Commands appended with ‘*’ come from Busybox (the “Swiss Army Knife” of embedded Linux), found at http://www.busybox.
net/downloads/BusyBox.html.
Others are generic Linux commands. Most commands use the -h or --help argument to provide a terse runtime description of
their behavior. More details on the generic Linux commands can found online at http://en.tldp.org/HOWTO/HOWTO-INDEX/
howtos.html and http://www.faqs.org/docs/Linux-HOWTO/Remote-Serial-Console-HOWTO.html.
Using the ls command lets you view all the commands available in your console server’s /bin directory.
A number of Tripp Lite tools listed above make it easy to configure the console server and ensure the changes are stored in the
console server’s flash memory. These commands are covered in the previous chapters and include:
• config allows manipulation and querying of the system configuration from the command line. With config, a new
configuration can be activated by running the relevant configurator, which performs the action necessary to make the
configuration changes live.
• portmanager provides a buffered interface to each serial port. It is supported by the pmchat and pmshell commands,
which ensure all serial port access is directed via the portmanager.
• pmpower is a configurable tool for manipulating remote power devices that are serially or network connected to the
console server.
• SDT Connector is a java client applet that provides point-and-click SSH tunneled connections to the console server and
managed devices.
There are also a number of other CLI commands related to other open source tools embedded in the console server,
including:
• PowerMan provides power management for many preconfigured remote power controller (RPC) devices. For CLI details,
go to http://linux.die.net/man/1/powerman.
• Network UPS Tools (NUT) provides reliable monitoring of UPS and PDU hardware and ensures safe shutdowns of
connected systems. The aim is to monitor every kind of UPS and PDU. For CLI details, go to http://www.networkupstools.
org.
• Nagios is a popular enterprise-class management tool that provides central monitoring of the hosts and services in
distributed networks. For CLI details, go to http://www.nagios.org.
