GNBD and DRBD kernel mods
by Bart 18 Aug '07

18 Aug '07

Hi all, I am using heartbeat and drbd on CentOS 5 (see http://www.centos.org/modules/newbb/viewtopic.php?topic_id=7816&forum=41 for details).. DRBD and heartbeat are working, and now I want to put GNBD on top on this. However, I installed the latest CentOS-plus kernel (2.6.18-8.1.8.el5.centos.plus) but there doesn't appear to be a kmod-gndb for this kernel. Looks like the latest kmod-gnbd is available for kernel 2.6.18-8.1.8.el5. But I cannot find a kmod-drbd for this kernel. Am I missing something or is this worth a entry in the buglist?

repost: SELinux questions, upon restarting BIND
by Ray Leventhal 18 Aug '07

As this remains an issue for me, I'm reposting. Please forgive the redundancy, but I've been unable to find the answer and am hoping for some guidance.

Problem is, I'm still not sure what should be done. I'd rather not disable SELinux protection by doing this: setsebool -P named_disable_trans=1 ...but the instructions for alerting SELinux to the chrooted file locations are a bit short of my (inexperienced) needs. Any help would be greatly appreciated. @Moderator: if this is truly off-topic, my apologies. Please let me know and I will post to an SELinux list.

CPU and FBDIMM thermal monitoring
by Bernd Bartmann 17 Aug '07

17 Aug '07

I'm running Centos5 x86_64 on an ASUS DSBV-DX/SAS mainboard with a Xeon E5345 quad core CPU. The mainboard BIOS shows me all the thermal information about CPU and the FBDIMMs as well as the fan rotation speeds. ACPI is set to version 3.0 in the BIOS. Under Centos5 I can't see any of these information under /proc/acpi/thermal_zone. This directory is just empty. Do I have to load any special kernel modules to get the correct values? Of course I'd like to have acpid give alerts or shut down the system in case of overheating. Best regards, Bernd.

Help in starting spamassassin
by Robert Moskowitz 17 Aug '07

17 Aug '07

I have installed spamassassin, per the instructions on Scalix's wiki, and it is working, with some important caviats. So I asked for help on the spamassassin user list, and got some, but I think I am butting up against some Centos specific issues... This is what I am seeing in the maillog: Aug 17 14:39:59 z9m9z sendmail[13082]: l7HIdvGf013082: Milter add: header: X-Spam-Checker-Version: SpamAssassin 3.1.9 (2007-02-13) on\n\tz9m9z.htt-consult.com Aug 17 14:39:59 z9m9z spamd[13032]: spamd: connection from localhost.localdomain [127.0.0.1] at port 40454 Aug 17 14:39:59 z9m9z spamd[13032]: spamd: setuid to root succeeded Aug 17 14:39:59 z9m9z spamd[13032]: spamd: still running as root: user not specified with -u, not found, or set to root, falling back to nobody at /usr/bin/spamd line 1161, <GEN10> line 4.

To create a user: spamfilter. and add -u spamfilter to the start command. So I created the user and group. I ran the spamassassin --lint and -D --lint Then I went to /etc/rc.d/init.d/spamassassin and change the lines: # Set default spamd configuration. SPAMDOPTIONS="-d -c -m5 -H" SPAMD_PID=/var/run/spamd.pid to # Set default spamd configuration. SPAMDOPTIONS="-u spamfilter -d -c -m5 -H" SPAMD_PID=/var/run/spamd.pid And then did: /etc/rc.d/init.d/spamassassin restart and spamassassin is still running as root and I am still getting these errors....

I'm trying to find the cause of why my system froze or crashed. The only recent change ( a few weeks ago ) that I did was an upgrade of ossec from 1.2 to 1.3. Does this log show or hint to the cause of the problem? Thank You Noel

Install CentOS from a floppy disk
by Mário Gamito 17 Aug '07

17 Aug '07

Hi, I'm trying to install CentOS 4.5 in a PIII. Problem is the computer doesn't boot by the CD-ROM drive and when I try to access the BIOS to change the settings, the machine goes bezerk :( Is it possible to start the install through a floppy and then continue the rest of the install process with the CDs ? If so, how ? Any help would be appreciated. Warm regards, -- :wq! Mário Gamito

mod_gnutls and named based virtual hosts on HTTPS
by Johnny Hughes 17 Aug '07

17 Aug '07

All, For anyone interested, there is an rpm in the CentOS testing repository for mod_gnutls for CentOS 5. It allows named based virtual hosting for HTTPS (Single IP, multiple sites and certificates). The idea to build the RPMS came from this article: http://www.g-loaded.eu/2007/08/10/ssl-enabled-name-based-apache-virtual-hos… Here is a guide for installing and using the new RPMS on CentOS 5: http://www.hughesjr.com/content/view/20/1/ RPMS uploaded are: http://dev.centos.org/centos/5/testing/i386/RPMS/mod_gnutls-0.2.0-1.el5.cen… http://dev.centos.org/centos/5/testing/x86_64/RPMS/mod_gnutls-0.2.0-1.el5.c… http://dev.centos.org/centos/5/testing/SRPMS/mod_gnutls-0.2.0-1.el5.centos.… Thanks, Johnny Hughes

logrotate and httpd logs
by Scott Moseman 17 Aug '07

17 Aug '07

I swear that I've removed httpd from logrotate.d on more than one occasion because I prefer to rotate httpd logs on my own schedule. But the config keeps on returning and throwing off my stats. I'm assuming that when there is an Apache upgrade that it's re-inserting the config into the logrotate.d directory? Is there an easy way to stop it from doing this? I *really* do not want to have to manually remove the config each time I upgrade Apache... Thanks, Scott
