How can I make the VPN Client installed on CentOS 7 establish a connection automatically on boot?

Scope:

Barracuda VPN Client for Linux installed on CentOS 7 (may be applicable to other flavors)

Answer:

1. Install and configure the Linux VPN Client in accordance with the TechLibrary.

Installation:

https://techlib.barracuda.com/display/BNACV34/How+to+Install+the+Barracuda+VPN+Client+for+Linux+and+Mac+OS+X

Note: In CentOS, the install directory will be /usr/local/bin, not /usr/sbin as stated in the TechLib. Run 'which barracudavpn' on the CLI to confirm.

Configuration:

https://techlib.barracuda.com/display/BNACV34/How+to+Configure+the+Barracuda+VPN+Client+for+Linux+and+Mac+OS+X

2. Edit the /etc/rc.local file to run the VPN client at boot.
a. If using x.509 certificate authentication, add the line:
/usr/local/bin/barracudavpn -sk <cert password> &

b. If using MSAD authentication, add the line:
/usr/local/bin/barracudavpn -s --login <username> --serverpwd <password> &

c. If you would like to log output for debugging, include the "v" flag and specify the log file, as in the example below (for x.509 authentication):
/usr/local/bin/barracudavpn -svk <cert password> > tmp/barracudavpn.log 2>&1

d. For other options and configuration examples, run 'barracudavpn --help' on the CLI.
