ICMP (ping) doesn't use ports. I assume you actually want to determine if a host is listening on a TCP or UDP port. Actually, there is no real way to know if a host is listening on a UDP port unless you also know what particular kind of service is associated with that port and know what to look for when a host receives UDP packets on the port in question. So most likely you mean a TCP port. For that, a combination of socket(2) and connect(2) should tell you what you need to know. -- Dave Carrigan d...@rudedog.org Seattle, WA, USA _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
