Hello, I'm compiling a collection of stories from the systems administrator trenches. They can be short or long, funny or about a particularly challenging problem or period, or even something that appeared very technically challenging and ended up being something very simple. Stories which are more political would be ok so long as they do not have an agenda or can be interpreted as a

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

Hi all, I want to map an NFS share from a remote server to a local CentOS 5.4 server, but have a problem with portmap: root at mercury:[~]$ service portmap restart pmap_getmaps rpc problem: RPC: Unable to receive; errno = Connection reset by peer Stopping portmap: [FAILED] Starting portmap: [ OK ] root at

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

Hi, is there a way / software to find out which security patches my different CentOS systems are missing? Maybe with the according CESA announcement displayed? TIA, Frank.

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

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.

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

All, For a production environment, I'd like to setup CentOS XEN guests as lightweight as possible. I'd like the XEN guests to be able to send nightly email as all CentOS servers do, but there is no reason to run a mail server as the CentOS Dom0 already has an email server running that can act as an email smart host. The options that seem most appealing to me are either ssmtp or sendmail

Hey folks, I stumbled upon this while looking for something else http://www.linux.com/archive/feature/151340 And it is something I could actually really make use of. But right on that site they list 3 different ones, and so I'm wondering what all is out there and what I should use. Is there one that is part of the standard CentOS? thanks, -Alan -- ?Don't eat anything you've

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

Has anyone experience with WOL under Centos (5.3).? If so, how exactly do you put the machine to sleep, and how exactly do you wake it up remotely? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College Dublin

I have a CentOS 5.3 VM running under VMware on a WIndows XP laptop. Everything works fine when connected to the network. However, removed from the network, most everything in the CentOS VM takes minutes to complete. For instance, starting a new Terminal window takes over 3 minutes. I did an strace, and there are a couple of long waits when trying to open a socket

Hi all, There are rumours flying around about a supposed vulnerability in OpenSSH. Two details which I've seen mentioned many times are (a) that this exploit was used to break into a RedHat system running OpenSSH 4.3 plus backported security patches, and (b) that "recent" versions of OpenSSH are not affected; but it's not clear if there is any basis for these rumours. Given

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

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?

Hello all, I'm running a 64bit Centos5 setup and am trying to mount a gluster filesystem (which is exported out of the same box). glusterfs --debug --volfile=/root/gluster/webspace2.vol /home/webspace_glust/ Gives me: <snip> [2009-08-11 16:26:37] D [client-protocol.c:5963:init] glust1b_36: defaulting ping-timeout to 10 [2009-08-11 16:26:37] D [transport.c:141:transport_load]

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,

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.

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?
