---------- Forwarded message ----------
From: Tha.Suresh

Ever wanted to know that someone is really offline or has just gone
invisible in GTalk? Here is a small trick. The bellow peace of python
code get the list of invisible users from your GTalk buddy list. It
uses XMPP module for python. You can install this module in
Ubuntu/Debian via apt. It also requires python dns module.

sudo aptitude install python-xmpp python-dnspython

Now here is our script. Open your favorite text editor and save the
code as ‘gchat.py’. Dont forget to fill your gtalk username and
password in the script.

#gtalk.py

import xmpp

# Google Talk constants
FROM_GMAIL_ID = "username@gmail.com"
GMAIL_PASS = "secret passwd"
GTALK_SERVER = "gmail.com"

jid=xmpp.protocol.JID(FROM_GMAIL_ID)
C=xmpp.Client(jid.getDomain(),debug=[])

if not C.connect((GTALK_SERVER,5222)):
   raise IOError('Can not connect to server.')
if not C.auth(jid.getNode(),GMAIL_PASS):
   raise IOError('Can not auth with server.')

C.sendInitPresence(requestRoster=1)

def myPresenceHandler(con, event):
  if event.getType() == 'unavailable':
    print event.getFrom().getStripped()

C.RegisterHandler('presence', myPresenceHandler)
while C.Process(1):
 pass

$ python gchat.py
So , Next time do not let anyone fool you , rather catch him Invisibly.   ;-)
