96 SunPCi III 3.2.1 User’s Guide • March 2004
Using SunFSD for Mapping Between
Solaris and Microsoft Windows
The SunPCi III 3.2.1 software includes the Sun File System Driver (SunFSD), which
maps Microsoft Windows drive letters to Solaris software directories.
The administrator should disable client logins prior to enabling SunFSD.
Additionally, after any update (or other activity) is complete, the administrator
should delete or unmap all SunFSD drives, disable mapping in SunFSD, and reboot
the system.
For SunPCi III 3.2.1 installations, the SunFSD mapping function is disabled by default
in the supported Microsoft Windows server products.
Thus, while running one of the server variants of Microsoft Windows, any mapping
of the \\localhost directory by any user (or program), including the
administrator, will fail. Further, any reference or any attempt to access files using a
Universal Naming Convention (UNC) path that includes \\localhost as the UNC
prefix will also fail.
The mapping control is imposed for security reasons. In the current release of
SunFSD, any mapping or file access through \\localhost inherits the privileges of
the user or process that launched the SunPCi III software. Therefore, if the SunPCi
III card is running a Microsoft server operating system, and SunPCi software was
launched under the root account, ordinary server users inherit root privileges across
the network.
SunFSD is enabled on Windows XP Professional and Windows 2000 Professional,
because there are no multi-client file system security issues when using these
operating systems. You can continue to map SunFSD drives in Windows XP
Professional and Windows 2000 Professional the same as you did in previous
releases of SunPCi.
For server installations that require access to Solaris directories, server
administrators can use a package such as Solaris PC NetLink or Samba that employs
per-client security credential verification, or a Citrix MetaFrame client that maps
Microsoft Windows drive letters as the local user.
▼ How to Enable SunFSD Mapping
The main reason for an administrator to enable SunFSD is that SunFSD functionality
is required to execute the update drivers script, as well as other SunPCi supplied
scripts.
