NAME

fsirand - install random inode generation numbers

SYNOPSIS

/usr/sbin/fsirand

[-p] special

DESCRIPTION

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

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.
