Ns2 server will be probably a virtual machine running Debian or Scientific Linux.

Write a new domain name arcluster.eu and created Total DNS in my registrar. With this records I can point my public IP to my server. Pointed ns1.arcluster.eu to my server and tried to run my own name servers. This is the ns1.arcluster.eu.

Create a subdomain in godaddy.

Choose agapiou.net which is the domain that I add a subdomain.

Give a static IP 192.168.10.91 to the server so I know that I have the IP address do not change every time I need to restart or reset my router. The server will require the same address.

Connect to the server using webmin.

Choose File manager and backup the old configuration so I can edit the new one.

Enable port forwarding because my server is behing router with the firewall enabled. So I need to open some ports to have access throught internet. The ports that I opened is for ssh and vnc.

Click on linux_24n5.

VNC is a graphical Desktop sharing system that allows to the users to have access remotely to another computer.

Download and install vnc4server in my server.

VirtualBox is an x86 virtualization software package. Throught VB I will create a virtual machive that it will run NorduGrid middlewar. Using the Ethernet bridging i will combine an ethernet interface with my  virtual interface and bridging them together under a single IP address. From now on I can have access to my machine throught internet by looking for it using it's public IP address.

Search in Synaptic Power Manager for VirtualBox.

Prefer a graphical installer to have screenshots ;)

Webmin is a web-based interface for system administration for Unix. It gives the ability to connect remotely to the other party using your browsing throught secure channel. (uses protocol https).

Download Webmin using wget.

Using apt i downloaded and installed openssh-server. This programs allow me to have access to the server using secure channel.
