This is my pet project to learn Golang and try to understand the GRPC protocol (with reverse engineering effort). The idea behind this project was to create a simple taskbar menu with the most crucial information from nordlayer status. Unfortunately, on linux Nord doesn't provide a GUI version (like on Mac and Windows).
The GRPC API is also not documented publicly, so all the work was done using package capture and trying random things.
On Fedora with GNOME desktop, you need to install AppIndicator and KStatusNotifierItem Support extenstion
- Displaying current status of connection
- Listing gateways
I am also planning to include an option to change gateways and a notification system about being offline, External IP address changes.
To build this application, you need to have make gcc libgtk-3-dev libayatana-appindicator3-dev protobuf-compiler
For some reason libayatana-appindicator packages are not available in Fedora, so i used Ubuntu in distrobox for development
Dependencies for Debian-based:
sudo apt install make gcc libgtk-3-dev libayatana-appindicator3-dev protobuf-compiler
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
go mod download
If you get error like
protoc-gen-go-grpc: program not found or is not executable
Check your GOPATH (most likely you don't have ~/go/bin in your PATH)
make build
This command will build pb.go files from protobuf files and build the application.
