Re: [Astlinux-users] Astlinux network check and restart if internet down.

Hi Nedi

It would be better to find out the exact conditions when it fails rather than the shotgun approach which could be risky and introduce other issues.
I would use Monit which checks every minute and is very flexible. E.g.

Check program Check-Script
  path <script path>
  if status = 1 for 3 cycles then exec "/usr/sbin/asterisk -x 'module reload chan_sip.so'"

The script could be something like:
#!/bin/sh -e
SHOW_TRUNKS="$(asterisk -x 'sip show peers' | grep $1)"
if [[ $SHOW_TRUNKS != *"Unspecified"* ]] && [[ $SHOW_TRUNKS = *"UNKNOWN"* ]]; then
echo "Trunk needs a reload"
  exit 1
else
echo "Trunk is normal"
  exit 0
fi

You could also do a ping check in the script.

Subject: [Astlinux-users] Astlinux network check and restart if internet down.

Hi, i have trouble with one bx and message rejected after internet going down for some time.

I found this script, but I’m not sure if I can use this  on Astlinux.

Can anyone help me to adapt this to Astlinux I would like to check internet and if internet connection broke and coming again I would like to restart asterisk if no registered.

I think I need  an script in combination with a cron job that check if registration fail. If registration fail then make sip reload.
And if Internet going down for some time and up after some time, I would like check that and if internet UP an the registration fail or rejected. I would like reboot PBX or only Asterisk…

could be something like thiis what I found:

asterisk -rx " sip show registry" | grep -w Unregistered && asterisk -rx " sip reload"
I found this to on the net. Can someone help me to combine those two cron.


asterisk restart if the net is down and once a
day just before 7am:
crontab -e:
55 6 * * * /usr/sbin/asterisk -r -x "restart gracefully" >/dev/null 2>&1
5,10,15,20,25,30,35,40,45,50,55 * * * * /root/scripts/check_net

/root/check_net
#!/usr/bin/perl
$net=`/bin/ping -c 02 google.com<http://google.com> 2>&1 | /bin/grep -c 'unknown host'`;
if ($net==1) {
print `/bin/date`;
print `/usr/sbin/asterisk -r -x "restart gracefully"`;
}
