[CoD2][Tutorial] How to make your cracked server show up in the master list

[Mitch]

I will use linux now, windows suck and it make some lags at the game servers.

So if i need to make a cracked server i must add the following commands ?

It is not required. You can also use the lines in my first post without any trouble.

But if you want to be sure that it only drops the traffic that comes from the master server you can use the -s param. It is unlikely that there will come much traffic to your game server ports from the port 20700. And even then it will only drop the packets when they contain "BANNED_CDKEY" or "INVALID_CDKEY".
The only difference is probably with -s param that it will use less CPU, because it will only read the data from the packets from that ip.
