Many servers may have noticed considerable lag with pings rising into the hundreds, if not thousands. Their connection can handle the players, but seemingly randomly, it will start lagging.

If you are confused as to why this is happening, I have the answer. It's a command called "fullupdate". When it is spammed thousands of times in a script, it creates a lag spike that takes approximately 2 seconds to dissipate.

When several people with this script initiate the attack at the same time, it will cause a wave of lag that does not stop. There are groups who have made an art of it, leaving no trace that they ever initiated the command. Most GoldSrc(HL1 engine) servers are vulnerable. (Excluding Counter-Strike) Counter-Strike is NOT vulnerable

The "fullupdate" command is used by some innocent Half-Life features, so I have come up with a solution that does not have false positives.

This plugin fully supports amxbans, so there is no editing required. It has been used by me and a select group of others to protect their servers since early 2008.

At last game update, a cooldown has been added to this command, plugin should be useless.

It works. I tested it on my development server a few days ago.

None of the last few updates in the changelog suggest anything relating to the "fullupdate" command.

[-]May 19, 2009 - Counter-Strike 1.6 Update Released Updates to Counter-Strike 1.6 have been released. The updates will be applied automatically when your Steam client is restarted. The specific changes include: Counter-Strike 1.6 Rolled back recent silent walking exploit fixes as we investigate less impactful ways of preventing the bug Adjusted bomb bounding box to prevent silent plant exploit Fix to eliminate or significantly reduce "flashbugs" Fixed status icons (buy zone, bomb zone, etc) disappearing when starting a recording, or issuing a fullupdate Prevent creating aliases using the same name as existing cvars Rate limit fullupdate and some other commands to prevent spamming Fixed an issue with grenades where they could go into an area and bounce infinitely, causing the server to choke and or crash

Counter-Strike, not HL1 engine.

I HAVE tested this since then. It DOES work on mods other than Counter-Strike. Try it out.
Edited original post to exclude Counter-Strike.

I've tested this with "The Specialists" and "Half-Life 1." However, most mods should be vulnerable.

are you useing no-steam? anyway many big plugins have blocking for fullupdate already included

[stevenlafl]

Which ones? I am also not familiar with "no-steam". I use Steam for every game I own. I play on Steam servers.

Why is it that the entirety of the "The Specialists" mod servers are vulnerable?

I am trying to do the community a favor. If they don't need the plugin, then they don't have to use it. This is for people who need it. I need it, and I have been using it. It has been protecting my server for a year now.

Look steven, they are just trying to see if the plugin is not useful but you already proved it is so no problem.
