Dependencies:
=============
-For the impatient, here is the list of immediate dependencies for
-running GNUnet:
+Please note that for many of its dependencies GNUnet requires very
+recent versions of the libraries which are often NOT to be found in
+stable distributions in 2011. While using older packages may in some
+cases on some operating systems may seem to work in some limited
+fashion, we are in many cases aware of serious problems with older
+packages. Hence please make sure to use the versions listed below.
+
+These are the direct dependencies for running GNUnet:
- libextractor >= 0.6.1
-- libmicrohttpd >= 0.4.6
+- libmicrohttpd >= 0.9.18
- libgcrypt >= 1.2
-- libgmp >= 4.0
-- libcurl >= 7.15.4
+- libcurl >= 7.21.0
+- libunistring >= 0.9.2
- libltdl >= 2.2 (part of GNU libtool)
-- sqlite >= 3.0 (alternative to MySQL)
-- mysql >= ??? (not yet supported)
-- postgres >= ??? (not yet supported)
+- sqlite >= 3.0 (default database)
+- mysql >= 5.1 (alternative to sqLite)
+- postgres >= 8.3 (alternative to sqLite)
Recommended autotools for compiling the SVN version are:
- autoconf >= 2.59
- automake >= 1.11.1
- libtool >= 2.2
-See also README.debian for a list of Debian packages.

How to install?
===============
system. For a more detailed description, read the installation
instructions on the webpage at https://gnunet.org/installation.
+Note that some functions of GNUnet require "root" access. GNUnet will
+install (tiny) SUID binaries for those functions is you run "make
+install" as root. If you do not, GNUnet will still work, but some
+functionality will not be available (including certain forms of NAT
+traversal).
+
GNUnet requires the GNU MP library (http://www.gnu.org/software/gmp/)
and libgcrypt (http://www.gnupg.org/). You can specify the path to
libgcrypt by passing "--with-gcrypt=PATH" to configure. You will also
-need either sqlite (http://www.sqlite.org/) or MySQL

+need either sqlite (http://www.sqlite.org/), MySQL
+(http://www.mysql.org/) or PostGres (http://www.postgres.org/).
If you install from source, you need to install GNU libextractor first
(download from http://www.gnu.org/software/libextractor/). We also
recommend installing GNU libmicrohttpd (download from
http://www.gnu.org/software/libmicrohttpd/). Then you can start the
-actual GNUnet compilation process with:
+actual GNUnet compilation and installation process with:
-$ ./configure --prefix=$HOME --with-extractor=$HOME
+$ export GNUNET_PREFIX=/usr/local # or other directory of your choice
+$ addgroup gnunetdns
+$ adduser gnunet gnunet
+$ ./configure --prefix=$GNUNET_PREFIX --with-extractor=$LE_PREFIX
$ make
# make install
# sudo -u gnunet mkdir ~/.gnunet/
# sudo -u gnunet touch ~/.gnunet/gnunet.conf
# sudo -u gnunet gnunet-arm -s
-This will compile and install GNUnet to $HOME/bin/, $HOME/lib/ and
-$HOME/share/ and start the system with the default configuration. It
-is recommended that you add a user "gnunet" to run "gnunet-arm". You
-can then still run the end-user applications as another user. If you
-create a user "gnunet", it is recommended that you edit the
-configuration file slightly so that data can be stored in
-"/var/lib/gnunet"; you may also want to use "/etc/gnunet.conf" for the
-location of the configuration file in this case.
-
-Note that additional, per-user configuration files
-(~/.gnunet/gnunet.conf) need to be created by each user (for example,
-by running gnunet-setup). For more general information about the GNU
-build process read the INSTALL file.
-
-If you are compiling the code from subversion, you have to run
-". bootstrap" before ./configure. If you receive an error during the
-running of ". bootstrap" that looks like "macro `AM_PATH_GTK' not
+This will create the users and groups needed for running GNUnet
+securely and then compile and install GNUnet to $GNUNET_PREFIX/bin/,
+$GNUNET_PREFIX/lib/ and $GNUNET_PREFIX/share/ and start the system
+with the default configuration. It is strongly recommended that you
+add a user "gnunet" to run "gnunet-arm". You can then still run the
+end-user applications as another user.
+
+If you create a system user "gnunet", it is recommended that you edit
+the configuration file slightly so that data can be stored in the
+system user home directory at "/var/lib/gnunet"; you may also want to
+use "/etc/gnunet.conf" for the location of the configuration file in
+this case.
+
+You can avoid running 'make install' as root if you run configure
+with the "--with-sudo=yes" option and have extensive sudo rights
+(can run "chmod +s" and "chown" via 'sudo'). If you run 'make install'
+as a normal user without sudo rights (or the configure option),
+certain binaries that require additional priviledges will not be
+installed properly (and autonomous NAT traversal, WLAN, DNS/GNS and
+the VPN will then not work).
+
+If you run 'configure' and 'make install' as root or use the SUDO
+option, GNUnet's build system will install "libnss_gns*" libraries to
+"/lib/" regardless (!) of the $GNUNET_PREFIX you might have specified,
+as those libraries must be in "/lib/". If you are packaging GNUnet
+for binary distribution, this may cause your packaging script to miss
+those plugins, so you might need to do some additional manual work to
+include those libraries in your binary package(s). Similarly, if you
+want to use the GNUnet naming system and did NOT run GNUnet's 'make
+install' process with SUDO rights, the libraries will be installed to
+"$GNUNET_PREFIX/lib" and you will have to move them to "/lib/"
+manually.
+
+Finally, if you are compiling the code from subversion, you have to
+run ". bootstrap" before ./configure. If you receive an error during
+the running of ". bootstrap" that looks like "macro `AM_PATH_GTK' not
found in library", you may need to run aclocal by hand with the -I
option, pointing to your aclocal m4 macros, i.e.
Configuration
=============
+Note that additional, per-user configuration files
+(~/.gnunet/gnunet.conf) need to be created by each user (for example,
+by running gnunet-setup). Note that gnunet-setup is a separate
+download and requires recent versions of GTK+ and Glade; you can also
+edit the configuration file by hand, but this is not recommended. For
+more general information about the GNU build process read the INSTALL
+file.
+
GNUnet uses two types of configuration files, one that specifies the
-system-wide defaults (typically located in /usr/share/gnunet/defaults
-.conf) and a second one that overrides default values with
-user-specific preferences. The user-specific configuration file
-should be located in "~/.gnunet/gnunet.conf" or its location can be
-specified by giving the "-c" option to the respective GNUnet
-application.

you may want to adjust the limitations (space consumption, bandwidth,

-Running http on port 80
-=======================
+Running http on port 80 and https on port 443
+=============================================
-In order to hide GNUnet's HTTP traffic perfectly, you might consider
-running GNUnet's HTTP transport on port 80. However, we do not
-recommend running GNUnet as root. Instead, forward port 80 to say
-8080 with this command (as root, in your startup scripts):
+In order to hide GNUnet's HTTP/HTTPS traffic perfectly, you might
+consider running GNUnet's HTTP/HTTPS transport on port 80/443.
+However, we do not recommend running GNUnet as root. Instead, forward
+port 80 to say 1080 with this command (as root, in your startup
+scripts):
-# iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 8080
+# iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 1080
-Then set in the HTTP section of gnunet.conf the "ADVERTISED-PORT"
-to "80" and "PORT" to 8080. You can do the same trick for the
-TCP and UDP transports if you want to map them to a priviledged
-port (from the point of view of the network).

-==========================

-// NOTE: SMTP is not currently available in this version of GNUnet
-Running GNUnet over SMTP (e-mail) is a bit more involved. Note that
-you do not need to run all transports (only running the NAT transport
-is the only thing that will not work). If you really want to do
