First I need a server. A very popular server is GoogleTalk. But I am not in a Googly mood right now so first order of the day is to get a private server running.
I am setting up a Docker container on [[Bellman]] to run Openfire which (a few years ago anyway) I found to be the best option.
 
These instructions for setting up a Docker version are excellent: https://hub.docker.com/r/gizmotronic/openfire
 
My command is
docker run --name openfire -d --restart=always \
  --publish 9090:9090 --publish 5222:5222 --publish 7777:7777 \
  --volume /home/docker/volumes/openfire_xmpp:/var/lib/openfire \
  gizmotronic/openfire:4.2.3
 
To access the log file,
docker exec -it openfire tail -f /var/log/openfire/info.log
 
Shell access,
docker exec -it openfire bash
 
=== XMPP and your firewall ===


Requirements
Open port 5222 to allow normal messages to pass between client and server. If you have SSL installed use port 5223.
# Free
If you want server to server communications then open port 5269.
# Open source
# Runs on Linux

XMPP is the Jabber protocol. It was used for GoogleTalk once upon a time.

See here for official documentation or here for the Wikipedia page.

Currently I am looking for a way to send messages along to my phone from Twilio and they are dragging their feet on Whatsapp support. And I don't want to use SMS anymore, to avoid Ting charges.

I should use push messages (Amazon SNS or Twilio Notify which both wrap around Google) but I don't want to write a custom Android app today. If I use XMPP I think I can put a client on the phone and get started right away, today.

Use cases:

  • Gateway for SMS from Twilio to a smartphone or laptop.
  • AVL for FoxtrotGPS I want to be able to show the locations of "friends". Aka

"presence information" http://en.wikipedia.org/wiki/Presence_information

Clients

GUI clients

  • adium - Mac version of pidgin
  • empathy (comes with Ubuntu) limited usefulness, I uninstalled it
  • pidgin - works well, this and adium are the ones I use. http://pidgin.im
  • psi - has more debugging modes. http://psi-im.org/

Command line

The sendxmpp command line client can be install on Linux systems. It's on dart. 

date | sendxmpp -u [email protected] -p PASSWORDHERE --jserver kilchis.alseageo.com [email protected]

If you create a file .sendxmpprc file you can put a single line in it with a username and password for example 

cat > .sendxmpprc
[email protected] mypassword

then the send line becomes as simple as 

echo "hi brian" | sendxmpp [email protected]

Android

Control your phone via XMPP: http://code.google.com/p/gtalksms/ GtalkSMS is built with: https://github.com/Flowdalic/asmack Looks like it watches services on the phone and sends XMPP messages so for example it will gate SMS to XMPP, the opposite of what I want.

There are about 50 apps in the "store" when I ask for XMPP; these came up at the top today.

  • astrachat
  • pix-art messenger
  • xabber *ad-free! free!
  • xmpp messenger

I vaguely remember xabber and it says it's installed. That means it was installed on some phone I had a few years ago.


Python

Following along in the O'Reilly book I will build a simple client using Sleek. Python XMPP Client

Working with .Net

See Jabber.net

Building pidgin

..because I am interested in libpurple for Windows (and pidgin runs on Windows)

Downloaded and unpacked source from pidgin site.

It is easy on Ubuntu 12.04, once you install the build dependencies. 

apt-get build-dep pidgin
cd pidgin
./configure 
make
sudo make install


Servers

I am setting up a Docker container on Bellman to run Openfire which (a few years ago anyway) I found to be the best option.

These instructions for setting up a Docker version are excellent: https://hub.docker.com/r/gizmotronic/openfire

My command is 

docker run --name openfire -d --restart=always \
 --publish 9090:9090 --publish 5222:5222 --publish 7777:7777 \
 --volume /home/docker/volumes/openfire_xmpp:/var/lib/openfire \
 gizmotronic/openfire:4.2.3

To access the log file, 

docker exec -it openfire tail -f /var/log/openfire/info.log

Shell access, 

docker exec -it openfire bash

XMPP and your firewall

Open port 5222 to allow normal messages to pass between client and server. If you have SSL installed use port 5223. If you want server to server communications then open port 5269.

Openfire

Openfire http://www.igniterealtime.org/projects/openfire/ - my notes from last attempt said "pubsub not working" 3.8.1 says they have fixed pubsub so I am trying again

Installed from packages downloaded from http://www.igniterealtime.org/downloads/index.jsp#openfire (Wget does not work!) On CentOS the package is configured via /etc/sysconfig/openfire.

The web interface seems reasonable. Supports groups.

Shows active sessions.

Has chat rooms. I think this could be a way to send dispatches to a group of users. I can also use the 'broadcast' plugin.

brian/wildsong bwilson/alseageo iv/iv saint/thebells

PostgreSQL

With 3.8.2 set up on Dart with PostgreSQL was easy.

http://10.1.10.70:9090/setup/index.jsp

Plugins

You can install plugins directly from the web interface.

I installed the Asterisk plugin.

I installed the Broadcast plugin. "The broadcast plugin broadcasts messages to all users in the system or to specific groups. It's primarily useful for sending announcements or notifications."

To send a broadcast message, send a message to all@[serviceName].[serverName] or [group]@[serviceName].[serverName]. For example, if your server is called foo and the default service name is being used, a message to [email protected] would be broadcast to all users connected to the server. For the group staff, a message to [email protected] would be sent to all users in the group staff that are currently online or offline.

Prosody

Prosody - my notes say use this one, but trying out Openfire because of the plugins.

Location

There are two docs to look at: xep-0080 to report where client is located and xep-0255 to ask about the location of an entity.

All about XEP-0080

What is XEP-0080 good for?

  • Supports GPS related attributes (aka xml elements) you expect including {timestamp, lat, lon, alt, speed, bearing, datum}
  • Also has elements for everything you might want (floor, street, country, postalcode etc etc)

XEP-0080 message format could easily support E911 dispatch. It includes 'description', 'url' and a catch-all 'text' element.

Container (what XMPP message should carry the location data?):

  • Location of people should be sent via PubSub or PEP(personal eventing).
  • Tracking non-human users (eg a fire truck) can use other containers.

Musts:

  • Lat / lon are signed decimal degrees
  • Altitude units are metric
