Symptom

You do not know your ip address

Cause

none

Solution

You can use the ifconfig command to get your ip address. When you run it as user, do not forget to give it the full path.

/sbin/ifconfig -> this will print a lot of information

To just get your ip address out of this bunch of information you can use the following line of code:

env LC_ALL=C /sbin/ifconfig eth0|sed -n '/addr:/s/ [^r]*..//gp'

Just try it, it works. (tested on debian)
