Re: dos on quake1 servers

The bug described below has been fixed in ProQuake, the author
J.P. Grossman has released ProQuake 1.02, this version also introduces a
pq_draqfps console variable.

ID was checking for a message and if the packet size was zero then it was
an error, then preventing any more connections.  Yet another ID Software
bug. :)

Again, this has only been fixed in ProQuake as far as I know.

hallo,

sorry if it is a known thing...

running the following command on a quake1 server's ip address

# nmap -sU -p 26000 xxx.xxx.xxx.xxx

in most cases will "crash" the quake1 server program.
attempts to connect to or query it with qstat will result in "no
response" message.

# nmap --version --> nmap V. 2.3BETA14

quake2 or quake3 servers were not tested

bye,
