1956 IMPORTANT:
1957
1958 Please make sure NOW that you have created a user and group 'gnunet'
1959 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
1960 type:
1961
1962   addgroup gnunetdns
1963   adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1964
1965 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1966 'gnunet'.  Then, you can compile GNUnet with
1967
1968   make
1969
1970 After that, run (if necessary as 'root')
1971
1972   make install
1973
1974 to install everything.
1975
1976 Each GNUnet user should be added to the 'gnunet' group (may
1977 require fresh login to come into effect):
1978
1979   adduser USERNAME gnunet
1980
1981 (run the above command as root once for each of your users, replacing
1982 "USERNAME" with the respective login names).  If you have a global IP
1983 address, no further configuration is required.
1984
1985 For more detailed setup instructions, see https://docs.gnunet.org/
1986
1987 Optionally, download and compile gnunet-gtk to get a GUI for
1988 file-sharing and configuration.  This is particularly recommended
1989 if your network setup is non-trivial, as gnunet-setup can be
1990 used to test in the GUI if your network configuration is working.
1991 gnunet-setup should be run as the "gnunet" user under X.  As it
1992 does very little with the network, running it as "root" is likely
1993 also harmless.  You can also run it as a normal user, but then
1994 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1995 home directory in the end.
1996
1997 Once you have configured your peer, run (as the 'gnunet' user)
1998
1999   gnunet-arm -s
2000
2001 to start the peer.  You can then run the various GNUnet-tools as
2002 your "normal" user (who should only be in the group 'gnunet').
