Updating Unmanaged Units or NG Control Centers

Updating Units or NG Control Centers Using SSH

For speed reasons, Barracuda Networks recommends using this method of updating for all appliances in general, especially for those based on a flash drive or slower hardware.

Step 1: Copy

Before copying the package onto the unit as described below, make sure that there is no old minor release or patch package lurking within the /var/phion/packages/ directory. The directory must not contain any files.

Although the /var/phion/packages/ directory must be empty, it still contains the subdirectories: kl, os, ph, sa, tgz. These don’t affect the updating process. Furthermore, there must not be a whitespace character within path or file name of the package.

•Copy the update package onto your firewall system into the /var/phion/packages/ directory of the respective unit.

To get the file onto the unit, you may use the Send File button within the built-in SSH client of Barracuda NG Admin. Don’t forget to change the directory first using cd /var/phion/packages/.

Step 2: Update

Start the update sequence by executing phionUpdate from the shell.

No more interaction is necessary. Wait until the update is finished. Depending on the hardware, it will need from 15 minutes on the fastest appliances up to 60 minutes on the flash appliances.

Do not interrupt the update procedure. During update, the unit boots several times and due to this, the connection will be terminated. Whether the update process has been successfully finished is confirmed by output on the console, log messages, and firmware version and status displayed within Control > Licenses.
