zBlock Version 4.72
Source Engine Server Plugin for the CSS Engine
zBlock was first developed as an addition to the "CSP" server plugin, at this time VALVe had accidentally let a convariable slip that would allow players to "wallhack".
"CSP" (CAL Server Plugin) was a server plugin
that enforced certain cvars that could either be exploited or created an
unbalanced/unfair playing field.
Another feature of zBlock was to make CSP more difficult to bypass, however not too long after release, we determined that instead of making CSP more difficult to bypass, we should instead take on board the functions CSP had due to the significant ease at which is was bypassed.
zBlock is now one of the most used CS Source server plugins all around the world, enforced in the majority of competitive leagues around the world it's become a plugin you can't imagine CS Source without any more.
Remove any previous zBlock files from older versions (zblock*.dll/zblock*.so/zblock*.vdf).
Copy the "addons" folder and its contents into your game-servers mod directory, i.e. "ROOT/css/cstrike/". This will create a new folder "addons" and copy the plugin files onto the server so that next time it restarts the plugin shall be loaded.
Restart the server.
-A Windows server requires only the "zblock.dll" and "zblock.vdf" in the addons directory, whereas the Linux server requires only the "zblock.so" and "zblock.vdf" files.
-If you are unsure which operating system your server uses: consult your game-server-provider.
-Please make sure your server is up-to-date using the 'hldsupdatetool' (-verify_all) otherwise the plugin might not be able to load for reasons of server security.
-Loading the zBlock Plugin via rcon plugin_load is not possible due to security reasons.
Enabling or Disabling zBlock
Note: It is recommended that any server config changes affecting zBlock are made in the "server.cfg" file on your server - and not the "autoexec.cfg".
To Enable/Disable zBlock the CVAR "zb_active" is provided (accessible via rcon or by addition to the server.cfg file).
Set this to '0' to disable the plugin, and use '1' to re-active.
Example: From your client console type:
rcon zb_active 0
rcon zb_active 1
*It is highly recommended that zBlock be kept
running at all times (for most competitive and league games this will be a

Is a public cvar which is queryable from
connected clients and also via server monitoring tools such as HLSW.
We highly recommend you stay clear of servers where zb_status has a value greater than 1, this indicates a problem with the configuration of the server.
A description of the current zb_status value is shown in the welcome message to connecting clients (console) and also by using the command "zb_status".
A Note About "sv_pure"
zBlock 4 will only allow sv_pure values 1 or 2 whilst the plugin is active and will automatically change the map (issuing a kick message to all connected clients) whenever its value is changed - this is to allow the new value to take effect correctly.
Note: All league servers should have the setting "sv_pure 2" in their server.cfg's.
A further change in zBlock v4 is that sv_consistency is forced to 1 whilst zBlock is active.
When sv_pure takes a value of 1 or 2 it enforces connecting players to use some default content ("sv_pure 2" being more restrictive than 1), this can affect some sound modifications such as the "quake sounds pack" or "admin sounds" from being played and also older player skins from being used.
We recommend that server operators who wish to use this modified content use "sv_pure 1" in their server.cfg's and enforce a whitelist.
Details on how to configure your servers whitelist is available here:
(You will need to allow the custom content from disk)
Map Restarts Triggered by the zBlock
On changing the value of certain server cvars when running the zBlock plugin your server will automatically restart the current map (kicking all players to give the reason for the map change), this is done to ensure a level playing field on your server and also for ease of use to server administrators.
A change in the following cvars will trigger a map restart:
zb_active (on only)
sv_cheats (off from on)
CAUTION: Be careful that you do not make contradicting references to these cvar values in your "server.cfg" (ran automatically on map loads) as this will cause your server to repeatedly reload the map.
Warmode is a new concept found in zBlock from version 4.5,
this is designed to give a distinction in the plugins configuration between a
public and a private/competition/war-server.
As such when zb_warmode is disabled the settings are not as strict. We turn off things such as map consistency, the super-boost fix, warnings and welcome messages.
With warmode on we enable the match functionality and lock down a lot of the server cvars, disable certain features which are unsuitable for competitive play and also only allow pausing during round-end and freeze-time.
We expect further features to be tied in with the functionality of the cvar in the future.
Plugin Not Loading?
If the plugin does not seem to be loading, here are some tips for troubleshooting the issue.
Restart the server and join and type "rcon plugin_print", is zBlock listed in
the list of plugins?
-If it is, then maybe "zb_active" is set to '0'.
Load the plugin manually using:
rcon plugin_load "addons/zblock"
View the message which appears, this should help you locate the issue.
-Note: This action will not actually allow you to load the plugin, but should indicate the problem.
Stop your server.
Remove all zBlock files from your "addons/" directory.
Make sure the server is up-to-date using the hldsupdatetool (use the "-verify_all" command line option when updating to check for corrupt files).
Re-install zBlock as per the instructions in this text file. (Make sure your version of zBlock is also the latest).
Restart the server.
Contact your server administrator/GSP staff.
