BPF based visual packet rate monitor
While tcpdump shows what packets are going through the network, bpfmon will show how much in terms of bytes per second and packets per second in a nice pseudo-graphical terminal interface.
bpfmon also supports monitoring an iptables rule that is selected by command line option or selected from a menu (only under Linux).
bpfmon is licensed GPL-2.0+
Many Linux distributions already include this program under the name bpfmon.
