Ubuntu/Linux Server - Switch between tty's

Well for those not used to it and are always working on boring windows displays in stead of performant - back to basics and essentials - character based screens ...

There seem to be six of them.

At startup you are by default using the first.

By pressing ctrl-alt-Fx you can select any of the six tty's.

Ctrl-Alt-F2 will go to the second tty

Ctrl-Alt-F1 will go back to the first (the default in use)

Ubuntu - server - setting fixed ip adress iso dhcp

If Your Ubuntu System has set to use DHCP, you will want to change it to a static IP address here is simple tip

open the /etc/network/interfaces file.

sudo vi /etc/network/interfaces

If you are using DHCP for your primary network card which is usually eth0, you will see the following lines

auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
