Dave,

Appreciate any suggestions debugging the problem below. 

I finally flashed a build I made onto the router and it seems to boot fine and
is broadcasting the two SSIDs I programed into it but I cant ssh into the router, 
neither through wireless nor an ethernet cable. 

----------------xxxxxxxxx--------------------
$:OpenWireless ranga$ ssh root@172.30.42.1
ssh: connect to host 172.30.42.1 port 22: Connection refused
----------------xxxxxxxxxx-------------------

All ports except 53 seem to be blocked. Even the webserver 
we have running on 80/443 is not responding.

$:OpenWireless ranga$ nmap 172.30.42.1

I started with the etc directory in 3.10.40-6 and removed a few things
and made some changes in /etc/config. I kept the /etc/config/firewall
file unchanged. So I am not sure if it is the firewall blocking the ports.
Here is a link to the /etc I placed in cerowrt/files directory to have it 
compiled into the build.

Could it be that when building, the permissions with which
the files are being created in the firmware image are not what 
they need to be, and this is causing the problems I am seeing ?
Is there any way to analyze the firmware image without flashing
it onto a router ?

Thanks,
Ranga
