Open servers across a range of ports

How do I use "Why Can't I Connect?"

Open a range of limited capacity servers. The servers will try to accept a connection and get the peer IP address and port, it will not try to maintain the connection. Traces will be written for ports that fail to open (the port is possibly in use by another server.) Once open, the server will report any attempt to connect. It will include the peer IP address and port if possible.

Enter the starting port and total ports to open. The maximum number of ports is 1000 in Unix / Linux operating systems, 10,000 in Windows operating systems. The 'Show Trace Message Boxes' check box is a convenience for turning off trace message boxes during Multiple Server sessions (there may be many errors.)
