Installation and operation guide for J2J (Jabber-to-Jabber) gateway.

Installation and configuring[edit]

Dependencies[edit]

For J2J you will need:

(Note: there is experimental Mysql with mysql-python support in 1.1.8 and beyond, see Changelog.txt)

Source code downloads[edit]

You need to get sources of J2J. You can do it at JRuDevels Downloads, or with help of SVN: 

svn co svn://svn.jrudevels.org/j2j/trunk j2j/

Database setup[edit]

You need to setup a database to work with J2J:

Let's create a database for J2J:

  • postgresql:
createdb j2j
  • mysql
mysql -h localhost -u root -p -e "CREATE DATABASE j2j;"

Let's create a DB user:

  • postgresql:
createuser -P j2j

A -P key means, that user is created with a password-prompt. Store it, because it will be needed for next steps. Same with yourpassword in mysql:

  • mysql:
mysql -h localhost -u root -p -e "GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP ON j2j.* TO 'j2j'@'localhost' IDENTIFIED BY 'yourpassword';"

And import a database structure:

  • postgresql:
psql -U j2j j2j
\i pgsql.schema
  • mysql
mysql -h localhost -u root -p -e "use j2j; \. mysql.schema"

Gateway configuration[edit]

Configuration file is needed for J2J. Default search paths for it is: ./j2j.conf, ~/.j2j/j2j.conf and /etc/j2j/j2j.conf; also you can use "-c /path/j2j.conf" in main.py, see later. Let's copy example of this and edit it: 

cp j2j.conf.example j2j.conf
nano -w j2j.conf

Parameters:

  • Section component
    • JID - JID of gateway. For example, 
JID=j2j.server.com
    • Host - IP or domain-name of your Jabber-server. For example,
Host="127.0.0.1"
    • Port - port on Jabber-server to which J2J will be connected. It must be the same as it specified in your Jabber-server's configuration.
    • Password - password on Jabber-server to which J2J will be connected.
  • Section database
    • Host - IP or Domain-name of your database server. Leave it blank to use postgres' UNIX-socket.
    • Type - Type of your database server: postgres or mysql
    • User - Database username (in our example is j2j)
    • Name - Database name (in our example is j2j)
    • Password - Password for this database username.
    • Prefix - pass it as is.
  • Section admins
    • List - a list of JIDs, for a notifications of new users registrations. For example,
List=vasya@server.ru,zhenya@server.com
  • Section debug
    • Pass it as is. If you will get errors in J2J's work try to turn on logging in it section.

Running[edit]

Let's start the gateway: 

python main.py

it should spit "Connected", see also your jabber server log.

Problems[edit]

  • If you see:
Exception exceptions.AttributeError: "database instance has no attribute 'dbCursor'" in <bound method
 database.__del__ of <database.database instance at 0x85f1bec>> ignored

Check if you have installed python db access support ( i.e. python-pygresql, python-mysqldb in debian) and if it is up to date. Otherwise, is postgresql/mysql rdbms accesible with the parameters in [database] section in your j2j.conf? is it up?

  • If you see :
Traceback (most recent call last):
  File "/usr/src//j2j/main.py", line 11, in ?
    import j2j
  File "/usr/src/j2j/j2j.py", line 14, in ?
    from client import Client
  File "/usr/src/j2j/client.py", line 10, in ?
    from twisted.names.error import DNSNameError
ImportError: No module named error

In debian etch twisted is too old: required twisted 8.01 is in etch+1; ubuntu 8.04 is ok too. And with FreeBSD you need also py-twistedNames, it's not installed with twisted.

  • Sometimes main.py doesn't spit nothing, check your jabber server log, maybe there is an authentication password problem so recheck [component] section in j2j.conf
  • In j2j.conf are declared some paths to log files, do these files exist? do they have write permissions?

Command line options[edit]

Start J2J with the --help key to get help about command-line options.
