====== Stellar Wireless DSPSK via OmniVista UPAM Radius Proxy zu externem Radius Server ======

In diesem Artikel wird beschrieben wie Stellar Wireless gerätespezifische Pre-Shared-Keys (Stellar DSPSKs) von einem externen Radius Server verwenden kann. Dabei verwendet der Nutzer einen ihm/dem Gerät zugewiesenen PSK und dieser wird auch in dieser Form im externen Radius hinterlegt (in diesem Fall ist dies kein Eintrag in "OmniVista: Company Property").

<WRAP center round tip 60%>
In OmniVista v4.5R2 kann die Funktion wie hier beschrieben nur dann verwendet werden, wenn **Authenticated Switch Access** in UPAM nicht verwendet wird.
</WRAP>


===== Aufbau / Zeichnung =====
{{ ::ale-stellar-wlan-dspsk-omnivista-upam-external-radius.png?direct |}}

===== Konfiguration des externen Radius Servers (freeradius 3.0) =====
Wir beginnen mit der Konfiguration des externen Radius Servers, in diesem Fall ein freeradius 3.0 auf Debian Buster 10.5.
==== freeradius 3.0 - clients.conf ====
Entsprechend die Freigabe für die Abfrage Stellar AP -> OmniVista UPAM Proxy -> Externer Radius Server einrichten.
<code>
sudo vi /etc/freeradius/3.0/clients.conf 

# IP Subnetz/Host von OmniVista 2500 UPAM
client stellar-ext-radius {
        ipaddr          = 192.168.2.0/24
        secret          = ext-radius-2020
}
</code>

==== freeradius 3.0 - dictionary.xylan ====
Damit wir das "ALE-Stellar-DSPSK"-Attribut verwenden können, müssen wir dieses dem freeradius bekanntmachen.
Je nach Distribution kann der Pfad abweichen. 
<code>
sudo vi /usr/share/freeradius/dictionary.xylan

# Eintrag nach Xylan-Acce-Priv-F-W2 einfuegen:
ATTRIBUTE       ALE-Stellar-DSPSK                       155     string

</code>

==== freeradius 3.0 - users ====
Wenn es sich um eine neue freeradius Installation handelt, können je nach Distribution und mitgelieferter Konfiguration noch ein paar DEFAULT-Einträge in der users-Datei sein. Diese sollte man natürlich im Hinterkopf haben, damit der Access-Request auch bis zum Benutzer (MAC-ADDR) ankommt.
<code>
sudo vi /etc/freeradius/3.0/users

# Je nachdem was fuer ein Format gewaehlt wurde oder
# via OmniVista -> WLAN -> SSIDs -> (DSPSK-SSID) -> Advanced AAA Configuration
# festgelegt wurde.
# Im externen Radius ist der PSK im Cleartext-Format hinterlegt.
# Das PSK fuer das Endgeraet f0:c3:71:2e:fd:8d ist also "VuPmjRhbArWmvzPRZCThHgnf".
# Mit der Filter-Id koennte man das UNP der SSID uebersteuern um z.B. Mbps Limits festzulegen
# Achtung: Diese UNPs muessen natuerlich vorher auf die AP-Gruppe ausgerollt werden!
#
# Typisch waeren standardmaeszig GROSSSCHREIBUNG und keine Trennzeichen
#F0C3712EFD8D    Cleartext-Password := "F0C3712EFD8D"
# Mein Beispiel verwendet aber ein anderes Format:
f0:c3:71:2e:fd:8d       Cleartext-Password := "f0c3712efd8d"
                # Cleartext: VuPmjRhbArWmvzPRZCThHgnf
                ALE-Stellar-DSPSK = "VuPmjRhbArWmvzPRZCThHgnf"
                #Filter-Id = "dspsk1mbps"

</code>

==== freeradius 3.0 - Debug-Log-Ausgabe ====
Passend dazu auch das Wireshark PCAPNG: {{ ::dspsk3.pcapng.zip |}}
Radius Shared Secret zwischen OmniVista UPAM und dem externen freeradius 3.0 ist **ext-radius-2020**

===== Konfiguration für Stellar Wireless / OmniVista =====

==== Einrichtung der Stellar Wireless DSPSK SSID ====
Wichtig ist in diesem Schritt den OmniVista UPAM Radius Eintrag auszuwählen, damit die Stellar Wireless APs sich an OmniVista UPAM und nicht direkt an den Radius wenden. Die Konfiguration kann bereits auf die gewünschte AP-Gruppe ausgerollt werden!
{{ ::dspsk-1.png?direct |}}
=== Optional: Granulare Konfiguration der "Advanced AAA Configuration"  ===
Hier kann wahlweise das Format für die Anfrage am RADIUS festgelegt werden. OV 4.5R2 (>= Build 63) wird den Access-Request entsprechend durchleiten.
{{ ::dspsk-4.png?direct |}}
==== Externen Radius-Server anlegen ====
Dies ist der externe Radius-Server mit einem eigenen Radius Shared Secret (hier sollte man von meinem Beispiel "ext-radius-2020" abweichen)!
{{ ::dspsk-2.png?direct |}}
==== Bestehende "Authentication Strategy" editieren ====
Die bereits im Rahmen der SSID-Erzeugung angelegte **Authentication Strategy** ändert man nun von **Local Database** auf den soeben angelegten **External Radius**.
{{ ::dspsk-3.png?direct |}}

===== Prüfen der Installation =====
==== OmniVista: Client List ====
Hier wird der Client angezeigt, auch mit dem Hinweis auf DSPSK.
{{ ::dspsk-5.png?direct |}}

==== Wireshark zur Analyse der RADIUS-Kommunikation ====
Wireshark Capture meines Laboraufbaus: {{ ::dspsk3.pcapng.zip |}} (Radius Shared Secret: ext-radius-2020)
Im folgenden Screenshot wird gezeigt über welches Menü man den Key in Wireshark hinterlegen kann.
