Subject: Quake client killer
Not sure if this is news but I have found a way to take down remote quake
clients (Win95) very simply with little evidence left behind. Basicly you
write a few hundred k of data to one of the udp listening ports and
quake dies and up pops a little dialog box saying:
A network error has occured
I found this over the weekend while admining a small LAN party were
everything worked too well so I got bored hence tried out of curiousity
this:
dd if=/dev/zero | nc -u client 27501
I haven't tried this on NT / Linux / Other clients or games, it appers
on Win98 and Win95 and has no effect on servers that I can tell, thou
nothing is logged.
I wonder if the effect only appers if done from the server because I
didn't have time to try much out and the normal connection for quake is
client:27001 -> server:27500
And I was working on the server.
