server.cfg is the SA-MP server’s configuration file. Each line is a setting name, a space and a value, for example hostname My Server. On a FREAKHOSTING SA-MP server it is in the main folder: edit it in Files, save and restart. The panel sets port, maxplayers and rcon_password at every start; you change all other lines yourself.

​
What is in server.cfg on a new server?

Lower onfoot_rate, incar_rate and weapon_rate values improve sync but use more bandwidth.

​
Which settings can I add?

Don’t add weather or gravity to server.cfg. The official documentation warns that both crash the server on startup. Set them in your script (SetWeather, SetGravity) or with RCON.

​
How to edit server.cfg

1

Open the file

In the Game Panel, open your server, click Files and open server.cfg.
2

Change or add lines

Edit a value or add a new line. Keep one setting per line and one line per setting.
3

Save and restart

Save the file and restart the server. If something breaks, use the editor’s History button to go back to an earlier version.

​
Frequently asked questions

​
How do I change my SA-MP server name?

Change the hostname line, save and restart. As an RCON admin you can also use /rcon hostname <name>; that lasts until the next restart.

​
Why does my maxplayers value change back?

The panel writes Max Players from Startup into maxplayers at every start. Your slots are set by your plan; for more, open a ticket.

​
Why does my rcon_password change back?

The panel writes the Rcon password from Startup at every start. Change it there instead.

​
Can I change settings without a restart?

Many settings can be changed for the running server with RCON, for example /rcon hostname or /rcon password. These changes are lost at the next restart. See RCON commands.
