Popub

Publish a service from localhost onto your server.

Scenario

If you have a web service, a game service, an SSH service, a VNC service, or any TCP service at your home computer. Your home computer is behind NAT and don't have a public and static IP address, but you want your friends to connect to your service.

If you operate another computer or server, which has a public or static IP address, you can run Popub there, to relay the data between your home computer and your friends, so that your service is made public accessible.

Building

Download the source code, and the latest Go.

On your home computer, type:

cd popub-local
go build

On your server machine, type:

cd popub-relay
go build

Running

Assume you have a web service at localhost:80, you want to publish it as my.server.addr:8080, and you want to use my.server.addr:46687 to communicate between your home computer and your server machine.

On your home computer, type:

cd popub-local
./popub-local localhost:80 my.server.addr:46687 SomePassword

On your server machine, type:

cd popub-relay
./popub-relay :46687 :8080 SomePassword

Note: The password is for authorization only, your traffic is not encrypted.
