Thanx John
That will be of great help!! as of right now i am kind of lost in MIT
configuration and mine. I have enabled the roofnet by deleting SIMPLE
AUTHETICATION ENTRY from /tmp/runtime.click file. Also deleting line from
"/ROOFNETDIR/scripts/load_config.pl" which makes this file:
#my_system "cpp $defines $click_config | grep -v '\#' >
$click_config_runtime";
I enabled ROOFNET which gave me "srcr" interface. What exaclty is the
functionality of srcr and how it works , cud be a reasonable question to
ask? I am also writing my ifconfig after starting roofnet.
[root at localhost ap]# /etc/roofnet start
Starting roofnet: cardmgr[3677]: watching 1 socket

SYSTEM RUNNING !!HOTCONFIG
---------------------------------------------------------------------------------------------------
I am the ONE who added these extra lines in your "roofnet scripts" to test
it. My "ifconfig" is like this:
[root at localhost ap]# ifconfig srcr
srcr Link encap:Ethernet HWaddr 00:01:02:03:04:05
inet addr:5.35.253.45 Bcast:5.255.255.255 Mask:255.0.0.0

------------------------------------------------------------------------------------------------
Another question which is OF interest to me is CAN WE ASSIGN OUR OWN IP
ADDRESS TO SRCR and WLAN0 INTERFACE something like 10.1.2.X ??
--------------------------------------------------------------------------------------------------
"dmesg" gives me this :
click: starting router thread pid 3922 (df104260)
click_wifi: registering tx callback -526089764
Dead loop on virtual device wlan0, fix it urgently!
