Overview

Easyzone is a package to manage the common record types of a zone file, including SOA records. This module sits on top of the dnspython package and provides a higher level abstraction for common zone file manipulation use cases.

Main features:

• A high-level abstraction on top of dnspython.
• Load a zone file into objects.
• Modify/add/delete zone/record objects.
• Save back to zone file.
• Auto-update serial (if necessary).

Requirements

• dnspython - http://www.dnspython.org/

$ easy_install easyzone

Examples

easyzone:

>>> from easyzone import easyzone
>>> z = easyzone.zone_from_file('example.com', '/var/namedb/example.com')
>>> z.domain
'example.com.'
>>> z.root.soa.serial
2007012902L
>>> z.root.records('NS').items
['ns1.example.com.', 'ns2.example.com.']
>>> z.root.records('MX').items
[(10, 'mail.example.com.'), (20, 'mail2.example.com.')]
>>> z.names['foo.example.com.'].records('A').items
['10.0.0.1']

>>> ns = z.root.records('NS')
>>> ns.add('ns3.example.com.')
>>> ns.items
['ns1.example.com.', 'ns2.example.com.', 'ns3.example.com.']
>>> ns.delete('ns2.example.com')
>>> ns.items
['ns1.example.com.', 'ns3.example.com.']

>>> z.save(autoserial=True)

ZoneCheck:

>>> from easyzone.zone_check import ZoneCheck
>>> c = ZoneCheck()
>>> c.isValid('example.com', '/var/named/zones/example.com')
True
>>> c.isValid('foo.com', '/var/named/zones/example.com')
False
>>> c.error
'Bad syntax'
>>>
>>> c = ZoneCheck(checkzone='/usr/sbin/named-checkzone')
>>> c.isValid('example.com', '/var/named/zones/example.com')
True
>>>

ZoneReload:

>>> from easyzone.zone_reload import ZoneReload
>>> r = ZoneReload()
>>> r.reload('example.com')
zone reload up-to-date
>>> r.reload('foo.com')
rndc: 'reload' failed: not found
Traceback (most recent call last):

>>>
>>> r = ZoneReload(rndc='/usr/sbin/rndc')
>>> r.reload('example.com')
