The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Raw IP packets -- Send/Receive

Asked by calius in Windows NT Networking

Tags: ip, raw, send, packet, receive

Hi all

I need to send and receive RAW IP packets on a Win2K/XP box. That is: I want a specific process in the system (which I write, of course) to have a different IP than that of the computer's. This process will be sending RAW IP packets, and will receive packets directed to "it's" IP address.

How do I go about this?

I thought about some fiddling with RAS, creating a "dial connection" to a PPP server which will give me my IP, but for that I need a programmable PPP client linked in my process. Does anyone know of such a thing?

I've also thought about adding another "virtual" interface onto my ethernet card, with a different IP, use it only from this process, and then opening a RAW-IP-mode winsock socket on that interface and IP. However, is this allowed? What about ARP on other machines in the network? How do I do this, anyhow? How do I *receive* packets, before windows "Eats" them?

I understand this is a hard one, and calls for real Gurus, so I've graded it accordingly...
