Tutorial: GNUnet on NetBSD 8.0 CURRENT

Welcome to the GNUnet tutorial for NetBSD!

This tutorial provides concrete instructions on how to install a current version of GNUnet. The goal is to support newcomers, either users or developers, who want to get in touch with GNUnet for the first time.

Requirements

As a bare minimum, we recommend you install pkgsrc. This tutorial assumes you have the CURRENT version checked out. Additionally you might want to install devel/git-base and git clone pkgsrc-wip into the wip folder in your pkgsrc folder:

$ cd /usr/pkgsrc
$ git clone git://wip.pkgsrc.org/pkgsrc-wip.git wip

Installer

Note: $ stands for commands run as unprivileged user, # for commands run as root user (this can be done with security/doas, security/sudo, or just as root).

GNUnet is not yet in the pkgsrc tree, it's still in the pkgsrc-wip repository. So if you checked out pkgsrc-wip into /usr/pksrc/wip:

$ cd /usr/pkgsrc/wip/gnunet

Before you start building, you might want to review your /etc/mk.conf. I suggest to consider:

• WRKOBJDIR=/usr/work
• DISTDIR=/usr/distfiles
• DEPENDS_TARGET=package
• UPDATE_TARGET=bin-install
• ACCEPTABLE_LICENSES+=gnu-agpl-v3
• MKREPRO=yes

As we rely on ImageMagick somewhere down our dependency chain (it is one of libextractor's dependencies), you need to set the following (as of 2019-03-06) as well:

• IGNORE_URL+=https://nvd.nist.gov/vuln/detail/CVE-2018-15607

You could however just env ALLOW_VULNERABLE_PACKAGES=1

The build process can involve manual installation interruptions for dependencies!

Then start building:

$ make package

Once you are done, type:

$ make install

or alternatively:

# pkg_add /usr/pkgsrc/packages/All/gnunet-0.11.8.tgz

And you're done!.
GNUnet has a number of services and features. Please check our documentation to learn how to use them. If you find anything odd or bugs, please let us know.

Note that the rc.d file which is installed is not yet fully functional and is getting debugged.

First steps

Congratulations! GNUnet is now installed! Before starting it you may create a configuration file. By default GNUnet looks in our home directory for the file `~/.config/gnunet.conf`. Creating the configuation file is optional. For now just create an empty file which will remind you of the location later if needed:

$ touch ~/.config/gnunet.conf

It's reccomended that you increase your bandwidth restrictions from the acutely low defaults. The example below sets the WAN and LAN limits to the value "unlimited".

GNUnet and its services are managed using the command line tool `gnunet-arm` (Automatic Restart Manager).
To start GNUnet with its default services execute:

$ gnunet-arm -s

To list the running services use:

$ gnunet-arm -I
Running services:
ats (gnunet-service-ats)
revocation (gnunet-service-revocation)
set (gnunet-service-set)
nat (gnunet-service-nat)
transport (gnunet-service-transport)
peerstore (gnunet-service-peerstore)
hostlist (gnunet-daemon-hostlist)
identity (gnunet-service-identity)
namecache (gnunet-service-namecache)
peerinfo (gnunet-service-peerinfo)
datastore (gnunet-service-datastore)
zonemaster (gnunet-service-zonemaster)
zonemaster-monitor (gnunet-service-zonemaster-monitor)
nse (gnunet-service-nse)
cadet (gnunet-service-cadet)
dht (gnunet-service-dht)
core (gnunet-service-core)
gns (gnunet-service-gns)
statistics (gnunet-service-statistics)
topology (gnunet-daemon-topology)
fs (gnunet-service-fs)
namestore (gnunet-service-namestore)
vpn (gnunet-service-vpn)

To stop all services, use the `-e` option.

$ gnunet-arm -e

Alternative: Installation from source

The following instructions are only really interesting for developers or if you need special build switches. First, install the dependencies from pkgsrc. You can use binary built packages, but since we are using CURRENT of pkgsrc, this is more direct. For the binary built version, use pkg_add or pkgin (and read into pkgsrc CURRENT with pkgin or pkg_add).

• audio/libopus
• databases/sqlite3
• devel/gettext-lib (maybe?)
• devel/gmp
• devel/nss
• devel/zlib
• devel/libgsf
• devel/libltdl
• devel/git-base
• devel/autoconf
• devel/automake
• devel/libtool
• devel/pkgconf (required for some of the dependencies, not GNUnet)
• devel/libffi
• devel/libidn2
• devel/libextractor
• lang/python37 (for the testsuite)
• math/glpk (only for experimental features)
• multimedia/gstreamer1
• multimedia/gst-plugins1-base
• multimedia/libogg
• textproc/jansson
• textproc/libunistring
• security/libgcrypt
• security/gnutls
• www/gnurl
• www/libmicrohttpd

Code Source

$ cd ~
$ git clone https://gnunet.org/git/gnunet.git ~/src/gnunet/gnunet

Compile and Install

You have a choice between two options:

• build the production version

or

• build the development version.

If you want to start writing GNUnet applications or join the GNUnet development choose the development version (it will print more debug output and contains debug symbols that can be displayed with a debugger). Otherwise choose the production version.

Option 1: GNUnet for production / usage

We are assuming a shell and environment which exports $HOME. If $HOME is not exported, do so or replace $HOME accordingly in the instructions given below.

$ cd ~/src/gnunet/gnunet
$ sh ./bootstrap
$ LDFLAGS=-L/usr/pkg/lib ./configure --prefix=$HOME/gnunet

After configure passes, you need to add a 'gnunetdns' group to your system. Further, you need to add a user 'gnunet' which is part of the group 'gnunet'. Then:

$ make
# make install

Option 2: GNUnet experimental

Perform the same steps as for Option 1, but add the configure switch --enable-experimental. For even more verbosity you could configure gnunet like this:

$ LDFLAGS="-L/usr/pkg/lib -L/usr/X11R7/lib -Wl,-R/usr/X11R7/lib" CFLAGS="-g -O0" ./configure --prefix=$HOME/gnunet --enable-logging=verbose

This allows you to get more verbose logs when you export GNUNET_FORCE_LOG=";;;;DEBUG" before you run tests.
