in thread Socket deadlock doubt in code

Also, my gethostbyaddr function is not working here. It is failing to give me client's hostname. Works fine with same machine as server-client.

The entries in /etc/hosts and /etc/resolv.conf are perfectly fine connected to the same domain.

    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.

      Hi

      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.
