Class | Dnsruby::ZoneTransfer |
In: |
lib/Dnsruby/zone_transfer.rb
|
Parent: | Object |
This class performs zone transfers as per RFC1034 (AXFR) and RFC1995 (IXFR).
klass | [RW] | The class - defaults to IN |
last_tsigstate | [R] | Returns the tsigstate of the last transfer (nil if no TSIG signed transfer has occurred) |
port | [RW] | The port to connect to - defaults to 53 |
serial | [RW] | If using IXFR, this is the SOA serial number to start the incrementals from |
server | [RW] | The nameserver to use for the zone transfer - defaults to system config |
transfer_type | [RW] | What type of transfer to do (IXFR or AXFR) - defaults to AXFR |
tsig | [R] | The TSIG record used to sign the transfer |
Compare two serials according to RFC 1982. Return 0 if equal, -1 if s1 is bigger, 1 if s1 is smaller.
Perform a zone transfer (RFC1995) If an IXFR query is unsuccessful, then AXFR is tried (and @transfer_type is set to AXFR) TCP is used as the only transport
If AXFR is performed, then the zone will be returned as a set of records :
zt = Dnsruby::ZoneTransfer.new zt.transfer_type = Dnsruby::Types.AXFR zt.server = "ns0.validation-test-servers.nominet.org.uk" zone = zt.transfer("validation-test-servers.nominet.org.uk") soa = zone[0] rec1 = zone[1] print zone.to_s
If IXFR is performed, then the incrementals will be returned as a set of Deltas. Each Delta contains the start and end SOA serial number, as well as an array of adds and deletes that occurred between the start and end.
zt = Dnsruby::ZoneTransfer.new zt.transfer_type = Dnsruby::Types.IXFR zt.server = "ns0.validation-test-servers.nominet.org.uk" zt.serial = 2007090401 deltas = zt.transfer("validation-test-servers.nominet.org.uk") assert_equal("Should show up in transfer", deltas[0].adds[1].data)
Sets the TSIG to sign the zone transfer with. Pass in either a Dnsruby::RR::TSIG, or a key_name and key (or just a key) Pass in nil to stop tsig signing.
