Connection out from unknown process

[BubikolRamios]

If I look at firestarter actve connections I see that there are several connections from me to some dynamic ip, on various ports. I have no idea what that is.

1. How to find which process is doing this connection ?
2. This is sure nothing good, how to kill /block connection ?

Thanks.

Take a look at the man pages for netstat and lsof.

2. This is sure nothing good, how to kill /block connection ?

iptables
