File transfer over parallel TCP, requires port-forwarding your TCP ports.
Heavily inspired from magic-wormhole and wormhole except it doesn't have the rendevous server, or the transit relay. It's not really anything like it, except that its file transfer over TCP with AES-128 encryption built over it. Here you can transfer a file using multiple TCP ports simultaneously.
Be sure to open up TCP ports 27001-27009 on your port forwarding. Also, get your public address:
$ curl icanhazip.com
X.Y.W.Z
Then get and run ptransfer with a 16 byte key for encryption/password:
$ go get github.com/sauravhiremath/ptransfer
$ ptransfer -file SOMEFILE -p ABCDEFGHIJKLMNOP
ptransfer automatically knows to run as a server when the -file flag is set.
$ go get github.com/sauravhiremath/ptransfer
$ ptransfer -server X.Y.W.Z -p ABCDEFGHIJKLMNOP
ptransfer automatically knows to run as a client when the -server flag is set.
For people that don't have or don't want to build from source and don't want to use the command line, you can build it for them to have the flags set automatically! Build the ptransfer binary so that it always behaves as a client to a specified server, so that someone just needs to click on it.
go build -ldflags "-s -w -X main.serverAddress=X.Y.W.Z" -o client.exe
Likewise you could do the same for the server:
go build -ldflags "-s -w -X main.fileName=testfile" -o server.exe
TODO
Note: This setup uses go1.15.2
Installing the dependencies in vendor
go mod vendor
Build the project to get the executable
go build -o build/ptransfer ./cmd/ptransfer
Run the project directly without build
go run cmd/ptransfer/main.go
Whitelisting Allowlist ports 27001 - 27008 in your firewall.
This is required only on sender side (it has to open connection channels to allow the client to connect)
Example usage with ufw (the default firewall tool used in ubuntu, I personally use it with arch too)
sudo ufw allow 27001:27008/tcp
