2131 IMPORTANT:
2132
2133 Please make sure NOW that you have created a user and group 'gnunet'
2134 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2135 type:
2136
2137   addgroup gnunetdns
2138   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2139
2140 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2141 'gnunet'.  Then, you can compile GNUnet with
2142
2143   make
2144
2145 After that, run (if necessary as 'root')
2146
2147   make install
2148
2149 to install everything.
2150
2151 Each GNUnet user should be added to the 'gnunet' group (may
2152 require fresh login to come into effect):
2153
2154   adduser USERNAME gnunet
2155
2156 (run the above command as root once for each of your users, replacing
2157 "USERNAME" with the respective login names).  If you have a global IP
2158 address, no further configuration is required.
2159
2160 For more detailed setup instructions, see https://docs.gnunet.org/
2161
2162 Optionally, download and compile gnunet-gtk to get a GUI for
2163 file-sharing and configuration.  This is particularly recommended
2164 if your network setup is non-trivial, as gnunet-setup can be
2165 used to test in the GUI if your network configuration is working.
2166 gnunet-setup should be run as the "gnunet" user under X.  As it
2167 does very little with the network, running it as "root" is likely
2168 also harmless.  You can also run it as a normal user, but then
2169 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2170 home directory in the end.
2171
2172 Once you have configured your peer, run (as the 'gnunet' user)
2173
2174   gnunet-arm -s
2175
2176 to start the peer.  You can then run the various GNUnet-tools as
2177 your "normal" user (who should only be in the group 'gnunet').
