Actually i am using "gethostbyname()" to get the hostent and then I am
converting it to a in_addr. Where I have the problem with the IP Address.
Since it returns proper IP Address in some systems and "127.0.0.1" in few
system, I feel I need to configure some network setting.

I'm not sure how you're using inet_ntoa to get the local IP address.
You should use getifaddrs. getifaddrs will return a list of all IP
addresses, not just one. Are you really sure you need to know the
address? When binding, it is best to just by to INADDR_ANY. If you're
sending your address across the wire, you will start to run in to all
sorts of nasty problems with things such as NAT and scoped addresses.
