Ettercap is one of the most famous MITM applications ever. Installing it on Mac OS X was not entirely straight forward so here are some additional tricks I had to do to get it installed on Mountain Lion.

First off, I am using Homebrew, a package manger for OS X. Frankly, I sort of wish I had used MacPorts at this point, because it is more popular and there’s more documentation about using it. I’m not sure what the ramifications would be if I tried to switch at this point so I’m just going to plow forward using it.

I already had some of the needed dependencies required by Ettercap, so I’m going to focus on the problems I personally ran into. You may need to install additional libraries if you don’t already have them.

To enable PDF documentation generation – ghostscript (ps2pdf13) – groff $ brew install ghostscript To enable plugins: – libltdl (part of libtool) I didn’t run into a problem here To have perl regexp in the filters: – libpcre $ brew install pcre To support SSH and SSL decryption: – openssl 0.9.7 $ brew install openssl For the cursed GUI: – ncurses >= 5.3 I already had this because I installed kismet but you might need it For the GTK+ GUI: – Glib >= 2.2.2 – Gtk+ >= 2.2.2 – Atk >= 1.2.4 – Pango >= 1.2.3 $ brew install gtk+ For the SSLStrip plugin – Curl >= 7.26.0 This was a bugaboo. First do $ brew install curl This will install the recent version of curl that you need for ettercap. Unfortunately it will not symlink it to /usr/local because OS X already has a version of curl installed and brew doesn’t want to interfere with that. This sucks for us. We’ll need to modify the make file to point to our brew-installed version of curl. Go into the build directory you made while setting up ettercap and edit the CMakeCache.txt file to look like this: CURL_INCLUDE_DIR:PATH=/usr/local/opt/curl/include CURL_LIBRARY:FILEPATH=/usr/local/opt/curl/lib/libcurl. Software Crack Puzzle Quest 2 there. dylib That will get the installer to look in the right place for the updated curl files.

Finally, after you successfully build ettercap (using sudo make install), you need to modify a mac system plist file to allow for IP forwarding. You would know this if you read the README.OSXLION file included with ettercap. $ sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist replace with net.inet.ip.scopedroute=0 and reboot!

I installed the latest version last night on 10.8.3, it's pretty straight forward. Download the code, then read the README, it'll tell you all the dependencies. I used Macports to install all the dependencies, as it does it just fine and is easier to maintain.
