3ware performance in CentOS
by Florin Andrei 30 Jun '08

30 Jun '08

Have a look at these pages: http://www.bofh-hunter.com/2008/06/13/3ware-performance-in-centos/ https://bugzilla.redhat.com/show_bug.cgi?id=444759 I'm comparing the default 5.1 64bit kernel with the patched one posted in the bug report (kernel-2.6.18-53.1.21.el5.bz321111.x86_64) and I don't quite see any significant difference in write performance for this command: dd if=/dev/zero of=/logs/test bs=100M count=1000 (100GB of data, written in 100MB blocks) It's a Supermicro server, the motherboard is (according to the stuff painted on the mobo itself) Super X7DBI+, Intel Xeon L5420 with 8 cores total, 3ware 9650SE using the driver from the manufacturer's site. I tested 2 disks in a mirror RAID volume. Results: kernel time speed ====== ==== ===== patched 75min 23M/s original 51min 34M/s patched 48min 36M/s original 61min 28M/s -- Florin Andrei http://florin.myip.org/

What are these TCP errors telling me?
by Sam Drinkard 30 Jun '08

30 Jun '08

Lately, the error messages below have been showing up in the log for the past 3 days. Is something broken, or someone trying to break in or what? I'm completely clueless about this. If you could, since I'm receiving the list in digest form, cc a copy directly to me? Many thanks...

system-auth.rpmnew
by Kai Schaetzl 30 Jun '08

30 Jun '08

The upgrade to 5.2 creates /etc/pam.d/system-auth.rpmnew. I see that /etc/pam.d/system-auth actually is a symlink to system-auth-ac. Is it recommended to replace that symlink with the rpmnew file?

xorg and backlight
by Andrej Moravcik 29 Jun '08

29 Jun '08

Hi all, I have found one problem after upgrading to CentOS 5.2 x86 on my HP Compaq nx7010 laptop. When I close and open lid, backlight is not turned on again. I can see my desktop, but the only thing I can do is press CTRL+ALT+BACKSPACE to restart X11. Then the backlight is restored. xorg.conf is generic, created by installation process. I use ATI proprietary driver 8.28.08 (the last which support Mobility Radeon 9200). I would appreciate any hint or help.

spam filtering with centos 5.2
by John R Pierce 29 Jun '08

29 Jun '08

In the past I've used a combination of spamhaus combined RBL's and Spamassassin with Mailscanner as my spam recipe, but this stopped working very well for me well over a year ago. As many of the users of the couple small/personal mail servers I run are NOT technical people, and use POP to read their mail, 'training' spamassassin is difficult at best. Once upon a time, using the Rules Du Jour scripts from the SARES project worked pretty well, but that has been shut down, and really hasn't been functional in over a year. I've just rebuilt a friends mail server with centos 5.2 (it was running FC3 or something before) and would like to setup them up with a decent anti-spam recipe that doesn't require extensive tinkering or training. does anyone have a good recipe for this? Ideally I'd like something purely RPM based that doesn't require extensive configuration and tuning. I've never setup razor before, how well does that work if the mail users aren't in a position to feed it training data?
