I'm very new to networking via cocoa and need to develop a small
port scanner application. The core of it is very simple, is address
1.2.3.4 listening on port X.
Does it have to be a Cocoa API? You should be able to use the Unix
BSD sockets API, which IMHO if you're looking for "short and sweet"
you might as well use.
Doesn't need to be cocoa I guess, as long as it ends with a yes or no,
that should be fine.
If you really want a Cocoa API, then I think NSSocketPort is
probably what you're looking for. Alternatively, use NSStream's
class method "+ getStreamsToHost:port:inputStream:outputStream:".
I'll look at that again but when I did before it seemed to need lots
of support around it (creating pipes and streams, archiving data to
files, etc.) that I was hoping to avoid having to learn about, or find
some kind of simple tutorials on it as much of that is well beyond
what I've been doing thus far.
