Folding@Home + CentOS 4.3 = success
by Chris Mauritz 22 May '06

22 May '06

The Folding@Home client seems to be a wonderful stressor of the CentOS server systems I've been burning in. I've been running two copies of the client on physical dual-core and single die dual-core machines for a few days now. Nary a whimper from the machines and only a slight elevation in temperature (they're 1RU rackmount systems with aggressive/loud fans). In contrast, I loaded the client on a few Win2K (server and workstation) and my WinXP laptop and every single one of them eventually bombed out the client (though without crashing the machines). All were running the 5.04beta client. So I guess it's time to deploy these puppies. (Darn, just when I was poised to break into the top 10 on the CentOS team...heh) Cheers,

CentOS 4 and SATA RAID
by Kai Schaetzl 22 May '06

22 May '06

There have been several threads about SATA in the past weeks and the problems with it. I'm still not clear, though, if SATA in general is a problem or just specific functionality or hardware. Do I understand correctly that "mainboard built-in" SATA RAID is a nono on CentOS? That I would need a third-party RAID card for this? What about SATA non-RAID or SATA2? Is SATA supposed to work in general or do the disks need to run in IDE mode? Do I generally need drivers from the hardware (mainboard, chipset) vendor or is "normal" SATA supposed to work with the packaged drivers? Kai

LiveCD different sums but file size match
by Alain Reguera 21 May '06

21 May '06

Hello, I just downloaded the very great CentOS LiveCD and have some issue with the sum. when I do md5sum -c md5sum.livecd they simply don't match. But when check the size file with the file size posted by johnny in the announce http://lists.centos.org/pipermail/centos-announce/2006-May/012905.html They both match (in 717729792 bytes) Probably I am doing something wrong, just to be sure before burn it. I used the url: http://styx.biochem.wfubmc.edu/mirror/CentOS/4.3/isos/i386/ Regards, --alain

Centos 3.6 - iscsi target issues
by Bruno Sousa 21 May '06

21 May '06

Hello, I'm running a server that needs to have a kernel 2.4.xxx. So now I'm running a CentOS 3.6 with kernel 2.4.21-37.0.1.ELsmp. Now, I want to make this server usable for ISCSI, so I started to install the ISCSI target, and the problems begin. If I try to install ISCSI version 0.4.13 from source code I got the following error : The present kernel configuration has modules disabled. Type 'make config' and enable loadable module support. Then build a kernel with module support enabled. This means that the CentOS kernel doesn't allow to insert modules? Sorry for perhaps being a lame question, but I can , and use, insmod all the time. Anyway, later on I found a src.rpm, so I give it a try. The file is http://www.digicola.com/developer/iscsitarget-0.4.12-6.src.rpm , and i i try to rebuild the rpm , with the command rpmbuild --rebuild iscsitarget-0.4.12-6.src.rpm it gives me the following error : error: Failed build dependencies: kernel-smp-devel = 2.4.21-37.0.1.EL is needed by iscsitarget-0.4.12-6 I searched a little and I installed the kernel-devel package.but it still doesn't work. If anyone could point me out some way to solve this, it would be very appreciated. Best regards, Bruno Sousa

sendmail config problem
by Paul R. Ganci 21 May '06

21 May '06

Recently my wife received an Email addressed from jdavidson4(a)home.com. When she tried to reply to the original message her reply bounced with ----- The following addresses had permanent fatal errors ----- <jdavidson4(a)home.com> (reason: 553 5.3.5 system config error) ----- Transcript of session follows ----- 553 5.3.5 home.com.nurdog.com. config error: mail loops back to me (MX problem?) 554 5.3.5 Local configuration error I started to do some digging and discovered that there is no MX record for home.com which is the ultimate reason my wife's message bounces. However what disturbs me is that given the lack of DNS MX record for home.com my Email server is tacking my domain name nurdog.com onto the original domain name and creating home.com.nurdog.com. I verified that this action is indeed occurring: # sendmail -bt -C./sendmail.cf ADDRESS TEST MODE (ruleset 3 NOT automatically invoked) Enter <ruleset> <address> > 3,0 jdavidson4(a)home.com canonify input: jdavidson4 @ home . com Canonify2 input: jdavidson4 < @ home . com > Canonify2 returns: jdavidson4 < @ home . com . nurdog . com . > canonify returns: jdavidson4 < @ home . com . nurdog . com . > parse input: jdavidson4 < @ home . com . nurdog . com . > Parse0 input: jdavidson4 < @ home . com . nurdog . com . > Parse0 returns: jdavidson4 < @ home . com . nurdog . com . > ParseLocal input: jdavidson4 < @ home . com . nurdog . com . > ParseLocal returns: jdavidson4 < @ home . com . nurdog . com . > Parse1 input: jdavidson4 < @ home . com . nurdog . com . > Mailertable input: < home . com . nurdog . com > jdavidson4 < @ home . com . nurdog . com . > Mailertable input: home . < com . nurdog . com > jdavidson4 < @ home . com . nurdog . com . > Mailertable input: home . com . < nurdog . com > jdavidson4 < @ home . com . nurdog . com . > Mailertable input: home . com . nurdog . < com > jdavidson4 < @ home . com . nurdog . com . > Mailertable returns: jdavidson4 < @ home . com . nurdog . com . > Mailertable returns: jdavidson4 < @ home . com . nurdog . com . > Mailertable returns: jdavidson4 < @ home . com . nurdog . com . > Mailertable returns: jdavidson4 < @ home . com . nurdog . com . > MailerToTriple input: < > jdavidson4 < @ home . com . nurdog . com . > MailerToTriple returns: jdavidson4 < @ home . com . nurdog . com . > Parse1 returns: $# esmtp $@ home . com . nurdog . com . $: jdavidson4 < @ home . com . nurdog . com . > parse returns: $# esmtp $@ home . com . nurdog . com . $: jdavidson4 < @ home . com . nurdog . com . > I run a second server that does not have this problem and this issue only seems to occur on domains with broken DNS.

I am not that concerned about this problem, but for the life of me googling and comparing the config files between my two Email servers does not indicate anthing obvious to me to cause this behavior. Does anyone have an idea to which sendmail config parameter might be causing nurdog.com to get tacked onto home.com in these circumstances? Thanks for any ideas. -- Paul (ganci(a)nurdog.com)

mysql : Access denied for user
by kenkensmile＠netscape.net 20 May '06

20 May '06

Hi all, I am having a problem with mysql. I set up root password set password for root@localhost=password('xxxxxxxxx'); set password for root@'xxx.yyyy.com'=password('yyyyyyyy'); after that I tried to log in, but mysql says ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) I guess that I had the right password. My friend told me that I might have used a wrong password, so I set up new password for root. However, mysql says the exactly same thing!! ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) I was not sure about the error, so I decided to remove mysql and deleted /var/lib/mysql. After that I reinstalled mysql and set up mysql again. However, mysql again says ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) I am 100000% sure that I am using the right passward for root I am quite puzzled by the error and need your help. Does anyone know how I can fix this problem? I am using CentOS4.3. Thank you for your help. Cheers, Joe ___________________________________________________ Try the New Netscape Mail Today!

Centos 4.3 and Card Reader
by Ralph Alvy 20 May '06

20 May '06

CentOS 4.3 (fully updated, including CentOS Plus kernel). Running KDE 3.5.2 (fully updated from redhat.kde repo). I can't seem to get the OS to recognize my SD card when inserted into my USB card reader. Mepis 6 Beta 3 has no problem with it. DMESG sees nothing happening when the card is inserted. USB-STORAGE module is loaded.
