![]() But that network is decidedly slanted at letting you get to the outside world. All of these options are cheaper than ever before. ![]() If you are out in the sticks, you can consider satellite. Today boards like the Raspberry Pi, the Beagle Bone, and their many imitators make it easy to get a small functioning computer on the network - wired or wireless. But your toaster or washing machine probably didn’t have a cable next to it in those days. The TINI boards I used (later named MxTNI) had an Ethernet port. Back in 2003, it wasn’t always easy to get a board on the Internet. It also means you get a lot of data you have to find a reason to use. That means you can connect things you never would have before. The big news - if you can call it that - is that the network is virtually everywhere. But my point is, the Internet of Things isn’t a child of this decade. Back in 2003, I wrote a book called Embedded Internet Design - save your money, it is way out of date now and the hardware it describes is all obsolete. If you are a long-time Hackaday reader, I’d imagine you are like me and thinking: “so what?” We’ve been building network-connected embedded systems for years. My dnsmasq must have been compiled with a strict option to default with.Everyone’s talking about the Internet of Things (IoT) these days. Then I added the following to my nf to fix it: rebind-domain-ok=/// rebind-domain-ok=/domain1/domain2/domain3/Īrmed with that knowledge, I see that is infact what is happening: # cat /tmp/etc/nf The argument may be either a single domain, or multiple domains surrounded by '/', like the -server syntax, eg. This address range is returned by realtime black hole servers, so blocking it may disable these services.ĭo not detect and block dns-rebind on queries to these domains. This blocks an attack where a browser behind a firewall is used to probe machines on the local network.Įxempt 127.0.0.0/8 from rebinding checks. Reject (and log) addresses from upstream nameservers which are in the private IP ranges. His comment pointed me to the rebind options for dnsmasq: -stop-dns-rebind As soon as he answers, I'll mark his as the answer. It's just public domains that use non-routable commented pointed me in the right direction. Everything works perfectly with local LAN on Windows, OSX and Linux clients resolving public and internal domains and LANs and even hosts without the domain suffix (server-xyz -> resolves to server-xyz.lan). Local resolvs on AdvancedTomato spits out: # cat /etc/nfĪgain. ![]() Version: Dnsmasq version 2.73 # (part of AdvancedTomato)Ĭonfiguration (removed sensitive entries, left example ones): # dhcp-option=lan,3,172.16.1.1 I must be missing some option that I am unable to interrupt reading the MAN page. It's just public records using private non-routable IPs. resolves all IP reverse lookups of private IPs and DHCP leases.resolves all internal private domain and hosts.resolves all IP reverse lookups of public IPs.But yet, all other records using public routable IP addresses work just fine, on the same domain!Įverything else is 100% working normally with local dnsmasq: This is all 100% consistent of all 200+ servers registered with 4 different public domains across several subnets, all using a private non-routable IP address. These IP addresses are part of our Amazon AWS private subnets, and we have VPNs to gain access to them. ![]() Notice the entry properly resolvs to a non-routable IP address of 10.1.XXX.XXX? That's my problem, that does not work with my local dnsmasq on the local network. *** Can't find : No answerīut switching to a public DNS works fine: $ nslookup Our DNSMasq is not able to resolve A, CNAME nor Alias records from public domains that specify private IP addresses.
