I am having a problem running Airodump/crack/replay after running Kismet. Or vice versa.

If I run Kismet, then the air tools, then Kismet again, Kismet says its not in monitor mode (or still in monitor mode) and exits. What do I type to fix it so I can run Kismet again?

Does Kismet need to be in iwconfig eth1 mode monitor? If not, how do I make it "not" in monitor mode. What is the opposite?
