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.

Run

sudo passwd root

and give root a password. Afterwards we become root by running

su

 

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):

vi /etc/network/interfaces

# 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
# The primary network interface
auto eth0
iface eth0 inet static
        address 192.168.0.100
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1

Then restart your network:

/etc/init.d/networking restart

Then edit /etc/hosts. Make it look like this:

vi /etc/hosts

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
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Now run

echo server1.example.com > /etc/hostname

and reboot the system:

shutdown -r now

Afterwards, run

hostname
hostname -f

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.

 

6 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:

vi /etc/apt/sources.list

#
# 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

Then run these two commands:

apt-get update

apt-get upgrade

 

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.

Just a small comment:

There's really no need to enable the root account as explained in section 3.

You might as well use

sudu su -

to switch to the root for doing administrative tasks

 

Just my two cents :-)

Just some comments as I'm going throgh this How-To: 

Sudo is in Ubuntu for a reason and it should be used, so instead of enabling root and setting a root password, run sudo w/ a ' -s ' argument:

sudo -s

That'll put you in as root and you won't have to prefix all of your commands with sudo.

In step #5, instead of restarting the box, you can reload the hostname via /etc/init.d/hostname.sh; faster then restarting the box.
