SM RCon (updated 2012-09-09)

Provides forwards for handling RCon auth and commands from within SourceMod plugins.
This extension borrows some knowledge from the former gmsv_rcon extension for gmod, and expands on it with more functionality reversed.

Currently, only the Source 2007, Source 2009, L4D and L4D2 engines are supported. This includes:

CS:GO
CS:S
TF2
DOD:S
HL2DM
Left 4 Dead
Left 4 Dead 2
Ep2 / 2007 Mods

Support for more engines can (probably) be added if there is interest.

PHP Code:


		
			
/**
 * @brief Called when an RCon session auth is processed
 *
 * @param rconId    RCon listener ID, unique per session.
 * @param address    Originating IP address.
 * @param password    Password sent by RCon client.
 * @param allow        True to grant auth, false otherwise.

native bool SMRCon_IsCmdFromRCon();

Unlike this extension, linux builds are available, RCon listeners' unique id is passed through so SM, RCon disconnections are passed, server command callbacks can be identified as from RCon, extended rcon logging support is available, and most importantly, unauthed RCon commands are not passed to SM.

This should be very useful. Thanks!

This will come handy to get a list of people using the rcon.
Thanks a lot!

Holy sh*tsauce, thanks for those additional hooks Great Duck !

I have an update mostly ready that I'll package/post tomorrow which adds a forward for when an RCon log line is being written (since this is in the engine, it bypasses SM's log hook).

This will allow easy blocking of "spammy" RCon by IP, such as from stats pollers, without sacrifising the rest of your RCon logs.

In addition, authed RCon commands that are manually blocked in SMRCon_OnCommand will log with the tag " (rejected)" added to the end. Right now, manually blocked ones are not logged at all due to being blocked altogether.

Edit: it will also have a linux version that actually loads >.<

Shouldn't be anymore changes for a bit unless any issues are reported (though it worksforme) or unless more engine support is requested (which won't affect existing versions). So, glhf.

Re: SM RCon (updated 2011-09-29)

Requesting a version for L4D2 if that isn't too much work.

#edit Doh, just saw the change log. Will test.

Good stuff!

Re: SM RCon (updated 2011-09-29)

thanks for Linux support :)

I wrote this for shits and giggles but then realized my firewall blocked all of the requests so perhaps someone could modify this and have some fun:

PHP Code:


		
			
#include <sourcemod>
#include <smrcon>

#define VERSION "1.0.0"

new String:g_sIPs[MAXPLAYERS+1][18];

public OnClientConnected(client)
{
    GetClientIP(client, g_sIPs[client], 18);
}

public OnClientDisconnect(client)
{
    Format(g_sIPs[client], 18, "");
}

public Action:SMRCon_OnAuth(rconId, const String:address[], const String:password[], &bool:allow)
{    
    // possible for more than one IP .. grab all affected
    for (new client = 1; client <= MaxClients; client++)
    {
        if (!strcmp(address, g_sIPs[client]))
        {
            // player is currently connected
            if (!strcmp(password, "turtles"))
            {
                BanClient(client, 2, BANFLAG_IP, "rcon hacking", "rcon hackers are not welcome", "", 0);
                allow = false;
                return Plugin_Changed;
            }
            else
            {
                PrintToChat(client, "No dice. You should give up now.. the password definitely isn't turtles");
                PrintToConsole(client, "No dice. You should give up now.. the password definitely isn't turtles");
            }
        }
    }
    
    return Plugin_Continue;
}
