conns provides a tcpdump like utility to capture unique IP hits based on an active pcap filter. Currently only TCP & UDP protocols are potentially counted.
Essentially a less awkward tcpdump | awk | sort | uniq.
Usage:
conns [-r] [filter command]
-r enables name resolution of IPs on collection
filter command is currently required to be a single string
to-do:
- move to new dns resolution funcs
- concat all unparsed args into the pcap filter string
