Basic Usage

Server Setup

Setup a basic server on a linux VPS (e.g. DigitalOcean droplet):

$ wget https://github.com/sshh12/hermes/releases/download/$VERSION/client-$VERSION-linux-amd64.tar.gz
$ tar -xzf client-$VERSION-linux-amd64.tar.gz
$ ./server

Change $VERSION to the latest release name.

Client Setup

Run a simple web server:

$ python -m http.server 8080

Download the latest client release, then:

$ ./hermes -server $SERVER_IP -save
$ ./hermes 8080 8000

This will forward all connections from $SERVER_IP:8000 to localhost:8080 without needing to port forward on the client network.

or use this syntax for multiple tunnels:

$ ./hermes 5000 5001 3000 3001

This will forward $SERVER_IP:5001 to localhost:5000 and $SERVER_IP:3001 to localhost:3000.

TLS Usage

Server Setup

$ openssl ecparam -genkey -name secp384r1 -out server.key
$ openssl req -new -x509 -sha256 -key server.key -out server.crt -days 3650
$ ./server

Client Setup

$ ./hermes -use_tls -tls_skip_verify -save
$ ./hermes 8080 8000
