1934 Please make sure NOW that you have created a user and group 'gnunet'
1935 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1936         addgroup gnunetdns
1937         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1938
1939 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1940 'gnunet'.  Then, you can compile GNUnet with
1941         make
1942
1943 After that, run (if necessary as 'root')
1944         make install
1945 to install everything.
1946
1947 Each GNUnet user should be added to the 'gnunet' group (may
1948 require fresh login to come into effect):
1949         adduser USERNAME gnunet
1950 (run the above command as root once for each of your users, replacing
1951 "USERNAME" with the respective login names).  If you have a global IP
1952 address, no further configuration is required.
1953
1954 For more detailed setup instructions, see https://docs.gnunet.org/
1955
1956 Optionally, download and compile gnunet-gtk to get a GUI for
1957 file-sharing and configuration.  This is particularly recommended
1958 if your network setup is non-trivial, as gnunet-setup can be
1959 used to test in the GUI if your network configuration is working.
1960 gnunet-setup should be run as the "gnunet" user under X.  As it
1961 does very little with the network, running it as "root" is likely
1962 also harmless.  You can also run it as a normal user, but then
1963 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1964 home directory in the end.
1965
1966 Once you have configured your peer, run (as the 'gnunet' user)
1967         gnunet-arm -s
1968 to start the peer.  You can then run the various GNUnet-tools as
1969 your "normal" user (who should only be in the group 'gnunet').
