The YaCy documentation says:
A Principal is a Senior peer that uploaded an additional peer-list to a server. This list supports other peers to get in contact with the existing Yacy network to perform a global search. If you have the possibility to upload a file to an FTP server, you can become a Principal by uploading your peer-list.
Question: where can I get this peer-list or how to create it and how to connect it correctly so that the peer becomes the Principal one?
Don’t worry about the peer-list, your YaCy peer maintains it. What you want to do is the configuration of a upload location of the list and that is in this path of your interface: /Settings_p.html?page=seed
Once you configured a method to upload the list and an url where everyone can download the list, and also if your peer is already a senior peer, your peer becomes a principal peer.
Thank you very much for your response!
Without it, it was not obvious from the YaCy interface, that my peer would create the list on its own.
I did the following.
Submit the path in the local file system in File Location field:
<...>YaCy\htroot\yacy\seed.txt
Select Upload Method: File
URL: http://<myhostname:port>/yacy/seed.txt
after that: Submit in the Upload Method field.
Everything turned out right. The file <…>\htroot\yacy\seed.txt was created and the peer became the Principal one.
Currently the size of the seed.txt file is about 55 kb.
Now I discovered that the link http://<myhostname:port>/yacy/seed.txt has disappeared and the peer has switched to “senior” status.
I restored the link manually, but is it really supposed to be so that it will spontaneously clears every 5 days?
