Hi OK.....lotta friends of mine asking this question too! So here it is..... The people who already know such stuff can ignore this and stop using word as LOL/OLD news. Technique A 1. GAIM is the software that lets u have the IP of the person directly chatting. 2. All u need to do is inititiate a chat with the person. 3. After that press on the info button in the corresponding chatting window. 4. There u go....u have the direct IP of the computer and no yahoo proxy. 5. Neways it rarely doesnt show the IP. Technique B 1. Tell ur friend to email anything(Joke or whateva) to u 2. When u recieve the mail look for email headers 3. There are two "From" fields 4. One field tells u the IP of smtp server of the email engine used and the other tells u the IP of ur friend. Technique B wont work if ur friend has used some proxy. But yahoo doesnt allow a proxy to be used! So in case ur friend has used yahoo, then u have a good success rate. There are some more techniques I know. But that requires programming! If ur interested in programming....then tell! I can tell u about the idea. Finding out the IP is no big deal. But then creating terror for that IP is unethical and certainly not good for u. You kow what i mean. You wont get anywhere if the IP u found is of some router coz most routers dont allow telnet/ftp/ssh from external network for security purpose by default. Most home users dont enable any exploitable services like telnet. So u wont achieve anything by finding IP. This is just the basics. This is not considered cracking or hacking(as most of u call it). But then using the evil in ur mind after this can certainly land u up in jail.
