Miek Gieben 885e6e8246 Allow more than 1 address for transfer (#121)
No reason why not to allow more then one address:
`transfer to 127.0.0.1 10.240.20.1`.

Fix startup as well, as it turned out to be broken...

file

file enables serving zone data from a RFC-1035 styled file.

The file middleware is used for "old-style" DNS server. It serves from a preloaded file that exists on disk.

Syntax

file dbfile [zones...]
  • dbfile the database file to read and parse.
  • zones zones it should be authoritative for. If empty the zones from the configuration block are used.

If you want to round robin A and AAAA responses look at the loadbalance middleware.

TSIG key configuration is TODO; directive format for transfer will probably be extended with TSIG key information, something like transfer out [address...] key [name] [base64]

file dbfile [zones... ] {
    transfer from [address...]
    transfer to [address...]

}
  • transfer enables zone transfers. It may be specified multiples times. To or from signals the direction. Addresses must be denoted in CIDR notation (127.0.0.1/32 etc.) or just as plain address. The special wildcard "*" means: the entire internet (only valid for 'transfer to').

Examples

Load the miek.nl zone from miek.nl.signed and allow transfers to the internet.

file miek.nl.signed miek.nl {
    transfer to *
}
