unable to login using telnet

manoj.linux · 11-09-2010, 11:03 AM

Hi,

I am using redhat linux 4.0, I have started the telnet services, and getting login prompt after entering correct username and password getting the error .

login: Resource temporarily unavailable while getting initial credentials
Login incorrect

my login details are correct.

even I have tried on that linux box

telnet localhost 23 in that case also I am not able to login.

service iptables is stopped, no security is configured.

Have you looked at the telnet configuration file? It should be somewhere in the /etc directory I would think. I haven't used telnet in a long time since SSH is more secure.

Is the user able to log in locally on the machine?

Kind regards

Thanks for response, user is able to login via putty (22), but my requirement is temporary,

I have done the below steps

vi /etc/xinetd.d/krb5-telnet
disabled=no

pkill -HUP xinetd.

I am getting the login prompt for adding username and password.

is any other configuration file needs to be configured for user.

Regards

Manoj

Hi,

Please confirm you have telnet-server rpm installed using:

Code:

rpm -qa | grep -i "telnet-server"

If you are connecting from a remote computer, it's possible the characters aren't transmitted correctly.
Try to connect locally and see if the problem persist, or use another client to connect.

Kind regards

You are connecting as a user, not as root, right?

Kind regards

The error indicates that your system is using kerberos, or that telnet is trying to use it.

Modify the /etc/xinetd.d/eklogin file, and set the disable option to yes, then restart xinetd. Also, since you're using RHEL, you can call RedHat for support, since you're paying for it.
