lantins / dns-zone Goto Github PK

You should be able to start using the lib after scanning the README.md file or looking at the yard generated documentation available at http://www.rubydoc.info/gems/dns-zone/

Even basic methods like dump are not documented.

I opened some pull requests two months ago, no reaction yet. Last commit almost 3 years ago.

So, is this project abandoned? New maintainer needed? @lantins

I'd like to avoid forking and publishing under a different name on Rubygems. But I don't see much other options when I need some fixes or features. (Note that specifying a Github repo as dependency is not possible in a gemspec file.)

Updating the SOA in the example does not actually work!

zone.soa.nameserver = 'ns0.lividpenguin.com.'

The SOA is just another RR and is treated the same, the exception is it must be the first RR and you can only have one of them.

So the 'short hand' syntax makes sense, this should be supported.

Hi, i have problem with loading MX records, where server si not domain name, but just "mail".
For example:

                        MX      10 mail               
mail                    A       some_ip

It's valid record, but you don't load it because you expect full domain name like mail.example.com.

It appears that zonefiles that use lowercase class and RR type keywords are causing DNS::Zone.load to choke and throw an exception:

#! /usr/bin/ruby
require('rubygems')
require('dns/zone')

zdata = <<EOT
$ttl 3600
$origin dnszone.example.com.
@               in soa      ns1.example.com. hostmaster.dnszone.example.com. (
                            2012052400  ; serial
                            345600      ; refresh
                            3600        ; retry
                            604800      ; expire
                            3600        ; ttl
)
EOT

DNS::Zone.load(zdata)
=> RuntimeError: Unknown or unsupported RR Type
	from /usr/local/share/gems/gems/dns-zone-0.3.1/lib/dns/zone/rr.rb:56:in `load'
	from /usr/local/share/gems/gems/dns-zone-0.3.1/lib/dns/zone.rb:105:in `block in load'

	from /usr/local/share/gems/gems/dns-zone-0.3.1/lib/dns/zone.rb:91:in `load'

There is no requirement that the keywords be uppercase.

I'll see if I can work up a patch for this.

This is handy when the zone file does not contain an $ORIGIN directive.

Zone files with more than one $ORIGIN will produce incorrect (repeating) labels for records with later $ORIGINs that don't explicitly set their name to either '@' or some other name.

For example:

$ORIGIN example.com.
@   3600    SOA     ns1.example.com. (
                        hostmaster.example.com.
                        42
                        3600
                        600
                        86400
                        300
                        )

$ORIGIN sub.example.com.
@   3600    CNAME   sub2.example.com.
    3600    MX      10 mail.example.com.

will produce:

> zone = DNS::Zone::load(File.read('test.zone'))
> zone.records.each{ |r| puts r.label }
  @
  sub
  sub.sub

where the third label should be 'sub'.
