1985 Please make sure NOW that you have created a user and group 'gnunet'
1986 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
1987         addgroup gnunetdns
1988         adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
1989
1990 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1991 'gnunet'.  Then, you can compile GNUnet with
1992         make
1993
1994 After that, run (if necessary as 'root')
1995         make install
1996 to install everything.
1997
1998 Each GNUnet user should be added to the 'gnunet' group (may
1999 require fresh login to come into effect):
2000         adduser USERNAME gnunet
2001 (run the above command as root once for each of your users, replacing
2002 "USERNAME" with the respective login names).  If you have a global IP
2003 address, no further configuration is required.
2004
2005 For more detailed setup instructions, see https://gnunet.org/installation
2006
2007 Optionally, download and compile gnunet-gtk to get a GUI for
2008 file-sharing and configuration.  This is particularly recommended
2009 if your network setup is non-trivial, as gnunet-setup can be
2010 used to test in the GUI if your network configuration is working.
2011 gnunet-setup should be run as the "gnunet" user under X.  As it
2012 does very little with the network, running it as "root" is likely
2013 also harmless.  You can also run it as a normal user, but then
2014 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2015 home directory in the end.
2016
2017 Once you have configured your peer, run (as the 'gnunet' user)
2018         gnunet-arm -s
2019 to start the peer.  You can then run the various GNUnet-tools as
2020 your "normal" user (who should only be in the group 'gnunet').
