LIGHTNING-CONNECT(7) LIGHTNING-CONNECT(7) NAME lightning-connect -- Command for connecting to another lightning node SYNOPSIS connect id [host] [port] DESCRIPTION The connect RPC command establishes a new connection with another node in the Lightning Network. Connecting to a node is just the first step in opening a channel with another node. Once the peer is connected a channel can be opened with lightning-fundchannel(7). If there are active channels with the peer, connect returns once all the subdaemons are in place to handle the channels, not just once it's connected. • id (string): The target node's public key. As a convenience, id may be of the form id@host or id@host:port. In this case, the host and port parameters must be omitted. This can fail if your C-lightning node is a fresh install that has not connected to any peers yet (your node has no gossip yet), or if the target id is a fresh in- stall that has no channels yet (nobody will gossip about a node un- til it has one published channel). • host (string, optional): The peer's hostname or IP address. If host is not specified (or doesn't work), the connection will be attempted to an IP belonging to id obtained through gossip with other already connected peers. If host begins with a / it is interpreted as a lo- cal path and the connection will be made to that local socket (see bind-addr in lightningd-config(5)). • port (u16, optional): The peer's port number. If not specified, the port depends on the current network: • bitcoin mainnet: 9735. • bitcoin testnet: 19735. • bitcoin signet: 39735. • bitcoin regtest: 19846. RETURN VALUE On success, an object is returned, containing: • id (pubkey): The peer we connected to. • features (hex): BOLT 9 features bitmap offered by peer. • direction (string) (one of "in", "out"): Whether they initiated con- nection or we did. • address (object): Address information (mainly useful if direction is out).: • type (string) (one of "local socket", "ipv4", "ipv6", "torv2", "torv3"): Type of connection (torv2/torv3 only if direction is out). If type is "local socket": - socket (string): Socket filename. If type is "ipv4", "ipv6", "torv2" or "torv3": - address (string): Address in expected format for type. - port (u16): Port number. ERRORS On failure, one of the following errors will be returned: • 400: Unable to connect, no address known for peer • 401: If some addresses are known but connecting to all of them failed, the message will contain details about the failures • 402: If the peer disconnected while we were connecting • -32602: If the given parameters are wrong AUTHOR Rusty Russell <<rusty@rustcorp.com.au>> is mainly responsible.
