gethostbyname relies on a functioning DNS system. Make sure things like nslookup and traceroute work properly. The other place you might be going wrong is that in a scalar context, gethostbyname returns the packed ip address, though I'm not sure why you're looking up the hostname from a hostname to begin with.

As for the printing issue, I suspect that you are Suffering from Buffering.

Update: oops, gethostbyname is irrelevant here but the DNS still needs to work.

    I am using gethostbyaddr here at server's code to get the client's hostname. You can check the code in the first thread for the procedure.

    I am doing this to find out which client has connected to the server.

    I am tracking the issue for the DNS right now, since the current setup is between two VM machines.

      Sorry, my mistake. I would think the problem is your DNS set up since your gethostbyaddr code works fine here.
