Hi Utkarsh, neither an error message I get from pvserver. It just keep waiting for connection until exit due to time out... the client stays there with the "waiting for server connection" screen open and nothing happens.
I'm not familiar with telnet commands but tried the following: telnet> open my.ip.external.address 11111 Trying my.ip.external.address... and it just hangs trying to connect. The client in this test is a Macbook running Lion. I've tried with the firewall open and closed as well. Any more hints? Renato.
