You can determine the number of virtual devices to associate with the workstations that are connected to your system. This topic also provides security procedures for controlling or preventing access to Telnet.
Before configuring your Telnet server, there are some security and operational features consider. You need to know how many virtual devices you want Telnet to automatically configure or whether you want to create your own virtual devices. The number of virtual devices automatically configured affects the number of sign-on attempts allowed. An increased number of sign-on attempts increases the chances of an unauthorized user gaining access to your server. You might also want to consider other security measures, such as having the Telnet server detect lost connections.
