Server hosting configuration questions

Hi community !

Our clan has recently bought INS Sandstorm and we have hosted our own server.

We are trying to configure our server and we are missing with some points that we need help.
We cannot activate rank mod for players and we are all stuck at level 1. How can we activate this feature ?
Also, how can we activate ressuply points after each rounds ?

We have seen other servers with this configuration activated and we would like to do so too.

Our server is a dedicated server running on a Debian 9.4 64x with Intel i7-6700K (4c/8th) 64GB DDR4 2400MHz 480 GB SSD

I hope you guys can help us, see you in the game !

Regards

why hosting this from a pc?
