Hi, I want to use mac80211_hwsim (from kernel 2.6.30-rc6) for some testing, but I can't get the two interfaces to communicate with each other. I've done the following: # hostapd -B hostapd.conf Configuration file: hostapd.conf Using interface wlan0 with hwaddr 02:00:00:00:00:00 and ssid 'mac80211 test' # iwconfig wlan1 essid "mac80211 test" # ifconfig wlan0 10.0.0.1 up # ifconfig wlan1 10.0.0.2 up wlan1 can successfully associate, but I can't reach any interface via the other: # ping -I wlan0 10.0.0.2 PING 10.0.0.2 (10.0.0.2) from 10.0.0.1 wlan0: 56(84) bytes of data. >From 10.0.0.1 icmp_seq=1 Destination Host Unreachable # ping -I wlan1 10.0.0.1 PING 10.0.0.1 (10.0.0.1) from 10.0.0.2 wlan1: 56(84) bytes of data. >From 10.0.0.2 icmp_seq=1 Destination Host Unreachable With tcpdump I can see ARP requests on both interfaces: 09:43:28.687273 ARP, Request who-has 10.0.0.2 tell 10.0.0.1, length 28 But there is no answer or other traffic. Did I forget soemthing in the setup? Thanks for your help.
