NAME

ejabberdctl --- a control interface of ejabberd Jabber/XMPP server

 

SYNOPSIS

ejabberdctl [--node nodename] [--auth user host password] [command [options]]

 

DESCRIPTION

ejabberdctl is a front end to the ejabberd Jabber/XMPP server. It is designed to help the administrator control the functioning of the running ejabberd daemon.

This command must be run either by a superuser or by the user ejabberd, otherwise it will fail to start or to connect to the ejabberd instance.

 

OPTIONS

--node nodename
Specifies remote Erlang node to connect to. Default value is ejabberd. If the node name does not contain a symbol @ then the actual node name becomes node@host where host is short hostname (usually it coincides with `hostname -s`). If the node name contains a symbol @ and its hostname part is a FQDN then ejabberd will use so-called long names (see erl(1) manual page and look for options -name and -sname for details).

Examples of --node option:

ejabberd Connect to locally run ejabberd server at node ejabberd@`hostname -s`.

ejabberd@otherhost Connect to remotely run ejabberd server at node ejabberd@otherhost.

ejabberd@localhost Connect to locally run ejabberd server at node ejabberd@localhost.

ejabberdctl honors ERLANG_NODE environment variable from /etc/default/ejabberd, see below.

--auth user host password
If restriction of access to ejabberdctl commands is configured (see the "Restrict Execution with AccessCommands" section in the Installation and Operation Guide), this option must be used to authenticate the entity requesting execution of the command. user and host are the respective parts of the entity JID and password is either a plain text password to authenticate that JID or the MD5 hash of that password.

--concurrent
Due to the way ejabberdctl is implemented, it is normally not possible to run two instances of it in parallel-the second one will fail. This is OK in a common case when ejabberdctl is only run manually from time to time by a server administrator; if, conversely, there is a chance for several instances of ejabberdctl to be active at the same time (say, automated registration of new users on an actively used site), you can pass the --concurrent option to ejabberdctl which will ensure no clash will ever occur.
Usage of the --concurrent option creates additional pressure on the server resources, and that is why the behaviour it implements is not the default. This issue is described in more detail in /usr/share/doc/ejabberd/README.Debian
Note that the semantics of this option can be changed in a future release.

 

COMMANDS

Some commands to ejabberdctl are single words, like status, and some are multi-word, like reopen-log; to join the adjacent words of the multi-word commands you can use either the underline ("_") symbol or the minus sign ("-") or a mixture of them, so all the following forms are valid: status_list_host, status-list-host, status_list-host.

When run without any command specified, ejabberdctl prints the list of available commands and their short descriptions.

The following commands can be used:

help [--tags [tag] | PATTERN]
The help command without any options does the same thing as running ejabberdctl without any command specified --- it prints the list of available commands along with their short descriptions.
The --tags option specified alone makes the help command print the list of supported "help tags" which group ejabberdctl commands on the basis of their purpose (such as debugging commands, backup commands etc).
The --tags option specified with a tag tag makes the help command print the list of commands associated wih the help tag tag along with their short descriptions.
If the help command is followed by a word other than "--tags", this word is interpreted as a pattern specifying a set of commands to print the help on. In this pattern, a "*" character matches any number of characters, including zero, and a "?" character matches any single character. Note that when running ejabberdctl with this form of the help command from the shell, you have to protect the characters in the pattern from being interpreted by the shell.
debug
Attache an interactive Erlang shell to a running ejabberd server. To detach it press Ctrl+G, then input a character "q" and hit <Return>.
status
Request status of the Erlang virtual machine where ejabberd server is running.
stop
Stop the ejabberd server and its Erlang virtual machine.
stop-kindly delay announcement
Broadcast an announcement announcement to all connected users, wait delay seconds and then stop the ejabberd server and its Erlang virtual machine.
This command is interactive: it dumps the progress of the shutdown sequence to stdout (including waiting for the grace period to pass).
The announcement string is unconditionally interpreted as a sequence of UTF-8 characters no matter what locale settings the server and ejabberdctl processes see.
restart
Restarts the ejabberd server inside Erlang virtual machine. Note that if you want to change VM options (enable/disable kernel poll or SMP, increase number of ports or database tables) you have to stop ejabberd completely and then start it again.
reopen-log
Force the ejabberd server to reopen its log files (/var/log/ejabberd/ejabberd.log and /var/log/erlang.log by default). If module mod_http_fileserver is loaded then force the ejabberd server to reopen its weblog file.
register user server password
Register user user with password password at ejabberd virtual host server.
unregister user server
Unregister user user at ejabberd virtual host server.
backup filepath
Backup user database of the ejabberd server to file filepath.
The directory in which filepath is located must be writable by the user "ejabberd".
restore filepath
Restore user database of the ejabberd server from backup file filepath.
The file filepath must be readable by the user "ejabberd".
install-fallback filepath
Install a backup to filepath as fallback. The fallback will be used to restore the database at the next start-up.
The directory in which filepath is located must be writable by the user "ejabberd".
dump filepath
Dump user database of the ejabberd server to text file filepath.
The directory in which filepath is located must be writable by the user "ejabberd".
load filepath
Restore user database of the ejabberd server from text file filepath.
The file filepath must be readable by the user "ejabberd".
dump-table file table
Dump the specified database table to the specified text file.
The directory in which file is located must be writable by the user "ejabberd".
import-file filepath
Import user data from jabberd 1.4 spool file filepath. For example, if filepath is .../example.org/user.xml then imported username will be user and it will be imported to virtual server example.org.
The file filepath must be readable by the user "ejabberd".
import-dir directorypath
Import user data from jabberd 1.4 spool directory directorypath. Directory name should be the name of virtual server to import users.
The directory directorypath and the files in it must be readable by the user "ejabberd".
mnesia-change-nodename oldnodename newnodename oldbackup newbackup
Reads the backup file oldbackup (which should have been created using the ejabberdctl backup command) and writes its contents to the file newbackup while replacing in it all occurences of the Erlang node name oldnodename with the newnodename.
This should be used to "migrate" the ejabberd database to the new hostname of the machine on which ejabberd runs in case this hostname is about to change. This is because ejabberd is actually served by an Erlang node which is bound to the name of the physical host to provide for clustering.
rename-default-nodeplugin
Since release 2.0.0 and up to release 2.1.0, the implementation of publish-subscribe (pubsub) in ejabberd used a plugin named "node_default" as the default node plugin. Starting from release 2.1.0 this functionality is provided by the new plugin named "hometree". In the case of upgrading from an older version of ejabberd, its pubsub database might retain references to the old name of this plugin, "node_default", and this command can be used to upgrade the pubsub database, changing all these references to the new name - "hometree".
Note that ejabberd automatically runs this command if you update from an ejabberd release 2.0.5 or older.
Running this command on already updated database does nothing.
delete-expired-messages
Delete expired offline messages from ejabberd database.
delete-old-messages n
Delete offline messages older than n days from ejabberd database.
mnesia info
Show some information about the Mnesia system (see mnesia(3), function info).
mnesia
Show all information about the Mnesia system, such as transaction statistics, database nodes, and configuration parameters (see mnesia(3), function system_info).
mnesia key

incoming-s2s-number
Print number of incoming server-to-server connections to the node.
outgoing-s2s-number
Print number of outgoing server-to-server connections from the node.
user-resources user server

EXPORTING DATA TO PIEFXIS (XEP-0227) FORMAT

The commands described in this section require availability of the exmpp library which is not shipped with ejabberd. Your can download its source code from http://exmpp.org.

export-piefxis dir

The directory dir must be writable by the user "ejabberd".
export-piefxis-host dir host
Export data of all the users registered on the specified virtual host host to a set of PIEFXIS files which will be stored in the directory dir.
The directory dir and the files in it must be readable by the user "ejabberd".
import-piefxis file
Import users' data from a PIEFXIS file file.
The file file must be readable by the user "ejabberd".

 

EXTRA OPTIONS

An optional module mod_admin_extra adds a number of other commands.

While it is enabled by default, you might want to check it is actually enabled in the configuration file (especially if you're upgrading from pre-2.1 series of ejabberd).

To enable these additional commands add mod_admin_extra to the {modules} section of ejabberd config file and make it looking as the following:

{modules,
 [
  ...
  {mod_admin_extra, []},
  ...
 ]}.

Most of additional commands possess extended descriptions which can be printed using ejabberdctl help command

The new commands are:

add-rosteritem localuser localserver user server nick group subscription
Add to the roster of the user localuser registered on the virtual host localserver a new entry for the user user on the server server, assign the nickname nick to it, place this entry to the group group and set its subscription type to subscription which is one of "none", "from", "to" or "both".

delete-rosteritem localuser localserver user server
Delete from the roster of the user localuser on the server localserver an entry for the JID user@server.

ban-account user host reason
Ban the user user registered on the virtual host host. This is done by kicking their active sessions with the reason reason and replacing their password with a randomly generated one.

kick-session user host resource reason
Kick the session opened by the user user registered on the virtual host host and having the resource resource bound to it providing the reason reason.

change-password user host newpass
Change password of the user user registered on the virtual host host to newpass.

check-account user host
Exit with code 0 if the user user is registered on the virtual host host, exit with code 1 otherwise.

check-password user host password
Exit with code 0 the user user registered on the virtual host host has password password, exit with code 1 otherwise.

check-password-hash user host passwordhash hashmethod
Exit with code 0 if the user user registered on the virtual host host has a password, the hash of which, calculated using the hashmethod is equal to the hash passwordhash; exit with code 1 otherwise.
Allowed hashing methods are "md5" and "sha" (for SHA-1).

compile file
Compile and reload the Erlang source code file file.
The file file must be readable by the user "ejabberd".

load-config file
Load ejabberd configuration from the file file.
The file file must be readable by the user "ejabberd".
Note that loading config to a database does not mean reloading the server --- for example it's impossible to add/remove virtual hosts without server restart. In fact, only ACLs, access rules and a few global options are applied upon reloading.

delete-old-users days
Delete accounts and all related data of users who did not log on the server for days days.

delete-old-users-vhost host days
Delete accounts and all related data of users registered on the virtual host host who did not log on the server for days days.

The available values for the status parameter are the same as of the status-list subcommand.

status-num-host host status
Print the number of users currently logged into the server which are registered on the virtual host host and have the presence status status.
The available values for the status parameter are the same as of the status-list subcommand.

user-sessions-info user server

For each session, one line of output is generated, containing the following fields separated by tab characters: connection string (such as "c2s", "c2s_tls" etc), remote IP address, remote port number, priority of the resource bound to this session, name of an Erlang node serving the session, session uptime (in seconds), resource string.

 

NOTES

ejabberdctl starts distributed Erlang node ejabberddebug (if run with debug option) or ejabberdctl (if run with any other options). If the ejabberd server's node name to connect to includes FDQN as a hostname Erlang option -name is used. Otherwise ejabberdctl uses short names (-sname option).

Note that ejabberdctl does not append hostname to its own node name leaving this to Erlang emulator. It usually follows `hostname -f` to find a hostname if long names are used or `hostname -s` in case of short names, but may fail in case of unusual networking settings. A known case of failure is using long names when `hostname -f` doesn't return FDQN. If ejabberdctl cannot create Erlang node then it cannot control ejabberd server.

ejabberdctl does not do anything by itself except for connecting to the running ejabberd instance and telling it about the action requested by the user. Hence all the ejabberdctl's operations involving writing or reading files or directories are actually performed by the server process which runs with the uid and gid of the user and group "ejabberd", respectively. This must be taken into account when requesting such operations to be done.

 

OPTIONS FILE

The file /etc/default/ejabberd contains specific options. Two of them are used by ejabberdctl.

ERLANG_NODE
Use specified string as Erlang node of ejabberd server to connect. It overrides default ejabberd node name. The string may take one of the following forms: nodename, nodename@hostname or nodename@hostname.domainname.

FIREWALL_WINDOW
Use the specified range of ports to communicate with the other Erlang nodes (namely, with the target Erlang node running ejabberd). This can be useful when the system running the target node has restricted firewall setup allowing only a certain range of ports to be used by the Erlang nodes for communication; in this case, you should specify that range of ports in the FIREWALL_WINDOW setting.
