Linux Console

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

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.
