Overview

The VNC Password feature in zMan Director allows administrators to configure password-based authentication for remote VNC access to managed zTC devices.

This functionality helps secure remote device access by requiring authentication before establishing a VNC session.

VNC Authentication

When VNC access is enabled for a managed zTC device, a VNC password may be configured to restrict unauthorized remote access attempts.

Administrators can use VNC authentication to:

• Secure remote desktop access
• Restrict unauthorized VNC sessions
• Support remote troubleshooting operations
• Provide controlled remote support access

---

Remote Device Access

VNC access may be used during:

• Remote troubleshooting
• Device support operations
• Remote administration
• User assistance sessions

Availability of VNC connectivity depends on:

• Device connectivity status
• zDM communication availability
• Network accessibility
• Deployment configuration

---

Security Considerations

Administrators should use secure password management practices when configuring VNC access.

Recommended practices include:

• Using strong passwords
• Limiting password sharing
• Rotating passwords periodically
• Restricting VNC access to authorized administrators

---

Operational Notes

VNC connectivity behavior may vary depending on:

• WAN or LAN deployment mode
• zDM configuration
• Firewall policies
• Remote network accessibility

Some deployment configurations may require additional network or tunnel configuration for remote VNC access.

---

Troubleshooting

If VNC access is unavailable:

• Verify the zTC device is online
• Verify zDM connectivity
• Confirm network accessibility
• Verify remote access configuration
• Confirm password authentication settings

---

Notes

• VNC functionality depends on active device communication through zDM.
• Some deployment models may require additional WAN or tunnel configuration.
• Authentication behavior may vary depending on deployment architecture.
