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.

Describe the bug
I pay to have a fixed public IP from my ISP. When clicking in the Assistant's upper right corner to identify public IP automatically, it shows another value than my public IP. The value seems related to my ISPs DNS range (but this is beyond my competence).

To Reproduce
Steps to reproduce the behavior:

1. Ensure you have a fixed IP as an activated service from your ISP
2. Go to 'Set up connecting IP address'
3. Click on 'Receive me ( public )'
4. The value received is 100.6x.xxx.xx [port] (the ISPs DNS server is 100.6x.x.xx, while my actual public IP is 185.1xx.xx.xx)

Expected behavior
That step 3. Click on 'Receive me ( public )' produces the actual public IP

Screenshots

Desktop (please complete the following information):

• OS: Windows 11

• App variant ms store
• Java version latest bundled

Additional context
When I start the Assisted on another computer and select the correct public IP (and port) to connect with the Assistant it all works well, so it seems it is only if I try to retrieve the public IP or try to connect via access token they fail to connect.

Describe the bug
The last icon to the right (Exit) has been copied to look the same as the Help icon. The fnctionality of pressing the icon is correct, it is only the symbol that is wrong.

To Reproduce
Steps to reproduce the behavior:

1. Start Assistant or Assisted
2. Look at top-right corner
3. See error

Expected behavior
Same icon as in earlier release.

Sorry for all the trouble

Hello, thank you very much for a good program under a free open source license! Added a program to a Russian-language site about free software, here is the link.

I am ready to help with translation into Russian, send the text that you need to translate.

The project is interesting, so please don't abandon it!

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.

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.

Screen capture does not work on systems using Wayland display server in combination with OpenJDK.
(Which is the default on Debian Buster)

To Reproduce

1. Start Dayon Assisted within a session running with Wayland.
2. Connect to the Assistand running on whatever system.
3. Only a plain black screen is transmitted to the Assistant.

Workaround

• Use Oracle JDK/JRE instead
• Or start a X.Org server instead:
  Logout > see the login screen > click the gear icon > select Xorg > login again.

Affected:

• OS: Any linux using Wayland and OpenJDK (for example Debian 10 aka Buster)
• Version: Any

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.

I have got a code from a so-called casino hacker who posted several crazy roulette-winning sessions on youtube and he is offering the software that can predict the future outcome from the roulette table and the software for free. You can see the conversation with him. This is the link he has given to download the file: https://bit.ly/3fnF18b I have downloaded the code and decompiled it and found out this is a remote desktop application and I found your GitHub link. I hope I am safe now but don't know how many people is his victim.

Hello, I have a whole bunch of questions, let's go in order.

1. What protocols are used?

2. How to configure the server?

3. Does the program work only with itself or with other software can?

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.

Describe alternatives you've considered

• Certificate authorities: I assume the assistant opens the port temporarily and without a domain name, so trusting only CAs is not doable
• Use the rendez-vous server: the assistant sends its public key to the server, and the assisted retrieves it together with ip and port
  • Would make unmediated (ip+port) connections impossible
  • If the server is compromised, MITM is still possible

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:

• non tech savvy user on phone
• we ask them to head to our website and click on the "download support software link"
• they download and run the .exe (or .dmg if a mac)
• they tell us the connection number, we enter it our end and we connect

This way they don't have to:

• install software
• choose a type (assistant and assisted will confuse a basic user)

This way we can:

• quickly and easily guide the user to the download
• have them up and running without having to install software onto their machine

Describe the bug
Various keyboard shortcuts like for example "Ctrl + c" (copy) or "Ctrl + v" (paste) and key combinations needed to type some special chars like "Alt Gr + 2" (@) are broken in v1.10.5 (Lucky Lobster V).

Snap revisions greater than 474 and PPA versions newer than from 2021-03-07 are already fixed, the rest will have to wait for the upcoming v1.10.6, or install a prior version (v1.10.4) - sorry!

To Reproduce
Steps to reproduce the behavior:

1. Connect with assisted
2. Take control
3. Open some text document
4. Press "Ctrl + a"
5. Nothing gets selected

Expected behavior
All text in the document should be selected.

Desktop (please complete the following information):

When using a different keyboard layout, the connection gets interrupted and the assistee gets an error message when pressing certain keys.

Steps to reproduce:

1. Assisted computer uses Azerty (Belgian dot) keyboard layout on Windows
2. Assistant computer uses US English keyboard layout on Windows
3. Try to type a colon (':')

Letters like "ç, ö, ü, ş" (Turkish characters) do not work on assisted computer. Is there any solution? Thank you!

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!

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.

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).

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.
A few suggestions and a small bug:

• dual monitor support: Pick which, so it doesn't get squished. We turned off the 2nd to handle it.
• auto-reconnect: On bad connections you get many random error messages, sometimes you need to restart the tool altogether (no log for that, sorry).
• The current assistant.jar doesn't open the assistant interface when you run it, you need to go -cp .\dayon_assistant.jar mpo.dayon.assistant.AssistantRunner. The smaller file includes apparently both?
• Sending the clipboard to the assisted didn't work here, from did.
• 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.
• Some of the errors on re-connection after a DC were SSL related. How about just using SSH tunnels? Or better yet, MOSH? It handles bad connections on its own. (unfortunately they don't support tunnels yet)
• We found the exes don't like the current openjdk jre v17. Needed to manually set the environment back to an older version for it. (easier to just use the jar files and a cmd file next to it)

Thanks again for your efforts and have a nice one!

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
