Duet pi GUI

BearcatTD

So I installed the latest Duet Pi with the GUI. I updated the WPA-supplicant file with all of my wifi options. DuetPi starts up and connects to the internet fine. But I cannot tell which SSID that the pi is actually connected to. I ran hostname -i and it came back with 127.0.0.1. The problem is none of my APs produce ip addresses in that range. I have internet access, but I need to know where I am connected and what is the right ip address. I need to know this so I can ssh into the pi.

The selection of apps available is pretty slim...I get it, don't want the machine bogged down. I tried to do an apt-get upgrade / update...no joy.

Any help would be appreciated.

ifconfig (or sudo ifconfig) will give you a more detailed list of network addresses.

i suspect iwconfig will do the same for the wifi name

(no idea where those things are in the gui unfortunately)

edit: 127.0.0.1 is a special addres for loopback testing, refered to localhost. it doesn't go anywhere; weird hostname -i outputs it if it has other addresses.

Thanks! I do the ipconfig, then arp -a, which gives a list of all ip addresses connected to each AP. Nothing new shows up.

that had me raise an eyebrow; for several reasons

arp is only a mac to ip address mapping, and only populated and cached for 2-5 minutes for addresses the host has connected to
it will not include the hosts own address under any circumstances i think where did you run arp -a?

edit: I'm thinking your pi is probably not connected to the internet or any network for that matter; but puzzled what would make you think it is. erase and rewind a little - how do you interface to the pi currently?

BearcatTD

arp -a runs on mac after ifconfig and on Windows after ipconfig

ah, i assumed you'd run this on the Pi, as that is where it would have made sense to run hostname -i neither command would have done you any good outside of the Pi.

also note ifconfig , not ipconfig for the Pi.

This is what I thought you'd be after, and wanted you to try:

YES! I did this about 5 seconds before your post came through...LOL Thanks!

Did you resolve the issue?

BearcatTD

@bearer It did! Now I just need to figure out where and how everything plugs in!

@BearcatTD
Can you tell me how you installed duetpi? I've been trying for 2 days. I downloaded duetpi.zip, used balena etcher. Put it into the raspberry pi model 3. And all I get is a black screen with some codes but it stops there.

You should probably create a new topic and include "some codes" to get help with your problem.

@tekstyle I downloaded the duetpi file with the full GUI. I connected the pi to the duet 3 with the ribbon cable. Did you edit the wpa_supplicant.conf? So you can connect to wifi. If you haven't done this yet, make sure you use a good text editing app (I swear by Atom), as Windows and Mac stock apps sometimes put weird line breaks and other funkyness in the files.
