OTalk XMPP Server

Any XMPP server that supports websockets would work, but Prosody also supports some extra features that makes OTalk nicer to use, like message archiving.

Installation

1. Install Prosody. We want to use message archiving, which requires trunk for now.

    sudo apt-get install prosody-trunk
   

2. Install additional dependencies

    sudo apt-get install lua-zlib
    sudo apt-get install lua-sec-prosody
    sudo apt-get install lua-dbi-sqlite3
    sudo apt-get install liblua5.1-bitop-dev
    sudo apt-get install liblua5.1-bitop0 
   

3. Install the included modules

    sudo cp -r mod_carbons /usr/lib/prosody/modules
    sudo cp -r mod_mam /usr/lib/prosody/modules
    sudo cp -r mod_smacks2 /usr/lib/prosody/modules
    sudo cp -r mod_smacks3 /usr/lib/prosody/modules
    sudo cp -r mod_websocket /usr/lib/prosody/modules
   

4. Configure Prosody

    sudo cp prosody.cfg.lua /etc/prosody/
   

5. Allow access to port 5281. Proxying to hide the port would be best (eg, use wss://HOST/xmpp-websocket).

To use &yet authentication

1. Install external auth module

    sudo cp -r mod_auth_external /usr/lib/prosody/modules
   

2. Modify Prosody config

    VirtualHost "HOST"
        authentication = "external"
        external_auth_command = "andyet-prosody-auth"
   

3. Install andyet-prosody-auth

    npm install -g andyet-prosody-auth
   

4. Create /etc/prosody/andyet.json.

    {
        "bucker": {
            "file": {
                "filename": "/var/log/prosody/auth.log"
            }
            "console": false
        },
        "andyetAuth": {
            "id": "CLIENT ID",
            "secret": "CLIENT SECRET"
        },
        "andyetAPIs": {
            "apps": "https://apps.andyet.com",
            "shippy": "https://api.andbang.com"
        }
    }
   

   NOTE: the "console": false configuration MUST be included for bucker so that log output does not get sent to Prosody instead of the success/failure tokens.
