wormhole

Very fast and simple go program that transparently proxies any raw TCP connection from one TCP socket to another. The wormhole destination is the same every time and specified by flags at startup time.

installation

go get -u github.com/integrii/wormhole

usage

Just execute the binary from your terminal with a -? flag to see help that looks like this:

./wormhole -?
Usage of ./wormhole:
  -from string
    	The address and port that wormhole should listen on.  Connections enter here. (default "0.0.0.0:443")
  -to string
    	Specifies the address and port that wormhole should redirect TCP connections to.  Connections exit here. (default "127.0.0.1:80")

example

This opens a wormhole from all local interfaces on port 22 to 8.8.8.8 on port 2222.

./wormhole -from 0.0.0.0:22 -to 8.8.8.8:2222

You can now SSH to 127.0.0.1:22 and it will come out at 8.8.8.8:2222.

Docker example

docker run -d --restart=always -p 8000:8000 integrii/wormhole -f 0.0.0.0:8000 -t google.com:80
