Using a Packet Sniffer to Kick Players in MW2 as Host

[Mythiasis]

I'm looking for some good discussion and instruction on how to use a packet sniffer to kick specific players when hosting a MW2 round.

Since VAC is fail and cheaters are still running rampant; I'm looking for a way to curb the issue when I am host. And with my 10mg up speed, I am host a lot.

So far, I've heard of Wireshark and Commview as tools to use and even have some instruction on editing and looping a packet; but wanted to discuss what everyone else thinks about this. It's a hard topic because in the wrongs hands, griefers will just go nuts kicking players or entire rounds for their own kicks, or kicking good players who they think are hacking. I'm wanting to use it to remove obviously cheating players - cheating as in not high-scoring players, but players that show killcams where they are spinning 180+ degrees to snap headshots through walls across the map kinda cheater.

If you would like to discuss this in private; please PM me. I'm not quite comfortable with it as a public discussion for reasons already mentioned.

But, it has to start somewhere if I'm going to get any help.

If anything, point me in the right direction or forum where this can be discussed in a PM and let the Mod lock or remove this thread.

Thanks!

I know this is a valid topic, and don't want to derail it too much, but if you're after competitive MP experience w/admin abilities then Modern Warfare 2 will never be that game. Though good luck to you on trying to implement a few features that are desperately needed to make it even worthwhile trying.

Look into kicking in Warcraft 3, they actually do the same thing in custom games. It is as easy as simply blocking their IP in a firewall I believe.

That works, yes; but I need to know which IP is the right one. To do that, I need to send a fat packet and see whose latency spikes. Then I know I have the right person and can filter out the IP.

There are probably easier ways of going about that. Plus I doubt anything that you could upload would directly make them lag at all. due to the fact that the average upload speed is just 1/10 the average down speed.

You don't need to lag them, just spike the latency enough to notice it on the player list. A script to ping their IP about 25 times should do it.

Don't know why this double posted.

Just a quick comment, it surprises me that MW2 doesnt have a steam style "status" console command to spit out ips or steam ids (since it seems to utilize steamworks to a decent degree)

At the very least they should have a ban command that saves it to your computer based on IP or atleast keeps working for the game.

It's Modern Warfare 2. You would expect a lot of things that it does not have.

And all is for naught; though you may be the host for a game, it is not direct p2p. IWNet sends you all the packets from the other players, so you are only getting the one connection from IWNet and not each player. Which is why the host has such a major advantage in the game. More fail for IW.

So now I'm waiting on Bad Company 2.

Mmm... i reckon it'd be more fun to make a script that always makes you the host, then another script that creates uber-lag for everyone else and then kill everyone and get 200-0 and then laugh and set your name as "IW.NET SUCKS" or whatever.

That's probably easier than trying to ban 1 person based on their IP.

If you are truly host, kicking players is very easy. All you would need is CommView, a firewall program, and (preferably) another computer with two network cards, so you wouldn't have to alt/tab so much.

1.) Use CommView to get the IP addresses.
2.) Take an IP (any IP you wish).
3.) Add it to your firewall's blocked IP listings.
4.) Raise your firewall level.
5.) (Quickly) See whose ping has dropped significantly.
6.) Keep the firewall in place until they're gone, or if it's the wrong player, back out, note their IP address, and go again.

Simple as that. Assuming it's giving you a straight host and not a run-around.

Ya.. as easy as hitting the Kick button, like in proper MP games.

Against my better judgement, i bought a copy to play CO-OP with a buddy. Though, the more i use the MP/matchmaking system and it's ridiculously retarded, the more i hate it. I cun't believe that THAT is what the console players have been putting up with all these years. I get pissed off at it on a regular basis. "Well that's stupid", "wtf?", heavy sighs, and general loathing now accompany my MW2 playing.

But once the CO-OP actually starts, it's pretty fun. even with the lack of a lean.

And sincere apologies to for comparing retards to MW2. It's not fair to them. MW2 retardation was actually planned. Scary stuff. And with the insane sales figures they're claiming, it worries me for the future of PC gaming. BC2 is looking more and more as what MW2 shoudl have been.


EDIT: sorry, not trying to yoink the topic, i just wanted to bitch.

Read the thread. That won't work.

And what about actually playing the game lol, sounds like more work than fun.
