kybonet 0.0.9

Software KVM switch over the network with encryption (keyboard and mouse only, no video).

Kybonet - software KM switch with encryption!

Description

Share your keyboard and mouse connected to a computer over the network!

This tool allows to share your input devices with many computers in the same network (one at a time). You can switch from one computer to the next one with a configurable hotkey (by default F7).

How does it work?

The host computer (the one with the keyboard/mouse) runs the server, and every computer where you want to use that keyboard run the client.

To keep things easy, there is no point-to-point connection here, but a zmq publish/subscribe scheme. The server'll publish the keyboard events encrypted with the public key of the selected client, so only that client'll be able to decode them. When pressing the hotkey, the server'll start using the public key of the 2nd client to encrypt the events. Now only the 2nd client'll be able to decode them.

Setup the client

• Step 0 - (optional) Create a venv.

python3 -m venv venv
. venv/bin/activate

• Step 1 - Install the required packages.

pip install kybonet

• Step 2 - Generate public/private keys pair (one in each client).

# generate
kybonet-keygen
# Copy public key to the server
scp <public-key.pub> <user>@<server>:<path>/

• Step 3 - Run.

kybonet-client <server-ip> -p <port> -i <private-key>

Setup the server

• Step 0 - (optional) Create a venv.

python3 -m venv venv
. venv/bin/activate

• Step 1 - Install the required packages.

pip install kybonet

• Step 2 - List the available devices and identify the ones you want to be shared:

kybonet-devices

Note: It's likely that you need to add your user to the input group in order to have access to the input devies. Check that with ls -las /dev/input and add it with usermod -aG <group> <user>. You'll have to login again so the change take effect.

• Step 3 - Open the default config file or get a copy of it (~/.local/kybonet/config.yml). Add as many clients as you want, with at least a name and the path to their public key (the hotkey field is optional). In case you don't like the default values, you can also assign the hotkeys you want to switch between clients and to exit the program.

• Step 4 - Run.

kybonet-server -p <PORT> -c <config-file>

Note: If the config-file is ommited, it'll be loaded from ~/.local/kybonet/config.yml. If you want a fresh start, remove it and when you run kybonet-server a new one'll be created.
