TCP Scope opens a specified listening port on the specified port number.
On each connection a thread is spawned that subsequently makes a TCP connection
to the specified target. The resulting relay thread prints packets traveling
in each direction to the list box display.
The first line of each packet contains information about the connection number
(incremented as each new connection is completed), whether the packets comes
from the client or server, and information about the number of bytes in the
packet. A brief legend showing this line of the packet information is shown
in the top of the window:
All packets and messages are copied to the scrolling log window. This window
can be copied to the paste buffer (using the Copy to Paste Buffer button)
or erased with the Erase button. In addition, a log file be specified. Activating
the log file feature causes all log data to be appended to the specified
file.
Other diagnostic messages, besides packet dumps, are printed to the log screen.
These include announcements of incoming connections, which include the IP
address from which they occur, connections closing messages and a variety
of other error conditions.
