Config for Irssi to connect to various XMPP chat servers. Replace the passwords, usernames an ids by your own. Remember, the irssi-xmpp (http://cybione.org/~irssi-xmpp/) plugin is requried.

# irssi-xmpp plugin required

servers = (
  {
    address = "chat.facebook.com";
    chatnet = "facebook";
    password = "<password>";
    autoconnect = "true";
  },
  {
    address = "talk.google.com";
    chatnet = "gtalk";
    password = "<password>";
    #autoconnect = "true";
  },
  {
    address = "chat.hipchat.com";
    chatnet = "hipchat";
    password = "<password>";
    autoconnect = "true";
  }
);

chatnets = {
  gtalk = { type = "XMPP"; nick = "<email address>"; };
  # https://www.facebook.com/settings?ref=mb
  facebook = { type = "XMPP"; nick = "<facebook user name>"; };
  # https://regrates.hipchat.com/account/xmpp
  hipchat = {
    type = "XMPP";
    nick = "<Jabber id>";
  };
};

channels = (
  # Join Mutli-User Chat (MUC) automatically.
  # 
  # In order to join a group conversation you have to use your HipChat nick name.
  # You can do this automatically by setting 'set alternate_nick You HipChat Name' in a file
  # 'startup' in the irssi folder.
  { name = "<Jabber id of group>@conf.hipchat.com"; chatnet = "hipchat"; autojoin = "Yes"; }
  { name = "<Jabber id of group>@conf.hipchat.com"; chatnet = "hipchat"; autojoin = "Yes"; }
);

Does this still work? I thought Facebook and Hangouts are not supported for about a year now and this config file has 5 months?
