Pure Radios using Frontier Silicon Chip lookup pure.internetradiofrontier.com

[gavinwill]

Hi

I have an old Pure Evoke F3 which uses the silicon frontier chip. Initially when setting up Radio-DNS and Radio-API it would not work. On looking into this further the Pure radios first lookup another domain

TCPDUMP of DNS Requests on Radio-DNS.
In this tcpdump 192.168.160.8 is my Pure Radio and pf is my router (and upstream DNS server)

11:39:12.777426 IP 192.168.160.8.50176 > radio-dns.53: 2+ A? pure.internetradiofrontier.com. (48)
11:39:12.778702 IP radio-dns.59011 > pf.53: 2+ A? pure.internetradiofrontier.com. (48)
11:39:13.767302 IP 192.168.160.8.50176 > radio-dns.53: 2+ A? pure.internetradiofrontier.com. (48)
11:39:13.768619 IP radio-dns.59391 > pf.53: 2+ A? pure.internetradiofrontier.com. (48)
11:39:13.774373 IP pf.53 > radio-dns.59011: 2 2/0/0 CNAME shim-pri.wifiradiofrontier.com., A 192.248.188.143 (105)
11:39:13.775158 IP radio-dns.53 > 192.168.160.8.50176: 2 2/0/0 CNAME shim-pri.wifiradiofrontier.com., A 192.248.188.143 (105)
11:39:16.214951 IP pf.53 > radio-dns.59391: 2 2/0/0 CNAME shim-pri.wifiradiofrontier.com., A 192.248.188.143 (105)
11:39:16.215921 IP radio-dns.53 > 192.168.160.8.50176: 2 2/0/0 CNAME shim-pri.wifiradiofrontier.com., A 192.248.188.143 (105)

I can redirect DNS queries on my router and redirected pure.internetradiofrontier.com to point to my radio-api container 192.168.200.31

dig pure.internetradiofrontier.com @pf +short 
192.168.200.31

At this point restarted Pure radio and radio-api just worked.

Not sure of the usage from Pure radio users but feel that adding another domain into

Radio-DNS-Server/dns/hama.py

Line 11 in a1e8cc6

_DOMAIN = "wifiradiofrontier.com."

would support this quite easily and mean i dont need to run an additional redirect on my router whilst also catching the whole domain

Happy to add a PR if needed.

Adjusting hama.py to this works for me

	_DOMAIN = "wifiradiofrontier.com."
	_PUREDOMAIN = "internetradiofrontier.com"
	_TIME_DOMAIN = "time.wifiradiofrontier.com."
	_UPDATE_DOMAIN = "update.wifiradiofrontier.com."

	def __init__(self):
		self.do_lookup = Config["DO_LOOKUP"]

	def match_domain(self, question:DNSQuestion) -> bool:
		if isinstance(question, DNSQuestion):
			if question.qname.matchSuffix(self._DOMAIN) or question.qname.matchSuffix(self._PUREDOMAIN):
				if question.qtype == QTYPE.A:
					return True

		return False

Many Thanks
