sockspy [http://www.neosoft.com/tcl/ftparchive/sorted/net/sockspy-1.0]
"watch[[es]] the conversation of a Tcp client and server",
according to its quite readable README
[http://www.neosoft.com/tcl/ftparchive/sorted/net/sockspy-1.0/1.0/sockspy-1.0.README].
Although "not a
replacement for heavy duty tools such as 'tcpdump' and other passive
packet sniffers" (Ethereal [http://www.ethereal.com/], ...), it's easy to install, configure, and launch, and

----
Version 2.0 of sockspy is available on sourceforge at
[http://sockspy.sourceforge.net/sockspy.html].

Among the new features are:
   * reorganized GUI to use one pane and different colors to indicate client, server and meta data
   * can be run as a command-line (tcl not tk) application.  Before 2.0, sockspy was inherently Tk
   * you can stop, start and change the socket forwarding configuration from within the application
