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.
To configure the gnunet daemon edit
If you installed gnunet-gtk you can configure the client options with
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
# gnunet-arm -s # gnunet-fs-gtk
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, called gnunet-fuse, is being developed to make this process easier for a user. However, as of December 2008, there is little documentation for it and it is not even in AUR yet.
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. The '-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.
