Tool

This is a tool that retrieves and displays the data kept in the netware.metadata extended attribute on an NSS file on a Linux server. The utility was designed to help developers use the getxattr API with NSS volumes. The ability for OES servers to use the getxattr() API for NSS volumes has been added to SLES 9 OES1 SP2 with the following patches and parameters:

• For the this Utility to work on SLES 9 OES1 SP2 the kernel needs to be at the 282 (2.6.5-7.282).

• km-nss-4.9.26-0.1.i586.rpm
• novell-nss-4.9.23-1.i586.rpm
• novell-sms-zapishim-2.6.5_7.282-1.0.5.i586.rpm

NSS must be installed and running.

• The following parameters must be set from NSSCON
  • NSS /ListXattrNWMetadata
  • NSS /CtimeISMetadataModTime

How to Use the file:

From a terminal type:
getxattrs path/fileName.ext <enter>
Where path/fileName.ext is the name of an NSS file that exists on an NSS volume on a Linux Server.

Example: getxattrs /VOL1/file.txt <enter>

Sample output:

grep57:/xattr # ./getxattrs /media/nss/NSS1/file.txt
The file /media/nss/NSS1/file.txt has the extended attribute(s) netware.metadata (the string takes up 17 bytes).
There are 192 byts of data in the netware.metadata extended attribute(s).

A dump of the extended attribute netware.metadata is the following:
