GoldSRC RCON Query Include [ SVN ]
Version: 0.1

You can send RCON commands for HLDS server from your AMXX plugin.
Im used "Thread Socket" method in this include, so it doesn't not interrupt gameplay while querying.

Functions:

rcon_send( ip[] , port , szPass[] , szCommand[] , szForward[] , Float:timeout = 5.0 ) - send RCON command to server.

• ip[] - remote server IP address.
• port - remove server port.
• szPass[] - RCON password.
• szCommand[] - RCON command.
• szForward[] - forward function for receive result from server.
  • Forward( iRconStatus , szResult[] )
    • iRconStatus - RCON status.
    • szResult - RCON command result.
• Float:timeout - timeout time.
• @return - RCON_OK if OK or error code.

Error codes

• RCON_CONNECTION_FAILED - connection to server failed.
• RCON_GET_CHALLENGE_FAILED - failed to get rcon challenge number (successfully connetec, нbut something is goes wrong).
• RCON_CREATE_FWD_FAIL - failed to create forward.
• RCON_TIMEOUT - query timeout.
• RCON_OK - there there should be error, but there is no.

Example usage:

#include <amxmodx>
#include <rcon>

#define SRV_IP      "localhost"
#define SRV_PORT   27015
#define SRV_PASS   "1337"

public plugin_init() {
   register_plugin("RCON Test","test","serfreeman1337")
   
   register_clcmd("amx_rcon_send","Try_Rcon_Send")
}

public Try_Rcon_Send(){
   new cmd[128]
   read_args(cmd,127)
   trim(cmd)
   remove_quotes(cmd)
   
   new st = rcon_send(SRV_IP,SRV_PORT,SRV_PASS,cmd,"rcon_handler")
   
   switch(st){
      case RCON_CONNECTION_FAILED: server_print("[ RCON ] Connection to %s:%d failed successfully",
         SRV_IP,SRV_PORT)
      case RCON_CREATE_FWD_FAIL: server_print("[ RCON ] Forward create failed")
   }
}


public rcon_handler(status,result[]){
   switch(status){
      case RCON_GET_CHALLENGE_FAILED:
         server_print("[ RCON ] Get RCON challenge failed",status)
      case RCON_TIMEOUT:
         server_print("[ RCON ] Query timeout on %s",result)
      case RCON_OK:
         server_print("[ RCON ] Response: ^n%s",result)
   }
}

Notes

• There is problem with large result, which take more than one packet from server.
• If you execute many rcon_send at same time im same plugin something goes wrong.

Very cool, this can be very useful with servers comunication plugins. Will using, thank you . But here is a one question, is possible to get returned values by RCON?

[Kia]

public rcon_handler(status,result[]){

[Backstabnoob]

Good job.

[kiki33hun]

Not bad idea

[WiggPerson]

Not possible to get returned value of RCON:

PHP Code:

public plugin_init() {
     register_concmd("return100","return100function",ADMIN_RCON);
}

public return100function() {
     return 100; // Get this in szResult[] in plugin on second server
} 


PHP Code:

public plugin_init() {
     rcon_send("255.255.255.255",25555,"return100","password","rconforward")
}

public rconforward(iStatus,szResult[]) {
     print_console("%s",szResult) // This is not 100
} 


[Kia]

Shouldn't it be a integer (%i) since you're returning a number?

The result is returned in string as 2nd parameter. (No 100 but "100")

[Kia]

PHP Code:

public return100function() {
     return 100; // Get this in szResult[] in plugin on second server
} 


You return a Integer, not a string.

Your Code should be

PHP Code:

public rconforward(iStatus, iResult) {
     print_console("%i", iResult)
} 


[WiggPerson]

It think it does not matter 'cause rcon access return in string, please @GordonFreeman (RU) tell us, how it exactly works.
