Socket Bindind Issues!!!

Now what Language did you write this Socket w/ {PERL , C++ , etc};

Is the Program really listening? - use netstat.

What protocol is the program using - TCP , UDP?

See is you can telnet the port and get a possible socket hang - that indicates that something is listening.

Test locally on the running server before remotely /!\.
