Do you need to roll your own PHP build to support MySQL now? I don't see support built into the included libphp module.. Thx, CC

DBD::SQLite no longer works under mod_perl2, generating an error which is "not an error" upon any attempt to select something. (The same selects all work in a command-line script.) (https://rt.cpan.org/Ticket/Display.html?id=47983) I tried to sign up for a centos bug report username, but the signup form is buggy, the captcha never works.... Any chance someone can try to fix this? Mark

etc passwd and groups file
by Carlos Santana 29 Jul '09

29 Jul '09

Hi, I need to maintain a same user/group list on multiples systems. Can we just copy the same passwd and groups file on all machines? If we create a new user on one system then I will need to copy this to all other systems. This is quite cumbersome. Any suggestions? - CS.

Software RAID-1 partition constantly syncing
by Jeff Gregor 29 Jul '09

29 Jul '09

I have a partition set up as software RAID-1 on a CentOS 5.3 machine. Today, the system was rebooted, when it came back up I noticed that it had started to resync. It completes the sync, then immediately starts again. From the log: Jul 29 09:46:02 cbserver kernel: md: syncing RAID array md2 Jul 29 09:46:02 cbserver kernel: md: minimum _guaranteed_ reconstruction speed: 5000 KB/sec/disc.

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

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?

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?
