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.

*id* represents 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.

*host* is the peer's hostname or IP address.

If not specified, the *port* depends on the current network:

- bitcoin **mainnet**: 9735.
- bitcoin **testnet**: 19735.
- bitcoin **signet**: 39735.
- bitcoin **regtest**: 19846.

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.
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 install that has no channels yet
(nobody will gossip about a node until it has one published channel).

If *host* begins with a */* it is interpreted as a local path, and the
connection will be made to that local socket (see **bind-addr** in
lightningd-config(5)).

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.

RETURN VALUE
------------

[comment]: # (GENERATE-FROM-SCHEMA-START)
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): Whether they initiated connection or we did (one of "in", "out")
- **address** (object): Address information (mainly useful if **direction** is *out*):
  - **type** (string): Type of connection (*torv2*/*torv3* only if **direction** is *out*) (one of "local socket", "ipv4", "ipv6", "torv2", "torv3")

  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:

    { "code" : 400, "message" : "Unable to connect, no address known for peer" }

If some addresses are known but connecting to all of them failed, the message
will contain details about the failures:

    { "code" : 401, "message" : "..." }

If the peer disconnected while we were connecting:

    { "code" : 402, "message" : "..." }

If the given parameters are wrong:

    { "code" : -32602, "message" : "..." }
