You've either got another program (or this one is not written correctly), using port 5005, or you're passing the socket creation module an INVALID ARGUMENT, as it's telling you.

Check the syntax of the module.

i checked few things..as per your reply

netstat -a | grep 5005

there is no other proccess using 5005 port and and no other perl scripts running in this server.

and the syntax also right, dont know what mistake iam doing.

What happens if you use actual ip and port numbers instead of variables?

hi,

grail if i give IP means its working, :-)

then i checked my /etc/hosts file..in that instead of 127.0.0.1 | 127.0.o.1 my server provider put entry like this, now i changed the entry, and its now resolving using local host. thanks alot for your help and Tbone.
