Editing Linux network nightmare

== How to configure network ==

At the beginning there was Redhat, with... I don't remember.

Then, there was interfaces. /etc/network/interfaces . Just one file, good.

To configure static ip address:

 auto lo
 iface lo inet loopback
 
 auto eth0
 iface eth0 inet static
 address 10.91.40.20
 netmask 255.255.0.0
 network 10.91.0.0
 gateway 10.91.50.1
 broadcast 10.91.255.255

In the new versions, this must be activated, unactovating eth0 for NetworkManager. In /etc/NetworkManager/NetworkManager.conf, set:

 [main]
 plugins=ifupdown,keyfile

 [ifupdown]
 managed=false

 [device]
 wifi.scan-rand-mac-address=no

and then edit interfaces.

Test it with a reboot!

= Wi-Fi =

Use nmcli (and comment eth0 in interfaces):

 nmcli device wifi connect Benediktinai password Daukanto21

It won't restart at boot!
