Subject Re: [IB-Java] Interclient and Localhost on Suse 7.3

What happens if you try to connect to the IP of your NIC instead of localhost

Try telnet localhost 3060 and telnet IP-NIC 3060

If interserver is running on those interfaces, you should see either something about interserver or interclient written in the telnet session. Are you starting interserver with inetd / tcpd ?
