jabber.xml(5) 1.4.4 jabber.xml(5) jabberd14 project jabberd14 project 15 Mar 2005 NAME jabber.xml - jabberd daemon configuration file SYNOPSIS The jabber daemon jabberd is configured by an XML configuration file. By default jabberd will read /usr/local/etc/jabber.xml. The -c command line option can be used to specify an alternate configuration file. FILE FORMAT The configuration file has to be a valid XML document preferably in the UTF-8 charset (ASCII is valid subset of UTF-8). <jabber/> This is the root element of the configuration file. <service/> This element is an immediate child element of the <jabber/> root element. It defines a general purpose component in the jabber daemon. The jabber daemon will route all stanzas to this component that have a domain part in the destination JID that equals the id attribute or any defined additional domains this component is responsible for using the <host/> child element. An implementation or relation to an other process is defined using one of the following child elements: <accept/>, <connect/>, <dynamic/>, <exec/>, <load/>, <null/>. Any child elements in own namespaces are ignored by the core jabberd and can be used by components to store their own configuration. <xdb/> This element is an immediate child element of the <jabber/> root element. It defines a component in the jabber daemon, that is responsible for XML data storage. This components internal address is defined by the id attribute. The <host/> child elements define for which domains this storage component is managing the data. An empty <host/> element defines, that it is responsible for all components. With the <ns/> child element you can limit the responsibility to XML chunks in a given set of namespaces. You can then for example define one storage component that handles rosters and an other that handles offline message storage. An implementation or relation to an other process is defined using on of the following child elements: <accept/>, <connect/>, <dynamic/>, <exec/>, <load/>, <null/>. Any child elements in own namespaces are ignored by the core jabberd and can be used by components to store their own configuration. <log/> This element is an immediate child element of the <jabber/> root element. It defines a component in the jabber daemon, that acts as a logging sink. This components internal address is defined - 1 - Formatted: December 27, 2024 jabber.xml(5) 1.4.4 jabber.xml(5) jabberd14 project jabberd14 project 15 Mar 2005 by the id attribute. The <host/> child elements define for which domains this logging sink is logging messages. An empty <host/> element defines, that it is responsible for all components. With the <logtype/> child element you can select the types of messages, that are handled by this component. Where to write the logging information is defined with one of the following child elements: <file/>, <stderr/>, <stdout/>, <to/>. With the <format/> child element you define the format of the logged message. <io/> This element is an immediate child element of the <jabber/> root element. In this section of the configuration file you can define different settings that are related to the network I/O layer. This includes bandwidth limitations (using the <karma/> element), assigning X.509 certificates to sockets (using the <ssl/> element), and to limit access to the server to specific IP address ranges (using the <allow/> and <deny/> elements). <pidfile/> This element specifies to which file the server should write its process ID. If this file already exists when the server is started, it will fail. You have to remove stale pidfiles before starting the server yourself. If you omit this element, the server will not write nor check any pidfile. <debug/> This element contains configuration settings controlling the output of debugging messages. These settings can be changed at server runtime, the server will reread them on receiving a SIGHUP signal. The following elements are used inside the <service/>, <xdb/>, and <log/> elements, that are defining components. They are used to provide the jabberd process with information where it can find the component's implementation. <load/> This element can be used inside any component definition. It specifies, that the implementation of the component can be found inside a shared object. Any child element of this element defines a shared object file and a method in this object. jabberd will load the shared object files which locations are defined in the cdata elements inside the child elements, the names of the elements are defining the functions that have to be called. An optional main attribute in the <load/> element define the main function in a component, that has to be used to initialize it. <accept/> - 2 - Formatted: December 27, 2024 jabber.xml(5) 1.4.4 jabber.xml(5) jabberd14 project jabberd14 project 15 Mar 2005 This element defines, that jabberd will wait for an incoming connection using the jabber:component:accept protocol defined in JEP-0114. With this it is possible to run components in their own process, even on different hosts and connect it to the main jabberd routing process. On the other end of the connection there can be an instance of jabberd again that uses a section with <connect/> to initiate the connection, but there are libraries in many programming languages available, that implement JEP-0114 as well. Inside this element you have to provide an <ip/> element, that defines the IPv4 or IPv6 address to listen on, a <port/> element that defines on which port the server will listen for the connection, and a <secret/> element, that defines a shared secret to authenticate the other peer. <connect/> This element is the opposite of the <accept/> element. Jabberd will try to connect to an implementation of the jabber:component:accept protocol defined in JEP-0114. Inside this element you have to provide an <ip/> element, that defines the IPv4 or IPv6 address where to connect to, a <port/> element, that defines the destination port, and a <secret/> element, that defines a shared secret to authenticate to the other peer. <dynamic/> This element defines a directory where components reside. Incoming packets are routed to the components based on the node or resource part of the JabberID. The files in this directory can be shared objects or executables. This is rarely used and badly tested. <exec/> This element is used to start an external component. Instead of using a TCP socket to communicate with it, the jabberd process will execute the component and communicate with it using pipes on stdin and stdout. <file/> This element can only be used inside a <log/> section. It is used to specify that log messages should be appended to a text file. <null/> This element specifies an empty component. Everything that is sent to a JabberID with the domain part of this component is silently discarded. It can be used to drop stanzas directed to entities on the Jabber network, that have disappeared (e.g. update.jabber.org). <stderr/> This element can only be used inside a <log/> section. It is used - 3 - Formatted: December 27, 2024 jabber.xml(5) 1.4.4 jabber.xml(5) jabberd14 project jabberd14 project 15 Mar 2005 to specify that log messages should be written to the standard error output stream. <stdout/> This element is used to define, that the jabberd process is communicating with the process, that is implementing the component. It is the opposite of <exec/>. A process that is started by <exec/> in an other process can use <stdout/> to implement the other end of the connecting pipe. <syslog/> This element can only be used inside a <log/> section. It is used to specify that log messages should be written to the syslog. <to/> This element can only be used inside a <log/> section. It is used to reformat log packets as messages and resend them to an entity with the given JabberID. The JabberID is given as cdata child element. <unsubscribe/> This element can only be used inside a <service/> section. It is used to bounce messages and iq queries and send unsubscribes to presences, that are received. It is intended to be used as a replacement for transports, that are removed from a server. It will remove the roster items of this transport from the users' rosters. AUTHOR Jabber Software Foundation - 4 - Formatted: December 27, 2024
