The GateD documentation is now all written in
HyperText Markup Language. It has been
developed primarily with the NCSA Mosaic for the X Window System
WWW/HTML viewer, but should work with any
viewer. Mosaic viewers for the X Window System, the Apple Macintosh and for
Microsoft Windows are available from
ftp.ncsa.uiuc.edu in the Mosaic

The GateD web pages at www.gated.org has the latest on-line documentation for the following versions of GateD:
The document consists of the following sections:
GateD is a modular software program consisting of core services, a routing database, and protocol modules supporting multiple routing protocols (RIP versions 1 and 2, DCN HELLO, OSPF version 2, EGP version 2 and BGP version 2 through 4.) GateD was first used to interconnect the NSFNET and the emerging regional networks, and to implement filtered routing based on policy. GateD allows the network administrator to control import and export of routing information by individual protocol, by source and destination autonomous system, source and destination interface, previous hop router, and specific destination address. The network administrator can specify a preference level for each combination of routing information being imported by using a flexible masking capability. Once the preference levels are assigned, GateD makes a decision on which route to use independent of the protocols involved.
GateD is designed to handle dynamic routing with a routing database built from information exchanged by routing protocols.
If you need assistance or have any questions, don't bang your head against the wall. Post to the mailing list. There are many people with GateD experience who may be able to take a moment to help.
When reporting a problem with GateD, several pieces of information will greatly assist in debugging:
It helps to provide this as both the output
netstat -in (
netstat -i -n on BSD 4.2
based systems) and an
ifconfig for each interface (
-a will work for some versions of SunOS 4 and later.
The Routing table may be listed by using i.e.
netstat -rn (
netstat -r -n
on BSD 4.2 based systems)
To get this start GateD with
is short for

file will not get all this information because GateD scans the interfaces
before parsing the config file. So you must specify tracing on the command
To get this start GateD and do a "gdc dump" using the gdc utility gated provides.
If it is a RIP problem, turn on RIP tracing, an EGP problem, turn on EGP tracing.

GateD has code in two source trees:
The Consortium code is released in 3 separate versions:
The Consortium code is developed out of a single library for releases 4, 5, and 6. These releases have the nice features of being "autoconfed" and will adapt more easily to your environment that the public GateD code. You can probably obtain a "no-cost" license to use this code. Please see the next section for details.
The Public GateD code is available for anonymous ftp to all people in the Internet. GateD Public code cannot be redistributed without obtaining a redistribution license for GateD Version 3.
You do not need to be a member to obtain the Public GateD code or to apply for a redistribution license.
anonymous FTP from:
The GateD Public code has been supported by Merit, the GateD Consortium members, grants, and research institutions. This varied group of people have supported making high quality software available to the Internet at no cost for academic and research applications.
Support for GateD Public code has come from:
Merit supports the public domain software development with people and equipment resources.
An example of such generous members are: Hitachi and Digital. Hitachi has created test tools and asked that much of it's code be donated back to the public arena. Digital asked that IPv6 code be available in the public domain.
NSF support a great deal of GateD's early development via the NSFNET projects. In addition, some of the early code was also developed by IBM as part of their contribution to the NSFNET.
The FAA supported the development of the IDRP code for the FAA project. DARPA funded some of the work for the base GateD code.
The CAIRN project has helped develop the BGP-4++ code.
Various Research Institutions are supporting the GateD Consortium development of the public code as Academic Supporting members:
INRIA is specifically supporting the IPv6 operations.
The GateD Consortium code is developed via Commercial companies adding their resources to the Internet. This code is available to the Internet for "Academic and Research" use. Our definition of Academic and Research use includes anyone who wants to use or examine the code, but not use it in a commercial product or commercial service.
You can probably obtain a "no-cost" license to use this code even if you are at a commercial companyif you are:
The Consortium code is released in 3 separate versions:
The Consortium code is developed out of a single library for releases 4 (4.2 and above), 5 and 6. These releases have the nice features of being "autoconfed" and will adapt more easily to your environment that the public GateD code.
Release 4.0 and 4.1 are not "autoconf", but contain additional features for protocols. Please click here for a description of the code additions to GateD-Unicast.
The Consortium GateD code is available for ftp via a web interface at www.gated.org
which is the Code, Tools and Documents section.
Several versions of GateD are available for ftp. Any source code for versions of Consortium GateD versions of code (versions 4, 5, and 6) require a membership id and password. You can obtain these at "no-cost" by becoming a member of GateD for any particular version.
We urge you to make sure you are using the latest copy of GateD. GateD Consortium is easy to obtain over the network if you are a GateD member. If you are not a member, it is easy to become a member. Please see the section below.
GateD members can obtain the latest GateD source, tools and documentation from www.gated.merit.edu
If you are planning, to use Gated in a Commercial product or a Internet Service product you should apply one of the following membership categories:

If you are planning to use GateD for Academic and Research purposes, you may apply for Academic and Research Membership. This membership is available to those using GateD for research and academic purposes only. Commercial uses include using GateD in a product that is sold as a commercial product or used to provide a commerical service.
Our definition of what constitutes "Academic and Research" purposes is very "broad". Our business is to build and transfer technology. Merit, Inc. is a research institution which transfers technology from Academic and Research to the Internet. The GateD Consortium to support the routing technology in the Internet. Please apply if you think you investigating GateD for:
Please use the Academic and Research license to look at the code prior to becoming a Commercial member. GateD internal's documentation is available for members.
We are trying to add additional tools and monitoring features to GateD.
You can become a

The GateDaemon Consortium presents a formal structure to support and expand the current successful collaborations already in place to develop GateD functionality.
Membership is open to all organizations interested in supporting and participating in development of internetwork routing protocols. Membership is not a prerequisite for licensing of GateD source code. More information about the GateD Consortium may be obtained from the GateD Consortium Web Page or my e-mail to firstname.lastname@example.org.
The GateD source code, tools and documentation is based on three different product lines: GateD Unicast, GateD Multicast, GateD IPv6. In each of the products, has it's own software base, release dates, and product desciptions.
New GateD Source code, tools and internal documentation is available to GateD members only . Binaries for utilities or on-line documentation is available for anonymous ftp or via the web.
Members of the Academic and Research community can join the the Merit GateD Consortium at no cost by simply filling out a GateD Academic and Research membership.
