Package Manager and SSH 
Setting up package manager 
The Next Thing Co.'s package repository is dead for a long time, but one guy still mirrors them.
You can refer to this page to make the package manager work. Don't forget to sudo apt-get update (I wouldn't risk upgrade though).
Setting up ssh 
To install and enable SSH:
sh
sudo apt-get install openssh-server
sudo systemctl enable ssh.socketYou need
sudoto use commands likeifconfig,shutdown,reboot. Without that they won't even show up 😲
Reboot, then check the IP using sudo ifconfig and issue ssh chip@<ip> on another host. By default the credentials are chip/chip.
Packages 
Right after setting up package manager and SSH access, I've installed these packages to make my life a bit easier.
- vim- instead of quirky- vi
- mc- Midnight Commander is a must for me
