PPPoE reconenction fix - mpd fix ($100)

xbipin · May 24, 2012, 9:02 AM

ermal, at least you are monitoring ::)

Looks like I've found the solution, that works at least for me
I've added two lines to the end of ppp-linkdown

ifconfig em0 down
ifconfig em0 up

And looks like reconnection bug is gone.
P.S. em0 is interface, where PPPoE is
P.P.S. I think it's related to driver.

can u mention the location of the file and where exactly did u put those lines, ill give it a try too

Certainly that will reset the device by doing up/down.
Just not a generic solution :)

Do not forget to replace em0 with your own device name.

xbipin · May 24, 2012, 1:48 PM

how do we find out the device name?

marcelloc · May 24, 2012, 2:03 PM

@xbipin:

how do we find out the device name?

on status interface, you can see interface name and device.

WAN interface (em0)

xbipin · May 24, 2012, 2:07 PM

on that it shows this
WAN interface (pppoe0)

where as im using a alix and my wan port is vr1 so should i use pppoe0 or vr1?

w0w · May 24, 2012, 2:16 PM

vr1

You need to restart physical (port) interface, not virtual PPPoE, that I've tried to do also, by killing mpd and starting again with no luck

xbipin · May 24, 2012, 2:15 PM

well then i see this

xbipin · May 24, 2012, 2:20 PM

anyways i tried vr1 and rebooted and checked, it fixes the issue partially, meaning, if my isp fiber optic device is switched off and on then pfsense would connect fine once the device is booted which means one issue solved, but there is a reset switch on that isp device and suppose if i press that then once its booted, pfsense wont connect and fall into endless reconnection loop and one easier way to solve this is to pull the wan wire which connects isp device to pfsense and then pfsense reconnects instead of rebooting pfsense

xbipin · May 24, 2012, 2:26 PM

yes there was vr1 on it.

this means when power is on on the isp device port coz its reset then the solution doesnt work but if its switched off and on or cable unplugged then the port looses power and then once reconnected pppoe reconnects fine.

the reason y i try to do the reset scenario coz in a few instances, the isp device gets a firware update and then it reboots, this leaves the power on and then pfsense wont reconnect

You can also not to push reset switch on your magic ISP device :) Just power off and on to reset it 8)

Can you show the System and PPP log, when you have pressed the reset switch and pfsense won't reconnect?

xbipin · May 24, 2012, 2:38 PM

like i said, i dont need to reset it, but due to a firmware update from isp or even a remotely trigerred reboot from isp causes this, the log is same as here

w0w · May 24, 2012, 2:48 PM

I hope that you have restored your original pppoe-linkdown file after playing with
/usr/sbin/ngctl shutdown $1:
and
/usr/local/sbin/pfSctl -c 'interface reload $iface'
that was suggested in november 2011

w0w · May 24, 2012, 2:56 PM

And I can't see system log anywhere, PPP only

xbipin · May 24, 2012, 2:58 PM

yes the linkdown file is the standard one without any edits coz those edits didnt help, ill get u the system log now, frankly speaking i have already posted logs so many times that i got tired of doing the same again and again when some1 tries to help

xbipin · May 24, 2012, 3:11 PM

here r system log and ppp log when isp device reset

I can't see any other software fix, instead on initiating reboot. This looks like more complex problem then driver or mpd only. So we need to write the if function to the ppp-linkdown, that checks for running shutdown process, and if it does not exists, starts one like 'shutdown -r +10', that means if script is running for the first time it always wants to restart pfsense after 10 minutes. And we need to add one line only to the ppp-linkup that looks like
'pkill shutdown'.

I don't have knowledge to write the if function correctly, so I just added to the end of ppp-linkdown
shutdown -r +1

and

pkill shutdown
to the ppp-linkup file.
Every reconnect starts own shutdown process but you don't have them much in one minute (yes +1 is a minute) before first of them restarts the pfsense. And if the PPPoE is coming up in less then 1 minute then shutdown process will be killed.
It would be good if somebody helps to write if function described above.

My friend suggested me to modify his old SQL check script, so it would be

ppp-linkdown


#!/bin/sh
if [ -f /tmp/$1up ] && [ -f /conf/$1.log ]; then

Please use 'shutdown -r +5' instead of 'shutdown -r +10'
I've found that it is impossible to kill the shutdown process if using +10 (10 minutes).
When tested I've used less then 5 minutes delay.

*** System shutdown message from root@pfhacom.xxxnetxxx ***

I can kill the process by pkill shutdown. WTF? What am I doing wrong?

If I start shutdown -r +10 or any number in console, I can always kill it.~~~~
