2143 IMPORTANT:
2144
2145 Please make sure NOW that you have created a user and group 'gnunet'
2146 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2147 type:
2148
2149   addgroup gnunetdns
2150   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2151
2152 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2153 'gnunet'.  Then, you can compile GNUnet with
2154
2155   make
2156
2157 After that, run (if necessary as 'root')
2158
2159   make install
2160
2161 to install everything.
2162
2163 Each GNUnet user should be added to the 'gnunet' group (may
2164 require fresh login to come into effect):
2165
2166   adduser USERNAME gnunet
2167
2168 (run the above command as root once for each of your users, replacing
2169 "USERNAME" with the respective login names).  If you have a global IP
2170 address, no further configuration is required.
2171
2172 For more detailed setup instructions, see https://docs.gnunet.org/
2173
2174 Optionally, download and compile gnunet-gtk to get a GUI for
2175 file-sharing and configuration.  This is particularly recommended
2176 if your network setup is non-trivial, as gnunet-setup can be
2177 used to test in the GUI if your network configuration is working.
2178 gnunet-setup should be run as the "gnunet" user under X.  As it
2179 does very little with the network, running it as "root" is likely
2180 also harmless.  You can also run it as a normal user, but then
2181 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2182 home directory in the end.
2183
2184 Once you have configured your peer, run (as the 'gnunet' user)
2185
2186   gnunet-arm -s
2187
2188 to start the peer.  You can then run the various GNUnet-tools as
2189 your "normal" user (who should only be in the group 'gnunet').
