You have a Ubuntu server already running lnd
.
Your Ubuntu server has bitcoind
installed, synced on mainnet, and running as a daemon.
To install bitcoind
on Ubuntu, follow the official bitcoin.org guide.
Your bitcoin.conf
file has ZMQ publishing turned on.
Txindex is not required, but pruned mode is not supported.
Download the version of the latest Lightning Terminal release that matches your local configuration (likely linux-amd64). Extract the compressed files, and install the binaries using the below instructions.
# If you have go installed...# Extract the compressed files, and install them in your GOPATHtar -xvf lightning-terminal-<YOUR_LOCAL_VERSION>.tar.gz --strip 1 -C $GOPATH/bin​# Linux requires this in order for LiT to listen on a port below 1024sudo setcap 'CAP_NET_BIND_SERVICE=+eip' $GOPATH/bin/litd​# If you do not have go installed...# Extract and install the compressed files, and add their location to your PATHtar -xvf lightning-terminal-darwin-amd64-<YOUR_LOCAL_VERSION>.tar.gzcd lightning-terminal-darwin-amd64-<YOUR_LOCAL_VERSION>PATH=$PATH:$PWDsudo setcap 'CAP_NET_BIND_SERVICE=+eip' ./litd
Ensure that your server has only the required ports open for outbound communication with the Lightning Network.

To connect Lightning Terminal to a remote lnd
instance first make sure your remote lnd.conf
file contains the following additional configuration settings:
tlsextraip=<YOUR_LND_IP>rpclisten=0.0.0.0:10009
Copy the following files that are located in your ~/.lnd/data/chain/bitcoin/mainnet
directory on your remote machine to /some/folder/with/lnd/data/
on your local machine (where you’ll be running LiT):
tls.cert
admin.macaroon
chainnotifier.macaroon
invoices.macaroon
readonly.macaroon
router.macaroon
signer.macaroon
walletkit.macaroon
Create a lit.conf
file.
mkdir ~/.litvi ~/.lit/lit.conf
Storing the configuration in a persistent ~/.lit/lit.conf
file means you do not need to type in the command line arguments every time you start the server. Make sure you don't add any section headers (the lines starting with [ and ending with ], for example [Application Options]) as these don't work with the additional levels of sub configurations.
Paste this example lit.conf
file into your terminal, and fill in the placeholders with your specific information.

If you are using a cloud provider, double check using their configuration tools that inbound ports 443, 9735, and 10009 are allowed. Once you've done that, and you've ensured your remote lnd
instance is running, it's time to get LiT!
litd --uipassword=<YOUR_UI_PASSWORD>
Visit https://localhost:8443 to access LiT.
Because not all functionality of lnd
(or loop
/faraday
for that matter) is available through the web UI, it will still be necessary to interact with those daemons through the command line.
We are going through an example for each of the command line tools and will explain the reasons for the extra flags. The examples assume that LiT is started with the following configuration (only relevant parts shown here):
httpslisten=0.0.0.0:443lit-dir=~/.lit​remote.lnd.network=testnetremote.lnd.rpcserver=some-other-host:10009remote.lnd.macaroondir=/some/folder/with/lnd/dataremote.lnd.tlscertpath=/some/folder/with/lnd/data/tls.cert
Because in the remote lnd
mode all other LiT components (loop
, pool
, faraday
and the UI server) listen on the same port (443
in this example) and use the same TLS certificate (~/.lit/tls.cert
in this example), some command line calls now need some extra options that weren't necessary before.
NOTE: All mentioned command line tools have the following behavior in common: You either specify the --network
flag and the --tlscertpath
and --macaroonpath
are implied by looking inside the default directories for that network. Or you specify the --tlscertpath
and --macaroonpath
flags explicitly, then you must not set the --network
flag. Otherwise, you will get an error like [lncli] could not load global options: unable to read macaroon path (check the network setting!): open /home/<user>/.lnd/data/chain/bitcoin/testnet/admin.macaroon: no such file or directory
The lncli
commands in the "remote" mode are the same as if lnd
was running standalone on a remote host. We need to specify all flags explicitly.
$ lncli --rpcserver=some-other-host:10009 \--tlscertpath=/some/folder/with/lnd/data/tls.cert \--macaroonpath=/some/folder/with/lnd/data/admin.macaroon \getinfo
This is where things get a bit tricky. Because as mentioned above, loopd
also runs on the same port as the UI server. That's why we have to both specify the host:port
as well as the TLS certificate of LiT. But loopd
verifies its own macaroon, so we have to specify that one from the .loop
directory.
$ loop --rpcserver=localhost:443 --tlscertpath=~/.lit/tls.cert \--macaroonpath=~/.loop/testnet/loop.macaroon \quote out 500000
You can easily create an alias for this by adding the following line to your ~/.bashrc
file:
alias lit-loop="loop --rpcserver=localhost:443 --tlscertpath=~/.lit/tls.cert --macaroonpath=~/.loop/testnet/loop.macaroon"
Again, poold
also runs on the same port as the UI server and we have to specify the host:port
and the TLS certificate of LiT but use the macaroon from the .pool
directory.
$ pool --rpcserver=localhost:443 --tlscertpath=~/.lit/tls.cert \--macaroonpath=~/.pool/testnet/pool.macaroon \accounts list
You can easily create an alias for this by adding the following line to your ~/.bashrc
file:
alias lit-pool="pool --rpcserver=localhost:443 --tlscertpath=~/.lit/tls.cert --macaroonpath=~/.pool/testnet/pool.macaroon"
Faraday's command line tool follows the same pattern as loop. We also have to specify the server and TLS flags for lnd
but use faraday
's macaroon:
$ frcli --rpcserver=localhost:443 --tlscertpath=~/.lit/tls.cert \--macaroonpath=~/.faraday/testnet/faraday.macaroon \audit
You can easily create an alias for this by adding the following line to your ~/.bashrc
file:
alias lit-frcli="frcli --rpcserver=localhost:443 --tlscertpath=~/.lit/tls.cert --macaroonpath=~/.faraday/testnet/faraday.macaroon"
