2148 Please make sure NOW that you have created a user and group 'gnunet'
2149 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2153 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2155 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2156 'gnunet'. Then, you can compile GNUnet with
2160 After that, run (if necessary as 'root')
2164 to install everything.
2166 Each GNUnet user should be added to the 'gnunet' group (may
2167 require fresh login to come into effect):
2169 adduser USERNAME gnunet
2171 (run the above command as root once for each of your users, replacing
2172 "USERNAME" with the respective login names). If you have a global IP
2173 address, no further configuration is required.
2175 For more detailed setup instructions, see https://docs.gnunet.org/
2177 Optionally, download and compile gnunet-gtk to get a GUI for
2178 file-sharing and configuration. This is particularly recommended
2179 if your network setup is non-trivial, as gnunet-setup can be
2180 used to test in the GUI if your network configuration is working.
2181 gnunet-setup should be run as the "gnunet" user under X. As it
2182 does very little with the network, running it as "root" is likely
2183 also harmless. You can also run it as a normal user, but then
2184 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2185 home directory in the end.
2187 Once you have configured your peer, run (as the 'gnunet' user)
2191 to start the peer. You can then run the various GNUnet-tools as
2192 your "normal" user (who should only be in the group 'gnunet').
