IMHO instead of services-start, it should go to nat-start.
Otherwise, I think cake won't survive a firewall restart.
And nat-start is called also after a firewall restart.

@Xentrk can you share your expertise regarding this? You had the same problem with vpnrouting from your x3mRouting.

A firewall reset would wipe out the iptables mangle table PREROUTING rules. nat-start runs after a firewall restart. Placing the scripts in nat-start would reestablish the routing rules. It would also run the script at system boot.

There’s a previous thread (10+ pages) as well that goes back a year or 2...once an “official build” happened, it was decided a dedicated thread was most appropriate.

And that thread is still referenced in Post 1 in this thread - so definitely still in the mix, but this thread has one standard installer/process, where the original thread had about 3 manual methods to get going

For your further reading @Chris0815 here!

Managed a reboot. After running stable for 10 mins, as previously, I get bad bufferbloat results and no speed capping on a test

Running the status check gives

hodgetts@RT-AX88U-AA80:/jffs/scripts# /jffs/scripts/cake-qos status
> CakeQOS-Merlin v0.0.4 is running
> Download Status:

> Upload Status:
qdisc pfifo_fast 0: dev eth0 root refcnt 2 bands 3 priomap  1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1

After copying and running the command from my services-start

/jffs/scripts/cake-qos start 15Mbit 4Mbit "besteffort bridged-ptm ack-filter"

I get

hodgetts@RT-AX88U-AA80:/jffs/scripts# /jffs/scripts/cake-qos status

Notice the difference in the Upload results from the status

I'm getting the same output for cake_qos status for the upload status. Is this a bug or OK as is and the numbers translate to variables of sorts?

The entry?

> Upload Status:
qdisc pfifo_fast 0: dev eth0 root refcnt 2 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1

I believe it shows that Upload isn't using cake, but instead is using the standard queue mechanisms

Manually moving from services-start to nat-start has certainly fixed the issue at reboot. I'm not knowledgeable enough to know if that's the correct and only place it needs to be.

The stop is still in services-stop.

Currently being looked at. Will wait for @jackiechun and @maghuro as there is a pull request under review that may/should put this to bed...

[Wade Coxon]

Awesome, try taking it up to 95% and see if you still get As
Note, I am just curious...

Sorry, took me a while to get to this, family just gone to bed .

But...well blow me down.
So I had tested 95% before with besteffort, and was getting some nasty bloat, so needed to drop to those sub-85% values.

Tonight's testing is a bit different with diffserv3, I can run 95% very happily!

No QoS test:
D/L Speed = 33.3Mbps (as measured by the Asus Traffic Monitor)
U/L Speed = 9.4Mbps (again measured by Asus Traffic Monitor)

Idle Ping 57ms, D/L 94ms, U/L 94ms. (DSL-Reports B Result)

95% Cake QoS:
diffserv3
bridged-ptm (Australian NBN Fibre to the Node VDSL2)
31600Kbit
8900Kbit

Idle Ping 56ms, D/L 60ms, U/L 61ms (DSL-Reports A+ across the board)


Now that's damn impressive. And RAM usage is still under 60%. Impressed.

Though I may need to build in a little extra slack, because my sync rates do tend to drift a little.

During the course working from home for the day, I did have three odd anomolies.
1) Lost sync on my VDSL modem. Unlikely to have been anything to do with the router. Came good on its own.
2) Lost the Router's web interface, but could still access the net. Just prior to this, RAM usage was under 60%. Rebooted to restore web interface. This isn't a common occurrence, so I will keep an eye on this.
3) Lost Internet from my LAN and WiFi. Router thought it was still online though. Had to manually disconnect and then reconnect to Internet via the web interface and all came good.

something happened with my cake's upload?

If you run the "enable" command does it correct itself? This might be related to the open issue around router restart that's being reviewed.

 

[Wade Coxon]

Not just router restart. Anything that drops the connection will cause the upload qdisc to revert to qdisc pfifo_fast.

it corrects itself if i run "enable" but then it goes back to same state after a few minutes

 

[ttgapers]

Let's see what happens with your experience once 0.0.5 gets out the door. It appears your issue is a bit different where Cake might be abending for some reason....

 

[jackiechun]

I've sent you a PM with v0.0.5 testing instructions if you are able to help

downloading now. will report.

0.0.5 install was flawless and cake is now loaded from "nat-start"
firewall-start and services-star entries removed.

i'll keep an eye to see if i get the abort problem again.

when cake aborts, the only indication will be a message(?) on the system log?


also "Status" no longer reports the version of the script :-/
ah. re downloaded and now it does. that was fast!

 

[heysoundude]

Houston, we have a problem: update didn't work, status returns usage instructions.
do I have to STOP cake to update it, really? What have I done wrong that status doesn't return what the README on github, or the post above this, suggests?

EDIT: ohhh, there's something funky with v0.0.4. Slow down, gents.

Yup...

IF you want to, see my steps on the develop branch (trending to 0.0.5)....

Clean upgrade and as you see the script does Stops of the service on enable command. Also it cleaned up services-start and moved to nat-start. Gonna restart now.

does it make sense for "status" to also display the metrics of:
tc -s qdisc show dev eth0 # for upload
tc -s qdisc show dev ifb9eth0 # for download
