Command Line Interface
Chapter 15
Introduction
C o m m a n d L i n e I n t e r f a c e
The Digi CM runs the embedded Hard Hat Linux operating system. The command line interface for configuration purposes is accessible only by the root user. The system administrator has read only privileges from the command line. By default the root user is connected to the CLI (command line interface) when accessing the Digi CM through Telnet or SSH. To gain access to the command prompt, the root user uses the username root and the root password. The default root password is dbps.
This chapter includes the Linux commands available on the embedded Linux operating system and the location of files useful to the root user for administrative purposes.
Note: The root user should be aware that deleting or corrupting files may prevent the Digi CM from booting properly. Before editing any files, be sure to back up your configuration files.
Linux Commands
The purpose of this section is to list the various Linux commands available on the Digi CM. This is simply a listing of commands and does not detail what the commands do or give their particular parameters. If you need more information, see the man pages on a Linux system.
Two commands that are very important for saving and applying changes to the configuration files are:
•saveconf: The saveconf command saves the configuration files to flash memory.
•applyconf: The applyconf command immediately applies the configuration changes.
The configuration files are located in /tmp/cnf directory.
Two system utility menus that are important for accessing and configuring the Digi CM and the serial ports are the portaccessmenu and configmenu.
•portaccessmenu: This menu allows the user to access the serial ports on a Digi CM.
•configmenu: This menu enables the system administrator to configure the Digi CM. It has essentially the same functionality as the web interface for configuring a unit with the exception of the ability to create custom menus.
•portreset #: This command allows the user to reset a specific port. It restarts all processes associated with the port.
