Disconnect Reason

.: v0.6

Description

This plugin notifies players via chat and console the reason that a player has disconnected (ie. Timed out, Client sent 'drop', Kicked). The standard console message notifying of a player disconnect will not be shown when the plugin is enabled. I've also eliminated the cvars found in the previous release that controlled notification types and notification methods; all types of disconnects are displayed in both chat and console. There is also a forward which allows you to utilize disconnect reasons in your own plugins 'client_disconnect_reason( id , drCode , szReason[] )', see below example. The forward remains active regardless of the dr_enabled cvar value which will only control chat\console message. Made by request.

CVars

• dr_enabled <0/1> - Chat\console notification enabled\disabled status.
  • Default: 1 (0=disabled, 1=enabled)

Forwards

• client_disconnect_reason( id , drCode , const szReason[] ) - Forward for client_disconnect with reason.
  • id - Player id
  • drCode - Disconnect reason code
    • DR_TIMEDOUT
    • DR_DROPPED
    • DR_KICKED
    • DR_LEVELCHANGE
    • DR_OTHER
  • szReason - Disconnect reason in text form: "Timed out", "Client sent 'drop'", "Kicked", "Dropping fakeclient on level change".

Disconnect Reason Codes

PHP Code:

enum ReasonCodes
{
    DR_TIMEDOUT,
    DR_DROPPED,
    DR_KICKED,
    DR_LEVELCHANGE,
    DR_OTHER
} 


Modules

• Orpheu

Installation

• Place compiled (.amxx) file in plugins directory as with any other plugin.
• Place the SV_DropClient file (found in signatures.zip) in amxmodx\configs\orpheu\functions.
• For forward to work in your plugin(s), you must have this plugin running (do not #include it).

Example Plugin

PHP Code:

#include <amxmodx>

new const Version[] = "0.1";

enum ReasonCodes
{
    DR_TIMEDOUT,
    DR_DROPPED,
    DR_KICKED,
    DR_LEVELCHANGE,
    DR_OTHER
}

public plugin_init() 
{
    register_plugin( "Disconnect Reason Example" , Version , "bugsy" );
}

public client_disconnect_reason( id , ReasonCodes:drReason , const szReason[] )
{
    //Display info
    server_print( "id=%d ReasonCode=%d ReasonText=^"%s^"" , id , drReason , szReason );
    
    switch ( drReason )
    {
        case DR_TIMEDOUT: server_print( "Poor guy timed out" );
        case DR_DROPPED: server_print( "Ughh, another player left my server :(" );
        case DR_KICKED: server_print( "Player kicked, toodaloo!" );
        case DR_LEVELCHANGE: server_print( "Server changed map, he didnt leave" );
        case DR_OTHER: server_print( "hmm, why did he get disconnected?" );
    }
} 


Changelog:

• v0.6
  • Added 'Dropping fakeclient on level change' disconnect reason.
• v0.5
  • Added client_disconnect_reason forward for hooking client_disconnect with reason.
• v0.4
  • Removed Sys_Printf hook since I'm pretty sure it is only used for printing to server console which nobody sees anyway so it's pointless to block. I initially assumed it printed to both server and client consoles.
  • Added block for message #Game_disconnected to prevent players from seeing "Name has left the game" in console.
  • Removed post hook for SV_DropClient since it was not needed.
    • v0.4a
      • Minor code cleanup
• v0.3
  • Improved signature used for SV_DropClient
  • Removed cvars for controlling type and method, all disconnect types are notified in both chat and console.
  • Added Sys_Printf hook to block the default disconnect message in console.
• v0.2
  • Added condition to check that a real player is disconnecting. xPaw reported that a notification appeared with the server name (id=0).
  • Changed chat notification from messaging all players individually to a single message to all.
• v0.1
  • Initial release

Wow, cool

[xPaw]

Why not use MSG_BROADCAST for chat message?

[Bugsy]

I copied that function from my aimbot detect plugin which notifies on a per player basis. I will modify when I get home.

Good job.

I have to update my tutorial but a better rule would be : all can be changed except the first byte and local vars (e*x).

So you get something like :

[0x55,0x8B,"*",0x81,"*","*","*","*","*",0x8B,0x4D,"*",0x53,0x56,0x8D,0x45,"*",0x57,0x50,0x51]

Nice plugin!

[Bugsy]

I didn't understand the signature mask part very well. I tried to do exactly what was done in the sigscanning tut and your (Arkshine) tut, but for the most post I was just experimenting and it worked. A tutorial dedicated to making signatures/masks from a newbie perspective would be very useful. I have no experience on the subject.

[dark_style]

I have an idea for you. What about to add the reason when mp_autokick is set to 1 and the player get kicked by it?

[Arkshine]

If it can help better :

55                   push    ebp
8B EC                mov     ebp, esp
81 EC 00 06 00 00    sub     esp, 600h
8B 4D 10             mov     ecx, [ebp+Format]
53                   push    ebx
56                   push    esi
8D 45 14             lea     eax, [ebp+Args]
57                   push    edi
50                   push    eax            
51                   push    ecx

- Blue -> You keep always the first byte, and if there is only one ignore what you see after. (like 'ebp' in the first line)
- Green -> When you see e*x is used, you can keep the byte

Others = could be changed.
