If you met this error when trying gii (yii framework), it’s probably the filters.
By Default, IP filters only allow 127.0.0.1. You need to add your IP address
'modules'=>array( 'gii'=>array( 'class'=>'system.gii.GiiModule', 'password'=>'password', 'ipFilters'=>array('127.0.0.1','::1'), ), ),
I found out a good tutorial here about installing Ubuntu Hardy 8.04 Server on Xen
Just follow the step-by-step and you are good to go !

If you are installing rjb on debian, you probably will need jni.h
sudo apt-get install sun-java5-source export JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun-xxxxxxxxxx sudo gem install rjb
$ gpg –keyserver wwwkeys.eu.pgp.net –recv-keys 4D270D06F42584E6
# You should see the following output while executing the above command.
gpg: Total number processed: 1
gpg: imported: 1
$ gpg –armor –export 4D270D06F42584E6 | apt-key add -
OK
$ apt-get update
[Note: Now update will work without the key error message]
