1. Make sure your telnet service is open:

[root@111 ~] # chkconfig-- list | grep telnet

Ekrb5-telnet: off

Krb5-telnet: off

[root@111 ~] #

Pay attention to the results of the check. this is closed.

2. Open the telnet service:

[root@111 ~] # chkconfig krb5-telnet on

[root@111 ~] # chkconfig-- list | grep telnet

Ekrb5-telnet: offv

Krb5-telnet: on

[root@111 ~] #

The check has been opened.

3. Modify the login file securetty, mainly adding the terminal to be logged in.

[root@111 ~] # vi / etc/securetty

Add the following lines:

Pts/1

Pts/2

Pts/3

Pts/4

Pts/5

……

Just save and exit.

If it's chkconfig krb5-telnet on,

Will prompt Unencrypted connection refused. Goodbye.Connection closed by foreign host. Looking at the error message, it seems that the encrypted connection was rejected. I checked his configuration file and found no options for encryption, and the configuration file was very correct, so I searched google and finally found a solution written by a foreigner:

I really needed a bit of guidance and you provided it./sbin/chkconfig-- list | grep telnetThe above command told me I had both krb5-telnet and ekrb5-telnet, andalso the installed telnet all on. Initially I did not know what theywere all for. After turning them on and off and testing my telnetconnection from another box I realised that "ekrb5-telnet" was theencrypted telnet server that I needed to turn off to run "krb-telnet" which allowed non-encrypted telnet connections.eg / sbin/chkconfig ekrb5-telnet offThanks for your help.

It turns out that ekrb5-telnet is a telnet service that needs to be encrypted. Of course, encryption is needed to start this service. Solution: change the disable in / etc/xinetd.d/ekrb5-telnet to = yes, and then restart the xinetd service service xinetd restart to OK!
