2150 IMPORTANT:
2151
2152 Please make sure NOW that you have created a user and group 'gnunet'
2153 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2154 type:
2155
2156   addgroup gnunetdns
2157   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2158
2159 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2160 'gnunet'.  Then, you can compile GNUnet with
2161
2162   make
2163
2164 After that, run (if necessary as 'root')
2165
2166   make install
2167
2168 to install everything.
2169
2170 Each GNUnet user should be added to the 'gnunet' group (may
2171 require fresh login to come into effect):
2172
2173   adduser USERNAME gnunet
2174
2175 (run the above command as root once for each of your users, replacing
2176 "USERNAME" with the respective login names).  If you have a global IP
2177 address, no further configuration is required.
2178
2179 For more detailed setup instructions, see https://docs.gnunet.org/
2180
2181 Optionally, download and compile gnunet-gtk to get a GUI for
2182 file-sharing and configuration.  This is particularly recommended
2183 if your network setup is non-trivial, as gnunet-setup can be
2184 used to test in the GUI if your network configuration is working.
2185 gnunet-setup should be run as the "gnunet" user under X.  As it
2186 does very little with the network, running it as "root" is likely
2187 also harmless.  You can also run it as a normal user, but then
2188 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2189 home directory in the end.
2190
2191 Once you have configured your peer, run (as the 'gnunet' user)
2192
2193   gnunet-arm -s
2194
2195 to start the peer.  You can then run the various GNUnet-tools as
2196 your "normal" user (who should only be in the group 'gnunet').
