If it helps, I am running the program from a telnet session. The Debian
box does not have a monitor or keyboard attached to it normally since its
only use is to route packets and answer DNS querries. I am running the
standard kernal for R0.93 recompiled with firewalling and ip forwarding and
the latest driver for the 3COM 3C509B network card (the one that Linux uses
- found on a Linux WWW page).
Thank you for your time and attention.
