Never heard of KDEconnect but I once tried a KDE application on a MATE
system and it broke my computer.
If there is anything else then KDE I would quickly switch to that.

If I were wanting a KDE Connect on a LM 22.3 such as Cinnamon, I would
choose a similar function based on my DE's toolkit GTK, such as GS
Connect. That way I don't have to drag in all of that Qt stuff.

https://extensions.gnome.org/extension/1319/gsconnect/

There is a lot of clutter and 'confusion' created by throwing in a
different system like KDE apps based on Qt when LM isn't.

And, if I were 'curious' about KDE Connect, I would boot a live KDE
distro (not LM) to see how it works.

Cinnamon and the other LM DEs have departed SO FAR from Gnome, that such

When you install packages, you're supposed to note what the interface
says about quantity-o-bytes and "list of packages to install". If the
list is ridiculously long, that's your first hint you've invited
Martian Invaders into the house. I've NACKed out of a package
install many times, on seeing just how large the package set
that I'm about to install is going to be.

Well, on the one hand, I was right about KDE Connect requiring a LOT of

But, OTOH, installing KDE Connect on LM 22.3 Cinnamon does result in a 'family' of KDE Connect apps in its menu which seem worthwhile, KDE

Wireshark has Ethernet-Capture and USB-Capture, it may have Wifi-Capture
or that could be an add-on, but it may lack a way of working with
Bluetooth to Bluetooth connections. While your phone could be tethered
with a cable and using rndis or something, it's more likely you are

The daemon mentioned is in the URL-text.

troubleshooting - kdeconnectd # A daemon is name-of-software with a "d" on the end :-)

and is kdeconnectd. That is a process with some degree of elevation,
that runs as a service all the time, and it is going to route something
from one machine to another machine. Since a series of ports were set
aside, it likely keeps track of port usage and the "sessions"
associated with that. For example, your LM223 Cinnamon could have two
phones KDEConnected at the same time, and then a different port
would be used for each one. A similar kind of thing happens
when you have two X11 sessions, one might be on port 6000, the other
on port 6001 and up to 64 ports are set aside for that usage.

The systemd has status checks for daemons. But while we have some
explanations of bits and pieces of the setup here...

https://discuss.kde.org/t/troubleshooting-kdeconnectd-on-linux/27743

there is some more indication of the foreign-ness of it here.

https://askubuntu.com/questions/829628/how-to-disable-kdeconnectd-autostart

Any systemd rules won't help, as this daemon starts via dbus.

A process status command, should show this running as the kdeconnectd daemon.

/usr/lib/x86_64-linux-gnu/libexec/kdeconnectd

and it will have a PID (process ID) or whatever. I'm sure someone
can craft something better than this. This is just muscle-memory for
me from Unix days.

ps aguwwwx | grep -i kdeconnect # sweep for app and daemon

I don't know the answer to your problem -- firewall sounds logical.
with Wireshark running, you could reverse the situation, and
see if the phone "trying to connect the PC" works. Then look at
the Wireshark trace on the LM223 Cinn PC and see if the packets
are arriving or not.

If kdeconnectd was not running, the application portion should
whine that it cannot connect to the daemon. I expect, since you
did not note anything like that, that indeed kdeconnectd is
running. It's still possible for it to be "struck dumb", if it
cannot get the resources it needs. Then you'd have to track
down the log that kdeconnectd dumps, and see if *it* is
whining...

Any systemd rules won't help, as this daemon starts via dbus.

A process status command, should show this running as the kdeconnectd daemon.

/usr/lib/x86_64-linux-gnu/libexec/kdeconnectd

and it will have a PID (process ID) or whatever. I'm sure someone
can craft something better than this. This is just muscle-memory for
me from Unix days.

ps aguwwwx | grep -i kdeconnect # sweep for app and daemon

I don't know the answer to your problem -- firewall sounds logical.
with Wireshark running, you could reverse the situation, and
see if the phone "trying to connect the PC" works. Then look at
the Wireshark trace on the LM223 Cinn PC and see if the packets
are arriving or not.

If kdeconnectd was not running, the application portion should
whine that it cannot connect to the daemon. I expect, since you
did not note anything like that, that indeed kdeconnectd is
running. It's still possible for it to be "struck dumb", if it
cannot get the resources it needs. Then you'd have to track
down the log that kdeconnectd dumps, and see if *it* is

Well, on the one hand, I was right about KDE Connect requiring a LOT of stuff related to KDE that is NOT on a default LM.

But, OTOH, installing KDE Connect on LM 22.3 Cinnamon does result in a 'family' of KDE Connect apps in its menu which seem worthwhile, KDE Connect (make all your devices one), KDE Connect indicator (display info about your devices), KDE Connect settings (which window says, 'If you own an Android device, make sure to install the KDE Connect Android app (also available from F-Droid) and it should appear in the list (also directions to help from kdec wiki) and KDE Connect SMS texting.

The thing is, Axel is trying to get everything running on a
single unified solution.

So far, I'm now advising KDE Connect on LM 22.3 such as Cinn AND KDE Connect from Google Play on his Android Moto device.

I have installed it on another LM machine, and it's great

https://unix.stackexchange.com/questions/524502/kde-connect-not-working-ubuntu-16-04-kde-connect-is-not-discovering-phone-an

~/.config/kdeconnect <=== configuration file

The article there is old, but it is claiming the software may have
an attachment to the use of IPV6. Yet, your other stuff works, so if there
was an issue, all should have been affected the same. On purpose, my
router uses IPV4 only :-)

The commands and approach in the article are also old, like smacking
stuff around with killall and such :-)

Since some of your stuff works and only a few things don't, that
makes it more likely some difference in firewall might be the problem.

You can see the person there, using ps with some options, then grepping
on kdeconnectd. And finding the daemon running from the expected place.

$ ps -eat | grep kdeconnectd

00:00:00 /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd

*******

Some network functions are similar to the following , in that they attach some significance to a program or function, rather than insisting
the user type these rules in manually. At one time, we might name
eight different ports, and expect the user to program things
like a firewall by hand. But now, just like a .desktop file for
program launch, the firewall can be configured as programs need
port ranges.

[kdeconnect]

title=KDE Connect
description=Device Synchronization
ports=1714:1764/udp|1714:1764/tcp

TCP is a reliable three packet kind of protocol, whereas
UDP is a single packet/roll-your-own-reliability kind of
choice. UDP might work on a home wired LAN, where the odds of
a packet getting lost are minimal. Whereas a packet going from
my house to Finland, needs reliable transport and there
are some odds the packet might not arrive at the destination.
KDEConnect is really intended for local use, but transport
over Wifi might not be perfectly reliable, so I could see
TCP being used for that case. It would retry, if the ACK did not
come back.

One of the reasons we try to solve problems, is to become
more familiar with the subsystems in the computer. It's supposed
to make solving the next problem, easier :-) An investment
in the future.

Is the daemon running ?

I don't know what you're asking

-a The state of the application on each
end, hints at how much of each ecosystem is populated and running.
Also, when you hint that the Application is running and can see
other devices, that knocks out a number of possibilities on
at least one end.

yes, the problem is with the LM PC I believe. the phone running KDEc sees other phones and the w11 PC running the app.

Do both Device1

device 1 sees nothing. device 2 sees other devices, as above

and Device2, see Device3, and yet do not see each other

phones see each other and the w11 PC

(as evidence of a "network partition") ?

You've probably done some of this already.

-a-a-a-a https://discuss.kde.org/t/troubleshooting-kdeconnectd-on-linux/27743

no, I hadn't seen that, thanks. I will check it out

I would say "use Wireshark",

I will look into that

-a but the modality might not have a promiscuous
receiver to use.

??? is that something to do with hookers? :)

Wireshark has Ethernet-Capture and USB-Capture, it may have Wifi-Capture
or that could be an add-on, but it may lack a way of working with
Bluetooth to Bluetooth connections. While your phone could be tethered
with a cable and using rndis or something, it's more likely you are
using the Wifi on your phone.

Promiscuous receiver, means the driver (on a shared media) can
"listen" to all conversations, instead of a restricted set of conversations >> when debugging.

So we have your picture now. Something like this.

The daemon mentioned is in the URL-text.

troubleshooting - kdeconnectd # A daemon is name-of-software with a "d" on the end :-)

and is kdeconnectd. That is a process with some degree of elevation,
that runs as a service all the time, and it is going to route something
from one machine to another machine. Since a series of ports were set
aside, it likely keeps track of port usage and the "sessions"
associated with that. For example, your LM223 Cinnamon could have two
phones KDEConnected at the same time, and then a different port
would be used for each one. A similar kind of thing happens
when you have two X11 sessions, one might be on port 6000, the other
on port 6001 and up to 64 ports are set aside for that usage.

The systemd has status checks for daemons. But while we have some
explanations of bits and pieces of the setup here...

there is some more indication of the foreign-ness of it here.

You know, all browsers and android can be loaded with Pushbullet. You do a bit of setup
on both ends, the browser and the android app. You need to make a login. Once
connected you can send/receive text messages and see any notifications.
As for file transfer, I use a 'file manager+' in productivity. https://play.google.com/store/apps/details?id=com.alphainventor.filemanager&hl=en-US&pli=1

One of it's options is 'access to network'. When started, it becomes an FTP file server.
Load a client like filezilla and put in the appropriate host name etc that the app gives
you when started and you can upload and download via your PC. Whole directories, or files.

I find it quite simple.

Fwiw I set up KDE Connect on the Fedora box and got the app for the
Samsung A16. Other than having to turn on wifi for the phone it seems to
work. I'd rather it use Bluetooth but I'm not sure that's an option.
Connect crashes when I try.
