Hi Folks

I'd like to introduce a YaCy System as a distributed search engine for the HAMNET

The important information on how to use it can be found here on our Webserver at DB0FHW: http://www.afu-ag.de/joomla/index.php?option=com_content&view=article&am...

If you let Google translate the page, unfortunatelly, you do not get a very good translation... http://translate.google.de/translate?sl=de&tl=en&js=n&prev=_t&am...

... So I'll explain it in a bit more detail.

YaCy is a free dezentralized search engine that anyone can use to build a search portal for their intranet General information can be found here: http://yacy.net/en/ ... So lets consider HAMNET as a kind of intranet.

We defined a root.unit for the system at DB0FHW, which has a quite good connection to the german HAMNET, an anybody can now connect a peer to this root.unit

This unit is shared to all peers, so the network will stay alive, even if DB0FHW goes down. Peers temporarely connect each other like a full mesh, so a peer only needs to know one other peer to find its way back into the network.

How do you connect peers now: 1. Download and install YaCy http://yacy.net/en/index.html 2. Do not start the YaCy Service, yet. 3. Edit the line "network.unit.definition" in your file "defaults/yacy.init". It should point to this URL now: http://yacy.db0fhw.ampr.org:8090/yacy.hamnet.unit 4. Start the YaCy Service

Philosophy: There sould be (minimum) one YaCy peer in each AS of the HAMNET, crawling the Servers INSIDE ist own AS! How often you want to crawl is your free choice. Just depending on the changes of the servers content. It it holds "hot news", you may host you yacy peer quite close to it an crawl every hour. If content changes weekly, crawl weekly... (if you have a huge AS, you may have more peers and define which of them is crawling which server)

So... Sounds not that hard at the end ;-) Give it a try
