Motivation

We all want to learn something about network, such as DNS, DHCP, HTTP and so on.

Understanding the Protocol

DNS

A DNS server can give client IP address when client has the domain name, and give domain name when it has IP address.

DHCP

A DHCP server can assign IP address (both ipv4 and ipv6) to clients.

Web

A web server can let client access the web page in the web server.

Back-up

Back-up service can back-up all the configure files to one server.

VPN

VPN server can allow client log into a Virtual Private Network.

NFS

NFS can create a shared directory between server and client

NIS

NIS server can manage all the users. Client can log in the users which exist in NIS server.

The Requirements

1.DNS

2.DHCP

3.Web server & Firewall

4.Back-up

5.VPN

6.NIS

7.NFS

8.DNS slaves

Progress

Friday, November 22 By Lin Zhu

DNS server can basically work now. It has been tested.

Web server can basically work too, and it has been tested, but not firewall yet.

Working on DHCP right now,it is almost done, but not be tested yet.

All the details will be update by Monday, November 25. By Lin Zhu.

Sunday, November 24 By Lin Zhu.

DHCP server can work on both ipv4 and ipv6 now, and it has been tested on Dual Boot.

Firewall works, and it has been tested.

Back-up server works, and it has been tested.

All basic requirement has been realized.

Monday, November 25 By Lin Zhu

VPN has been done, and tested successfully.

NIS has been done, and tested successfully.

NFS has been done, and tested successfully.

I'm trying to think about other add-ons.

Thursday, November 28 By Lin Zhu

DNS master and slave has been done, and tested successfully.

All the basic requirement and add-ons has been tested again, and they all work normally.

I'm trying to finish the report and prepare for the demo.

Testing

Test plan

Connect together and test one by one.

All the details are in our report(Testing part)

There are lots of screenshot that I cannot upload here, they all in our report, please check it!

Future Prospects

Expansion

DNS is the way forward. Without it companies, online shops, banks, governments and home users will continue be susceptible by threats the original DNS.

FIS is a new technology in 2010. In that year, the professor said that FIS will instead the old things.

Growth

We learned DHCP, VPN, DNS, backup, firewall, NFS and NIS how to work in this project.

All of these above are useful in our life. Even some of these have not been learn in the class, our group had a good job in last 2 weeks.

We learned DHCP and DNS in Fridays class which called TSMG 5330. We learned NIS and NFS by ourselves.

We learned the important of the firewall. Actually, security is the most important things in our life.

Improvements

Backup is the best way for people who work for computer programmer. In my opinion, backup is the way to survive the things what you want to save and which do not exist. In our project we luckily to use it once. A good behavior for us is use back up in our project.
