How to access the terminal ?

[manju4ever]

I was wondering how do we access the arch linux terminal to install drivers and stuff ?

[WebReflection]

ssh benja@192.-68.1.xxx

Password: benja

The ip to ssh into is the one shown first time you boot your device connected to any dhcp

[maertz]

Is there also a root acc.?

[WebReflection]

root/root I guess

[maertz]

Indeed as you mentioned in your docs but at least within the RPI ISO it doesn't work.

update tried to add a new user just to test but looks like root already exist just with a different password (tried to login with benja, root, password - none worked).

[benja@benja ~]$ sudo useradd -m -g users -s /bin/bash root
[sudo] password for benja: 
useradd: user 'root' already exists
[benja@benja ~]$ 

[WebReflection]

root access via SSH might be disabled .... but you have benja user, with sudo privileges ... so, what are you trying to do that's not already possible?

[maertz]

I tried to rebuild your sample and use the GPIO pins but mine says johnny-five and raspi-io aren't available so I tried to install them the hard way.

[WebReflection]

the hard way? what sudo npm install -g johnny-five didn't work?

[maertz]

Yea I'm basically trying every possibility I can think of (the hard way) ^^ just tried your command on a fresh installed ISO - didn't work, here is the output (RPI Model 3 rev 2).

OK, first of all, IIRC johnny five should be already there. I guess that's not actually the case.

Before you can build stuff on ArchLinux you need dev tools.

However, I suggest you update the whole system first. The current ISO is quite old, you probably have to update this way.

sudo pacman -Syuw
sudo rm /etc/ssl/certs/ca-certificates.crt
sudo pacman -Su

Now you can install developer stuff.

sudo pacman -S --needed --noconfirm base-devel linux-headers git

After that you can try again to install both johnny e raspi-io

I should probably put this stuff in the paper page.

However, this ticket was about connecting via SSH and I've no idea why we're discussing these things in here.

Hard to find for others that might have the same problem :disappointed:

[maertz]

Thanks for the support, I'll start over with a fresh install and try to make it work. Sure I'll create a new ticket to describe the issue I'm having with my RPI3 and maybe send a PR to update the docs :)
