Jan,

Do Telnet to the port. If you see error, port is not opened. If you don't see error, port is opened.

telnet <ip address> port number

Hi,

on UNIX machine you can use :

netstat -a |grep 443XX

if the output will be similar like this :

tcp 0 0 *.443xx . LISTEN

then that port (443xx) might be open

LISTEN - represents waiting for a connection request from any remote TCP and port.

ESTABLISHED - represents an open connection, data received can be delivered to the user. The normal state for the data transfer phase of the connection.

on WINDOWS machine, there are many port scanner programs that can help you to scan open port.

hope it help you,
