I need to change css server name in another in setting i put this -hostname MyServer but its not help how to rechange this server name Counter Strike:Source in MyServer

Hey there.

You can change server name by typing hostname my_css_server in console.

However that won't last after server restart.

To make it permanent create server.cfg file in /cstrike/cfg and paste following content inside

hostname "my_css_server"

Add +exec server.cfg to the startup command in server settings. Save settings. Restart server. Enjoy.
