD on it very successfully. It is a SuperMicro PDSMI+ motherboard with 3ware raid controller (8006-2LP). CPU is Xeon 3040 1.8 Ghz EM64 2MB 1066FSB (65W). Memory is DDR 2 Trancend 2048MB ECC Unbuffered 800. Error message on console is in "Additional Information". I am hoping that I should switch off some setting in CentOS to fix this, but I cannot find much useful information about this issue on Google. --- Additional Information --- CentOS release 5 (Final) Kernel 2.6.18-53.1.21.el5 on an i686 ws174 login: CPU 1: Machine Check Exception: 0000000000000005 CPU 0: Machine Check Exception: 0000000000000004 Bank 3: f62000020002010a at 0000000032c93500 Bank 5: f20000300c000e0f Kernel panic - not syncing: CPU context corrupt Bank 3: f62000020002010a --- Attachments --- 19-06-2008 16-03-31.png (Screenshot of console) With kind regards, Alwin Roosen
