1647 Please make sure NOW that you have created a user and group 'gnunet'

1649         addgroup gnunetdns
1650         adduser gnunet
1651
1652 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1653 'gnunet'.  Then, you can compile GNUnet with
1654         make
1655
1656 After that, run (if necessary as 'root')
1657         make install
1658 to install everything.
1659
1660 Each GNUnet user should be added to the 'gnunet' group (may
1661 require fresh login to come into effect):
1662         adduser USERNAME gnunet
1663 (run the above command as root once for each of your users, replacing
1664 "USERNAME" with the respective login names).  If you have a global IP
1665 address, no further configuration is required.
1666
1667 Optionally, download and compile gnunet-gtk to get a GUI for
1668 file-sharing and configuration.  This is particularly recommended
1669 if your network setup is non-trivial, as gnunet-setup can be
1670 used to test in the GUI if your network configuration is working.
1671 gnunet-setup should be run as the "gnunet" user under X.  As it
1672 does very little with the network, running it as "root" is likely
1673 also harmless.  You can also run it as a normal user, but then
1674 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1675 home directory in the end.
1676
1677 Once you have configured your peer, run (as the 'gnunet' user)
1678         gnunet-arm -s
1679 to start the peer.  You can then run the various GNUnet-tools as
1680 your "normal" user (who should only be in the group 'gnunet').
