for those of you who have had problems with being "flash"ed,
here's a patch to ntalkd that will solve this problem.  apply
with "patch < <this file>" in the /usr/src/libexec/ntalkd
directory.

[ this has been send-pr'ed also ]

.mrg.

ps, for those who don't know what flash does, it basically
send's a bogus username in a talk request with nasty chars in
it.  things like vt100 reset, and other nasties to make life
unpleasant.
