hello ,
I am still not able to get my REDhat Linux box to connect to the internet.
1)I checked up /etc/xinetd.d/telnet . In that the flag disable is set to no. So, i think telnet is up n running. 
try netstat to see if port open
2)When i say ifconfig, I get eth0 and lo as running with my eth0 mask being 255.255.252.0. 
3)>ifup eth0 does not give any error.
4)When I type >route, I get * for gateway in all the rows.
5)When i type >route -n, I get 0.0.0.0 for gatway for all rows.
6)my /etc/hosts file looks like this:
127.0.0.1 localhost.localdomain localhost

What is in /etc/nsswitch.conf? There must be line like "hosts: files dns"
May be there is firewall, which redhat setup by default. What says iptables -L
Please help me out... Help truly appreciated 
Thanks
Suhail.

    Not sure about RedHat. However.

    1) Not being able to telnet to localhost may just mean that telnet
    is turned off. It is in
    Debian by default, if I remember right. Or, you could have firewall
    rules that prevent telnet.
    Try ping localhost and see if that works.

    2) Assuming localhost is up, look at ifconfig. Make sure your
    interface (eth0) is up. If not,
    make sure the the module for your network card is up (lsmod).

    3) Assuming your interface is up, type route to find your gateway.
    Try pinging your gateway.
    If you can get a return from your gateway, your part of the network
    is set up correctly. It is
    an issue with your provider.

    4) Assuming you can successfully ping your gateway, try pinging an
    external system by ip. If
    you can do that, you are likely not resolving. Check
    /etc/resolv.conf and make sure you have
    one or more nameserve rs defined.
