[tor-relays] Relay ssh control/monitor ? Config is secure ?

Hi all, Some noob questions about controlling/monitoring my Tor relay on a Linux box... hosted in an ISP datacenter, so WAN IP and ports are showed to the www. I got SSH access. I've found tor-arm console UI, useful to show real-time bandwidth used, and other stuff. 1. If possible, I need to know if my current config is secure and useful, torrc contains ControlPort 9051 HashedControlPassword xxxxxxxxxxx CookieAuthentication 0 2. On some websites, I see screenshots with something like this on control config : /var/run/tor/control May be it's more secure on an online server ? No need to have another listening port like 9051 Sry I haven't found any information about this config... and how to make it possible... Thx for your help !
