My tor server stopped working vecause v2 has been deprecated. I could not get it into creating new v3 .onion address, so I uninstalled tor and installed again. Here is part of my torrc file:

HiddenServiceDir /var/lib/tor/hidden_service/
HiddenServicePort 22 127.0.0.1:22

I would expect that when I start tor service (by service tor start), it will generate new .onion address in file /var/lib/tor/hidden_service/host, but it does not.

In the log, there is entry

Dec 12 23:26:42 acc-box2 systemd[1]: Starting Anonymizing overlay network for TCP (multi-instance-master)...
Dec 12 23:26:42 acc-box2 systemd[1]: Started Anonymizing overlay network for TCP (multi-instance-master).

but nothing about connecting to circuits. What can be wrong please?

  • You need to delete the old onion service in /var/lib/tor/hidden_service/ before tor will create a new one.

To enforce Tor to re-create the keys you need to make the target directory empty, that's how it works

  • Yes the target directory is empty. Still..

  • can you run tor in verbose mode? Looks like an answer will be in a verbose logs.

  • When I run tor as service it creates entry in syslog that tor is running on TCP service, but it looks like tor is not running as hidden service - it does not create any file in hidden_directory. When I try to run tor as command, I get error tor: error while loading shared libraries: libevent-2.1.so.6: cannot open shared object file: No such file or directory. I am aware that installing libevent is not easy. Morevover, my system says that most recent version of libevent-2.1 is installed and I also found somewhere that recent version of tor does not need libevent library.

  • that can be a key: populate LD_LIBRARY_PATH with all the required libraries' locations. the list is given with ldd /full/path/to/executable command

  • Sorry I get ldd: No such file or directory, also I am not linux expert, so I do not know how to "populate LD_LIBRARY_PATH with all the required libraries' locations"

I had to solve things in the strange way. It looks like when I uninstalled tor v2 the libevent-2.1.so.6 got wiped out. Probably by my other actions. When I reinstalled tor and I was trying to reinstall libevent, other versions were installed, like libevent-2.2.so.1, but tor was still complaining about missing libevent-2.1.so.6. Fortunately I found it in old backup and I just copied it to /usr/lib/x86_64-linux-gnu/. The tor from the command line started to work, but it did not work as a service. I think I fixed that by changing owner of hidden_service directory to debian-tor. Then service started to work after I restarted computer. Hope this will help someone, it took me four evenings to fix.
