[arm-allstar] Watchdog if asterisk crashes.

[Doug Crompton]

You can connect a node in two ways for transceive. Either use *73<node> in DTMF from your radio or on the command line in the client.

asterisk -rvvv
rpt fun <yournode> *73<node> 
You can also use lsnodes, iaxrpt, or allmon to connect to a node permanently.

*71<node disconnects a permanent connection.

Permanent means that if node A connected to node B and node B went down (rebooted or restarted) and came back up the connection would re-establish. This includes a disruption anywhere along the Internet path. 

If node A reboots or restarts the permanent connection will not restart unless node A has a startup macro to restart the connection.

A startup macro command is located in the node section of rpt.conf. It is on a per node basis. Here is an example of a starup macro -

In the node section -

startup_macro = *A900

Then in the function section -

A900=cmd,/etc/asterisk/local/startup_commands

The function definition (A900 here) can be whatever you want.

This then calls a script that has the commands you want to execute at startup like in this example -

#! /bin/bash

# Echolink
/usr/bin/asterisk -rx "rpt fun <yournode> *73<node>"
sleep 1
# 223.76 Repeater
/usr/bin/asterisk -rx "rpt fun <yournode> *73<node>"
sleep 1

etc.... any commands you want to execute at startup.
#End of script

I hope I did not confuse you and this was what you were asking!

Doug, could you say more about "started with a permanent connection - *73<node>," like, where is this command inserted (e.g. *.conf, stanza, etc)?

Roselito,

 Not sure what you mean by "crash" ??   This is NOT a common occurrence so I am not sure why it would be happening to you. The hamvoip code has a watchdog that can be implemented in /usr/local/etc/allstar.env.  This is for the system not Allstar. Allstar is started with safe_asterisk which will restart if Asterisk itself crashes.

If you always want Asterisk to start connected to a certain node or nodes you can use a startup macro. Nodes that you want to stay connected should always be strarted with a permanent connection - *73<node>

What image are you using? What conditions cause this? Having multiple nodes connected should NOT cause a crash. Some hub have 30 or more nodes connected without problems.

I have a hub that crashes for some reason. I think it happens when a lot of nodes connect to it?? It usually happens at night.After looking at different watchdog implementations, this is something I came up with after reading Justin Campbells original code. I am submitting this just in case Hamvoip does not have one yet.
