1620 Please make sure NOW that you have created a user and group 'gnunet'
1621 and additionally a group 'gnunetdns':
1622         addgroup gnunetdns
1623         adduser gnunet
1624
1625 Make sure that '/var/lib/gnunet' is owned (and writable) by user
1626 'gnunet'.  Then, you can compile GNUnet with
1627         make
1628
1629 After that, run (if necessary as 'root')
1630         make install
1631 to install everything.
1632
1633 Each GNUnet user should be added to the 'gnunet' group (may
1634 require fresh login to come into effect):
1635         adduser USERNAME gnunet
1636 (run the above command as root once for each of your users, replacing
1637 "USERNAME" with the respective login names).  If you have a global IP
1638 address, no further configuration is required.
1639
1640 Optionally, download and compile gnunet-gtk to get a GUI for
1641 file-sharing and configuration.  This is particularly recommended
1642 if your network setup is non-trivial, as gnunet-setup can be
1643 used to test in the GUI if your network configuration is working.
1644 gnunet-setup should be run as the "gnunet" user under X.  As it
1645 does very little with the network, running it as "root" is likely
1646 also harmless.  You can also run it as a normal user, but then
1647 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
1648 home directory in the end.
1649
1650 Once you have configured your peer, run (as the 'gnunet' user)
1651         gnunet-arm -s
1652 to start the peer.  You can then run the various GNUnet-tools as
1653 your "normal" user (who should only be in the group 'gnunet').
