Apache Tomcat on my Linux server

I installed Apache Tomcat on my little Linux server (PIII-550Mz) since I'm going to test some java server application at home. I mainly based my installation on this howto with some little variation.
I first installed Java jdk 

 sudo apt-get install sun-java6-jdk

 Then I downloaded Apache Tomcat from my nearest mirror server

wget http://apache.fis.uniroma2.it/tomcat/tomcat-6/v6.0.18/bin/apache-tomcat-6.0.18.tar.gz

 Then I installed it

tar -xzvf apache-tomcat-6.0.18.tar.gz
sudo mv apache-tomcat-6.0.18 /opt/
sudo ln -s /opt/apache-tomcat-6.0.18/ /opt/tomcat

Installing TrueCrypt on EEEBuntu

Short after buying the EEEPC I also bought a 320 GB external USB hard disk to be used in support to EEEPC small internal drive. I decided (mainly because of my job) to secure, using cryptography, at least one disk partition. I'm not sure the cryptography settings I did choose would work against any professional hacker but they should be enough to stop  most 'curious' people who might, in any way, gain access to my disk . I decided to install TrueCrypt mainly because it's a multi-platform application so I could possibly prepare encrypted partitions to be used from both Linux and windows computers.
 Installation

I first downloaded  truecrypt-6.1a-ubuntu-x86.tar.gz  (the x86 32bit ubuntu compiled version) from its site downloads page. then I extracted and executed the installation program ...

 tar -xvf truecrypt-6.1a-ubuntu-x86.tar.gz
./truecrypt-6.1a-setup-ubuntu-x86 

The installation graphic user interface started and I simply had to click the 'Install TrueCrrypt' button and then agreed with the software license. Once installation was completed TrueCrypt icon was automatically placed in the 'other' folder.

Experimenting with Linux: MLDonkey

My little Linux server (PIII-550) works usually as Bittorrent download machine with Torrentflux running on the Apache server.  I desired to expand my little machine capabilities by installing some more download software. MLDonkey is a peer-to-peer client which let you download shared files in various network protocols.
 I did choose the easy way to install it using apt-get command:

sudo apt-get install mldonkey-server

 then I stopped the mldonkey server and edited the downloads.ini file in order to enable web acces from computers in my local network:

sudo /etc/init.d/mldonkey-server stop
cd /var/lib/mldonkey/
sudo vim downloads.ini

 I so edited the file adding my local network address range to allowed ips variable:

...
allowed_ips = [
  "127.0.0.1";
  "192.168.30.2/254";]
...
