Bypass Slot Reservation In Counter Strike 1.6

So you are crazy about CS but your local servers are always packed and can not enter the servers due to slot reservations for admins? Don't worry, this guide will provide an insight and step by step details on how to bypass slot reservation in Amx Mod X powered servers. I checked the source code of slot reservation plugin (adminslots.sma) from AMXMODX source and found out that the admin slot plugin was executing a brute-force vulnerable randomized command at the client end. See the line of code below:

format(g_cmdLoopback, 15, "amxres%c%c%c%c", random_num('A', 'Z'), random_num('A', 'Z'), random_num('A', 'Z'), random_num('A', 'Z'))

The bruteforce space is quite small, 4 uppercase characters from A-Z i.e. 26 * 26 * 26 * 26 combination is the maximum amount of search required to find the random part of the command. Hence, the command executed at client end is amxresXXXX where {X: X belongs to [A-Z]}. If there are still slots available for normal players or if the connecting user has slot reservation privilege, he will be able to connect to the server otherwise the server will kick the user. We are not going to bruteforce but we are going to use a memory viewer and editor software that is capable of reading the contents in the memory (RAM).



Basically, we hook into the Counter Strike client process from one of the freely available memory editors. We then connect to the server and get dropped due to the slot reservation message. In the meantime, the server sends the partial-random command.. FYI, these memory viewers make use of kernel APIs such as ReadProcessMemory() to read the memory layout of any process. We search for the initial part of the string which is amxres.

Once we find the unique string sent by server to our client, we use the alias command with amxresXXXX as our alias. For your info, alias provides a mechanism to group different commands to achieve something more useful.

The syntax of alias is: alias "alias_name" "cmd1; cmd2; ...; cmdn" And here we've just created an alias "amxresXXXX" which does nothing since the commands list is missing there.

The tool I've used here is ArtMoney available for download at http://www.artmoney.ru/e_download_se.htm In case, the site goes down, you can get it from here: http://www.4shared.com/file/wm7V4pgv/artmoney740eng.html

Several similar tools exist & are available for free. Some of them are CheatEngine (http://cheatengine.org/downloads.php) and Poke (http://codefromthe70s.org/poke.aspx)

Flash Punisher Plugin For Counter Strike Server [New Release]

Recently I wrote a small AMX Mod X plugin that kills the player who throws flashbangs in counter strike and this post provides the plugin and source code of the plugin for the download.

Why this plugin

Well there are probably few other flash bang punishment plugins already available for download but all I needed was a minimal plugin that would just kill the flashbanger and prevent the effect of the flashbang to other players.

At the first look, the plugin may sound stupid but we play a lot of aa_dima map and few players were continually throwing the flashbangs. There are several maps which are meant to be played by making use of shooting skills that the use of flashbangs. But some people never understand.

I chose to have death as the punishment because that would be the worst punishment any player would expect. And, they will surely be not throwing flashbangs in next rounds.

Download flash_kill.amxx

Or check the Github Repos of Flash Punisher.

Installation is similar to other plugins. Copy the flash_kill.amxx file to cstrike/addons/amxmodx/plugins/ and add a new line "flash_kill.amxx" (without quotes) in the cstrike/addons/amxmodx/configs/plugins.ini.

CVARS:
tg_flashpunish 0 - prevent the killing of player on throwing flashbang.
tg_flashpunish 1 - the plugin shows its effect i.e. the player dies on throwing flashbang.

I hope this plugin becomes useful to some of you guys. :)

AMX MOD X is a very useful plugin not just for the server administration but also for customized gameplay, statistics and fun stuffs. The basic plugins are already there in the AMX MOD X installation but in this post, I'm sharing some of the useful AMX MOD X plugins you can download and put in your server.

Advanced ResetScore
A simple but usefull plugin: players can reset their score and money (controled by a cvar). There's a limit for score reseting and an interval between resets. Players can't reset their score if it's 0 - 0 (already reseted). Admins have a command to reset players score.

This plugins lets you record the demo and take screenshots of your score. Its an useful plugin to have.

Headshot Only Mode
The name of the plugin is self-explanatory. Pretty useful for practising aim in your server.

This plugin shows player speed when your are moving, jumping, climbing a ladder, or in air. Useful for knowing if you are doing bunnyhop right or not :D

[AIOS] (All In One Slap/Slay)
A fun to use plugin with different features for slapping/slaying the players in-game. AIOS is an all in one slap/slap plugin that will meet ALL of you Slap/Slay needs.

Sniper Control
Useful plugin to limit the number of mags per team. It is useful for the pub servers; kind of punishment for AWP campers :D

CSDM
Counter Strike Death Match(CSDM) is a useful amxmodx plugin that adds deathmatch style gameplay to Counter-Strike 1.6.

Aimbot Detection
Think someone in your server is using aimbots to make amazing frags? This plugin can help you find such culprits :)

These were few of the plugins that I've been using in my newly created counter strike server and so far, I've been loving them. I am positive that there are more other useful plugins so throw them as a comment over here. Enjoy fragging :)
