Yes, look at this paper:
Detection of Promiscuous Nodes Using ARP Packets

This is working
Antisniff is a cool tool that exploits certain 'features' inherent in some
TCP/IP stack implementations to detect the supposedly passive activity of
sniffing. However, do keep in mind that if these features have been
corrected or a custom TCP/IP stack is used, you will not be able to detect
How would you go about detecting what NIC's are in promiscuous mode? Is
there some sort of mass ping to find such a thing out?

Though not perfectly possible you might want to check out this article:

I too would love to know what other means of detecting sniffers exist. The
main problem is most sniffers are passive and detecting them is hence
If you are on the same sub-net the only way would be to find out who has there NIC in
promiscous mode. If its out on the web AFAIK its not possible.
Sniffing is a passive attack and is very hard to detect. If you are worred about
someone sniffing you passwords the i would recomend implementing

check out this site. this guy has lots of info on sniffers, and detection.

to detect commercial sniffers you can send traffic to a known non existent
ip address, and most commercial sniffers (snoffer pro, ether peek, etc) will

If you're a domain admin on a purely NT/2K
network, detecting sniffers isn't all that hard.
Fo to http://patriot.net/~carvdawg/perl.html and
