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.

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

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

Accessing the Linux Console via serial port

Connect the PC to serial port 1 of the AlphaCom

If for some reason the Linux Console cannot be accessed via the ethernet port, it is possible to get access via serial port 1.

  1. On the AMC-IP board, turn dip-switch S601-1 in the ON position
    • Note: AlphaPro will not be able to connect to the AlphaCom while the switch is in this position
  2. Connect the Com-port of the PC to serial port 1 of the AlphaCom
  3. Start a terminal program (e.g. HyperTerminal) with the following communication parameters:
    • 115.200 baud
    • No parity
    • 8 databits
    • 1 stop bit
  4. Press Enter, and you will be prompted for username and password:
    • Username: alpha
    • Password: com
  5. You are now logged in to the Linux Console
Location of dip-switch 601-1

Remember to turn dip-switch S601-1 back to OFF position when finished. Else AlphaPro will not be able to establish communication with the AMC-IP.
