[14:23] *** Creating connection "alaricd at gmail.com/Trillian"
[14:23] *** Server supports TLS encryption...
[14:23] *** Negotiating XMPP SSL connection...
[14:23] *** Connection established using EDH-RSA-DES-CBC3-SHA (TLSv1/SSLv3)
[14:24] *** Attempting to authenticate using PLAIN
[14:24] *** Authenticated.
