2098 Please make sure NOW that you have created a user and group 'gnunet'
2099 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2103 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2105 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2106 'gnunet'. Then, you can compile GNUnet with
2110 After that, run (if necessary as 'root')
2114 to install everything.
2116 Each GNUnet user should be added to the 'gnunet' group (may
2117 require fresh login to come into effect):
2119 adduser USERNAME gnunet
2121 (run the above command as root once for each of your users, replacing
2122 "USERNAME" with the respective login names). If you have a global IP
2123 address, no further configuration is required.
2125 For more detailed setup instructions, see https://docs.gnunet.org/
2127 Optionally, download and compile gnunet-gtk to get a GUI for
2128 file-sharing and configuration. This is particularly recommended
2129 if your network setup is non-trivial, as gnunet-setup can be
2130 used to test in the GUI if your network configuration is working.
2131 gnunet-setup should be run as the "gnunet" user under X. As it
2132 does very little with the network, running it as "root" is likely
2133 also harmless. You can also run it as a normal user, but then
2134 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2135 home directory in the end.
2137 Once you have configured your peer, run (as the 'gnunet' user)
2141 to start the peer. You can then run the various GNUnet-tools as
2142 your "normal" user (who should only be in the group 'gnunet').
