3 Enable The root Account
After the reboot you can login with your previously created username (e.g. administrator). 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
iface lo inet loopback
# The primary network interface
iface eth0 inet static
Then restart your network:
Then edit /etc/hosts. Make it look like this:
127.0.0.1 localhost.localdomain localhost
192.168.0.100 server1.example.com server1
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
echo server1.example.com > /etc/hostname
and reboot the system:
shutdown -r now
Both should show server1.example.com.
From now on you can use an SSH client such as PuTTY and connect from your workstation to your Ubuntu server and follow the remaining steps from this tutorial.
Edit /etc/apt/sources.list And Update Your Linux Installation
Edit /etc/apt/sources.list. Comment out the CD and enable some of the other repositories. It should look like this:
# deb cdrom:[Ubuntu-Server 6.10 _Edgy Eft_ - Release i386 (20061025.1)]/ edgy main restricted
#deb cdrom:[Ubuntu-Server 6.10 _Edgy Eft_ - Release i386 (20061025.1)]/ edgy main restricted
deb http://de.archive.ubuntu.com/ubuntu/ edgy main restricted

Then run these two commands:
7 Change The Default Shell
/bin/sh is a symlink to /bin/dash, however we need /bin/bash, not /bin/dash. Therefore we do this:
rm -f /bin/sh
ln -s /bin/bash /bin/sh
If you don't do this, the ISPConfig installation will fail.
