This is the first time I'm running a relay. Doing it on a raspbian, and I've got some short questions. Be ready: I'm a newb.

I'm only controlling my raspberry via SSH, so no GUIs.

I opened ports on my firewall. /var/log/tor/log tells me there is a successfull circuit, bootstrapped 100%. Good, right? Then there is something that confuses me: [notice] Interrupt: exiting cleanly. I was not expecting this. Does anyone know what it means? Moreover, arm gives only positive output on connectivity related things.

Everytime I open arm it tells me my relay is unresponsive. About 15 seconds later it notices that the relay is resumed. I do see some activity on the traffic graphs. Why is this? Is my relay stopped as soon as i close arm? (I presume not, the tor service and process are still running after). Is there a way to verify traffic is coming in and out, without using arm? arm doesn't show an uptime in it's interface, where it should. Is this related?

Traffic has stopped almost completely after +/- 2 days. This is not what I was expecting after reading the post on torproject blog about traffic amounts from new relays.

What is the use for tor and arm to run as a unique user? Security related reasons? Standard linux stuff?

Extra info: The relay has flags RUnning, V2Dir, Valid

I hope someone takes the time to answer these questions. Thanks in advance!
