Linux Console

Linux Console

AlphaCom XE runs a Linux distribution from Timesys, kernel ver. 2.6. Linux uses a Command Line Interface (CLI).

In the field the Linux Console can be used for:

• Collect information for debugging purposes, e.g. SIP Trace
• Flash Image update – Recovery of file system
• Start the TST Console: Direct access to the AMC-IP memory (NVRAM)

The Linux Console can be accessed on two ways:

• Via the ethernet port using ”telnet”
• Via serial port 1

Linux Console - Telnet

Start the Windows command line

Type telnet <AMC IP-adress>

Username: alpha
Password: com
The Telnet port (23) is by default disabled in the firewall

Linux Console – Serial Port

Use a terminal program (like HyperTerminal) connected to serial port 1<br\> Communication parameters:

• 115.200 baud
• No parity
• 8 databits
• 1 stop bit

Turning AMC dipswitch S601-1 ON disables AlphaPro over IP

Some Linux commands

ping <IP-address> (Checks communication against external device)<br\>

ps -A (List running processes)

ls -l (list files)

/sbin/ifconfig (list IP adresses etc of ethernet ports)

netstat -a (list network connections)

The Linux console runs the "bash" shell. Documentation for Linux commands: die.net/doc/linux

The TST console debug function of the AMCD application can accessed from linux console. Tracing of SIP is also possible.
