gofer

Gofer

Gofer (GOfer Files Express Receiver) is a file transporter written in Golang.

It's now just a toy, do not take it seriously. You are expected to use something like scp or, better, rsync in the real world.

Build

You should build it by yourself, to get an unique set of TLS certificates (to protect the security of file transporting).

$ sh static/certs/generate_cert.sh
$ go build -o gofer.out ./cmd/main.go

Usage

gofer <send|recv> [-f=FILE] [-m=MESSAGE [-i INFO]] <-s|-c>=ADDRESS

 recv: receive things.

    	path of BiG_FILE to send (Only for <gofer send>)
  -c ADDRESS

  -i INFO
