The Linux Console

AlphaCom XE runs a Linux distribution from Timesys, kernel ver. 2.6. Linux uses a Command Line Interface (CLI). This CLI can be accessed via the so-called Linux Console.

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
  • To start the TST console: Gives direct access to the AMC-IP memory (NVRAM)


Accessing the Linux Console

In PuTTY enter the required connection parameters

The Linux Console is accessed via the ethernet port of the AMC-IP.

  • A SSH/Telnet client is required. The free SSH/Telnet client “Putty” is recommended. Download and install PuTTY from here: PuTTY
  • In AlphaWeb, System Configuration -> Filters, enable the SSH port (port 22).
  • Start PuTTY, and enter the IP address of the AlphaCom, select protocol SSH and port number 22. Press Open.
  • You are now prompted for username and password:
    • Username: alpha
    • Password: com
  • You are now logged in to the Linux Console

Note: AMC software version 10 is using the Telnet protocol on port 23, not the SSH protocol on port 22. When accessing an AMC-IP running software 10 you must enable Telnet (port 22) in Filters in AlphaWeb, and select Telnet protocol and port 23 in PuTTY.

Linux Console – Serial Port

Linux3.png

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 useful commands

  • tst -s /tmp/sipd_trace (Start SIP trace - for debugging when SIP Trunk issues)
  • 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)
  • Top (Displays a listing of the most CPU-intensive tasks on the system)


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.
