Anti-Ping Mask

What is it?

Anti-ping mask is a plugin that helps prevent players from masking their latency shown to other players on the score board by allowing you to kick them, or ban them from your server. Ping masking is done by using an exploit known with the cl_cmdrate CVAR. Adding a character to the rate value causes the rate to be seen improperly to the server and causes the calculation of the players latency to be corrupted.

How does it work?

Simply put, the plugin queries every players cl_cmdrate upon connecting as well as throughout game play to check for an invalid rate. The plugin makes use the regular expression library to easily find any invalid non-numeric character inside the rate. If an invalid rate is found, the user is either kicked or banned (determined by settings) from the server and a message is displayed to all players informing them of what happened.

CVARs

antipingmask_version - Displays the current version of the plugin.
Default: N/A [Adjusted internally per-version.]
Values: N/A

apm_handler - Determines how Anti-Ping Mask should handle ping masked clients.
Default: 0 (Kick)
Values: 0 kick, 1 ban

apm_banlength - The length in minutes that a player is banned for ping masking.
Default: 30 (minutes)
Values: 0 for permanent, anything above per-minute. (Ex. 60 would be 60 minutes.)

apm_timeinterval - The interval time, in seconds, that the timer should tick at to check for ping masking clients.
Default: 15 (seconds)
Values: Anything above 0, the number is in seconds. (I suggest not going below 10.)

Re: Anti-Ping Mask
 

Why not use a ClientCommand to stop it instead of kicking the client?

ClientCommand(client, "cl_cmdrate 30");

Re: Anti-Ping Mask
 

This being the first plugin I've ever written for SourceMod, I wanted to keep it simple, so I just have it setup to kick currently. In future updates, I can add different things for it to do based on cvar settings and such though.

Re: Anti-Ping Mask
 

Just added this and it is blocked due to one of the semi-recent updates that Valve pushed out that prevents the server from executing commands on clients.

Re: Anti-Ping Mask
 

Why not just set sv_maxcmdrate?

Re: Anti-Ping Mask
 

Awesome! get those 5 pingers. Im all for just kicking them. if they are using bad rates, its probably for a bad reason!
but you know even if they use cl_cmdrate 10 it will mask their ping. you need to check for unacceptably low rates as well.

Re: Anti-Ping Mask
 

I'll be sure to add that in the next version as well to compare against the defaults on the server (min/max) and what the player has. :)

Re: Anti-Ping Mask
 

v1.1.0.0 released. Please see first post for information and new download. (Reuploaded attachment so redownload.)

Re: Anti-Ping Mask
 

I've been looking for one of these plugnis for a while... my server has the following settings on a 66-tick server:

sv_maxupdaterate 67
sv_minupdaterate 66
sv_maxcmdrate 67
sv_mincmdrate 66

yet lots of people seem to be able to still mask their ping i.e. it doesn't fluctuate, it's not just a ping of 5, it also sticks at 12,15 etc.

Re: Anti-Ping Mask
 

well... i have scoreboard latency 5-15 on my own server and i use just rates 25000 100 100.

If you have good connection (10-100mbit/s) and server is near you thats pretty normal i think.
