Apache Config
by Joseph L. Casale 18 Jan '09

18 Jan '09

I am trying to setup moinmoin and my apache virtual host config looks like this: <VirtualHost *:80> ServerName www.example.net DocumentRoot /<path to doc root> AddHandler cgi-script .cgi Alias /moin_static181/ /usr/local/share/moin/htdocs ScriptAlias / /<path to doc root>/cgi-bin/moin.cgi </VirtualHost> But this breaks every link in moinmoin unless there is something in Alias like: Alias /foo /<path to doc root>/cgi-bin/moin.cgi which then leaves http://www.example.net/ as 404 sicne there is no default doc in the root? How can I avoid this so the wiki is available at the root? Thanks! jlc

Hi all, I have a new motherboard I am trying to install centos 5.2 x86_64 on. it has the mcp78b chipset. seems like the SATA disk is not detected. tells me no install media found. I tried the install line with "pci=nomsi" that did not help. I tried changing the SATA in the bios to AHCI and that did not help. Any thoughts on something to try? Jerry

vixie-cron package from RHEL 5 FasTrack?
by Alfred von Campe 16 Jan '09

16 Jan '09

What is the best way to get the RPM described in the following URL installed on CentOS 5.2: http://rhn.redhat.com/errata/RHBA-2008-0586.html I have users who can't run cron jobs because their home directories are NFS mounted, and I believe installing this RPM would fix the problem. I remember reading that the CentOS developers are working on supporting the RHEL FasTrack mechanism, but other than that I am not very familiar with the purpose and workings of FasTrack. For instance, will RHEL 5 Update 3 (and therefore CentOS 5.3) include this fix? Why wouldn't this RPM make it into the current update stream since it was released 6 months ago? Alfred

postfix relay and mail host for HPC cluster
by Tony Schreiner 16 Jan '09

16 Jan '09

I've so far been unable to make the following work: I have a small cluster with a master node ( called bayes.bc.edu on the public network, and called master.cl.bc.edu on the internal 10.0.0.0 network). and a number of nodes which are purely on the private network. I want the master to receive mail and deliver locally (or use .forward and alias rules) to messages sent from the nodes to user@master, and I want it to relay non-local addresses to my campus relay host which is another machine. The relay part works ok, all mail addressed in a form that my campus relay host recognizes gets delivered. The problem is that mail to user(a)master.cl.bc.edu (the internal name) gets relayed to the campus relay which does not know about the host name master.cl.bc.edu because that is defined on a private DNS server for the cluster, and the campus relay rejects the message. How can I get my cluster master to not relay messages addressed to @master.cl.bc.edu? The queueing/resource manager (torque/pbs) wants to send automatic status messages to user(a)master.cl.bc.edu and that cannot easily be changed. Mail MTA is postfix for both master and nodes Some postfix settings on the master. myhostname = bayes.bc.edu mydomain = bc.edu myorigin = bayes.bc.edu inet_interfaces = master, localhost mynetworks = 10.0.0.0/24, 127.0.0.0/8 relayhost = mail.bc.edu and some settings on the nodes mydomain = cl.bc.edu myorigin = bayes.bc.edu inet_interfaces = localhost relayhost = [master.cl.bc.edu] Thanks for any help, Tony Schreiner

Squirrel 1.4.8-8.el3.centos.1
by Henk van Lingen 16 Jan '09

16 Jan '09

Hi, Last tuesday I upgraded squirrelmail on two centos-3 mailservers. squirrelmail-1.4.8-8.el3.centos.1, 2.4.21-58.ELsmp, CentOS release 3.9, httpd 2.0.46 Since then I have some users who have problems with their sessions. They are logout out every now and them, and some sent mails have another user address in the From header. It looks like squirrel is mixing up sessions? Those users have used fresh browser sesions. Anyone else seeing this? regards, -- Henk van Lingen, Systems Administrator & DBA (o- -+ Dept. of Computer Science, Utrecht University. /\ | phone: +31-30-2534107 v_/_ http://henk.vanlingen.net/ http://www.tuxtown.net/netiquette/

3Ware 9650SE tuning advice
by Ray Van Dolson 16 Jan '09

16 Jan '09

Hello fellow sysadmins! I've assembled a whitebox system with a SuperMicro motherboard, case, 8GB of memory and a single quad core Xeon processor. I have two 9650SE-8LPML cards (8 ports each) in each server with 12 1TB SATA drives total. Three drives per "lane" on each card. CentOS 5.2 x86_64. I'm looking for advice on tuning this thing for performance. Especially for the role of performing as either an NFS datastore for VMware or an iSCSI one. I set up two volumes (one for each card); one RAID6 and one RAID5. I used the default 64K block size and am trying various filesystems in tandem with it. I stumbled across the following recommendations on 3Ware's site: echo "64" > /sys/block/sda/queue/max_sectors_kb blockdev --setra 16384 /dev/sda echo "512" > /sys/block/sda/queue/nr_requests But am wondering if there are other things I should be looking at, including changing the IO scheduler. Any particular options I should use with filesystem creation to match up with my RAID block size? I also noted that there is a newer 3Ware driver (2.26.08.004) available than the one that comes stock with CentOS 5.2 (2.26.02.008). Not sure if I can expect performance improvement by "upgrading", and I imagine I'd have to mess with my initrd file in any case or boot with a driver disk option and blacklist the built-in driver... Thanks for any feedback! Ray
