Using the Barracuda Network Connector with Linux


Using the Network Connector with Linux

The Network Connector is available for use with Linux 2.4 or higher integrated with the TUN/TAP driver.

No separate client software is needed to connect from Linux systems to the Network Connector service, since most modern Linux distros already contain the required support in the OpenVPN NetworkManager-openvpn packages. However, a configuration file must be installed in order for the system to connect to the Barracuda SSL VPN.

Step 1. Install OpenVPN NetworkManager

If it is not already installed on your system, install OpenVPN NetworkManager. Depending on your Linux distribution, you may need to do this via one of the following methods:

  • Deb based Linux distributions (Ubuntu, Debian,...) In a terminal enter: sudo apt-get install network-manager-openvpn
  • RPM based Linux distributions (Redhat, SUSE,...) – In a terminal enter (as root): yum install NetworkManager-openvpn
  • Arch: sudo pacman -S NetworkManager-openvpn

Step 2. Download Client Configuration File

Download and save the client configuration file for the network connector:

  • Log into the SSL VPN web interface.
  • Go to the RESOURCES > My Network Connector page.
  • Next to the LAN1 Connector, click on the More... link next to the client configuration file.
  • Select Download Client Configuration file from the list.
  • Save and extract the downloaded file to the users home directory. E.g.,$HOME/SSLVPN.

Step 3. Configure Network Manager

Configure the Network Manager applet on your Linux system. Exact steps may vary based on your particular Linux distribution, but the resulting settings should be equivalent.

  • Left-click on the Network Manager entry on your Linux system panel and select VPN Connections > Configure VPN.
  • Click Import.
  • Select the Linux ovpn configuration file. E.g., $HOME/SSLVPN/linux-.ovpn
  • Enter the Username and Password.
  • Click Save.

Step 4. Initiate the Connection

Initiate a secured connection through the Barracuda SSL VPN:

  • Left-click on the Network Manager entry on your Linux system panel and select VPN Connections > Name-for-your-VPN-Connection.
  • An animated icon will appear while the connection is being made.
  • When connected, the icon will change to show a padlock.

Emby Media Server | Arch Linux

Prerequisite:I have tried to install Emby directly from the Arch package repositories, but for whatever reason, permissions for the emby service user were not allowing emby to access the media file locations. Now that I have used it a little bit, Docker seems to be the best, and easiest way, to get Emby up and running reliably. Below is my experience running through the emby installation process. Most of it comes from the GitHub tutorial, but I've added my take and what I've done to resolve certain issues.Note: The following install was done on an Arch Linux box, running the most recent kernel, which at the time was 4.3.3.-2-ARCH.You can get he full GitHub installation guide from herePrerequisite:First, make sure that you have a working Docker instance:sudo pacman -S docker Now, start the docker service:sudo systemctl enable docker sudo systemctl start docker Your docker container should now be running, and it should startup after each reboot of your system.

I always grab one from one of the US mirrors, but they have a Torrent file as well.Now lets create the install media:# sudo dd bs=512 if=/location/of/your/iso_file of=/dev/sdx && sync This will take about 5 minutes to complete, but it will depend on the quality of the flash media.Install Arch:Boot to the USB drive that you just created, and select the first boot option.After the OS environment boots, take a look at the connected devices and determine where you will be installing Arch. If you know how large your target drive is, determining which device to use should be fairly straight forward.# lsblk Network Setup:If you are connect to yo…
