Fully Preconfigured Custom Installation

  • Last updated on

The silent.cmd setup is a comprehensive installation method, allowing you to fully preconfigure all Network Access Client settings remotely on multiple installation systems. The silent.cmd setup installs the Barracuda Network Access Client and its components and requires administrator rights on the target system. Only experienced system administrators should perform this method. 

Installation Using a silent.cmd File

Prepare the install file and execute an unattended customer setup.

Step 1. Prepare the silent.cmd File

Save the following to silent.cmd:

@echo off 
REM installs VPN-only version of NAC (VPN components + Virtual Adapter)
REM use "PROGTYPE=ENTEGRA" instead to also install NAC/Firewall components
start /wait BarracudaNAC.exe /clone_wait /s /v"/qr PROGTYPE=VPN REBOOT=Suppress"

REM uncomment to import custom application settings (e.g. VPN profiles)
REM reg import mysettings.reg

To install the VPN-only plus the credential provider, replace the install command in the script above with the following:

  • start /wait BarracudaNAC.exe /clone_wait /s /v"/qr PROGTYPE=VPN ADDLOCAL=CommonCore,DrvCudaVPN,x64VPN,x64CredProv REBOOT=Suppress"

To install the full client (ENTEGRA option) plus the credential provider, replace the install command in the script above with the following:

  • start /wait BarracudaNAC.exe /clone_wait /s /v"/qr PROGTYPE=VPN ADDLOCAL=CommonCore,DrvCudaVPN,x64VPN,DrvSPAC,x64Firewall,DrvProcmonD,x64CredProv REBOOT=Suppress"

CommonCore, DrvPhionVPN, and x64VPN are VPN components, DrvSPAC, x64Firewall, and DrvProcmonD are firewall components, x64CredProv is the credential provider.

To install the client on ARM systems, you must replace the "x64" part of any given component names with "arm64". For example: arm64VPN or arm64CredProv.

The registry file (mysettings.reg) is used for optional import of custom application settings (e.g., VPN profiles) as they can be found in HKEY_USERS\.DEFAULT\Software\Phion\.

This approach replaces unattended installations by using customer.inf files that might have been used in earlier versions (NAC 3.x/4.x).

To create this file, open regedit on a preconfigured machine, export the registry key as given above, and save it as mysettings.reg

NAC 5.x can read CA certificates from the Windows certificate store (folder Trusted Root Certification Authorities), where the desired certificate can be stored.

Step 2. Copy the silent.cmd File to the Setup Directory

  • Copy the silent.cmd file to the folder containing the BarracudaNAC.exe file.
Step 3. Execute the Installation
  • Execute the silent.cmd file to trigger an unattended customer setup.

After installing the client, you can connect and configure the settings. Continue with Getting Started.
