1942 Please make sure NOW that you have created a user and group 'gnunet'
1943 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1945 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1947 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1948 'gnunet'. Then, you can compile GNUnet with
1951 After that, run (if necessary as 'root')
1953 to install everything.
1955 Each GNUnet user should be added to the 'gnunet' group (may
1956 require fresh login to come into effect):
1957 adduser USERNAME gnunet
1958 (run the above command as root once for each of your users, replacing
1959 "USERNAME" with the respective login names). If you have a global IP
1960 address, no further configuration is required.
1962 For more detailed setup instructions, see https://docs.gnunet.org/
1964 Optionally, download and compile gnunet-gtk to get a GUI for
1965 file-sharing and configuration. This is particularly recommended
1966 if your network setup is non-trivial, as gnunet-setup can be
1967 used to test in the GUI if your network configuration is working.
1968 gnunet-setup should be run as the "gnunet" user under X. As it
1969 does very little with the network, running it as "root" is likely
1970 also harmless. You can also run it as a normal user, but then
1971 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1972 home directory in the end.
1974 Once you have configured your peer, run (as the 'gnunet' user)
1976 to start the peer. You can then run the various GNUnet-tools as
1977 your "normal" user (who should only be in the group 'gnunet').
