What is it ?
s6-networking is a suite of small networking utilities for Unix systems.
It includes command-line client and server management, TCP access
control, privilege escalation across UNIX domain sockets, IDENT
protocol management and clock synchronization.
If the underlying
skalibs has been
compiled with IPv6 support, s6-networking is IPv6-ready.
