2138 Please make sure NOW that you have created a user and group 'gnunet'
2139 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2143 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2145 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2146 'gnunet'. Then, you can compile GNUnet with
2150 After that, run (if necessary as 'root')
2154 to install everything.
2156 Each GNUnet user should be added to the 'gnunet' group (may
2157 require fresh login to come into effect):
2159 adduser USERNAME gnunet
2161 (run the above command as root once for each of your users, replacing
2162 "USERNAME" with the respective login names). If you have a global IP
2163 address, no further configuration is required.
2165 For more detailed setup instructions, see https://docs.gnunet.org/
2167 Optionally, download and compile gnunet-gtk to get a GUI for
2168 file-sharing and configuration. This is particularly recommended
2169 if your network setup is non-trivial, as gnunet-setup can be
2170 used to test in the GUI if your network configuration is working.
2171 gnunet-setup should be run as the "gnunet" user under X. As it
2172 does very little with the network, running it as "root" is likely
2173 also harmless. You can also run it as a normal user, but then
2174 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2175 home directory in the end.
2177 Once you have configured your peer, run (as the 'gnunet' user)
2181 to start the peer. You can then run the various GNUnet-tools as
2182 your "normal" user (who should only be in the group 'gnunet').
