Anyone managed to redirect linux server output?

[Skum]

Hi guys,

I'm having exactly the same problem as this guy.

My question is, has anyone actually managed to get the dom2 server under linux to pipe its output to a file?

Thanks,
JM

Well, yes. My server rather relies on this. Let me have a look

I can't make redirection work, either... strange but true. My server uses a virtual terminal to capture it's output, so that is probably why it works

Hmm.

The reason I ask is because I'd like to get the output of the server into a file, as I've been toying with the idea of an IRC bot that allows me to check status of the server (it already reports a new turn), something that shows me which players have already played their turn, and so on.

I reckon it's a bug!

Ahh well I worked round it by using screen and logging the output with ^a-H Weird!

Here's the code I'm currently using for running and logging my games. Maybe you can salvage the redirection code... It's a modified Version of Mose's domwatcher script. It creates a log file and a special status file that I use for creating a game status page.

PS: Mose, I hope you don't mind me posting this...

And this is the script that generates the status page out of the statsfile. You can see it in action on http://cradleofdoom.dyndns.org/gamestatus/

code:

<?php 

  $gameName     = "CradleOfDoom";  

	$stats        = file($gameName . ".stats");

	$modified     = stat($gameName . ".stats");

  $modifiedDate = date("l dS of F Y h:i:s A",$modified[9]);

	

	$pid          = $stats[0];

	$isServerOnline = exec("ps aux | awk '{print $2}' | grep -c $pid");

?>
