The primary aim of the Gtk+2 panel project is to provide a panel that reuses whatever is available (if it is not overkill) in the obvious way, such as subclassing GtkWidget instead of implementing applets, or by using a GtkBuilder file instead of defining a new format to customize the panel. This approach gives some additional advantages for free: you can use common tools in uncommon ways. Above all, you can use Glade to design your own panel. All the dependencies apart from GTK+ are (and hopefully will be) optional.
Jenny is a packet generator, injector, editor, and browser for network and penetration testing. You can use Jenny to produce and manipulate network traffic (such as packets and frames), to browse pcap files and edit them, and to inject or save your changes as a new pcap file. It works only in GUI mode, and must be run as root.
