2134 Please make sure NOW that you have created a user and group 'gnunet'
2135 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2139 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2141 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2142 'gnunet'. Then, you can compile GNUnet with
2146 After that, run (if necessary as 'root')
2150 to install everything.
2152 Each GNUnet user should be added to the 'gnunet' group (may
2153 require fresh login to come into effect):
2155 adduser USERNAME gnunet
2157 (run the above command as root once for each of your users, replacing
2158 "USERNAME" with the respective login names). If you have a global IP
2159 address, no further configuration is required.
2161 For more detailed setup instructions, see https://docs.gnunet.org/
2163 Optionally, download and compile gnunet-gtk to get a GUI for
2164 file-sharing and configuration. This is particularly recommended
2165 if your network setup is non-trivial, as gnunet-setup can be
2166 used to test in the GUI if your network configuration is working.
2167 gnunet-setup should be run as the "gnunet" user under X. As it
2168 does very little with the network, running it as "root" is likely
2169 also harmless. You can also run it as a normal user, but then
2170 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2171 home directory in the end.
2173 Once you have configured your peer, run (as the 'gnunet' user)
2177 to start the peer. You can then run the various GNUnet-tools as
2178 your "normal" user (who should only be in the group 'gnunet').
