Explanation:
The following describes the correct configuration guidelines for setting up telnet access to a router:
Background Information
If you try to telnet to a router that does not have a Telnet password configured, you will get the
following error message: Router-1# telnet 10.3.3.1 Trying 10.3.3.1 … Open Password required,
but none set [Connection to 10.3.3.1 closed by foreign host]
Configure
In this section, you are presented with the information to configure a Telnet password.Configurations
This document uses this configuration:
* Router-2
In order to set up the router to allow Telnet access, use the line vty command. This command
allows for the configuration of Virtual Terminal (VTY) lines for remote console access. You can
configure the router to accept one or more Telnet sessions. It is strongly suggested that you
configure password checking with the login and password line configuration commands. The
example below configures the router to accept five sessions, with the password “letmein”:
Verify
To verify that the router is correctly configured for Telnet, issue the show running-config command.
Router-2# show running-config Building configuration… hostname Router-2 . . line vty 0 4
password letmein login . . ! end
You should now be able to telnet to the router. Router-1# telnet 10.3.3.1 Trying 10.3.3.1 … Open
User Access Verification Password: letmein Router-2#
