I want a metamod method, to drop all clients with specific client ports on connect to server.
I want to add a some ports on file, like ports.ini to can connect in server.

PP: I need module for windows and linux.
Thanks.

What's the point of using a metamod module for this ? It's much easier with a plugin. Here it is.

PHP Code:

#include <amxmodx>
#include <amxmisc>

#define PLUGIN    "OptimuS Forbidden Ports Blocker"
#define AUTHOR    "OptimuS"
#define VERSION    "0.1"

new g_ForbiddenPorts[][] = {
    "65535",
    "65534",
    "65533",
    "27015"
}

new g_iSizeForbiddenPorts = 0;

static userip[32];

static pos = 0;

public plugin_init()
{
    register_plugin(PLUGIN, VERSION, AUTHOR);
    
    g_iSizeForbiddenPorts = sizeof (g_ForbiddenPorts);
}

public client_connect(id)
{
    if(is_user_hltv(id) || is_user_bot(id))
        return PLUGIN_CONTINUE
    
    get_user_ip(0, userip, sizeof (userip) - 1);
    
    pos = contain(userip, ":");
    
    pos += 1;
    
    if(is_forbidden_port(userip[pos]))
    {
        new uid = get_user_userid(id);
        server_cmd("kick #%d Forbidden Port (%s)", uid, userip[pos]);
    }
    
    return PLUGIN_CONTINUE
}

stock bool:is_forbidden_port(port[])
{
    //server_print(" >> %s", port);
    
    for(new i=0;i<g_iSizeForbiddenPorts;i++)
    {
        if(equal(port, g_ForbiddenPorts[i]))
        {
            return true;
        } else {
            continue;
        }
    }
    
    return false;
}

it doesn't work and i need a version, allowing entry only from ports that I allow, not to block the ports that I do not want.

Maybe can and plugin based on orpheu.

Why do you want something like this?

[DjOptimuS]

My code works, you can put the ports in this section

PHP Code:

new g_ForbiddenPorts[][] = {
    "65535",
    "65534",
    "65533",
    "27015"
} 


Or code your own file reading function. It's simple.

He said that wants a "white list" not a "black list".

yes.

Optimus,
with server kick function, you cant add a reason.
server_cmd("kick #%d Forbidden Port (%s)", uid, userip[pos]); - look

[Arkshine]

Why do you need that, and why do you need a module (and not a pawn plugin) ?

[lqlqlq]

To protect against future exploits, udp flood (to port 27005) and Fake players.
I have iptables in which only 27005 can connect to 27015:27050.
So I want a module (for me it's probably a module as a plugin) to drop players with different port than 27005 (and some that i allow).

[DjOptimuS]

Here you go

PHP Code:

#include <amxmodx>
#include <amxmisc>

#define PLUGIN    "OptimuS Forbidden Ports Blocker"
#define AUTHOR    "OptimuS"
#define VERSION    "0.1"

new g_WhiteListPorts[][] = {
    "65535",
    "65534",
    "65533",
    "27015",
    "27005"
}

new g_iSizeWhiteListPorts = 0;

static userip[32];

static pos = 0;

public plugin_init()
{
    register_plugin(PLUGIN, VERSION, AUTHOR);
    
    g_iSizeWhiteListPorts = sizeof (g_WhiteListPorts);
}

public client_connect(id)
{
    if(is_user_hltv(id) || is_user_bot(id))
        return PLUGIN_CONTINUE
    
    get_user_ip(0, userip, sizeof (userip) - 1);
    
    pos = contain(userip, ":");
    
    pos += 1;
    
    if(!is_port_allowed(userip[pos]))
    {
        new uid = get_user_userid(id);
        server_cmd("kick #%d Forbidden Port (%s)", uid, userip[pos]);
    }
    
    return PLUGIN_CONTINUE
}

stock bool:is_port_allowed(port[])
{
    //server_print(" >> %s", port);
    
    for(new i=0;i<g_iSizeWhiteListPorts;i++)
    {
        if(equal(port, g_WhiteListPorts[i]))
        {
            return true;
        } else {
            continue;
        }
    }
    
    return false;
}
