[Click] Where can I get a correct gen_config_roofnet.sh?

 Hi,

 I'm not sure if this question probably had to be put on Roofnet
 mailing list, but it is about the file included in the click.

 I'm using the latest releases of roofnet, click and madwifi-ng.
 I have barely installed all three packages on FC4 (linux-2.6.16.13).
 Actually, it took unnecessarily too much time mainly due to out-of-date 
 wiki installation guide of Roofnet.
 I also have validated if the installed click is properly working
 using simple examples (KernelTun, etc). Seems ok.

 Then, I found the file gen_config_roofnet.sh at CLICKDIR/conf/wifi/
 may be buggy or incomplete.
 A ping between two roofnet nodes does not work out
 although I adjusted the file for kernel mode click according to my 
 network interface setup (e.g. ath3 -> ath0, comment out some setups
 that had been already made like ifconfig ath0 up).
 I tested the ping using either ath0's ip addr or srcr1's ip addr.
 Neither works (simply no response with each other).

 I believe I correctly set up all required parameters related to wireless 
 interface such as channel number (freq), ssid, mode, etc as follows.
 I also had installed ath_pci using:  "modprobe ath_pci autocreate=adhoc".

ifconfig ath0
===============================================================
ath0      Link encap:Ethernet  HWaddr 00:09:5B:93:0B:14  
          inet addr:10.1.1.2  Bcast:10.1.255.255  Mask:255.255.0.0
          inet6 addr: fe80::209:5bff:fe93:b14/64 Scope:Link

          RX bytes:0 (0.0 b)  TX bytes:1476 (1.4 KiB)

c.f.)  Another machine has simply a different IP address of 10.1.1.3.

ifconfig srcr1

================================================================
c.f.) Since I'm using Emulab wireless nodes, the default router 
should not be changed as above.

 Any tip or comment would be greatly appreciated.

 Thanks,
