ip-auth

a web api for allowing ips on certain ports using links and UFW on linux, it also comes with a client to automate authentication on servers and clients.

Installation

If you are using the server source don't forget to install express using npm install express.
This app works with UFW so install it on your server: sudo apt-get install ufw sudo ufw allow ssh sudo ufw enable
Run server as ROOT or with sudo to access your UFW firewall.
Make sure to create server certificates for https (since the server is only https): openssl req -nodes -new -x509 -keyout server.key -out server.cert

Usage

With Binaries

Using server binary you don't need any arguments just the regular config.json file should be enough, you can access binaries here

{
    "portos":{
        "openvpn":8080      // Define proto name and target port (Here we are allowing our ip for ovpn server running on port 8080)
    },
    "ip":"",        // Your server IP
    "port":3000,        // web service default port
    "key":"",       // Client authentication key
    "timeout":5000,     // How many seconds an ip will be timed out
    "timer":20000       // How often the server check for clients
}

Using the client there are several arguments to launch your app with:

proto: the proto name you defined in protos of your server
ip: target server IP
port: target server Port
key: target server authentication key

Without binaries

For Server

There is not much difference, just follow these steps:

Install express using npm install express (required for server)
Run server/client using node main.js

For Client (Access using https request or open on web browser)

If you want to manually use the link try: https://IP:PORT/key/YOUR_KEY/proto/YOUR_PROTO
If you cannot access your ip directly or want to allow someone's else ip without giving them the key, do it using https://IP:PORT/key/YOUR_KEY/proto/YOUR_PROTO?ip=1.1.1.1 syntax
