It would be easier to answer this question if I better understood the level 
you are asking it at.

The beginner-level answer to it is to use an application and associated 
library (e.g, tcpdump or ethereal, and libpcap) that supports setting 
promiscuous mode.

For the details of how to set it in a NIC driver, I'd suggest referring to 
the source for libpcap; my quick scan of it leads me to suggest checking 
the pcap_open_live() function call.

Of course, you need root access to do any of this.
