"connect: Permission denied" connect system call fails for a simple client server app

[abhayrawat@gmail.com]

Hello all,

My simple client server application using socket is failing, (Client is failing to be precise)
connect system call is failing.
"connect: Permission denied" . My server is listening on port 31512, and client is trying to connect to that port. I am running both client and server on same PC.
I have opened that port also using firewall settings. Do I need to do some thing else also.??

try:

telnet localhost 31512

to see if the port is really open to connections.

BTW, you should use port numbers up to 49152 (but for local purposes, of course there's no problem)

I'm presuming that you wrote the client yourself. When you get the error return from connect(), then

1. What is the exact value of the number returned by the connect() system call itself?
2. Immediately after the errored call to connect(), what is the numerical value of errno?
