DNS masq related question

[Marcus Yansen]

Did your ctrld listener port change recently from port 5354 to 53? The dnsmasq.postconf suggests it was 5354, but the netstat and /etc/dnsmasq.conf show ctrld listening on port 53 and 5353 now, which could also explain the original dnsmasq startup failure.

To be honest, I have no idea - I was running some commands earlier to verify ctrld was working properly and i may have inputted 5354 but more a as verifying measure based on instructions rather than making any any changes. So the ports in these configs should more/less match? maybe i will download the configurations tomorrow again to compare them together. Or if there’s anything else I should do, please let me know. Thank you for all your help.!

It seems like ctrld should be active on a non-standard port like 5354, and dnsmasq will listen on port 53 and forward queries to ctrld on 127.0.0.1:5354.

Yes, thank you, now I see what you are saying, upon regenerating these, now my dnsmasq.conf also shows "server=127.0.0.1#5354" - just like my dnsmasq.postconf which also shows: pc_append "server=127.0.0.1#5354" "$config_file"
Whereas before the dnsmasq showed ""server=127.0.0.1#53"

cat /jffs/scripts/dnsmasq.postconf

config_file="$1"

# Change /etc/resolv.conf, which may be changed by WAN DNS setup
pc_delete "nameserver" /etc/resolv.conf
pc_append "nameserver 127.0.0.1" /etc/resolv.conf
