encfs - encrypted virtual filesystem
EncFS integrates file system encryption into the Unix(TM) file system. Encrypted data is stored within the native file system, thus no fixed-size loopback image is required.
EncFS uses the FUSE kernel driver and library as a backend. You may need to install the kernel modules, running "module-assistant a-i fuse".
Install encfs in Debian
#apt-get install enfs
For more options and how to use check encfs man page
ethtool - Display or change ethernet card settings
ethtool is used for querying settings of an ethernet device and changing them.

However, backward compatibility is ensured on 2.2 kernel running Sparc with SUN Happy Meal (hme) Ethernet card.
Install ethtool in Debian
#apt-get install ethtool

fakeroot - Gives a fake root environment
This package is intended to enable something like:
i.e. to remove the need to become root for a package build. This is done by setting LD_PRELOAD to libfakeroot.so, which provides wrappers around getuid, chown, chmod, mknod, stat, and so on, thereby creating a fake root environment.
fakeroot requires SYSV IPC to operate.
Install fakeroot in Debian

fdflush - Flush out-of-date disk buffers
fdflush is a band-aid for floppy (or other) drives with bad disk-change sensing. fdflush makes the system believe the disk-change switch has been triggered forcing the system to discard the buffered data.
If you have one of these slightly-broken disk drives, you'll have to run fdflush every time you change a disk.
fdflush is useful for computers which might be sleeping when you change floppies or other removeable media.
The command "floppycontrol -f" does the same thing, but the fdutils package is significantly larger; it only uses the floppy-specific flush ioctl.
The command "blockdev --flushbufs" only uses the generic flush ioctl.
Install fdflush in Debian
#apt-get install fdflush
For more information and how to use check fdflush man page
fdupes - Identifies duplicate files within given directories

floppybackup - Floppy backup using a diversity of floppy formats
This little package was hacked together because all the more sophisticated backup systems were more suited for tape drives and such, and even if they supported floppies, verify mode was either lacking or missing, and mixed-size floppies caused problems.

uses 2048 bytes for the header and 24 bytes per record.
- Maximum database size is 4GB; individual record size is not
- Portable file format.
- Fast creation of new databases.
- No locking, updates are atomical.
This package contains both the utilities and the development files.
