Can anybody help me and explain to me how I can keep track of what the client is doing on same machine the client is running?

I can't figure it out...and I don't want to change everything everytime my system reboots just because I have an dynamic IP...

So please help me out! I already had problems how to put the user name in...it ended in having 3 entires in the stats now... Thor, Thor and da_zero....
