moving from live partitions to raid1 on an eserver
by David Milholen 13 Dec '09

13 Dec '09

I have a qtp (qmail toaster plus) machine on an ibm 326 eserver that has 2 sata 250GB drives. The problem I have is that when the Os was installed I thought I had hardware raid on but to my avail the Os assumed to drives an installed accordingly. Here is what df has for the partitions. # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdb1 240362656 17843040 210309816 8% / /dev/sda1 101086 11843 84024 13% /boot none 2047316 0 2047316 0% /dev/shm I need a raid in place on this machine. This is a live machine but I do have a lab machine to break. I really need to move this in a live fashion without losing the data of course I have complete backups to start a new if need be but it would be nice to be able to make the change and have raid1 in place to have a some better redundancy. I guess what I am asking what are the basic steps and what warnings to look for? Thanks --Dave

How do I link to custom libs without affecting system libs (LD_LIBRARY_PATH)
by Chris Morley 13 Dec '09

13 Dec '09

Hi, i am getting an issue with rtorrent that is related to my curl libaries. In summary it requires a later curl libary than CentOS 5.4 uses for its system files (CentOS uses curl libs version 7.15.5, rtorrent requires 7.19.2 or greater). To get around this I would like to download the latest curl version and compile and link to rtorrent without affecting system files. How can i statically link the latest Curl libs to my rtorrent build? I belive its to do with LD_LIBRARY_PATH but i am not sure howto proceed: wget http://curl.haxx.se/download/curl-7.19.7.tar.gz cd curl-7.19.7./configuremakemake install The above make install would overwrite or upgrade the existing curl, worried about breaking existing system! Many thanks in advance, Chris _________________________________________________________________ View your other email accounts from your Hotmail inbox.

ntop from rpmforge
by Ausmus, Matt 12 Dec '09

12 Dec '09

I don't know why I haven't signed up for this list before since we use CentOS all over the place. The list is very useful and it is good for me to participate and "give back" to the community. Anywho, I wanted to post this response to a thread that was created back in November 2008 about the ntop daemon failing to start. I'm currently setting up ntop as a NetFlow & SFlow collector and came across the issue. A quick refresher, the init script for ntop has an issue where it can't parse the ntop.conf file correctly if switches are entered before the "@/etc/ntop.conf". The suggested work around was to move the "-d -L" switches from in front of the "@/etc/ntop.conf" and put them behind it. This is definitely the fix. There is a caveat to that and I haven't found anyone that has mentioned it so I thought I would. According to the documentation, if you add the switches after the "@/etc/ntop.conf" those will override the configurations in the ntop.conf file. While this isn't an issue with the "-d" option, if you decide to use a custom syslog level and add it to the conf file, the "-L" switch after the conf file will override your custom log facility. In my init file I left the "-d" but removed the "-L" expecting me to put my own syslog entry in the conf file. ____________________________ Matt Ausmus Network Administrator Chapman University 635 West Palm Street Orange, CA 92868 (714)628-2738 mausmus(a)chapman.edu <mailto:mausmus@chapman.edu> "Man will occasionally stumble over the truth, but most of the time he will pick himself up and continue on." - Churchill's Commentary on Man

autofs and blank dvd
by m.roth＠5-cent.us 12 Dec '09

12 Dec '09

Well, I was about to burn a blank dvd. I put it in, and was setting it up in kb3... and my boss calls me, to tell me that my system's putting out error messages like crazy. I looked, and I assume it was autofs trying to mount the blank disk. How do I keep it from doing that in the future? mark

Thanks Steve for the heads up on the proper place to post this and that you've already submitted a fix. I just responded back to the list because this was the original posting place and wanted to make sure anyone else performing this fix until your patch goes through doesn't fall into the trap of putting the switches after the ntop.conf file. ____________________________ Matt Ausmus Network Administrator Chapman University 635 West Palm Street Orange, CA 92868 (714)628-2738 mausmus(a)chapman.edu "You can lead a horse to water, but if you can get him to float on his back, you've got something." -HARTLEY'S FIRST LAW -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of centos-request(a)centos.org Sent: Friday, December 11, 2009 9:00 AM To: centos(a)centos.org Subject: CentOS Digest, Vol 59, Issue 11 Message: 24 Date: Thu, 10 Dec 2009 15:00:54 -0500 From: Steve Huff <shuff(a)vecna.org> Subject: Re: [CentOS] ntop from rpmforge To: CentOS mailing list <centos(a)centos.org> Message-ID: <A0BA4C1D-A27C-475A-8489-54E009FABE44(a)vecna.org> Content-Type: text/plain; charset="windows-1252" On Dec 10, 2009, at 1:39 PM, Ausmus, Matt wrote: > Anywho, I wanted to post this response to a thread that was created > back in November 2008 about the ntop daemon failing to start.

Auditd fails to start : Connection refused
by Tom Laramee 11 Dec '09

11 Dec '09

Greetings: i have an x86_64 Centos5.3 box and i'm trying to run auditd. it fails on startup and this is the O/P at the end: config_manager init complete Error setting audit daemon pid (Connection refused) type=DAEMON_ABORT msg=audit(1260554376.697:5674): auditd error halt, auid=4294967295 pid=32702 res=failed Unable to set audit pid, exiting The audit daemon is exiting. Error setting audit daemon pid (Connection refused) the only thing i've learned from asking google is that it's a potential problem with the interaction between selinux & auditd, but i haven't found a solution. two questions: 1. anyone know what the problem is? (that or my next step in diagnosing it) 2. if i can't solve it, is there an alternative method for adding watchpoints to directories such that i can be notified of WRITE events for files in that directory (and preferably for all of it's subdirectories)? My kernel version is 2.6.18 (full info below). The audit version is audit.x86_64 0:1.7.13-2.el5 thanks --tom Name : kernel Arch : x86_64 Version : 2.6.18 Release : 164.6.1.el5 Size : 18 M Repo : updates Summary : The Linux kernel (the core of the Linux operating system) URL : http://www.kernel.org/

poweredge 1950 hangs at starting udev
by Ryan Pugatch 11 Dec '09

11 Dec '09

Hi all, I have a PowerEdge 1950 that was acting weird. Network connectivity was only performing at a quarter of what was expected (if that). Even if I scp'd something to localhost it would perform poorly. Rather than fight with it, I just decided to reload it. It was running 5.3, and it is now running 5.4. However, when I go to boot it gets stuck at starting udev. If I let it sit long enough it will then give me errors with something along the lines of: Dazed and confused, but trying to continue Uhhuh. NMI received for unknown reason 00 Do you have a strange power saving mode enabled? Wondering if anyone has an idea.. Thanks, Ryan
