All Star Link

ASL 3 just came out and it's based on Asterisk 20. Wow, that's a big leap forward for that project. I rejected ASL because it was based on an antique version of Asterisk.

Notes on initial setup

I'm using a new Pi 5 which I have named "ASL", I put a reservation for its addresses (asl.local and asl-wifi.local) into pihole on Bellman.

I have an NVME adapter on order, should come in 3 days. Until then I decided to just mess around with an SD card. Getting an operating system onto the NVME is a trick. You install a full GUI onto an SD card and then run the Raspberry Pi Imager and target the NVME. This is the easiest way, really. It's a squeeze to get an SD card into the Pi when it has the NVME adapter installed because the ribbon cable gets in the way. You can set the Pi to boot first from the NVME or the SD, so it's possible to just leave the SD card in there "for next time" or as a rescue disk.

In raspi-config,

1. Enable serial login under "3 Interfaces"; I do this so that I can work from the kitchen counter with the Pi Debug Module as a serial interface.
2. Enable login over ssh

Remove cockpit, I have no use for it, it requires apache2 and apache2 burns up memory and opens up more attack surface.

sudo apt-get remove cockpit apache2
sudo apt-get autoremove

Removing apache2 breaks allmon3 which might change my mind on that, but I'd prefer to run it on nginx if it comes to that.

WiFi did not get set up during installation. I did it with command line, like this

sudo nmcli d wifi connect "wildsong" password "YOUR SECRET HERE" ifname wlan0

Disable ipv6 by adding this to /etc/sysctl.conf

# Disabling the IPv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Now I have to remember something about Asterisk. Ha. I guess I should go read the ASL project page[1].

NVME

I added the Pimroni NVME interface and wanted to start again.

I did not want to have to mess around with taking the NVME card out to rewrite it so I downloaded the OS image, then used the SD card image to write to it, like this

wget https://downloads.raspberrypi.com/raspios_lite_arm64/images/raspios_lite_arm64-2024-07-04/2024-07-04-raspios-bookworm-arm64-lite.img.xz
sudo rpi-imager --cli *xz /dev/nvme0n1

I set the boot order with raspi-config to be NVME first, then SD card.

I had to edit the config.txt to add these lines to get UART access.

enable_uart=1 
dtoverlay=disable-bt
dtparam=uart0=on

This ends up not setting up an account though, it's back to logging in as "pi". This was a minor problem since I was never able to set the password and so the system was useless. I disconnected the NMVE, booted from SD, set it to boot from SD, reconnected NVME, booted from SD, used commands to mount the NVME, and manually edited passwd, shadow, and group. Then set it to boot from NVME again and finally I am back in business.
