I am running tor on a new Ubuntu 14.04.3 LTS system. I have restarted tor a couple of times with
service tor restart
I noticed when I start arm that it is telling me that
The torrc differs from what tor's using. You can issue sighup to reload ...
It seems that tor is running with default values and is not reading /etc/tor/torrc as there is no ... -f /etc/tor/torrc option being used by the running tor when it is displayed with 'ps'.
The 'ps' output for the tor instance is
/usr/bin/tor --defaults-torrc /usr/share/tor/tor-service-defaults-torrc --hush
I had asumed that because I have set DirPort to 80 and ORPort to 443 in /etc/tor/torrc and can see in the tor log files that those two ports are reachable from outside, that the running tor was reading /etc/tot/torrc.
Something is amiss with my tor configuration but I don't know what.
Any hints as to where to look would be welcome while I try to RTFM again!
Cheers
