Network Conditions The last CIS Senior Project group succeeded in creating a Log-In Tracking Application. However, Hurricane Ike interfered with the installation schedule, and the application was never installed. In fact, after Hurricane Ike, there was no longer a network at all.

All that was left of the previous network was a bundle of cables, routers and switches, no longer connected to any systems. We had to rebuild the network to continue our project.

After Before

Components Included in Network Two Modems Two Switches Two Routers One Proxy Server Eight Workstations Five Administration Systems

Putting Everything Together

Network Reassembled Now that we have a network... We can setup the proxy server.

Server Project

Business Needs The ability to register and track users. The ability to filter and block inappropriate web content.

Meeting Those Needs Design framework Multiple applications Force authentication Content filtering Modularity Flexibility Expandability

Technologies Involved Linux Apache Netfilter Squid MySQL PHP FreeRADIUS Perl Chillispot

Linux & Apache Ubuntu Linux serves as the core of the proxy server. It is upon Linux that the whole project is built. Apache is undoubtedly the most prominent web server in existence. Apache is responsible for serving the login application to the clients.

Chillispot & Perl Chillispot is a mesh technology that allows us to use FreeRADIUS and MySQL in conjunction to decide if a client should have access to the internet or continue being redirected to the login page. Perl is a scripting language that the actual gateway application itself is embedded in.

MySQL, PHP, FreeRADIUS MySQL is a world class enterprise level database application. MySQL stores all client information. PHP is a scripting language created for designing web pages. It is used to enter the information into the database. FreeRADIUS handles Authentication, Authorization and Accounting (AAA)

Squid & Netfilter Squid is the most widely used content filtering system in use today. Squid handles blocking inappropriate content. Netfilter, otherwise known as IPTables allows for us to DHCP all of our clients and for us to redirect traffic from port 80 to port 3128 to be filtered by Squid.

Workstation Project

What was done to Work Stations

All Computers were imaged using Acronis 2009

Created Bootable Disk
