# getipacctg uses clogin to login to a cisco router, collect the o/p of
# show ip accounting, and sort by the greatest number of bytes. If a
# second argument is supplied, it is a number indicating the top N producers.
# a third (3 to N) argument(s) specify a prefix(es) to match/select src/dst
# IPs, while others will be filtered.
#
# usage: getipacctg <router name> [<number of lines off the top>] \
# [<src/dest prefix filter> [...]]
# example:
# getipacctg router 25 192.168.0.0/24
# will display the top 25 for src or dst ip's within prefix
# 192.168.0.0/24
