so perhaps the most likely explanation is that Tracy is getting port-scans 
or automated hacking attempts (which might well do rude things to the telnet 
protocol). Of course, my answer would be to convert the physical 3000 into a 
virtual MPE V machine using SIMH so you're not dependent on the ancient 3000 
TCP/IP stack :) G.

You could write a port handler for Telnet, as a passthru to the real telnet;
then report and handle it your way - but not up on telnet protocal, so not 
sure what you could do.


I have a Quote of the Day service that runs on (partial SERVICES.NET.SYS:
   21     qotd          17/tcp                 # KDM Quote of the Day
   22     qotd          17/udp                 # KDM
   26     telnet    1xxx/tcp

telnet 3kranger.dyndns.org 1717

I log time of day, incoming ip, what quote they got.
