It has 8 ports. I setup 2 vlan, one for dmz, one for lan. So there is one cable from my server dmz port to the dmz vlan, same for lan. The switch is configure to use dhcp for its ip. However, it requests dhcp from all ports.

[Dnsmasq-discuss] ignore mac address for one of the dhcp
I am running dnsmasq on a multiple port box. Following are dhcp config for the lan and dmz ports: --- ## LAN dhcp-range=tag:lan,::1,constructor:lan,ra-names,72h # IPv6 dhcp-range=tag:lan,172.16.168.130,172.16.168.250,72h # IPv4 dhcp-option=tag:lan,option:router,172.16.168.1 # option 3 default gw dhcp-option=tag:lan,option:dns-server,172.16.168.1 ## DMZ dhcp-range=tag:dmz,::1,constructor:dmz,ra-names,72h # IPv6 dhcp-range=tag:dmz,10.10.10.100,10.10.10.120,72h # IPv4 dhcp-option=tag:dmz,option:router,10.10.10.1 # option 3 default gw dhcp-option=tag:dmz,option:dns-server,10.10.10.1 --- They work correctly for network connected to those ports. However, I am having issue with the switch which connect to both dmz and lan ports with different VLANs. As those VLAN ports share the same mac address, sometimes the switch will pick up IP from the lan side, and sometimes from the dmz side. How can I make dnsmasq only serve IP on the lan side for this specific mac address?

You will need "log-queries=extra" in config to see it. Then use nslookup/dig to different domains.

Re: [Dnsmasq-discuss] "--all-servers" always on?
There is no "default" option. It actually give error if I add it by itself or "all-servers=default". I went through the man page again and there is no other option affecting this behavior.

Re: [Dnsmasq-discuss] "--all-servers" always on?
Base on my understanding of the manpage, "all-servers" means dnsmasq will send query to all servers at once and use the 1st response. I am seeing all my queries, if not already in cache, are sent to all servers configured. But I don't have "all-servers" set. I want to turn off this behavior.

It should be off, base on manpage. And I don't know how to set a "off" to it.

[Dnsmasq-discuss] How to update ipv6 for own interface? (Updated info)
Ok, let me elaborate more. I have following setup: Linux router server: - OS: Ubuntu 18.04 - wide-dhcp-client on external(internet facing) nic - dnsmasq on lan interface(hostname: router) as dns, ipv4 + ipv6 dhcp - lan interface IPv6 configure by wide-dhcp-client, IPv4 static(172.16.168.1) via netplan - internal domain: int.johnsiu.com(configure in dnsmasq) Servers on LAN - couple mac, linux machines on lan network - all have static dhcp ipv4 from dnsmasq. - all have ipv4 entry in router /etc/hosts dnsmasq is able to do dns resolve for all linux machines for both ipv4 and ipv6. eg: ssh -4 test.int.johnsiu.com ssh -6 test.int.johnsiu.com However, this does not work for the router lan interface. I already did following: In /etc/hosts: 172.16.168.1 router In /etc/dnsmasq.d/lan.conf, I have following lines for router: dhcp-host=e2:1d:6b:2d:33:e7,172.16.168.1,router,infinite While "ssh -4 router.int.johnsiu.com" works, "ssh -6 router.int.johnsiu.com" doesn't. Is there a way to make it happen? ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
[Dnsmasq-discuss] How to update ipv6 for own interface?
I am using dnsmasq dhcp for both ipv4 and ipv6 and it is able to auto generate the dns entries for both, at least for linux servers. Is there a way to make it do the same on selected interface(s) of the server dnsmasq is running? PS: I already have the server IPv4 entry in /etc/hosts ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
[Dnsmasq-discuss] "--all-servers" always on?
OS: Ubuntu 18.04 with all updates dnsmasq version: 2.79-1 According to man page: --all-servers By default, when dnsmasq has more than one upstream server available, it will send queries to just one server. Setting this flag forces dnsmasq to send all queries to all available servers. The reply from the server which answers first will be returned to the original requester. I don't have that flag in command line or in the config file. However with "log-queries=extra" in config file, I am seeing following: Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 query[A] news.com from 10.10.10.101 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 2001:1998:f00:2::1 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 2001:1998:f00:1::1 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 2606:4700:4700::1001 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 2606:4700:4700:: Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 2001:4860:4860::8844 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 2001:4860:4860:: Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 209.18.47.63 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 209.18.47.62 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 209.18.47.61 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 1.0.0.1 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 1.1.1.1 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 8.8.4.4 Dec 09 11:29:24 door dnsmasq[9403]: 3640 10.10.10.101/49351 forwarded news.com to 8.8.8.8 Dec 09 11:29:25 door dnsmasq[9403]: 3640 10.10.10.101/49351 reply news.com is 35.190.79.82 Is --all-servers behavior changed to default on?
