This repository contains the ancient patch (dated of April 7, 2003) that extends Michael Handler's SRV patch to support syntactic sugar NAPTR entries. These two resource records are used by current DDDS RFCs (340x).

This is being maintained here just for historic purposes.

Original message posted at dns@list.cr.yp.to:

a) For SRV records, use the following format in tinydns-data (same as Michael Handler's patch):

Sfqdn:ip:x:port:weight:priority:ttl:timestamp

"Standard rules for ip, x, ttl, and timestamp apply. Port, weight, and priority all range from 0-65535. Weight and priority are optional; they default to zero if not provided."

Sconsole.zoinks.example.com:1.2.3.4:rack102-con1:2001:69:7:300:

b) For NAPTR records, use the following format:

Nfqdn:order:pref:flags:service:regexp:replacement:ttl:timestamp

The same standard rules for ttl and timestamp apply. Order and preference (optional) range from 0-65535, and they default to zero if not provided. Flags, service and replacement are character-strings. The replacement is a fqdn that defaults to '.' if not provided.

Nsomedomain.org:100:90:s:SIP+D2U::_sip._udp.somedomain.org
Ncid.urn.arpa:100:10:::!^urn:cid:.+@([^\.]+\.)(.*)$!\2!i:

c) This patch makes axfr-get decompose SRV and PTR records and write them out in native format, rather than opaque (see M.H. patch comments). This one makes axfr-get convert NAPTR records to the format explained above.

d) It extends the dnsq and dnsqr to support SRV and NAPTR accordingly. Example:

$ dnsqr naptr somedomain.org
35 somedomain.org:
x bytes, 1+1+0+0 records, response, noerror
query: 35 somedomain.org
answer: somedomain.org 78320 NAPTR 100 90 "s" "SIP+D2U" "" _sip._tcp.somedomain.org

$ dnsqr srv console.zoinks.example.com
33 console.zoinks.example.com:
85 bytes, 1+1+0+0 records, response, noerror
query: 33 console.zoinks.example.com
answer: console.zoinks.example.com 300 SRV 7 69 2001 rack102-con1.example.com
