Wasn't this one featured on here a little while back ?
This, from the header of flash.c
/* flash.c */
/* This little program is intended to quickly mess up a user's
terminal by issuing a talk request to that person and sending
vt100 escape characters that force the user to logout or kill
his/her xterm in order to regain a sane view of the text.
It the user's message mode is set to off (mesg n) he/she will
be unharmed.
This program is really nasty :-)
Usage: flash user@host
*/
I have the program if you want to see it to formulate a patch or whatever,
(I think a patch exists somewhere but I don't *know* not being a sysadmin
I havent bothered to look it up :)
It really seems to be more nuisance value than anything else, although I
suppose one could conceivably flash root and do something so fast that
itw ouldn't be immediately traceable (although of course noticeable ;)
