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.
