Hallo! Ich habe mich die letzten 2 Tage dran gesetzt und einen dhcp eingerichtet. Dieser funktioniert auch soweit, dass die Clienten die nötigen Daten (IP, Gateway, DNS) bekommen. Was nicht funktioniert ist die Weitergabe der frisch erteilten IP-Adresse mit dem Hostnamen an den DNS, d.h. es ist nicht möglich den Namen aufzulösen. Folgende Meldungen / Einträge kann ich anbieten: ---/etc/dhcpd.conf--- # Allgemein gültige Einträge option domain-name-servers 192.168.100.1; option routers 192.168.100.1; # Dynmaischer Update DNS, verwende sicheres Schema ddns-update-style interim;
