My connect call doesn't complete, and when I hit ctrl-c, I get the below message. Any recommendations on how I can further debug this? Thanks!

require 'blather/client'

Blather::Stream::Parser.debug = true

puts 'setup'
setup 'admin@localhost', 'password'

puts 'connecting...'
client.connect
puts 'done'

when_ready {
  write_to_stream Blather::Stanza::Message.new 'user@localhost', 'test msg'
}
$ r test.rb
setup:

So, if you check out the example of a similar case, you don't need to call #connect at all since it's implicit, and certainly doing a blocking connect before setting up handlers is a bad idea. Let me know if you have any issues copying the example.

Thanks, I got it working, but then when I tried to switch to Facebook chat from my local ejabber server, it disconnects as soon as I send a message, and I don't see the message on the Facebook website. I'm using the same username and to: name that works successfully in iMessage. Any recommendations? For instance how to get the reason why the connection was closed?

require 'blather/client'

setup 'me@chat.facebook.com', 'app-specific password'

msg = Blather::Stanza::Message.new 'user@chat.facebook.com', 'test 1'

when_ready {
  puts 'ready'
  write_to_stream msg
  puts 'wrote'
}

disconnected {
  puts 'disconnected'
}

Gives

$ r test.rb
ready
wrote
disconnected

I'm pretty sure it's authenticating correctly, since when I make up a different password, the when_ready block isn't executed, and it disconnects.

Try running with -D to see log output. Also, I was under the
impression that Facebook required a different auth mechanism.

There are two Facebook chat XMPP auth methods. One is your username and an application-specific password, and the other is the app ID and app secret. Unless something jumps out at you from the below, I think I've hit a dead-end with the former and will try the latter next.

$ ruby -d test.rb
...
ready
<message to="[friend]@chat.facebook.com" type="chat">
  <body>test 1</body>
  <active xmlns="http://jabber.org/protocol/chatstates"/>
</message>
