Synergy Business Common Questions & Security/Compliance

Updated

Product: Synergy 1 Business / Synergy Enterprise
Operating System(s): All

Network & Firewall

Which Port Does Synergy Use?

  • Default Port: TCP 24800

  • Firewall Configuration: Ensure both inbound and outbound traffic on port 24800 is allowed for each Synergy‐enabled machine. This allows the client machines to connect to the Synergy server.

Does Synergy Work Offline?

  • Offline Operation: Yes. Synergy requires only a local network (LAN) to share keyboard/mouse.

  • Initial License Activation: An internet connection is typically required unless you already have an offline‐capable license key.

Logging & Debugging

Enabling Debug Logs

  1. Open the Synergy UI and look for any “Logging” or “Advanced” settings.

  2. Switch the log level to Debug or Verbose (depending on your Synergy version).

  3. Reproduce the issue so Synergy captures detailed logs.

Log File Locations

  • Windows:

    shell %Users%/YourUsername/synergy.logs

  • macOS & Linux:
    Varies by distribution and Synergy version. Usually within ~/.local/share/Synergy/logs or a similar path.

Check logs for errors related to connectivity, licensing, or configuration. This is often the first step in troubleshooting any Synergy issue.

Migrating or Backing Up Configuration

  1. Configuration File (Windows)

    • Typically located at:

      shell %LOCALAPPDATA%\Synergy\synergy-server.conf

    • To replicate settings on another machine, copy this file to the same location on the target system.

  2. Registry (Windows‐Only)

    • Open Registry Editor and navigate to: HKEY_CURRENT_USER\SOFTWARE\Synergy

    • Export the key to a .reg file and import it on another Windows machine to restore the same settings.

This process helps you quickly move your server configuration (e.g., screen layout, hotkeys) or user preferences from one system to another.

Deploying Updates

  • No Built‐In Remote Updates: Synergy 1 does not include a specialized remote update or patching feature.

  • Use Your Existing Toolset: Admins can rely on software deployment/patch management solutions—e.g., Microsoft SCCM, Intune, or similar—to push newer Synergy installers or patches.

  • Silent/Unattended Flags: When deploying updates, you can use the same silent installation parameters (e.g., /qn for MSI installs) as you do for initial installations.

Security & Compliance

How Do I Disable Clipboard Sharing for Security Compliance?

You can disable clipboard sharing from the Server Configuration:

  1. Open Synergy Server Settings (GUI) or edit your synergy.conf file.

  2. Look for the “clipboard sharing” option and uncheck it (GUI) or set the corresponding parameter (e.g., clipboardSharing=false) in the config file.

  3. Restart Synergy to apply the change.

Does Synergy Support Encryption for Data Transmission?

Yes. Synergy 1 supports TLS/SSL encryption for data transmitted between server and client.

How Do I Lock Down Settings So Users Cannot Change Them?

Synergy 1 does not offer a built‐in “lockdown mode,” but you can limit changes by combining two approaches:

  1. Option 1: Multi‐User Support

    • Install & Configure Synergy under an admin account.

    • Run Synergy under a non‐admin account.

    • This can disable certain UI elements for standard users (though it’s not fully locked down).

    Cons: Users might still edit config files in their local profile.

  2. Option 2: Central Config File

    • Store synergy.conf in a read‐only location.

    • Point each client to that config file (for advanced users, you can specify a config path or flag).

    (See “image-20250310-194415.png” for an example folder structure.)

    Pros: Harder for users to modify core settings.
    Cons: Still not a complete lockdown if the user can gain write access or has local admin rights.

Quick Reference

  • Port: 24800 (TCP)

  • Encryption: TLS/SSL available

  • Offline Mode: Possible after license activation

  • Logs (Windows): %Users%/YourUsername/synergy.logs

  • Config File (Windows): %LOCALAPPDATA%\Synergy\synergy-server.conf

  • Registry Key (Windows): HKEY_CURRENT_USER\SOFTWARE\Synergy
