How to get Mac Id of my client machine

[ganesh pol]

i want to write one servlet which will give me MacID of my client from whom request came

2] also the IP Address Of client although it came through proxy server

help me it is urgent

[Darren Edwards]

Java has no native way to get a MAC address - you will have to write some native code for each platform. Then again it will probably be useless to you as a mac address changes as the packet moves through different network segments.

Proxy servers don't tell you the client IP.

It's not possible in a servlet - the HTTP request simply doesn't contain that information.

For a desktop app, you'll need to find a native API that returns that information, and access it through JNI, just like Darren mentioned.

So what part of it's not possible is confusing you?

The only way to do this is to run an agent program on the client that can use JNI to get the information and communicate it to the server. There is no way to do this with servlets or HTTP.

Since this is a servlets forum, it is not the right place to post JNI questions.

But, if you don't know who the client is, how are you going to get him to install your program on his system?

I'm going to close this topic as this is not a Servlets issue.

I suggest you post a question in another forum. You will not be able to do this without being able to install a program on the client computer.
