BIND9 - automatic zone definition replication to slave
by Martin Šťastný 01 Jun '11

01 Jun '11

Hello, I have simple question - is there a way to automatically replicate zone definition (not zone itself - this is easy) to slave server using BIND9? Is it BIND built-in or are there prebuilt scripts? Or I have to write that script on my own (started by Cron, transfer file with zone names, create conf file and finallly restart BIND?)? Thank you in advance

the tag Obsoletes: in spec files
by Philippe Naudin 01 Jun '11

01 Jun '11

How exactly to use the tag "Obsoletes:" in a spec file ? I need to offer texlive to users on Centos-5.6, so I packaged it (based on a Mandriva src.rpm), and that works. But I want rpm to *replace* tetex by texlive, instead of just adding texlive, when users do a : $ yum install texlive (we have a local repo here). So I added this line in texlive.spec : Obsoletes: tetex and of course I rebuilt the package, and (of course) that just don't work, despite tetex is listed among the Obsoleted packages : $ rpm -qp --obsoletes texlive-20110312-0phn.x86_64.rpm dvi2tty <= 5.3.1 jadetex kpathsea <= 20100722 kpathsea-devel <= 20100722 kpathsea-static-devel <= 20100722 pdfjam <= 1.21 ps2eps <= 1.64 tetex tetex-context tetex-devel tetex-dvipdfm tetex-dvips tetex-dvilj tetex-latex tetex-mfwin tetex-texi2html tetex-usrlocal tetex-xdvi etc... (tetex is the CentOS one : tetex-3.0-33.8.el5_5.6) Can someone explain me why this fails, and eventually an other way to solve this problem ? Thanks, -- Philippe

[CentOS 5.5] Program/method to test integrity of the system/packages
by giggzounet 31 May '11

31 May '11

Hi, we have a cluster. The master has CentOS 5.5 on it. At the moment it crashes randomly...perhaps a hardware problem...no idea. But to eliminate a software problem I would like to test the integrity of the system or of the installed package. Is it a way to check if the binary installed by binary.rpm is the good one ? with md5sum or something else ? Thx a lot, Guillaume

Getting the return value of the last command run
by Dotan Cohen 31 May '11

31 May '11

All commands return a value, usually 0 if run properly. For instance, try: $ ls && echo "done" $ lsd && echo "done" The echo command is only executed if the ls command exited successfully. If one did not add the echo command with the && after a command, how can he determine if the command exited successfully? I have a particularly troubling script that gives does not mention if it exits successfully or not. I could modify it (and probably will some day) but in general I'd like to know the answer to this question as a learning experience. Thanks. -- Dotan Cohen http://gibberish.co.il http://what-is-what.com

scheduling differences between CentOS 4 and CentOS 5?
by Matt Garman 30 May '11

30 May '11

We have several latency-sensitive "pipeline"-style programs that have a measurable performance degredation when run on CentOS 5.x versus CentOS 4.x. By "pipeline" program, I mean one that has multiple threads. The mutiple threads work on shared data. Between each thread, there is a queue. So thread A gets data, pushes into Qab, thread B pulls from Qab, does some processing, then pushes into Qbc, thread C pulls from Qbc, etc. The initial data is from the network (generated by a 3rd party). We basically measure the time from when the data is received to when the last thread performs its task. In our application, we see an increase of anywhere from 20 to 50 microseconds when moving from CentOS 4 to CentOS 5. I have used a few methods of profiling our application, and determined that the added latency on CentOS 5 comes from queue operations (in particular, popping). However, I can improve performance on CentOS 5 (to be the same as CentOS 4) by using taskset to bind the program to a subset of the available cores. So it appers to me, between CentOS 4 and 5, there was some change (presumably to the kernel) that caused threads to be scheduled differently (and this difference is suboptimal for our application). While I can "solve" this problem with taskset, my preference is to not have to do this. I'm hoping there's some kind of kernel tunable (or maybe collection of tunables) whose default was changed between versions. Anyone have any experience with this? Perhaps some more areas to investigate? Thanks, Matt

Re: [CentOS] Where is the Centos Linux 5.5 kernel syscall handler for mmap?

Hi. Sorry for the late reply, but I did not get the message that was archived. I stumbled upon it here: http://osdir.com/ml/centos/2011-05/msg01193.html All I got was this message: I am out of the office until 06/11/2011. I will be out of the office starting 5/27/2011 and will not return until 6/12/2011. I will respond to your message when I return. Note: This is an automated response to your message "CentOS Digest, Vol 76, Issue 28" sent on 5/28/2011 9:00:02 AM. This is the only notification you will receive while this person is away. In response to your question: "Thank you for your suggestion about doing a grep of the source code. We found mmap.S in ../sysdeps/unix/sysv/linux/i386. We looked in mmap.S and found a lot of assembly code. Could you please tell us if any of the assembly code call the kernel syscall handler for mmap.s? Also, we ran make for the kernel Makefile and we obtained the following result shown below. Could you please suggest us how to fix the kernel Makeconfig so that it skips over libc_pic.os? Thank you for your help." May I suggest you join the LKML? http://www.kernel.org/pub/linux/docs/lkml/ I'm sure they are alot more knowledgeable concerning things like tweaking the internals of the Linux kernel.

I have difficulty with this statement on so many levels that it is hard to know where to begin. Perhaps the most egregious is the mindless equating of server with host. What measurable benefits accrue to a firm from 'breaking the legacy', whatever that means. > 2.

Personally, my experience is that, if anything, running multiple systems on a vm host measurably increases the administrative burden per host. For one thing, you now have multiple instances to update and to keep secure whereas before you had one OS to worry about. If we had tens or hundreds or thousands of servers then yes, I can see the benefits. We, however, do not deal with equipment on that scale. > 3.

I suppose that moving VM instances as file systems provides a real value by eliminating the setup and configuration required to get bare metal to flash up in a usable fashion. This is in fact the only area that I see a real advantage to VM over bare metal installs. > 4.

Again, how is this accomplished and what are the advantages over a single OS install? None of the above claims have anything to do with VM per se as far as I can see. -- *** E-Mail is NOT a SECURE channel *** James B.

PHP Source
by Ron Young 30 May '11

I have a pressing need to compile a utility called odbtp into php on my new 64 bit machine with an AMD chip that is currently running CentOS 5.6. Where can I find the source files for the CentOS recommended versions of php. I have searched the CentOS and related repository sites and can find php in several places but not the source files. Thanks in advance. Regards, Ron Young 919-621-9015 http://www.linkedin.com/in/ronhyoung +++++++++++++++++++ Little tiny dreams require little tiny thoughts and little tiny steps.
