Dunno about the linux part, but for now, you still need Steam to run the Dedicated ! So only downloading through Steamcmd is not going to work!
thanks for your response Erick, if i understand, on ly windows machine whith steam account and program installed on machine can launch AMS server
Right, that's a shame. So its still the same, that is, I cannot host a dedicated server unless I am logged in with my steam account on the windows server!!??
