I am working on my bsc thesis which talks about the dnsbased authentication of named entities dane in order to set up dane records, i first need to set. The name, algorithm, size, and type of the key will be set to match the existing key. Auto dnssec bind sonstige anwendungen netcup kundenforum. The effect of this option is therefore the same as the effect of including the rndc sign command in a cron job, in combination with the autodnssec allow option. As in the first post about dnssec signing, dnssec keygen is used to create the keys. Newer bind versions or other dns software have greatly simplified dnssec signing.
In earlier versions of bind, you had to use the dnssecsignzone utility to sign your zone. Both signed and unsigned responses can be validated when dnssec is enabled. This is an introductory howto to get dnssec running with bind. The command line interface tool dnsseckeygen provides the 3 option. Using remote name daemon control rndc, we can then apply the updated config done above, and load the keys from the given directory. The key size does not need to be specified if using a default algorithm. The ds records are supposed to be given to your domain registrar, and they are the ones who are supposed to publish them. Dnssec signing your domain with bind inline signing.
The first dnsseckeygen command creates the ksk with a key size of 2,048 bits using the rsasha256 dnssec algorithm. By default, dnseckeygen uses devrandom the generation is slow, so much more in less busy systems. Einen eigenen key erzeugen sie mit dem befehl dnsseckeygen. Create rndc key and configuration file first step is to create rndc key file and configuration file. If this option is used and no algorithm is explicitly set on the command line, nsec3rsasha1 will be used by default. Use an nsec3capable algorithm to generate a dnssec key. For compatibility reasons, it it is still the default. Deploying dnssec with bind and ubuntu server apnic. I have a working zone for that works properly various tests report success, such as the one on s dns. With autodnssec, it is very easy to automate the rollover of zsk pairs, simply by periodically putting the new keys in the key directory using the dnsseckeygen s i command. Dsa keys must be between 512 and 1024 bits and an exact multiple of 64.
