Guidelines for redistribution of
the Online World resources handbook

You are encouraged to redistribute The Online World handbook's web pages through your free information systems. Permission to do so is hereby granted.
If you do, please tell Odd de Presno after the fact, or write to ask for help.

Note: If your offering is a for-pay service, you must have written permission. We must also agree on the financial side of such an action.

Mirroring the handbook's web pages

There is no charge for this service. The terms of the agreement are very liberal, however a mirror agreement is required. Sites already on our list of authorized mirror sites do not need to re-apply.
To become an authorized mirror site, you must agree to these simple requirements:

  • Mirror sites must carry whatever appears under the top-level http://home.eunet.no/~presno/ directory, except the contents of the http://home.eunet.no/~presno/datatid/ directory. These pages use relative URLs to make them portable.
    All information files must be included, and files must not be compressed unless they already exist in compressed form. No additional files or directories may be added without the express permission of Odd de Presno.
  • Access must be free except for normal connect charges, if any. The mirror site shall be accessible by all Internet users, although limits on the number of simultaneous connections may be imposed to control network bandwidth usage.
  • You must affirm that you have read and understand the copyright notice found in the file http://home.eunet.no/~presno/bok/f.html.
  • Republication of the material in any form is not permitted without the express permission of Odd de Presno.

Authorized mirror sites are also permitted to mirror the files in the http://home.eunet.no/~presno/datatid/ directory.
Mirroring can start upon completion of a mirror site agreement.

Mirroring details

The Online World resources handbook's World Wide Web site consists of the following directories:

http://home.eunet.no/~presno/   around 1,6 MB (1999)

http://home.eunet.no/~presno/datatid/ around 2.9 MB

All hyperlinks use relative paths.

Method of mirroring

The preferred method of mirroring is as follows:

 
Date: 17 Apr 2000
From: w8sdz@Simtel.Net (Keith Petersen)
Subject: Mirror software

Mirror is a package written in Perl that uses the ftp protocol to
duplicate a directory hierarchy between the machine it is run on and a
remote host.  It avoids copying files unnecessarily by comparing the
file time stamps and sizes before transferring.  Amongst other things
can optionally compress, gzip, and split files.

It was written for use by archive maintainers but can be used by
anyone wanting to transfer a lot of files over ftp.

The latest version of mirror is available from:

http://sunsite.org.uk/packages/mirror/
ftp://sunsite.org.uk/packages/mirror/


Mirror is part of a family of related programs.  The others are ftpmail
and ftpcat.  Ftpmail is a mail responder and ftpcat cats a remote file.
These are to be found in 

ftp://sunsite.org.uk/packages/ftpmail/ , and
ftp://sunsite.org.uk/packages/ftpcat/.

 
If you are interested in developing mirror (not just getting the
latest releases but actually doing work) there is a mailing list
mirror-people@doc.ic.ac.uk.  Subscribe by emailing to
mirror-people-request@doc.ic.ac.uk.   But please do NOT do this unless
you have the time to work on mirror.

Comment:
Most mirror hosts world wide have been able to make the mirror copies using the default settings given above. In just case (Brazil), they had to increase the timeout setting in the last line above.

To use this package for mirroring, ftp to ftphome.eunet.no. Login: tow The password will be given you upon request.

Good luck!
