name: who_sent_it.stp
keywords: network trace traffic simple
description: This script traces outgoing network packets using the netfilter probes (not requiring debuginfo), printing the source thread name/id and destination host:port. It may be filtered with the_dport and the_daddr globals, e.g., to watch only for DNS traffic (port 53), and/or only to the localhost (127.0.0.1).
