Could you please copy the exact output you get with errors and all? I can see if I can write a crazy filter to get rid of it all. That might be a good bandaid in the interim.

Sure:

Could you try:

echo $speed | sed 's/^[^"]*//'

I'm not seeing any ill effects, so I updated Beta 3... please give it a shot if you had success?

curl --retry 3 "https://raw.githubusercontent.com/ViktorJp/RTRMON/master/rtrmon.sh" -o "/jffs/scripts/rtrmon.sh" && chmod 755 "/jffs/scripts/rtrmon.sh"

Looks great!

I will continue to search for a proper fix for the ipv6 bind issues and let you know if I find anything useful.

Awesome! Thanks for your excellent help with this, @ZebMcKayhan!!

I think I've found a way around it... ipv4 and ipv6 are very different and I don't claims to really know what I'm doing. But the

ip rule add from <wgcX ipv4> lookup wgcX prio 10

makes ipv4 work, the same is not true for ipv6 equivalent. However, adding

ip -6 rule add from all oif wgcX lookup wgcX prio 10

seems to do the trick for ipv6, both ping and speedtest.

For ping, only the target ip type fix is needed but for speedtest both are needed as ipv4 seems required for connection to ookla and then ipv6 for the test servers.

Unfortunately the ipv6 fix does not work for ipv4 either so this must mean that the packet formation must differ or something.

WOW! That's great stuff! I'll get this implemented. You rock!

Looks like this tweak has to be made as well on the rule removal:

ip -6 rule del prio 10

OK, I've made those changes to this latest version of Beta 3, and eliminated the sed cleanup (which I may actually add back in later, because it could help clean up other random garbage I've noticed in the past), but this would be a good test for you!

curl --retry 3 "https://raw.githubusercontent.com/ViktorJp/RTRMON/master/rtrmon.sh" -o "/jffs/scripts/rtrmon.sh" && chmod 755 "/jffs/scripts/rtrmon.sh"

No good

From looking at the code it looks like you commented the ipv4 fix and added the ipv6 fix but as I said, for speedtest both are needed. Ipv4 to get the stuff from ookla otherwise we get the configuration error and no test and the ipv6 fix to take care of test server.

Ahhhh I thought the one ring would rule them all! I'll add the other one back in as well.

I did modify the script locally by
-removing the # on line 3863
-add

ip rule del prio 10 >/dev/null 2>&1

before line 3875

Then it works beautifully:

No errors and I get an ipv6 capable server so the test is ipv6 over wgc1 according to the speedtest binary wishes. I think this is the best we can do until we can force speedtest over ipv4

OK... I've made the necessary changes in Beta 4. Please see if everything continues to function if you don't mind?

Thanks! This version works just the same as my local edit. Great work!

Thank you for all your help troubleshooting this, and making some great recommendations to get around the Ookla Speedtest binary!
