Hai, I am doing a final year project in networking and my project title is "Controlling IP Spoofing through Interdomain Packet Filters".I don't know how to send a packet to destination node through shortest root and also i want to place a IDPFfilter in intermediate node.Here i want to use a BGP protocol.So send me some source code under this condition.

Here are the steps to connect two PCs using a lan cable (crossover)--
1. Be sure that both computers are logged in to Windows. 2. Connect each end of the cat5 crossover cables in to the network cards of each computer. 3. Bootup both computers and sign them both on to Windows. 4. In order for both PC's to be able to communicate together, the Ethernet adapters will need to be configured with a static IP address and a common Subnet mask. As an example, assign one PC an IP address of 18.104.22.168 and assign the second PC an IP address of 22.214.171.124. Both machines should use the Subnet mask 255.255.255.0. Here's how to configure your Network Card: Go to Start>> Control Panel>> Network Connections>> Right click your Local Area Connection and select Properties. Scroll the list for the entry titled: Internet Protocol (TCP/IP). Click the entry and select Properties. Under the General tab, tick the box titled: Use the following IP address. Enter the IP address and Subnet mask that you would like to use. Repeat the steps above for the second computer system. 5. Be sure that both PC's have a common workgroup name of 15 characters or less. Here's how: Go to Start>> Control Panel>>System. Select the Computer Name tab. Click the Change button. Change the Workgroup name. Repeat these instructions on the second computer ensuring that both computers are named exactly the same. 6. Reboot both computer systems. 7. Next, open a command prompt on one of the computers by going to Start>>Run. Type in: command [Enter] or click OK. 8. Type: ping 126.96.36.199 (if you are using the computer assigned with 188.8.131.52) press Enter. 9. Five replies to your ping should be indicated. 10. Once you get the two computers to communicate successfully together, you can now enjoy the benefits of file sharing, printer sharing and Internet connection sharing.
I suggest the following: Install a packet analyzer to the target machine. This program helps you observe and analyze the network traffic real time. It is helpful for debug the network packets, look inside how the frames is structured. The Wireshark is quite popular debugger tool. Install it and check TCP/IP and SNMP packets with it. Here is it: http://www.wireshark.org/download.html
Second: There is a lot of information on the internet about the SNMP freame formats and TCP/IP protocol. Here are some useful links: http://www.tcpipguide.com/free/t_SNMPMessageFieldDefinitionsGeneralMessageFormatand.htm http://www.dpstele.com/layers/l2/snmp_l2_tut_part1.php http://www.rane.com/note161.html A lot of RFC documents write down the SNMP protocol.
