2081 Please make sure NOW that you have created a user and group 'gnunet'
2082 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2086 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2088 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2089 'gnunet'. Then, you can compile GNUnet with
2093 After that, run (if necessary as 'root')
2097 to install everything.
2099 Each GNUnet user should be added to the 'gnunet' group (may
2100 require fresh login to come into effect):
2102 adduser USERNAME gnunet
2104 (run the above command as root once for each of your users, replacing
2105 "USERNAME" with the respective login names). If you have a global IP
2106 address, no further configuration is required.
2108 For more detailed setup instructions, see https://docs.gnunet.org/
2110 Optionally, download and compile gnunet-gtk to get a GUI for
2111 file-sharing and configuration. This is particularly recommended
2112 if your network setup is non-trivial, as gnunet-setup can be
2113 used to test in the GUI if your network configuration is working.
2114 gnunet-setup should be run as the "gnunet" user under X. As it
2115 does very little with the network, running it as "root" is likely
2116 also harmless. You can also run it as a normal user, but then
2117 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2118 home directory in the end.
2120 Once you have configured your peer, run (as the 'gnunet' user)
2124 to start the peer. You can then run the various GNUnet-tools as
2125 your "normal" user (who should only be in the group 'gnunet').
