GNUnet is a framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. Currently, the service implemented on the framework serves to perform censorship-resistant file-sharing.
See also Wikipedia:GNUnet.
GNUnet can be installed with the package. If you also want to use the graphical interface, install . Alternatively, for the most recent experimental version, the git versions are available on AUR as well, under AUR and AUR respectively.
Alternatively, to start the peer immediately in a terminal:
# gnunet-arm -s

To use gnunet-gtk to download a file, just search for the file in the Filesystem tab. When you see the file you want, just download it as you would with any other P2P file-sharing program. Start it with:
Uploading files to the gnunet network is more complicated. GNUnet differentiates between indexing a file and inserting a file. The details can be read at the framework's website. The following steps explain how to share data with the network, and are a shortened form of the instructions found on this page.
The following steps may have to be done manually. A module, calledAUR, has been developed to make this process easier for a user.
To index a file/directory
gnunet-insert [-n] [-k keword1] [-k keyword 2] [-m TYPE:VALUE] filename
It is not required to add keywords, but it is recommended. This is because GNUnet does not allow searching by filename, but by keywords. Libextractor, which is a dependency of gnunet, will extract keywords from the file, but you may wish to enter keywords of your own.
-m option is for meta-data. This is data (about the file) that other users of gnunet will see when your files show up during their searches. For further details, see the gnunet.org online documentation. The
-n option is used to insert a file/directory into the gnunet MySQL/sqlite database, instead of just indexing it.
To unindex a file/directory
Suppose you have forgotten which files you indexed, you can look up the pointers in the directory
GNUNET_HOME=/var/lib/gnunet (set by
Modifying and removing indexed files
- When you modify a file, the URI of the file changes. Therefore, GNUnet considers this to be a completely different file. Therefore, make sure that the original file is unindexed (using the gnunet-unindex command), modify the file, and then index the new file to make it accessible through the network.
- If you want to move/remove a file from your system, then you should unindex it first.
Web User Interface
A Web interface for GNUnet exists and is available on AUR asAUR.
