FSIRAND.FFS(1M)     RISC/os Reference Manual      FSIRAND.FFS(1M)



NAME
     fsirand.ffs - install random inode generation numbers

SYNOPSIS
     fsirand.ffs [ -p ] special

DESCRIPTION
     fsirand.ffs installs random inode generation numbers on all
     the inodes on device special, and also installs a filesystem
     ID in the superblock.  This helps increase the security of
     filesystems exported by NFS.

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

OPTIONS
     -p   Print out the generation numbers for all the inodes,
          but do not change the generation numbers.
