Debian interfaces manual up

Where auto starts the interface at boot and iface calls the network interface (in this case lo, loopback). All lines beginning with “auto” specify the interfaces which will be enabled when running “ifup -a”, a command executed at boot. Lines . Network interfaces are typically initialized in "www.doorway.rue" for the lo interface and "www.doorway.rue" for other interfaces on modern Debian desktop system under systemd. Debian can manage the network connection via management daemon software such as NetworkManager (NM) (network-manager and associated packages). ifup brings the named interfaces up in the order listed. Lines beginning with "allow-" are used to identify interfaces that should be brought up automatically by various subsystems. This may be done using a command such as "ifup --allow=hotplug eth0 eth1", which will only bring up eth0 or eth1 if it is listed in an "allow-hotplug" line.

Where auto starts the interface at boot and iface calls the network interface (in this case lo, loopback). All lines beginning with “auto” specify the interfaces which will be enabled when running “ifup -a”, a command executed at boot. Bring up your interface and verify the connection: # ifup wlp2s0 # iw wlp2s0 link # ip a. You can manually bring your interface up and down with the ifup and ifdown commands. If you added allow-hotplug wlp2s0 as in the example above, the interface will be brought up automatically at boot. There are two commands to enable and disable an interface, manually. Up to Debian 8, use “ifconfig eth0 up” or “ifup eth0” to enable the interface. From Debian 9, use “ifup eth0”, only. The counterparts are “ifconfig eth0 down” and “ifdown eth0”. The image below shows the default output when enabling an interface. Interface activation using ifup.
