2109 IMPORTANT:
2110
2111 Please make sure NOW that you have created a user and group 'gnunet'
2112 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2113 type:
2114
2115   addgroup gnunetdns
2116   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2117
2118 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2119 'gnunet'.  Then, you can compile GNUnet with
2120
2121   make
2122
2123 After that, run (if necessary as 'root')
2124
2125   make install
2126
2127 to install everything.
2128
2129 Each GNUnet user should be added to the 'gnunet' group (may
2130 require fresh login to come into effect):
2131
2132   adduser USERNAME gnunet
2133
2134 (run the above command as root once for each of your users, replacing
2135 "USERNAME" with the respective login names).  If you have a global IP
2136 address, no further configuration is required.
2137
2138 For more detailed setup instructions, see https://docs.gnunet.org/
2139
2140 Optionally, download and compile gnunet-gtk to get a GUI for
2141 file-sharing and configuration.  This is particularly recommended
2142 if your network setup is non-trivial, as gnunet-setup can be
2143 used to test in the GUI if your network configuration is working.
2144 gnunet-setup should be run as the "gnunet" user under X.  As it
2145 does very little with the network, running it as "root" is likely
2146 also harmless.  You can also run it as a normal user, but then
2147 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2148 home directory in the end.
2149
2150 Once you have configured your peer, run (as the 'gnunet' user)
2151
2152   gnunet-arm -s
2153
2154 to start the peer.  You can then run the various GNUnet-tools as
2155 your "normal" user (who should only be in the group 'gnunet').
