DNSServer
|
||
|
|
=========
|
||
|
|
Also known as a DNS Resolver, the ``DNSServer`` provides a DNS Server simulation by extending the base Service class.
|
||
|
|
|
||
|
|
Key capabilities
|
||
|
|
^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
- Simulates DNS requests and DNSPacket transfer across a network
|
||
|
|
- Registers domain names and the IP Address linked to the domain name
|
||
|
|
- Returns the IP address for a given domain name within a DNS Packet that a DNS Client can read
|
||
|
|
- Leverages the Service base class for install/uninstall, status tracking, etc.
|
||
|
|
|
||
|
|
Usage
|
||
|
|
^^^^^
|
||
|
|
- Install on a Node via the ``SoftwareManager`` to start the database service.
|
||
|
|
- Service runs on TCP port 53 by default. (TODO: TCP for now, should be UDP in future)
|
||
|
|
|
||
|
|
Implementation
|
||
|
|
^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
- DNS request and responses use a ``DNSPacket`` object
|
||
|
|
- Extends Service class for integration with ``SoftwareManager``.
