Intel 965 Chipset on 4.4 ?
by Redhat Admin 18 Dec '06

18 Dec '06

I have a nice new 965 chipset mobo with core 2 duo cpu. I was wondering if anyone has any experiences with this chipset and CPU with 4.4 ? Does the jmicron sata/pata interface work ? Are both cores recongnized with the right kernel ? Does EIST work ? Or should I wait for Centos 5 ? Cheers, Brian.

bring back sub shells
by Dustin Krysak 17 Dec '06

17 Dec '06

Good day, I have a centos 4.4 box (all yumed up). Now i have a program that has a sub shell - meaning something like the mysql command line, where once started it takes it's own commands, etc and keeps running until a "quit" command is issued. Now what I was wondering - is there a way to fork it to the background (something like # command & or ctrl -z) and have the subshell keep running? And also to be able to get back to the sub shell? For example, if i do run it with the & at the end it does what I want, yet obviously (to my knowledge) you can't get back to the subshell without killing it and restarting it. I have looked into the "screen" shell utility, which for the most part does what I needed, however after a few days the session had disappeared and I was not able to get back to it from another machine/ssh session. Are there any other options? Thanks! Dustin

Re: [CentOS] Help With Installation to USB Stick

Not a problem. If I need to add USB functionality into the kernel - the next question is what are the steps involved to do this? I was under the impression that running mkinitrd was all that needed to be done. Of course, I did run it and still got the same errors.

recompiling LVM or move to GFS for MySQL?
by Jed Reynolds 15 Dec '06

15 Dec '06

I'm planning some new mysql database servers and I've had problems with LVM in the past with snapshots. I've had advice from someone from MySQL AB to try out GFS because it's snapshotting is supposed not to be broken. Looking at some of the GFS documentation on Redhat.com makes it look like GFS might be or might not be a simple replacement if I'm just mounting it locally, but I've never tried it out. On the other hand, I've seen posts saying that if I do something like a rpm rebuild of LVM and udev and somesuch LVM snapshotting should work. I'd prefer to run a server configuration where I could do a scripted server build without having to install GCC and rebuild RPM packages when it came time to do a reinstall or create another replica server. Is LVM snapshotting going to busted forever, and should I go for GFS locally mounted? Jed

Re: [CentOS] Help With Installation to USB Stick

I went ahead and verified the labels on my partitions, and /dev/sda2 is labelled "/" and /dev/sda1 has a label of "/boot". Like I previously mentioned, I believe /boot is fine since grub loads - I am still at a loss as to why it can not see /. I installed the pendrive into my home PC running 4.4 and /dev/sda2 looks fine. I also ran fsck on it and it is clean. A while back, it was suggested that I run mkinitrd and include the USB drivers. I tried this, but it still wasn't recognized. If anyone can help me get pointed in the right direction, it will be greatly appreciated. Thanks!

Desktop link to URL with port number fails in CentOS 4.4
by Edward Diener 15 Dec '06

15 Dec '06

If I create a desktop item which is a link to a URL with a port number, opening the desktop item fails. I can create the desktop item by dragging and dropping the URL from my web browser, firefox. The desktop item, when I attempt to open it, brings up a message box with the title "Cancel Open?", a lightbulb icon, a message "Opening 'myURL:myPort'. You can stop this operation by clicking cancel.", and a single Cancel button. If I type directly into a terminal "firefox http://myURL:myPort/", firefox will correctly open that web page ( firefox is my preferred web browser ). So this is not a firefox problem but a Gnome desktop link problem evidently. Other URLs without a port number open correctly from a desktop link. Is there a way to fix this ? It probably has something to do with interpreting the URL as a Mime type for Gnome, but I do not know how I can correct the behavior so that URLs with port numbers are correctly passed to my preferred web browser, firefox.

15 Dec '06

Hi: I have a mirror of dag repository (http://apt.sw.be/redhat/el4/en/i386/dag/) in my intranet which is used by other servers to install/update rpms. I installed on every remote server the rpmforge rpm, edit the /etc/yum.repos.d/rpmforge.repo to fit with my intranet mirror, but when I run yum, I get this error: #yum -c rpmforge.repo search nagios Warning, could not load sqlite, falling back to pickle Repository rpmforge is listed more than once in the configuration Searching Packages: Setting up repositories //var/cache/yum/rpmforge/repomd.xml:1: parser error : Document is empty ^ //var/cache/yum/rpmforge/repomd.xml:1: parser error : Start tag expected, '<' not found ^ rpmforge 0 B 00:00 ftp://repository.cimex.com.cu/dag/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for rpmforge: Error: could not parse file //var/cache/yum/rpmforge/repomd.xml Trying other mirror.
