Debian 12
Set IP
Find the interface name.
nmcli c show
Configure IP settings.
nmcli con mod "Wired connection 1" ipv4.addresses 10.13.13.235/24 ipv4.method manual nmcli con mod "Wired connection 1" ipv4.gateway 10.13.13.254 nmcli con mod "Wired connection 1" ipv4.dns "10.13.13.240"
For mutiple IP or DNS settings.
nmcli con mod "Wired connection 1" ipv4.addresses 10.13.13.235/24, 192.168.1.235/24 ipv4.method manual nmcli con mod "Wired connection 1" ipv4.dns "8.8.8.8, 8.8.4.4"
Reset interface
Reset or reboot.
nmcli con down "Wired connection 1" && nmcli con up "Wired connection 1"
Show Settings
nmcli -p connection show "Wired connection 1"
Debian 11
interfaces
make sure the interfaces file has not been modified.
vi /etc/network/interfaces
The default settings are:
# interfaces(5) file used by ifup(8) and ifdown(8) # Please note that this file is written to be used with dhcpcd # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf' # Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d
dhcpcd.conf
vi /etc/dhcpcd.conf
Append the following. The entry of static will stop the server looking for an IP address from DHCP.
interface eth0 static ip_address=192.168.13.200/24 static routers=192.168.13.1 static domain_name_servers=8.8.8.8 8.8.4.4 static domain_search=mydomain.com ap.mydomain.com
Alias
Temporary
To create a temporary alias rather than a permanent one you can issue the following command from the CLI.
ifconfig eth0:0 192.168.22.1/24
IPv6
The domain names servers can have a mix of IPv4 and IPv6 servers.
vi /etc/dhcpcd.conf
static ip6_address=2321:3fa4:4f7a:d100::1234/64 static domain_name_servers=2001:4860:4860::8888 2001:4860:4860::8844
VLAN
Load 8021q Module
vi /etc/modules
Add the line
8021q
Create Interface
Define a VLAN for a specific interface.
vi /etc/network/interfaces
# VLAN 101 Interface
auto eth0.101
iface eth0.101 inet manual
vlan-raw-device eth0
Assign IP Address
Set a static IP for new interface
vi /etc/dhcpcd.conf
# Static IP configuration for VLan.101 interface eth0.101 static ip_address=192.168.1.101/24
Static Route
vi /lib/dhcpcd/dhcpcd-hooks/40-routes
This will add a static route via interface eth0.11 which is on Vlan.11. you could just specify eth0.
ip route add 192.168.0.0/16 via 192.168.99.254 dev eth0.11 proto static
Restart Interface
ip link set eth0 down && ip link set eth0 up
