On a mac, install with brew!

brew install node

Run:

curl https://npmjs.org/install.sh | sh

On a mac, install with brew!

brew install icu4c
brew link icu4c

Install via:

npm install -g simple-xmpp

Once you've installed all the requirments, you will need to configure your bot.

cp config-example.js config.js
vi config.js

Note: you'll need to create a jabber account somewhere so this will all work. If you don't have your own domain name, using Gmail is always an option. Once you've created your bot's account, you'll need to log in as your bot via a chat client and invite your primary account as a friend.

Obviously, replace SOME.IP.ADD.RESS with the IP address that you expect to receive UDP packets from.

Run this bad boy like so:

node bot.js

If you plan on accepting UDP traffic from a host other than your local host, you'll probably need to punch a hole in your firewall.

Check to see what you have in ipfw:

sudo ipfw list

Choose a sequence number for your firewall rule (this example uses the number 10):

sudo ipfw add 10 allow udp from SOME.IP.ADD.RESS to any 8888

If you, like me, want to have this bad boy running any time you need it, you can set it up as a process using forever, a handy npm. To get it, run:

sudo npm install -g forever

Then, to forever run the bot, simply:

cd /path/to/jabberbot
forever bot.js
