Minimal server install and a few other questions.....
by Bards1888 27 Oct '05

27 Oct '05

Hello, I was wondering what is the smallest install that anyone has managed with 4 (4.2 to be precise) ? I'm looking at a machine running as a VPN in a DMZ, so I'm going to remove/NOT INSTALL things like gcc, X, etc. I'm planning on putting this on a 1gb USB stick and booting from it. That reminds me, was there going to be a 1 CD server install image ? The other thing I noticed is that if I install on x86_64 I get around 400mb in /usr/lib *and* /usr/lib64, is this entirely necessary ? Especially if I dont want the 32bit stuff ? How can one tell which packages are responsible for the libs in /usr/lib/ ? I tried a random filem from that directory; [root@services lib]# rpm -q --whatprovides libOggFLAC.so.1 flac-1.1.0-7 [root@services lib]# rpm -qa | grep -i flac flac-1.1.0-7 [root@services lib]# rpm -qi flac-1.1.0-7 Name : flac Relocations: (not relocatable) Version : 1.1.0 Vendor: CentOS Release : 7 Build Date: Tue 22 Feb 2005 10:56:45 EST Install Date: Wed 13 Apr 2005 11:50:50 EST Build Host: guru.build.karan.org Group : Applications/Multimedia Source RPM: flac-1.1.0-7.src.rpm Size : 707386 License: LGPL/GPL Signature : DSA/SHA1, Sun 27 Feb 2005 06:37:33 EST, Key ID a53d0bab443e1821 Packager : Karanbir Singh <kbsingh(a)centos.org> URL : http://flac.sourceforge.net/ Summary : An encoder/decoder for the Free Lossless Audio Codec. Description : FLAC stands for Free Lossless Audio Codec. Grossly oversimplified, FLAC is similar to Ogg Vorbis, but lossless. The FLAC project consists of the stream format, reference encoders and decoders in library form, flac, a command-line program to encode and decode FLAC files, metaflac, a command-line metadata editor for FLAC files and input plugins for various music players (the xmms plugin is in a sub-package). I cant see an 'arch' in there anywhere, however on the Centos DVD I found flac for both i386 and x86_64. So why are there rpms for both archs with the x86_64 build ? Thanks in advance.

cache memory not being used
by Dave 27 Oct '05

27 Oct '05

Since I upgraded to 4.2 it looks like the cache memory doesn't go over about 70K or so. I have over 700K free and it started using swap, which doesn't normally happen for a few days or so. Any hints on what might be up? This is just after a compile and the cached is only 75k total used free shared buffers cached Mem: 1032848 263992 768856 0 4612 75628 -/+ buffers/cache: 183752 849096 Swap: 1052248 18260 1033988 On a side note, anyone able to have Xorg running for more then 14 days? It consumes about 750megs after 14 days or so.

Opteron + Nvidia + Centos 4.2 i386 = Thud
by Jake Grimmett 27 Oct '05

27 Oct '05

Dear All, Just returned from vacation and was delighted to see that Centos 4.2 is now on the mirrors. Unfortunately the new i386 version is giving us problems on our dual Opteron workstations with Nvidia graphics cards... Basically, nine times out of ten, the boxes will hang when they try to re-load X... and just sit there with the keyboards Caps and Scroll lock LED's flashing. The only way out is the reset button. The working fixes I have so far found are to either use a non-smp kernel (2.6.9-22.EL) or to use the VESA X driver. Neither is a proper solution as the machines are used for 3D modeling. Non working fix attempts have included: passing acpi=off to the kernel trying Nvidia driver versions x86-1.0-7676, x86-1.0-7667 and x86-1.0-6629 Installing Centos from scratch as well as upgrading Centos 4.1 to 4.2 (via up2date) Trying three different Nvidia cards (Geforce 6800U, 5900 and a MX200) Trying two different motherboards (Tyan thunder K8W and Tiger K8W - both are AMD 8000 chipset based) Trying two different pairs of Opteron 240's and Opteron 246's. As things used to work more or less perfectly with i386 Centos 4.1 (2.6.9-11.ELsmp and the Nvidia 7667 driver) I'm starting to feel a little stupid - any chance that someone could put me out of my misery and suggest some solutions?

RE: [CentOS] apache 403 forbidden problem.
by Colht, Charles 27 Oct '05

In CentOS 3, look for mrtg.conf in /etc/httpd/conf.d. This file configures /mrtg for localhost access only. Change the 'Allow from' line to something sensible and it should work. That drove me nuts for a while until I found it.

I did read that before, but overlooked it. If using CentOS-3.x and httpd from there then selinux is not available. If on CentOS-4.x then selinux might be an issue. *********************************************************************************** This transmittal may contain confidential information intended solely for the addressee.

Re: [CentOS] starting a java application as a service
by Brian T. Brunner 27 Oct '05

27 Oct '05

I don't recall seeing a response to this request, and I'm nothing of an expert in Java, so here's a some-what educated guess: Where you invoke "/usr/bin/java -cp /usr/local/lib/java/jes.jar Jes $JESARGS" put "daemon " in front of that line. daemon /usr/bin/java -cp /usr/local/lib/java/jes.jar Jes $JESARGS and give that a whirl. (daemon is the function brought in by the script processor for startup services that backgrounds/detaches the call to the service itself Brian Brunner brian.t.brunner(a)gai-tronics.com (610)796-5838 >>> ByrneJB(a)Harte-Lyne.ca 10/24/05 05:19PM >>> I have a single requirement to launch a java application on startup as a service. The application is shipped in a file called jes.jar. It requires three arguments: a dotted quad IP address, an initial service port, and a translated service port. I can get the application running as a console command. Can someone point me to a site that documents how to script a sys V init.d style script so that I can run this as a daemon process? I tried copying a script in the age old fashion but I seem to be missing something(s). Lastly, I vaguely recall that there is a way to capture the pid of a program started in the shell but I cannot find any reference to it.

I will also running EDA tools like PriteTime, and Magma on this server. Does CentOS has any issues with these tools? your help on this question is appreciated. Thanks Siva.

Two small issues after upgrade to 4.2
by Kai Schaetzl 27 Oct '05

27 Oct '05

I made a yum update to 4.2 yesterday. The first "major" update I did on CentOS, I'm only using it for a few weeks now, starting with 4.1. Mainly for evaluation for a prospected migration from Suse to CentOS. Basically the update went very well, fast (only 180 MB needed to be installed) and smooth. But there were two small issues where I don't know why they happened: 1. There was a (actually two) spamassassin.rpm of SA 3.1.0 installed, the rpm was built from the tar.gz sources for SA with the specs file provided with it. It produces two files for installation: perl-Mail-SpamAssassin and spamassassin. The update wiped them and installed SA 3.0.4 with this message: Obsoleting: perl-Mail-SpamAssassin.i386 0:3.1.0-1 with spamassassin.i386 0:3.0.4-1.el4 Shouldn't this update get skipped because the version information is higher than the CentOS package? I found several mentions that I can exclude packages from yum updating. How can I do this? I don't want to update only specific packages, I only want to exclude a very few packages. 2. sshd seems to start twice or so since that update. No problems with ssh, though. from boot.log: Oct 24 14:00:16 nx05 sshd: succeeded from warn log: Oct 24 14:00:16 nx05 sshd[1737]: error: Bind to port 22 on 0.0.0.0 failed: Address already in use. Same thing happens when I restart sshd and even when I reload it. There was a new sshd_config installed, I think I read something about removing ssh 1 protocol from it. This can't be the cause. There's only one instance of sshd running apart from the children for actual logins. Why is this happening, how to fix it? There is another question that arises in this context: will a yum update always overwrite with new configuration files, if that file got changed from the originally installed one? I'm used from Suse that new configuration files get saved with another extension if the original file got changed or in some cases it overwrites the file but copies the old file to a backup. I can also expressly exclude some config files from overwriting via sysconfig (if I remember correctly), can I do similar with CentOS?
