Configure an onion service

Install Tor

Install Tor on both client and server:

sudo apt-get install tor -y

In the server let’s edit tor’s config file /etc/tor/torrc:
```
 sudo nano /etc/tor/torrc
```
At the bottom of that file, add this:
```
 HiddenServiceDir /var/lib/tor/ssh/
 HiddenServicePort 22
```
Optional extra configurations (trade-off anonimity for better performance)
```
 SocksPort 0
 HiddenServiceNonAnonymousMode 1
 HiddenServiceSingleHopMode 1
```
Ctrl+x to save and close file.
Restart Tor:
```
 sudo systemctl restart tor
```

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

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

For example:

torify ssh jack@riludi2kstjwmlzn.onion

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
