==== UPS monitor ====

This is a small startup service which will send a shutdown signal to the server on power failure. I set it up with 60 sec pre-warning and 120 sec shutdown period.

  - tar -xvvf upsmon091_linux.tar
  - create script startUPSmon (#!/bin/bash, /etc/upsmon/upsmon /dev/ttyS0 60 120)
  - cp to /etc/init.d, chmod 755
  - update-rc.d startUPSmon multiuser
  - check the user right of /dev/ttyS0 to be root:dialout

==== phpmyadmin ====

Note that MySQL installs per default with user "root" without password. User root is not the system root, but rather a user with that name.

==== Java 6 ====

=== Installing the Java Runtime Environment ===

First you need to check multiverse repository enabled or not after that open a terminal window. Since you are going to be installing the JRE and the web browser plug-in, you’ll be using the following command from a terminal

  apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts

Once it downloads the packages and begins the installation, you’ll get a screen that contains the Sun Operating System Distributor License for Java and hit Enter to continue. You’ll see a dialog that asks you if you agree with the DLJ license terms. Select Yes, and hit Enter; the JRE will finish installing.

=== Testing Java Runtime Environment ===

You’ll want to confirm that your system is configured properly for Sun’s JRE. This is a two-step process.

First, check that the JRE is properly installed by running the following command from a terminal.

  java -version

open Firefox and type about:plugins in the address bar and check for the java plugin
