# mconnect
mconnect - KDE Connect protocol implementation in Vala/C

GLib and Gio should be available even on trimmed down systems. Vala is really
needed only at build time. Json-glib does packet parsing. Libnotify is
responsible for displaying shell popups.

# Building

Build dependencies (using package names as found in Fedora):

- vala
- glib2-devel
- gobject-introspection-devel
- libgee-devel
- json-glib
- gnutls-devel
- libnotify-devel
- gtk3-devel
- at-spi2-core-devel (and at-spi2-atk)
- meson
- pkg-config

or see `extra/travis-build` in the source tree for example installation
commands. Once build deps are in place, run:

    mkdir build
    cd build
    meson ..
    ninja
    ninja install
    # to set a custom installation directory run:
    #   DESTDIR=<somedir> ninja install

# Configuration

**NOTE**: manual configuration file is no longer needed

A sample configuration file is provided in source tree, see
`mconnect.conf`. It will get installed to `${datadir}/mconnect/`
(usually corresponding to `/usr/share/mconnect/`) by default. Once
`mconnect` starts it will pick the default file and make a copy of it
in user's config directory, specifically `~/.config/mconnect/`.

A device described in it's own group and listed in `main.devices`, has
to match exactly with incoming identity packets. However, since
`deviceId` is not known beforehand, neither shown in KDE Connect
Android application, only `name` and `type` are used for matching.

# Usage

mconnect comes are 2 separate programs, the daemon - `mconnect` and a D-Bus
client `mconnectctl`.

## The daemon

Start it by running:

```
$ mconnect -d
```

The daemon starts listens on `0.0.0.0:1714` for incoming UDP packets. Once an
identity packet (a sort of a handshake) is received, a connection to the
sender's address will be made. Known devices are cached in
`~/.cache/mconnect/devices`.

File sharing to a device requires TCP ports 9970-9975 to be open. Files shared
from the device are saved to `~/Downloads/mconnect/`.

## The client

List discovered devices:

```
$ mconnectctl list-devices
Devices:
    /org/mconnect/device/0    673ac2db27d2a331 - Motorola Moto G Maciek
```

Accept a device (previously done only through the configuration):

```
$ mconnectctl allow-device /org/mconnect/device/0
```

Show device details:

```
$ mconnectctl show-device /org/mconnect/device/0
Device 
  Name: Motorola Moto G Maciek
  ID: 673ac2db27d2a331
  Address: 192.168.1.103:1716
  Type: phone
  Allowed: true
  Paired: true
  Active: true
  Connected: true
```

Share a file/URL/text:

```
$ mconnectctl share-file /org/mconnect/device/0 <path>
$ mconnectctl share-url /org/mconnect/device/0 www.google.com
$ mconnectctl share-text /org/mconnect/device/0 'battery horse staple'
```


## DBus API

The API is not documented. Use D-Feet or busctl to introspect and invoke methods
manually.

## Gnome Shell

A Gnome Shell extension is available here:
https://github.com/andyholmes/gnome-shell-extension-mconnect or via the GNOME
extensions page: https://extensions.gnome.org/extension/1272/mconnect/


# Firewalls

It may be required to either temporarily disable the firewall or open up UDP
port 1714.

An example service definition for [firewalld](http://www.firewalld.org/) is
provided in `extra/firewalld/mconnect.xml` directory. The file needs to be
copied into `/etc/firewalld/services`.
