Restrict Access Based on the Telnet Encryption

This feature allows connections only from the encrypted Georgia SoftWorks Telnet Client. This is another level of security that the system administrator can configure. Many times the system administrator wants to ensure that ALL connections to the GSW UTS are encrypted.

Note: This feature is only relevant for Telnet. By the nature of SSH2, all connections are encrypted

The variable RequireEncryptedSession is a registry key value. This Registry key enables or disables the ability to restrict encrypted only sessions. If it is disabled then only users using the Georgia SoftWorks Telnet client are allowed to connect. The key is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\GS_Tnet\Parameters\RequireEnctyptedSession

The default value is 0(That is disabled). The value 1 only allows encrypted sessions to connect. The value 0 allows both encrypted and un-encrypted sessions to connect to the Georgia SoftWorks Telnet client. This value must be left set to 0 (the default) if running the GSW SSH2 Server

Note: Use of this feature overrides user settings in the logon script and force clients to use encrypted session data stream.

Please make sure the registry parameter:

EnableEncryption

is set to 1 and that the Georgia SoftWorks Telnet Client uses the /c command-line option.

After you complete your settings you will notice the following:

1. a.) 3rd party clients will report disconnected session before the user even tries to type his logon name.
2. b.) GS clients who do not have /c option will fail to connect.
