No, it won't. OffTopic in a kannel list, but have you configured you Suse to run portsentry or any other portscaner daemon ? I remember that portsentry opens some honeypot ports and when anyone else connects to those ports, portsentry will could reply back, probably with its own portscan. > > > Thank you very much, > Andy > > > -- <BR/>
