My server is based on UML. I am very happy with the service that is provided by UML. I concept of UML itself is very good. A small kernel module exists that allows UML.

I just love how I set my school machine up! With FC 6 as the host OS, and Windows XP as guest OS (naysayers, I use it only for Microsoft office.) for vmWare. Note: the best mode for my nVidia drivers was to enable best resolution my monitor could support. When entering full screen for Windows, I changed the options so that the guest OS screen resolution changes to the host OS. That works the best. As for the Windows XP installation, I had to speed it up by disabling certain options. Google “10 simple ways to speed up windows xp”.
I installed Sambha on the host OS and tunnelled it through a SSH connection through a third system. To use WinSCP, I need to use putty to create the tunnel. Finally, best of both worlds.

Additionally, I found a great program on sourceforge: DM2; http://dm2.sourceforge.net/. It had all that I needed and more. minimize to tray, multi-desktop support, floating icons etc.

use yumex to install kmod-nvidia drivers into the kernel. The drivers can be found in livina repository. One thing that it would not support is the ability to turn the monitor. My Dell monitor drivers supported turning the monitor.

I had a variety of times when I installed kernel using Linux. I absolutely adore Redhat. Long before Fedora Core did not come with support for Xen and for support for wireless systems, the procedure to install these things were to compile the kernel. I had compiled the kernel countless times on systems for supporting Coda File System.

For creating a faster kernel, modify the file to invoke gcc with compiler optimizations. It indeed produces a faster kernel which occupies lot of space.

Friends have asked me how to start and stop iptables. Following is the way to start and stop firewall on Linux:

$ /sbin/chkconfig iptables off
$ /sbin/service iptables stop

You can use webmin to setup IPTables.

A server I had been monitoring had multiple installations of apache web server. The system had about 10-15 httpd.conf files. I needed to figure out the httpd.conf that was configured to start website a. Below is a shell script that I wrote at the command promt:

for i in `locate httpd.conf`; do grep -l a.com $i;done
