Use of alternate DNS

[landolfi-us]

Hi,

I promise (probably) that this is the last question from me, but: I am trying to run ytuner and pi-hole on the same box but both want control of Port 53. So on RPi, I have specified an alternate DNS port for UDP in ytuner.ini (5003) but when I start YTuner, I get:

Nov 13 21:44:59 raspberrypi4b ytuner[37773]: 13-11-25 21:44:59 : Err : DNS Server error: Could not bind socket..

Besides setting the port in ytuner.ini, is there anything else I need to do? I have read and re-read ytuner.ini comments and don't see anything additional there. I am not running any firewall, and the command 'sudo lsof -i :5003' and 'sudo netstat -tuln | grep udp' do not show port 5003 in use.

@landolfi-us that is same setup I do prefer.

1. leave pihole enabled as dns !
2. Open ytuner.ini and disable ytuner internal dns resolver
3. use dnsmasq functionality from pihole to redirect vtuner.com

you will found it in pihole v6 under All-Settings-> Miscellaneous-> misc.dnsmasq_lines

add like this: (attention, 127.0.0.1 could work) I didn't use pihole and ytuner on same device.

address=/radioyamaha.vtuner.com/127.0.0.1
address=/radioyamaha2.vtuner.com/
address=/primary1b.vtuner.com/127.0.0.1
address=/backup2.vtuner.com/

so what you want will work with this setup.

read dnsmasq setting requirements properly !

You are amazing, thank you!

I'm running Pi-Hole Web 6.3 and in the web UI under Settings I see "Local DNS Settings" where I can enter domains and IP addresses. So if I am understanding, I should put the URLs my amp will query (denon.vtuner.com, denon2.vtuner.com, vtuner.com) as domains, each to 127.0.0.1.

In any event, does the fact that my DNS port entry in ytuner.ini didn't work mean that I should enter that as an issue? Should that entry alone have caused YTuner to listen on the specified port?

@landolfi-us I may need to explain myself a little more clearly.
Dnsmasq in pihole handles DNS resolution for the denon.vtuner.com domain. If you enter this in the correct place in pihole.toml or in the pihole web GUI in the location I described before.

Once you have done this, you can use nslookup to query the Denon.vtuner.com domain. I currently assume that it will work with the localhost entry 127.0.0.1 as the destination address. Otherwise, take the IP address from your pihole. Like 192.168.1.10 (if the pihole have the address in your network), you just have to adjust it.

If the query of denon.vtuner.com to the pihole address on the yes then also ytuner is accessible on port 80, it should work. However, it is important that you remove the web portal from port 80 for pihole and use a different port or only 443.

If you have any further questions, I will be happy to explain.

Happy radioying

I think you mean entries like these in a conf file:

# Add specific A records for local hosts
address=/denon.vtuner.com/192.168.1.1xx
address=/denon2.vtuner.com/192.168.1.1xx

and I should follow these instructions in dnsmasq.conf:

#           ANY OTHER CHANGES SHOULD BE MADE IN A SEPARATE CONFIG FILE
#                       WITHIN /etc/dnsmasq.d/yourname.conf                                               
#    (make sure misc.etc_dnsmasq_d is set to true in /etc/pihole/pihole.toml)           

?

For this

However, it is important that you remove the web portal from port 80 for pihole and use a different port or only 443.

Instead of changing port 80 in Pi-Hole, could I instead use an alternate port for YTuner using for example WebServerPort=8080? Would that produce the same result?

1. use pihole web on port 443 only or change it to 8080,443 (see pihole v6 documentation !) pihole web port 80 could not be used together with ytuner on same machine !

2. ytuner runs on port 80 (this could not be changed !, this is while demon radio needs the connection on port 80 !

this setup is a must have ! Try not use other options or ports !

3. dnsmasq setup is needed ! I have described it properly.

4. if you setup this properly, no change on your denon radio is needed. It will automatically use ytuner connection on port 80.
   (dhcp setup is default for the radio devices)

5. view the ytuner logs. You will see the radio connections in log.

6. come back when you have setup done.

7. for modifying stations.ini or stations.yaml read Greg's documentation !

If you try using ytuner on other web Port than 80. you're goin failed ! Only the ytuner internal dns port could be disabled while Pihole do the job.

All possible questions are fully answered.

Have a great day !

Success! For anyone wlse who wants to run YTuner on the same box with Pi-Hole, if you are running a current version of Pi-Hole, you can make the Pi-Hole settings changes in the Pi-Hole web UI:

1. Stop YTuner if it is running.
2. Disable YTuner's DNS server (in ytuner.ini, [DNSServer] section, Enable=0)
3. Use Pi-Hole Web UI to change web port to something else, in my case 8080 (Settings/All Settings/webserver.port, change 80o entries to xxxxo where xxxx is your desired port other than 80)
4. Use Pi-Hole Web UI to add a Local DNS record for denon.vtuner.com (Settings/Local DNS Records, use denon.vtuner.com as domain and IP of Pi-Hole and YTuner server box as IP)
5. Optional but recommended: Run nslookup denon.vtuner.com to check correct resolution of IP.
6. Start YTuner.

Many many thanks to Beatrice for patiently explaining the steps to a guy with 2 weeks of Linux experience. She is a treasure.

Point 4 is a little bit incorrect. But it will work too.

It isn't a proper dns masquerade setup.

You've set up a local dns record, which is not the same like masquerading.
