By default, the server listens on TCP port 3389.

TCP port 179 is not open.

A random TCP port over 1023 is not open.

Its default is to use TCP port 18181.

This worm has been known to spread on Microsoft-ds or TCP port 445.

Instead, a dedicated monitor application connects to the server via TCP port 3200 and receives information about the state of play.

The choice of the character encoding is defined by the TCP port used to connect to the network but may be changed later on-the-fly.

So I have a way of cryptographically stealthing open TCP ports.

The majority of these clients are hard coded to work on TCP port 70.

When the TCP port is open or filtered, there is no response.
