More on Telnet: the
Number One Hacker Tool
Windows 2000 works pretty much like Unix. See Figure 1 for
an example of a Win 2000 telnet login. Not shown on the screen
was the command "telnet 10.0.0.10", which I gave at
the Command (MS-DOS) prompt.
Figure 1: Telnet using Windows
2000
If you have Windows 95, 98 or NT, to telnet, bring up the
MS-DOS prompt (Start --> Programs --> MS-DOS).
Click "connect" then "remote system…".
In the host name box place the host name or IP address of the
computer to which you wish to telnet. Leave the Port and Term
Type boxes alone for now.
Here is a really important point. Every day people email me
complaining that some computer won't let them telnet into it.
They ask what they are doing wrong. They aren't doing anything
wrong:
- Maybe the computer they are trying to reach no longer exists.
- Maybe the computer they are trying to reach doesn't allow
telnet logins. For example, whois.internic.net no longer allows
telnet logins on port 23 (the default port). Click
here to learn how to telnet into whois.internic.net on the right
port for that particular server.
- Maybe a firewall is blocking them.
- Or maybe they make a telnet connection and the remote computer
asks for a user name and password they don't have. Then they
email me asking for how to get a login name and password that
will work.
Newbie note: The owners or administrators
of any Internet host computer decide who gets user names and
passwords. Believe it or not, about once a week someone emails
me asking what user name and password their own online service
provider has assigned them for a telnet login. That's why I'm
telling people the obvious -- if you want to telnet into any
computer, and you don't have a user name and password, you must
ask the owner, administrator of tech support for that system
for a user name and password. If they won't give that to you,
they don't want you to have it!
You can go to jail warning: If
you guess the user name and password, or use a computer breakin
technique to get or create them, or if someone other than an
owner or administrator or a legitimate user on that system gives
you a user name and password, it is against the law to use them.
Many computer criminals give out user names and passwords that
they obtained illegally.
