## Remote Assistance Service

Dayon! is an open-source and cross-platform (JAVA) solution that allows watching and controlling a remote computer. In this sense, it is very much similar to existing remote desktop solutions.

But I guess it's got some features that makes it valuable.

You'll find more details on this page.

## Features

### Easy Setup

Dayon! is dedicated to people who are quite new in the computer world. There's no need to set up the network (i.e., no firewall setup, no router configuration, no NAT setup) on their computer. Dayon! is acting there as a client connecting to the monitoring computer.

### Low Network Bandwidth

Dayon! is sending compressed and cached gray (up to 256 levels) pictures to minimize the network usage offering as much as possible a real-time experience over the Internet. Those pictures are far enough for monitoring and explaining the different menus, icons and discovering the computer setup, etc...

## Status (14)

Since release 1.9 (Promiscuous Potato), a portable "quick launch" version is available in addition to the conventional installation program. There are two separate "quick launch" Windows binaries, one for the assisted and one the assistant. They are called "quick launch", because they allow the assisted or assistant part to be run without prior installation (require the presence of an JRE, however). They are 100% compatible with the conventional Dayon! Versions. Since release 12 (Adorable Asteroid), similar portable versions are available for Linux as well.
Due to the lack of Apple hardware, the clipboard transfer feature could only be tested with Windows 10 and 11, Debian and Ubuntu - Feedback from macOS users would be very welcome!

## Rational

Marc Polizzi has developed Dayon! when he was living in the Philippines and was communicating with his family and friends back in Europe over Skype.

He didn't want them to set up their firewall, DSL/cable router and NAT and whatever else required for him to access their computer over a remote desktop connection. So he decided to implement something very simple in his spare time while also considering a low-bandwidth, high-latency network.

Several years later, I found this program on Sourceforge when I was looking for free cross-platform remote assistance solution. While using Dayon! to assist users running Windows 7 and later, I realised that it had some serious flaws. As the latest version (1.2) has been released back in early 2009, I decided to contact the author. With his consent I moved the source code of the project to GitHub in late 2016 and took over the further development.

By the way, Dayon! means "Come in!" in Visayas - a local Philippine dialect.
