2123 IMPORTANT:
2124
2125 Please make sure NOW that you have created a user and group 'gnunet'
2126 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2127 type:
2128
2129   addgroup gnunetdns
2130   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2131
2132 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2133 'gnunet'.  Then, you can compile GNUnet with
2134
2135   make
2136
2137 After that, run (if necessary as 'root')
2138
2139   make install
2140
2141 to install everything.
2142
2143 Each GNUnet user should be added to the 'gnunet' group (may
2144 require fresh login to come into effect):
2145
2146   adduser USERNAME gnunet
2147
2148 (run the above command as root once for each of your users, replacing
2149 "USERNAME" with the respective login names).  If you have a global IP
2150 address, no further configuration is required.
2151
2152 For more detailed setup instructions, see https://docs.gnunet.org/
2153
2154 Optionally, download and compile gnunet-gtk to get a GUI for
2155 file-sharing and configuration.  This is particularly recommended
2156 if your network setup is non-trivial, as gnunet-setup can be
2157 used to test in the GUI if your network configuration is working.
2158 gnunet-setup should be run as the "gnunet" user under X.  As it
2159 does very little with the network, running it as "root" is likely
2160 also harmless.  You can also run it as a normal user, but then
2161 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2162 home directory in the end.
2163
2164 Once you have configured your peer, run (as the 'gnunet' user)
2165
2166   gnunet-arm -s
2167
2168 to start the peer.  You can then run the various GNUnet-tools as
2169 your "normal" user (who should only be in the group 'gnunet').
