I.P. Addresses, Please Read If Computer Whiz..

Sat Dec 22, 2001 4:32 pm

Ok, my friend kept boasting today in class that he could find my i.p. address without even getting on my computer. Now, for those who know what I'm talking about so far, he did find my I.P. address from his own computer. So, I had to restart mine because of an unrelated reason, and I chacked my I.P. address again, and it appears that my I.P. address is a rolling I.P., meaning I have no set location on the web. So, I told him to try and get my new IP, and he got it. He wouldn't tell me how because it's a secret, but he said it's something in the "Ports Recents," where he somehow found what port I had connected to and got my IP address from there. Now, how did he do this? I would like to know so I could get back at him. He said that by my accepting an AIM Instant Message, I gave him free oppurtunity to find my port and my IP, so some of you computer whizzes out there, please tell me how he did this...

Dunno about the IM method, but you can simply run 'finger abc@xyz.com' in UNIX/Linux to get abc's dynamically assigned IP host, and then do a 'ping ' and get the actual IP address.

AOLIM is most likely a Client-To-Client communication (CTCP) so you can get his IP by monitoring your network sessions. Open up a command prompt and type "netstat". If that isn't sufficient, try "netstat -A"

I'm sure there're more efficient ways of finding out what you want to know, but this should work.

Wait, did I just tell you how to become a nuisance on the internet? Well don't be one!

Tell him that being able to find someone's ip means nothing. Anyone worth their salt in networking can find an ip with their eyes closed and both hands tied behind their back (type with the feet, it works Big thumbs up).

AOL IM is not client-to-client generally, however if you initiate a direct connect session (i.e. to send pictures or whatever) then it is a client-to-client method. This would allow him to get your ip by the above netstat method.

If he thinks he's so hot, tell him to find your terminal location number.  Big thumbs up

Having your IP address doesn't mean anything unless anything is done with it...the worst thing that can happen to you is a DOS attack unless they know what they're doing. But I doubt you are a target for such nonsense unless you piss the wrong people off  Smile Johan has your IP address too every time you post a message, in case you were wondering.

Yeah, I don't think it means much to find a person's IP. Tell him if he's really good to figure out somebody's AOL password  Big grin

I rememeber when I had ICQ that the IP address was even written in the user's profile. You had to configurate it if you didn't want your friends to know yours.

He claims that there is a command under dos that if you type in restart or something along that line, and then add the IP of a certain compute, you can restart that person's computer.

Yes, I did initiate the the Direct Connect, on AOL IM. I thought it had something to do with it.

Next time I talk to him through direct connect, should I try that netstat or netstat-A?

I know there is a way to crash a person's computer but I couldn't begin to tell you how to do it. My brother gets into all of that stuff playing Halflife. Somebody will boot him out of a game because he plays so well. Then he'll come back and crash the guy's whole computer. Nerd wars.

There are many ways to attack someones computer if you know their ip. However, I wouldn't do it unless you really hold a grudge. If someone attacks my computer, or even hints, I generally let their ISP know about it and they'll shut them down (usually).

About rebooting someone's computer, you can't do it remotely only by knowing their ip, unless you know of, and have access to, a trojan type program on their computer, or know of a security hole in their OS or some service they're running that would allow you sufficient access to reboot their computer.

With the Halflife deal, as an initial guess, I'd say they're doing some form of a DOS attack to crash the other guy's computer, a ping flood is the easiest, though I wouldn't be suprised if there's some "feature" in Halflife that would allow you to achieve the same result. Make sure he knows that what he's doing is illegal, and if he hit the wrong person, he'd get blasted for it.

Next time you direct connect with him, do a netstat at your command prompt. No need for the -A. You're looking for an ESTABLISHED connection, his ip will be under the foreign address column, it's format is IP:PORT. His port makes no difference, there are literally thousands on everyone's computer, and it'll probably be different every time, don't remember for sure it's been awhile since I've looked at an AOL direct connect. Netstat is going to show all your internet connections, all the ones with port 5190 will be connections to the AOL IM server, and aren't what you want. If you can't figure out which one is his, post the output here and maybe I can figure it out.  Big thumbs up

Ok this is what I just got 10 mins ago from a direct connect with him, his ISP is adelphia.net, if that helps.

To get his IP type:
ping oh-garfield1a-79.clvhoh.adelphia.net

It will tell you that his IP is 24.51.35.79

Thank you for your help, I know one way of finding I.P's now, through AOL IM direct connect, but what other ways are there to find I.P's of people not using AOL IM like regular AOL users, using Windows ME and MS-DOS?
