NAME [Toc] [Back]
fsirand - install random inode generation numbers
SYNOPSIS [Toc] [Back]
/usr/sbin/fsirand [-p] special
DESCRIPTION [Toc] [Back]
fsirand installs random inode generation numbers on all the inodes on
device special, and also installs a filesystem ID in the superblock.
This process increases the security of filesystems exported by NFS.
Use fsirand only on an unmounted filesystem that was checked with fsck
(see fsck(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
afterwards using reboot -n.
The -p option prints the generation numbers for all inodes.
WARNINGS [Toc] [Back]
fsirand is only supported on HFS filesystems. fsirand should not be
run on mounted filesystems. If executing fsirand on the root
filesystem, the system should be in single-user mode and should be
re-booted immediately afterwards, using reboot -n.
