2082 IMPORTANT:
2083
2084 Please make sure NOW that you have created a user and group 'gnunet'
2085 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2086 type:
2087
2088   addgroup gnunetdns
2089   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2090
2091 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2092 'gnunet'.  Then, you can compile GNUnet with
2093
2094   make
2095
2096 After that, run (if necessary as 'root')
2097
2098   make install
2099
2100 to install everything.
2101
2102 Each GNUnet user should be added to the 'gnunet' group (may
2103 require fresh login to come into effect):
2104
2105   adduser USERNAME gnunet
2106
2107 (run the above command as root once for each of your users, replacing
2108 "USERNAME" with the respective login names).  If you have a global IP
2109 address, no further configuration is required.
2110
2111 For more detailed setup instructions, see https://docs.gnunet.org/
2112
2113 Optionally, download and compile gnunet-gtk to get a GUI for
2114 file-sharing and configuration.  This is particularly recommended
2115 if your network setup is non-trivial, as gnunet-setup can be
2116 used to test in the GUI if your network configuration is working.
2117 gnunet-setup should be run as the "gnunet" user under X.  As it
2118 does very little with the network, running it as "root" is likely
2119 also harmless.  You can also run it as a normal user, but then
2120 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2121 home directory in the end.
2122
2123 Once you have configured your peer, run (as the 'gnunet' user)
2124
2125   gnunet-arm -s
2126
2127 to start the peer.  You can then run the various GNUnet-tools as
2128 your "normal" user (who should only be in the group 'gnunet').
