Alpine Linux

Introduction

Alpine Linux is an independent, non-commercial, general purpose Linux distribution designed for power users who appreciate security, simplicity and resource efficiency. A minimal installation to disk requires only 130MB of storage. It is used in the majority of Docker container images and installs only about 8MB of operating system software.

Networking

Fix SSH Failure

If you enable root login and see this error...

ssh root@192.168.0.106
Received disconnect from 192.168.0.106 port 22:2: Too many authentication failures
Disconnected from 192.168.0.106 port 22

Then instruct ssh to only use the authentication identity files specified on the command line...

ssh -o IdentitiesOnly=yes root@192.168.0.106

Fonts

To set a large font on the console command line...

apk add terminus-font
setfont /usr/share/consolefonts/ter-132n.psf.gz
nano /etc/conf.d/consolefont
rc-update add consolefont boot
reboot

Raspberry Pi

OK, so ignore the instructions and don't use the latest version!

Download version 3.13 for RPi4...

/dev/sda1  *      2048   503807   501760  245M  c W95 FAT32 (LBA)
/dev/sda2       503808 15548415 15044608  7.2G 83 Linux

Add the usercfg.txt tweaks...

mount /dev/sda1 /mnt/usb/
nano /mnt/usb/usercfg.txt

disable_overscan=1
enable_uart=1

Boot first time, log in as root with no password and run...
