Description David Woodhouse 2007-11-03 10:57:54 EDT
Until recently I could do this:
 echo -n moni0 > /sys/class/ieee80211/phy*/add_iface
 iwconfig moni0 mode monitor
 ip link set moni0 up
 tcpdump -i moni0 -l -n

It doesn't work in Fedora 8 though -- what replaces it?
Comment 1 John W. Linville 2007-11-21 16:48:04 EST
Those bits were removed upstream in order to reduce the sysfs user interface 
commitment.  It may or may not come back there.

The netlink-based tool that give this functionality is here:


We probably need to get that packaged for F9.  But for now it doesn't do 
much...except add and remove interfaces... :-)

In the meantime, I'll add a patch to restore the sysfs bits in F8.  Please 
test when it is available.  Does that work for you?
