Configuration

Network

See also: https://wiki.debian.org/NetworkConfiguration

Default networking

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
    hostname myhostname

For IPv6 DHCP: 

iface eth0 inet6 dhcp

For IPv6 SLAAC: 

iface eth0 inet6 auto

Bridge

Make sure you don't get an address on you physical interface. Set your interface on manual first. 

iface eth0 inet manual
iface eth0 inet6 manual

auto br0
iface br0 inet dhcp
    bridge_ports eth0
    bridge_stp off
    bridge_fd 0
    bridge_maxwait 0

If you also want IPv6 on the bridge: 

iface br0 inet6 auto
    accept_ra 1

Disable IpV6 Debian

sysctl -w net.ipv6.conf.all.disable_ipv6=1
sysctl -w net.ipv6.conf.default.disable_ipv6=1
sysctl -w net.ipv6.conf.lo.disable_ipv6=1

APT resources

Always use backports on stable 

# stable-backports
deb http://httpredir.debian.org/debian buster-backports main contrib non-free

Debian ansible is a little to old. 

# Ansible
deb http://ppa.launchpad.net/ansible/ansible/ubuntu trusty main

Signal is not in the default repo 

# Signal
deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main

Usage

Luks

Check if your password works: 

cryptsetup luksOpen --test-passphrase /dev/sda5
