yeah, simple example, hope ppl can use this as frame:
(there was a bug in php that did prevent reading from udp stream, tho it was fixed in 4.3.1 (or smthng), so you'll need recent version of php for this.
Code: Select all
<?php
//set servers rcon password
$rcon_password = "SecreT"
//command to send to server
$yourcommand = "say message from outer world: it's SUMMER!";
//open connection
$conn = fsockopen( "udp://10.0.0.1", 27910, $error, $errdescription, 10 );
//check if connection was made
if ($conn) {
//send data to server
fputs( $conn, "\xff\xff\xff\xff".$yourcommand);
//parse output
$output = str_replace("ÿ", "", (fread( $conn, 1024 )));
//aaand make array out of it
$reply = split ("\x0a", $output);
//then let's see what we wanna do with those rows that server sent back
foreach ($reply as $r) {
//as i am simple man, i don't wanna do anything but print the output
print $r."\n";
}
}
//something ain't working
else {
//i've seen it all
die("ERROR with connection: ".$errdescription);
}
?>

yeah, just add fputs-lines for every rcon command you want to issue, and so on. you don't NEED to check the reply btw. if you just wanna execute rcon commands, skip the postprocessing.
and simple remote console for server would be:
Code: Select all
<html>
<body>
<?php
//set server's rcon password
$rcon_password = $_POST['rcon'];
//command to send to server
$yourcommand = $_POST['command'];
//server address
$serveraddr = $_POST['server'];
//open connection
$conn = fsockopen($serveraddr, 27910, $error, $errdescription, 10);
//check if connection was made
if ($conn) {
//send data to server
fputs( $conn, "\xff\xff\xff\xff".$yourcommand);
//parse output
$output = str_replace("ÿ", "", (fread( $conn, 1024 )));
//aaand make array out of it
$reply = split ("\x0a", $output);
//then let's see what we wanna do with those rows that server sent back
foreach ($reply as $r) {
//as i am simple man, i don't wanna do anything but print the output
print $r."<br>\n";
}
}
print "<form action=\"".$_SERVER['PHP_SELF']."\" method=\"post\">";
?>
<input type="text" name="server" size="20"> : server address<br>
<input type="text" name="rcon" size="20"> : rcon password<br>
<input type="text" name="command" size="20"> : command<br>
<input type="submit">
</form>
</body>
</html>

spectre, this looks intresting... I have used a bit these php -> q2 things, but I haven't put enough effort to resolve those things what you need to send to q2 server...
where did you hack that '\xff\xff\xff\xff'? from q2 source?

i copypasted everything from that finished script but for some reason it doesn't work, it just prints:
Warning: fsockopen(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /home/kaaos/public_html/q2server.php on line 14
Warning: fsockopen(): unable to connect to :27910 in /home/kaaos/public_html/q2server.php on line 14
and the input boxes below it.

nope, just captured the rcon packets from homenetwork, simple logic helped me a bit too ;)
kaaos:
seems like your php can't handle udp connections, what's the version and os the php runs on? shouldn't be os relevant, but anyway.
