UniKey Network Service

The NetUniKey service is an application that runs in the background and enables network connectivity for UniKey devices to operate over a network.

Install UniKey Network Service

To install the service, navigate to UniKey SDK\Network\Server\Network.Server.ia32 and run Install.exe as an administrator. A command-line window will pop up, as shown below.

command-line application

There are two options:

[A] Install the NetUniKey service and Run it now
[B] Uninstall the NetUniKey service

Input "A" (without quotes) and press Enter to install the service. After installation has been successful, the command-line window will close and the service will automatically run.

Uninstall UniKey Network Service

To uninstall UniKey Network Service, repeat the above steps, and input "B" (without quotes) to uninstall the service automatically. After uninstalling successfully, the command-line window will close.

UniKey Network Server Console

The UniKey Network Server Console is a tool to monitor client connections, configure settings, and manage black and white IP Lists.

Note: The UniKey Network Service must be running to use the UniKey Network Server Console.

To run the network server console, run "NetUniKeyServer.exe" from the directory UniKey SDK\Network\Server\Network.Server.ia32.

The four tabs in the "UniKey Network Server Console" window are Monitor, Service Manager, Black IP List and White IP List.


Under the Monitor tab, connected clients are listed with information including:

  • Client IP Address – IP address of the connected client
  • Computer Name – Computer name of the connected client
  • Mode - Working mode of a connected client.
  • HID – The HID of the client's UniKey device
  • GUID – A unique ID assigned to each connected client.

Users can click Refresh to update the list of connected clients.

Disconnect an IP

To disconnect a connection with the corresponding client, you can select that item, then click Kill or click Kill All to disconnect all connected clients.

Service Manager

By clicking the Service Manage tab, you can check the server's status and configure the server.

UniKey Network Server Console Service Manage tab

You can start or stop the Service and Network just by clicking the respective "Start" or "Stop" button. The green dot next to Service and Network indicate both of them are working properly. If the dot is red, it indicates that the corresponding function has stopped functioning.

Server Configuration

When the server has more than one IP Address, click the Server IP Address drop-down menu; you can select different IP addresses as the server's address, and define the connection port value.

UniKey Network Server Console Network stopped

Times limit(s) – defines a time interval (in seconds) that the server will check client connections. If the client has no response in that period, the server will close the connection. By checking the Auto Start option, you can let the service run automatically when the server starts. Clicking Refresh will update the server status, and then click OK to confirm all settings.

IP Blacklist

IP addresses listed in in the IP blacklist cannot connect to the server.

UniKey Network Server Console IP blacklist tab

To enable this function, tick the Enable Black List checkbox, and use Add and Delete to add and remove clients to/from the blacklist, respectively.

Blacklist an IP Address

By clicking Add, a Server window will popup. Input the start and end IP address range in the fields Start IP Address and End IP Address, respectively.

UniKey Network Server start and end IP address

Click OK to confirm these details; the IP address range will be added to the list.

UniKey Network Server Console IP address added to blacklist

To delete an entry from the list, select the item and click Delete. Click Refresh to update the IP blacklist.

IP Whitelist

IP addresses listed in the IP whitelist are the only IP addresses that can connect to the server. The configuration of White IP List is similar to the configuration of Black IP List (see #Blacklist an IP Address)

Client Configuration

In this part, we will describe how to configure the client computer, including working mode, access mode and server information. To set up the working mode and access mode there are two ways, by modifying the NetUniKey.ini file or by using the API. We will introduce NetUniKey.ini file modification first.

Navigate to the UniKey Network Client, located in the directory UniKey SDK\Network\Client

Libraries and Samples folder

There are two sub-folders:

  1. Libraries: Includes all UniKey libraries for various programming languages for clients.
  2. Samples: Includes all the samples for various programming languages for clients.

Configuration file

Open the Libraries folder and open the NetUniKey.ini file in a text editor of your choice.

NetUniKey.ini opened in Notepad

In this file you can configure your client's computer.

WorkingMode defines how the clients find UniKey hardware; there are 4 options:

  1. Client will only try to find a UniKey from a local computer.
  2. Client will only try to find a UniKey from a network.
  3. Under the default setting, client will first attempt to find a UniKey from a local computer, if not, then it will attempt to find a UniKey from the network.
  4. Client will first try to find a UniKey from the network, if not, it will attempt to find a UniKey from a local computer.

AccessMode defines how the client finds a UniKey from network; there are 3 options:

  1. Per IP address mode: indicates you can log in to UniKey (as a client user) once for one computer.
  2. Per process mode: indicates you can log in to UniKey for one application once, and you can run many applications that require a UniKey on one computer.
  3. Per thread mode: indicates you can log in to UniKey many times for one application and you can run many applications that require a UniKey on one computer.

ServerIP: Refers to the server's IP address.

ServerIP2: Optional, refers to the second server's IP address.

Port: The connection port number.

TimeOut: Send/receive time out displayed in seconds.

Alternative methods of configuration

Another way to configure the network monitoring tool is to use the respective library API, the steps are shown as below:

For the UniKey_Find function, you need to assign a value to lp1 and lp2 parameters. For example, in C this would be written as: retcode = UniKey_Find(&handle[0], &lp1, &lp2);

lp1 and lp2 are WorkingMode and AccessMode respectively. If you want to modify the WorkingMode and the AccessMode directly from the NetUniKey.ini file, please assign lp1 and lp2 a value greater than 5. The ServerIP in the NetUniKey.ini file should be the same as the server's IP address. Please modify the ServerIP according to the server's IP address.


The 105 error code is caused by a firewall. It is NECESSARY to close the firewall at both the server side and the client side in order to proceed.
