asterisk users - Mar 2010 - Restarting Asterisk using a script - Thanks to all -

Hi All,

I do have asterisk installed for a call center and I would like to know if
it is possible to create a scipt and execute it from a PC connected to the
Network without accessing the server. This script should restart asterisk
and another service related to aheeva.

The problem now is that each time I have to access using PUTY to the server
to start and run services manually.

Service asterisk restart

Any help would be appreciated, sorry if it is a newbie question.

Regards,

Am

Why do you need to restart Asterisk? Is it crashing (in which case you 
should fix the underlying cause, not just put a band-aid over it) or is it 
not starting when the system is started?

If you are not going to access the server, what event is going to trigger 
the execution of your script?

Hi there,

a. You could (maybe) use PHP and send some command via POST, and (after 
secure/validating the command) use 'exec()' function in php, or 
'system()' function.

Note: that would require to have a webserver with php installed on it.
And allowing the user under which the webserver runs, to restart 
asterisk via sudoers file.

b. You could use a shellscript that sends the command via SSH.

In order to avoid password prompt, you could generate a RSA (or DSA) key 
pair on the machine that will send the command, and copy the rsa_key.pub 
content on your asterisk box 'authorized_keys'.

That would allow you to execute the command remotely via SSH without 
having to insert the password manually.

Note: you could consider using a very limited user on the asterisk box, 
and with sudoers file allowing it just to restart Asterisk.

Hi Steve,

Thanks. Yes it is crashing but as a workaround we restart it and we are
investigating about the root cause.

My question was if it is possible to create a patch script or somthing like
this that we can launch from a PC without directly access the server.

Regards,

The "safe_asterisk" script (which usually lives at 
/usr/sbin/safe_asterisk) can be a useful band-aid or "safety-net."

Hi,

1) It would be nice to find out the root reason that forces you to
restart the Asterisk. I do run Aheeva with decently high uptimes.

2) Both "a" and "b" methods of Jose P. Espinal are
functional, but if
I'm having a failure, I up to grab the putty and investigate what's
going on there :) How often are you having them?

3) what's the another service related to Aheeva, that requires to be
restarted?
