Accessing Attached Devices

Chapter 14 Configuring Console Management 68

Example: SSH2 and Menu Access

In this example, a Digi device is configured to use an SSH2 public key, and it presents a menu to the

administrator, from which he or she will select a device to manage.

Key aspects of this configuration include the following:

• Two ports to which the managed devices are connected specify dev=prn, a device type that does not spawn a

• A menu specifies connect commands, which when selected provide connections to ports 1 and 2 and the man-

aged systems. The menu also specifies a menu table index number of 6 (on the range parameter), which is

then linked to a user with the set user command

set ports dev=prn range=1-2

set line baud=19200 range=1-2

set menu name=menu1 t1="Console Management Menu" range=6

set menu name=menu1 range=6 m1="Connect to System 1" c1="connect 1"

set menu name=menu1 range=6 m2="Connect to System 2" c2="connect 2"

set user name=admin1 defaultaccess=menu menu=6 password=on outgoing=on

set user name=admin1 loadkey=142.191.2.34:ssh-file1

newpass name=admin1

Accessing Attached Devices

Telnet

Telnet is a direct connection to another device on the network. Once a user is connected to the device with a

telnet session, they can connect to a specific port. Use the following procedure to initiate a telnet session:

telnet ipaddress

An example is: telnet 192.168.5.24

At the command prompt, the user can connect directly to a port by entering the following command:

connect portnumber

An example is: connect 4

This command initiates a telnet session on port 4. Other methods for accessing ports using a telnet session are

through Custom Menus and Autoconnect.

Telnet Direct to a Port (Reverse Telnet)

Where Telnet is a direct connection to a device, reverse telnet is a direct connection to a device’s serial port from

the network. In the example below, a user connects directly to serial port 4 on a PortServer. Reverse telnet uses a

socket numbering scheme starting with 2000 plus the port number.

telnet 192.1.2.3 2004

A reverse telnet session can be authenticated on a Digi device with a RADIUS server.

Note: Ports must be configured for console management before they can be used for reverse telnet or reverse ssh.

See "Configuring a Port for Autoconnection: Web Interface" on page 48.
