Is your friend invisible on Yahoo!

August 10th, 2004 by sameer | Posted in Technical, Tutorials, Tips & Tricks |

We now know how to find out the IP address of our online friends on Yahoo!. To find out if a friend is actually hiding in Invisible mode:

  1. Connect to the Internet
  2. Sign into Yahoo! Messenger
  3. Send a chat message to any ‘yahoo id’ you want to check for online status
  4. Open your command prompt. (type “cmd” or “command” in the ‘Run’ box from ‘Start->Run’
  5. Type netstat
  6. In the column Local address, look for port 5101.
    e.g.
    TCP HOME:2729 testsever.sameerhalai.com:47572 TIME_WAIT
    TCP HOME:2730 testsever.sameerhalai.com:52239 TIME_WAIT
    TCP HOME:2732 testsever.sameerhalai.com:2899 TIME_WAIT
    TCP HOME:2733 testsever.sameerhalai.com:30837 ESTABLISHED
    TCP HOME:5101 203.115.xx.xxx:4990 ESTABLISHED

If you do not find any entry for port 5101, then your friend is indeed offline. But in case you find an entry for that port, then the corresponding Remote Address is the IP address of your friend who is Hiding in Invisible Mode.
