Logging In Through Ssh - HP 830 Series Configuration Manual

Step
2. Specify the source IPv4
address or source
interface for outgoing
Telnet packets.
3. Exit to user view.
4. Use the device to log in
to a Telnet server.

Logging in through SSH

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 operating as an SSH server for remote management, as shown in
13. You can also use the device as an SSH client to log in to an SSH server.
Figure 13 SSH login diagram
Table 16 shows the SSH server and client configuration required for a successful SSH login.

SSH client
To control SSH access to the device operating 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.
Command
telnet client source { interface
interface-type interface-number | ip
ip-address }
quit
•
Log in to an IPv4 Telnet server:
telnet remote-host [ service-port ]
[ source { interface interface-type
interface-number | ip ip-address } ]
•
Log in to an IPv6 Telnet server:
telnet ipv6 remote-host [ -i
interface-type interface-number ]
[ port-number ]
Requirements
Assign an IP address to a Layer 3 interface, and make sure the interface and
the client can reach each other.
Configure the authentication mode and other settings.
If a host operates as an SSH client, run the SSH client program on the host.
Obtain the IP address of the Layer 3 interface on the server.

Remarks
Optional.
By default, no source IPv4 address
or source interface is specified.
The device automatically selects a
source IPv4 address.
N/A
Use either command.
