This is a GTK based packet analyzer. Its abilities as a sniffer or scanner are limited, but this sniffer is much easier to use than other popular sniffers such as tcpdump. In addition, there is a protocol definition file in which other protocols can be added. . Karpski may also be used to launch programs against addresses on your local network and as a local network intrusion tool. . For more information: http://mojo.calyx.net/~btx/karpski.html
