Release Date: 04/18/2012
Revision #: 1715

Enhancements:

- telmc column formatting improved to work in both 80 column and larger 132 column consoles. Shows connected state in a column labeled "S" meaning state with one character: C means connected. R means awaiting reconnect.
- Beeping is eliminated in the server side. Rather Control-G character is captured and sent to the client side for the client to beep. System beep call was already handled properly in previous release to beep in the client and not the server, so continues to work properly.
- View Session new advanced architecture now allows TelnetSSL and SSH sessions to be viewed as well as Telnet sessions.
- Install adds Windows firewall enabling entries so that Pragma Inetd and Cmdserver can open needed TCP ports for connections. Before this, one had to manually add the entries in the Windows Firewall after install. For Non Windows firewall, one still has to do it manually.

Fixes:

- Session count is reduced properly before a session goes to waiting reconnect state. This allows a new session to come in and reconnect. Limiting session to 1 also would work for reconnect which was failing before this fix.
- Servers with Pragma telnet server installed were sometime rebooting itself spontaneously as CcmdServer.exe process terminated the csrss.exe process during shell process cleanup.

Release Date: 01/18/2012
Revision #: 1584

Enhancements:

Release Date 11/29/2010
Revision #: 1055

Enhancements:

-More efficient code is now used to verify a user is in a Group that does property queries of AD Object instead of specific AD User and AD Group calls. Checks for user validity by comparing user SIDs instead of username, domain pair, etc. which fails on Win2008 domain controller
- Enhanced for 1000 or more sessions right out-of-the box in present Gen2 code architecture.

Fixes:

- Some small memory allocation is now freed correctly for server to not accumulate them

Release Date 06/28/2010

- "Compatible with Windows 7" logo status achieved.
- Returned call to TerminateJobObject to our TerminateCommandShell so that MonitorChildProcesses is checked, graceful termination is available, and Recording of terminated events occurs.

- Modified logging for server process to create unique file name based off PID and time and pass as argument to CmdServer

Fixes:

- Running it in Win 2000 server does not need turning on "Replace a Process Level Token" user rights change
- default value for ThreadDriveMap changed to off, so that drives can be available for non-interactive sessions
- Default value for CustomAppSupport now set to yes.
- Fix for garbage characters showing up on screen in Advanced Console
- Initial screen sent when viewing a session
- PragmaMgrC.exe invokes registry editor correctly (regedtc.exe in place of re.exe)

Release Date 07/15/09
Revision # 332

Enhancements:

- New Pragma Gen2 architecture for higher speed, reliability and enterprise deployment readiness.
- SSL support added to Telnet server. Pragma uses Microsoft Crypto (FIPS and US Govt certified) to build our SSL unlike the competitors who use open source openssl
- Advance console and Shell support greatly improved by reducing APIs needed to be redirected - Reconnection of dropped sessions is now made more robust with Gen 2 architecture. Useful for Handhelds.
- Handheld configuration settings consolidated in a separate page on Local Server Configuration program for ease of setting up Handheld connectivity options
- Server to Client heartbeat setting moved to user level configuration to allow per user customization if needed. - Server has added smart logic to distinguish between explicit disconnect issued by user versus disconnect due to network connection drop. The former will not cause "Reconnect" mode to be entered but the latter will. Handhelds reconnection support needs this smart disconnection difference detection for real life use
- Improved Group Membership algorithm for group based access restriction control - Customer Application has clean documented way to send custom code for beep or special functions. Pragma telnetd and sshd can work with the same custom code written by customers
- User drive letter mapping improvements to get logon prompts quickly by launching an extra thread that maps user drives in the background; this thread exits when done. ThreadDriveMap can be set to "no" to avoid this asynchronous drive mapping for scripts who may need drive letters at the launch
- Windows PowerShell is now fully supported and can be set as the default shell
- Supports new Windows Server 2008 R2 and Windows 7
- All languages supported by Windows are now supported by sshd server and clients. UTF-8 (65001) is a good page to choose. Users can choose any CodePage and Fonts that support their national language.

Fixes:

- Group access not detected correctly
- Client disconnects at any time will not tie up telnet server
- Fix for orphan sessions not cleaning up requiring reboot of server
- If "PATH" in user level was set, it would override "PATH" in system level. Now User level PATH is appended after system's PATH.

Clients/Tools:
- telnetc supports TelnetSSL protocol. telnetc /s option is used to invoke SSL.

FortressCL
- control-c and control-break is now passed to server enabling application termination/exit.
- TelnetSSL protocol is now supported.

Known Issues:

- In stream mode server, history up/down arrow keys do not work to retrieve commands (also in Build1)
