Wie man sieht, funktioniert auch schon der Befehl route add -host 255.255.255.255 dev eth0 nicht richtig. Also stelle ich wieder auf statische Adressen zurück.

Aber dies könnte auch eine neue Aufgabenstellung werden für unsere embedded-linux-community!

Nach der Umstellung zurück auf die statischen Adressen funktioniert der QADC-Test auf Anhieb.

Jetzt lautet die Browseradresse: http://192.168.178.11/cgi-bin/cgi_qadc

Hostnamen funktionieren ebenfalls grundsätzlich nicht. Könnte auch noch ein weiteres Betätigungsfeld werden.
