QUESTION
I got the mDNS responder working on my ESP8266. It's been working for weeks, I can ping, nslookup and go to the web page. I'm using win10 and Android phone, both worked great. Then it appeared to stop responding to the local name (IP still works fine). The weird part is, when I turned on the debug messages on the console, mDNS still appears to be working, but the clients still can't find it.
Below are debug logs, but from what I can tell it should be working. Any mDNS experts out there that can see what is going wrong? Thanks!

This can be done, either modifying the ansible.cfg, if you want to apply it on your whole Ansible installation, e.g.

QUESTION
My applications have been pretty successful at using mDNS to advertise and discover services. However, I was looking up documentation and found that Apple has flagged their Bonjour classes as deprecated: https://developer.apple.com/documentation/foundation/bonjour I've been searching, but I haven't found any indication of what I should use instead. What framework am I supposed to use to do mDNS if Apple drops NetService and NetServiceBrowser some time in the future?
...ANSWER
Answered 2021-Jul-14 at 22:32I think I've seen some post on the Apple developer forums mentioning this. They seem to be pushing folks towards Network Framework. It appears nw_listener_set_advertise_descriptor is the replacement. See: https://developer.apple.com/documentation/network/2976786-nw_listener_set_advertise_descri

QUESTION
I feel like this question has been asked a bunch of times, but none of the answers I have found seem to be working for me. I'm extremely new to CMake and C/C++ as I come from the world of Java, and am struggling to understand cmake and how it works.
Anyways, basically I have the folder structure below. This is an esp-idf project, so I don't know if that has anything to do with what I'm running into.
...ANSWER
Answered 2021-Jul-09 at 13:46The ESP-IDF build system is built on top of CMake. This means you can use all the standard features of CMake in your files. However, the the ESP-IDF system predefines many functions, and makes many assumptions about the layout of your project, supposedly to make things "easier". Instead of reading CMake documentation, start by reading and understanding the ESP-IDF build system documentation:
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/build-system.html
It looks to me like there is a particular layout expected for subcomponents, including the format of the CMakeLists.txt file. Specifically, move Metriful under a new directory called components, or add Metriful to EXTRA_COMPONENT_DIRS near the top of your root CMakeLists.txt
If Metriful is not written as an esp-idf component, this may not work. However, the document also describes how to link to "pure CMake" components, which will look something like this (at the end of your root CMakeLists.txt).

I am currently doing this tutorial. And on the same machine it worked as expected: The nodes are connecting and are creating and finalizing blocks. But now I want to do the same over the internet. So I have a server (Ubuntu 16.04 xenial) with open port 30333 on which I am running this command:

QUESTION
This question follows on from:
Where can I obtain the mdns.service file needed for building mDNS in Yocto?
Looking at the "mdns 878.200.35" Yocto recipe:
https://layers.openembedded.org/layerindex/recipe/109743/
There are two .patch files linked:
build.patch
0001-nss_mdns-Do-not-include-nss.h-when-libc-glibc.patch .
Opening those links, their pages show minus and plus git-view change markings, with triple-minus and triple-plus markings in pink and green and header and footer text that sure don't look like they belong in code. StackOverflow won't
let me type what I mean literally here.
To use these in the bitbake, should I edit-off that stuff? For example, in build.patch, it looks like I should delete the header lines:
(StackOverflow won't let me post these; first it says they need to be formatted as code and then it says it's bad code.)
and the two last footer lines.
(ditto)
Also delete the lines in pink beginning with "-" and replace the "+" signs at
the beginning of the remaining green lines with a space each (StackOverflow
allowed me to type a literal minus and plus here).
And do the similiar things in
0001-nss_mdns-Do-not-include-nss.h-when-libc-glibc.patch.
Is that right? Can you follow the blocks above? StackOverflow wouldn't let me
format them in code blocks or even include them in this post, which tends to
make me think they shouldn't be in the files to be used in the recipe.
I tried cloning: git://git.openembedded.org/meta-openembedded
and looking at the two files as downloaded to my computer:
root/meta-networking/recipes-protocols/mdns/files/build.patch
root/meta-networking/recipes-protocols/mdns/files/0001-nss_mdns-Do-not-include-nss.h-when-libc-glibc.patch
They still have the same - and + git-view change markings, --- and +++ markings and header and footer text that sure don't look like they belong in code.
Are those files really meant to be used as is like that or do I need to edit them as I described above?
Now I'm thinking that since they are that way in the actual repository, that
Yocto bitbake can read that, skip over the non-code headers and footers and
apply changes noted in git-view format. Do you think? They are ".patch" files, after all. Yocto really is a miracle when it works. That's the first thing that I'm going to try.
Continues!: How do I strip and objcopy a built .so file in the Yocto bitbake compile step?
...ANSWER
Answered 2021-Feb-28 at 08:23Just download the plain files and put them in your layer.
Those files are absolutely valid patches, otherwise they wouldn't be in the upstream layer in the first place.
What's before the first --- is what's going to be the commit title (first line) and commit log of the git commit created when git applies the patch.
The +++ and second --- are to identify the files to which the patch applies. The -- at the end is just to tell git tool to ignore what lies after, which is the version number of git that was used to create said patch (with git format-patch).

Install mdns
You can use mdns like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
