Unable to telnet into Linux box

Can you verify that port 23 is open on the Linux machine?

netstat -tln

If not then enable telnet in xinetd:

chkconfig telnet on

1. Unable to telnet a Linux Box from a Windows 2000 Server

Hi guys!

I just setup a new Red HAt Linux 7.1 box at home and I created a small
network with a crossover cable to my Windows 2000 box. I have assigned
a private address to my Linux box, and  for
my Win box.

I was able to ping both these machines, I was able to telnet my Win
machine but for whatever reason I cannot telnet the linux machine on
any port. I can telent the Linux machine from the linux terminal so
the telnet process is actually working. I know telnet is listening,
httpd is listening and some other port like 22 is open. I even scanned
the linux box and I saw the ports open.
I've tried PUTTY as well, didn't work. When using telnet from Windows,
the message returned was: Connecting to  Could not
open a connection to host on port 23.. Connect failed.

The Windows box is connected to the inernet and has 2 NICs. No routing
service is working.
In short, the only communication between the two boxes is ping at this

Thanks for reading,
hopefully you can give me a hint..
