Linux DEB and RPM Installers – Download ejabberd for windows 32 bit
This module should be disabled for instances of ejabberd with hundreds of thousands users. With this module enabled, services on your server can be discovered by XMPP clients. Accordingly, XMPP clients need to have support for the newer Service Discovery protocol if you want them be able to discover the services you offer.
This module simply echoes any XMPP packet back to the sender. This mirror can be of interest for ejabberd and XMPP client debugging. In this example a new content type ogg is defined, png is redefined, and jpg definition is deleted. To use this module you must enable it:.
It can be used to discover when a disconnected user last accessed the server, to know when a connected user was last active on the server, or to query the uptime of the ejabberd server. Users can discover existing rooms, join or create them. Occupants of a room can chat in public or have private chats. This module supports clustering and load balancing.
One module can be started per cluster node. Rooms are distributed at creation time on all available MUC module instances. The multi-user chat module is clustered but the rooms themselves are not clustered nor fault-tolerant: if the node managing a set of rooms goes down, the rooms disappear and they will be recreated on an available node on first connection attempt. Once you enable this module, users can join a room using a MUC capable XMPP client, and if they have enough privileges, they can request the configuration form in which they can set the option to enable room logging.
This module implements offline message storage XEP This means that all messages sent to an offline user will be stored on the server until that user comes online again.
Thus it is very similar to how email works. Note that ejabberdctl has a command to delete expired messages see section 4. This example allows power users to have as much as offline messages, administrators up to , and all the other users up to When this module is enabled ejabberd responds correctly to ping requests, as defined in the protocol. This example enables Ping responses, configures the module to send pings to client connections that are inactive for 4 minutes, and if a client does not answer to the ping in less than 32 seconds, its connection is closed:.
If a user sends or receives more of those stanzas in a time interval, the exceeding stanzas are silently dropped, and warning is logged. This example enables the module, and allows up to 5 presence subscription stanzas to be sent or received by the users in 60 seconds:.
If end users have support for it in their XMPP client, they will be able to:. It allows ejabberd to act as a file transfer proxy between two XMPP clients. The “virtual” nodetree does not store nodes on database. This saves resources on systems with tons of nodes. If using the “virtual” nodetree, you can only enable those node plugins: [“flat”,”pep”] or [“flat”]; any other plugins configuration will not work.
Also, all nodes will have the defaut configuration, and this can not be changed. Using “virtual” nodetree requires to start from a clean database, it will not work if you used the default “tree” nodetree before. In that case you should also add “dag” node plugin as default, for example: plugins: [“dag”,”flat”,”hometree”,”pep”]. Example of configuration that uses flat nodes as default, and allows use of flat, nodetree and pep nodes:.
Only flat, hometree and pep plugins supports ODBC. The following example shows previous configuration with ODBC usage:. This protocol enables end users to use a XMPP client to:. This option limits the frequency of registration from a given IP or username. The timeout is expressed in seconds, and it must be an integer. To disable this limitation, instead of an integer put a word like: infinity. Default value: seconds.
For example, the users of the host example. This example configuration enables Roster Versioning with storage of current id. With this example configuration, only admins can manage their rosters; everybody else cannot modify the roster:. This module adds support for logging end user packets via a XMPP message auditing service such as Bandersnatch. This module enables you to create shared roster groups.
This means that you can create groups of people that can see members from other groups in their rosters. The big advantages of this feature are that end users do not need to manually add all users to their rosters, and that they cannot permanently delete users from the shared roster groups. A shared roster group can have members from any XMPP server, but the presence will only be available from and to members of the same virtual host where the group is created.
Shared roster groups can be edited only via the Web Admin. Each group has a unique identification and the following parameters:. The module accepts the following configuration parameters. Some of them, if unspecified, default to the values specified for the top level of configuration. This lets you avoid specifying, for example, the bind password, in multiple places. These parameters specify LDAP filters used to query for shared roster information. Note that you will probably need to manually define the User and Group Filter s since the auto-assembled ones will not work if:.
A symptom of this problem is that you will see messages such as the following in your slapd. These parameters specify the names of the attributes which hold interesting data in the entries returned by running filters specified in section 3.
The name of the attribute differs depending on the objectClass you use for your group objects, for example:. Also, in the last two cases an error message is logged during the module initialization. The module also accepts the connection parameters, all of which default to the top-level parameter of the same name, if unspecified. See 3. When the module is called to retrieve the shared roster for a user, the following algorithm is used:.
This step is here for historical reasons. Since there are many possible DIT layouts, it will probably be easiest to understand how to configure the module by looking at an example for a given DIT or one resembling it.
This seems to be the kind of DIT for which this module was initially designed. Basically there are just user objects, and group membership is stored in an attribute individually for each user. For example in a layout shown in figure 3. This however seems to be a common DIT layout, so the module keeps supporting it.
You can use the following configuration…. This type of DIT contains distinctly typed objects for users and groups — see figure 3. This protocol enables a client to discover its external IP address. Note that it is not enough to just load this module only. You should also configure listeners and DNS records properly. This protocol allows you to retrieve next statistics from your ejabberd deployment:.
As there are only a small amount of clients for example Tkabber and software libraries with support for this XEP, a few examples are given of the XML you need to send in order to get the statistics. Here they are:. This module allows end users to store and retrieve their vCard, and to retrieve other users vCards, as defined in vcard-temp XEP The module also implements an uncomplicated Jabber User Directory based on the vCards of these users.
Moreover, it enables the server to send its vCard when queried. This module does not depend on the authentication method see 3. If one of these options is not set, ejabberd will look for the top-level option with the same name. The vCard-Based Avatars protocol XEP provides a method for clients to inform the contacts what is the avatar hash value.
However, simple or small clients may not implement that protocol. If this module is enabled, all the outgoing client presence stanzas get automatically the avatar hash on behalf of the client. So, the contacts receive the presence stanzas with the Update Data described in XEP as if the client would had inserted it itself. If the client had already included such element in the presence stanza, it is replaced with the element generated by ejabberd.
By enabling this module, each vCard modification produces a hash recalculation, and each presence sent by a client produces hash retrieval and a presence stanza rewrite. For this reason, enabling this module will introduce a computational overhead in servers with clients that change frequently their presence. With the ejabberdctl command line administration script you can execute ejabberdctl commands described in the next section, 4.
This means you can start, stop and perform many other administrative tasks in a local or remote ejabberd server by providing the argument –node NODENAME. The ejabberdctl script can be configured in the file ejabberdctl. This file includes detailed information about each configurable option. See section 4. The ejabberdctl script returns a numerical status code. Success is represented by 0 , error is represented by 1 , and other codes may be used for specific results. When ejabberdctl is executed without any parameter, it displays the available options.
If there is an ejabberd server running in the system, ejabberdctl shows the ejabberdctl commands described bellow and all the ejabberd commands available in that server see 4. The ejabberdctl script can be restricted to require authentication and execute some ejabberd commands ; see 4. Add the option to the file ejabberd. In this example there is no restriction:. If account robot1 example.
This system is configured using environment variables and command line parameters. The ejabberdctl administration script uses many of those possibilities.
You can configure some of them with the file ejabberdctl. This section describes for reference purposes all the environment variables and command line parameters. You can find other options in the Erlang manual page erl -man erl. Those commands can be defined in any Erlang module and executed using any valid frontend. When more modules are installed, new commands may be available in the frontends.
The easiest way to get a list of the available commands, and get help for them is to use the ejabberdctl script:. The frontends can be configured to restrict access to certain commands. In that case, authentication information must be provided. In each frontend the AccessCommands option is defined in a different place. But in all cases the option syntax is the same:. The default value is to not define any restriction: [].
The authentication information is provided when executing a command, and is Username, Hostname and Password of a local XMPP account that has permission to execute the corresponding command.
This means that the account must be registered in the local ejabberd, because the information will be verified.
When one or several access restrictions are defined and the authentication information is provided, each restriction is verified until one matches completely: the account matches the Access rule, the command name is listed in CommandNames, and the provided arguments do not contradict Arguments.
This list of access restrictions allows only robot1 example. The ejabberd Web Admin allows to administer most of ejabberd using a web browser. You will be asked to enter the username the full Jabber ID and password of an ejabberd user with administrator rights.
After authentication you will see a page similar to figure 4. The access rule configure determines what accounts can access the Web Admin and modify it. Certain pages in the ejabberd Web Admin contain a link to a related section in the ejabberd Installation and Operation Guide. Being distributed, Mnesia enforces consistency of its file, so it stores the name of the Erlang node in it see section 5.
The name of an Erlang node includes the hostname of the computer. So, the name of the Erlang node changes if you change the name of the machine in which ejabberd runs, or when you move ejabberd to a different machine. You have two ways to use the old Mnesia database in an ejabberd with new node name: put the old node name in ejabberdctl.
Those example steps will backup, convert and load the Mnesia database. You need to have either the old Mnesia spool dir or a backup of Mnesia. If you already have a backup file of the old database, you can go directly to step 5.
You also need to know the old node name and the new node name. This small program is automatically started by Erlang, and is never stopped. To communicate with ejabberd , the script ejabberdctl starts a new Erlang node and connects to the Erlang node that holds ejabberd. In order for this communication to work, epmd must be running and listening for name requests in the port You should block the port in the firewall in such a way that only the programs in your machine can access it.
If you build a cluster of several ejabberd instances, each ejabberd instance is called an ejabberd node. Those ejabberd nodes use a special Erlang communication method to build the cluster, and EPMD is again needed listening in the port So, if you plan to build a cluster of ejabberd nodes you must open the port for the machines involved in the cluster. Once an Erlang node solved the node name of another Erlang node using EPMD and port , the nodes communicate directly.
The ports used in this case by default are random, but can be configured in the file ejabberdctl. The Erlang command-line parameter used internally is, for example:. It is also possible to configure in ejabberdctl.
The Erlang cookie is a string with numbers and letters. An Erlang node reads the cookie at startup from the command-line parameter -setcookie.
If this file does not exist, it is created immediately with a random cookie. Two Erlang nodes communicate only if they have the same cookie. Setting a cookie on the Erlang node allows you to structure your Erlang network and define which nodes are allowed to connect to which. Thanks to Erlang cookies, you can prevent access to the Erlang node by mistake, for example when there are several Erlang nodes running different programs in the same machine.
Setting a secret cookie is a simple method to difficult unauthorized access to your Erlang node. However, the cookie system is not ultimately effective to prevent unauthorized access or intrusion to an Erlang node. The communication between Erlang nodes are not encrypted, so the cookie could be read sniffing the traffic on the network. The recommended way to secure the Erlang node is to block the port An Erlang node may have a node name. The name can be short if indicated with the command-line parameter -sname or long if indicated with the parameter -name.
Using the option -sname instead of -name is a simple method to difficult unauthorized access to your Erlang node. However, it is not ultimately effective to prevent access to the Erlang node, because it may be possible to fake the fact that you are on another network using a modified version of Erlang epmd.
The file system permissions should be set to only allow the proper user to read, write and execute those files and directories. A XMPP domain is served by one or more ejabberd nodes. These nodes can be run on different machines that are connected via a network. This is needed because all nodes exchange information about connected users, s2s connections, registered services, etc…. This module is the main router of XMPP packets on each node.
It uses a global routing table. If not, it is sent to the s2s manager. If the destination JID has a non-empty user part, it is routed to the session manager, otherwise it is processed depending on its content.
This module routes packets to local users. It looks up to which user resource a packet must be sent via a presence table. Then the packet is either routed to the appropriate c2s process, or stored in offline storage, or bounced back. This module routes packets to other XMPP servers. If that is the case, the s2s manager routes the packet to the process serving this connection, otherwise a new connection is opened.
Suppose you already configured ejabberd on one machine named first , and you need to setup another one to make an ejabberd cluster.
Then do following steps:. This will start Mnesia serving the same database as ejabberd first. You should see a lot of remote tables and a line like the following:.
Note: the Mnesia directory may be different in your system. To know where does ejabberd expect Mnesia to be installed by default, call 4. Replicating a table makes lookups in this table faster on this node. Writing, on the other hand, will be slower. And of course if machine with one of the replicas is down, other replicas will be used. Also section 5. It means that you can plug one or several instances of the same component on each ejabberd cluster and that the traffic will be automatically distributed.
The default distribution algorithm try to deliver to a local instance of a component. If several local instances are available, one instance is chosen randomly. Discover the benefits BitlBee 3.
