Hey everybody,

I received an Linksys WRT 3200 yesterday to replace my old Linksys E4200, which seems to be way to old to handle dslite well, but it works.
It doesn't, however, on the WRT 3200 with no clear reason. I tried latest trunk and davids build, but both get no IPv4 connection at all.
dhcpv6 works fine for wan6 on both builds and I can access the v6 part of the www.

When I watch logread it loops mainly one thing very fast:

Sat Apr 7 16:13:42 2018 daemon.notice netifd: Interface 'wan6_4' is setting up now
Sat Apr 7 16:13:43 2018 daemon.notice netifd: wan6_4 (13814): Command failed: Unknown error
Sat Apr 7 16:13:43 2018 daemon.notice netifd: Interface 'wan6_4' is now down
Sat Apr 7 16:13:43 2018 daemon.notice netifd: Interface 'wan6_4' is setting up now

I tried running /lib/netifd/proto/dslite.sh by itself, which returns "./dslite.sh: line 106: add_protocol: not found", when I comment the last three lines it runs without any output.
My shell scripting ability isn't very powerful, so I can't really make any sense of the json* and proto* parts of it.

Funny sidenode: it's the same on the E4200, but there, it works. I can even stop ds-wan (with luci for example) to stop the error flood in logread and I still keep a working v4 connection.

What else could I check? I am fairly new to openwrt, I am using it for exactly one week now So far, I really like what I see, but I really don't know where to look to solve this. Can somebody help please?

Thanks in advance!
Best regards
Tim

Edit: I should add: On the Linksys E4200 I tried everything from 15.05.1 upwards to selfcompiled trunk images, dslite worked on every single one of them with the very same behavior, yet providing a working v4 connection which was slow but stable.

So a little update from me, I tried official 17.01.4 and it's working right now rock solid for the past 3 hours.

Something between 17.01.4 and now broke dslite on WRT3200, what could it be?

Anybody?

I wanted to try the working configs against the others, and maybe try the same version dnsmasq/odhcp that 17.01.4 uses, any thoughts?

Don't have any new info for you. But when you get the error "protocol not found" sounds like you are missing a kernel module.

Hey,

thanks for the info! I have no idea how to verify that though, especially that I only got that error when I run /lib/netifd/proto/dslite.sh by itself.

The only error I get on 17.01.4 is "Wed Apr 11 10:49:31 2018 daemon.notice netifd: wan6 (1287): Command failed: Unknown error", this happens every minute, but the connection works flawlessly.

So, swapping network conf files with the working 17.01.4 doesn't work.. maybe the newest odhcp6c is faulty?

While on a fresh 17.01.4 I can download packages via IPv6 instantly, newest snapshot from today even has a problem with that.
Would support my theory that the newer odhcp6c version has a bug.

To better understand the less-than-useful error. I would suggest running the script manually like this:

sh -x /lib/netifd/proto/dslite.sh

That will show you display as each line is executed, and you will have a better idea of what is causing the error.

Hey cvmiller,
thanks again!

When I run it like that it indeed shows a nice list of steps. I can run the script like that without an error (you have to be in /lib/netifd/proto when you run it since there are softlinks to ../netifd-proto.sh)
There is no error. Of course there is no connection like that.

I tried newest snapshot with odhcp6c from 17.01.4 - with that I get an working IPv6 connection. DS-Lite still fails though.

I'm experiencing the same issue as described here.
With the current stable release of 17.01.4 it does work but not the latest snapshots or with SuperWRT or Davids WRT Version... :worried: Not sure how i can help to fix it

Thanks for running the script with '-x'. I thought you said you saw the error when running it manually.

I agree there is something that is broken, I am just not sure it is odhcp6c. The Devs should be made aware of this problem before the next release of OpenWrt is released (which I thought was going to be this month). But it would be good to know for sure that it is odhcp6c.

Have you ever used strace? It is a great debugging tool for binary apps. You can "attach" it to a running PID, and it will spit out lots of detail, including your error message if it is, in fact, odhcp6c.

Once you capture the error in strace, you can raise that to the Devs, and it will be much easier for them to fix the problem.

Hey,
yes, there was an error before running it without -x, but the error was caused by the last three lines of the script (and I think they just add the protocol to luci?) - yesterday I ran the command with all the parameters that are used in the working environment - that worked fine.

I tried to use strace once or twice, but I wouldn't say that those are success stories. What do you suggest? strace the dslite script? odhcp6c?

I have never tried to strace a shell script (since one can run -x to debug). I would suggest stracing odhcp6c and pipe that to a grep looking for the error. Something like this:

strace -p <pid of odhcp6c> -o - | grep add_protocol

Note: strace normally prints to stderr, in order to pipe to grep tell strace to output to stdout first e.g. '-o -'

Post #14

12 Apr 2018, 18:26

Okay, will do (maybe not tonight, tomorrow then!)

the add_protocol thing, I am still not sure if this is the root of the problem. But we will see what strace will show I'll report back asap

Sorry for the late reply cvmiller!

I straced the script now. Hope it helps, I'll try and read something out of it too

Thanks for the strace outputs. It looks like the new version is looking for 'add_protocol' program but can't find it. Perhaps the snapshot software is a work in progress, and they haven't finished submitting code? Hopefully the Devs will take a look at this, and fix it.

How can we make aware of it? Should we submit an issue to the bugtracker, if yes, how?
Does this only affect dslite or is there something else broken?

Thanks a lot!

I created this bug report: https://bugs.openwrt.org/index.php?do=d … ;pagenum=2

@cvmiller: thanks for all your help! Hope this gets resolved soon!

Hopefully they will get it fixed before the next release of OpenWrt (which I thought was going to be soon). Thanks for doing the debugging.

The discussion might have continued from here.
