4 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

 

5 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.

 

6 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 Feisty Fawn server and follow the remaining steps from this tutorial.

 

7 Edit /etc/apt/sources.list And Update Your Linux Installation

Edit /etc/apt/sources.list. Comment out or remove the installation CD from the file and make sure that the universe and multiverse repositories are enabled. It should look like this:

vi /etc/apt/sources.list

deb http://de.archive.ubuntu.com/ubuntu/ feisty main restricted
deb-src http://de.archive.ubuntu.com/ubuntu/ feisty main restricted

## Major bug fix updates produced after the final release of the
## distribution.

Then run

apt-get update

to update the apt package database and

apt-get upgrade

to install the latest updates (if there are any).

 

8 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.

Hi there, great how-to!

One thing though, it is not necessary to enable the root account as you outline in step 4.

Instead, try: 

sudo -s

 This will give you the root shell.

Instead of rm -f /bin/sh ln -s /bin/bash /bin/sh which leaves no /bin/sh for a few moments. Anything that needs /bin/sh to exist that tries to run before it's recreated will have big trouble. This is a bad habit to get into, especially when you're working with symlinks to libraries. Instead, do ln -sf /bin/bash /bin/sh and it's all done in a single command which guarantees that there isn't even a nanosecond during which there is no /bin/sh.
