What is telnet ?
While being one of the most unsecure protocols, due to it’s transfer of passwords in cleatext, this is one of the most useful and widely used protocols/applications.
How can you connect to a router using Telnet ?
First you need to configure the router to accept telnet logins by doing
line vty 0 4
password cisco
login
This will enable 5 simultaneous telnet logins to the router.
on smaller routers, configuration is accessed by connecting through a web browser. So telnet is not an option.
