2023 Please make sure NOW that you have created a user and group 'gnunet'
2024 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2028 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2030 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2031 'gnunet'. Then, you can compile GNUnet with
2035 After that, run (if necessary as 'root')
2039 to install everything.
2041 Each GNUnet user should be added to the 'gnunet' group (may
2042 require fresh login to come into effect):
2044 adduser USERNAME gnunet
2046 (run the above command as root once for each of your users, replacing
2047 "USERNAME" with the respective login names). If you have a global IP
2048 address, no further configuration is required.
2050 For more detailed setup instructions, see https://docs.gnunet.org/
2052 Optionally, download and compile gnunet-gtk to get a GUI for
2053 file-sharing and configuration. This is particularly recommended
2054 if your network setup is non-trivial, as gnunet-setup can be
2055 used to test in the GUI if your network configuration is working.
2056 gnunet-setup should be run as the "gnunet" user under X. As it
2057 does very little with the network, running it as "root" is likely
2058 also harmless. You can also run it as a normal user, but then
2059 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2060 home directory in the end.
2062 Once you have configured your peer, run (as the 'gnunet' user)
2066 to start the peer. You can then run the various GNUnet-tools as
2067 your "normal" user (who should only be in the group 'gnunet').
