Telnet in RHEL 5 on the opening process

1, make sure your telnet service is not open:

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

ekrb5-telnet: off

krb5-telnet: off

[Root @ 111 ~] #

Note here that off test results

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 ~] #

Inspection has been opened

3, modify the login files securetty, a major increase to the terminal point of landing

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

Add the following lines:

pts / 1

pts / 2

pts / 3

pts / 4

pts / 5

... ...

Save eject.

If chkconfig krb5-telnet on

Prompts Unencrypted connection refused. Goodbye.Connection closed by foreign host. See the error message seems to be saying for the encrypted connection is rejected, view his profile did not find any on the encryption option, and the configuration file is also correct, then go to google search a large circle, and finally find a foreigner to write a solution:

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.

Original ekrb5-telnet is a need to encrypt the telnet service to start on the course, this service requires encryption. Solutions: / etc/xinetd.d/ekrb5-telnet inside disable change = yes, then restart the xinetd service xinetd restart service to OK it!
