Re: [Dnsmasq-discuss] Sort of sync DNS servers in a VPN connected network
No, the first two didn't take because the from: email didn't match my mailing list registration. I then sent the third message with the right from: field. For convenience, I then registered the other email, not realizing that the first two blocked emails would then go through. Won't happen again.

Did you mean to send this three times?

Sounds like this: http://rob0.nodns4.us/dnsmasq.html Sorry, I just noticed that I never managed to link that from the main page, so it probably does not rank well in search engines. Note that you don't need to reinvent the DNS notify concept. In fact you can keep it simple as in my howto, with static entries for the various remote sites. If one of the sites is unreachable via the VPN, no problem if those names fail to resolve. -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject: ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
[Dnsmasq-discuss] Sort of sync DNS servers in a VPN connected network
I have a home network (call it 10.2.0.0/16) and multiple VPN connected networks (10.x.0.0/16). I would like each of the 10.x networks to have a separate dnsmasq, with their own DHCP and DNS server. However I'd like the 10.2 DNS server to hold DNS information for all of the networks. Thus I could first check the local (10.x) and then the home (10.2) DNS, ensuring I get information for all devices, no matter where the host is. I can't see an easy way to do this, but maybe I'm missing something. I have a proposal that seems simple. If the 10.x dnsmasq servers had a mechanism for forwarding DHCP requests/renewals as advisory only to upstream dnsmasq servers, and then the upstream servers would simply remember the bindings in the relevant DNS database, I'm pretty sure my problem would be solved. I would be fine with UDP advisory messages, as if some updates get lost there will be later updates to keep the upstream DNS database in good shape. This is somewhat similar to the "--dhcp-script" option, but I need every request/renewals to be forwarded, and I need dnsmasq to accept such advisory requests. I envision something like "--send-advisory-updates=" to cause dnsmasq to start sending advisory updates, and the dns server would need to be able to handle these update requests. ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
