“Today I’ll show you two tools to be used int the
terminal to monitor your network and the active connections:
iptstate and pkstat IPTState“IPTState is a top-like interface to your netfilter
connection-tracking table.“Using iptstate you interactively watch where traffic crossing
your netfilter/iptables firewall is going, sort by various
criteria, limit the view by various criteria. But it doesn’t stop
there: as of version 2.2.0 you can even delete states from the
table!”
