Hallo Versuche seit einigen Tage DHCP mit DDNS zum laufen zu bringen. Funktioniert auch alles bis auf die Tatsache dass die reverse Zone nicht aktualisiert wird. Im log steht: May 3 20:11:20 testserver dhcpd: if nbook.localnet.lan IN TXT "316dfa7d57ebc6d3e3d5a5587cfcf6d30c" rrset exists and nbook.localnet.lan IN A 192.168.1.67 rrset exists delete nbook.localnet.lan IN A 192.168.1.67: success.
