Debian: Trixie

Notes on the Debian 13 release, Trixie.

syslog

Moving away from traditional text-based files in /var/log, Debian 13 relies on systemd for log management. You can query and inspect these logs using journalctl.

e.g. open a terminal and run journalctl --follow to view logs as they appear.

networking

Edit configuration in /etc/network/interfaces.

Alternatively, you can keep each interface’s configuration in a separate file under /etc/network/interfaces.d/. Files in this directory are automatically included.

static IPs

For a static ipv4 IP, here is an example for enp14s0.

The file is /etc/network/interfaces.d/enp14s0 and contains:

# The primary network interface
allow-hotplug enp14s0
iface enp14s0 inet static
    address 192.168.100.20/24
    gateway 192.168.100.138
    dns-nameservers 192.168.100.138 8.8.8.8 1.1.1.1

For a secondary IP, add an alias.

auto enp14s0:1
iface enp14s0:1 inet static
    address 192.168.100.21/24

Apply your changes

Once your configuration is saved, restart the networking service.

This can drop your active connection, ensure you have an alternative access method before proceeding.

systemctl restart networking
