4 Install The SSH Server

If you didn't install an SSH server during the basic system installation, you can do it now:

apt-get install ssh openssh-server

From now on you can use an SSH client such as PuTTY and connect from your workstation to your Debian Squeeze server and follow the remaining steps from this tutorial.

 

5 Install vim-nox (Optional)

I'll use vi as my text editor in this tutorial. The default vi program has some strange behaviour on Debian and Ubuntu; to fix this, we install vim-nox:

apt-get install vim-nox

(You don't have to do this if you use a different text editor such as joe or nano.)

 

6 Configure The Network

Because the Debian Squeeze 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) (please note that I replace allow-hotplug eth0 with auto eth0; otherwise restarting the network doesn't work, and we'd have to reboot the whole system):

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
#allow-hotplug eth0
#iface eth0 inet dhcp
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

Now run

echo server1.example.com > /etc/hostname
/etc/init.d/hostname.sh start

Afterwards, run

hostname
hostname -f

It is important that both show server1.example.com now!

 

7 Update Your Debian Installation

First make sure that your /etc/apt/sources.list contains the squeeze-updates repository (this makes sure you always get the newest updates for the ClamAV virus scanner - this project publishes releases very often, and sometimes old versions stop working).

vi /etc/apt/sources.list

[...]
deb http://ftp.de.debian.org/debian/ squeeze-updates main
[...]

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:

dpkg-reconfigure dash

Use dash as the default system shell (/bin/sh)? <-- No

 

9 Synchronize the System Clock

It is a good idea to synchronize the system clock with an NTP (network time protocol) server over the Internet. Simply run

apt-get install ntp ntpdate

and your system time will always be in sync.

remember to apt-get update and apt-get upgrade before start 

apt-get install ssh openssh-server

packages change names ... like happen to me a few minutes a go ...
