I'm running Ubuntu 18.04 server, headless and installed tor using the debian instructions on the tor project. However, nyx will not run to show me tor connection information, when I enter nyx I receive the message: Unable to connect to tor. Maybe it's running without a ControlPort?

However, I can see tor running when I run top.

   921 root      20   0   75448  19400   6356 S   0.3  0.5   0:03.12 tor  

But, when I run systemctl | grep tor I see:

● tor.service            loaded active exited    Anonymizing overlay network for TCP (multi-instance-master)                  
● tor@default.service    loaded failed failed    Anonymizing overlay network for TCP                

I've configured my 'tor service' in /usr/share/tor/tor-service-defaults-torrc and that file's contents are:

DataDirectory /var/lib/tor
PidFile /run/tor/tor.pid
RunAsDaemon 1
User debian-tor

ControlSocket /run/tor/control GroupWritable RelaxDirModeCheck
ControlSocketsGroupWritable 1
SocksPort unix:/run/tor/socks WorldWritable
SocksPort 9050

ControlPort 9051
CookieAuthentication 1
CookieAuthFileGroupReadable 1
CookieAuthFile /run/tor/control.authcookie

Log notice syslog

Any help to get nyx working and improve my tor implementation is appreciated.


I found the answer in this post the issue was that another tor service was running, blocking access to the control port. The following code fixed the problem:

sudo netstat -plnt | fgrep 9050

To find the other service hogging the control port.

sudo killall tor

To kill all tor processes.

sudo systemctl start tor.service

Then I ran journalctl -xe to make sure that tor booted correctly.

sudo -u debian-tor nyx

Solution is running nyx as user tor (i.e. debian-tor in Ubuntu 18.04). In this case just these 2 lines about control port needed in torrc.

ControlPort 9051
CookieAuthentication 1
