I'm assuming that these are Linux hosts. If so, errno 111 is
"connection refused" possibly meaning that there is still some
firewall active or the wrong interface is being used to establish
connections between these machines.
Can you send the output of "ifconfig" (might be /sbin/ifconfig on
your machine?) from both machines?

I did disable the firewall on both machines but I still get that
error message.
Thanks,
