SUMMARY
********************************************************************** Microsoft Windows NT Services for UNIX Release Notes

The following tips will be helpful as you install and use the Microsoft Windows NT Services for UNIX Add-On Pack.

=
========================================================= Setup

=
========================================================= You cannot upgrade from a beta version of Microsoft Windows NT Services for UNIX Add-On Pack. If you have installed a beta version, you must reinstall Windows NT 4.0 using the New Installation setup option and then reinstall Service Pack 3 before you install Microsoft Windows NT Services for UNIX Add-On Pack.

If you already have any third-party version of Telnet server installed on your computer, you must remove it before you install the version of Telnet server provided with Microsoft Windows NT Services for UNIX Add-On Pack.

Upgrades from Intergraph DiskAccess and DiskShare 3.0 are not supported.

Microsoft Windows NT Services for UNIX Add-On Pack has not been tested on Windows NT 4.0 Terminal Server or Windows NT 4.0 Enterprise Edition. Use on these operating systems is not supported.

=
========================================================= Silent Installation (Setup /s)

=
========================================================= Silent installation does not require the user to enter any information or make any choices during the installation process.

To perform silent installation

1. Copy the folder that contains the files for your type of processor (i386 or Alpha) from the CD to your computer.

2. Open scsetup.inf in a text editor and find the following line of code (the first line following the comments): Windows NT Services for UNIX,\SFU,

3. Add the PID to the end of the line. For example, after editing scsetup.inf the first line would look something like the: Windows NT Services for UNIX,\SFU,X2Y23-W2B2A-XYZRA-ZEBRA-LAST5.

4. Save scsetup.inf.

5. In the Start/Run dialog box, type the path to the directory that contains the installation files followed by setup /s.

=
========================================================= Installing the Microsoft Windows NT Services for UNIX Add-On Pack with FX!32

=
========================================================= Services for UNIX cannot be installed while FX!32 is running. To install Services for UNIX, first turn off FX!32. Following the reboot at the end of the installation process, restart FX!32.

FX!32 also needs to be turned off before Services for UNIX can be uninstalled.

=
========================================================= Uninstall Procedure

=
========================================================= You can uninstall Microsoft Windows NT Services for UNIX Add-On Pack by using the uninstall feature provided with the product. You can gain access to this feature by selecting either: *Uninstall under Common in the Services for UNIX Program Group *Services for UNIX under Add/Remove Programs in the Control Panel

=
========================================================= Installing MKS Demoware

=
========================================================= You can manually install the MKS Demoware by running install.bat from the 3rdparty\mks directory on the Microsoft Windows NT Services for UNIX Add-On Pack CD.

Mortice Kern Systems (MKS) has provided this trial product as a courtesy to Services for Unix customers. Microsoft does not provide support for the MKS demoware product.

=
========================================================= Change the Default Shell for Telnet

=
========================================================= To change the default shell for the Telnet Server service

1. Create a batch file that contains the full path to the shell executable you want to use. For example, a batch file for sh.exe, Shell.bat, would contain the single line C:\SFU\Shell\sh.exe. 2. Using the tlntadmn tool, set the DefaultShell registry setting to the full path to the batch file. For the example, the DefaultShell registry entry would contain C:\SFU\Shell\Shell.bat.

=
========================================================= Configuring UNIX Computer for Password Synchronization

=
========================================================= A sample ssod.config file is included with the product. It is located in the \common\unix directory on the distribution CD. Please refer to this file when configuring a UNIX computer for password synchronization.

The ssod.config file contains the shared secret, which is a plain-text string used to encrypt the username/password sent from Windows NT to UNIX. File/directory permissions for this file should be set so that only privileged users can read it. We suggest file ownership by root, with read-only access by root such as -r, or 0400.

The ssod daemon should also be given file permissions so that only privileged users can access it. We suggest file ownership by root, permissions of -rwx--, or 0700.

For information about UNIX platforms supported by Password Synchronization, go to www.microsoft.com/unix/sfu.

=
========================================================= Setting NFS Share Permissions

=
========================================================= If the NFS Share Permissions are set to read/write or read only and if Allow Anonymous UID has been turned off, root cannot mount. If the NFS Share Permissions are set to root, root can mount.

=
========================================================= Using ln.exe

=
========================================================= Ln.exe creates hard links to files. Hard links are pointers to files and are indistinguishable from the original directory entry. Any changes to a file are effective regardless of the name used to refer to the file (the original name or the link name). Hard links cannot span file systems or drives and are not currently supported within NFS mounts or from NTFS to the mount.

Ln.exe does not create links over NFS. Using Ln.exe, you can create links on UNIX clients that reference a Server for NFS, but you cannot use Client for NFS to create links on a UNIX computer. If you create a link on the UNIX host, Client for NFS uses the link correctly.

Symbolic links are indirect pointers that contain the name of the file to which they are linked. Symbolic links can span file systems and may refer to directories. Symbolic links are not implemented in this version of Ln.exe.

=
========================================================= Viewing Help for UNIX Shell Commands

=
========================================================= To view help for shell commands, type -? after the command.

=
========================================================= Viewing Shared Directories

=
========================================================= To view shared directories on a computer running Server for NFS, in Start/Run, type net view /network:nfs \\server.

=
========================================================= PCNFSD Printing Capability

=
========================================================= The PCNFSD printing capability is not supported in version 1.0 of Services for Unix, and it is scheduled to be removed from the product in version 2.0. However, client authentication via PCNFSD is fully supported in version 1.0.

=
========================================================= Refreshing Status of NFS Mounted Share in Windows NT Explorer

=
========================================================= In Windows NT Explorer, the status of an NFS mounted share cannot be refreshed if the share was mounted using a UNC path in the Start\Run dialogue. For example, if you use Start\Run to mount \\Servername\NFSsharepath and then select View\Refresh in Windows NT Explorer window, the error message, "\\Server is not accessible. The network name cannot be found" appears.

The suggested workaround is to map the NFS UNC path to a drive letter and then refresh it's display. Consult the Microsoft Knowledge Base for current information about this problem.

=
========================================================= Setting Telnet Server to use Only NTLM Authentication

=
========================================================= The Telnet Server can be set to use only NTLM authentication. This will provide increased security during Telnet authentication, and it will prevent telnet user credentials from being passed as clear text on your network. With this setting, only Telnet clients that support NTLM authentication will be able to connect to the Telnet server. After you make this change, you will be able to Telnet only by using NTLM (NT Domain) credentials. You won't have to enter the username/password; logon will happen automatically.

To set the Telnet Server to use only NTLM authentication

1. In Start/Run, type tlntadmn and click OK.

2. Choose Display/change registry settings.

3. Choose NTLM.

4. Change the NTLM value to 2.

5. Restart the Telnet Server.

=
========================================================= Disabling NFS Version 3 Support to Avoid Loss of Files

=
========================================================= If you use Microsoft Windows NT Services for UNIX with an operating system that uses NFS Version 2 (such as IBM OS, MVS, OS/2, or AIX), files can be deleted if NFS Version 3 support is turned on on the Server for NFS.

To disable NFS Version 3 support, open the Server for NFS Configuration dialog box, click the Server Options tab, and clear the checkmark in the NFS Version 3 Support checkbox. Click OK to close the dialog box.
