It may be +used to control the server daemon and manage users. + +prosodyctl needs to be executed with sufficient privileges to perform +its commands. This typically means executing prosodyctl as the root +user.

You will be prompted + to enter the user's password. + +passwd jid +: Changes the password of an existing user with Jabber ID, jid. You + will be prompted to enter the user's new password. + +deluser jid +: Deletes an existing user with Jabber ID, jid, from the server. + +Daemon Management +----------------- + +Although prosodyctl has commands to manage the prosody daemon it is +recommended that you utilize your distributions daemon management +features if you attained Prosody through a package. + +To perform daemon control commands prosodyctl needs a pidfile value +specified in `/etc/prosody/prosody.cfg.lua`. Failure to do so will cause +prosodyctl to complain. + +start +: Starts the prosody server daemon. If run as root prosodyctl will + attempt to change to a user named "prosody" before executing. This + operation will block for up to five seconds to wait for the server + to execute. + +stop +: Stops the prosody server daemon.

Equivalent to running prosodyctl + stop followed by prosodyctl start. + +reload +: Signals the prosody server daemon to reload configuration and reopen + log files. + +status +: Prints the current execution status of the prosody server daemon. + +Certificates +------------ + +prosodyctl can create self-signed certificates, certificate requests and +private keys for use with Prosody. Commands are of the form +`prosodyctl cert subcommand`. Commands take a list of hosts to be +included in the certificate. + +`request hosts` +: Create a certificate request (CSR) file for submission to a + certificate authority. Multiple hosts can be given, sub-domains are + automatically included. + +`generate hosts` +: Generate a self-signed certificate. + +`key host [size]` +: Generate a private key of 'size' bits (defaults to 2048). Invoked + automatically by 'request' and 'generate' if needed. + +`config hosts` +: Produce a config file for the list of hosts.
