limits.conf
by Eugene Vilensky 29 Jul '09

29 Jul '09

Hello, I understand the function and reason of limits.conf, and I have some limited experience configuring values for (essentially single-user) Oracle systems. How do I understand correctly what my limits should be for multiuser system system, are there best practice guidance? Are there some typical settings this list has had experience with for multiuser environments? Appreciated, Eugene

postfix and mail origin checks
by Karanbir Singh 29 Jul '09

29 Jul '09

hi, Whats the 'robust' way to make sure email to a specific destination is only accepted if it came over the localhost:25 or /usr/sbin/sendmail route ? anything else should get a 5xx error. Emails to other destinations should remain unaffected. Using postfix/c4. Had a look around, and header_checks might be one way to go. -- Karanbir Singh : http://www.karan.org/ : 2522219@icq

Off-topic: strange problem with file size
by Marcelo M. Garcia 29 Jul '09

29 Jul '09

Hi I'm having a curious problem with some files. The account has 77GB of data[1], but there some files with more than 100GB[2], in fact, two of then have more than 200GB[3]. The OS is Opensuse 10.2 x86_64. Has anyone seem something like this? How can I inspect more closely what is going on? Thanks Marcelo [1] maryland:/maryland2 # du -sh alireza/ 77G alireza/ maryland:/maryland2 # [2] maryland:~ # find /maryland2/alireza/ -size +100G -print /maryland2/alireza/Restart/1to1-2/events-cfluid-rem-add-pasi/test.rsi /maryland2/alireza/Restart/1to1-2/lqfCyclic/Restart/a.rsi /maryland2/alireza/Restart/1to1-2/lqfCyclic/a.rsi maryland:~ # [3] maryland:~ # ls -lh /maryland2/alireza/Restart/1to1-2/lqfCyclic/Restart/a.rsi -rw-r--r-- 1 alireza cdrom 223G Jul 13 09:56 /maryland2/alireza/Restart/1to1-2/lqfCyclic/Restart/a.rsi maryland:~ # maryland:~ # maryland:~ # ls -lh /maryland2/alireza/Restart/1to1-2/lqfCyclic/a.rsi -rw-r--r-- 1 alireza cdrom 223G Jul 13 09:56 /maryland2/alireza/Restart/1to1-2/lqfCyclic/a.rsi maryland:~ #

DRBD on a xen host: crash on high I/O
by Andrea Dell'Amico 29 Jul '09

29 Jul '09

Hello, I have a couple of Dell 2950 III, both of them with CentOS 5.3, Xen, drbd 8.2 and cluster suite. Hardware: 32DB RAM, RAID 5 with 6 SAS disks (one hot spare) on a PERC/6 controller. I configured DRBD to use the main network interfaces (bnx2 driver), with bonding and crossover cables to have a direct link. The normal network traffic uses two different network cards. There are two DRBD resources for a total of a little less than 1TB. When the two hosts are in sync, if I activate more than a few (six or seven) xen guests, the master server crashes spectacularly and reboots. I've seen a kernel dump over the serial console, but the machine restarts immediately so I didn't write it down. Unfortunately I cannot experiment because I have production services on those machines (and they are working fine until I start drbd on the slave). drbd configuration is attached. Anybody has an idea of the problem? The crash is perfectly reproducible, and drbd seems to be the problem (maybe the Xen kernel helps?). Thanks in advance, Andrea -- Question: “Is there a God?” Answer: “No.” From the Official God FAQ, http://www.400monkeys.com/God/

I've tested the driver today (by connecting to the available access point) briefly and it didn't display any problems in functioning. Now, according to the news clipping from computerworld.com, by installing this, one would still use the proprietary Broadcom firmware, which, I suppose, comes along with the driver released by Broadcom at: http://www.broadcom.com/support/802.11/linux_sta.php Also, according to the Broadcom's README, all other "firmware kernel modules" have to be removed (or blacklisted) from kernel before installing this. I'm also willing of doing this, though, I am going to need some guidance in order for this not to take too long, since I've never done driver packaging before. A few questions for start: Ok, to build an rpm I need a spec file - this comes as a condition for packaging anything as RPM, right? Now, the only way to do everything else (i.e. blacklisting unwanted firmware files, importing kernel module, assigning modules to the devices ...) that I can think of, is via Bash script, or not?

Cleaning up some problems
by Sam Drinkard 28 Jul '09

28 Jul '09

Over the past year or so, I've collected several errors that some I have found the solution for, others, like the one below are quite befuddling. I get this one every week when /etc/cron.weekly runs. What the heck is the "S" or what it is looking for? Also, I've checked with cpan, and according to cpan, it says it doesn't know what NET::DNS is, yet if I do an i NET::DNS, it returns 150-some odd net::dns entries. I'm not totally familiar with cpan, and just started using it a short time ago. Still the man3/s is really screwey for some reason. There's not a package called "s" n the repositories is there? This is an x86_64 box updated as of yesterday after removing the httpd.1 stuff someone told me was the fix. Thanks again all.. Sam

28 Jul '09

I have CENTOS 5.2 on DELL server. I tried to install new HP3530fs MFP driver which I download from HP. It ask me install two dependency "cup-devel". while I try to install "cups-devel" from DVD and got error: # rpm -ivh cups-devel-1.3.7-8.el5.i386.rpm error: Failed dependencies: cups-libs = 1:1.3.7-8.el5 is needed by cups-devel-1.3.7-8.el5.i386 [root@MCG-ORA11 tmp]# rpm -qa|grep cups-lib cups-libs-1.3.7-8.el5_3.4 cups-libs-1.3.7-8.el5_3.4 the reason may come from "cups-libs" newer than "cups-devel". Anywhere I can download new version of "cups-devel"?
