Default [Release] AnthChecker v1.37

Code:
##############################################################################
#                            AnthChecker v1.37                               #
#                            by )°DoE°(-AnthraX                              #
##############################################################################

1) What is it?
--------------

AnthChecker is an advanced unrealscript-based cross-platform packagechecker.

|| Please take a few minutes to read this document, it will spare you and me a lot
|| of trouble.

2) What does it do?
-------------------

AnthChecker will validate every client (including clients that run Linux/MacOS)
after they enter the server. Depending on the server's settings AnthChecker will:
    * Perform selfchecks to prevent clients from redirecting/bypassing the checking routines
    * Perform CRC (Type 1) checks on files that should be identical on the server and on the client (files like UTPure.u)
    * Perform CRC (Type 2) checks to identify the client's skintextures and kick if they're hacked
    * Perform MD5 checks to identify the client's renderdevice and kick if it's hacked
    * Perform MD5 checks to identify the client's libraries and kick if they're hacked
    * Scan for disallowed files

3) Installation
---------------

To install AnthChecker on your server:

1. Unzip the contents of this zip package in your server's system folder. 

2. Open your server's unrealtournament.ini file and find the line that reads "[Engine.GameEngine]".

3. Add these lines under it:

    ServerActors=AnthCheckerS_v137.ACActor
    ServerPackages=AnthCheckerC_v137
    
4. Move to the end of your UT.ini file and add these lines 
   (you can find the explanation of the settings under 4) Settings):    
    
    [AnthCheckerS_v137.ACActor]
    bKickUnknownRenderer=true
    bKickUnknownLibrary=true
    bKickUnknownSound=true
    bKickUnknownSkin=true
    bBroadCastJoin=true
    bBroadCastIPs=false
    bExternalNotify=false
    bSelfCheck=true
    bPureCheck=true
    bEUTCheck=false
    bSkinCheck=true
    bSoundCheck=true
    bShowConsoleMessages=true
    TimeOut=30
    CheckDelay=3.0
    bReportCheats=True
    bReceiveUpdates=True
    Packages[0]=
    Packages[1]=
    Packages[2]=
    Packages[3]=
    Packages[4]=
    Packages[5]=
    Packages[6]=
    Packages[7]=
    Packages[8]=
    Packages[9]=
    bExternalLogs=true
    LogPrefix=
    LogPath=
    ACLinkMode=2
    ACDelay=5
    
5. Restart your server

4) Settings
-----------

You can easily change the AnthChecker settings by opening your server's ini file and changing
the lines you added at the end.

    bKickUnknownRenderer : set to false if you don't want to kick clients with an unknown renderdevice
    bKickUnknownLibrary  : set to false if you don't want to kick clients with unknown libraries
    bKickUnknownSound    : set to false if you don't want to kick clients with unknown soundpackages
    bKickUnknownSkin     : set to false if you don't want to kick clients with unknown skinpackages
    bBroadCastJoin       : set to false if you don't want to broadcast every client's nickname/renderdevice/operating system after the validation
    bBroadCastIPs        : set to true if you want to add the client's IP's to the bBroadCastJoin messages
    bExternalNotify      : set to true if you want AnthChecker to send playerjoin reports to other mods (requires compatible mod)
    bSelfCheck           : set to false if you don't want to perform a crc check on the anthchecker client package
    bPureCheck           : set to false if you don't want to perform a crc check on the utpure package
    bEUTCheck            : set to true if you want to perform a crc check on the EUT package
    bSkinCheck           : set to false if you don't want to perform crc checks on the skintextures
    bSoundCheck          : set to false if you don't want to perform a crc check on the female2voice package
    bShowConsoleMessages : set to false if you don't want to display what's going on in the client's console
    bReceiveUpdates      : set to false if you don't want to receive info about new renderdevices from the AnthChecker masterserver
    bReportCheats        : set to false if you don't want AnthChecker to report cheating attempts to the AnthChecker masterserver
    TimeOut              : ammount of time the client gets to finish the checks (in seconds)
    CheckDelay           : ammount of time between the playerjoin and the start of the checks (in seconds)
    Packages[x]          : you can manually add files to crc (type 1) check here
                           syntax: <file extension>,<filename>,<packagepercent (1-255)> (*)
    bExternalLogs        : set to false if you don't want to log AnthChecker's kicks to external files
    LogPrefix            : Prefix of the external logfiles (default: [AC])
    LogPath              : The path in which the external logfiles are stored (default: ../Logs/)
    ACLinkMode           : set to 1 if you want to delay the updatescheck
    ACDelay              : ammount of time before the updatescheck begins (in seconds, only needed if ACLinkMode=1)
 
 !! Important !!: Due to the limitations of the unreal engine, you're not advised to manually add files.
 		  If you do decide to do so, use a small packagepercent, UT will usually crash after crc checking
 		  10Mb of data.
    			  
 (*) if for example you want to perform a crc type 1 check on the 10 first bytes of every 255-byte block of CTF-Gauntlet.unr, 
 you'd have to add "unr,CTF-Gauntlet,10" (without the quotes)

I'd assume the hash for UTDC17c isn't in there yet?

Maybe it's on the web, and you have AutoUpdates set to off?

Just ideas

Not really

[AnthCheckerS_v137.ACActor]
bKickUnknownRenderer=true
bKickUnknownLibrary=true
bKickUnknownSound=true
bKickUnknownSkin=true
bBroadCastJoin=true
bBroadCastIPs=false
bExternalNotify=false
bSelfCheck=true
bPureCheck=true
bEUTCheck=true
bSkinCheck=true
bSoundCheck=true
bShowConsoleMessages=true
TimeOut=30
CheckDelay=3.0
bReportCheats=True
bReceiveUpdates=True

And I tried it before with UTDC17c. And we had like dozens of other players.

Just plain weird

Hi,
I have upgraded from 1.34 to 1.37.
When I try to enter in my server, this is what I obtain:

http://www.kw-clan.com/images/error.jpg

In my log there is that about this error:

###################################
### -------------------------------------------------------------

###################################

With 1.34 version and:

bReceiveUpdates=False

I had no problem.
CRC files checking made by AnthChecker are the same from 1.34 to 1.37.

Thanks in advance.

this happens when you do a CRC check on a file that's too big

1. Erase anything starting with "Female2" in your UT Directory.

2. Then Connect to my Server and let my server give you the correct ones.

My Server IP is 67.19.181.52

3. Clean your UT Cache.

4. Try other Servers again.



Also, try not to demand things next time, poeple are less inclined to help people that demand something in which they have no experience in.
