IP Bandwidth Watchdog 0.8.1
IP Bandwidth Watchdog (ipband) is a pcap based IP traffic monitor.
This utility could be handy in a limited bandwidth WAN environment (frame relay, ISDN etc. circuits) to pinpoint offending traffic source if certain links become saturated to the point where legitimate packets start getting dropped.
It also can be used to monitor internet connection when specifying the range of local ip addresses (to avoid firing reports about non-local networks).
