All ports are open, but you really need some service to listen that port.

Thank you . So why 'telnet 172.16.17.132 4965' cannot get through ?

As Eero said, you need to make sure something is listening on that port.

Try: netstat -ant and look for:

Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:4965 0.0.0.0:* LISTEN

or pipe it to grep if the server is busy (netstat -ant | grep 4965)
