FreeBSD Post Install Steps

Introduction

Everything on this page needs to be done as root, unless specified, so su to root.

su -

Set hostname

echo 'hostname="phoenix.xw.is"' >> /etc/rc.conf

Update the software

freebsd-update fetch
freebsd-update install

Install basic software

pkg install -y bash sudo rsync tmux

ZFS

If you don't have ZFS root (e.g. cloud computing), you might want to create a separate ZFS pool.

echo 'zfs_enable="YES"' >>/etc/rc.conf
service zfs start
zpool create -m /tank tank xbd1
zfs set compression=on tank

Create a user

This will create a user with a random password that can do passwordless sudo:

pw useradd -n aram -c 'Aram Havarneanu' -g staff -G wheel -m -s /usr/local/bin/bash -L staff -w random

Enable passwordless sudo for the staff group:

echo '%staff ALL=(ALL) NOPASSWD:ALL' > /usr/local/etc/sudoers.d/91-staff-no-password

SSH

For ssh access, use su to switch from root to the user and then add ssh keys.

su - aram
# as a user
mkdir -p .ssh
echo 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJnkro8LT0TS+NTOIB787wfqIwv2VTmXXYsnsoVk71UE aram@horizon.local' >> .ssh/authorized_keys
echo 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIC8dcfsqZJWTNTCfATbD6WiZyWoK3AiihynONRjCrtMw aram@oceanic.local' >> .ssh/authorized_keys
echo 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIMRc0UWKrFpCv/EOUo2jpEQt+C/pa0tc1rUWKgjbKTp7 aram@edengate.local' >> .ssh/authorized_keys
chmod 700 .ssh
chmod 644 .ssh/authorized_keys
