Ettercap mengalami banyak bug pada backtrack 5 R1. Kali ini bug memunculkan pesan error:
ip_forwarding was disabled, but we cannot re-enable it now.
remember to re-enable it manually
Bagaimana cara mengatasinya?
1. Buka terminal, lalu masukan perintah:
Command:
root@revolution:/# nano /usr/local/etc/etter.conf
Maka anda akan melihat tampilan seperti ini:
######################################################################### ## ettercap -- etter.conf -- configuration file ## ## Copyright (C) ALoR & NaGA ## ## This program is free software; you can redistribut it and/or moify ## it under the terms of the GNU General Public Licese as publishedby ## the Free Software Foundation; either version 2 o the License, or ## (at your option) any later version. ## ## $Id: etter.conf,v 1.79 2005/07/07 10:08:55 alr Exp $ ## #########################################################################
Carilah baris seperti ini:
###################################### redir_command_on/off###################################### you must provide a valid script for your operating system in order to have# the SSL dissection available# note that the cleanup script is executed without enough privileges (because# they are dropped on startup). so you have to either: provide a setuid program# or set the ec_uid to 0, in order to be sure the cleanup script will be# executed properly# NOTE: this script is executed with an execve(), so you can't use pipes or# output redirection as if you were in a shell.

Cari baris:
# if you use iptables:
Maka anda akan mendapati pengaturan seperti ini:
# if you use iptables: #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"
2. Mengubah parameter redir_command_on dan redir_command_off
Hilangkan tanda pagar sebelum redir_command_on dan redir_command_off
Sehingga pengaturannya menjadi seperti ini:
###################################### redir_command_on/off###################################### you must provide a valid script for your operating system in order to have# the SSL dissection available# note that the cleanup script is executed without enough privileges (because# they are dropped on startup). so you have to either: provide a setuid program# or set the ec_uid to 0, in order to be sure the cleanup script will be# executed properly# NOTE: this script is executed with an execve(), so you can't use pipes or# output redirection as if you were in a shell.

Tekan ctrl+x untuk keluar dari konsol nano. Tekan y untuk menyimpan. Tekan enter untuk menyimpan meng-overwrite file lama.
Kemudian jalankan kembali ettercap:
Command:
root@revolution:/# ettercap -T -q -i wlan0
Perfect as usual
