How to Troubleshoot and Fix KVM-410 LogServer Errors The D-Link KVM-410 Single Port KVM Switch over IP relies on a specialized LogServer utility to record system events, tracking administrator activities and user authentication histories. Because this network monitoring environment operates on a legacy framework—specifically utilizing the Microsoft Jet OLEDB 4.0 provider and Sun Java Runtime Environments (JRE)—it frequently encounters database locks, connection drops, and driver conflicts. Resolving these issues requires systematic verification of both the database pathways and system dependencies. 1. Database Connection and Driver Verification
The most common LogServer crash stems from missing database engine configurations or corrupted Access .mdb files.
Install the OLEDB Provider: Verify that the host operating system running the LogServer utility has the Microsoft Jet OLEDB 4.0 driver installed.
Run in 32-bit Compatibility: The Jet 4.0 driver natively operates in 32-bit spaces. For modern 64-bit systems, adjust the application’s launch execution properties to run inside a 32-bit subsystem.
Repair the Access Database: If the log utility drops information, close the application and navigate to its source directory. Open the underlying log database with MS Access and execute the Compact and Repair Database function to clear internal structural corruption.
Check File System Permissions: Right-click the folder hosting the LogServer file. Grant full read, write, and execute permissions to the active user account so the database engine can freely write temporary lock files. 2. Network Port Allocation and Encryption Adjustments
Because the device handles data over IP networks, firewall rules and port availability can block log transfers.
Unblock Local Ports: Add custom firewall rules allowing traffic across port 5900 (for standard VNC/KVM transport) and the proprietary ports assigned to the LogServer.
Review Browser Cryptography: The KVM-410 requires browsers to support 128-bit data encryption. Ensure your client browser allows legacy 128-bit SSL/TLS ciphers for proper handshake completion.
Assign Static IPs: Do not rely on DHCP for the logging server host. Set a permanent, static local IP address to ensure the KVM-410 switch does not lose its target destination during periodic IP lease updates. 3. Java Runtime Environment Configurations
The remote client relies heavily on Java infrastructure to map and visualize incoming logs.
Downgrade to Compatible JRE: Modern Java versions often block legacy applets. Use the recommended Sun Java 2 (v1.4 or higher) package to ensure system calls execute reliably.
Bypass Code Signing Restrictions: Open your operating system’s Java Control Panel, select the Advanced tab, and toggle the setting to bypass signed code certificate revocation checks. This stops unexpected console connection failures.
Add Site Exceptions: Add the explicit HTTP/HTTPS IP addresses of both your KVM-410 switch and your LogServer host to the Java Control Panel Exception Site List to prevent security sandbox blocks. 4. Hardware and Memory Recovers
Persistent communication dropouts can mean the local hardware stack is overloaded or needs a reset.
Re-power the Hardware: Disconnect the network and power leads from the hardware interface. Let the appliance drain completely for 30 seconds before reconnecting to clear the local buffer cache.
Purge Active Sessions: The KVM-410 caps its active ecosystem at 16 user accounts and 4 concurrent logins. Clear inactive remote sessions through the admin panel to free up system threads for incoming log files.
