# ManyPorts
This is a simple tcp proxy that's powered by ebpf router running in the kernel.
# How it works
The application has 2 parts.
- ebpf (kernel) - routes all network traffic to multiple ports to a single socket.
- proxy (userspace) - directs traffic to the appropriate backend.
See config.json for how the routing map looks like.
## How to regenerate bpf files
- Run `make deps` to install bpf2go tool.
- run `make generate` to generate the object files & go types.
## How to run
After generating all the bpf files, run `go run cmd/proxy/*.go`
## Versions
- Ubuntu, 20.04.4
