I suggested several solutions to Gabriel Lopez. Let me list them, as

they may be of interest to other sites in the network:

 

1) If what he needs is a sample list of nodes, use the HOSTS.TXT file

   obtainable from the SRI NIC, nic.ddn.mil, found in the NETINFO:

   directory. Beware that this file is over 800kb in size.

 

2) If what he needs is a list of nodes from where to obtain information,

   software, etc., retrieve the ftp.list file, which lists most known

   nodes which allow anonymous FTP: it also contains a brief description

   of the information available at each node. This file is available from

   pilot.njin.net, and is found in the /pub/ftp-list directory; it is

   updated regularly.

 

3) If he needs to know what services are available on the Internet

   (something like the much missed BITNET SERVERS file), he should

   obtain the Internet Resources Guide, prepared by the NSF Network

   Services Center. This, together with option (2) is, by far, the most

   useful solution, as it gives you information you can really use.

   This is the descriptive blurb & copyright for the IRG:

 

*                         How to Use and Maintain This Guide

*

*            The Internet Resource Guide is intended to  inform  Internet

*            users about the services available to them on the network.

*

*            Similar Resources are grouped together  in  sections.   Each

*            resource  has  a separate entry that describes the resource,

*            identifies who can use the resource, explains how  to  reach

*            the  local  network via the Internet, and lists contacts for

*            more information.  For example, Section 1 lists special com-

*            puting  resources  on  the  Internet,  such as supercomputer

*            centers and centers for parallel computing.  Thus, research-

*            ers  interested  in using a supercomputer can browse through

*            the entries in Section 1 in search of a supercomputer center

*            that can accommodate their needs.

*

*            Users interested in locating a particular service can  check

*            the tables of contents at the start of each section.  In the

*            future, the NNSC expects to provide  an  index  that  allows

*            users to locate services based on keywords.

*

*                               Maintaining the Guide

*

*            The resource guide is designed to be kept  in  a  loose-leaf

*            notebook,  to  make  it  easy  to add or replace sections of

*            text.

*

*            The guide is distributed electronically by the NNSC.  If you

*            wish  to  receive the guide, send a note to <resource-guide-

*            request@nnsc.nsf.net>.  Each section  (new  or  updated)  is

*            sent  in an individual message, which contains both a plain-

*            text and a Postscript copy of a resource description.   (The

*            text in both versions is the same; the Postscript version is

*            generally easier to read).  Users can then add the new  sec-

*            tion, or replace the existing section, with the new copy.

*

*            If you prefer not to receive the guide via email, you may ftp

*            the  chapters that are currently available via anonymous ftp

*            from nnsc.nsf.net (in  directory  resource-guide).   We  are

*            maintaining  a  separate  mailing list of people who wish to

*            know only when a chapter becomes available for ftp.  If  you

*            wish   to  be  on  this  list,  please  send  a  message  to

*            <resource-guide-request@nnsc.nsf.net>.

*

*                                  Copyright Notice

I hope this information is useful to other network members.
