2291 Please make sure NOW that you have created a user and group 'gnunet'
2292 and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux,
2296 adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
2298 Make sure that '/var/lib/gnunet' is owned (and writable) by user
2299 'gnunet'. Then, you can compile GNUnet with
2303 After that, run (if necessary as 'root')
2307 to install everything.
2309 Each GNUnet user should be added to the 'gnunet' group (may
2310 require fresh login to come into effect):
2312 adduser USERNAME gnunet
2314 (run the above command as root once for each of your users, replacing
2315 "USERNAME" with the respective login names). If you have a global IP
2316 address, no further configuration is required.
2318 For more detailed setup instructions, see https://docs.gnunet.org/
2320 Optionally, download and compile gnunet-gtk to get a GUI for
2321 file-sharing and configuration. This is particularly recommended
2322 if your network setup is non-trivial, as gnunet-setup can be
2323 used to test in the GUI if your network configuration is working.
2324 gnunet-setup should be run as the "gnunet" user under X. As it
2325 does very little with the network, running it as "root" is likely
2326 also harmless. You can also run it as a normal user, but then
2327 you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
2328 home directory in the end.
2330 Once you have configured your peer, run (as the 'gnunet' user)
2334 to start the peer. You can then run the various GNUnet-tools as
2335 your "normal" user (who should only be in the group 'gnunet').
