Although I am using the -h option on the server, a client still can't connect due to 'connection refused'.

On machine whose ip address is:, I tried
1. startNetworkServer -h
2.startNetworkServer -h
3.startNetworkServer -h

But when trying to connect from, I get the connection refused message.
The firewall on  the  112  machine is set to allow all traffic from and to the 101 machine.

Please advise.
