Configure an onion service

Shamelessly copied from https://www.techrepublic.com/article/how-to-run-an-ssh-connection-through-tor/

---

Install Tor

Install Tor on both client and server:

sudo apt-get install tor -y

Configure Tor

1. In the server let's edit tor's config file /etc/tor/torrc:

    sudo nano /etc/tor/torrc
   

2. At the bottom of that file, add this:

    HiddenServiceDir /var/lib/tor/ssh/
    HiddenServicePort 22
   

   Ctrl+x to save and close file.

3. Restart Tor:

    sudo systemctl restart tor
   

Get .onion address

It will be in the file hostname in the previously configured folder /var/lib/tor/ssh

sudo cat /var/lib/tor/ssh/hostname

You should get something like riludi2kstjwmlzn.onion

Connect to the Tor hidden ssh server

torify ssh ... # replace the domain/ip with the .onion address

For example:

torify ssh jack@riludi2kstjwmlzn.onion

Optional

You don't need to remember the .onion address, you can write an entry to your user's ssh config file ~/.ssh/config:

nano ~/.ssh/config

Set configuration:

Host serverTor
    User jack
    HostName riludi2kstjwmlzn.onion
    Port 22

Now you can simply connect with:

torify ssh serverTor
