XSecurePro Version 8.3: X-Server with SSH.

Date: July 04, 2008

Labtam is pleased to announce a new software release of XSecurePro Version 8.3. This is the first major release for the 2008 year.

XSecurePro is our latest X-Server based software addition. Not only does it contain the key X-Server elements, it also provides Encryption Security using the SSH standard from PC to host machine. XSecurePro brings you maximum Security to a PC and a company LAN/WAN or Intranet/Internet.

Integrating the Microsoft Windows and X-Window System environments, XSecurePro is an inexpensive but powerful and effective way to transform a standard PC into a fully functional X-terminal.

Included in the package are the X-Window System, SSH, TCP/IP, FTP, TFTP, LPR, LPD, TELNET and NFS plus a whole lot more. Everything that you need to run all your remote Unix and X applications is included.

NOTES on this release (PLEASE READ):

1. The Beta3 MS Windows XP/2003/Vista x64 NFS-Client can be installed by running the self-extracting archive file, "nfsclx64.exe". This file and "nfsclx64.txt" can be found in the directory with the uncompressed package distributive.

2. The MS Windows 9x/ME/NT4/2K/2K3/XP/Vista NFS-Client can be installed by using the "Custom" installation mode only.

3. The Windows NT LPR printer driver is manually installed by running the self-extracting archive file, "lprd.exe". This file can be found in the directory with the uncompressed package distributive.

4. Use the "setup -wauto -s" command line (instead of "setup -auto") to start the "Silent Installation".

New Features on this release include:

1. Ftp:
- the "HideDrives" optional setting implemented to provide the disk drives' visibility. This allows you to reflect the Windows User Configuration -> Windows Components -> Windows Explorer Policy Settings. You can also provide your own drives' visibility;
- in the SFTP mode the ASCII/BINARY transfer mode switching was implemented (same as FTP mode). Important note. Since the added feature is non-standard for SFTP,please make sure you are aware that the initial state of transfer mode is "BINARY".
- the "NFS-Browser" mode was implemented to allow access to any remote NFS-Server's export without any NFS-Client installed on a local PC. It is the demo of the "NFS-Client SDK" usage. The "trNFSbr.cpr" file may be pointed in the "CPR file" input field to enable the full tracing.

2. NFS-Server:
- the "-RunOnTaskbar" did not allow the "Settings" item of the Taskbar menu (and the "Exports" button was passivated);
- to avoid the error message at shutdown of the PC with the NFS-Server running, the "GracefulExit=0" manual setting was implemented;
- the Unicode/UTF8 mode was implemented;
- the "Use UTF8 Name Format" setting is available in the "NFS-Server Settings";
- the "umask=<code>" optional setting was implemented to provide the understandable control of the files permissions. The default value is the traditional umask=0022.
The "FL_MITXELENA=1" setting is obsolete as subset of umask.
- the 8.3 filename is used in non-Unicode mode for files with non-ANSI long filenames.
- the "Exports" tab (the "Settings" item of Taskbar menu) is available now if the NFS-Server is started with "-RunOnTaskbar" option.

3. NFS-Client for MS Windows NT4/2K/2K3/XP/Vista:
- the UNC access has been significantly improved. A user can directly access remote NFS servers without the necessity to navigate via "explorer. This feature is available under WinXP/SP2, Win2003/SP1 and Vista;
- the empty "net use server:export" command line is now allowed to allow UNC access to NFS-Servers;
- the Unicode/UTF8 mode was implemented. The mounting exports must still be in ANSI only;
- the "NFS Settings -> Permissions -> Remember ROFS (Read Only File System)Reply" setting was implemented to block the Write(), MKDIR(), CreateFile(), Rename(), SetFileAttributes() operation on the NFS Server and return the STATUS_ACCESS_DENIED.
- NFS-Client can be installed now under MS Windows Server 2003 R2.
- the "super-silent" installation was implemented to provide the mode of "invisible" installation of the NFS-Client as the part of a foreign package;
- The NFS-Client now supports the "CheckDirList" request of the NFS-Client mini-DDK. It provides "pseudo" re-mapping(re-mount) actions for UNC-way access of "bad" remote NFS-Servers which can unpredictably restart sometimes. The checknfs.exe utility is the sample implementation of this (see the checknfs.txt for details).
- Processed the "sophisticated rename/delete MS Windows file operation" when long- and short- filenames are used very specifically during the first 15 seconds. (see MSDN Library "File Name Aliases" article). This is for the "Aditor" text editor;
- The "NFS Settings -> Name Converting -> Remember Long Name Alias" setting was implemented to provide a "sophisticated rename/delete MS Windows file operation" mode;
- The Authentication(PCNFSd and/or LDAP) usage are much more flexible now. Four new settings are now implemented :


- "NFS Settings -> Authentication -> Ask Authentication for each connecting attempt"
- "NFS Settings -> Authentication -> Use NFS Authentication during MS Windows Login"
- "NFS Settings -> Authentication -> Use MS Login Name/Password for NFS Authentication"
- In "NFS Client Authentication" Dialogbox has added the "Anonymous" button to set UID=-2 and GID=-2 for Unix Authentication

- The LDAP Authentication was implemented to access the LDAP Active Directory Servers of Windows 2003 R2 Standart Edition and/or Enterprise Edition. The mentioned Standard and Enterprise Editions have different schemes and require the additional tuning of the NFS-Client(see ldaptest.txt for details);
- The "NFS Settings -> Authentication -> Use LDAP v3 Server" setting was implemented to allow LDAP usage for Unix NFS Authentication;
- The "Permissions" tab is divided to "Authentication" and "Permissions";
- The "NFS Settings -> Permissions -> Use NULL Secure DACL" setting was implemented to set NULL DACL as parameter in any file operations.
- The "NFS Settings -> Name Converting -> Use this symbol as prefix for reaserved Windows names" setting is implemented to mark the reserved names as AUX, CON, NUL, and etc. By defauld is "^".
- The "NFS Settings -> Advanced -> NFS3 write synchronization mode" setting was implemented to set Asynchronous or Synchronous NFS-3 write mode. This has critical influence on the writing performance.

4. XServer:
- under Vista, with the "DesktopComposition" mode was enabled, the resizing/moving of windows in "Multiple" mode was very slow;
- the "TerminateOnSuspend=1" mode was implemented to provide a graceful termination of X-Clients on suspend of PC's;
- the XServer will be able to keep up to 126 X-Clients;
- the Animated Cursors are available now in "enabled RENDER" mode; The sofisticated scaling, cuttings and ARGB processing are provided.
- the "DisableRENDERAnimCursor=1" mode was implemented to provide the standard arrow instead of the true client cursor. This was done to accelerate and to prevent some ugly cursors of some X-Clients;
- the "-hwndParent <parentHWND>" option was implemented to allow to run the XServer/Single as subwindow of another Windows window. This is for the implementation of the "embedded XServer" ActiveX mode (see the xsrv_ax.txt for details);
- the Reply time limit of reading fonts from a FontServer are controlled now to avoid the delays for huge fonts (say, ISO10646 fonts)

5. XStartup:
- the "Disconnect" button was implemented for RLogin/RExec/RSH modes to process the possible infinite (with disabled "Exit after timeout of" setting) timeout carefully;
- the "LogFile" settings is available for RLogin

6. NFS-Client SDK:
- this all-sufficient Software Development Kit (SDK) can be run from your programs to provide access to exported resources of the NFS-Servers. Its application program interface (API) is similar to the standard one of MS I/O "File Management Functions" API. Full NFS-protocol access is provided without the necessity of using any other software (that can be installed on your PC and usually named as "NFS-Client for MS Windows").

7. Ftp/SFTP and Telnet/SSH:
- the higher priority of IPv4 (compare with IPv6) usage was introduced to avoid possible connection problems on some systems.

8. Telnet and Telnet/SSH:
- some terminals ("vt100","vt52"..) were not colored originally. The deviation from the strong emulation was implemented to allow to use colors for such as terminal types.

The following bugs have been fixed:

1. Ftp/SFTP:
- may crash after some sequental Connect-Disconnect... actions;
- some minor bugs were fixed;

2. Telnet and Telnet/SSH:
- the "Colors" attribute of the "VT240" terminal type (in the "terminfo.ini" file) incorrectly has the "3" value. It was changed to the correct "Colors=16";
- the initialization of the terminal window is more correct now;
- some bugs during the loading, viewing and edition of profiles were fixed;
- the "Log All session output" provides now the same with the "Log Prontable output only" Logging mode (wrongly did nothing, what is unexpected).

3. NFS-Server and NFS-Server as NT Service:
- NFS-Server may crash sometimes after "FileWrite" operation if the tracing mode is enabled;
- a little memory leaking was fixed. This problem might be visible after 1..2 weeks of the NFS-Server application running;
- NFS-Server returned sometimes the incorrect EXECUTE attribute in the ACCESS NFS-protocol reply. As result, some NFS-Clients failed to start the executable file on Unix side;
- the "rename" NFS-protocol request was answered with incorrect data. In most NFS-Clients the reply of the "rename" was ignored, but Fedora's one uses it. As result, the rename operation (e.g., "mv testfile1 t1" command) leaded to the "Stale Handler" on "ls" execution;
- the NFS-Server might crash if the "enable logging (to NFSLOG.TXT)" setting enabled;
- the crash took place if NFS-Client sent the wrong/incorrect file handle.

4. NFS-Client for MS Windows NT4/2K/2K3/XP/Vista:
- NFS-Client may fail to connect to servers if several network cards are used;
- the delay of reply on the "FileWrite" operation could lead to a crash of the system - BSOD("Blue Screen" error);
- NFSDRIVE and NFSALIAS crashed if the NFS-Server's export list contained item(s) with non-ASCII symbols;
- the space(blanc) symbols are allowed now in the mounting export path as well as in Windows Alias name;
- incorrect error message took place as result of changing of Unix Attributes via MS Explorer.

5. XServer:
- under Vista, with the "DesktopComposition" mode enabled, the drawing of "Rubber Rectangular"(e.g., "Edit"->"Copy Rectangular") resizing or moving of X-Client windows are very slow and dirtied the screen; (the "DesktopComposition" mode usually available in the AERO mode);
- fixed the error if the "KEYnn=MAC_macrofile.." item is used in a ".kmf" keyboard mapping file;
- the "ILikeXWinPro52=1" manual setting allows to provide the only "PseudoColor" visual with "888" colors weight instead of the default "666". This mode of the XServer (in 8-bits mode) is useful for some old CAD/CAE systems.
- reanimated the possibility to use the usual Windows "hosts" file as HostAccess list (when host access check is enabled).
- the unexpected "...-0-..." fonts are returned in answer xlsfonts when the fonts scaling is disabled. As result, some texts on screen (in this mode) may be unreadable.

6. XStartup:
- In rlogin mode the XStartup sends two end-line symbols (CR and LF) instead of the correct one (CR). This unexpected carriage-return symbol might lead to incorrect action of the "read" operation on the remote side.

7. XSettings:
- the "Default" button of the "Startup" tab did some incorrect settings as default.
