8) Logging on to a strange computer (Using Telnet /Win95 For AOL Connection)

















                 Logging on to a strange computer (Using Telnet /Win95 For AOL Connection).




To do this (I mean to log on to a strange computer, not scare your neighbors) go to the DOS prompt C:\WINDOWS> and give the command telnet. This brings up a telnet screen. Click on Connect, then click Remote System.

This brings up a box that asks you for Host Name. Type whois.internic.net into this box. Below that it asks for Port and has the default value of telnet. Leave in telnet for the port selection. Below that is a box for TermType. I recommend picking VT100 because, well, just because I like it best.

The first thing you can do to frighten your neighbors and impress your friends is a whois. Click on Connect and you will soon get a prompt that looks like this:

[vt100]InterNIC>

Then ask your friend or neighbor his or her email address. Then at this InterNIC prompt, type in the last two parts of your friends email address. For example, if the address is luser@aol.com, type in aol.com.

Now Im picking AOL for this lesson because it is really hard to hack. Almost any other on-line service will be easier.

For AOL we get the answer:

[vt100] InterNIC > whois aol.com

DNS-AOL.ANS.NET 198.83.210.28

These last three lines give the names of some computers that work for America Online (AOL). If we want to hack AOL, these are a good place to start.

Evil genius tip: Using your Win 95 and an Internet connection, you can run a whois query from many other computers, as well. Telnet to your target computers port 43 and if it lets you get on it, give your query. Example: telnet to nic.ddn.mil, port 43. Once connected type whois DNS-01.AOL.COM, or whatever name you want to check out. However, this only works on computers that are running the whois service on port 43. Warning: show this trick to your neighbors and they will really be terrified. They just saw you accessing a US military computer! But its OK, nic.ddn.mil is open to the public on many of its ports. Check out its Web site www.nic.ddn.mil and its ftp site, too -- they are a mother lode of information that is good for hacking.

Next I tried a little port surfing on DNS-01.AOL.COM but couldnt find any ports open. So its a safe bet this computer is behind the AOL firewall.

**********************************
Newbie note: port surfing means to attempt to access a computer through several different ports. A port is any way you get information into or out of a computer. For example, port 23 is the one you usually use to log into ashell account. Port 25 is used to send email. Port 80 is for the Web. There are thousands of designated ports, but any particular computer may be running only three or four ports. On your home computer your ports include the monitor, keyboard, and modem.
