Well,looks like you have a running firewall.
try: service iptables stop
and then check again. It's preferably to use ssh nowadays....

[Bill Thorsteinson]

Check netstat -lnt to verify that something
is listening to telnet.
Check hosts.allow and hosts.deny to ensure
telnet is not disabled there.
Check iptables -L to ensure that
telnet is not disabled there.

Or more secure reset the disable parameter
to YES and use SSH.

I have stoped the iptables service , Now i can able to open telnet session , but i cannt able to login as a root in telnet session.Where can i change the console login as a root anywhere.

to be able to login as root via telnet
you must append to /etc/securetty
pts/0
pts/1
pts/2
pts/3
....
pts/20

and then again restart the xinetd service

Shalom,

by default telnet is disabled for root on Linux systems. Then again, so is telnet, so someone has modified the system already.

For root access, you may need to log in with ssh, assuming you have the root password.

Otherwise you need to boot with a rescue cd get a prompt and type the command passwd root
