2135 IMPORTANT:
2136
2137 Please make sure NOW that you have created a user and group 'gnunet'
2138 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2139 type:
2140
2141   addgroup gnunetdns
2142   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2143
2144 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2145 'gnunet'.  Then, you can compile GNUnet with
2146
2147   make
2148
2149 After that, run (if necessary as 'root')
2150
2151   make install
2152
2153 to install everything.
2154
2155 Each GNUnet user should be added to the 'gnunet' group (may
2156 require fresh login to come into effect):
2157
2158   adduser USERNAME gnunet
2159
2160 (run the above command as root once for each of your users, replacing
2161 "USERNAME" with the respective login names).  If you have a global IP
2162 address, no further configuration is required.
2163
2164 For more detailed setup instructions, see https://docs.gnunet.org/
2165
2166 Optionally, download and compile gnunet-gtk to get a GUI for
2167 file-sharing and configuration.  This is particularly recommended
2168 if your network setup is non-trivial, as gnunet-setup can be
2169 used to test in the GUI if your network configuration is working.
2170 gnunet-setup should be run as the "gnunet" user under X.  As it
2171 does very little with the network, running it as "root" is likely
2172 also harmless.  You can also run it as a normal user, but then
2173 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2174 home directory in the end.
2175
2176 Once you have configured your peer, run (as the 'gnunet' user)
2177
2178   gnunet-arm -s
2179
2180 to start the peer.  You can then run the various GNUnet-tools as
2181 your "normal" user (who should only be in the group 'gnunet').
