[Mono-list] Portscanner School Project...Probably using System.Net class
Sat, 24 Aug 2002 04:11:21 +0100
A Friend of mine has written a prototype packet sniffer in C#
and I've recently seen code that accesses raw sockets for icmp
ping(I assume - I didnt take much notice - I was looking for
somthing else) I didnt bookmark the url, but it's index by google.
If you want to pick someones brains about it try contacting my
friend about it, his web page is here:

Of course feel free to tell him I sent you :-)
