This feature allows connections only from the Georgia SoftWorks SSH2/Telnet Client. This is another level of security that the system administrator can configure. Many times the system administrator will not want users using any generic client to connect to his or her system.
The variable EnableRFC854Clients is a registry key value. This Registry key enables or disables the ability to restrict connection from 3rd party clients. If it is disabled then only users using the Georgia SoftWorks SSH2/Telnet client are allowed to connect. The key is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\GS_Tnet\Parameters\EnableRFC854Clients
The default value is 1 (That is enabled). The value 1 enables the ability for connection from all telnet/SSH2 clients. The value 0 restricts connection to the Georgia SoftWorks Telnet/SSH2 client.
After you change the value for EnableRFC854Clients, it will take effect for all new connections
