How can i know if there a sniffer running in my network?

On possibility is run ifconfig and see if the network interface is in promiscuous mode.

OTOH, there are several techniques for detecting sniffers remotely. The guys from atstake.com had a program that can be used for that.

Note, however, that's a heuristic detection.

For the "theory" behind these programs, use Google, there are many papers on this subject.
