Requirements
To install such a system you will need the following:
linux26 at the boot prompt to install a 2.6 kernel)Now let's install some software we need later on and remove some packages that we do not need:
apt-get install wget bzip2 rdate nmap ssh taceroute-nanog links-ssl lynx fileutils iptaf iproute less tcpdump ntp-simple apt-get remove lpr nfs-common portmap pidentd pcmcia-cs
update-rc.d -f exim remove update-inetd --remove daytime update-inetd --remove telnet update-inetd --remove time update-inetd --remove finger update-inetd --remove talk update-inetd --remove ntalk update-inetd --remove ftp update-inetd --remove discard <- Yes
/etc/init.d/inetd reload
Because the Debian Sarge 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.
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
auto lo
iface lo inet loopback
# The first network card - this entry was created during the Debian installation
# (network, broadcast and gateway are optional)
auto eth0
iface eth0 inet static
address 192.168.0.100

up /path/to/your/firewall.sh
# up /sbin/ifconfig eth0 txqueuelen 1000 # 1000Mbits force
Use this firewall.sh as an example.
Edit /etc/resolv.conf and add some nameservers:
search server nameserver xxx.xxx.xxx.xxx nameserver xxx,xxx,xxx,yyy
Edit /etc/hosts and add your new IP addresses:
127.0.0.1 localhost.localdomain localhost server1 192.168.0.100 server1.example.com server1

Create a file /etc/apt/apt.conf and put something like:
Apt::Cache-Limit 67108864;
in it. If it still fails, make that number higher.
Delete the file '/var/cache/apt/pkgcache.bin' and re-run 'apt-get update'.
sudo dpkg --get-selections > package_list.txt
Save the text file on a thumb drive, format the drive, reinstall Ubuntu/Debian, then to a
sudo dpkg --set-selections < package_list.txt sudo apt-get -y update sudo apt-get dselect-upgrade
