nyx with tor service about nyx HOT 6 CLOSED

Ok, I'm not sure I quite understand.

But I got it working,

1. for file /etc/tor/torrc, I added:

ControlPort 9051
CookieAuthentication 1
CookieAuthFileGroupReadable 1

2. Added group tor to $USER.

3. Then chowned: chown $USER:tor /var/run/tor/control.authcookie

4. Restarted tor service: sudo systemctl restart tor

5. nyx is now run without sudo, displaying real-time information.

Hi, that is certainly odd. Unless I'm missing something this can only arise if nyx believes tor is running within a chroot. Are you running FreeBSD or does your non-root user have a '~/.nyx/config' with a 'tor_chroot' field?

https://gitweb.torproject.org/nyx.git/tree/nyx/__init__.py#n383

If not, please run 'nyx --debug' with your non-root user and provide the debug output (minus anything you feel is sensitive).

Thanks!

Hi @atagar, thanks for the reply!

ok, so in '~/.nyx/config' I had tor_chroot with value: tor_chroot /var/run/tor/control
This was the reason for Path: /var/run/tor/control/var/run/tor/control.authcookie
Then I commented that line out, nyx -debug, this returned

Saving a debug log to ebug, please check it for sensitive information before sharing it.
We were unable to read tor's authentication cookie...

  Path: /var/run/tor/control.authcookie
  Issue: Authentication failed: unable to read '/var/run/tor/control.authcookie' ([Errno 13] Permission denied: '/var/run/tor/control.authcookie')

Does this mean it's not possible to use nyx as non-root user on a root service?

Hi, it means that your authentication cookie isn't readable by your user. Tor obnoxiously requires some additional setup (#24). Please check your cookie's filesystem permissions, then adjust torrc options like CookieAuthFileGroupReadable so your nyx user can read it.

May I ask something although it's closed?

I'm facing the same error. Could you pls clarify what to do on step 2 Added group tor to $USER?

In my installation, there's no group or user tor. Should I create one or even both of them?
