1. Make sure there's -usercon in startup. In default server startup line looks like
./srcds_run -game csgo -console -port {{SERVER_PORT}} +ip 0.0.0.0 +map {{SRCDS_MAP}} -strictportbind -norestart +sv_setsteamaccount {{STEAM_ACC}}
change to
./srcds_run -game csgo -console -usercon -port {{SERVER_PORT}} +ip 0.0.0.0 +map {{SRCDS_MAP}} -strictportbind -norestart +sv_setsteamaccount {{STEAM_ACC}}
2. create /csgo/cfg/server.cfg file with following content
rcon_password "15aa7022f65be999d404432c76b3fa67" hostname "My new server"
3. Restart server
To connect inside csgo game console type (replace IP:PORT from control panel)
rcon_address IP:PORT
rcon_password 15aa7022f65be999d404432c76b3fa67
verify connection with
rcon status
It should output:
] rcon status hostname: My new server version : 1.38.4.6/13846 1529/8749 secure [G:1:3827339] udp/ip : 0.0.0.0:9274 (public ip: xx.xx.xx.xx) os : Linux type : community dedicated map : de_dust2 players : 0 humans, 0 bots (20/0 max) (hibernating)
