Diversion Odd DNS issues

  • SNBForums Code of Conduct

    SNBForums is a community for everyone, no matter what their level of experience.

    Please be tolerant and patient of others, especially newcomers. We are all here to share and learn!

    The rules are simple: Be patient, be nice, be helpful or be gone!

Code:
admin@DSL-AX82U-4B38:/tmp/home/root# cat /tmp/resolv.dnsmasq
server=127.0.1.1
admin@DSL-AX82U-4B38:/tmp/home/root#
 
Okay, so DNS Director is disabled, and DoT is also disabled.

Code:
admin@DSL-AX82U-4B38:/tmp/home/root# cat /tmp/resolv.dnsmasq
server=1.1.1.1
server=1.0.0.1
admin@DSL-AX82U-4B38:/tmp/home/root#
admin@DSL-AX82U-4B38:/tmp/home/root# nslookup assets.penny-arcade.com
Server:    127.0.0.1
Address 1: 127.0.0.1 localhost.localdomain

Name:      assets.penny-arcade.com
Address 1: 0.0.0.0
Address 2: ::
 
Forcing nslookup on the router to use google or cloudflare works:

Code:
admin@DSL-AX82U-4B38:/tmp/home/root# nslookup assets.penny-arcade.com 8.8.8.8
Server:    8.8.8.8
Address 1: 8.8.8.8 dns.google

Name:      assets.penny-arcade.com
Address 1: 104.21.64.223
Address 2: 172.67.156.39
Address 3: 2606:4700:3036::ac43:9c27
Address 4: 2606:4700:3030::6815:40df

admin@DSL-AX82U-4B38:/tmp/home/root# nslookup assets.penny-arcade.com 1.1.1.1
Server:    1.1.1.1
Address 1: 1.1.1.1 one.one.one.one

Name:      assets.penny-arcade.com
Address 1: 104.21.64.223
Address 2: 172.67.156.39
Address 3: 2606:4700:3036::ac43:9c27
Address 4: 2606:4700:3030::6815:40df

admin@DSL-AX82U-4B38:/tmp/home/root# nslookup assets.penny-arcade.com
Server:    127.0.0.1
Address 1: 127.0.0.1 localhost.localdomain

Name:      assets.penny-arcade.com
Address 1: 0.0.0.0

Thanks. So can we look at this output:

cat /etc/resolv.conf
Code:
netstat -nlp | grep :53

cat /etc/dnsmasq.conf

Ah. It looks like you've installed a ctrld addon that's replaced the built-in DNS server.
 
Have I. Odd. I do recall considering Unbound as I had it as part of my Pihole setup; but I don't remember anything else. Let me get rid of it...
 
I've already uninstalled it; I remember now that I considered going down the DoT route only and came across ctrld as an option. However, I uninstalled it; but it still seems to be taking over DNS requests. I think I need to look at the dnsmasq config; ctrld's manual says it interfaces with dnsmasq. I did install it after installed Diversion.

Yeah, lots of references to ctrld in there. Can I just nuke the whole file?
You would have to re-install Diversion afterward. Maybe nuke the router to start fresh.

Feels like they borrowed a lot from NextDNS client.

You might be right. I've killed the file, re-installed Diversion and the ctrld reference is still there in netstat. What a ballache

They put the “Control” in “Control-D”…
 
Right, got it. Using

Code:
ps | grep ctrld

I found the /jffs/controld folder, which I rm'd recursively, and rebooted.

Now, netstat gives me

Code:
admin@DSL-AX82U-4B38:/tmp/home/root# netstat -nlp | grep :53
tcp        0      0 127.0.0.1:53            0.0.0.0:*               LISTEN      5167/dnsmasq
tcp        0      0 192.168.0.1:53          0.0.0.0:*               LISTEN      5167/dnsmasq
udp        0      0 127.0.0.1:53            0.0.0.0:*                           5167/dnsmasq
udp        0      0 192.168.0.1:53          0.0.0.0:*                           5167/dnsmasq
udp        0      0 192.168.0.1:5351        0.0.0.0:*                           3845/miniupnpd
udp        0      0 0.0.0.0:5353            0.0.0.0:*                           2889/avahi-daemon:

So we're on to a winner.

I've re-enabled DoT and DNS Director; and assets.penny-arcade.com is now resolving through the upstream Cloudflare DNS server; and the comic panels are loading on my device.

Nice sleuthing; it's been an absolute pleasure. Thank you very much!
