[Solved] Using avahi to publish IPV6 DNSservers - Security?
we use here internal avahi to publish IPV6 DNSservers. It was the easiest way for us to use the service with radvd. Here is the part from the avahiconf: publish-dns-servers=IPV6adress-dns-server
This works really fine. But my problem is the security. When you have this config for example in an public locaten. Some go here and broadcast his own dnsserver.
There is some file "/etc/mdns.allow". Here can you set domainnames. But this is only "from this client". For example: "tux.at"
When this is set, only client in the avahi-domain "tux.at" are dissolvable.
But what I would like to know is, is there a place on the client where i can set the IPadress of the server that is allowed to publish his dnsservers?
