Dear Jürgen Eder, concerning your mail sent on Mon, 29 Nov 1999 let me reply the following:

Big deal, you speak of port scans like they are something illegal! There is nothing illegal about port scanning.

Right. But, as as my log-files show, in many cases an attack follows the port scan. I _always_ contact the gateway admin if I find a port scan, and, in some cases, they find out that somebody intruded in their systems. So I think it is helpful to inform admins about port scans that come from their systems. It's one way to avoid attacks followed by port scans.
