lightning-ping -- Command to check if a node is up. ============================================================ SYNOPSIS -------- **ping** *id* [*len*] [*pongbytes*] DESCRIPTION ----------- The **ping** command checks if the node with *id* is ready to talk.

EXAMPLE JSON RESPONSE ----- ```json { "totlen": 132 } ``` AUTHOR ------ Vincenzo Palazzo <> wrote the initial version of this man page, but many others did the hard work of actually implementing this rpc command.
