fix(cyberghost): update cyberghost servers list

[y0hnn]

Cyberghost servers list is not up to date. For example, impossible to connect to hosts in Vietnam. But it seems the Cyberghost API used is not available anymore. For now, I just updated the list with a small script doing a dig on the hostnames, and putting every A records inside it. You can check it:

const fs = require('fs');
const dns = require('dns');
const path = require('path');

// Read the JSON file
const filePath = path.join(__dirname, 'cg.json');
const data = JSON.parse(fs.readFileSync(filePath, 'utf8'));

// Function to perform DNS lookup and update IPs
const updateIPs = async (hostname) => {
    return new Promise((resolve, reject) => {
        dns.resolve(hostname, 'A', (err, addresses) => {
            if (err) {
                console.error(`Failed to resolve ${hostname}:`, err);
                return resolve([]); // Resolve with an empty array on error
            }
            resolve(addresses);
        });
    });
};

// Function to process each server entry
const processServers = async () => {
    for (let server of data.cyberghost.servers) {
        console.log(`Processing ${server.hostname} for ${server.country}...`);
        const updatedIPs = await updateIPs(server.hostname);
        if (updatedIPs.length > 0) {
            server.ips = updatedIPs;
            console.log(`Updated IPs for ${server.hostname}:`, updatedIPs);
        } else {
            console.log(`No IPs found for ${server.hostname}.`);
        }
    }

    // Write the updated JSON back to the file
    fs.writeFileSync(filePath, JSON.stringify(data, null, 2), 'utf8');
    console.log(`Updated JSON saved to ${filePath}`);
};

// Start the process
processServers().catch(error => {
    console.error('Error processing servers:', error);
});
