netlink-notify
==============

**Notify about netlink changes**

This runs in background and produces notifications whenever a netlink event
is received. Notifications look like this:

A device is down:

![Device down](screenshots/down.png)

A device is up:

![Device up](screenshots/up.png)

A device received an IP address:

![Device received IP address](screenshots/ip.png)

A device received an IPv6 address:

![Device received IPv6 address](screenshots/ipv6.png)

A device disappeared:

![Device disappeared](screenshots/away.png)

Requirements
------------

To compile and run `netlink-notify` you need:

* [systemd](https://www.github.com/systemd/systemd)
* [libnotify](https://developer.gnome.org/notification-spec/)
* [linux](https://www.kernel.org/)
* [markdown](https://daringfireball.net/projects/markdown/) (HTML documentation)
* [librsvg](https://wiki.gnome.org/Projects/LibRsvg) (convert icons from SVG to PNG)
* [oxipng](https://github.com/shssoichiro/oxipng) (optimize PNG icons)

Some systems may require additional development packages for the libraries.
Look for `libnotify-devel` or similar.

Build and install
-----------------

Building and installing is very easy. Just run:

> make

followed by:

> make install

This will place an executable at `/usr/bin/netlink-notify`,
documentation can be found in `/usr/share/doc/netlink-notify/`.
Additionally a systemd unit file is installed to `/usr/lib/systemd/user/`.

Usage
-----

Just run `netlink-notify` to run it once. A systemd user service can be
started and/or enabled with `systemctl --user start netlink-notify`
or `systemctl --user enable netlink-notify`.
