Verbose/Debug output?

Hello!

I'm using your great program one a machine and it is working well.

However, on another machine, it seems I can only get dms to serve files from my main user. Once I shut it down and try launching from a different (less privileged) user, it doesn't seem to work.

Is there a debug mode, or verbose mode, or logging setup I can activate? When running on the other user, I just get normal startup messages (e.g., *[main dms server github.com/anacrolix/dms/dlna/dms.(*Server).Init:918]: HTTP srv on [::]:1338*) followed by idle nothingness. I can't tell if my issue relates to permissions, system groups, firewall, etc.
