asterisk users - Oct 2006 - alive check for HA constellation

Hi,

I have setup two asterisks with ucarp, to build a HA cluster. Everything works 
fine, if one of the machines is going to die completely. But if the asterisk 
software is running, but "behaving" not correctly, this cannot be
detected by
the ucarp software. 

I think I need a script that periodically checks the master, and if the answer 
is not the expected one, the slave shall try to take over the master. 
I can imagine this will work when I try to check whether I can successfully 
authenticate via SIP to the asterisk. Just pipe it through netcat, and wait 
for the answer. but I have the feeling that I am not the first one with that 
problem, so I want to ask for more easily/robust tests to make sure the master 
is running or not.

any suggestions are appreciated.

kind regards
Sebastian

Hi Leonardo,

I had the problem, asterisk was running, the port was open, but I 
misconfigured Asterisk that way, that it was impossible, to register on the 
asterisk. As it seems to me, hapm can only check whether a port is closed or 
open. unfortunately I do not understand that brazilian portugese.
