I am looking for a tool that can check if a node's NIC can be set to promiscuous mode, so that i can conclude this node is
worthy of voice monitoring.

Any help is appreciated,

Thanks in advance

You could check the vendor website. Documentation, etc...

Not a tool, but here's a list of adapters that do.

It's actually a list of adapters that are supported for WinPcap ( which requires the adapter to work in promiscuous mode.

Yes, i crossed these paths before. The list of adapters as you know is not 100%. I have come across situations at the client site where
the adapter is not listed. In order to give a quick answer without installing Ethreal/Winpcap setting up SPAN and analyzing the packets physically before concluding, i would like to be able to have the ability to run a tool of some sort and verify if the packets can be monitored.

Probably your fastest fix is to hit the NIC vendor and get the specs there...  A single app. to probe your NIC would be pretty tough to keep up with (from a support standpoint), as there's new NICs/versions of NICs coming out weekly...

Good Luck,
