in thread Problem with Socket Programming Perl Script

See,
nco_objserv is the process which send the data via port 4500.
So, I need to catch that data. If I kill that process then I won't have any data on that port.
In this scenario how can I achieve this functionality?

    You seem to have it backwards. nco_objserv is listening on that port (see "LISTEN" in netstat output).  That means it won't send any data unless you connect to it as a client. Which is what your first attempt looked like... So, modify that initial code to just don't do accept, but rather simply read from the socket.

        Unlikely, PEBKAC related

        This just means that nco_objserv is having open ("ESTABLISHED") connections to other processes (nco_p_syslog and nco_p_mttrapd presumably, judging by your previous netstat output).

        As servers typically allow to have connections to multiple clients at the same time, you can likely still connect to it.
