  1872. Please make sure NOW that you have created a user and group 'gnunet'
  1873. and additionally a group 'gnunetdns'. On Debian and Ubuntu GNU/Linux, type:
  1874. addgroup gnunetdns
  1875. adduser --system --group --disabled-login --home /var/lib/gnunet gnunet
  1876. Make sure that '/var/lib/gnunet' is owned (and writable) by user
  1877. 'gnunet'. Then, you can compile GNUnet with
  1878. make
  1879. After that, run (if necessary as 'root')
  1880. make install
  1881. to install everything.
  1882. Each GNUnet user should be added to the 'gnunet' group (may
  1883. require fresh login to come into effect):
  1884. adduser USERNAME gnunet
  1885. (run the above command as root once for each of your users, replacing
  1886. "USERNAME" with the respective login names). If you have a global IP
  1887. address, no further configuration is required.
  1888. For more detailed setup instructions, see https://docs.gnunet.org/
  1889. Optionally, download and compile gnunet-gtk to get a GUI for
  1890. file-sharing and configuration. This is particularly recommended
  1891. if your network setup is non-trivial, as gnunet-setup can be
  1892. used to test in the GUI if your network configuration is working.
  1893. gnunet-setup should be run as the "gnunet" user under X. As it
  1894. does very little with the network, running it as "root" is likely
  1895. also harmless. You can also run it as a normal user, but then
  1896. you have to copy ~/.gnunet/gnunet.conf" over to the "gnunet" user's
  1897. home directory in the end.
  1898. Once you have configured your peer, run (as the 'gnunet' user)
  1899. gnunet-arm -s
  1900. to start the peer. You can then run the various GNUnet-tools as
  1901. your "normal" user (who should only be in the group 'gnunet').
