    Default Installing Ettercap-0.5.7.3 (Acer Aspire S3 Ultrabook)

    Hi, This is my first post iv just joined the BT foum

    Installing Ettercap
    (Linux Backtrack 5R3 gnome)
    I know there are a lot of install guides for this out there and a lot of this ground will have been covered in other posts, I would like to share how this worked for me. As you already know ettercap is installed ready to go when backtrack is used. I chose to dedicate and unused laptop to backtrack therefore installing this to the hard drive. From the beginning I have suffered from one of the bugs that many face. After scanning for hosts the session closes. Here is how I worked around this and the errors I encountered on the way. With backtrack being a clean new install I installed and configured a few things which I will document along the way. This may or may not have had something to do with the functionality in the end.

    NIC Configuration
    I started by configuring my NIC’s so I could disable the on board wireless card to prevent chances of conflict with my USB Alfa Networks AWUS036H.

    (nano /etc/network/interfaces)

    My on board wireless card was identified as Wlan0, I comment this out so this would no longer be seen by the system (# to comment out) Ctrl + X to save and Y to exit, I then run the following to restart the network (/etc/init.d/networking restart). Once the network had restart I used ifconfig to verify I could only see my loopback interface and Wlan1 (Alfa card)

    SPM Install
    After configuring the NIC I chose to Install Synaptic Packet Manager (apt-get install synaptic) which allowed me to completely uninstall Ettercap form the system. I removed all possible packages so this was no longer visible in the menu.

    System Update
    When the install of SPM was complete I updated the system running (sudo apt-get update) followed by (sudo apt-get dist upgrade) – This can take a long time.

    Libpango and libgtk
    Next came the install of these two components. Instead of installing them both together I installed them one by one

    (apt-get install libpango1.0-dev –fix-missing)

    I ran this with the fix missing extension as the first attempt was unable to fetch some archives. This gave me a successful install.

    (apt-get install libgtk2.0-dev)

    When installing this I was faced with the error

    “The following packages have unmet dependencies:

    Libgtk2.0-dev: Depends: libgtk2.0-0 (=2.20 1-0 0unbuntu2.1 is to be installed
    Depends: libxi-dev (>= 1:1.0.1-4) but is not going to be installed
    Broken packages


    To resolve this I carried out the following.
    I checked my repositories (cat /etc/apt/sources.list)

    I had the standard backtrack repos

    deb http://all.repository.backtrack-linux.org revolution main microverse non-free testing
    deb http://64.repository.backtrack-linux.org revolution main microverse non-free testing
    #deb http://source.repository.backtrack-linux.org revolution main microverse non-free testing
    deb http://updates.repository.backtrack-linux.org revolution main microverse non-free testing

    I added the following repositories by editing the source list

    (nano/etc/apt/sources.list)

    deb http://archive.ubuntu.com/ubuntu/ gutsy-updates main restricted universe multiverse
    deb-src http://archive.ubuntu.com/ubuntu/ gutsy-updates main restricted universe multiverse
    http://packages.ubuntu.com/search?su...ibpango1.0-dev

    Ctrl + X followed by Y to return to the terminal and save the repos.

    (apt-get update) to update the packages

    Finally (apt-get install libgtk2.0-dev)

    Libent 1.1.2.1 & Ettercap
    I downloaded Libnet from the following site http://linux.softpedia.com/progDownl...oad-10275.html and placed the libnet-1.1.2.1.tar.gz in the root folder

    I then went on to extract the file to the directory (tar -zxvpf /root/libnet-1.1.2.1.tar.gz)
    Then I went on to compile the install

    (cd /root/libnet)
    root@bt:~/libnet# ./configure
    root@bt:~/libnet# make
    root@bt:~/libnet# make install

    I downloaded the latest ettercap from the ettercap website currently ettercap-0.7.5.3.tar.gz and saved this to my root directory.

    Next I extracted ettercap (tar -zxvpf /root/ettercap-0.7.5.3.tar.gz)
    Then went to compile the install “advised by the latest version”

    (cd /root/ettercap-0.7.5.3)
    root@bt:~/ettercap# mkdir build
    root@bt:~/ettercap# cd build
    root@bt:~/ettercap# apt-get install cmake
    root@bt:~/ettercap# cmake ../
    root@bt:~/ettercap# make
    root@bt:~/ettercap# make install

    Ettercap now works every time.


    Hope this provides some use. I understand different people will experience different issues, I just thought I’d share mine


    Cheers

    Thanks mate. Nice text formatting too
    Everyone has started from ZERO. I'm not an exception but I'm trying to hear more than speak too much.

    Hi, Can i have help I'm blocked during Cmakefiles and...
    No I am kidding (Complaining at the first post...), because you explain well how to install Ettercap. I had problem with ettercap 7.4 so I install ettercap 7.5.3, and

    I found some trouble following your guide. But I've resolved it i have had some problem with : Gems who are according the AV a trojan ( answer disabled FireWall) and many problem with CmakeFiles :
    1) Impossible to load files with Cmakefiles
    Answer : I've made many manipulation; upgrade, update of Cmakefiles and libpango, libnet, python, : don't be afraid to update the packages


    2)The CMakeFiles says after upgrade :

    CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
    Please set them or make sure they are set and tested correctly in the CMake files:
    HAVE_PCRE
    linked by target "sslstrip" in directory /root/ettercap-0.7.5.3/plugins


    So i look in this forum, and I've found osirium and chaps about the HAVE_PCRE :
    http://www.backtrack-linux.org/forum...ight=HAVE_PCRE
    Follow the lines and after download PCRE (address in the topic below), and change the following... Allelluia : ettercap don't crash. (after 4 hours of research)
    GJ Bluesman and thank a lot
