C-LIGHTNING connected from inside your firewall in 60 lines

C-lightning is pretty rich in terms of options on how to be visible and/or how to reach other nodes in the lightning network.

The purpose of this article is to put you in the condition to be reached on the Tor network in the most straightforward way I am aware of, leaving more complex and reach configurations to deeper studies. You can find the documentation [here][tordoc].

Setting up an Electrum server reachable only by you on Tor.

This small guide weill help you to set up your own Electrum Server and to make it available on Tor network so that only your client is able to reach it. The necessary steps are:

Set up Tor on your server (it can be your desktop provided that it has the necessary requirements)
Install and have your bitcoin node synchronized
Install Electrs and let it sync with your Bircoin Core node.
Set up an Hidden Service to make the Elelectrum Server Service reachable from outside in an authenticated way
Configure your client to access the authenticated service

Simple commands to extract informations from c-lightning

To see the list of lightning transactions you have to aggregate the result of two commands:

export invoices=$(lightning-cli listinvoices|jq '[.invoices[]|select( .status == "paid" )|{"payment_hash":.payment_hash, "time":.paid_at|gmtime|todate, "amount":.msatoshi,"fees":0, "description":.description}]')
export sendpays=$(lightning-cli listsendpays|jq '[.payments[]|select(.status == "complete")|{"payment_hash":.payment_hash,"time":.created_at|gmtime|todate,"amount":(.msatoshi_sent * -1),"fees":(.msatoshi_sent - .msatoshi), "description":"payment"}]')

and then you can join the two results and sort them by "time":

jq --argjson invoices "$invoices" --argjson sendpays "$sendpays" -n '$invoices + $sendpays | sort_by(.time)'

	the output of the `ots info` command is in the form:

	````
	$ ots info ../../Downloads/email.html.ots
	File sha256 hash: b5054af8078852d17d1653897a99cfd3cf7a0f0d5d33bcd15961ec619c3cb19e

	##
	## This script will extract the first 5 normal addresses and the first 5 change addresses
	## from a ledger nano S (not tested but should work with any supported hardware wallets)
	## To have more addresses it is sufficient to change the
	## `ku -j -s0/0-5`part as desired. So if someone wants 100 addresses after the 20th,
	## that part will be `ku -j -s0/20-119`.
	## Use at your own risk and check few addresses with other applications.
