Of course you can detect a sniffer, but are you willing to pay the cost
of doing so?
You can't "detect a sniffer" from looking at the net; the only way you can
try is to identify specific software indications of one being run on your
machine. If it's run on a different machine, on one you can't check (perhaps
on a palmtop someone has plugged into the net), then you can't detect it at
all. Even if it's being run on your server, you can detect it if the author
of the sniffer didn't know about, and defeat, the particular detection
mechanism you use.
