Ubuntu 11.04 Standard Install and Basic post install configuration

Install Ubuntu 11.04
Simply use the CD, DVD or USB to install vanilla Ubuntu Linux install.

Setup Static Network Interface configuration
Uninstall Network Manager so that your network does not rely on your desktop login.
sudo apt-get remove --purge network-manager*
cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth1
iface eth1 inet static
#auto wlan2
#iface wlan2 inet static
#wpa-ssid SSID

Setup DNS or Nameservers for dns resolution
Network Manager automatically tries to populate nameservers upon initial configuration so if you uninstalled network manager dns entries may still exist in config file. Modify /etc/resolv.conf to update your nameservers that I usualy use Google's open DNS nameservers.
vi /etc/resolv.conf
nameserver x.x.x.x

sudo /etc/init.d/networking restart

Install and Configure SSH Server
sudo apt-get install openssh-server
sudo sudo vi /etc/ssh/sshd_config
Modify Port to listen on a port different than usual port 22.
Port 2222
Restart SSH Server
sudo /etc/init.d/ssh restart
Test SSH connectivity on required port
ssh localhost -p 2222

Update your repositories and Upgrade packages to latest versions
sudo apt-get update && sudo apt-get upgrade -y

Install and configure VNC Server for remote X Windows connectivity
sudo apt-get install vnc4server fluxbox
vncserver :1
Enter password for VNC session
vi ~/.vnc/xstartup
Modify default Window manager to fluxbox for better performance
fluxbox &
#x-window-manager &
Now restart vncserver
vncserver -kill :1 && vncserver :1

Connect from your Linux or Windows remote desktop
vncviewer x.x.x.x:1

sudo apt-get install ufw gufw
sudo ufw enable
sudo ufw logging medium
sudo ufw allow 80/tcp
sudo ufw allow 53   
sudo ufw allow 8080
sudo ufw allow from
sudo ufw allow from
sudo ufw allow 2222/tcp
