2152 Please make sure NOW that you have created a user and group 'gnunet'
2153 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2157 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2159 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2160 'gnunet'. Then, you can compile GNUnet with
2164 After that, run (if necessary as 'root')
2168 to install everything.
2170 Each GNUnet user should be added to the 'gnunet' group (may
2171 require fresh login to come into effect):
2173 adduser USERNAME gnunet
2175 (run the above command as root once for each of your users, replacing
2176 "USERNAME" with the respective login names). If you have a global IP
2177 address, no further configuration is required.
2179 For more detailed setup instructions, see https://docs.gnunet.org/
2181 Optionally, download and compile gnunet-gtk to get a GUI for
2182 file-sharing and configuration. This is particularly recommended
2183 if your network setup is non-trivial, as gnunet-setup can be
2184 used to test in the GUI if your network configuration is working.
2185 gnunet-setup should be run as the "gnunet" user under X. As it
2186 does very little with the network, running it as "root" is likely
2187 also harmless. You can also run it as a normal user, but then
2188 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2189 home directory in the end.
2191 Once you have configured your peer, run (as the 'gnunet' user)
2195 to start the peer. You can then run the various GNUnet-tools as
2196 your "normal" user (who should only be in the group 'gnunet').
