Click on General Settings under Pragma TelnetServer Manager dialog to configure general features that apply to all telnet sessions.
Maximum Connections
Configure the maximum # of connections that TelnetServer will accept at one time. This change will not take affect until all sessions have been disconnected.
NOTE: This setting only applies to the Unlimited-Connection Version of TelnetServer; changing this value will not have an effect on the 2-Connection or Demo versions of TelnetServer.
Perform Network Drive Cleanup (Windows 2000 ONLY)
Check this box to have Pragma TelnetServer delete all drives mapped during a telnet session.
TelnetServer will by default disconnect any network drives that were created during the telnet session. For example, suppose a user connects to the server and issues the following NET USE command:
NET USE X: \\SERVER\SHARE
This drive letter (X:) will be available to the telnet user in his session, and also to anyone else connected to the server. When the user exits his session, TelnetServer will disconnect drive X:, since it was created in the telnet session. Other network drives will not be affected.
In some situations, an administrator may want to remotely NET USE a drive from a telnet session, but then have that drive remain available for other users when he exits his session. This may be necessary for systems using NetWare connections. If all NetWare drive mappings are unmapped after a telnet session, change this option.
TIP: Mapped drives for multiple users is not supported by Windows. Some inconsistencies may appear for users. Drives may be listed as unavailable or not listed at all, even though a user can access it. Some drives may be listed as available, even though a user cannot access it. This is an issue with Windows.
Maximum Login Attempts
Configure the maximum number of failed logins before a user is disconnected from the server. The user is not locked out of the server, so they may try again immediately.
Display Authenticating Message
Check this box to display the authenticating message during logon.
Display Terminal Type Message
Check this box to display the terminal type that is set during logon.
Server to Client Heartbeat in seconds
Send a signal package to the client to check for an open connection. A setting in the box will prevent the server from staying open after a client has disconnected abnormally. For example, a power failure on the client side. The server sends a request for terminal type sub negotiation as a heartbeat. Most platforms will reply to this request. A low value will result in higher traffic due to the signal. A higher value will result in sessions remaining open for a longer period after the disconnection.
No heartbeat will be sent if the box is empty or contains a zero ( 0 ).
The session might close earlier than the configured amount of time, due to another error caused by the disconnection. This is beneficial since the telnet session has been orphaned and is unusable.
TIP: If a server heartbeat is active and a client disconnects at two times the server heartbeat value, turn off server heartbeat to see if the session remains open. If it does, the client does not support the mid-session negotiation.
User Authentication
Basic (Clear Text) and Secure Logon
If this option is enabled, TelnetServer will accept both encrypted and clear text logons from telnet clients. If the telnet client is configured to use encrypted logon, TelnetServer will encrypt all logon information. If the telnet client does not support encrypted logon, TelnetServer will accept the logon information in clear text.
Only Allow Secure Logon, DO NOT ALLOW CLEAR TEXT
If this option is enabled, TelnetServer will only allow encrypted logons to occur. If a telnet client which does not support encrypted logon attempts to connect to TelnetServer, TelnetServer will not allow them to make a connection. The client will be presented with a message indicating that only secure logons are permitted.
Do not use this option in conjunction with the /E command line parameter for telnetd.exe. These options conflict and the clients will not be able to connect. The /E option already specifies only encrypted sessions, which includes logon.
Allow NTLM Authentication
NTLM is an authentication protocol used in various Microsoft network protocol implementations. NTLM is used throughout Microsoft's systems as an integrated single sign-on mechanism.
To enable NTLM authentication for Pragma TelnetServer, click on the Allow NTLM checkbox. Then connect to Pragma TelnetServer using any client, which supports NTLM. All Pragma clients support NTLM. The interactive user information will be set as the remote user context, using Windows certificate based authentication, will connect you. The User is not prompted for username or password. NTLM authentication cannot be used to logon as a user other than the client interactive user.
