5.1.2 User Management
The username and the password are not configured when a router is powered on for the first
time.
In such a condition, any user can configure the router by connecting a PC with it through the
console port.
The remote user accesses the router through Telnet if the router is configured with the IP
address of the Routing Process Unit
(
RPU) or that of the interface board. The remote user
accesses the network by establishing a PPP connection with the router.
Configure the usernames and the user password for the router to ensure network security and
to ease user management.
User Classification
Based on the services obtained, users of a router are classified as follows:
z
HyperTerminal users
: They access the router through the console port or the AUX port.
z
Telnet users
: They access the router through Telnet.
z
File Transfer Protocol (FTP) users
: They establish FTP connections with the router to
transfer files.
z
Point-to-Point Protocol (PPP) users
: They establish PPP connections (such as dialing
and PPPoA) with the router to access the network.
z
Secure Shell (SSH) users
: They establish SSH connections with the router to access the
network.
