Welcome to Tigase Socks5 Proxy guide

Tigase SOCKS5 component allows for file transfers to be made over a SOCKS5 proxy in accordance with XEP-0065 SOCKS5 Bytestreams. This allows for some useful features such as: - transfer limits per user, domain, or global - recording transfers between users - quotas and credits system implementation

Overview

Tigase Socks5 Proxy is implementation of Socks5 proxy described in XEP-0065: SOCKS5 Bytestreams, in section 6. Mediated Connection which provides support for Socks5 proxy for file transfers between XMPP client behind NATs to Tigase XMPP Server.

Installation

Tigase SOCKS5 component comes built into the dist-max archives for Tigase XMPP server, and requires the component to be listed in config.tdsl file:

proxy {}

You will also need to decide if you wish to use database-based features or not. If you wish to simply run the socks5 proxy without features such as quotas, limits add the following line:

proxy {
    'verifier-class' = 'tigase.socks5.verifiers.DummyVerifier'
}

This will enable the SOCKS5 Proxy without any advanced features. If you wish to use those features, see the configuration section below.

Database Preparation

In order to use the more advanced features of the SOCKS5 Proxy Component, your database needs to be prepared with the proper schema prior to running the server.

You may either edit an existing database, or create a new database for specific use with the Proxy.

Edit Existing Database

You can add the proper schema to your existing database using the DBSchemaLoader utility included with Tigase. The database folder contains the schema file for your type of database.

First, backup your database before performing any actions and shut down Tigase XMPP Server.

Then from the Tigase installation directory run the following command:

java -cp "jars/*" tigase.db.util.DBSchemaLoader -dbType {derby,mysql,postgresql,sqlserver} - dbHostname {db address} -dbName {dbname} -rootUser root -rootPass root -file database/{dbtype}-socks5-schema.sql

You should see the following dialogue

LogLevel: CONFIG
tigase.db.util.DBSchemaLoader     	 <init>          	 CONFIG     Properties: [{dbHostname=localhost, logLevel=CONFIG, dbType=derby, file=database/derby-socks5-schema.sql, rootUser=root, dbPass=tigase_pass, dbName=tigasedb, schemaVersion=7-1, rootPass=root, dbUser=tigase_user}]
tigase.db.util.DBSchemaLoader     	 validateDBConnection 	 INFO       Validating DBConnection, URI: jdbc:derby:tigasedb;create=true
tigase.db.util.DBSchemaLoader     	 validateDBConnection 	 CONFIG     DriverManager (available drivers): [[jTDS 1.3.1, org.apache.derby.jdbc.AutoloadedDriver@34a245ab, com.mysql.jdbc.Driver@3941a79c, org.postgresql.Driver@6e2c634b]]
tigase.db.util.DBSchemaLoader     	 validateDBConnection 	 INFO       Connection OK
tigase.db.util.DBSchemaLoader     	 validateDBExists 	 INFO       Validating whether DB Exists, URI: jdbc:derby:tigasedb;create=true
tigase.db.util.DBSchemaLoader     	 validateDBExists 	 INFO       Exists OK
tigase.db.util.DBSchemaLoader     	 loadSchemaFile  	 INFO       Loading schema from file: database/derby-socks5-schema.sql, URI: jdbc:derby:tigasedb;create=true
tigase.db.util.DBSchemaLoader     	 loadSchemaFile  	 INFO        completed OK
tigase.db.util.DBSchemaLoader     	 shutdownDerby   	 INFO       Validating DBConnection, URI: jdbc:derby:tigasedb;create=true
tigase.db.util.DBSchemaLoader     	 shutdownDerby   	 WARNING    Database 'tigasedb' shutdown.
tigase.db.util.DBSchemaLoader     	 printInfo       	 INFO

One this process is complete, you may begin using SOCKS5 proxy component.

Create New Database

If you want to create a new database for the proxy component and use it as a separate socks5 database, create the database using the appropriate schema file in the database folder. Once this is created, add the following line to your config.tdsl folder.

proxy {}

For example, a mysql database will have this type of URL: jdbc:mysql://localhost/SOCKS?user=root&password=root to replace database URL. For more options, check the database section of this documentation.
