NFS Maestro Services
NFS Maestro client configuration service
Note: The NFS Maestro Client service is available if the user has either NFS Maestro Client or the NFS Maestro Gateway Jconfig installed.
Use the NFS Maestro Client service to customize how a user connects to NIS servers. You can configure the following categories of options:
- General server options--Specifies the settings for the authentication of NIS servers and configures other transfer settings.
- File access options--Specifies the default read, write, and execute attributes for the protection of new files.
- Host connection options--Specifies how NFS Maestro handles files when linking to remote hosts. These settings become the default for subsequent NFS mounts of a remote file system.
- Advanced options--Specifies the advanced default client parameters.
- Authentication options--Specifies the order that the client searches for the authentication daemon.
- Locking options--Specifies the default file locking options.
To configure general server options:
Click the Directory Service tab and fill in the required information.
- Service--Select the service you want to use for host name resolution, user password and security key lookup. You can choose from the following services:
- None (HCLNFSD/PCNFSD)--Select this option if NIS or NIS+ is not running on your network.
- NIS--Select this option if you are running NIS on your network. If NIS is not configured, the NIS Properties dialog box opens. To change the NIS configuration, click Properties. For more information about configuring NIS, see Directory Services Explorer online help.
- NIS+--Select this option if you are running NIS+ on your network. If NIS+ is not configured, the NIS+ Properties dialog box opens. To change the NIS+ configuration, click Properties. For more information about configuring NIS+, see Directory Services Explorer online help.
- Properties--Select this option to change the NIS or NIS+ configurations. This option is active only if you have selected NIS or NIS+ on the Services drop-down list.
- Use NIS/NIS+ for host name lookups--Select this option if you want NFS Maestro Client to use the NIS/NIS+ database when looking up a host. This option is active only if you selected NIS/NIS+ as your directory service.
- Synchronize Windows Network password--Select this option if you want to synchronize the user's Windows password with user's NIS password. Changing the windows password automatically changes the NIS password.
Click the Transfer Settings tab and fill in the required information.
- Default Read/Write Size--Specify the amount of data the software asks for (Read) or sends (Write) in a single network read or write request. Some network adapters have difficulty processing back-to-back packets on a send or receive. If your computer hangs when reading or writing large files but works for very small files, this parameter is set too high. Read and Write values range from 512 to 65536 bytes in 512-byte increments. The (NFS Maestro) Parmset application helps determine optimal values.
- Read/Write Parallelism--Displays a range of values from 1 to 8 with 4 being a typical value. Neither the Read nor Write Parallelism value can exceed the Maximum Outstanding Requests value. The (NFS Maestro) Parmset application helps determine optimal values.
- Number of Retries--Specify the number of times a network request is retried before returning a time-out error to the operating system. A typical value for this parameter is 8. Too high a value slows down operation significantly. The (NFS Maestro) Parmset application helps determine optimal values.
- Maximum Reads--Specify the maximum number of network read requests before a response is given. If more than this number of read requests is made at one time, the remaining request threads are queued. This can affect the Default Read Size value, as multiple read requests can be active at one time. The (NFS Maestro) Parmset application helps determine the optimal value.
- Max. Outstd. Reqs. (Maximum Outstanding Requests)--Specify the number of network requests that can be outstanding (not acknowledged) at one time. The range of values is from 1 to 8 with 8 being the default. If more than this number of network requests is made at one time, the remaining requests are queued. This number is equivalent to the number of UNIX BIODs.
To set file access options:
Click the Default Protection tab and select the options you want to enable in the User, Group, and Other sections:
- R--select this option to enable read access by default
- W--select this option to enable write access by default
- X--select this option to enable execute access by default
To set host connection options:
Click the Default Links tab and select the required options:
- Sharing--Select this option to use DOS-style sharing over the network. Normally, all windows file operations are done with DOS-style sharing. In cases where no other users will access the files, consider clearing this option for improved performance.
- Compat. (Compatibility Mode)--Select this option to send all lock requests to rpc.lockd (the UNIX lock manager). By default this option is disabled. NFS Maestro tries to use the daemon hclfnsd for file locking and sharing and uses rpc.lockd when the daemon is not running. If you are running PC clients that cannot access hclnfsd and you are sharing files, select this option so that locking always uses rpc.lockd.
- CD-ROM--Select this option to remove semi-colons and trailing version numbers from remote file names. If you connect to a CD-ROM, consider selecting this option. CD-ROMs sometimes have version numbers appended to the file names with a semi-colon. Also, directories that end in a dot (.) have the dot removed from the file name.
- TCP--Select this option to connect by TCP (Transmission Control Protocol) rather than UDP (User Datagram Protocol).
- Lower, Upper, or Preserve Case--Specifies how file names are handled. Under Windows NT/95/98/2000, NFS-linked file systems support names for files and directories that are not case sensitive and may be up to 255 characters in length.
- Lower Case--By default, NFS Maestro creates new files with file names in lower case. This enables DOS clients to access files from a Windows NT/95/98/2000 machine without name mappings. If you anticipate file exchanges between Windows NT/95/98/2000 users and DOS/Windows 3.x users, select this option.
- Upper Case--Select this option to ensure compatibility with other systems.
- Preserve Case--Maintains the case of the file name when new files are created. If the files are exchanged between UNIX and DOS users, the Lower Case option is recommended.
You can control this behavior for individual network connections with the NFS Network Access application.
To set advanced options:
Click the Advanced tab and select the required options.
Timeouts
The client repeatedly sends network requests for information to the remote host about each file. This information is cached on the client. Timeout values specify how long the client waits before checking whether this information has changed.
Warning: Avoid modifying default timeout values for file name and file attributes unless directed by Hummingbird Technical Support or to resolve specific problems. Contact Technical Support for more information.
- Filename cache timeout--Minimum interval before the client updates file name information.
- File attribute cache timeout--Minimum interval before the client updates file attribute information.
- RPC timeout--Minimum interval before the client sends another RPC request to the portmapper daemon on the server. If the network is slow, consider increasing this value.
Miscellaneous
- Disable NFS Version 3--Select this option if your network is using only NFS Version 2. By default, NFS Maestro uses NFS Version 3.
- Do not use WebNFS--Select this option if the server does not support WebNFS access.
- Do not protect file creation--Select this option only if directed by Hummingbird Technical Support to do so or in special instances to resolve specific problems.
- Warning: In certain circumstances, data may become corrupted if you select Do not protect file creation. Contact Technical Support for more information.
- Ignore execute bit--Select this option to ignore the state of the execute bit. This prevents execution by a UNIX client but lets a PC client execute files.
Special File Name Characters
- Special UNIX Hidden Characters--Type up to 16 characters (such as the default period "." character) which you want to have display for UNIX but not for DOS (PC) clients. Files beginning with this character are marked as hidden for DOS (PC) clients.
- Substitution indicator--Type a character that indicates an NIS map. For example, the default $ character indicates to the NFS Maestro Client that what follows is an NIS map name.
To set authentication options:
Click the Authentication tab and select the required option.
- Protocol--Choose the method by which to perform authentication
- System/UNIX (AUTH_UNIX)--Use the authentication daemons hclnfsd the pcnfsd. Click Properties to open the System/UNIX Authentication Order dialog box which lets you specify how to search for the authentication daemons.
- DES (AUTH_DES)--Secure communications using DES Authentication (secure RPC). You must select NIS+ for Directory Service. Click Properties to open the NIS+ Properties dialog box.
- GSS (RPCSEC_GSS)--Authentication with RPCSEC_GSS security flavor. The RPCSEC_GSS security flavor uses GSS-API interfaces to provide security services that are independent of the underlying security mechanism. You must select NIS/NIS+ for Directory Service. Click Properties to open the NIS/NIS+ Properties dialog box.
- Properties--Select this option to change the authentication order or the NIS+ configurations. The Authentication Order dialog box displays if you specified System/UNIX (AUTH_UNIX). The NIS+ dialog box displays if you specified either GSS (RPCSEC_GSS). For more information, see the NFS Maestro Client and Directory Services Explorer online help.
To set locking options:
Click the Locking tab and select the required options.
- Compatible with PCNFS up to version 1.1, FTP, and Wollongong--masks the high bit of the lock request offset. This is the default option.
- Special locking mode--For environments that cannot use hclnfsd and where the native lock manager does not correctly handle high bit request offsets.
- Native 32-bit locking--The 32-bit lock request is unchanged. This option is recommended where applications (such as Microsoft Word, Microsoft Excel, and WordPerfect) perform standard lock requests.
- Compatible with PCNFS Version 2.0a Pro and Version 5.1a Pro--Masks the high two bits (not just the high bit) of lock request offsets.
NFS Gateway Service
Note: The NFS Maestro Gateway service is available only if the user has NFS Maestro Gateway Jconfig installed.
Use the NFS Maestro Gateway service to configure user connections to the Gateway server. You can do the following:
- Modify NFS Maestro Gateway settings.
- Add a share--The share stores information about the server and the permissions allowed. These permissions apply only to users set up in the Permissions area. Links and shares are automatically reconnected when the machine restarts. You can also add subshares. The subshares option lets you share more than 26 drives. An unlimited number of subshares can be mounted to a single device.
- Add a name mapping--Map a user from the Windows NT environment to the NFS file system. You can map users individually, or automatically map a number of users from a local machine or from a domain with UID and GID values from the network.
For a detailed description of the NFS Maestro Gateway options, see the NFS Maestro Gateway Guide or the NFS Gateway online help.
To modify a setting:
