set up new linux box

Debian box setup

Additional config:

• development box

create user

su
useradd -m -s /bin/bash catalin

install and configure sudo

su
apt install sudo
usermod -aG sudo catalin

enable non-free apps

Edit /etc/apt/sources.list and add non-free to the end of all lines.

set up ssh server

sudo apt install openssh-server

Add ssh key to ~/.ssh/authorized_keys.

Disable SSH password login by setting PasswordAuthentication no in /etc/ssh/sshd_config.

set up ssh key

ssh-keygen -t ed25519 -a 100

the -a option specifies the number of KDF (key derivation function) rounds used. Higher numbers result in slower passphrase verification and increased resistance to brute-force password cracking (should the keys be stolen).
