Usage
|
|
|
|
radicle-node [<option>...]
|
|
|
|
If you're running a public seed node, make sure to use `--listen` to bind a listening socket to
|
|
eg. `0.0.0.0:8776`, and add your external addresses in your configuration.
|
|
|
|
Options
|
|
|
|
--config <path> Config file to use (default ~/.radicle/config.json)
|
|
--force Force start even if an existing control socket is found
|
|
--listen <address> Address to listen on
|
|
--version Print program version
|
|
--help Print help
