Automatic gameserver reboot

[msknight]

This is part of the dropcalc, but I thought that it needed its own thread because of possible issues ... it could cause some discussion.

For those that are running the V4 dropcalc already, you will know the $gameserver variables.

This has currently been tested on Linux, but I'm not sure if it will work in Windows yet. In theory, comment out the linux variables and uncomment the windows variables at the top of the php script and you are away.

On every run, it will check the gameservers listed, use the port numbers to try and determine whether the gameserver is up or down, and try to restart it if it is down.

The initial script is set to safe mode, so it will simply tell you what it would try and do ... until you chance the safe mode variable from 1 to 0. Linux users would need to run it regularly onder the crontab of the user they would normally start the gameserver under.

If you want to include the logon server in this, you can ... better to make it the first entry in the gameserver array.

Code: Select all
