h2. Configuring a PT-TLS SWIMA Client

The following [[SwimaClient|HOWTO]] describes the installation and configuration of a PT-TLS-based SW Client on an Ubuntu 16.04 platform.

h2. Configuring a PT-TLS SWIMA Server

The following [[SwimaServer|HOWTO]] describes the installation and configuration of a PT-TLS-based Server Daemon on an Ubuntu 16.04 platform.

h2. Starting PT-TLS Server Daemon

The PT-TLS server based on the strongSwan systemd daemon is usually started automatically at boot time with the command

<pre>

systemctl start strongswan-swanctl

</pre>

First all the PA-TNC attribute definitions from the IETF, TCG, ITA-HSR and PWG namespaces are loaded. The IMVs to by dynamically loaded are read from _/etc/tnc_config_.

Multiple PT-TLS server and CA certificates are loaded into the daemon

<pre>

Jun 22 12:31:28 koala charon-systemd[12088]: loaded certificate 'C=CH, O=MSE, OU=TSM_ITSec, CN=MSE CA'

</pre>

The actual loading is done by the *swanctl* command line tool which transfers the certificates to the daemon via a Unix socket.

Again it is the *swanctl* tool which loads the private keys or determines the IDs of keys residing on smartcard or TPM devices.

<pre>
