Can telnet port 80 but cannot ping!

[taalebi at ai.mit.edu (Ali Taalebi)]

Thanks for your response.
Seeing that telnet to port 80 works, I wrongly assumed that telnet is 
running on my server. But you guessed it right, it does't!

When I type:
	locate telnetd
I just find /usr/sbin/in.telnetd and something in ../man/..
which apparently means RedHat has not installed telnet for me.
I will appreciate if at your convenience you can let me know 
what module I need to instal? 

I recall that I picked whatever firewall services RedHat was offering 
when I was installing it. I also have a LinkSys Router which has some kind of
fire wall. Whould I need to disable both RedHat and LinkSys Firewalls 
in order to have ping service?

Thanks again.
>>Ali

   Are you running a telnetd?
   Do you have ICMP messages blocked via some firewall?
