[Solved/hotfixed] SQM does not reinitialize after ifdown/ifup

Kherby · June 4, 2018, 7:00pm

Ok i'll give it a try in a few mins, cant't kill the wan right now as my wife is using the internet for video chat at the moment...
And i should have enough space at the overlay partition, i'm using a WRT3200acm @Davidc's latest build.

The version I recommended for you will require that you start with a single “ifdown wan” and then with “ifup wan” from that point on things should work automatically again.

I assume that you are talking about the cron job for the pppoe/wan reconnect right ?

0 8 * * * ifdown wan; sleep 30; ifup wan

Would/should this one work ?

Best Regards !!

Oh, I had simply thought you log into the router using putty and issue "ifdown wan" to clean things up, followed by "ifup wan" to see whether things work as expected. After that things should just work with or without the cron script... Now please test whether things work and holler if there are still issues...

regarding cron, I am no expert, but 0 8 * * * looks like everyday at 8 o'clock in the morning correct? And yes "ifup wan" seems required as "ifup pppoe-wan" will just throw an error (but you know that already!). So from my limited experience this looks like it should work.

Kherby · June 4, 2018, 7:51pm

Me neither lol... a few guys at this forum helped me to set it up / figure out the right commands.
And you are correct, 0 8 * * * is 8 in the morning but i can easy set it up for testing at another time... For example 55 21 * * * (21:55 evening)
ifup pppoe-wan didn't worked out for me the last time, only ifup wan worked.

I'll definitely let you know if it works for me !!

@moeller0
It doesn't seem to work (for me)...
I've typed the command via putty and did ifdown wan + ifup wan after and speeds went back to default state (no SQM/QOS at all)
Then i rebooted the router, tested and SQM was working. Did ifdown wan + ifupwan again and speeds went back to default (without SQM), type the command again, did ifdown wan + ifupwan and speeds remain the same...

Am i doing something wrong ?

edit:

root@WRT3200ACM:~# cat /etc/hotplug.d/iface/11-sqm
#!/bin/sh

[ "$ACTION" = ifup ] && /etc/init.d/sqm enabled && /usr/lib/sqm/run.sh start ${DEVICE}

As far as i can tell tc -s qdisc shows after ifup wan that it should actually work @dev pppoe-wan but for some reason it's not...

Confirmed the issue and the fix.
I have a PPPoE DSL connection, and my ISP force an IP renewal every 17 ~ 24 hrs, which forced me to restart the SQM service once a day.

I think this fix should be applied to the packages repository, and also backported to the 18.06 branch.

@tohojo What do yo think? it seems you are the package creator/maintainer.

moeller0 · June 5, 2018, 7:43am

Sorry, I did careless copy and paste and did not check the result, the straight quotes in my command line above got replaced by typographic/curled quotes and the shell most likely did not fancy that.

Your cat result confirms that the change did not make it into 11-sqm so you could not expect any different behaviour from before.

Let's try again This time, I will use preformatted text and will not use additional quotes:
Please copy and paste the following into putty (assuming that putty is "connected" to your router):
1)

echo '[ "$ACTION" = ifdown ] && /etc/init.d/sqm enabled && /usr/lib/sqm/run.sh stop ${DEVICE}' >> /etc/hotplug.d/iface/11-sqm

then run the following and post the output here:

cat /etc/hotplug.d/iface/11-sqm

then run the following and post the output here:

tc -s qdisc

then (run & post output)

ifdown wan ; sleep 30 ; ifup wan

and finally (again)

tc -s qdisc

Kherby · June 5, 2018, 8:03am

Yes i was connected to my router via putty.
I'll try it again real quick...

... and you forgot 1)

Kherby · June 5, 2018, 8:11am

root@WRT3200ACM:~# echo '[ "$ACTION" = ifdown ] && /etc/init.d/sqm enabled && /usr/lib/sqm/run.sh stop ${DEVICE}' >> 11-sqm
root@WRT3200ACM:~# cat /etc/hotplug.d/iface/11-sqm
#!/bin/sh

[ "$ACTION" = ifup ] && /etc/init.d/sqm enabled && /usr/lib/sqm/run.sh start ${DEVICE}
root@WRT3200ACM:~#

@4. it should be ifdown wan ; sleep 30 ; ifup wan right ? instead of ipup wan ??

edit: anyway it still doesn't work, still full speed after wan reconnect... it only works when i disable the SQM instance and enable it again or reboot the router.

@takimata does this work for you ?

takimata · June 5, 2018, 8:52am

Okay, that one's on @moeller0, he forgot the full path

It should be:

echo '[ "$ACTION" = ifdown ] && /etc/init.d/sqm enabled && /usr/lib/sqm/run.sh stop ${DEVICE}' >> /etc/hotplug.d/iface/11-sqm

(From the previous incomplete command you now have a pretty, but also pretty useless file "11-sqm" in your /root folder )

ifup wan alone works, too. The one with ifdown, sleep, and ifup is just a little bit more safe. And, yes, this works for me.

Kherby · June 5, 2018, 8:58am

Weird, i really dont know why it doesnt work for me than...
Maybe it's related to the build which i'm using.

takimata · June 5, 2018, 9:05am

So just to confirm, what is the output of

cat /etc/hotplug.d/iface/11-sqm

now?

moeller0 · June 5, 2018, 9:31am

Oops, yes sorry, I actually copied the exact comman line invocation from my last test, but I did not test on the router and cd'd into the directory containing 11-sqm first. Sorry for that oversight!

moeller0 · June 5, 2018, 9:32am

Yes, sorry, not my day apparently

moeller0 · June 5, 2018, 9:33am

I fixed the instructions above, again sorry for the confusion.

Kherby · June 5, 2018, 10:56am

I'm working atm, i will post the output later on as im not at home right now...

Edit: im gonne fix that command first of all, than post the output
Hopefully that will fix the issue...

Kherby · June 5, 2018, 5:33pm

root@WRT3200ACM:~# echo '[ "$ACTION" = ifdown ] && /etc/init.d/sqm enabled && /u
sr/lib/sqm/run.sh stop ${DEVICE}' >> /etc/hotplug.d/iface/11-sqm
root@WRT3200ACM:~# cat /etc/hotplug.d/iface/11-sqm
#!/bin/sh

[ "$ACTION" = ifup ] && /etc/init.d/sqm enabled && /usr/lib/sqm/run.sh start ${DEVICE}
[ "$ACTION" = ifdown ] && /etc/init.d/sqm enabled && /usr/lib/sqm/run.sh stop ${DEVICE}

Does this look correct now ?

edit: I can confirm that it's working fine now !!! Thanks @moeller0 and @takimata for this quick workaround !!

moeller0 · June 5, 2018, 6:08pm

I concur thanks @takimata for getting to the root cause of this!

moeller0 · June 6, 2018, 7:45am

Thanks to @tohojo the openwrt package repository now should contain a fixed sqm-scripts version.
