fsirand(1M)                                           fsirand(1M)



NAME
     fsirand - installs random inode generation numbers

SYNOPSIS
     fsirand [-p] [-Tfs-type] special

ARGUMENTS
     -p   Prints out the generation numbers for all the inodes,
          but does not change the generation numbers.

     special
          Specifies the device name.

     -Tfs-type
          Indicates the file-system type, for example 4.2 or 5.2.
          If this option is not present, fsirand attempts to
          determine the file-system type.

DESCRIPTION
     fsirand installs random inode generation numbers on all the
     inodes on device special and also installs a file-system ID
     in the superblock.  This helps increase the security of file
     systems exported by the network file system (NFS).

     The fsirand must be used only on an unmounted file system
     that has been checked with fsck(1M).  The only exception is
     that it can be used on the root file system in single-user
     mode, if the system is immediately rebooted afterward.

FILES
     /etc/fsirand
