Miek Gieben 225cdd1ca3 Add AXFR test
Test shouldTransfer by upping a testserver and sending the SOA query.

Remove state from DefaultErrorHandler and just get it from the request.

Add more logging to show what is going on.



This also adds the infrastructure for future tests.

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 out [address...]
    transfer to [address]
}
  • transfer enables zone transfers. It may be specified multiples times. To or from signals the direction. Address must be denoted in CIDR notation (127.0.0.1/32 etc.). The special wildcard "*" means: the entire internet.

Examples

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

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