Wherefore whitebox?
by Benjamin Smith 18 Oct '05

18 Oct '05

Well, I'm a recent convert from WBEL. My biggest concern with CentOS is that the community here seems to want to be more than a recompile of RHEL. But WBEL is floundering, what with Katrina and Rita, and there really being only 1 developer behind it, etc. I offer an automated shell script to switch from WBEL4 to CentOS4 (easy, it's hosted on my home DSL line!) It assumes that you've been using yum to perform updates... http://chico.benjamindsmith.com/wbel2centos4.sh How many otther ex-WBEL users are there here? -Ben -- "The best way to predict the future is to invent it." - XEROX PARC slogan, circa 1978

CentOS-4.1 (Final) on Dell Inspiron 9300 Laptop
by Turker Dundar 18 Oct '05

18 Oct '05

Hi, I have been using CenOS-4.1 quite sometime now on this laptop. Under CentOS I am having a problem during boots (soft or hard boots) that I never had with any other Linux distros including Fedora 4. I have to reboot the laptop twice as the first boot returns blank screen and hangs when it attempts to bring up login screen. I tested this a few times, there is no disk activity or any sign of OS activity.. In the end I switch the laptop off and start again.. It works fine perfectly in the second boot. Not sure what happens in the first boot (though all startup processes return OK till it gets hung) How can I diagnose this problem..? Is this a known problem..? Is there any workarounds..etc ? Thanks, Turker -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Radio software
by Sam Drinkard 18 Oct '05

18 Oct '05

Hi List, Does anyone know of any type of radio tuner software available for CentOS in either 32 or 64-bit versions? The card is an ATI X600. I've got the video driver from ATI installed, but they do not have any other user level software available. I think I remember reading something about some software being available for the BT chipset, but I'm a tad out of date on that. Also, while in my thoughts, who is the individual responsible for the screensaver(s) creation? I have a fantastic idea I'd love to pass to whoever does the coding. Thanks, -- Snowman

I can't find 'system-config-authentication' anywhere in the centos repos. I know its part of upstream... but we don't seem to have it. Am I missing something? -jim

RE: [CentOS] Missing In PATH

Maybe try a 'su -' instead of 'su'? -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Cody Holland Sent: Monday, October 17, 2005 4:08 PM To: centos(a)centos.org Subject: [CentOS] Missing In PATH I'm a newb to linux so please be patient. Running CentOS 4. Using Bash. I'm not sure what happened, but now for some reason /sbin, /usr/sbin, and /usr/local/sbin are all missing from the path. I am su'd as root. I've tried several different methods to put this back including: PATH="/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/hom e/cholland/bin:/sbin:/usr/sbin:/usr/local/sbin" export PATH=$PATH:/sbin export PATH=$PATH:/usr/sbin export PATH=$PATH:/usr/local/sbin All of these do add the directories to the path until I logout and log back in. Then they are gone again. Any help would be greatly appreciated.

Update or not?
by Sam Drinkard 17 Oct '05

17 Oct '05

After reading all the problems with the x86-64 update, I'm in a quandry as to update this machine or not. Nothing that I am aware of is broken, and at least everything I use works. This is NOT a production machine, but it does have some important software that needs to run twice daily, and I sure don't want to break things for that. If upgrade is not necessary, how do I go about turning off that red exclaimation point on the upper menu bar? Just tell it to ignore everything? -- Snowman

Kernel Audit Messages
by Kirk Bocek 17 Oct '05

17 Oct '05

Since updating to 4.2 my Opteron server has been flooded by messages like: audit(1129565701.837:155): user pid=4700 uid=0 auid=4294967295 msg='PAM session open: user=root exe="/usr/sbin/crond" (hostname=?, addr=?, terminal=cron result=Success)' to both /var/log/messages and the kernel ring buffer. Looks like they are being generated by cron jobs being run on the server. Does anyone know how to turn these messages off or to redirect them? Kirk

I have rpms for tomcat that install ok, but then the services give a ton of errors about missing files when you start/stop them Failing this can anyone recommend any free Networm Management System for Centos, I only need a simple solution just so that I can import mibs into it and send it traps! OpenNMS seemed a good choice as it does everything (although rather too heavyweight for what I want), as its taken me and a few Java experts here more than two days to try and install OpenNMS I think its time to move onto something else. Any advice is most welcome! Regards Pete _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

Centos 4.1 Boot Problem on ML570 with Compag 5300 Storage Array Raid Controller
by Dave Augustus 17 Oct '05

17 Oct '05

Hello All, Hardware: HP ML570 2G Ram Dual 2.8G procs Compaq 5300 Smart Array Controller Software: Centos 4.1 I yum-med a server last week and rebooted it. When it came up, it stopped. Looking at the console, I got: ---snip Setting Hostname: OK Checking root filesystem: /dev/cciss/c0d0p10 is mounted, e2fsck cannot continue, aborting failed *** an error occurred during the file system check *** Dropping you to a shell; The system will reboot *** when you leave the shell Give root password for maintenance (or type Control-D to continue) ---snip So I did what any good sysadmin would do- I grabbed the boot disk and rebooted the box in rescue mode and ran e2fsck on the /root partition. No errors came up and rebooting the box resulted in the same error! So I dug a little, and found that putting some comments in /etc/rc.d/rc.sysinit would circumvent *the error* and allow the box to boot. Here are the lines - (around line 375) if [ "${RHGB_STARTED}" != "0" -a -w /etc/rhgb/temp/rhgb-console ]; then fsck -T -a $rootdev $fsckoptions > /etc/rhgb/temp/rhgb-console else initlog -c "fsck -T -a $rootdev $fsckoptions" fi Here are the grub.conf boot settings: title CentOS (2.6.9-22.ELsmp) root (hd0,0) kernel /vmlinuz-2.6.9-22.ELsmp ro root=LABEL=/ rhgb quiet initrd /initrd-2.6.9-22.ELsmp.img My question is: WHAT IS THE ERROR? TIA, Dave Augustus
