I'm looking for something similar to teamviewer or zoom.us remote control, where one user can share his desktop and the other user can control it.
Dayon is for people who needs help with their pc.
Therefore it would be great if the dayon Application would update itself on Ubuntu, when you add a ppa address to the package sources.
When using a different keyboard layout, the connection gets interrupted and the assistee gets an error message when pressing certain keys.
Steps to reproduce:
There are a couple of prebuilt libraries in lib/
, and I think their licenses require at least attribution. A link in the readme to their homepages[1] would also help distro packagers like me to build Dayon! completely from source, which is desirable or often even required for inclusion in distros.

Is your feature request related to a problem? Please describe.
I'm always frustrated when family members I try to support managed to change IP and port in "Connections Settings" although I told them just to click "ok" after starting "Dayon assisted".
Describe the solution you'd like
Starting "Dayon assisted" instead of showing the "Connections Settings" let users add Assistant IP Address
and Assistant Port Number
as a named profile, like "IT team" or "My son/daughter".
It would be great to have these profiles in config files which could be used to roll out Dayon with a certain setup on multiple machines.
Describe alternatives you've considered
None yet.
Additional context
A lot of users don't know what an IP address is or what a port number is about. A preset profile would make it much more easy for users with no IT knowledge to ask for help (once Dayon was set up by someone with IT knowledge).

I'm always frustrated when I need to help family members with updates but we don't find time window where both ends are online the same time. So they have to wait for me or I for them just to let them click "ok".
Describe the solution you'd like
Starting "Dayon assisted" the Connection Settings should provide the following opt-in check boxed:
[ ] Retry connection establishment until assitant is available.
[ ] Retry connection establishment after connection loss.
Option 1 would try to connect to the "Dayon assistant" until the remote client is started/online.
Option 2 would retry to establish the connection if one side had a connection problem.

None.

Describe the bug

Describe the solution you'd like
A yml config autoread when found next to the binary to set custom token/ip servers without rebuild, or to turn off external servers altogether. IP/Port is all that's needed after all.
I was reading the site, and the README.md, but didn't see anything about the rendezvous server listed. Just the application. If the application connects to an outside server to "meet up" with an assistant, then it would be nice to be able to run my own rendezvous server as well.
Is this possible today? If not, will it be in the future?

When you want to install or remove something on the client computer you need to give admin rights
"Do you want to allow this app to make changes to your device? " YES or NO
Then you must click to yes, but you don't see anything at this moment black or grey screen. The asking for the rights is freeze the connection. When the client has clicked yes the connection and view is back.

Hi,

when we try to connect two laptop which are on different network or want to connect over internet then from the key we generated from the Assistant app if i write that exact key in assisted app then first 2 sec they fetch that Assistant computer public ip and port but in last after 2 sec it comes with connection timeout (some_ip:port).
and 2nd bug is in local it is working means in same network and in which we see that screen are black and white not colour screen as we normally see it.
Hi I'd love it if we could separate the Assistant and the Assisted.
Ideally the assisted would have a single, executable (no install required) that they simply run and let us know the number we need to enter to connect.
This will help understand:
This way they don't have to:

Dayon! requires a bit of knowledge about port forwarding on the assistant side, and that's perfectly fine, but I think the process could be made easier by adding UPnP support directly in Dayon.
Describe the solution you'd like
When the assistant server is started, Dayon! automatically opens the port (or a random port) with UPnP. When it's stopped, the port is closed.
Describe alternatives you've considered
Just let the assistant user handle it. There are standalone UPnP clients after all.

Hi,
currently the idea of Dayon is that an assistant has the possibility to open a port on the assistant's side which allows the user who needs help to connect to the assistant's system. Unfortunately my current ISP uses some kind of Carrier-Grade NAT so that I don't even have an own public dynamic IP anymore and can technically not offer that someone connects to my system.
Is there a possibility to add an option "Connect to assisted" (so the other way around of the initial idea)?
This would only work for systems the assistant has prepared, of course. In my case: The client of parents behind an ISP which still offers a public IP. So I could give my parent's systems a fixed IP and set up a port forwarding to the systems.

It's good that Dayon! is e2e-encrypted, but as far as I can see it's still susceptible to MITM attacks.
Describe the solution you'd like
When the assisted connects to the assistant, a fingerprint is shown on both sides, and the two parties have to confirm a match via phone/message/other channel. This could happen on every connection or the certificate could be trusted on first use. Short Authentication Strings could be used for easier verification.

Dear developer,
I only have a question, maybe you can explain it. I am wondering, when I create just a token, how does the assisted computer know, where it has to connect to? If I tell him my ip address, that is clear, but somehow the assisted has to know, what is my ip address.
As far as I understood, there is a server in the middle, but should mean, that
a) this server must be existent, and who owns this server?
b) the connection is handled by this server
c) the ip or name of this server is hardcoded somewhere
d) no more server = no more token connection?
Or is it some other way using to get the connection? At the moment I am still using the non-token connection by telling the assisted my ip address, this looks more secure for me as it is really end-to-end.
Thanks for any feedback!
Best regards
Hans-J. Ullrich
P.S. Dayon! is running great, using it with some friends, who do have very litttle knowledge with computers, and I am happy, they can at least handle Dayon!

Hi, and thank you for this project! It's nice to have a private alternative to the giant corps. Punching through NAT by just hosting it yourself is nice (well, unless you're on cgnat). And it means one less thing to deal with for the other side.

Hi, I'm trying to package Dayon! for NixOS, and I need to specify the license. I see that the license file contains the GPL version 3, but nowhere in the project is mentioned whether it is licensed under GPLv3 only or GPLv3 or any later version. I think the deafult is "only", but if you confirm I can set "or any later version" on the package.
Great project by the way! Something that requires the assistant --not the assisted-- to open ports is exactly what I was looking for!
I downloaded Quick Launch Versions to my computer.
However, smartscreen thinks these files are dangerous.
Windows does not allow these files to be downloaded.
