We've had a few players crash our clients with this glitch, so we installed a script that auto-bans anyone that tries it.

It would be nice if all server operators had your script to ban Vet. Then maybe players would think twice before trying this kind of stuff.rnrnWhat I am saying is would you kindly share?

This plugin is to block the glitch that can cause players to freeze up. It essentially does what D-O's plugin does, in that it blocks the say command, but it allows 1 entry (just in case its an honest mistake, and it takes multiple entries to cause the crash) and provides the option to kick and/or ban (controlled via CVar, default to do both). Why ban without kicking? Just for fun, the player won't know he's banned until he leaves and then tries to reconnect at a later time.nnOne thing to remember, insert the plugin ahead of any other plugin (especially the adminchat.amxx plugin) that might trap the 'say' command so it can filter before it gets to the other plugins.nnAnother point, if you use a word/swear filter, you can block the glitch by simply adding %s to the word list. Then again, ensure your swear filter is listed in your plugins.ini file ahead of most, if not all, other plugins.

Merged the posts from the chat into this thread! Thanks for making it happen!rnrnCheers!

yay lets show everyone how to do it

Posted. The source code is exactly the same as what was submitted above.

just found theres a way to still do the bug even running a plugin to block it...nnnnon-admins can use amx_chat to send a msg to the admins right.. well "amx_chat %s %s%s %s %s%s" still freezes the server, because the msg is sent via client_print and not a say/say_team command.. or something ..and i dont know right now if it also freezes when attempting to use the other amx say commands via console

I don't see where non-admins have default access to the amx_chat command. But they CAN chat with admins using team_say @... and can freeze it that way. That's why I mention to place the plugin ahead of the adminchat.amxx plugin. Is there a method I've overlooked?nnAnd yes, an admin can still cause the freeze using amx_chat, _say, _csay, _psay and _tsay. So you either have to trust your admins or modify the adminchat plugin.nnOf course it would all be simpler if Valve would just fix it.

ahh see how dumb i am.. i took away my admin but never did amx_reloadadmins before i tried it nnnlol silly me

I just tryed this bug on a server, no crash. The chat msg. just showed some boxes, so i guess steam solved it. Just FYI
