Mirroring Kidlink Material to Local Web (LWeb) Servers

Kidlink encourages a full mirror of KWeb (excluding the pages developed locally, and already existing on the server). The current size of KWeb is 225MB and is estimated to rise to 300+MB over the next 12 months.

Authorization

Authorization to carry a local mirror of KWeb is given by KWebmaster based on a written description of the development plan. This description must contain:

• A description of the directories that LWebmaster plans to mirror. As a minimum, LWebmaster agrees to mirror the following directories: (Refer to KWebmaster for current list.)
• Planned mirroring frequency (at least once per week)
• The name and email address of the individual in LWebmaster's organization who will be in charge of mirroring.

Assumptions

• LWebmaster agrees not to change the mirrored pages in any way.
• LWebmaster agrees to mirror at least once a week. Ideally on a daily basis.
• LWebmaster will mirror the pages to a /kidlink/ subdirectory on his web server. This subdirectory will contain only Kidlink material.
• Special authorization is required by Kidlink's project director if it is desired to use the term "kidlink" in the domain name of this server.

Authorised Kidlink Mirrors

Listed below are authorized Kidlink mirror sites divided into two groups:

1. Sites containing a complete and up-to-date mirror of KWeb
2. Sites which are mirrored to KWeb but which do not carry a local mirror of KWeb

Universe ( KWeb )	Mirrored to:	Local Server ( LWeb )	Frequency	Contact

Method of Mirroring

In this example, KWeb is mirrored to the local machine so all relative addresses will work.
Create at least three directories on your local server using this simplified example of kidlink.dk:

Remember: KWeb means Kidlink Web and LWeb means local Web.

Mirror Packages

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 timestamps 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/
or
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@icparc.ic.ac.uk.

But please do NOT do this unless you have the time to work on mirror.

Sample .ini file to get mirroring started:
