CentOS 4 lm_sensors help for intel D945 motherboards
by David Thompson 01 Nov '06

01 Nov '06

Has anyone succeeded in getting lm_sensors to produce useful output for intel D945-based motherboards? According to the lm_sensors site, I need a newer kernel (2.6.16) to read the ICH7 data. I noticed the i2c patches in the kernel source rpm, but no joy. I'd be okay with building my own modules, but haven't found anyone to provide the kernel module source apart from the kernel tree. Am I outta luck here? Thanks in advance. Dave Thompson UW-Madison

yum "transaction check error"
by Bill Comisky 01 Nov '06

01 Nov '06

I need help resolving a "transaction check error" when trying to 'yum install gtk2-devel' on a CentOS 4.2 x86_64 system. I have a feeling this is due to having both x86_64 and i386 libs? # yum list installed xorg-x11-libs Installed Packages xorg-x11-libs.x86_64 6.8.2-1.EL.13.20 installed xorg-x11-libs.i386 6.8.2-1.EL.13.20 installed Is there any way around this? Do I need to erase xorg-x11-libs.i386 (and the gobs of packages that depend on it)? Below is full output from yum install command, thanks! # yum install gtk2-devel Setting up Install Process Setting up repositories Reading repository metadata in from local files Parsing package install arguments Resolving Dependencies --> Populating transaction set with selected packages.

CentOS 4.3 on Intel Xeon Core 2 Duo
by Marc Saric 01 Nov '06

01 Nov '06

Dear list, I am planning to buy a new server -because the new Core2 Duo based Xeons (5100 series) are considerably faster in some scenarios than Opteron machines while not beeing more expensive, I would like to hear some real-world experiences from people who have installed CentOS 4.3 or 4.4 on such a setup. Specifically: CPU: 2x Intel Xeon 5100 2GHz Board: Intel S5000 chipset RAID5: 3ware 9550SXU-4LP I have some experience with the 3ware Adapter (new kernel module needed on install) but now nothing about compatibility, extra drivers or other problems related to the relatively new Xeon/S5000 platform and CentOS 4.3/RHEL 4.3. Thanks for any feedback. -- Bye, Marc Saric

glibc free error rebuilding iproute-2.6.9-3.EL4.3.centos4.src.rpm

I'm getting a strange error while rebuilding iproute-2.6.9-3.EL4.3.centos4.src.rpm ... rpmbuild --rebuild iproute-2.6.9-3.EL4.3.centos4.src.rpm ... ./normal >normal.dist *** glibc detected *** free(): invalid next size (normal): 0x08491050 *** /bin/sh: line 1: 5236 Aborted ./normal >normal.dist make[1]: *** [normal.dist] Error 134 ... + install -m 644 tc/normal.dist tc/pareto.dist tc/paretonormal.dist /data/tmp/cd654c/rpm/tmp/iproute-2.6.9-root/usr/lib/tc install: cannot stat `tc/pareto.dist': No such file or directory install: cannot stat `tc/paretonormal.dist': No such file or directory error: Bad exit status from /data/tmp/cd654c/rpm/tmp/rpm-tmp.36741 (%install) ... etc. Any ideas as to what might be causing this heap corruption? I'm using a pretty much stock CentOS 4.3 box to perform the rpm rebuild.

Running two sshd's
by Gilles CHAUVIN 31 Oct '06

31 Oct '06

Hi all, I'm wondering whether it is feasible or not to run two distinct sshd daemons with different config options! I have a CentOS 4.4 gateway with 2 Ethernet interfaces. One is connected to the Internet and the other to the LAN. Basically, what I would like to do is having a sshd that listens to the LAN interface with password enabled auth. and a sshd bound to the Internet interface with forced key auth. (no password auth. allowed). I'm not sure that such a thing is possible using a single sshd_config file. What do you think would be the best way to do this? Is there someone here that already made a similar setup? Thanks for any help / ideas. Regards, Gilles.

mysql won't start
by David Mackintosh 31 Oct '06

31 Oct '06

OK so at some point I borked my mysql 4.1.20 installation on my x86_64 system. Possibly relevant: I have enabled the centosplus repository in yum.conf because I needed a package from there. I have not upgraded mysql from there. Everything was working, then "something" aparrently happened, and now mysql won't start. The logs say: 061031 11:37:38 mysqld started 061031 11:37:38 [ERROR] Can't start server : Bind on unix socket: Permission denied 061031 11:37:38 [ERROR] Do you already have another mysqld server running on socket: /var/lib/mysql/mysql.sock ? 061031 11:37:38 [ERROR] Aborting 061031 11:37:38 [Note] /usr/libexec/mysqld: Shutdown complete Now the naive would presume that there is a permissions problem on /var/lib/mysql/mysql.sock, right? Certainly the web suggests that this is the problem. [root@urquell2 ~]# ls -ld /var/lib/mysql/mysql.sock /var/lib/mysql ls: /var/lib/mysql/mysql.sock: No such file or directory drwxrwxr-x 4 mysql mysql 4096 Oct 31 11:39 /var/lib/mysql Or maybe I'm trying to run mysql as the wrong user? [root@urquell2 ~]# cat /etc/my.cnf [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock # Default to using old password format for compatibility with mysql 3.x # clients (those using the mysqlclient10 compatibility package). old_passwords=1 [mysql.server] user=mysql basedir=/var/lib [mysqld_safe] err-log=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid ...so clearly mysql is trying to tell me something but can't use the right words to describe the problem. In the highly unlikely event that someone knows what mysql is trying to say, can they tell me how I might fix this problem? But more likely I would like to reinstall the RPMs since something is broke, right? Well that isn't so simple either. [root@urquell2 ~]# rpm -e mysql error: "mysql" specifies multiple packages [root@urquell2 ~]# rpm -qa | grep mysql-4 mysql-4.1.20-1.RHEL4.1 mysql-4.1.20-1.RHEL4.1 [root@urquell2 ~]# rpm -e mysql-4.1.20-1.RHEL4.1 error: "mysql-4.1.20-1.RHEL4.1" specifies multiple packages We are not even getting to the dependancy hell this will involve. So how do I fix this problem? I'd rather not pave the system and start from scratch, but honestly if I'd done that the moment that this problem manifested, I'd probably be up and running again by now. -- /\oo/\ / /()\ \ David Mackintosh | Public Key: dave(a)xdroop.com | http://www.xdroop.com/dave/gpg.html $ gpg --recv-keys --keyserver subkeys.pgp.net 4C032504 Mystery attachment? http://wiki.xdroop.com/space/GPG

I've built multi-terabyte systems around CentOS, and I'm in the process of writing up the "Poor Man's SAN" in my copious free time! ;) You don't mention what kind of RAID card you're using, but I stick with 3Ware. In a nutshell, all you need to do is a minimal install of CentOS from the first CD. Yum update everything. After this point, you can config Samba for your Windows clients, or NFS for other *nixes as needed. Could probably do AFS as well for Macs, but I haven't done that before. You'll have to wait until I get my howto done to configure hourly snapshots, etc.... HTH Mark

Microsoft Wireless Laser Mouse 6000 - WORKING
by Tom Lichti 31 Oct '06

31 Oct '06

I've found a few questions about trying to get this to work, I managed to do it, and thought I'd share: - get the evdev driver here: https://bugs.freedesktop.org/attachment.cgi?id=1745 - to install, run ./configure --prefix=/usr/X11R6, then make, make install. - edit your /etc/X11/xorg.conf like this: Section "InputDevice" Identifier "Mouse0" Driver "evdev" Option "Protocol" "evdev" Option "Dev Name" "Microsoft Microsoft Wireless Optical Mouse 1.00" Option "Dev Phys" "usb-*/input0" Option "Device" "/dev/input/event2" Option "Buttons" "9" Option "ZAxisMapping" "4 5" # wheel moves forward/back in the browser EndSection To figure out the "Dev Name", "Dev Phys" and "Device" settings cat /proc/bus/input/devices. I haven't gotten the tilt wheel to work yet, but everything else is good. You may want to swap buttons 2 and 3 as well using xmodmap. HTH Tom
