Modifying the Config File

@jimb said in Modifying the Config File:

IP Config from the OS prompt on the Pi yields -
“Link/loopback 'all zeros…”
“inet 127.0.0.0/8 scope host lo”

This should be the first entry of three in the response when you enter ip addr. The next entry should be your ethernet port, and the final entry should be your wireless LAN. My suggestion is to try this on your pi: ip addr | grep inet

Secondly, when Sam told you to switch on SSH, did you go into the config app and do it? You can get to it from the desktop but the fastest way is to type sudo raspi-config and then navigate to “Interface Options”->“SSH”. Make sure it is enabled.

Gents, my goal was not to build a watch, only to tell the time. I have bit the bullet and will be building a new image of the OS and setting it up to run from my PC. That way I’ll be able to copy configs for all to peruse, trying to get Magic Mirror up and running. Thanks for your continued support!

Sam, et all: I have installed a fresh copy of the OS to a new SD card , booted up the Pi, and installed a new copy of the MM2 files, etc. from Sam’s installation script. The only mistake I made was making the MM auto-install. I attempted SSH into the Pi to modify the config on my PC. Had the same “no connnection” issue I had before. However, I now have the IP address of the Pi and I’m not able to ping it from my PC. When the Pi boots this IP address is displayed in the upper right corner for a few seconds so I know it’s correct. An IP config /all display shows-

C:\Users\Owner>ipconfig /all

Does anyone see anything weird?

@jimb that appears to be your windows computer, not the pi.

@jimb said in Modifying the Config File:

only mistake I made was making the MM auto-install.

u mean auto start??? install was my script

ssh doesn’t work unless you enable it on the pi

desktop, menu top left,
preferences
raspberry pi configuration
then the itnerfaces tab, click the slide on the ssh row,
then press ok…

if latest os, then you don’t have to boot

open a terminal window on pi
type

ip addr

you should see like this

pi@raspberrypi4:~ $ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether dc:a6:32:20:b0:94 brd ff:ff:ff:ff:ff:ff
    inet 192.168.2.44/24 brd 192.168.2.255 scope global dynamic noprefixroute eth0
       valid_lft 50521sec preferred_lft 36219sec
    inet6 fe80::a5a6:f1d1:50e7:1c5/64 scope link 
       valid_lft forever preferred_lft forever
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether dc:a6:32:20:b0:95 brd ff:ff:ff:ff:ff:ff

in this setup my wifi (wlan0) is not connected but my ethernet (eth0) is

   inet 192.168.2.44

doesn’t matter what the PC says…

do you have a guest network at home and did u connect the pi to that?

can’t connect to it from home network if so… intentional firewall…

jimb · Dec 1, 2023, 11:41 PM

Sam, the Pi is connected via wireless. Yes, I meant autorun on my first post. I did change the Pi configuration to allow SSH. I have Eero mesh AP’s connected to my home network. I don’t know how to check if access is being blocked to the Pi. Since everything is fresh on the install it makes sense that the network is the culprit. The reason I went with a new install was to enable pasting config, etc. files here on the forum.

sdetweil · Dec 1, 2023, 11:44 PM

@jimb i understand… if you can use a terminal window on the pi, can you ping xxxx, where xxxx is the hostname or ip address of the windows pc?

what is the output of ip addr ?

i know it stinks, but you can post a pic, third icon from the right above the forum post editor

sdetweil · Dec 1, 2023, 11:58 PM

@jimb I’d also suggest trying my MMM-Config module, which presents a form for config.js including outside modules… all done with discovery of the installed modules and there parms…

some modules cause trouble… but there are ways around with some extra work… it may not be for you… another pile of work to learn, it it doesn’t work…

https://github.com/sdetweil/MMM-Config

it doesn’t help with module install, only configure

jimb · Dec 3, 2023, 6:22 PM

Sam,
OK progress on the network front. I spent some time yesterday on the phone with eero tech support. At rhe end they suggested connecting my PC wirelessly and seeing if I could ping the rasberry. It works. I can ping and SSH/Putty into the pi, but have an additional snag. It accepts the login and sends a password request. BUT, I can’t enter anything- the keyboard is dead at that point.

sdetweil · Dec 3, 2023, 8:43 PM

@jimb ok, sounds like the wifi network is a guest, not connected to the regular ethernet network…

don’t use putty

open a cmd.exe window

ssh user_name@machine_ip

add one of the tools

winscp or bitvise ssh clients

they will give you a filemanager view of the files and an ssh window ,
per system you connect to…

bitvise also provides a filemanager view of the pc filesystem , so you can drag/drop files in either direction… (you would only do that for logs to pc, of special bug fix file , to pi)
