Ettercap hangs while scanning for hosts

[michelinok]

Hi!
I hope this is the right forum...anyway here's my problem: when i try to scan for hosts with ettercap, it hangs at 100% (same if i use gtk or ncurses).
Any idea?

Download ettercap-common* & ettercap-gtk* .deb's

Remove installed files:

sudo apt-get remove --purge ettercap-gtk
sudo apt-get remove --purge ettercap-common

Then "dpkg -i" install the new downloaded .deb's from terminal. Example (for 32bit):

dpkg -i ettercap-common_0.7.3-1.4ubuntu1drizzt1_i386.deb ettercap-gtk_0.7.3-1.4ubuntu1drizzt1_i386.deb

hmm you doing something wrong check list

edited etter.conf file *
forward ip *
redirect ports *
sslstrip *

question have you tried the command way I recon when your using the gtk you havent select the hosts right something strange

ok do this forget all that for a second do this

ettercap -T -q -M ARP // //

take a snapshot of that terminal and post it dont worry about sslstrip or anthing else **** DONT USE etter-gtk use command

close ettercap terminal by pressing 'q' dont just close the window its very important

I bet I know whats wrong your not using 'q' and the causing dos and ettercap cant scan the network becuase it down

I am running BT5 on VMWare - I had uninstall ettercap-gtk and ettercap-common.
"dpkg -i" install the ubuntu1drizzt1_i386.deb version - now i can see the ettercap,
not before.

When I do>

sudo ettercap -T -q -i wlan1

Listening on wlan1... (Ethernet)

wlan1 -> 00:C0:CA:XX:XX:XX invalid invalid

Privileges dropped to UID 65534 GID 65534...

28 plugins
39 protocol dissectors
53 ports monitored
7587 mac vendor fingerprint
1698 tcp OS fingerprint
2183 known services

Starting Unified sniffing...


Text only Interface activated...
Hit 'h' for inline help

Then...nothing happen

When I close using the 'q' key, I get

iptables v1.4.4: can't initialize iptables table `nat': Permission denied (you must be root)
Perhaps iptables or your kernel needs to be upgraded.

Same thing if I use

ettercap -C --> Unified...--> scan for host


I would appreciated if I can get some help, ideas.....thanks

i love you dude lolllll i have been looking for a solution to this for a week now - literally tried everything.
but your solution worked for me like a charm - i am running BT5 KDE 32Bit - i might try it on 64bit and report back.
