Maybe I'm paranoid and if you look into my XP system you will think so - why? Because of the amount of steps I've taken to secure my system.
I have a hardware firewall (router - stealth on all ports) so the suggestion from scorp123 is not what I was looking for - but thanks a lot anyway. Besides isn't IPtables set to have all ports closed on the outside?
I was thinking more like if something followed Firefox or another program in and then tried to log in. I'm not sure if such attempts ends up inside or outside the account for all times.
When I wrote this post I suddenly realised that I was about to miss an appointment so I logged out without reading it and hurried away. Thus the preceding sentence is not the most brilliant I've written
Even without a running server I've seen a few failed log in attempts in the logs in XP - when you are already logged in you are not logged out only the "log in person" is denied entry. (correct me if I'm wrong)
It is perhaps really not necessary if you are not running a server of some kind.
