During this learning phase i came across a strange problem.

I was just checking the configuration file of /etc/xinetd.d/krb5-telnet and i thought of enabling the telnet.
I modified the configuration file accordingly and restarted the server.
Code:
# cat /etc/xinetd.d/krb5-telnet
# default: off
# description: The kerberized telnet server accepts normal telnet sessions, \
# but can also use Kerberos 5 authentication.
service telnet
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/kerberos/sbin/telnetd
log_on_failure += USERID
disable = no
}

Now i can able to telnet to the server from any other machine But the problem is it is not allowing me to login with correct root credentials.

What could be the issue here?

I m able to login with ssh protocol.

RXTELNET(1)						    BSD General Commands Manual 					       RXTELNET(1)

NAME
rxtelnet -- start a telnet and forward X-connections. SYNOPSIS
rxtelnet [-l username] [-k] [-t telnet_args] [-x xterm_args] [-K kx_args] [-w term_emulator] [-b telnet_program] [-n] [-v] host [port] DESCRIPTION
The rxtelnet program starts an xterm window with a telnet to host host. From this window you will also be able to run X clients that will be able to connect securely to your X server. If port is given, that port will be used instead of the default. If setting up the X forwarding failes, rxtelnet will still telnet in to the remote host, but without X forwarding. The supported options are: -l Log in on the remote host as user username. -k Disables keep-alives. -t Send telnet_args as arguments to telnet. -x Send xterm_args as arguments to xterm. -X Send kx_args as arguments to kx. -w Use term_emulator instead of xterm. -b Use telnet_program instead of telnet. -n Do not start any terminal emulator. -v Be verbose. EXAMPLE
To login from host foo (where your display is) to host bar, you might do the following. 1. On foo: rxtelnet bar 2. You will get a new window with a telnet to bar. In this window you will be able to start X clients. SEE ALSO
