SOLVED: dns: Failed to bind to port 53

[juergenoldbg]

I am trying to get my ipdio mini back to work with your description, that I found here.

I setup the ipdio, as you describe it in Step 1 with a static IP. I restart the ipdio and check, if the device is listed in my network by doing a nmap on my Linux-machine and it is listed.
Then I start the programm, that I downloaded from
https://leo.pfweb.eu/dl/tLoDi for Linux
as root and submit DNS, own IP of the Linux-machine and the location of the patch file.
When I klick start, I get the (error-)message
dns: failed to bind to port 53: Address already in use

When I start the firmwareupdate on the ipdio, I get the message to check my network-settings. I have double-checked, that the 1st dns on the ipdio is pointing to my PC. I guess, this message is due to the 'failed to bind'-message on the PC. I am using Lubuntu 22.04. Any idea, what I could do?

Thanks, Jürgen

Hi, have you tried googling? Probably you have some other service already listening on port 53 on your PC. That's all I can help, perhaps you should check the results from:

This was a perfect hint. After I did this changes, the error-message 'Failed to bind ....' didn't show up anymore.
I could now start the server.
Afterwards I started the firmwareupdate on the ipdio and answered with yes. I could see on the screen of my pc, that the configuration of the ipdio was correct as right away some messages appeared in the server-monitor. The last message said something like 'patch-file transferred' and my ipdio said something like 'testing patchfile'
As you suggested I did this five or six times as the ipdio just rebootet after this testing-message. The messages listed on your webpage never appeared.

Do you have any suggestions, how I should continue.

Thanks

If it says "testing patchfile", you probably have just used the sharpfin-test.patch file. It does not update, just tests the system.

Use the sharpfin-ep2.install file in this repository.

Let me just make sure I do understand it correctly. Before I can use sharpfin-ep2.install, I have to install Sharpfin-base_0.3.patch using the 'server'-software.
I did so and I got the sharpfin-website under the IP I choose for the Ipdio. Everything looked fine up until then.
As described on 'https://www.megapico.co.uk/sharpfin/mediaserver.html' I opened the admin-page, selected 'Install addon' and choose
http://www.gforums.de/daten/sharpfin-ep2.install
Something happened on the display of the ipdio, but don't ask what. The radio rebooted and from then on I was not able to http to the IP of my radio anymore. I did a factory reset and started from the beginning with no success. I can ping the radio, but cannot connect.

Thanks for helping

I found the solution and now my IPdio Mini works fine (for now, one station). The solution is described here:
