promiscuous mode

I am trying to figure out how to set my Network card to promiscuous mode.
I am running Windows ME.

Is that a techinical term 'promiscuous mode'?

Does the network card support 'promiscuous mode'? And yes it is a technical term. :)

Promiscuous mode is a state in which a network adapter card copies all the frames that pass over the network to a local buffer, regardless of the destination address. This mode enables Network Monitor to capture and display all network traffic.

You will need a device driver to support P mode, there is libpcap for *nix and win32, not sure if there is a version available for ME yet.

My computer is set to.. promiscuous mode.. Unfortunately.. it can't keep its cord out of my commodores port.. hmm.. it's in promiscuous sex mode.. now I got it.. and.. I suppose it's got some jungle fever.. I saw it going for the VCR..

talk about hard-drive....:umph:

uhh ok......

Are you just trying to set up your NIC in Promiscuous mode, or are you trying to get a sniffer to work? Just setting in up in promiscuous mode won't get you anywhere if you don't have software to interpret and capture the packets.

Try NATAS if you want a lightweight easy sniffer for Win and the winpcap packet capturing driver if your nic supports it.

I am going to code my own sniffer. I just need to know if there is a manual way to turn promiscuous mode on, or if I can code it in my program.

run linux?

I know that in Windows NT there was a registry key you could turn on to enable promiscous mode for the Network Monitor...
I don't think that needed any special hardware to run, but all you could see were the transfer statistics, you couldn't actually read the data inside the individual packet...

What OS are you coding for?

YOu shouldn't have a problem with it, But if you want better advice I suggest you be more specific, Curious what language ?

I feel that if you want to develop a Sniffer before you even think about coding you will have to gain a good conceptual understanding of how the lower levels of the Systems work, and at what level you wish to intercept the traffic I.E. after the NDIS Before IP etc.

You don’t need to have the NIC in promiscuous mode to sniff packets, however I would recommend getting hold of an open source analyzer and having a play. I believe there are some out there.

The next problem is what are you going to do with the packets once you have captured them, are you going to decode the protocols and so on.

What you are proposing in not a straightforward task and there are many very capable analyzers available.
