TCP/IP connection

I am trying to open the server for TCP/IP connection. My server is RedHat 7.2(postgresql-7.1.3).My question is - Is it necessary to edit etc/rc.d/init.d/postgresql and appened -i and -o options in postgres start script line.

I am trying to acheive this by changing the tcp-connaction flag in postgresql.conf file in data directory. But it does not seem to be working on this platform. But I used to do the same on Solaris and it perfectly worked.

Please suggest/comment!

Thanks and Best Regards,
