I am running a full node on a static IP and I can open up whatever ports needed to communicate with that node.
I need to figure out how to communicate with that full node remotely. I want to run an implementation of lightning but don't know what is best to use, LND, C-lightning, Eclair, etc.
I will be traveling and will have my lightning on a USB stick and then want to communicate with my remote full node.
Is this even possible ?
With C-lightning you can connect your lightning node to a remote full node:
~/.lightning/config
bitcoin-rpcconnect=<remote-ip>
bitcoin-rpcport=<rpc-port>
bitcoin-rpcuser=<rpc-user>
bitcoin-rpcpassword=<rpc-password>
alias=<alias>
network=bitcoin
Then start the lightning application:
$ lightningd --daemon
Note this will require enabling the RPC server (server=1 in bitcoin.conf) on the full node and configuring the authentication. See
$ bitcoind --help
...
-rpcauth=<userpw>
Username and hashed password for JSON-RPC connections. The field
<userpw> comes in the format: <USERNAME>:<SALT>$<HASH>. A
canonical python script is included in share/rpcuser. The client
then connects normally using the
rpcuser=<USERNAME>/rpcpassword=<PASSWORD> pair of arguments. This
option can be specified multiple times
