I try to create a C/C++ application that handle servers logs by throwing them to my application but I am not sure how to proceed, I've read several valve wiki page about it and I'm just getting confuse about the protocol. Can anyone show me a basic example how I can done this feature?

Further explanation and example: It a bit like HLSW giving you the output of what going on in the server.

Thank you, Nighty's.

There is not much of a protocol. It sends the log data raw through udp, with each packet having a single char prefix, 'R'.

Set log_address to the ip:port for the game server to send logs to and make sure that logging is enabled ("log 1" or "log on"), and it will start streaming the log to the address, just as you would see in the log file (again, with the prefix).

Additionally, for games that support the sv_logsecret cvar, if the cvar is set, the prefix will instead be a single char, 'S', followed by the secret.

ie.:

RL 01/04/2009 - 12:48:24: server_cvar: "mp_timelimit" "20"
RL 01/04/2009 - 12:49:30: "psychonic<2><STEAM_ID_PENDING><>" connected, address "192.168.5.115:27006"
RL 01/04/2009 - 12:49:31: "psychonic<2><STEAM_0:1:4153990><>" STEAM USERID validated
RL 01/04/2009 - 12:50:02: "psychonic<2><STEAM_0:1:4153990><>" entered the game

or with an sv_logsecret of "jabroni":

SjabroniL 01/04/2009 - 12:48:24: server_cvar: "mp_timelimit" "20"
SjabroniL 01/04/2009 - 12:49:30: "psychonic<2><STEAM_ID_PENDING><>" connected, address "192.168.5.115:27006"
SjabroniL 01/04/2009 - 12:49:31: "psychonic<2><STEAM_0:1:4153990><>" STEAM USERID validated
SjabroniL 01/04/2009 - 12:50:02: "psychonic<2><STEAM_0:1:4153990><>" entered the game

that exacly what Im looking for, so how do I create a simple C application handle the logs to a file for example.
Would be really apreciate.

EDIT: I will reformulate my request. How do I create a UDP socket listener to read the logs through network, after googling for hours and read many and different method I am stuck right now, do I have to use datagram or stream method and a simple code example would be really really appreciated. window socket if possible.

Thank you, Nighty's.

Since you are trying UDP you should use SOCK_DGRAM:

what am I doing wrong?

PHP Code:

#pragma once
#pragma comment(lib, "Ws2_32.lib")

#include <WinSock2.h>
#include <Windows.h>
#include <iostream>

using namespace std;

int main()
{
        WSAData wsaData;
        WORD DllVersion = MAKEWORD(2,2);

        int startup_RetVal = WSAStartup(DllVersion, &wsaData);

        SOCKET sSocket = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);

        SOCKADDR_IN addr;

        addr.sin_addr.s_addr = inet_addr("127.0.0.1");
        addr.sin_family = AF_INET;
        addr.sin_port = htons(2222);

        bind(sSocket, (SOCKADDR*)&addr, sizeof(addr));

        char buf[64] = {0};

        recvfrom(sSocket, buf, 64, NULL, NULL, NULL);

        cout << buf << endl;

        getchar();

        return 0;
} 


the application compile and run correctly but it does not receive any logs.

my server logaddress_list:

192.95.xxx.xxx:7130 (hlsw)
192.95.xxx.xxx:2222 (my application)

HLSW receive correctly the log but my application do not receive anything.

I can't test this right now. But since you are not checking the return value of bind() you might not even get the socket created.

Here is a link to the code of a small UPD-receiver:

You're listening on 127.0.0.1 but sending logs to 192.95.xxx.xxx

Listen on the IP that you're sending logs to, or the internal IP that corresponds to it if you're behind NAT.

[Mathias.]

127.0.0.1 isnt local and should grab my public ip automaticly? I will try it later and give you news, I'm leaving for the day and may be back later.

By the way thanks alot for the help guys, it really appreciated that I've receive reply and help from the community that fast.

Networking isn't my strong suit, but my impression is that 127.0.0.1 (or localhost) will only receive traffic if you explicitly send it there. It's not the same as listening on all interfaces.

[asherkin]

0.0.0.0 is generally all interfaces, 127.0.0.1 is loopback only.
