2176 IMPORTANT:
2177
2178 Please make sure NOW that you have created a user and group 'gnunet'
2179 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2180 type:
2181
2182   addgroup gnunetdns
2183   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2184
2185 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2186 'gnunet'.  Then, you can compile GNUnet with
2187
2188   make
2189
2190 After that, run (if necessary as 'root')
2191
2192   make install
2193
2194 to install everything.
2195
2196 Each GNUnet user should be added to the 'gnunet' group (may
2197 require fresh login to come into effect):
2198
2199   adduser USERNAME gnunet
2200
2201 (run the above command as root once for each of your users, replacing
2202 "USERNAME" with the respective login names).  If you have a global IP
2203 address, no further configuration is required.
2204
2205 For more detailed setup instructions, see https://docs.gnunet.org/
2206
2207 Optionally, download and compile gnunet-gtk to get a GUI for
2208 file-sharing and configuration.  This is particularly recommended
2209 if your network setup is non-trivial, as gnunet-setup can be
2210 used to test in the GUI if your network configuration is working.
2211 gnunet-setup should be run as the "gnunet" user under X.  As it
2212 does very little with the network, running it as "root" is likely
2213 also harmless.  You can also run it as a normal user, but then
2214 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2215 home directory in the end.
2216
2217 Once you have configured your peer, run (as the 'gnunet' user)
2218
2219   gnunet-arm -s
2220
2221 to start the peer.  You can then run the various GNUnet-tools as
2222 your "normal" user (who should only be in the group 'gnunet').
