ettercap - LAN Sniff

Hi, i am new to BT :) I tried to use ettercap but i think it doesn't work: i have a LAN with 3 PC: the first is a server where a created a login page, the second is the client and the third is yìthe attacker pc. When i execute these commands

echo "1" > /proc/sys/net/ipv4/ip_forward and ettercap -T -q -i wlan0 -M ARP /192.168.1.1/ /192.168.1.2/

,where 192.168.1.1 is the router IP and 192.168.1.2 is the victim IP, i don't get any error, but it seems that nothing happens while the victim pc is connecting to the server login page.
The only thing that i can sniff is when the victim pc connects to the router page (192.168.1.1) and enter the user and the password (admin-admin).

Where is the problem? It's something with ettercap or BT or with the server and login page?

why don't you put the fake page in your system and spoof the victim into it ? ..better to u .. on the other hand .. if you want to do as you are doing .. try to put the victim ip before the router ip
if not solved >>> try to explain your problem more

Off the top of my head, I believe that running Ettercap sets ip_forward to 0. I believe this is in the man page.

But for the simple task that you are trying to accomplish, I don't believe setting ip_forward is necessary.

If you want to see the traffic passing through the gateway, you must specify "arp:REMOTE" - again, this is in the man page.. might be worth the 3 minutes to read it.

I tried with ettercap GTK using arp remote but nothing changes...

Where is the problem? :confused:
