Free p2p software for linux

YACY is a distributed Web crawler and also a caching HTTP/HTTPS proxy. Pages that pass through the proxy are indexed and can be searched using a built-in HTTP server.
YACY peers connect each other and form a P2P-based index exchange network based on distributed hash tables. Explicit web crawls can be done locally or collaboratively, forming a global search and distributed indexing engine for the Web.
YACY also provides URL filtering with blacklist sharing among other proxy peers, individual Web and servlet page hosting, a file sharing zone, and a database engine.
Main features:
- Search your own or the global index
- Crawl your own pages or start distributed crawling
- Run your peer to support other YaCy crawlers
- Provide Information on your peer using the built-in http-server, file-sharing zone and wiki
- Built-in caching http proxy
- Indexing benefits from the proxy cache; private information is not stored or indexed
- Usage of the proxy is not a requisite for web indexing, but it enables you to access the new top-level-domains .yacy
- Filter unwanted content like ad- or spyware; share your web-blacklist with other peers
- Easy installation! No additional database required!
- No central server!
- GPLed, freeware
Enhancements:
- An auto-updater and support for multiple search networks have been added, and the option to index intranet sites in separated networks has been enabled.
