Server hardening

FiveM settings that close doors cheats use, and which Hydra warns about.

Hydra warns at start if these are not set. It never changes them for you.

cfg
set sv_enableNetworkedSounds false
set sv_enableNetworkedPhoneExplosions false
set sv_filterRequestControl 4
SettingWhy
sv_enableNetworkedSounds falseStops players playing sounds on everyone's game.
sv_enableNetworkedPhoneExplosions falseStops a classic way to blow up other players' cars.
sv_filterRequestControl 4Stops players taking control of entities they do not own.

Test on a copy of your server first. A few older scripts rely on networked sounds or on taking control of other players' entities.

OneSync

Hydra needs OneSync, and most of its server checks rely on it. Keep it on.
