Run Bash Script thrice & then interval for 10 mins.

Hi...

I am very new to shell scripting. I have written a script with help of this forum and some googling and it works the way I want it to. Currently this script checks for my SIP trunk registration every 5 seconds, if registration is not available then it reboots my router through telnet session and keeps rebooting it till the registration is available.

I would like the router rebooted only thrice at max and then wait for 10 minute, check for registration again and if failed then max 3 reboots and interval again.

However if the trunk registration is successful then script should keep checking it every 5 secs as per current practice.

Would be thankful for help provided.

Code:
#!/bin/bash
typeset -i interval=5
run=true
trunk=vonage
while [[ "$run" == "true" ]]; do
checktrunk=$(asterisk -rx "sip show peer $trunk" | grep -c "Status.*OK")
if [[ $checktrunk -eq 0 ]]; then
echo "$(date): SIP trunk registration failed."
sleep 2
{
sleep 2
echo admin
sleep 2
echo password
sleep 2
echo sys reboot
echo exit
} | telnet 192.168.1.1
else
echo "$(date): SIP trunk registration OK."
fi
sleep 5
done
exit 1

Try this:
Code:
#!/bin/bash
typeset -i interval=5
run=true
trunk=vonage
reboot=0
while [[ "$run" == "true" ]]; do
   checktrunk=$(asterisk -rx "sip show peer $trunk" | grep -c "Status.*OK")
   if [[ $checktrunk -eq 0 ]]; then
      echo "$(date): SIP trunk registration failed."
      sleep 2
      {
      sleep 2
      echo admin
      sleep 2
      echo password
      sleep 2
      echo sys reboot
      echo exit
      } | telnet 192.168.1.1
      (( reboot += 1 ))
      if (( reboot == 3 )); then
      	sleep 600
      	reboot=0
      fi
    else
       echo "$(date): SIP trunk registration OK."
    fi
    sleep 5 
done
exit 1

Perfect!

Hi Klashxx,

This is perfect! Just what I wanted, however there's just one small problem.

During the sleep period of 600 secs (i.e ten mins break) the script does not look for registration failed or success.

For logging purposes I would like the script to check if during sleep period the trunk came back online.

If am not askin for much then please help Smilie Otherwise this is perfect and solved for me! Thanks a lot.

So is what you are now asking for is a frequent poll and reboots at 10 minute intervals?

You have all you need really, you just have to adjust your logic and re-use what's been offered. Consider 600 seconds being a 120 x 5 second tests and code a loop accordingly. You'd be better trying and failing, then asking for help than asking for a ready made solution. You will then learn how things work and be better placed to support and adjust them in future.




Regards,
Robin
