Configure Tor

Install Tor

Tor is a public relay network that helps us to both anonymize our node’s location, as well as be able to accept incoming connections through a “Tor Hidden Service.” Even if our node is running on clearnet, installing Tor is often useful, as it allows to reach Tor-only nodes and make ourselves available through a hidden service, which can make connections to Tor nodes more reliable.

Useful resources:

Install Tor from the repository

You can install tor from the Ubuntu software repository with the command:

sudo apt install tor

Congratulations, you have installed Tor! Skip ahead to see how to configure Tor and LND

Install Tor from source

You may install Tor from source using the instructions below.

Prepare our machine

We will have to install some packages on our machine so we can compile Tor.

sudo apt install libssl-dev zlib1g zlib1g-dev asciidoc

Download and compile Tor

We will once again compile Tor from source. We will enter our git directory and clone the source code from there.

cd ~/git
git clone https://git.torproject.org/tor.git
cd tor

We will compile the code by executing the commands below, one by one. Look out for eventual error messages!

make install

Congratulations, you have installed Tor! Continue below to configure Tor and LND](#configure-lnd)

Configure Tor

To make use of Tor with LND, we best give LND access to the Tor daemon and handle all the details itself. For that we will need to generate another password. Use your password manager and retain it until you are done this guide. You won’t have to record this password or retain it after this configuration.

tor --hash-password dontusethisyouwillbehacked

Using your own password above, you should get an output like this:


Now we will edit the tor configuration file. You can find it like this:

sudo nano /etc/tor/torrc

Find the section that starts with #HashedControlPassword and enter in a new line below. Don’t forget to replace the hash with your personal hash as obtained above!

HashedControlPassword 16:1394205CE9C9256460207A14A8C90FF867FA3B5C6EC2A2054615D71871

Additionally, we will have to find the line that reads #ControlPort 9051 and remove the pound sign so it reads:

ControlPort 9051

We now save and close the editor and restart Tor with the command:

sudo service tor restart

Configure LND

We will mainly have to again amend settings. This will set LND to listen to incoming connections, activate tor and tell it how to connect and authenticate to Tor.

nano ~/.lit/lit.conf

We will enter the following lines:

# Tor configuration

Optionally, we may also add the following line. Only add this line if you are also operating on clearnet, or if you are comfortable revealing your home IP address to your clearnet peers.


We will save and exist the editor.

Test LND

We can test our installation and connection with the command:


If it doesn’t stop or crash with an error, great! We’ve completed our Tor configuration process!

You can stop the process by pressing Ctrl + C. That should send the shutdown signal and litd should shut down gracefully.

Configure Bitcoin Core (optional)

We can also configure Bitcoin Core to connect to its peers over the Tor network.

All we’ll have to do is add the following line to our configuration file in ~/.bitcoin/bitcoin.conf.
