So you will need to run the following commands:. This setting will allow unrestricted access on all ports except port At this point, the Digi unit will prompt for a username and password and will verify both are correct, before allowing access on the port. This can be checked by telneting to the Digi unit, loging in as root, and typing the following commands:.
Look for the tty port. For example, if you are getting the error from a reverse telnet into port 16, look under the TTY column for If you see it, type:. Retype the "who" command. It should not show an entry for the TTY. Then try to reverse telnet into that port again. This allows access to your console ports if the network goes down. Decide which port you want to set a modem up on. Then follow the setup guide for installing a modem.
Simply set up the rest of the ports to provide the reverse telnet capability to each of your console ports as described earlier. In the event of a network failure, simply call the phone number of the modem you have set up on one of our ports. Simply point your web browser to the unit IP address. This would be the most user friendly method for configuring Console Management. The following example will show menu configuration using the command line interface.
By logging in as a specific user other than root you will have a menu. Exiting from the port will bring you back to the menu. For the example below we will create a menu to give us the option of connecting to a Cisco on port 10 or the Sun server on port The menu will be accessed by the user "manager".
Before starting the reverse telnet set-up, first verify that the correct ip address, submask settings are correct. To verify, type set config from the root prompt. The information will display on your screen. Setup your menu. You must use the ''''connect'''' command to gain access to the serial ports. Next we create the user for the menu and specify an escape character. Issuing the escape character along with a carriage return will break your session and bring you back to the menu.
In this example will break your session. Embedded Systems Connect your devices with versatile modules and powerful single-board computers designed for rapid deployment and scalability.

Basic Unit Configuration: Befor configuring the port s , you will need to minimally assign an IP address to the unit. Port Configuration for Reverse Telnet: Reverse Telnet means that instead of initiating a telnet session from the Digi ethernet product into the network, the session will be initiated from the network into one of the Digi serial ports.
Advanced Features and Typical Problems: There are a few common tasks that are requested, beyond the basic setup. Can I assign each port an IP address?
