Management Access

Telnet allows you to connect to the Services Router and access the CLI to execute
commands from a remote system. Telnet connections are not encrypted and therefore
can be intercepted.
Telnet access to the root user is prohibited. You must use more secure methods,
such as SSH, to log in as
If you are using a JUNOScript server to configure and monitor routers, you can activate
clear-text access on the router to allow unencrypted text to be sent directly over a
TCP connection without using any additional protocol (such as SSH, SSL, or Telnet).
Information sent in clear text is not encrypted and therefore can be intercepted. For
more information about the JUNOScript application programming interface (API),
see the JUNOScript API Guide.
