ipband is a pcap-based traffic monitor. It tallies per-subnet traffic and bandwidth usage and starts detailed logging if the specified threshold for a specific subnet is exceeded. This utility could be handy in a limited bandwidth WAN environment (frame relay, ISDN, etc.) to pinpoint offending traffic sources if certain links become saturated to the point where legitimate packets start getting dropped.

The integer type was changed to hold a cumulative byte count from long to double to avoid counter overflow in reports. Debian-specific changes include avoiding the use of /usr/local/, a man page in section 8, avoiding the use of printf when running in the background, successful building even if strtok_r is defined as a macro, and a change of the default MTA command string for mailing reports.
