Common Issues

Scans are failing instantly or showing errors

This is usually due to Nmap missing from the system PATH.

1. Open a terminal or command prompt.
2. Type nmap --version.
3. If the command is not found, reinstall Nmap and ensure Add to PATH is selected.
4. Restart Surveyor.

No hosts are being discovered

Check the following common blockers:

• Firewall rules: Ensure your local firewall isn’t blocking the scanning process.
• Network isolation: If you are on a guest Wi-Fi or isolated VLAN, discovery will be limited.
• Permissions: Some scan types, such as OS detection, require administrator privileges.
