lightning-commando -- Command to Send a Command to a Remote Peer

SYNOPSIS

commando peer_id method [params] [rune] [filter]

DESCRIPTION

The commando RPC command is a homage to bad 80s movies. It also sends a directly-connected peer_id a custom message, containing a request to run method (with an optional dictionary of params); generally the peer will only allow you to run a command if it has provided you with a rune which allows it.

  • peer_id (pubkey): Peer to command.
  • method (string): Method to invoke on peer.
  • params (one of, optional):
    • (array): Array of positional parameters.
    • (object): Parameters for method.:
  • rune (string, optional): Rune to authorize the command.
  • filter (object, optional): Filter to peer to apply to any successful result.:

RETURN VALUE

On success, the return depends on the method invoked.

ERRORS

On failure, one of the following error codes may be returned:

  • -32600: Usually means peer is not connected
  • 19535: the local commando plugin discovered an error.
  • 19536: the remote commando plugin discovered an error.
  • 19537: the remote commando plugin said we weren't authorized.

It can also fail if the peer does not respond, in which case it will simply hang awaiting a response.

AUTHOR

Rusty Russell <[email protected]> wrote the original Python commando.py plugin, the in-tree commando plugin, and this manual page.

Christian Decker came up with the name "commando", which almost excuses his previous adoption of the name "Eltoo".
