I have a weird situation with a new installation of CentOS 5.4 x64, on a SuperMicro X7SBI server. The server has a SuperMicro X7SBi motherboard, board ATI ES1000 and Core2Quad Q9505 CPU. The kernel is When I login to the console, using a “17 CRT monitor (haven’t tested others), the screen is off-center to the [...]
Here’s a quick run-down on how to resize an existing LVM volume on Linux. I’m currently using LVM2. Let’s see what LVM volumes I have configured right now: [root@Rudi-PC ~]# lvscan ACTIVE ‘/dev/vg_rudipc/swap’ [5.80 GB] inherit ACTIVE ‘/dev/vg_rudipc/var’ [2.00 GB] inherit ACTIVE ‘/dev/vg_rudipc/home’ [20.00 GB] inherit ACTIVE ‘/dev/vg_rudipc/root’ [8.00 GB] inherit ACTIVE ‘/dev/vg_rudipc/data’ [10.00 GB] [...]
I often travel with work, and most of the times I carry a portable USB HDD (in my case I have a 100GB laptop SATAII HDD, in a Vantec E-SATA / USB enclosure), or a large USB Memory Stick. The USB HDD enclosure basically dock’s into a “docking station” in the PC, which then connects [...]

I found this cool game on clusters: http://www.rcac.purdue.edu/rackanode/ you basically need to build a cluster, and then process some data with it. You start off with some cash and need to choose your first server. Once the server is in place you’ll get some data to process and some more cash upon successful processing the [...]
So, I want to start looking into setting up a XEN cluster on Linux, which will provide high-uptime for Linux & Widows guest operating systems. This will be my first attempt to this, so I’m treading in deep waters, but it should be fun setting up. It’s rather late right now, so I’m not getting [...]
Often times it’s necessary to change the permissions on many files & folders recursively – i.e. change the permisssions on every file & folder. Todo so, login to your Server via SSH, and run the following commands as root. 1 2 3 find /home/username/public_html/ -type d -exec chmod 755 {} \; find /home/username/public_html/ -type [...]
I was looking for a way to properly monitor XEN VPS’s traffic, when I found this site: http://wikicompany.org/fs//system_management.html#traffic_accounting It has a long list Linux system management scripts Share and Enjoy:
For quite some time I’ve used BorgChat for Windows networks, and it works very well as a local chat client between users on the LAN, without having to use extra internet bandwidth. Recently, however, I wanted to join a Linux desktop to the Borgchat network, but since Borgchat doesn’t work on Linux, I need to [...]
I’ve run into quite a few odd issues with CentOS 5.1 x64 & the Xen kernel. One of them being the fact that it only sees about 480MB RAM, even though my server has 2GB RAM. So, searching the net, I came across this post: https://bugzilla.redhat.com/show_bug.cgi?id=250299 which states that grub-0.97-13 has a problem with mapping [...]
