Ettercap is a nice tool but I don't run X on my Gateway/Servers. > > Neither do I. :-) Now I know ettercap has a GUI... I've just checked the http://ettercap.sf.net/ website and - gladly - the GUI isn't the only interface option. From the website: "Running Ettercap: You need to select a user interface (no default) using -T for Text only, -C for the Ncurses based GUI, or -G for the nice GTK2 interface." Building it the way you want: ----------------------------------------------- # cd /usr/ports/net-mgmt/ettercap # make You may use the following build option(s): WITHOUT_GTK=yes builds without GTK2+ GUI WITHOUT_ICONV=yes builds without support for UTF-8 WITHOUT_PCRE=yes builds without support for perl regexps in filters WITHOUT_PLUGINS=yes builds without ettercap plugins WITHOUT_SSL=yes builds without support for SSH1 and SSL decryption ----------------------------------------------- Good packet hunting, Alex
