Support hostnames when specifying hosts #24

Open colthreepv opened 4 years ago

colthreepv commented 4 years ago

I would like to leverage hostname resolution to not have to write IP by hand in the command invocation.

At the moment doing this,

any service on port 3333:

docker run --rm -p 3333:8000 jwilder/whoami
Listening on :8000

server:

shapeshifter-dispatcher --server --state state_srv -transparent --transports obfs4 --orport 127.0.0.1:3333 --bindaddr obfs4-127.0.0.1:2222 -logLevel DEBUG -enableLogging

client: 

shapeshifter-dispatcher --client --state state_cli -transparent -target 127.0.0.1:2222 -transports obfs4 -proxylistenaddr localhost:9443 -logLevel DEBUG -enableLogging -optionsFile obfs4.json

Testing tunnel:

curl localhost:9443
I'm da23b149f740

So it works, but replacing 127.0.0.1 with localhost breaks tunnelling in many parts.

Is there a single point where this could be added? I could provide a PR

Opened library issue on shapeshifter-ipc#1

It would be nice to see a go package which leverages resolvconf for dns resolution actually. So that the command just passes the string argument upon exec, and pushes the resolved name to the parameters as an 'interface{}' pointer.
