Default Setting a nic to promiscuous mode?

I am running OpenBSD 4.3, I would like to set my secound NIC to promiscuous for monitoring reasons and suggestions?

The pcap(3) library may be useful to you, it's in base, also.. tcpdump(8) sets the PROMISC flag on the appropriate interface, the version of tcpdump in base was audited by the OpenBSD developers though.

Snort 2.8.0.1 is in packages, and is lots of fun. BASE is a web front-end that makes it even more fun.

Unless you are constructing your own tools, other tools such as tcpdump(8) or nmap do this automatically. Unless you have other reasons, perhaps it is worth looking through what third-party applications are already available in packages & ports. The following third-party site tracks what OpenBSD has available:

My objective is to just set my NIC into promiscuous mode so for any program I use I will have that stetting, I dont even know if that's possible. If it isnt I will be needing a way to set it in that mode in C so my program I am writing will work right.
