What is needed to run a X Server on Debian Linux

Today I installed a Debian (etch) system from scratch and wanted to start a X server... hm ... no X server on a fresh installation. So what packages do I have to install to get a X server running on my system?

apt-get install x11-common xserver-xorg-core xserver-xorg xfonts-base xterm

If you prefer a small and fast window manager and no desktop like KDE or Gnome try out enlightenment.

apt-get install enlightenment

Running Confluence behind Apache2

I decided to run my personal Confluence installation behind the Apache2 server running on my Debian Linux box using the mod_proxy configuration. I followed the instructions on Atlassians documentation pages (When using Debian it is described in the Jira docs) but ran into a problem afterwards.
Confluence was not accessible and I received a "Permission Denied" error when accessing confluence over HTTP (
The solution was to enable the Apache module proxy_http:
a2enmod proxy_http
After a Apache restart everything worked as expected!

Open Source Monitoring Software

Ever heard of Hyperic ( Well, I would not be surprised if you haven't. I stumbled across this free and easy to use software a few days ago when I was searching a for a monitoring software to monitor my JBoss and Tomcat servers.
This software is able to monitor nearly everything (Application Servers, Databases, Servers, Networks, etc.) and comes free of charge. It's well designed using a JBoss Application server and written entirely in Java.
All you have to do is to install the small agent on the machine you want to monitor and install the server software to gather all informations. The GUI is completely available as a web frontend so every administrator in your company's internet can monitor the servers without installing additional software on their clients.

Linux IMAP Server using Postfix and Procmail

I switched from POP3 to IMAP on my Debian Linux box and had some problems setting up my local delivery transport using Postfix and Procmail. I use Dovecot as my IMAP server and I decided to move from mbox format to Maildir.
To make this happen I had to tell Postfix that I now use Maildir instead of mbox. Just add the following line in /etc/postfix/
home_mailbox = Maildir/
Now you have to tell Procmail to use Maildir instead of mbox. To do this, create a file called .procmailrc in your users home directory and add the following line:
Now all my problems are gone and I have a working IMAP system using:
  • Dovecot (IMAP Server)
  • Postfix (MTA)
  • Procmail (LDA)
