2168 IMPORTANT:
2169
2170 Please make sure NOW that you have created a user and group 'gnunet'
2171 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2172 type:
2173
2174   addgroup gnunetdns
2175   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2176
2177 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2178 'gnunet'.  Then, you can compile GNUnet with
2179
2180   make
2181
2182 After that, run (if necessary as 'root')
2183
2184   make install
2185
2186 to install everything.
2187
2188 Each GNUnet user should be added to the 'gnunet' group (may
2189 require fresh login to come into effect):
2190
2191   adduser USERNAME gnunet
2192
2193 (run the above command as root once for each of your users, replacing
2194 "USERNAME" with the respective login names).  If you have a global IP
2195 address, no further configuration is required.
2196
2197 For more detailed setup instructions, see https://docs.gnunet.org/
2198
2199 Optionally, download and compile gnunet-gtk to get a GUI for
2200 file-sharing and configuration.  This is particularly recommended
2201 if your network setup is non-trivial, as gnunet-setup can be
2202 used to test in the GUI if your network configuration is working.
2203 gnunet-setup should be run as the "gnunet" user under X.  As it
2204 does very little with the network, running it as "root" is likely
2205 also harmless.  You can also run it as a normal user, but then
2206 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2207 home directory in the end.
2208
2209 Once you have configured your peer, run (as the 'gnunet' user)
2210
2211   gnunet-arm -s
2212
2213 to start the peer.  You can then run the various GNUnet-tools as
2214 your "normal" user (who should only be in the group 'gnunet').
