Haskell version of hole
When I visit raspberry pi' ssh server on some places, I must set port forwarding on the home route, and set a dynamic DNS. If the route is not your's, you will helpless.
I think it may have another way, so I try ssh port forwarding ssh -CfNgR remote-port:localhost:local-port user@remote, then visit the remote-port.
The hole is an other way similar ssh port forwarding.
On the global server create a holed, and the target host start hole.
Last you can visit the holed to replace the real server.
The hole suit the situation: A(private) can connect B(global), C(private) can connect B, but B can't connect C, B can't connect A, and A can't connect C.
The hole support protocol tcp tcp6 udp udp6 and unix socket.

- On server.
holed -H tcp://server:port --addr tcp://server:portout
- On local mathine
hole -H tcp://server:port --addr tcp://localhost:portin
Then you can access the local server via. tcp://server:portout
- On server
holed -H tcp://server:port --addr tcp://localhost:portin --use-remote-to-local
- On local machine
hole -H tcp://server:port --addr tcp://localhost:portout --use-remote-to-local
Then you can access the remote server via. tcp://localhost:portout
