4. Use the device to log in to a

Telnet server.

• Log in to an IPv4 Telnet server:

telnet remote-host

[ service-port ] [ [ vpn-instance

vpn-instance-name ] | [ source

{ interface interface-type

interface-number | ip

ip-address } ] ]

• Log in to an IPv6 Telnet server:

telnet ipv6 remote-host [ -i

Use either command.

Logging in through SSH

Introduction

SSH offers a secure approach to remote login. By providing encryption and strong authentication, it

protects devices against attacks such as IP spoofing and plain text password interception. You can use an

SSH client to log in to the device working as an SSH server for remote management, as shown in Figure

22. Y

ou can also use the device as an SSH client to log in to an SSH server.

Figure 22 SSH login diagram

Table 6 shows the SSH server and client configuration required for a successful SSH login.

SSH server

Configure the IP address of the device's management interface, and make

sure the SSH server and client can reach each other.

By default, the IP address of the management interface is 192.168.0.1/24.

Configure the authentication mode and other settings.

SSH client

If the host operates as an SSH client, run the SSH client program on the host.

Obtain the management interface's IP address of the device to be logged in .

To control SSH access to the device working as an SSH server, configure authentication and user

privilege level for SSH users. By default, password authentication is adopted for SSH login, but no login

password is configured. To allow SSH access to the device after you enable the SSH server, you must

configure a password.
