I want to monitor my new tor relay (set up on a raspbian pi 3 by migrating my former relay incl. keys) with nyx. When try to start nyx by "nyx" in the command line "Tor controller password" is prompted.

I can't find a password except the hashpassword in the torrc-file but that doesn't work.

I tried to set a password by "tor --hash-password <password>" but it didn't work as well.

When I start nyx with sudo it works and I can see that tor is doing well.

You need to add the user you run nyx as to the debian-tor group. The instructions are here: https://trac.torproject.org/projects/tor/ticket/25890#comment:1 They should be in the Nyx FAQ or relay guide soon. I have cc'd the people who are making that change. T

Thanks for reply! Cookieauthentication is set on 1. I did "sudo adduser $USER debian-tor". (https://trac.torproject.org/ projects/tor/ticket/25890#comment:1) On Raspbian Pi the default user is pi, so I added it as user, but it didn't help. SMichel

Try: sudo -u debian-tor nyx Thanks

sudo -u debian-tor nyx

That's it! Thanks a lot!

That's not great for security, now nyx can read your tor private keys. (It probably won't, but still…) If you add your controller to the debian-tor group, and set the appropriate options to make your cookie file group-readable, then nyx can only read those files. I'm not sure why that isn't working for you. Does your torrc-defaults or torrc contain: CookieAuthFileGroupReadable 1 If using a control socket: ControlPort unix:/path/to/file GroupWritable ControlPortFileGroupReadable 1 And maybe: DataDirectoryGroupReadable 1 T
