Nagios 3 RPMs
Is anyone working on Nagios 3.x RPMs? If not, perhaps I'll whip some up and submit them to some appropriate repository. Geoff Galitz Blankenheim NRW, Deutschland http://www.galitz.org

centos IDM + sogo
Hello, We are testing the Centos LDAP Directory Server but are running into issues with applications (SOGo) authenticating against the LDAP system. The crux of my question is, can I just treat the Centos Directory Server as a generic OpenLDAP configuration on the client side? In more detail when I try to add account via ldapadd: -------------------------------- ldapadd -f sogo.ldif -x -W -D

Parallel/Shared/Distributed Filesystems
I'm looking at using GFS for parallel access to shared storage, most likely an iSCSI resource. It will most likely work just fine but I am curious if folks are using anything with fewer system requisites (e.g. installing and configuring the Cluster Suite). Specifically to our case, we have 50 nodes running in-house code (some in Java, some in C) which (among other things) receives JPGs,

device driver useage
Under Centos 5.X, how can I determine with 100% certainty what driver is associated with a given device other than referencing dmesg? For example, what tool can I use to tell for sure what driver is attached to my eth0 device? I have searched the web, but could not find anything that answered my question.

commercial support page
So we had that nice long thread about the commercial support page a week ago. There were a few recommendations on changes to the page. What next? It is not clear to me if any recommendations were accepted or are being debated internally or if this fizzled out somehow. Is there any process to this kind of thing other than a few developers agreeing it a good thing and then just doing it?

Cmake on Centos
Have folks been using Cmake on Centos5 without issues? I have installed an RPM for it, but I've been running into some apparent configuration issues. -geoff --------------------------------- Geoff Galitz Blankenheim NRW, Germany http://www.galitz.org/ http://german-way.com/blog/ -------------- next part -------------- An HTML attachment was scrubbed...

dm-multipath use
Are folks in the Centos community succesfully using device-mapper-multipath? I am looking to deploy it for error handling on our iSCSI setup but there seems to be little traffic about this package on the Centos forums, as far as I can tell, and there seems to be a number of small issues based on my reading the dm-multipath developer lists and related resources. -geoff Geoff Galitz Blankenheim

German Centos/Linux Group in Cologne/Bonn/Aachen
It seems there are a number of Centos users in the Cologne/Bonn/Aachen area of Germany. If there is not one already (and please let me know if there is!) I'd like to start a Linux User Group (including Centos) for this area. I'm way down in Blankenheim, though. Would someone like to volunteer a location? I envision alternating meetings between the three cities if possible... just

filesize limitation in CentOS or exim?
Hallo, today I had a surprising situation. Exim stopped. It's a German centos 5.3 64 Bit installation so the messages are partial in German. Then I tried a restart: [root at centos ~]# service exim restart exim beenden: [FEHLGESCHLAGEN] exim starten: /bin/bash: line 1: 6596 Die maximale Dateigr??e ist ?berschritten

Server packet loss and becomes unresponsive
? Does "ifconfig" or "dmesg" show any errors??? If the answer to those is no, I'd start running sar to see if there is abnormal behavior which could indicate a hardware problem.?? Of course, another possibility is a DDOS.? Do you have any kind security monitoring or protection in place? -geoff ----------------------------------------- Geoff Galitz Blankenheim,

mysql Workbench
Greetings, Is there a centos repo with mysql workbench anywhere. In the same vein, is there a publicly available build system for centos where people can submit the source tar.gz and get hotly baked rpm and the icing would be with some way to resolve dependencies?? It would be great to have one.. Regards and thanks, Rajagopal

IPSec VPN Setup?
Hello Everyone, I have been tasked at work with setting up a VPN connection from our server to a client's network. The only problem is that I have never done anything like this before, so I am not sure where to start. We are running CentOS 5.4 on our server. I do not yet know what the client is running for their VPN, the only thing I know of from the client, is we need to use IPSec for our

small window manager
What is an alternative X window manager, supported by CentOS, that has very small memory footprint? I want to avoid twm, because it defaults to interactive placement when not giving geometry options.

Slightly OT: check creation of a group
Hi, I'm currently writing an install script for an application, and my already limited Bash skills are a bit rusty. I want to check if a group exists, and if it doesn't, then create it. Only thing I found is: if [ grep medintux /etc/group ]; then continue else groupadd medintux fi Apparently I can't seem to "negate" the test, e. g. something like if !(grep medintux
