NAME
fsirand
- install random inode generation numbers in a filesystem
SYNOPSIS
fsirand
[-F]
[-p]
[-x constant]
special
DESCRIPTION
fsirand
writes random inode generation numbers for all the inodes on device
special.
These random numbers make the NFS filehandles less predictable, increasing
security of exported filesystems.
fsirand
should be run on a clean and unmounted filesystem.
The options are as follows:
- -F
-
Indicates that
special
is a file system image, rather than a device name.
special
will be accessed
`as-is',
without requiring that it is a raw character device and without
attempting to read a disklabel.
- -p
-
Print the current inode generation numbers; the filesystem is not modified.
- -x constant
-
Exclusive-or the given constant with the random number used in the generation
process.
fsirand
exits zero on success, non-zero on failure.
If
fsirand
receives a
SIGINFO
signal, statistics on the amount of work completed and estimated
completion time (in minutes:seconds) will be written to the standard
error output.
