    Default Ettercap -G MITM not showing anything

    Hi everyone,

    I'm having troubles using ettercap to do an MITM in my own network.
    I deployed a switch, connecting my victim pc, my atatcker pc, and the router(default gateway)

    When I start ettercap using comand:
    ettercap -G
    sometimes, when I scaning the hosts I get this error:
    (<unknown>:6026): Gtk-WARNING **: Invalid text buffer iterator: either the iterator is uninitialized, or the characters/pixbufs/widgets in the buffer have been modified since the iterator was created.
    You must use marks, character numbers, or line numbers to preserve a position across buffer modifications.
    You can apply tags and insert marks without invalidating your iterators,
    but any mutation that affects 'indexable' buffer contents (contents that can be referred to by character offset)
    will invalidate all outstanding iterators
    But sometimes, it fails and give after the previous warning this:
    Ooops ! This shouldn't happen...
    Segmentation Fault...
    Please recompile in debug mode, reproduce the bug and send a bugreport
    anyway, sometimes I can scan, and I get the host list.

    -I add victim to target 1, and the default gateway to target 2.

    - I go to MITM and chosoe arp posoning. Now, here I already tryed all types of combinations.
    - I press ok
    - I go start, and press start sniffing.

    The problem is that nothing appear as output when I do something in victim machine.
    This is my output:

    SSL dissection needs a valid 'redir_command_on' script in the etter.conf file
    Privileges dropped to UID 65534 GID 65534...
      28 plugins
      40 protocol dissectors
      55 ports monitored
    7587 mac vendor fingerprint
    1766 tcp OS fingerprint
    2183 known services
    Randomizing 255 hosts for scanning...
    Scanning the whole netmask for 255 hosts...
    5 hosts added to the hosts list...
    Host added to TARGET1
    Host added to TARGET2
    ARP poisoning victims:
     GROUP 1 : 48:5B:39:82:9B:AA
     GROUP 2 : 58:98:35:91:89:66
    Starting Unified sniffing...
    Can anyone help me with this??
    Thanks in advance.

    Ok, I resolved the issue of the error, updating it to version 0.7.5.
    But still can't get any info when sniffing. Any help?
