System: NetBSD discovery.invisible.ca 3.99.9 NetBSD 3.99.9 (DISCOVERY) #26: Thu Sep 29 18:49:43 ADT 2005 jmcneill@discovery.invisible.ca:/usr/obj/sys/arch/i386/compile/DISCOVERY i386
Architecture: i386
Machine: i386
>Description:
I have an application that attempts to read from a tap device, and
tunnel 802.11 packets over IP. Unfortunately, 802.11 beacons aren't
passed to the tap device, so I can't replicate the wireless packets
on the other side.
>How-To-Repeat:
ifconfig bridge0 create
ifconfig tap0 create
ifconfig tap0 up
brconfig bridge0 add "${WINTF}"
brconfig bridge0 add tap0
brconfig bridge0 -learn "${WINTF}"
brconfig bridge0 discover "${WINTF}"
brconfig bridge0 -learn tap0
brconfig bridge0 discover tap0
brconfig bridge0 flush
brconfig bridge0 up
Then attempt to read from /dev/tap0, notice that you won't see any
802.11 beacons.
>Fix:
Not sure yet.
