Linux server configs

[KNOWFEAR]

My Friend has set up a small private server for us and a few friends, but he is busy with trying to fix up one of his cars and would like to give him a hand with the server configs, the problem is I don't know much about linux or server configs :/

was just wondering if anyone could help me out if they already have configs or know where i can look for them ?

the things we would like to do is enable all of the modes on rai's minimap, and NEI.

also disable or just nerf the shit out of creepers

thanks
