ORBIT-USER: Virtual access point doesn't work, anyone help?

[Kishore Ramachandran]

Hi Bin:

Two reasons I see why your configuration does not work:

(a) When you run nodehandler, it will reload the driver and wipe out your
config.

So, your sequence of commands:

>    1) imageNodes 1,1..2 baseline-2.0.ndz
>    (for some reason, I have to run more than once)
>     2)  wget -O - 'http://cmc:5012/cmc/on?x=1&y=1'
>        wget -O - 'http://cmc:5012/cmc/on?x=1&y=2'
>     3) ./config_commands.bash (which config node1 and 2)
>     4) nodehandler helloworld

The effect of step 3 gets wiped out in step 4. Also, nodehandler does not
know how to deal with madwifi-ng driver.  My suggestion would be to stick to
bash and start your traffic generator there (you can use
iperf,netperf/nuttcp/etc.).

(b) IP assignment issue
>From your config-*.bash script, you put the client on 192.168.1 network

"ssh root at node1-1 ifconfig $i 192.168.1.$Number"

and you put the AP on 192.168.2 network

"ssh root at node1-2 ifconfig $i 192.168.2.$Number"

Thats why ping does not work - they are not on the same IP network. This can
be fixed as follows:

"ssh root at node1-1 ifconfig $i 192.168.1.$Number netmask 255.255.0.0"
"ssh root at node1-2 ifconfig $i 192.168.2.$Number netmask 255.255.0.0"

OR

"ssh root at node1-1 ifconfig $i 192.168.1.$Number"
"ssh root at node1-2 ifconfig $i 192.168.1.$Number"

regards,
Kishore
