Spectrum 2 setup guide for beginners

I’ve created this guide to help beginners like me setup Spectrum 2. If you don’t know what Spectrum 2 is, use this link to learn more about it. If you already know about XMPP and Spectrum 2, the official documentation will be better suited for you.

Requirements

I’m pretty sure these steps can be applied to any linux distribution but I’ll be using Debian Jessie

Configuration of Prosody

Server setup

To configure Prosody would need to edit the default configuration file located at /etc/prosody/prosody.cfg.lua.

First you’ll need to create a VirtualHost, this will be used later on by the different accounts on the server. To create a VirtualHost, head close to the end of the file and you will see a line written VirtualHost "localhost". You can rename localhost to anything you want, for the purpose of this guide I will rename it to server so the result will be VirtualHost "server".

After this you’ll need to add an admin account for the server. This can be done by adding an account to the admins list at the beginning of the file. The line look like this admins = { } and the the way the account is added is by writing the ID of the account like this *username*@*domain* where domain is the VirtualHost created earlier and username a username of you choice. The line should look like this at the end, admins = { "[email protected]" }

The last things to add to the configuration file are external components for the different Spectrum services we plan to use. To this, go to the end of the file and add these lines:

Component "name-of-service.domain"
	component_secret "magicalpassword"

In this case if I wanted to run a Twitter transport, the component would be,

Component "twitter.server"
	component_secret "magicaltwitterpassword"

The component_secret is a password for the Twitter transport and not the actual password of the Twitter account you plan to use. Everything should be okay now and the only thing left to do with Prosody is to create the accounts on the server.

Account creation

To create an account on the Prosody server you’ll need to use the prosodyctl command. First, let’s add the admin account define in the admins list by typing sudo prosodyctl adduser [email protected], this account will be available for administrative purposes only and won’t really be used to connect to services using an XMPP client.

You can now created an account for one of the components you added to the /etc/prosody/prosody.cfg.lua file. For the Twitter transport, a simple account like [email protected] can be used. DO NOT USE something like twitteruser@twitter.server it won’t work.

Configuration of Spectrum 2

Before creating configuration files for the Spectrum 2 transports, create a new UNIX user named spectrum. This use will execute the transports. After creating it, simply type to sudo su spectrum to log as this user.

This is an example of a transport config file located at /etc/spectrum2/transports, the file should end with .cfg. In this case, this file would be called twitter.cfg and it’s full path would be /etc/spectrum2/transports/twitter.cfg.
