ettercapmultipurpose sniffer/content filter for man in the middle attacks -
ettercap-graphical pkexec-based launcher for ettercap This launcher depends on policykit-1 and the menu packages, and basically wraps the ettercap binary command with a pkexec action script usually defined on /usr/share/polkit-1/actions/org.pkexec.ettercap.policy, allowing users to directly call ettercap from the desktop or menu launcher with root privileges. The commands available are exactly the same as the ettercap man page. Please refer to man ettercap for the list of available parameters. (don't forget to change "ettercap" to "ettercap-pkexec" as caller program). example: ettercap-pkexec -G will start ettercap with root privileges and the GTK2 interface.pkexec -

evmsThe evms command starts the Enterprise Volume Management System (EVMS) Command Line Interpreter (CLI). These command line options control where the EVMS CLI gets commands from and how it interprets those commands. This document begins by explaining the parameter option descriptions and then goes on to explain the commands that can be entered at the CLI's prompt. -
