I took over a custom firewall script from my older Suse machines to my Dom-Us and it works just fine. Doing the same for Dom-0 immediately killed all traffic for the VMs. As there was no need before I had been dropping everything on the FORWARD chain. After ACCEPTing all for FORWARD my VMs are happy again. What's best practice on Dom-0, what do you do? Can I restrict the forwarding, in

Just starting and playing around with Xen on Centos 5. I created a new VM (para-virtualized) with the Virtual Machine Manager, installed Centos 5 minimal on it, rebooted after successful installation. The VM console vanishes on shutdown and that's it. The VM id vanishes from the VM Manager and there's no way to get it back. It looks like the new VM doesn't exist. xm list shows only

All of a sudden yum hangs on a Centos 4.5 (updated to the latest patch before 4.6) when I try to use it. "clean metadata" didn't help. The output of -d5 shows it gets to the point of "Reading Local RPMDB" and then sits there. The process doesn't die, but doesn't seem to do anything from that point on. strace shows this: futex(0xb76dcae8, FUTEX_WAIT, 2, NULL I

I have a local mirror of CentOS5 base and updates. Now with 5 having become 5.1 and in case I just want to keep on updating (at the moment) is it enough that I update the mirror of updates or do I also need an update of the base repo?

Is there a program on CentOS which will sort my passwd/group etc. files by username or uid/gid? On Suse I can do this with a sysconfig switch and Suseconfig, is there something similar on RH-based systems?

The installed php on CentOS/RHEL is the CGI version. This means I should be able to get command line arguments with $GLOBALS[''argv''] or $_SERVER[''argv'']. That''s how the php documentation tells and how it works f.i. on Suse. However, on CentOS I get them only when I use the -n switch to php (no php.ini). The problem with -n is that php cannot find

We are serving the mp3s with .nsv endings since that is what the oddcast plugin seems to send by default when mp3 is

My update to 5.2 fails on one machine because of this error: Transaction Check Error: file /etc/init.d from install of chkconfig-1.3.30.1-2 conflicts with file from package AcronisAgentLinux-9.5.8076-1 file /etc/init.d from install of chkconfig-1.3.30.1-2 conflicts with file from package TrueImageAgent-9.5.8076-1 Obviously, both packages created (completely unnecessarily) the /etc/init.d

This is my first major version update after using a local repo. It seems that before I can "yum update" I have to fetch the complete new 5.2 base? Is this correct? When I run yum update it now fails with various strange dependency errors although all the updates are synced. When I change to using the original repo file it wants to download many many more and shows a lot of files that

Using CentOS 5.1 with Xen 3.2. I'm trying to install a fully virtualized system for the first time and doing this with an old Suse 9.0 (this probably would run paravirtualized, maybe it won't run, anyway, because of hardware problems). I start with virt-manager and after choosing "fully virtualized" it presents me two options for install media: iso image and CD-ROM or DVD,

I converted a physical maschine running CentOS 4.6 to a Xen VM on a CentOS 5 host. Almost everything was running when I decided to rsync /lib and /usr a while later in order to get updated files and get the one or two non-working programs to work. There are differences because of the xenU kernel I didn't think about. I forgot to exclude rpm database and /lib/modules. Because the synced

I found that lm_sensors got installed because of a dependency on my first Xen VM that I updated to 5.3. lm_sensors doesn't make sense in a VM. I thought, ok let's check after the update who wants it. However: rpm -q --whatrequires lm_sensors no package requires lm_sensors (same for --triggeredby with lm_sensors or the packages below) Trying to remove lm_sensors reveals these packages:

I usually don't setup any GUI on my Linux systems. Yesterday I installed with X and Gnome on a spare system for some testing and hit a problem. Right after login the system freezes. The system froze already earlier when I opted to test the sound card on the Welcome screen and when I login with the alternative login choice xterm and shut down it freezes when "saving mixer

I setup a kickstart file that contains only @core and several packages explicitely listed. postfix is listed, sendmail is not. And there's no package where I would think it needs cups. Nevertheless, after the install I now have postfix *and* sendmail on the machine and sendmail even being enabled. And cups is installed. How can I find out what forced them (and probably many other unwanted

I'm new to streaming or music hearing over the wire, I still prefer my old-fashioned stereo equipment :-) But a friend asked me to setup a shoutcast server for him, so I went out and installed it, played a bit with it and didn't like it. So I looked for an open source alternative and found Icecast. Installed fine, works fine. But there is one thing which puzzles me and I hope someone

Supposedly CentOS 5.1 should fix the problems with foreign keyboards, but I cannot see any change. The description in http://misterd77.blogspot.com/2007/11/xen-graphical-console-and-foreign.html does not work for me. Nothing changes. Has had anyone better luck? If so, how?
