Network Time Protocol (NTP) managed by Network Time Foundation

NTP

NTP (Network Time Protocol) is an implementation of the NTP-related RFCs (and proposed RFCs) and provides an openly redistributable reference implementation of the software, including:

  • An NTP server (ntpd, and the proposed NTP4 RFC)
  • An SNTP client (sntpd, and RFC 2030, and the proposed SNTPv4 Draft RFC)
  • Tools for verifying, monitoring and configuring the proper operation of the NTP server

The ntpd Server is used on a significant number of computers and routers on the Internet, in orbit around the planet, and even in outer space, providing a robust and stable platform on top of which an organization’s timing architecture can be built.

More information on the software, legal issues, security advisories, etc. can be found on the NTP project web site.

The official reference implementation of NTP and its documentation are produced by the Network Time Protocol Project, while the NTP Public Services Project, hosted at ISC, provides distribution, support, and additional development resources. Read about the latest Security information related to NTP.

InterNetNews Package (INN)

INN

The InterNetNews package (INN) is a complete Usenet system. It includes innd, an NNTP server, and nnrpd, a newsreading server. INN separates hosts that feed you news from those that have users reading news. INN was originally written by Rich Salz (grab the USENIX paper Rich wrote about it here). ISC took over development of INN in 1996 after Rich was unable to continue supporting it and many variants of the software were forming.

If you are interested in receiving notice of future releases of INN, you can subscribe to the inn-announce mailing list.

At this time, ISC regrets that we do not have the resources to offer support or training on the INN software. As partnerships in this area develop, we will post updated information here.

Internet Routing Registry Toolset (IRRToolSet)

IRRToolSet

The “Internet Routing Registry Toolset” (IRRToolSet) project at ISC is an activity proposed by the RIPE NCC. This project has been migrated from the USC Information Sciences Institute, where it was developed in 1997-2001 as the “Routing Arbiter ToolSet” (RAToolSet) project. As the RAToolSet is no longer developed by ISI but is used worldwide, the RIPE NCC proposed to migrate this project to the RIPE NCC in order to continue its development and support. The original name of the project was preserved during the transition process, but has been finally changed to IRRToolSet. Currently, the RIPE NCC has transfered maintainance of this toolset to ISC, who will be accepting code from the community and providing code maintainance.

Goals

IRRToolSet is a suite of policy analysis tools to operate with routing policies in RPSL [RFC 2622] format, registered in Internet Routing Registry(IRR). The main goal of the project is to make routing information more convenient and useful for network engineers, by providing tools for automated router configuration, routing policies analysis, and maintenance.

Functionality

The project consists of the following tools:

  • RtConfig: analyzes the routing policies registered in the Internet Routing Registry (IRR) and produces router configuration files;
  • CIDRAdvisor: suggests safe cidr aggregates (i.e. those that do not violate any policy constraints) that an Autonomous System (AS) can advertise to each of its neighbour ASes;
  • peval: low level policy evaluation tool that can be used to write router configuration generators;
  • prtraceroute: prints the route and policy information packets take to a network host;
  • prpath: enumerates a list of paths between Autonomous System and specified destination;
  • aoe: C++/Tcl/Tk program that displays the aut-num object for the specified Autonomous System;
  • roe: C++/Tcl/Tk program that lists the routes registered by the specified autonomous system;
  • rpslcheck(prcheck): syntax-checks the aut-num object for Autonomous System registered in the Internet Routing Registry (IRR).

Current Status

IRRToolset version 5.0.0 was released by ISC on 16 Jul 2010.

The project is implemented in C++ on a UNIX platform. It has been ported successfully to many platforms including: Sun Sparc stations running SunOS 4.1.3 or Solaris, FreeBSD, DEC Alphas running OSF/1, BSDI, Linux and NetBSD.

Versions starting from 4.7.2 contain aoe as well as a number of bug fixes.

Progress has been made with RPSLng (RPSL with IPv6 and multicast extentions) implementation in IRRToolSet. The prototype release contains peval, rpslcheck and RtConfig tools which already work with the new dictionary. Check the ftp site for the release. Any comments and suggestions about the prototype are appreciated.

Re-implemented peval and RtConfig are also available as a CGI script.

OpenReg

OpenReg

OpenReg is an implementation of a domain registry, such as might be used by top-level domain operators to manage the delegation of domains in a “shared registry” environment.
