FuhQuake

flashrox · Guest

Hello,

I'm Flash, administrator of the quakeworld brazillian servers,
I have noticed a great number of players abusing of the altered
option of opengl32. Is there a way to make a version of fuhquake
with checking of DLLs or something like that,
cause I can't stand seeing this people cheating in the game.

Waiting for you answer

Flash

this a screen of wall in fuhquake

it's impossible to check for modified versions of opengl32.dll by fuhquake really. every video card uses a different one, and there'd be thousands overall.

that is correct, but those dll's have nothing to do with wallhack. only opengl32.dll matters.

fuh, what about remove the /scr_allowsnap and set 1 by default,
so server admins can snapshot, and may catch some cheaters..
or make defaults opengl32.dll to use with fuhquake,
u download the opengl32.dll for u driver card from the fuhquake site and fuhquake just does a check if this dll is the same from the site...

like a f_dll
player: voodoo 2 - dll is security!
player1: geforce 2 - dll is security! (i think there's no dll for gf cards btw)
player2: geforce 2 - dll isnt security!

just ideas

scr_allowsnap sucks, this is the only way that admins have to rape those opengl.dll hax0rs.

I agree with guest

Server side screenshot taking is a really bad idea imo (zoid planned it for qw2.4). First of all you get a huge fps lag when the shot is taken (writing to hd, png/jpg compresion) and then you have to upload to the server which will kill all non-ethernet connections making it unplayable. I doubt the threat of sshots will scare away many cheaters and it just ruins the game for innocent players.

If opengl.dll cheating is so widespread on your servers maybe all gl clients should be banned (software only).

Well, you could ask gl what it thinks it is and print that along with a crc.
If you get a crc that you've not seen before, get a snap. You need some sort of admin for it, with a big long list of em.

Remember to check for dlls according to the path, and then to check for any OS kernel hacks... You don't have to code anything in to your security dll. It shouldn't be too hard to knock up something useable if you are prepared for admins to work individually.

But it will give away what sort of card you've got, and some people may object to that.

uh hangtime?

maybe if your computer is from the 60's...

it takes about as much fps from the modern computer, to write and lossly compress a 1600x1200 image, as it does in generating the particles in a single quake explosion -- probably even less.

and sending a 50-100 kb file over even dialup -- a one time affair, is no biggie. it certainly wont "ruin" a game for innocent people -- they will be for it, expecially if it is the only way to find out about cheaters.

as to banning all gl client.. in qw maybe this is possible, but most games are gl-only...

and even in qw, i dont think many people will be happy for this banning "solution"

I was thinking if you Draw a large white quad over the screen at the front, then draw some other stuff behind it.

On a normal opengl screen the whole thing will be white, on one with a wall hack the other stuff will show through.

So if you use some glReadPixels or what ever you can test if they are white and as they should be or if they are some other colour. If they aren't white then the client quits.
