USB dongle server: software and hardware solution.

A USB dongle server is a useful tool to overcome restrictions of accessing remote USB license dongles. There are two options available: using software or hardware. Read on to find out more.

The hardware option involves the use of a dongle server. The dongle server makes your USB dongle available across your network. When using a dongle server, it is not necessary to have the license dongle connected to the client; the connected client can access the protected data directly.

The use of a dongle server is quite limiting in that only one user can access the dongle at a time in a typical point-to-point network connection. There is a more versatile and user-friendly option in the form of Donglify – a software alternative that allows you to redirect USB security keys over the Internet.

USB key server software

Donglify eliminates the connection limits that exist when using a dongle server. Using advanced port redirection technology, Donglify allows you to connect a licensed USB dongle to one computer, and then share that with multiple users over Wi-Fi, Internet or Ethernet. No additional hardware is required.

Getting started with Donglify

Step One:
To use Donglify you have to sign up by creating an account from the Donglify website. Once you have successfully created your account, you will be able to download the dongle server software.

Install the application on the device server – this is where the physical dongle will be attached. Also install the software on all the client machines that require remote access to the USB dongle.

Step Two:
Start Donglify and log in to your account when prompted.

Step Three:
In the window that appears after login, locate the "PLUS" icon. Click this to reveal a list of available USB dongles that can be shared with the client machines.

Take note of the "Multi-connect" or "Single-connect" options listed next to the USB dongle. Select the option as per your requirements. The "Multi-connect" option allows you to have multiple concurrent connections to the USB key dongle. Single connect only allows a single client connection at a time.

Step Four:
Click the radio button next to the USB dongle you want to share to select it, then click "Share".

Step Five:
On all the client machines, launch Donglify and sign in to your account. When the application launches you’ll see a list of devices that are available. Simply select the one you want to connect to, and click "Connect".

That’s all it takes. Donglify becomes a reliable USB key server in five simple steps. Now your USB key can be accessed from anywhere on your network.
