Hello i'am trying to learn little more about HL1 coding but it's really hard without some basic examples and tutorials.

My first project is based on thread for flood that i see here. I start searching for common projects and found one-two-three but all for SourceMOD. Then i go MAD and decide to try to reverse it in metamod code. But nothing happen, becouse there are functions that the plugin need but are not really there and cannot build the project. ( I think so... )
Original plugin for SM is here

This is my code for now. Please help me to fix & run it.

#include "amxxmodule.h"
#include "protect_amxx.h"
#include "netadr.h"
// ===============================================================================================================
#define fClearTrieTime			12.4
#define iConnectionBanCount		6
#define iIPLength				17
// new Handle:g_hTrie;
// ===============================================================================================================
void OnMetaAttach() { printf("\n   Enter on Meta\n\n"); } // g_hTrie = CreateTrie();
void OnMetaDetach() { printf("\n   Exit on Meta\n\n"); }
// ===============================================================================================================
BOOL ClientConnect(edict_t *pEntity, const char *pszAddress, char szRejectReason[128]) {
	// ==================================
	int iPlayer = ENTINDEX(pEntity);

	char sIP[IPLEN+1], *p;
	const char *playerIP = netadr_t->ip[IPLEN+1]
	
	// ==================================
	if (IsFakeClient(client)) {
		return true; // Why would we want to even check these clients?
	}
	decl String:sIP[iIPLength];
	if (!GetClientIP(client, sIP, sizeof(sIP))) {
		return true; // We don't want to reject them if we can't get their IP... Although this should never happen.
	}
	// ==================================
    if (!GetTrieValue(g_hTrie, sIP, iConnectionCount))
	{
		new Handle:hPack = INVALID_HANDLE;
		CreateDataTimer(fClearTrieTime, ClearValueFromTrie, hPack, TIMER_DATA_HNDL_CLOSE);
		WritePackString(hPack, sIP);
		ResetPack(hPack);
		
		SetTrieValue(g_hTrie, sIP, 0);
		return true; // We don't want to call the below code if this trap works.
	}
	
	if (iConnectionCount == iConnectionBanCount)
	{
		PrintToChatAll("\x04[CFP]\x03 Banning %N (%s) for flooding connections to the server.", client, sIP);
		LogToGame("[CFP] Banning %N (%s) for flooding connections to the server.", client, sIP);
		strcopy(rejectmsg, maxlen, "Banned for Connection Flooding.");
		BanClient(client, 0, BANFLAG_IP, "Connection Flooding.", "Banned for Connection Flooding.", "sm_connectflood_protection");
		ServerCommand("sm_banip \"%s\" 0 \"Connection Flooding.\"", sIP);
		return false;
	}
	// ==================================
	SetTrieValue(g_hTrie, sIP, (iConnectionCount + 1));
    RETURN_META_VALUE(MRES_IGNORED, true);
	// ==================================
}

I think that an efficient fix to this issue would be to run a steam server.

where is this header file protect_amxx.h ?

[xakintosh]

Here it is.

#ifndef _INCLUDE_PROTECT_AMXX_H
#define _INCLUDE_PROTECT_AMXX_H

// SOME CUSTOM DEFFINITIONS!

#endif //_INCLUDE_PROTECT_AMXX_H

[K.K.Lv]

this is the amxx code, un-test:

#include <amxmodx>
#include <fakemeta>

#define PLUGIN_NAME "Connnection Protection"
#define PLUGIN_VERSION  "0.1"

#define fClearTrieTime      12.4
#define iConnectionBanCount  6

new Trie:ghTrie;

public plugin_init( )
{
    register_plugin( PLUGIN_NAME , PLUGIN_VERSION , "LittleKu-Lv" );
    
    register_cvar( "amx_cfp_version" , PLUGIN_VERSION , FCVAR_SPONLY | FCVAR_SERVER );
    
    register_forward( FM_ClientConnect , "fwClientConnectPost" , true );
    
    ghTrie = TrieCreate();
}

public fwClientConnectPost( id , const szName[] , const szAddress[] , const szRejectReason[ 128 ] )
{
    if ( pev( id , pev_flags ) & FL_FAKECLIENT )
    {
        return FMRES_IGNORED;
    }
    
    if ( szAddress[ 0 ] == 0 )
    {
        return FMRES_IGNORED;
    }
    
    static iConnectionCount;
    static params[ 32 ];
    
    if ( !TrieGetCell( ghTrie , szAddress , iConnectionCount ) )
    {
        copy( params , 31 , szAddress );
        set_task( fClearTrieTime , "ClearValueFromTrie" , 0 , params , 32 );
        
        TrieSetCell( ghTrie , szAddress, 0 );
        return FMRES_IGNORED;
    }
    
    if ( iConnectionCount == iConnectionBanCount )
    {
        static iUserId;
        iUserId = get_user_userid( id );
        server_cmd( "kick #%d;addip 0 %s;writeip" , iUserId , szAddress );
        return FMRES_IGNORED;
    }
    
    TrieSetCell( ghTrie , szAddress , ( iConnectionCount + 1 ) );
    return FMRES_IGNORED;
}

public ClearValueFromTrie( params[] )
{
    static szAddress[ 32 ];
    
    copy( szAddress, 31, params );
    
    TrieDeleteKey( ghTrie , szAddress );
    
    return PLUGIN_CONTINUE;
}

public plugin_end()
{
    TrieClear( ghTrie );
}

there is already plugin made by 6a6kin, you can find it on his SVN: https://github.com/6a6kin/FloodBlocker/
K.K.Lv, fake players doesnt appear on client_connect, u can catch them on ClientUserInfoChanged, but without IP.
Use metamod plugin from SVN.

6a6kin is awesome.

[xakintosh]

I talk with 6a6kin on russian amxx forum and i got it few days back.
I also success to compile it and i'am using it now.
Thanks to 6a6kin! He's AWESOME!!!!

But still i need "Connnection Protection" for metamod plugin, if is possible. I just don't have time now to take a close look in hlsdk and review my options.

[K.K.Lv]

nice link GordonFreeman,and thanks for your tips

i don't understand how to compile that plugin

[xakintosh]

Start reading about compiling windows or linux modules for metamod.
I search alot and find everything, try yourself.
