Auto-rebooting a non-responsive iBurst UTD

[TheLastBoyScout]

Hello all

I am getting frustrating timeouts on my iBurst UTD running over ethernet - I've tried repositioning my UTD with no success. I will try getting an external aerial next.

The PPPoE log on my Debian Linux box shows:

Mar 27 01:49:11 localhost pppd[15155]: Modem hangup
Mar 27 01:50:16 localhost pppd[15155]: Timeout waiting for PADS packets
Mar 27 01:50:16 localhost pppd[15155]: Unable to complete PPPoE Discovery

After this, power-offing the UTD is all that works. I have recently discovered I can telnet into the UTD and reboot it

It connects to the Sandton tower at a signal level of between -90 to -80 (I got these values by telnetting into the UTD).

So I was thinking, is there a script setting that executes on a dropped PPPoE connection that I could set to trigger a telnet to the UTD to execute a reboot?

Anyone done anything like this?

You'd have more luck if you could telnet into the dumb tower and reboot that...

Have the same problem here... every not and then the wick in the tower goes out and ya gotta wait while the thing catches alight again...

Good day TheLastBoyScout

I wrote myself a script and ran it as a crontab every 5 minutes

if ifconfig ppp0
then
echo everything is fine
else
poff
ifconfig eth0 down
ifconfig eth0 up
pon dsl-provider
end if

Sincerely,

Medic

Thanks Medic

I thought of using cron, or a script running permanently and checking every 5 minutes or so. But I would prefer something event driven.

Putting something in the /etc/ppp/ip-down.d directory would work. To make sure I can drop the interface (!), I'm thinking of putting a line in the script to check if the line dropped due to an error, if so then rebooting the UTD.

But I have noticed that you can set the number of retries for a LCP timeout in the ppp config file and wondered if there was a way to tie the script to this event.

Also, has anyone had any luck fixing the issue? Do these line-drops get fixed by fiddling the MTU (I'm running at 1352 - NATting and firewall on my gateway), or using an external aerial?

The firmware update from a while back fixed most problems but an arial should fix the rest, if mounted correctly.
