[Click] for help on Roofnet

[欧阳鑫]

Hi everyone,
     We are running experiments with Roofnet on PCs. I have downloaded
click-1.8.0, and configured, make, make install it successfully. Then
I run: "./gen_config_roofnet.pl --dev wlan0 | click -" on TWO PCs. The
problem is, we cannot ping each other on the 2 PCs.  We do not have
the old Atheros wireless cards, but use the new Atheros wireless cards
(802.11n supported) drived by ath9k. I am not sure if this is ok.

"/sbin/ifconfig srcr" result on PC 1:
srcr      Link encap:UNSPEC  HWaddr

On PC 2:
srcr      Link encap:UNSPEC  HWaddr

          collisions:0 txqueuelen:500
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

The srcr interface's HWaddr is
00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00. Is this ok?

On PC1 and PC2, I ping the other host, no response.

On PC1, "./read_handler srcr/es.bcast_stats" shows

"./read_handler srcr/lt.routes":

200 Read handler 'srcr/lt.routes' OK

The questions are:
(1) Why as neighbors, PC1 and PC2 cannot ping each other?
(2) srcr/lt.routes shows no data, Is this OK?
(3) Each PC has 3 interfaces, srcr, rate and wlan0. Which one should
be used to do experiments (like COPE)?
