check out this site. this guy has lots of info on sniffers, and detection.
http://www.robertgraham.com/pubs/sniffing-faq.html 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 attempt to resolve that address. watch for requests to your DNS for that address. forgive me if this was posted wrong, it's my first post to the list.
