I need help to make this work.

this is my configuration:

hobbit-alerts.cfg
HOST=*
        SCRIPT /usr/local/bin/smalert 1234123400 FORMAT=SMS


script
#!/bin/sh
/usr/local/bin/lee '"$BBHOSTNAME" alerta "$BBCOLORLEVEL" servicio
"$BBSVCNAME" con la direccion "$MACHIP" fuera por "$DOWNSECS"'


I'm using the script option in my hobbit-alerts.cfg file because I need
to send a voice alert in my site but it doesn't work.

why ?

Looks ok.

There's a problem with the quoting of this. In most cases I've seen,
when you put something inside single quotes in a shell, then environment
variables are NOT expanded by the shell. E.g.:

   $ echo '"$BBHOSTNAME" alerta "$BBCOLORLEVEL"'
   "$BBHOSTNAME" alerta "$BBCOLORLEVEL"

"doesn't work" is fairly broad. Does your script get called when you
expect it to ? You can put a statement into the script to log something
to a file, so you can see if the script runs at all. My guess is that
the script does run, but your script doesn't do as you expect it to.
In that case, try running your script by hand:

   BBHOSTNAME=myhost BBCOLORLEVEL=yellow \
   BBSVCNAME=conn MACHIP=10.0.0.1 \
   DOWNSECS=120 \
   /path/to/script 1234123400

You can also look at the "page.log" file in the hobbit logs directory;
this captures any error messages generated by your script.

I saw in the page.log this line:

sox: Can't open output file '/dev/dsp': Permission denied

I changed this and now is shouting all my alerts.

root at larissa:~# ll /dev/dsp
crw-rw---- 1 root audio 14, 3 2006-09-07 17:24 /dev/dsp
root at larissa:~# chmod 666 /dev/dsp
root at larissa:~# ll /dev/dsp
crw-rw-rw- 1 root audio 14, 3 2006-09-07 17:24 /dev/dsp


Muchas gracias.
