Evil Portal

Evil Portal Setup Steps

  1. Configure portal settings in web UI
  2. Verify ESP has IP address before starting
  3. Use appropriate URLs:
    • Desktop: domain.local/login
    • Mobile: include "https://" in portal URL
  4. Note: If redirecting to MSN, you're likely connected to actual internet instead of the ESP portal

Connecting to the Evil Portal

If you're using the Evil Portal feature, note the following:

  1. Connect to the Evil Portal AP: Instead of connecting to "GhostNet," connect to the Evil Portal's Access Point (AP). The password for the Evil Portal AP is the same as the SSID.
  2. Web UI Replacement: When the Evil Portal is active, the normal web UI is replaced. You won’t have access to the web UI until the board is restarted.
  3. Refreshing Access Points: If "GhostNet" still appears after activating the Evil Portal, turn your device’s Wi-Fi off and on again to clear cached networks.

Tip: Windows and other devices sometimes cache network access points, so refreshing your Wi-Fi can help display the correct AP.

Common Portal Issues

  • Desktop Issues:
    • Auto-redirect to MSN: ESP using actual internet DNS instead of portal
    • Failed to fetch: Check portal configuration
  • Mobile Issues:
    • "Header fields too long": Add "https://" to URL
    • CSS display issues: Known limitation on mobile
