  • Page 27: Chapter 4 Configuring Ports

    These are described in the following sections. Console Server Mode Configuring a serial port as a console server creates a TCP socket on the Digi CM that listens for a Telnet or SSH client connection. Users who connect to the TCP socket have access to the device attached to the serial port as though the device were connected directly to the network.
  • Page 28 In terminal server mode, the Digi CM serial port is configured to wait for data from the device connected to the port. If data is detected, the Digi CM starts a TCP session as a Telnet or SSH client to a pre-defined server. The server must be defined by the user before the port can be configured for a Telnet or SSH client.

  • Page 29: Configuring Host Mode

    When users dial-in using terminal applications, the Digi CM accepts the connection as a Telnet or SSH client to a pre-defined server. This mode is most frequently used when users want to use modems to access servers on a network.

  • Page 49: Introduction

    Chapter 7 Introduction The Digi CM provides several ways to control access to the network and the devices on the network. One method is through IP filtering, which allows or prevents users with specific IP addresses from accessing devices or serial ports on the network.
  • Page 50 Configuring Network IP Filtering Console and Web IP Filtering IP filtering is a way of controlling access to the Digi CM from remote hosts. If the administrator wants to allow specific remote hosts access to the Digi CM, the administrator must provide the host’s IP address and subnet mask. To configure the Digi CM for IP filtering, do the following: 1.

  • Page 51: Using Ip Tables

    Configuring User Access Control MIKE Another method to control access to the serial ports on the Digi CM is through the User Access Control configuration. This configuration can be done on a per port basis or globally by selecting the All Ports option. There are three options for user access control: None, Restricted user list, and Permitted user list.
  • Page 52 A sniff session enables multiple users to access a single serial port for viewing the data stream. Users who are registered for a sniff session can access a specific serial port even if another user is using the port. The Digi CM supports multiple concurrent sniff sessions.
  • Page 53 Viewing A Sniff Session A sniff user enters a sniff session by starting a Telnet session on a specified port. In the following example, a sniff user Telnets to port 7 of a Digi CM. From the command prompt enter the following command: telnet 192.168.100.42 7007...

  • Page 54: Authentication

    • 6 (Quit): Closes the Telnet session. Authentication The Digi CM supports multiple methods of user authentication. The following methods are supported: Local, TACACS+, RADIUS, LDAP, and Kerberos. The type of authentication protocol you use is dependent on your environment.

  • Page 62 Making Custom Menus Assigning Users To A Menu Once a menu has been created, users can be assigned to the menu by doing the following: 1. Access the web interface. 2. Under the Custom Menus heading, choose Configuration > Menu Users. A list of available users is displayed.

  • Page 63: Using The Configuration Menu

    The configuration menu is available through a Telnet or SSH session to the root user and system administrator. The configuration menu enables the authorized users to configure the Digi CM with the same functionality as is available with the web interface. The only functionality missing from the configuration menu is the ability to create custom menus.

  • Page 64: Port Access Menu

    Users access this menu through a Telnet or SSH session using the IP address of the Digi CM followed by the port number 7000. Here is an example: telnet 192.168.100.200 7000 By default root is connected to the command line interface and the preceding option allows the root user access to the port access menu.

  • Page 65: Chapter 9 Configuring Remote Dial-In Access

    Digi CM accepts the connection and displays a menu of available serials ports. In a dial-in terminal server mode, the Digi CM makes a TCP connection with either a Telnet or SSH client to a pre-defined server. RawTCP is also an option for dial-in users.
