[JDEV] jserver and etherxd

It's beginning to sound like your Linux setup is totally hosed, 
though it could be that tcp_wrappers is setup too tightly (that's 
what's hosts.allow and hosts.deny is for). I'm thinking something 
got hosed because:

1) you had to do something to get localhost (127.0.0.1) to work. 
2) hostname doesn't return anything

Perhaps a fresh install might solve your problem.

Or try setting hosts.allow to:
*:ALL

yes it removes any protection hosts.allow gives you, but if the 
machine is on its own private network, you don't even need 
tcp_wrappers. Plus nothing is working at the moment. Once you 
get something working, then you can retighten the security screws.
