Network notifications

Do you run a router that is actually a general purpose computer?
Do you want to know of devices comings and goings?

Then this project is for you!

Functions kind of like ip neigh by querying the kernel routing tables (rtnetlink https://man7.org/linux/man-pages/man7/rtnetlink.7.html) and essentially returning changes in state 'liveness'.

E.g

If a device suddenly goes from "Failed" resolution to "Reachable" then that notification is passed to the client via golang RPC.

Instructions

Building:

mkdir bin
go build -o bin ./...

Generate server/client keys

ssh-keygen -t ed25519 -f ./id_ed25519

Start the server and then connect to it with the client.

./client --address 10.0.0.1:3232

Features

• Gives events of devices becoming live on the network
• Has a client to display notifications via Dbus (dunstify)

Todo

• Client side 'labelling' of devices to allow for friendly names to be applied
• Use unix sockets to allow ls like network query
