dnsmasq

Posting it here as I would like to understand if and how ASUS routers are affected, and if affected is there mitigation. Please move post as applicable. from https://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2025q3/018288.html

Hi everyone, since 3 or 4 weeks I observe connectivity losses of my ASUS AX58u running ASUSWRT Merlin. I figured out, that the problem comes from DNS queries not answered. The log says Apr 10 02:06:25 rc_service: watchdog 1734:notify_rc start_dnsmasq Apr 10 02:06:25 custom_script: Running...

Hi all, I'm really hoping someone can help. I have an Asus AC68u router (which I realise is old and now no longer supported), but it is still going strong. Currently I'm running Merlin firmware 386.13 on it. I have just moved house and moved ISPs. Previously I was with Virgin Media, who...

Hello everyone, As many of you know, the Asus RT-BE88U router does not yet have Merlin firmware support. I wanted to ensure the security and privacy of my network while using the stock Asus firmware, particularly for blocking ads and malicious sites. This led me to adopt and update a project...

I had used kids mode/restricted clients mode for some time and it worked, then after upgrading to some Diversion version (5.1 probably?) all my dhcp clients just stopped working, I had to uninstall diversion to fix things, then I pinpointed the problem to the kids mode. As you can see in the...

Trying to get reverse DNS working for local IP's. So far everything I have tried does not work. I have a number of hosts listed in dnsmasq.conf.add address=/dock.lan/dock/192.168.50.11 dig and nslookup will resolve 'dock' to '192.168.50.11' but will not resolve '192.168.50.11' to dock. Is...

Hi, My internet line has been stuttered and intermittent for some weeks. Last night, I took some time to check. 1. First, my setup: 192.168.7.1: an AC68U with Merlin firmware 192.168.7.110: a Pi running Adguard Home + Unbound only acts as DNS server Both WAN and LAN DNS servers settings on the...

Hello, Last week, I had a trouble with dnsmasq that was restarting so often that I was unable to even have Internet access because I wasn't able to have DNS resolution. I disabled AdGuardHome because I thought it was related (a lot of AdGuardHome's event was registered when dnsmasq was...

I'd like to achieve the following configuration, can anyone tell me what needs to be done? Unbound set up as a recursive name server on my Asus GT-AX6000 Adguard Home (running on a separate local server) Local domain DNS resolving for clients connected to the ASUS (eg. if I connect a device via...

Found dnsmasq can still resolve names but couldn't offer IP address by its DHCP service. Run "service restart_dnsmasq" but no "Done" output. checked syslog, the output was: Apr 18 11:09:31 rc_service: service 23364:notify_rc restart_dnsmasq Apr 18 11:09:31 rc_service: waitting...

I run dnsmasq on my DSL-AC68U (running the Gnuton variant) with a large blacklist file that is on a USB memory stick. A recent (fairly short, half a minute or so) power failure seems to have provoked an odd problem with dnsmasq failing to see when the USB mounts after power up, but when I did...

Hi everyone, I've uploaded Asuswrt-Merlin 3004.388.6_1 test builds that include dnsmasq 2.90 (which contains two security fixes related to DNSSEC). https://www.asuswrt-merlin.net/test-builds Please give these builds a try, both with and without DNSSEC enabled. Let me know if there are any...

Happy holidays everyone, pretty stuck on this one and would appreciate a second set of eyes to see if I missed anything obvious. I'm new to this, so apologies in advance if my understanding is way off. Device: AC68U Firmware: 386.12_4 Summary I'm trying to set up remote access to my network...

After looking through the forum, I think I need to use dnsmasq.postconf to accomplish my goal, but I don't know how. PROBLEM: I use NordVPN's SmartDNS service to stream while traveling; however, they can't resolve one domain I need to use. I have a list of the URLs and IP addresses using the...

Hi all. I am using YazDHCP and it constantly floods in logs: At the same time I don't see anything incorrect in .staticlist: So what is wrong?

Hi All, For some time now once or twice a week my RT-AX86U with up-to-date stock firmware (3.0.0.4.388_22525) will stop resolving DNS. All active connections will continue to work but if I want to connect to a new location DNS won't resolve to an address. I have traced the issue to Dnsmasq and...

Hi, After many attempts, I concluded that probably the nature of repeater mode doesn't allow to set custom DNS on Asus Merlin, perhaps I'm wrong and you guys can give me some hand/workaround. This is my last try. Goal: Set DNS for NEXTDNS / Also their install script does not work on repeater...

I'm writing a custom script about running a second instance of dnsmasq, and I want the second instance to use the default DNS server provided by the OVPN client, but because OVPN provider assigns a new DNS IP address every time it starts up, So I'm wondering where I can check that IP address...

I have noticed some peculiar behaviour which (due to lack of knowledge probably) I wasn't able to explain. While trying to find a problem with dnsmasq's DNS query replies for local domain names (separate story), I was using Diversion to follow the dnsmasq.log with filtering to client's IP...

Hi, encountering really odd DNS issue after dirty-installing 386.9 fw (upgrade from 386.7-2). On the previous versions of firmware, I was using /jffs/configs/dnsmasq.conf.add for local network name resolution in the form of address=/[server.domain]/[ip]. The domain itself is .home, so...
