I just installed Tor on my server and am still using default torrc. It's Ubuntu 20.04.

systemctl reports it's active, but ps doesn't list it. /var/log/tor is empty, its permissions is

drwxr-s--- 2 debian-tor adm 4096 dez 31 16:18 ./

/etc/tor is

ll /etc/tor
total 32
drwxr-xr-x   2 root root  4096 dez 31 16:34 ./
drwxr-xr-x 147 root root 12288 dez 31 16:34 ../
-rw-r--r--   1 root root  8888 dez 31 16:34 torrc
-rw-r--r--   1 root root  2087 dez 31 16:34 torsocks.conf

Verifying /var/log/syslog it seems it's unable to read /etc/tor/torrc:

What might be wrong?

  • You can check the status with systemctl status tor@default and the log with journalctl -u tor@default. Are you sure the torrc has the default settings? The line Can't set a DirPort on a bridge relay; disabling DirPort suggests that something has been changed.

  • tnx! I'm setting up a new Ubuntu server and using Macrium to make backups of its partition. I had installed Tor before and had issues, so I restored the backup from before I had installed it and did it again with default settings. I can assure I had just installed it following support.torproject.org/apt/tor-deb-repo and community.torproject.org/relay/setup/bridge/debian-ubuntu and had made no changes on /etc/tor, specially on its permissions (because of this odd permissions denied error). I verified once more and whole torrc is fully commented.

  • What's the difference of service [email protected] and tor.service?

  • This is odd... [email protected] was running, IDK if that's why tor.service was failing. I tried stopping and starting both and they generate different logs on journalctl, none of them on /var/log/tor. tor@default is more detailed.

  • Somehow I got confused on tor.service and [email protected]. /var/log/tor is empty but journalctl -u tor@default shows the proper log, I applied my custom torrc and it's working.
