So I Won't Have To Remember

Debian stopped including mkisofs in sid. Instead they have a program called xorrisofs. Here is how to use it to create iso images from a directory.

iptables can block Internet access to application running as a specific group or user. So to enable application specific Internet blocks can be achieved this way:

Add a group which we can then add to the blocked list. I am adding here a group named 'nosoupforyou'

Set a password for this group

Add iptables rule to enable blocking. This will drop all packets created by nosoupforyou


finally run a program as this new group

You will notice that if you start firefox this way, you can not access any sites at all. You can just start any other programs you would like to block from accessing Internet.
