Im not very experienced with sockets but i need to make a listener to packets from any host ip (so recieve from any ip packets). I want to filter some commands from rcon.
so what i need basically g_myAwesomeSocket = socket_listen(any host?, 27015, SOCKET_TCP, szError)
Thank you :]

I modified the code of a plugin that does what you are asking to fit as an example.

#include <amxmodx>
#include <engine>
#include <sockets_hz>

#define IP      "127.0.0.1"
#define PORT            1337
#define THINK_DELAY  0.01
#define RECEIVE_DELAY      1.0

new g_socket;
new g_entity;

public plugin_init()
{
    register_plugin("Listening Socket Example", "-0.1", "Exolent");
    
    new error;
    g_socket = socket_listen(IP, PORT, SOCKET_TCP, error);
    
    if( error )
    {
        switch( error )
        {
            case 1:    log_amx("Error creating a TCP socket to %s:%i", IP, PORT);
            case 2:    log_amx("Error resolving the hostname for %s:%i", IP, PORT);
            case 3:    log_amx("Error connecting a TCP socket to %s:%i", IP, PORT);
        }
        
        return;
    }
    
    socket_unblock(g_socket);
    
    g_entity = create_entity("info_target");
    
    if( is_valid_ent(g_entity) )
    {
        entity_set_string(g_entity, EV_SZ_classname, "TCP_Socket_Reader");
        entity_set_float(g_entity, EV_FL_nextthink, get_gametime() + THINK_DELAY);
        
        register_think("TCP_Socket_Reader", "FwdThink");
    }
    else
    {
        log_amx("Could not create TCP Socket Receiver entity.");
        
        plugin_end();
    }
}

public plugin_end()
{
    if( g_socket > 0 )
    {
        socket_close(g_socket);
    }
}

public FwdThink(entity)
{
    if( entity != g_entity ) return;
    
    static socket;
    
    if( (socket = socket_accept(g_socket)) > 0 )
    {
        socket_unblock(socket);
        
        set_task(RECEIVE_DELAY, "TaskReceiveData", socket);
    }
    
    entity_set_float(entity, EV_FL_nextthink, get_gametime() + THINK_DELAY);
}

public TaskReceiveData(socket)
{
    // socket_recv(socket, ...);
}

Hope this helped.

Wow that is the best reply ever <3
and haha using the engine think would be epic too ! thanks

yeah but how to listen all ips not just loopback?

[issen1]

Maybe using "0.0.0.0" as ip works.

[ARES[ro]]

no

Don't bump so soon. And this LISTENS on a single ip (the host) and will accept any data sent to it, aslong as it's sent properly.

[ARES[ro]]

so there is no way to set up a raw socket?
also*** i know hackinzer did it in his irc plugin but i cant really understand it

[Exolent[jNr]]

Don't bump until 2 weeks have passed since last post.

That does listen for all IPs on the specified port. That code receives data, not sends.

[issen1]

The parameter IP for socket_listen specifies the network interface to listen on. So you either pass the public ip address of your server with this param or try 0.0.0.0 which means that the socket will listen on ALL network interfaces. If you specify localhost, the server will only accept connections coming from the host system.

So IP doesn't mean which remote IPs are allowed to connect, but on which network interface the server is listening.
