[Dnsmasq-discuss] Getting 'REFUSED' from dnsmasq - possible reasons?

[Chris Green]

I have dnsmasq 2.62 on a RasberryPi on my LAN, it's been doing DHCP
and DNS quite happily for some years now.

I've suddenly started getting REFUSED back, sometimes, e.g.:-

    chris at esprimo$ host news.plus.net
    Host news.plus.net not found: 5(REFUSED)
    chris at esprimo$ 

but another system on the same LAN gets an address:-

    chris$ host news.plus.net
    news.plus.net is an alias for usenet.plus.net.
    usenet.plus.net is an alias for europe.isp.giganews.com.
    europe.isp.giganews.com has address 216.166.105.145
    chris$ 

It's not always the same system that's getting the 'REFUSED' message
so I *think* something odd may be happening to dnsmasq.  Does anyone
have any idea what the problem might be?


Further information, wierdly 'dig' works OK:-

    chris at esprimo$ dig news.plus.net
