You have to connect to it. Unfortunately, neither NSSocketPort nor NSConnection attempt to connect until you send data, so with those, you have no way of immediately knowing that anything is actually listening. The best way is to get down a level and use socket(2) and friends. -- Dave Carrigan d...@openshut.net Seattle, WA, USA _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
