No connection to web interface using Mac High Sierra


#1

Hi - I received my Mod Duo yesterday. I am unable to access the web UI from http://192.168.51.1/ or http://modduo.local . Chrome does redirect me to http://192.168.51.1/?v=1.5.0.568 - maybe that is the current version I’m running. I can ssh to the server and ping it, but not web UI. I can ping it.

I’m running MacOSX High Sierra 10.13.4. It’s a MacBook Pro (Retina, 15-inch, Late 2013). I see that Duo Ethernet is connected in Network prefs. I tried renewing the DHCP lease but that didn’t help. No proxy settings, default bypass: *.local, 169.254/16.

I am also connected to my local wifi network. I tried connecting after disconnecting from my wifi network, but that didn’t help.

I’ve tried connecting w/ Chrome, Safari, and Firefox without success.

Any tips?

Cheers -

Chris

Are you connecting via USB?

Connection to the computer is via USB and not Ethernet.


#3

I’m only on regular Sierra - how’s the view up there? I checked and I am running v1.5.524. I have occasionally seen update notifications for the .536 version but haven’t updated (or tried once and it didn’t succeed).

Does Chrome display anything after the redirect? As a high-level smoke test, you can check if the UI process is running:

ssh root@192.168.51.1 "ps aux | grep mod-ui"

and you should see similar to this in the output:

root 212 3.1 10.3 119240 106964 ? S<Lsl 00:00 0:17 /usr/bin/python3 /usr/bin/mod-ui

If you’re feeling adventurous you could try installing the .524 version. Here is a link to the image: http://download.moddevices.com/releases/modduo/modduo-v1.5.0.524.tar and there are instructions I think on the Wiki about how to install.


#4

Yes, USB. The Network prefs are a tad confusing - it displays “Duo Ethernet” but I’m actually connected via USB. I think it’s because the USB is emulating an Ethernet device.


#5

Thanks a lot for the debugging help!

Chrome dos not display anything after the redirect. The error message is ERR_CONNECTION_REFUSED.

Good idea re: UI process; yes, it is running.

root      2747  106  1.3  23840 14352 ?        R<s  00:07   0:02 /usr/bin/python3 /usr/bin/mod-ui

I’ll give one of the updated versions to try.


#6

A little update: seems like mod-ui keeps rebooting:

[root@modduo ~]# ps aux|grep ui
root      3378 62.6  1.7  29988 18424 ?        R<s  00:09   0:03 /usr/bin/python3 /usr/bin/mod-ui

root      3670  0.0  0.0   2168   556 pts/0    S+   00:10   0:00 grep ui

I tried to launch it manually, here is the error message. I figured it would clash with one of the re-apwning mod-ui processes, and it did :slight_smile:

[root@modduo ~]# /usr/bin/python3 /usr/bin/mod-ui

I figured out how to kill the mod-ui service - systemctl stop mod-ui.service - and tried launching the command /usr/bin/python3 /usr/bin/mod-ui. Here is the output:

@chrisekelley I’m sorry to hear you’re having those issues with a new Duo.
Let me try to help you. Try downloading the latest image here then do a full re-image.

Steps are:

1 - Turn off your Duo
2 - Connect your USB cable
3 - Hold the left know + left footswitch
4 - Plug the power cable on
5 - Release the switches after you see the Duo light up

The Duo will boot and automatically a storage device will show up in your computer. Copy the .tar file to it and eject it.

Wait a couple minutes and your Duo will go through the re-image process.
If you still see an issue after that, then try running one more time.

If you still see issues after doing it twice let me know.

Cheers,
Alex.

@acunha - thanks for the advice; unfortunately, after the first time of applying the latest image, the web-ui still would not display, and the Network prefs/Duo Ethernet was no longer connected. I tried to apply it a second time, but the storage device would never show. I swapped USB cables, and still no love. I’ve downloaded the files to re-image and will try to start fresh again.

So here is the log of re-imaging my Mod duo:

Continuing from the Factory reset instructions:

  • Power off and on the MOD Duo (by replugging the power cable)
  • Wait until its LEDs turn blue, after around 30 seconds. If the LEDs don’t light up after one minute, replug the power cable once again

No blue lights the first time. Replugged. No blue lights again. Gonna wait ten minutes and see if anything happens, then i’ll try to re-image again.


#10

@ricardocrudo Anything else you can help @chrisekelley with?


#11

Re-imaging again. No blue/green/red lights - but the display is showing

installing restore
installing system
installing user data
updating controller
please wait

It’s been in please wait for about 18 minutes.


#12

OK, it booted up, now it is at version 1.4.3.488

Gonna try to do the upgrade again.


#13

Can no longer upgrade - When I follow these steps:

1 - Turn off your Duo
2 - Connect your USB cable
3 - Hold the left know + left footswitch
4 - Plug the power cable on
5 - Release the switches after you see the Duo light up

The Duo boots but I do not see a storage device in the Finder.

I’ve tried this several times.


#14

Is it possible to do a command-line upgrade - similar to the re-imaging using bootfix.osx? 1.4.3.488 is certainly not working for my mbp.


#15

@chrisekelley Please, download this image: http://download.moddevices.com/releases/factory/modduo-latest-factory-image.raw and proceed using the bootfix.osx command as you did before. After the installing is done, i.e.: LEDs are green, power the Duo off and on again, run the command: ssh root@192.168.51.1 "rm /root/need-self-test && sleep 2 && sync". Finally, power off / on again and check if your Duo is working.


#16

I downloaded and installed the image. It failed the first time, worked the second. I was unable to access http://modduo.local/?v=1.5.0.568 or http://192.168.51.1/?v=1.5.0.568.

I rebooted my mbp again but still no success reaching the web-ui.

When I ssh in and look at ps ax|grep ui, I get a different pid each time.
