That's was the problem. I tested with nil on GNUstep, it works fine now.

This would make sense.

Why not check if the host name is a local host name. If so, ignore  
it. If not, raise an exception telling the default connection cannot  
be used for inter-machines communication, a connection relying on  
NSSocketPortNameServer must be created.
