Access Network Drives Through the Windows File Manager

The Windows File Manager is the tool you use to connect and disconnect network drives, or to change the properties of a network file or directory.

You access these functions from two File Manager menus, the Disk menu and the Network menu. From the Disk menu you can connect a network drive, disconnect a network drive, or select a network drive. The Network menu provides choices that let you view long file names (more than the DOS 8-by-3 character limit), change the properties of network files or directories, and convert files between DOS and UNIX formats.

Use the functions in File Manager to:

Choosing a Network to Access

Use the Pick a Network dialog box to choose a network to connect to a file or print server.  If you set up PC-NFS to share the network card driver of an existing network, this dialog box opens each time you connect a drive.

To choose a network, click on the desired network button.  The selected network is loaded and you can use that network to connect to a drive or browse its resources.

Once a drive is connected, you cannot change the network without disconnecting and reconnecting the drive.  You can connect to only one network at a time.  For example, if you are running Novell NetWare and Digital PathWorks networks on your PC, you can connect Drive D to the NetWare network.  You must then disconnect Drive D before connecting another drive to the PathWorks network

Click on the check box to use the same network for subsequent network connections during the current windows session.  The Pick a Network dialog box will not open again during the current windows session.  So, you cannot choose a different network until you exit and restart windows.

Set Basic Drive Connection Options

You set default drive connection options in the NFS portion of PC-NFSpro Configuration. However, every time you connect a drive, the Drive Connection Options dialog box allows you to override the default settings for the drive that you are connecting. Once a drive is connected, you cannot change connection options without disconnecting and reconnecting the drive. Therefore, to override the default connection options, change connection options when connecting a drive. You can view drive connection options at any time.

There are two levels of drive connection options: Basic and Advanced. The Basic options are:

Connect Option	Provides the following drive access
Reconnect on Login by username	Reconnect the drive when you log in. However, if you disconnect the drive before you quit Windows or log out, the drive is not reconnected when you next log in.
Connect Drive Read Only	Do not allow modification of files on the drive.
Use File Locking/Sharing	Use only if the server has lock manager capability and if you are using applications that have file sharing and /or file locking.
Advanced Drive Connection Options are displayed if you choose the Advanced button.

Browse to view a list of file systems on a given server. Choose Previous to see a list of connections which you have made previously.

Browse a Network Server for Files and Applications

To connect to a drive, you need to know the name of the file server and the file system to which you want to connect. Browsing lets you identify this information. To browse:

1.	Start File Manager.

2.	Open the Disk menu and choose Connect Network Drive.

If you have set up PC-NFS to share an existing network card driver, the Pick a Network dialog opens.

3.	Click on the desired network to access.

The Network Drive Connections dialog opens.

3.	Choose Browse.

The Browse Network File Systems dialog opens.

4.	Open the Servers list box and select a server name. Alternatively, enter the name or IP address of a server in the Servers edit box.

5.	Choose Show Exports.

A list of available (exported) file systems that you can access on that server is displayed in the Exported File systems list box. Select a file system by double-clicking on it, or by selecting the file system and choosing Select. Selecting a file system causes the Network Connections dialog box to be redisplayed with the Network Path filled in.

6.	After the Network Connections dialog box is redisplayed, you may add additional path information.

Note: The initial browse list contains server names you entered during PC-NFSpro configuration. These names include: PCNFSD, DHCP, NIS, DNS, license, and gateway servers. Subsequently, when you type in a server name that PC-NFSpro is able to successfully browse for exported files, PC-NFSpro adds the name to the browse list. In addition, you can manually enter the name or IP address in the form of servername=[name or IP address] of any server you want to browse in the NFSD section of the BROWSE.INI file.


Set Advanced Drive Connection Options

You set default advanced drive connection options in the NFS portion of PC-NFSpro Configuration. However, every time you connect a drive, the Drive Connection Options dialog box opens, allowing you to choose the advanced button and change advanced drive connection option settings.

Advanced Drive Connection Options control additional reconnection options, data transfer options, privileges for files you create, and file name mapping for the files you access with the connection.

You can change the following advanced options at the time you create a drive connection:

Additional Reconnection Options

Data Transfer Options

File Creation Options

File Name Mapping Options


Additional Reconnection Options

You can choose to reconnect a particular drive not only when you log in, but when any other user logs in on your PC. To do this, select the check box labeled Reconnect this Drive on Login by Any User. If you select this option for a particular drive, note that not only you, but any other user who is logged in may disconnect the drive.

Another option is to require user authentication before a particular drive is connected. This option establishes the user's credentials for the specified drive, but does not log in the user again. To do this, select the check box labeled Prompt for User Login for this Connection.


Data Transfer Options

Change these only if you are familiar with the details of data transfer, or have been advised to do so by your system administrator.

Increasing Read Size improves performance, but some network adapter boards do not provide a large enough storage area (buffer) to handle the increased amount of incoming data. In addition, you may need to reduce Write Size if the server you connect to has limited buffering, if you are using a network adapter board with limited buffering, or if you connect over an error-prone link.

For optimum performance, always use a multiple of 1024 for the read and write sizes.

Data Transfer	Definition	Default/Notes
Read Size	The number of bytes in a data block read from a file in an NFS data transfer.	Default: 1024 bytes  Minimum: 1 byte  Maximum: 8192 bytes
Write Size	The number of bytes in a data block written to a file in an NFS data transfer.	Default: 8192 bytes Minimum: 1 byte  Maximum: 8192 bytes
Retries	Number of times to retry transmission before stopping.	Default: 4 times
Time-out	The time, in tenths of a second, before starting a retry.	Default: 7  Set to 0 to retry indefinitely. This is not recommended.


File Creation Options

Use the File Creation Options dialog to establish the permissions of files you create. When you create a file, its permissions are defined by your user ID. The changes you make to the default file permissions are retained until you reboot your machine, or change them.

Once you establish file permissions, connect a drive, and create a file, you can change the permissions of the file. Use the Change Permissions menu item in the File Manager Network menu or the Properties menu item in the File menu. See Properties for more information.

Select or deselect a check box to make a permission change.

Users	Explanation
Owner	Yourself
Group	Groups of which you are a member; for example, legal
Other	Everyone else
Permissions	Access Provided
Read	View or copy file.
Write	Modify, remove, or rename file.
Execute	Run file, such as program or shell script, or for directories, change directory.


File Name Mapping Options

File name mapping options enable you to view and work with files that do not conform to DOS file-name conventions. You set default file name mapping options in the NFS portion of PC-NFSpro configuration.

Use the file name mapping options in this table to override default file mapping for a specified drive.

Mapping Option	Meaning	Example
Map Names Using ^ (or other mapping character such as ~)	Turn on file name mapping, by selecting the check box.	The network file named .login is mapped to ^LOGI^XX because a leading period is illegal. If file name mapping is not turned on, the network file named .login would be invisible to a Windows application.
Default Names are Lowercase	File names with all lowercase letters are not mapped with the ^ (or other mapping) character.	If name mapping is turned on, the file named abc.def is not mapped, but the file named ABC.DEF is mapped to ABC^^^XX.DEF. If Default Names are Lowercase is not selected with a check mark, the uppercase file named ABC.DEF is not mapped, but the file named abc.def is mapped. If file name mapping is turned on, you can view files in File Manager by their original names. To do this, make sure the menu item Enable Long File Names is marked with a check in the Network menu of File Manager.
Ignore CD-ROM Extensions	The extra extension often used with CD-ROM or OS/2 files is ignored. The file name, if otherwise valid in DOS, is not mapped with the ^ (or other mapping) character.	The file named accounts;13 appears in a Windows application as accounts.
Ignore Case in Names	The server ignores case in names.	The file name Accounts is displayed whether or not mapping is turned on. If you are creating a network file from a Windows application, or Default Names are Lowercase is selected, the file is created on the server with a lowercase name (if the server preserves cases).


DOS File-Name Conventions

DOS file names cannot be more than eight characters long, with a three-character extension. In addition, a DOS file name cannot contain the following characters:

"  .  /  \  [  ]  : < >  +  =  ;  ,

PC-NFSpro file name mapping uses the first five characters of the original DOS file name in uppercase, followed by a caret (^) in the sixth character position. (The mapping character is configurable; caret is the default.) The seventh and eighth characters are random characters generated by the mapping to ensure that each name is unique. If any of the first five characters is not a permissible character, or does not exist, it is replaced by a caret.

Finally, any extension that conforms to DOS file-naming conventions is appended. If the extension is impermissible in DOS, PC-NFSpro software includes the extension in the mapping.


Disconnect a Network Drive

Disconnecting a drive breaks the connection between your PC and the server where the files you are accessing reside. To disconnect a network drive:

1.	Start File Manager.

The File Manager window opens.

2.	From the Disk menu, choose Disconnect Network Drive.

The Disconnect Network Drive dialog box opens.

3.	In the Network Drive list box, select the drive letter of the drive you want to disconnect.

Note: Be sure the drive is not being used by any applications.

4.	Choose OK.

The drive is disconnected and is removed from the Permanent Connections list.

Tip: You can also disconnect a network drive from the Network Drive Connections dialog by highlighting the drive letter and choosing Disconnect.

View the Properties of Network Files and Directories

If you own a file or directory, you can change its properties, including its ownership, the groups which can access it, and its access permissions. If you do not own a file, you can display its properties, but not change them.

Note:  Even when you own a file, you can only restrict permissions, not expand them. For example, if you create a file on a drive with Group Read permission enabled, you cannot later expand Group permissions on this file to Write and Execute. You can remove this file's Group Read permission, however.

To change a file's properties:

1.	Open File Manager and select a network file or directory.

2.	Open the Network menu and choose Change Options.

The Properties for the file or directory are displayed.

3.	To change the file's ownership, type the user ID of the new owner in the Owner edit box.

4.	To change the primary group that can access the file, type the group ID of the new group in the Group edit box.

5.	To reduce the File Permissions, deselect the appropriate check boxes.

Users	Explanation
Owner	Yourself
Group	Groups of which you are a member; for example, accounting
Other	Everyone else
Permissions	Access Provided
Read	View or copy file
Write	Modify, remove, or rename file
Execute	Run file, such as program or shell script

6.	Choose OK to confirm these changes. Alternatively, choose Cancel to discard the changes.

7.	To view additional information about a file, such as file size or date of last change, select a file and then select Properties from the File manager File menu.


View Long File Names

PC-NFSpro allows you to view file names that do not conform to DOS file name length limitations. To view long file names, you must enable file-name mapping so that PC-NFSpro recognizes non-DOS file names, and you must also enable File Manager's long file name option. In addition, certain limitations apply to long file name operations and use.

Warning: Using the combination of PC-NFSpro and Windows for Workgroups 3.11 with PC-NFSpro configured as a secondary network will not allow the display of long file names.

Tip: When using NFS-mounted drives, select File Manager's Options->Font menu item and select the check box labeled Lowercase to turn off automatic display of file names in lowercase letters.

To view long file names:

1.	Start File Manager.

The File Manager window opens.

2.	Open the File Manager Network menu and choose Enable Long File Names.

A dialog box opens prompting you to exit and restart File Manager.

3.	Exit and restart File Manager.

4.	Connect a network drive with the Advanced->File Name Handling->Map Names Using option enabled.

File names associated with the drive are displayed in long form.

Tip: You can use standard File Manager features with the long names, such as moving, copying, deleting, renaming, or running files or creating directories.

Long File Name Drag and Drop


Long File Name Limitations

Due to the way long file name support is implemented in the Windows File Manager program, certain limitations exist regarding the use of the PC-NFSpro Long File Names function.

These limitations are:

1.  Long file names are available for use only within File Manager. For example, you cannot drag and drop a long file name from File Manager to an external application such as Notepad.

2.  File Manager is case insensitive. As a result, uppercase names may be displayed as lower case. You can compensate for this by connecting drives with the Ignore Case option enabled, and /or by setting the File Manager display font to uppercase.

3.  You cannot execute a program if the program's name, or the name of any component in its path, is a long file name. (In this context, a long file name is any name that does not conform to the DOS 8-by-3 character convention.)


Long File Name Drag and Drop

In long file name drag and drop operations from a local drive to an NFS-mounted drive, Windows File Manager will map file names by default. In many circumstances, you may want to prevent this file name mapping. For example, if you plan to drag files from a local drive to an NFS-mounted drive and then back again, you will need to prevent name mapping in order to preserve the original file name (mapping characters occasionally change within file names).

You can prevent long file name mapping by using NFS Drag and Drop.

Tip: You can safely ignore the warnings File Manager issues about being unable to access created files.

To choose NFS drag and drop:

1.	Enable long file names.

2.	Open the File Manager Network menu and select Choose Drag and Drop Model.

The Choose Drag and Drop Model dialog box opens.

3.	Select the NFS Drag and Drop option, and choose OK.

4.	Close File Manager, and then restart it.

Drag and drop operations performed in File Manager will now avoid file name mapping.

Tip: Be sure to press the F5 key to refresh the File Manager display after a drag and drop operation.

Displaying Drive Connection Options

You can see what drive connection options are in effect for a specific drive.

To display a drive's connection options:

1.	Open the Network Drive Connections dialog box and select a current drive connection.

2.	Choose the Options button.

A display-only version of the Drive Connection Options dialog opens. Current connection option values for the drive are displayed next to each option item.

Tip: You cannot change connection options for a current drive connection. To change a drive's connection options, disconnect the drive and reconnect it, specifying new options.


Previous Drive Connections

The Previous Drive Connections list enables you to select a drive connection that you have previously used.

To select a previous drive connection:

1.	In the Network Drive Connections dialog box, choose the Previous button.

The Previous Printer Connections dialog box is displayed.

2.	Select a previous drive connection and choose Select.

The Network Drive Connections dialog is displayed and the Server Name and path name are filled in with your selection. You may modify this path.

3.	If you wish to remove previous connections that you are unlikely to use again, select the network path and choose Delete.

When you are done, choose Cancel to return to the Network Drive Connections dialog.


Troubleshooting Drive Problems

Here are some problems you might have on an NFS client when connecting to a network:

Problem	Possible Causes	Solution
Server not known.	Your computer cannot find an internet address for the NFS server  in its name service (for example, NIS, DNS, or hosts file.)	Use ping to make sure you can reach the server machine. Ask your network administrator for the correct internet address and host name for the NFS Server machine. Use the TCP/IP configuration dialog box to add the correct internet address for the NFS server to your name service.
Illegal path.	The directory does not exist on the server.	Try to mount the directory level above the directory you could not mount.  Then, browse to see if the directory exists or is spelled differently.
	You typed the directory name incorrectly.	Mount again, using the correct spelling.
File not in export list.	The server is not exporting the directory.	On the server, use Configure NFS Server to export the directory.
Access denied.	The server does not export the directory to the client machine.	On the server, use Configure NFS Server to change the access list for the exported directory. See Restricting Access to Certain Hosts and Revoking Hosts Access Privilege
Read-only file system.	The server exports the directory with readonly permissions.	On the server, click on Edit Access List from the NFS Configuration dialog box.   Make sure the Read Only check box is not checked to allow full read, write, and execute permission to the exported directory.
Stale file handle.	Files on the server have changed, since the client mounted the file system.	Close the NFS server program and double click on its icon to restart the program.
Can mount a remote file system, but cannot mount a remote printer.	The printer whose server you are mounting might not be running pcnfsd.	Verify that the server is running pcnfsd by using the command: rpcinfo -u servername 150001 You should receive the response: proc 150001 is ready and waiting.   Make sure that the spool directory is exported by the server.  The default is /usr/spool/pcnfs.
Can mount a directory, but cannot create or edit a file in the directory.	Portmapper daemon not running on server.	On server, start the Network Event Log and set the error level to Debug. Enable RPC logging by opening the Port Map icons system menu and choosing Log RPC Activity. On the client, use the rpcinfo command to make sure that the Port Map daemon is running and registered correctly on the client and server: rpcinfo -u portmap rpcinfo -u servername portmap
RPC: program version mismatch.	The client and server are not running the same version of an RPC service, such as, Port Map or NFS.	On the server, enable Network Event Logging at the Debug error level. On the client, use the rpcinfo -p command  to check the version of RPC services running on the client and server: rpcinfo -p rpcinfo -p servername


Network Coexistence

PC-NFSpro can coexist with another software network by sharing its network card driver  Sharing the card driver allows you to run three networks at the same time.

Windows lets you configure a maximum of two networks (Windows for Workgroups and one other).  Configuring PC-NFSpro to share one of the existing network card drivers, you can access the resources of all three networks.


Network Card

A network interface card (NIC) is an adapter installed in a computer that provides the connection point to a network.  Each card is designed for a specific type of network (such as Ethernet and Token Ring).


Network Card Driver

Software that provides an interface between  a network interface card (NIC) and the operating system in your PC.

The network card driver formats data from a particular network protocol (such as, industry-standard TCP/IP and Novell's IPX/SPX) for a particular network topology (Cabling and standard for sending data across the cable).

Troubleshoot Printing Problems


Three Steps to Printing

There are three steps to printing with the PC-NFSpro program:

1. Choose a print protocol

2. Select a printer

3. Set printing options (this step is optional)

The PC-NFSpro software provides two print protocols:

LPR - This protocol is available on Berkeley UNIX systems. You can use it if the print server you select is running a Berkeley Standard Distribution (BSD) compatible line printer daemon. You need not connect to a printer to print a job using the LPR protocol (unless you are printing directly from an application). You can use LPR QuickPrint to send a job to any LPR printer.

PCNFSD - You can use this protocol if the print server you select is running the pcnfsd program. This program is available on many systems in addition to UNIX systems. You must connect to a printer to print a job on it using the PCNFSD protocol.

For more information about which protocol to choose if both are available to you, see Choosing a Print Protocol

You can set up multiple printer connections, and you can connect to LPR and PCNFSD printers simultaneously. Ask your system administrator which protocol to use if you do not know the protocols running on the print servers you select.

Note: To ensure error-free printing with all your applications, be sure that the Use Print Manager check box is enabled in the Windows Control Panel, Printers, dialog box.

To connect to a network printer, you must identify the printer (by name) and also the print server that oversees the printer's operation. If you are printing with the PCNFSD protocol, use the PC-NFSpro printer browser to examine your network for the names of printers and print servers.

You can set basic and advanced print options. Basic options allow you to reconnect to printers automatically each time you start the Windows program, and to specify the print protocol used in each individual connection. Advanced options offer an additional reconnection choice, and for the PCNFSD protocol, allow you to specify a spool drive and to determine data transfer options.

You can print directly to a network printer from an application if you associate a device name (for example LPT1:) with a network printer. When you want to print to the network printer, you use the device name.

Note: If the print server supports the LPR protocol and you do not need to print directly from an application, use the LPR QuickPrint program to send a job directly to the printer. See LPR QuickPrint help for more information.

Set Printer Connection Options


Choose a Print Protocol

You choose a print protocol when you configure the PC-NFSpro program. This selection becomes the default print protocol. You can also specify a protocol each time you connect to a printer. This protocol selection overrides the default protocol setting for the particular printer.

Here are some guidelines about whether to use the PCNFSD or LPR protocols if both are available to you.

1.  If you intend to browse for printers, use the PCNFSD protocol. The LPR protocol does not support browsing.

2.  If viewing the name of a print job in the Print Manager is important to you, use the LPR protocol. This protocol displays the name of the print job in a way that you can understand it, but the PCNFSD protocol will not.

3.  If you use the PCNFSD protocol, you will need to use a drive for spooling, but you will not if you use the LPR protocol.

4.  The LPR protocol is usually more efficient because the PCNFSD protocol has more overhead associated with its use.

To select the default print protocol:

1.	Start the Configuration program.

The Configuration - Default dialog opens.

2.	Choose Printing.

The Print Client dialog opens.

3.	Select a protocol by clicking on the Use LPR Protocol or the Use PCNFSD Protocol option button.

The selected protocol's option button is filled in.

4.	Choose OK.

The selected protocol becomes the default protocol. The Configuration Default dialog returns.

5.	 Choose Save.

Your default print protocol selection is saved.

To override the default protocol when you connect a printer, see Set Basic Printer Connection Options

You can choose to reconnect a particular printer not only when you log in, but when any other user logs in on your PC. To do this, select the check box Reconnect this Printer on Login by Any User. If you select this option for a particular printer, note that any user can disconnect this printer.

Spool Drive (PCNFSD protocol only)

When you send a job to a printer, PC-NFSpro software places the job in a holding area on the print server called a spool drive. This spool drive is connected when you connect a printer. You can reserve a drive letter exclusively for spool drive use, or you can assign any available drive letter at the time of printing.

To reserve a drive letter exclusively for spool drive use, select the option button Use Drive and select an available drive letter from the Spool Drive list box.

To assign an available drive at the time of printing, select the option button Assign Drives Dynamically before Printing.

Data Transfer (PCNFSD protocol only)

Change these values only if you are familiar with the details of data transfer, or have been advised to change these by your system administrator.

Data Transfer Option	Description	Notes
Write Size	The number of bytes in a data block sent to the printer in an NFS data transfer.	Default: 8192 bytes Minimum: 1 byte Maximum: 8192 bytes You may need to reduce the write size if the server has limited network buffering, if you are using a board with limited buffering, or if you are using an error-prone link.
Number of Retries	Number of times to retry transmission before stopping.	Default: 4 Range 1 to 9999 Set to 0 to retry indefinitely. This is not recommended.
Time-out	The initial time, in tenths of seconds, before starting a retry.	Default : 7  Minimum: 1 Maximum: 300


Disconnect From a Network Printer

Disconnecting a printer breaks the connection between your PC and the printer.

Note: Do not disconnect a printer on which you are actively printing. If you have already spooled jobs to that printer, and the jobs appear in the printer's print queue, the jobs will be printed, even if you disconnect the printer.

To disconnect a printer:

1.	In the Network Printer Connections dialog, select the printer to disconnect.

The printer is highlighted and the Disconnect button is activated.

2.	Choose Disconnect.

The printer is disconnected and removed from the list of printer connections.

2.	Start  the DOS Print utility by double-clicking its icon.

The DOS Print icon appears minimized on your desktop.

3.	Open a DOS box and start a DOS application.

4.	From within the DOS application, issue a print command.

The DOS Print redirector directs the print job to the default printer.

Tip: If you find that individual DOS print jobs are not printing completely, or that multiple DOS print jobs are being concatenated, enter a longer time out interval in the DOS Print Redirector dialog box.


Troubleshoot Printing Problems

Problem	Possible Causes	Solution
Cannot reach host.	The print server, the network, or part of the network is not working.	Ask your network administrator for the name of a working LPD print server.
Cannot find host.	Your computer cannot find an internet address for the print server in the name service (NIS, DNS, or hosts file).	Use ping to make sure you can reach the print server. Ask your network administrator for the name of a working LPD server.
Cannot connect to printer.	You mistyped the print server or printer name.	Retype the correct printer and server names.
Cannot print.	The print queue does not exist on the host system running the print server.	On UNIX systems, the printer name must have an entry in the printer database, the /etc/printcap file on the host system.  Ask your network administrator for the correct printer name.
	The LPD print server is not running on the remote host.	On a UNIX print server, type this command to see if LPD is running: ps -ef | grep lpd Ask your network administrator for the name of a working LPD server.
Cannot print from an application.	You tried to print using a printer that is not configured on your PC.	Use Print Manager to connect your PC to the network printer;  then print from the application.
		Use the application to print to a file; then print the file with LPR QuickPrint.
Postscript files do not print.	The Windows PostScript driver adds Ctrl D characters to the beginning of a print job.  If LPD is running on a UNIX machine, the Ctrl D characters indicate the end of a file and the file is not printed.	Remove the Ctrl D characters from print jobs by inserting this line in the [PrintDriver,Port] section of the win.ini file: CtrlD=0 PrintDriver is the name of the PostScript printer driver and Port is the name of the local port that you want to use.   If the section does not exist, create it (get the driver name from the [devices] section of the file).  For example, the following section removes the Ctrl D characters from print jobs sent to an Apple LaserWriter driver being used on port LPT1: [PSCRIPT,LPT1] CtrlD=0 For more information about printing using Windows, see the WINDOWS\printers.wri file
