On Debian and Ubuntu GNU/Linux, type: addgroup gnunetdns adduser --system --group --disabled-login --home /var/lib/gnunet gnunet Make sure that '/var/lib/gnunet' is owned (and writable) by user 'gnunet'. Then, you can compile GNUnet with make After that, run (if necessary as 'root') make install to install everything. Each GNUnet user should be added to the 'gnunet' group (may require fresh login to come into effect): adduser USERNAME gnunet (run the above command as root once for each of your users, replacing "USERNAME" with the respective login names). If you have a global IP address, no further configuration is required. For more detailed setup instructions, see https://docs.gnunet.org/ Optionally, download and compile gnunet-gtk to get a GUI for file-sharing and configuration. This is particularly recommended if your network setup is non-trivial, as gnunet-setup can be used to test in the GUI if your network configuration is working. gnunet-setup should be run as the "gnunet" user under X. As it does very little with the network, running it as "root" is likely also harmless. You can also run it as a normal user, but then you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's home directory in the end. Once you have configured your peer, run (as the 'gnunet' user) gnunet-arm -s to start the peer. You can then run the various GNUnet-tools as your "normal" user (who should only be in the group 'gnunet'). ])
