How to Update the Barracuda NG Firewall or Control Center via SSH

  • Last updated on

This article provides instructions on how to update a Barracuda NG Firewall or Control Center via SSH.

It can be faster to update a system via SSH, especially for systems that are based on a flash drive or have slower hardware.

To update your system via SSH: 

  1. Make sure that the /phion0/packages/ directory does not contain any files such as an older minor release or a patch package. The directory should only contain the kl, os, ph, sa, and tgz subdirectories.
  2. Copy the update package or patch into the /phion0/packages/ directory on your NG Firewall or Control Center. The package path and file name must not contain whitespace characters.
  3. In the Barracuda NG Admin SSH client, you can also transfer the file onto the system by changing into the /phion0/packages/ directory and clicking Send File.

  4. Type phionUpdate.

Wait for the update to finish. Depending on your system hardware, the upgrade can take anywhere from 10 minutes (on a fast system) to 60 minutes (on a flash unit). The Barracuda NG Firewall will reboot after the upgrade process.

 Do not interrupt the update. During this process, the system boots and disconnects several times. As soon as the system is successfully updated, the combined major, minor, and build number for the new version is displayed on the console. For example:

 Barracuda NG Firewall release 6.0.x-xxx

 You can also log back into the system using SSH or Barracuda NG Admin. On the Dashboard page, you can confirm the system version and status.
