Tunnel Sevice

This is an experimental tunnel service for http, it supports authentication and load balancing

Installation

npm -g install @eslym/tunnel
mkdir tunnel-service
cd tunnel-service
ssh-keygen -f server_key.pem
mkdir users

Configuration

The directory for user configuration

users
└── username.yml

The extension may be yml, json or json5, the content of the file is like:

password: "" # Bcrypt hash
keys:
  - ssh-rsa ... # ssh keys
domains: # Allowed domains
  - "**" # Catch all
  - "example.com" # Match exact
  - "*.example.com" # Match wildcard
  - "**.example.com" # Catch all including subdomains

The user must have either key or password.

Start the service

tunnel-service -H $HTTP_PORT -s $SSH_PORT -k ./tunnel.pem -a ./users

Connect the service

ssh -R $BIND_DOMAIN:$BIND_PORT:$LOCAL_ADDR:$LOCAL_PORT username@$SERVICE_HOST -p $SSH_PORT

The port forward is just virtually bound, the BIND_PORT is either 80 or 443, use 80 when the local server is serving http, use 443 when local server is serving https.
