Hell0!
Recently ,I have met a problem .I want to do a experiment using
madwifi. The topology is as foollows:
pc1 (192.168.0.1) )))) (((( mesh1(ap+br(192.168.0.2)+wds) ))) (((
mesh2(ap+br(192.168.0.3)+wds) )))) (((( pc2(192.168.0.6)
for PC1,I have done the folling commands:
wlanconfig ath0 create wlandev wifi0 wlanmode ap
brctl addbr br0
iwpriv ath0 mode 3
iwconfig ath0 essid test_1 channel 1
iwpriv ath0 wds 1
ifconfig ath0 up
brctl addif br0 ath0
ifconfig br0 192.168.0.2 up
wlanconfig ath1 create wlandev wifi0 wlanmode wds
iwpriv ath1 mode 1
iwconfig ath1 channel 6
iwpriv ath1 wds_add 0A:1D:0F:30:4B:04(peer_wds_mac)
iwpriv ath1 wds 1
ifconfig ath1 up
brctl addif br0 ath1
echo 1 > /proc/sys/net/ipv4/ip_forward # make sure, kernel
allowed to pass packets between interfaces.
For pc2:
wlanconfig ath0 create wlandev wifi0 wlanmode ap
brctl addbr br0
iwpriv ath0 mode 3
iwconfig ath0 essid test_2 channel 1
iwpriv ath0 wds 1
ifconfig ath0 192.168.0.3 up
brctl addif br0 ath0
ifconfig br0 up
wlanconfig ath1 create wlandev wifi0 wlanmode wds
iwpriv ath1 mode 1
iwconfig ath1 channel 6
iwpriv ath1 wds_add 0A:1D:0F:00:73:D3(peer_wds_mac)
iwpriv ath1 wds 1
ifconfig ath1 up
brctl addif br0 ath1
echo 1 > /proc/sys/net/ipv4/ip_forward # make sure, kernel
allowed to pass packets between interfaces.
Now,from pc1,I can ping 192.168.0.2 and 192.168.0.3 successfully.from
pc2,I can also ping 192.168.0.2 and 192.168.0.3 successfully.But pc1 and
pc2 can not ping successully with each other.Then I use wireshark to see
what is wrong.To my surprise,when I ping 192.168.0.1(the address of pc1)
from pc2,pc2 can learn the mac address of pc1,while when pc1 sending icmp
echo request ,the wireshark on the mesh1 can not seize the packet by ath1
and br0.but by ath0,it can sucessfully grasp the icmp echo request packet.
The information of mesh1 is :
