First you need to transfer some funds to lightningd so that it can open a channel:
# Returns an address <address>
lightning-cli newaddr
lightningd will register the funds once the transaction is confirmed.
You may need to generate a p2sh-segwit address if the faucet does not support bech32:
# Return a p2sh-segwit address
lightning-cli newaddr p2sh-segwit
Confirm lightningd got funds by:
# Returns an array of on-chain funds.
lightning-cli listfunds
Once lightningd has funds, we can connect to a node and open a channel. Let's assume the remote node is accepting connections at <ip> (and optional <port>, if not 9735) and has the node ID <node_id>:
lightning-cli connect <node_id> <ip> [<port>]
lightning-cli fundchannel <node_id> <amount_in_satoshis>
This opens a connection and, on top of that connection, then opens a channel.
The funding transaction needs 3 confirmations in order for the channel to be usable, and 6 to be announced for others to use.
You can check the status of the channel using lightning-cli listpeers, which after 3 confirmations (1 on testnet) should say that state is CHANNELD_NORMAL; after 6 confirmations you can use lightning-cli listchannels to verify that the public field is now true.
