MyLogin

When terminals were replaced by PCs running terminal emulators such as comForte’s Win6530 or CAIL, users gained more than one access path (window) into the Tandem system from the same PC at a time. To establish a session, the emulator sends a request to TELNET, which replies with a list of configured services.

For the interactive Tandem user, TACL is the resource of choice. When TACL is started it is logged off and has to be activated through a logon: the user presents his system-known ID and the corresponding password. Logging on to one window is no big deal — but when several windows have to be started (developers and operations people love a bunch of active ones), the repeated logon procedure becomes tedious, especially several times a day.

Some emulators allow scripting the logon, but that requires hard-coding the password somewhere — insecure, and troublesome whenever the password changes.

The idea

Why doesn’t the Tandem system recognize that a user is coming from an environment (IP address, PC) from which they already logged on seconds ago, and use that to log them on automatically to subsequent windows? MyLogin forces the system to start the resource in newly opened windows already logged on, when:

• there is an already logged-on resource running on the same IP address, and
• the start is done within a given time frame after the last successful real authentication

In this case, no password has to be coded anywhere, and the end user gets easy AND secure access to multiple Win6530 emulator windows. MyLogin from GreenHouse performs exactly this.

Management

Manage MyLogin with the browser based management system iWAMS, the integrated Web Administration Management Suite, which allows central management of GreenHouse products within an EXPAND network.
