The GUI ScreenIO Network ClientWhat is the Network Client? Its a small program that runs on a remote workstation and allows the user to run jobs on a Server in a secure and controlled way. It allows you to run most GUI ScreenIO applications, unchanged, as client/server applications over any TCP/IP network (including the Internet). The client can be configured so that it connects and automatically launches a specified server application when the user launches the client. This makes it look and act exactly as though your application was running locally. IUse File/Connect to... on the main menu and select the server from a list, or to enter a new server.. Once connected, the client displays a menu of available applications. This shows a client that is connected to our test server, displaying the menu items for this user. You launch the application of your choice by pressing its button. The menu closes, then the first panel of your application appears. From that point on, it looks and feels exactly as if it were running locally. When you close your application, the menu will be redisplayed so that you can select another application or exit (log out). Pad-Lock symbol indicates a Secure encrypted connection when Locked symbol, shown (above) and an unencrypted connection when the Unlocked symbol is shown. Not running windows?If you run Linux or Mac you may still be able to run the Network Client. See this page for how to get the Client to run under Linux or Mac systems. LicensingThe GUI ScreenIO Client is licensed on a per-computer basis. Secure Server OptionIf you purchase the Secure Server Option when you purchase your Server license, All CLIENTS that connect to your server automatically become Licensed Clients. The Secure Server option is often easier to use than are Licensed Clients, and may be more cost effective. Licensed ClientsThe Licensed clients encrypt all communications with the server using the RC2 block encryption algorithm. Both login and application data are encrypted before being transmitted. All the GUI ScreenIO API calls are also encrypted, so that printing, file transfer, and other function data is never sent in clear-text. All communications between the client and the server are encrypted except for the initial key-exchange handshaking, when the server's public key is sent to the client (this is implicitly secure because of the way that public-key cryptography works). All subsequent communications are encrypted. Man-in-the-middle attacks are also detected. If multiple clients are attached to the server, every client uses a unique and randomly generated key for each connection, and furthermore, a new key is used for each application launched by the user. Licensed clients require a registration key. See our purchasing information. Other features of the Licensed Clients include:
Unlicensed ClientsNote: The unlicensed client is suitable for evaluation and for many low-security applications. You may decide that you can get by with unlicensed clients. Unlicensed clients are free, and may be downloaded at any time. The Un-Licensed client has the following limitations:
