strongSwan

h1. PT-TLS SWIMA Client

h2. Installing the strongSwan TNC Software

First we have to install some additional Ubuntu packages needed for the strongSwan TNC build
<pre>
sudo apt install libssl-dev libcurl4-openssl-dev sqlite3 libsqlite3-dev libjson0-dev
</pre>

Download the lastest strongSwan tarball
<pre>
wget https://download.strongswan.org/strongswan-5.6.0dr1.tar.bz2
</pre>

Unpack the tarball
<pre>
tar xf strongswan-5.6.0dr1.tar.bz2
</pre>

and change into the strongSwan build directory
<pre>
cd strongswan-5.6.0dr1
</pre>

Configure strongSwan with the following options
<pre>
./configure --prefix=/usr --sysconfdir=/etc --disable-gmp --enable-openssl --enable-tnc-imc --enable-tnccs-20 --enable-imc-os --enable-imc-swima --enable-sqlite --enable-curl
</pre>

Build and install strongSwan with the commands
<pre>
make; sudo make install
</pre>

h2. Configure the strongSwan "sw-collector" Tool

The *sw-collector* tool allows all software installation events to be collected and stored in an SQLite database. First we set up a clean collector database with the command
<pre>
sudo -s
mkdir /etc/pts
cat /usr/share/strongswan/templates/database/sw-collector/sw_collector_tables.sql | sqlite3 /etc/pts/collector.db
</pre>

The *sw-collector* needs some options defined in the */etc/strongswan.conf*/ configuration file
<pre>
sw-collector {
database = sqlite:///etc/pts/collector.db
history = /var/log/apt/history.log
first_time = 2017-02-15T20:20:34Z
rest_api {
uri = https://admin-user:ietf99hackathon@tnc.example/api/
}
}
</pre>

The date of the original OS installation can be found e.g. with the command
<pre>
ls -l --full-time /var/log/bootstrap.log
-rw-r--r-- 1 root root 57457 2017-02-15 12:20:34.000000000 -0800 /var/log/bootstrap.log
</pre>
