Configuration : -

Active Directory was configured on a Windows 2003 Server (Machine Name - Galileo). The machine was also configured as the DNS. The machine was made the Domain Controller with the following details:

The Domain Name- dcsl

FQDN dcsl.uhcl.edu

The Domain controller was made the first domain controller of the domain and a new forest was established.

Testing : -

A Windows 2000 Server machine(Machine Name - Alpha) was configured as the client/workstation in the dcsl domain.

An Active Directory user testuser was created on the DC(Domain Controller).

Using the testuser account from Alpha, the Active Directory configuration was verified.

Configuration : -

Linux Red Hat 9.0 was installed on a machine (Machine Name Einstein). The machine is dual homed and ip_forwarding enabled between the two interfaces. The interfaces were configured to two different Class C networks (192.168.100.0 and 192.168.200.0). The IP of the interfaceses :

Eth0 ? 192.168.100.1

Eth1 ? 192.168.200.1

The eth0 was connected to the hub. The DC (Galileo) was also connected to the hub. The DC was assigned the IP ? 192.168.100.2

A cross cable was connected between the eth1 of Einstein and Alpha. Alpha was assigned the IP ? 192.168.200.1

Testing :-

The connectivity between the Alpha and the eth1 of the Einstein was tested by pinging (ping 192.168.200.1) from Alpha.

The connectivity between the Galileo and the eth0 of the Einstein was tested by pinging (ping 192.168.100.1) from Galileo.

The ip_forwarding on the Einstein was tested by pinging (ping 192.168.100.2) from Alpha which was on network 192.168.200.0 with IP ? 192.168.200.2.

Configuration :-

The Microsoft Windows Server 2003 operating system has integrated VPN technology that helps provide secure, low-cost remote access and branch office connectivity over the Internet. The VPN Server was integrated with the Active Directory on   Galileo

Testing :-

• The default VPN Client on Windows 2000 Server was used for the VPN testing.

• The  ?testuser? on the Active Directory of the was given ?Dial-in? access.

• Using the account ?testuser? from the VPN Client on Alpha, the VPN tunnel to the VPN Server Galileo was established.

• To verify the connectivity, a home directory was created for the user ?testuser? on Galileo. On logon the home directory was configured to be mapped to ?M? drive on the client machine.

• On logging to the domain from Alpha using the VPN Client, the drive was mapped. This confirmed the establishment of a VPN tunnel.

Configuration :-

The Microsoft IAS server is configured to listen at default Authentication (1812)and Logging ports(1813).  The IAS server is registered to communicate with the Active Directory for Authentication information. The VPN Server on the Galileo was made the AAA Client and was configured to obtain the Authorization and Authentication information from the AAA Server.

Testing :-

• The default VPN Client on Windows 2000 Server was used for the VPN testing.

• The  ?testuser? on the Active Directory of the was given ?Dial-in? access.

• Using the account ?testuser? from the VPN Client on Alpha, the VPN tunnel to the VPN Server Galileo was established. The AAA mmc showed the VPN Client.

• To verify the connectivity, a home directory was created for the user ?testuser? on Galileo. On logon the home directory was configured to be mapped to ?M? drive on the client machine.

• On logging to the domain from Alpha using the VPN Client, the drive was mapped. This confirmed the establishment of a VPN tunnel.

Configuration  :-

Installed Linux 9.0 on Alpha and made it dual boot

Installed OpenSource?s PPTP client for VPN. Configured the PPTP client to talk to the Microsoft VPN server running on Galileo. Established a VPN tunnel from the Linux on Alpha to the Microsoft VPN server on Galileo. Tested the tunnel by pinging Galileo through the VPN tunnel.

Installation Steps for PPTP Client

1.      install MPPE support in your kernel, (if required)

2.      install MPPE support in PPP, (if required)

3.      install the PPTP client,

4.      configure the client,

5.      start the tunnel, and

6.          configure routing.

 Testing:

 When the PPTP client is configured to talk to the VPN server creating a VPN tunnel, it creates a virtual Network PPP Interface over the existing Ethernet NIC.

The testing is done by directing the ?PING? request through the ?PPPO? interface created by the PPTP tool as:

# ping ?i ppp0 192.168.100.2(Galileo).
