s6-networking
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.
Optionally, it also includes command-line TLS/SSL tools for
secure communications.
If the underlying
skalibs has been
compiled with IPv6 support, s6-networking is IPv6-ready.
The s6- prefix is slightly misleading, and probably a naming
mistake. This package is not, stricto sensu, a part of the
s6 ecosystem, and it is nowhere near a requirement for a
s6-based installation.
However, it provides useful networking utilities often used with s6,
so keeping the prefix makes some kind of sense; you can see s6-networking,
as well as its dependency s6-dns,
as extensions to the s6 ecosystem.
Installation
Requirements
- A POSIX-compliant system with a standard C development environment
- GNU make, version 3.81 or later
- skalibs version
2.14.2.0 or later. It's a build-time requirement. It's also a run-time
requirement if you link against the shared version of the skalibs
library.
- (Optional, but recommended) execline version
2.9.6.0 or later. It's a build-time and run-time requirement.
- s6 version
2.13.0.0 or later. It's a build-time and run-time requirement.
- s6-dns version
2.3.7.2 or later. It's a build-time requirement. It's also a run-time
requirement if you link against the shared version of the s6-dns
libraries.
- If you want to build the secure communication tools:
The chosen library is a build-time requirement, and also a
run-time requirement if you link against its shared version.
Licensing
s6-networking is free software. It is available under the
ISC license.
