2142 Please make sure NOW that you have created a user and group 'gnunet'
2143 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2147 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2149 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2150 'gnunet'. Then, you can compile GNUnet with
2154 After that, run (if necessary as 'root')
2158 to install everything.
2160 Each GNUnet user should be added to the 'gnunet' group (may
2161 require fresh login to come into effect):
2163 adduser USERNAME gnunet
2165 (run the above command as root once for each of your users, replacing
2166 "USERNAME" with the respective login names). If you have a global IP
2167 address, no further configuration is required.
2169 For more detailed setup instructions, see https://docs.gnunet.org/
2171 Optionally, download and compile gnunet-gtk to get a GUI for
2172 file-sharing and configuration. This is particularly recommended
2173 if your network setup is non-trivial, as gnunet-setup can be
2174 used to test in the GUI if your network configuration is working.
2175 gnunet-setup should be run as the "gnunet" user under X. As it
2176 does very little with the network, running it as "root" is likely
2177 also harmless. You can also run it as a normal user, but then
2178 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2179 home directory in the end.
2181 Once you have configured your peer, run (as the 'gnunet' user)
2185 to start the peer. You can then run the various GNUnet-tools as
2186 your "normal" user (who should only be in the group 'gnunet').
