    Question ettercap crashes when scanning for hosts

    Hello, when I launch the ettercap GUI from the menu or from the terminal with this command i get an error:

    Code:
    :~$ sudo ettercap -G
    
    ettercap NG-0.7.3 copyright 2001-2004 ALoR & NaGA
    
    Dissector "dns" not supported (etter.conf line 70)
    Ooops ! This shouldn't happen...
    Segmentation Fault...
    But the GUI starts. Then i do 'Start Unified Sniffing' and after that I try to scan for hosts. The moment I select 'scan for hosts' from the menu. Ettercap just quits.

    Can anyone help me with this ? Please ?

    Re: ettercap crashes when scanning for hosts

    Ettercap is an older program that hasn't been updated in around...4 years, so there may some issues. If you don't see it resolved here you could try the ettercap forums (which haven't had a post in around a month) or simply e-mailing the original developers directly.

    I should preface this by saying that I am not really sure if I can solve your problem but what happens if you scan for hosts first then do unified sniffing?

    Cheers.

    Questions pertaining to "stealthed" ports kind of make me LOL IRL

    Thanks for your reply. I cannot scan for hosts. I have to start unified sniffing first before the menu 'hosts' appears.

    I have this problem, the only thing I can see atm is there isn't and etter.conf file so I'm doing some more digging.

    you need to specify the interface in the etter.conf file, you could also try;
    ettercap -i [interface] -C
    Thats how I run it works for me.

    Problem solved: https://launchpad.net/~timothy-redaelli/+archive/ppa

    Uninstall your current ettercap version and download and install the recompiled .debs from above (I think you will only need ettercap-common and ettercap-gui not the other one). Also, if you are running it from terminal don't forget to run it as super user - "sudo ettercap -G"

    The solution that Hilko gave seems to have fixed the problem for me. At least, no segfault when scanning for hosts.
