[Dnsmasq-discuss] Syntax for srv-records

My guess is that you need to add the domain to the last two.

eg _sip._tcp gets the domain (as specified to dnsmasq by the domain
keyword) added automatically, so assuming

domain=guido.org
srv-host=_sip._tcp,sipx2.example.org,5060,20,10

You'll get a SRV records called
_sip._tcp.guido.org

once you start adding anything else, dnsmasq assumes you're specifying
the domain, so


 srv-host="_sip._tcp.rr",sipx2.example.org,5070,20,10

gives you a record called _sip._tcp.rr, but you probably want a record
called _sip._tcp.rr.guido.org, so you need to specify that completely

srv-host="_sip._tcp.rr.guido.org",sipx2.example.org,5070,20,10


Cheers,

Simon.
