2092 IMPORTANT:
2093
2094 Please make sure NOW that you have created a user and group 'gnunet'
2095 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2096 type:
2097
2098   addgroup gnunetdns
2099   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2100
2101 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2102 'gnunet'.  Then, you can compile GNUnet with
2103
2104   make
2105
2106 After that, run (if necessary as 'root')
2107
2108   make install
2109
2110 to install everything.
2111
2112 Each GNUnet user should be added to the 'gnunet' group (may
2113 require fresh login to come into effect):
2114
2115   adduser USERNAME gnunet
2116
2117 (run the above command as root once for each of your users, replacing
2118 "USERNAME" with the respective login names).  If you have a global IP
2119 address, no further configuration is required.
2120
2121 For more detailed setup instructions, see https://docs.gnunet.org/
2122
2123 Optionally, download and compile gnunet-gtk to get a GUI for
2124 file-sharing and configuration.  This is particularly recommended
2125 if your network setup is non-trivial, as gnunet-setup can be
2126 used to test in the GUI if your network configuration is working.
2127 gnunet-setup should be run as the "gnunet" user under X.  As it
2128 does very little with the network, running it as "root" is likely
2129 also harmless.  You can also run it as a normal user, but then
2130 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2131 home directory in the end.
2132
2133 Once you have configured your peer, run (as the 'gnunet' user)
2134
2135   gnunet-arm -s
2136
2137 to start the peer.  You can then run the various GNUnet-tools as
2138 your "normal" user (who should only be in the group 'gnunet').
