Google Talk over XMPP

Question

I am trying to establish a XMPP connection to talk.google.com on port 5222, however I am getting a 301 MOVED PERMANENTLY response redirecting me to hangouts.google.com.

I know Google abandoned GTalk, and what I could find is really inconclusive of whether the service is actually still up and running (although not maintained), or not.

I almost gave up thinking it is just not there anymore, however last try using external client (Adium...like Pidgin but for Mac) instead of my own library (XMPP-PHP), ended up actually connecting to the server and sending messages all fine.

Is there something I'm missing?

Answer 1

I have found the right URL to be talk.l.google.com.

Answer 2

You want to do an DNS SRV record lookup to find the actual server to connect to, eg https://kingant.net/check_xmpp_dns/?h=gmail.com says that the client records for gmail.com's XMPP server are xmpp.l.google.com and alt{1..4}.xmpp.l.google.com

Alternatively, you could use a hangups-based solution to speak the native Hangouts protobuf format: https://github.com/tdryer/hangups/
