iSeries NetClient file system (QNTC)

 

The QNTC file system provides access to data and objects that are stored on an Integrated xSeries^® Server for iSeries™ running Windows NT^® 4.0 Server or later, or Linux^®. The QNTC file system also provides access to data and objects that are stored on remote servers running Windows NT 4.0 or later, Linux Samba 3.0 or later, or supported versions of iSeries NetServer™.

The QNTC file system allows i5/OS^® applications to use data stored on Windows^® or Linux servers.

The QNTC file system is part of the base i5/OS operating system. It is not necessary to have the Integrated Server Support, option 29 of the operating system, installed to access /QNTC.

 

Accessing QNTC through the integrated file system interface

By using the iSeries NetServer, iSeries Navigator, integrated file system commands, user displays, or APIs, you can access the QNTC file system through the integrated file system interface.

Be aware of the following considerations and limitations.

• Authorities and ownership in the QNTC file system
  The QNTC file system does not support the ownership concept of a file or directory.

• Case-sensitivity in the QNTC file system
  The QNTC file system preserves the same uppercase and lowercase form in which object names are entered, but does not distinguish between uppercase and lowercase in the names.

• Path names in the QNTC file system
  The path consists of the file system name, the server name, the share name, the directory and subdirectory names, and the object name.

• Links in the QNTC file system
  The QNTC file system supports only one link to an object. You cannot create or store symbolic links in QNTC.

• Integrated file system commands and displays in the QNTC file system
  Many integrated file system commands and displays are valid in the QNTC file system

• QNTC environment variables
  The network browsing behavior of QNTC can be controlled by two environment variables. Support for these environment variables began in i5/OS V5R4. Use the ADDENVVAR CL command to create these environment variables.

• Creating directories in the QNTC file system
  You can use the Create Directory (MKDIR) command or mkdir() API to add a server directory to the /QNTC directory.

• Integrated file system APIs in the QNTC file system
  Many integrated file system APIs are valid in the QNTC file system.

• Enabling QNTC file system for Network Authentication Service
  The QNTC file system enables System i™ platform access to Common Integrated File System (CIFS) servers that support the Kerberos V5 authentication protocol.
