After the reboot you can login with your previously created username (e.g. admin). Because we must run all the steps from this tutorial as root user, we must enable the root account now.
sudo passwd root
and give root a password. Afterwards we become root by running
4 Install The SSH Server
Ubuntu does not install OpenSSH by default, therefore we do it now. Run
apt-get install ssh openssh-server
You will be prompted to insert the installation CD again.
5 Configure The Network
Because the Ubuntu installer has configured our system to get its network settings via DHCP, we have to change that now because a server should have a static IP address. Edit /etc/network/interfaces and adjust it to your needs (in this example setup I will use the IP address 192.168.0.100):
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5).
# The loopback network interface auto lo iface lo inet loopback
