PROGRAM: NetNuke
LICENSE: GNU/GPLv3
PURPOSE: Erases all storage media deteced by the system

BUGS
----
- SATA devices are not supported on BSD until code can be implemented to fix
a device iteration failure. /dev/ad0 is the start of IDE. /dev/ad4 is the
start of SATA. Linux should remain OK.
- If a SCSI bus failure occurs, NetNuke does not know to skip its current
device (yet).
OPERATING SYSTEMS SUPPORTED
---------------------------
BSD:
FreeBSD - Works
OpenBSD - Not Tested, and will not work yet.
NetBSD - Not Tested, and will not work yet.
Linux:
2.4 - Not Tested, and may not work
2.6 - Works, but needs more testing
OPTION REFERENCE
----------------
--help
Display NetNuke application options, and exit.
--write-mode [s] or -w [s]:
Accepts a 32-bit integer value.
0: Synchronous
Data is immediately committed to the disk.
1: Asynchronous
Data is buffered, and is committed to the disk over time. (Very fast)
Default: 0
--nuke-level [n] or -nl [n]
Accepts a 32-bit integer value.
0: Zero out
- Write zeros across all devices.
1: Static patterns
- One of the 24 patterns are selected per device (or per write pass).
Pattern table is as follows:
0xA0, 0xB0, 0xC0, 0xD0, 0xE0, 0xF0,
0xA1, 0xB1, 0xC1, 0xD1, 0xE1, 0xF1,
0xA2, 0xB2, 0xC2, 0xD2, 0xE2, 0xF2,
0xA3, 0xB3, 0xC3, 0xD3, 0xE3, 0xF3
2: Fast random
- A random buffer is generated, and the data is written across all
devices.
3: Slow random (regenerate random buffer)
- A random buffer is regenerated every 128 completed write operations.
4: Ultra-slow re-writing method
- NOT IMPLEMENTED (defaults to static pattern method)
Default: 1
--passes [n] or -p [n]
Accepts a 32-bit integer value.
This options defines the number of full passes NetNuke should perform on
a single device during its operation.
Default: 1
--disable-test
USE WITH EXTREME CAUTION!
Test-mode is disabled, and all write operations are allowed to begin.
Default: NetNuke writes all test iterations to /dev/null
--block-size [n] or -b [n]
Accepts a 32-bit integer value.
This option defines the number of device blocks NetNuke should attempt
to wipe.
Default: 512
--verbose or -v
Enables verbose messages
Default: off
--verbose-high or -vv
Enables a high degree of verbose messages. The output will obstruct any usable
human-readable data, as well as cause the write operation to slow down to a
crawl.
Default: off
--version or -V
Display NetNuke's version and license, then exit.
