## interface settings are set in /etc/network/interfaces or included files in /etc/network/interfaces.d/
## Example 1, configure every interface in /etc/network/interfaces
vi /etc/network/interfaces
/etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
#
auto enp0s3
iface enp0s3 inet dhcp
#
auto enp0s8
iface enp0s8 inet dhcp
#
auto enp0s9
iface enp0s9 inet static
address 192.168.0.101
netmask 255.255.255.0
## The statement auto means that the interfaces will be brough up when ifup -a is executed
## e.g. the networking service is started.
## Other options for static
## address [address]
## netmask [mask]
## broadcast [broadcast_address]
## metric [metric] (Routing metric for default gateway, integer value)
## gateway [address] (Default gateway)
## pointopoint [address] (Address of other end point)
## hwaddress [macaddress|random]
## mtu [size]
## scope [global|link] (Address validity scope)
## restart the networking service
systemctl restart networking
## Example 2, configure some interface in /etc/network/interfaces
## and some in individual interface files in /etc/network/interfaces.d/
vi /etc/network/interfaces
/etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
