Hi, I think you mean Red Hat Linux. Any, FYI telnet is turn off by default. If you want to login into the box,use ssh.

I think u r loging in as root , which is by default blocked except from console . to enable login as root from ur telnet client u have to rename the /etc/securetty file as something like /etc/securetty.old or u need to login as a normal user and su to root from the telnet client.

Hi Binu ,

If you are getting the logon screen , that means , telnet service is enabled and running on the server.

The password is not accepting means , some problem. Well, If you are trying to logon as root , it will not allow you as only allow on console.

So you need to edit the file to put entry ..

1.# vi /etc/securetty and add pts/0 pts/1 (these are tty name from which u will be loggin in).
2.# vi /etc/xinetd.d (and at telnet entry put , disable=no)

Hope this will help you ,

Cheers ,
RajD.

The problem is most likely that you are logging in as root and there is no tty device entry added in /etc/securetty file.

As suggested add pts/0, pts/1 and more in /etc/securetty file and try logging in. Another checkpoint to be visited is the PAM security system, ensure there is no misconfiguration in PAM setup

Hi,

Are you facing telnet problem for any particular user or root. If only for root user, then under /etc move the file securetty to securetty. and try.

Rajesh
