The behaviour of "cannot bind to that socket" could be correct. On a 
single machine there can be only one process listening on a given port. 
So, if an application binds to a port, no other applications (neither 
another instance of the same) can bind to that port again.
This can be possible if the machine has more than one interface, say 
"127.0.0.1" and "192.168.1.1". Then two programs can listen on the same 
port, but on different interfaces.
