This little program polls network statistics and does a few things with
the data it gets. It has small blinking lights for the rx and tx of IP
packets, a digital speedometer of your polled stat's current speed and a
bar graph like xload et. al which has a tx speed graph from bottom-up
and rx speed graph from the top-down. The speedometer keeps track of the
current speed per second and shows it in a color corresponding to which
of rx or tx that has the highest speed at the moment. Also, the graph is
drawn in a way that the highest speed is drawn on top of the other while
the other is in the background.
cdlabelgen's purpose in life is twofold:
o To be run automatically and swiftly from a shell script
and automatically generate a frontcard and a traycard
for a cd--usually data archive cd's. The traycard
(which goes behind the CD itself) is U-shaped and the
ends of the CD case bear the label of what the CD is.
o To have a minimum of dependencies--cdlabelgen only
requires perl.
cdlabelgen was designed to simplify the process of
generating labels for CD's. It originated as a program to
allow auto generation of frontcards and traycards for CD's
burned via an automated mechanism (specifically for
archiving data), but has now become popular for labelling
CD compilations of mp3's, and copies of CDs. Note that
cdlabelgen does not actually print anything--it just spits
out postscript, which you can then do with as you please.

This port contains a script to generate portaudit reports for jails
running on a FreeBSD system.
Normally portaudit just creates reports for the Host-system or the jail
it is installed in. With a large number of jails running on a system,
installing and updating portaudit in every jail is time-consuming and
error-prone. Jailaudit uses the portaudit installed in the Host-system
to create a report for every jail.
The reports are appended to the daily security run and can be sent to a
specific mail address, which allows the Host-system administrator to
dispatch portaudit reports to the owners of jails, keeping them informed
about potential security advisories of their installed ports.
Jailaudit can be used on FreeBSD 5.1 or larger.
fswatch:
- is a utility to guard changes in a file system.
- is composed of three simple programs: fswbuild, fswcmp, fswshow. fswbuild
builds a file system information database. fswcmp compares two database files
and returns what changes a in file system have been introduced. fswshow shows
contents of database file. a file information database is platform
independent.
- can collect the following information about files (and directories): inode,
links, uid, gid, mode, size, flags, ctime, checksum (sha1) ; and can show
which files were added, deleted or changed.
- is one of many similar utilities. the main difference is the configuration.
you can define different settings for every directory in a directory tree.
moreover, it is very small and fast.
Eksblowfish is a variant of the Blowfish cipher, modified to make the
key setup very expensive. ("Eks" stands for "expensive key
schedule".) This doesn't make it significantly cryptographically
stronger, but is intended to hinder brute-force attacks. It also
makes it unsuitable for any application requiring key agility. It was
designed by Niels Provos and David Mazieres for password hashing in
OpenBSD.
Eksblowfish is a parameterised (family-keyed) cipher. It takes a cost
parameter that controls how expensive the key scheduling is. It also
takes a family key, known as the "salt". Cost and salt parameters
together define a cipher family. Within each family, a key determines
an encryption function in the usual way.
This distribution also includes an implementation of "bcrypt", the
Unix crypt() password hashing algorithm based on Eksblowfish.
Solitaire is a top-notch pencil-and-paper encryption system developed
by Bruce Schneier. Here is the description in Schneier's own words:
"Solitaire gets its security from the inherent randomness in a
shuffled deck of cards. By manipulating this deck, a communicant
can create a string of "random" letters that he then combines with
his message. Of course Solitaire can be simulated on a computer,
but it is designed to be implemented by hand.
"Solitaire may be low-tech, but its security is intended to be
high-tech. I designed Solitaire to be secure even against the most
well-funded military adversaries with the biggest computers and the
smartest cryptanalysts. Of course, there is no guarantee that someone
won't find a clever attack against Solitaire, but the algorithm is
certainly better than any other pencil-and-paper cipher I've ever
seen."
Simple system, easy to use, and relatively fast.

This utility is a wrapper for the md5(3), sha1(3), rmd160(3), and
tiger hash routines. It is remarkably similar to the digest package,
except that it can recursively checksum directory trees.
While a simple checksum on a tar file is usually satisfactory, once
said archive has been extracted, it is virtually impossible to
repackage the extracted tree in a form that can yield a repeatable
checksum. To be specific, changes in timestamps and ownership, and
changes in file ordering within directories can affect the checksum of
the archive, while not really impacting the actual code at all.
The algorithm used to checksum a directory in this implementation
is considers only the files' pathnames, the files' types (ie,
directory vs. file vs. symbolic link), and their contents (for
the latter two). It is described in greater detail in the man
page.
The cdrtools software includes tools to create and/or extract
ISO-9660 filesystems, verify their integrity, and write them to
disc.
This package contains the following programs:
- btcflash (a firmware flash utility for BTC DRW1008 DVD+/-RW recorder)
- cdda2wav (a digital CD audio extraction program)
- cdrecord (a CD/DVD/BluRay recording program)
- devdump (dump a device or file in hex)
- isodebug (show debug info contained in an ISO-9660 image)
- isodump (dump a device or file based on ISO-9660)
- isoinfo (analyze or list an ISO-9660 image)
- isovfy (verify an ISO-9660 image)
- mkisofs (an ISO-9660 filesystem image creator)
- mkhybrid (an ISO-9660/HFS filesystem image creator)
Link to mkisofs.
- readcd (a data CD reading and recording program)
May be used to write to DVD-RAM and to copy Solaris boot CD's.
- scgcheck (checks and validates the ABI of libscg)
- rscsi (daemon providing access to local SCSI-devices over the network)
clone is a file tree cloning tool which runs 3 threads - a scheduler (main), a
reader, and a writer thread. Reading and writing occurs in parallel. While this
is most beneficial for copying data from one physical disk to another, clone is
also very well suited for cloning a file tree to any place on the same disk.
Cloning includes the whole directory hierarchy, i.e. sub-directories, files,
hard links, symbolic links, attributes (modes, flags, times), extended
attributes and access control lists.
clone is useful for cloning (thus backing-up) live file systems, and it can
also be used in incremental and synchronization mode.
clone works on FreeBSD and Mac OS X.
clone is very fast, for example, cloning a whole UFS2 file hierarchy on
FreeBSD 9.1 of in total 2.3 TBytes of data from one hard disk to another
took 7.5 h, so the average transfer rate for all kind of files (very small
up to very big ones) was about 89 MByte/s.
Actually, we're not trying to reinvent the wheel here,
rather adapt it to suit a slightly different purpose.
Below are a few main points and reasons as to why we've created filetype:
* file does not work so well for loosely defined filetypes ( ie, vCards )
* file uses a text-based type database which can impose unwanted delays
in frequently invoked processes
* file does not have a heirachial type tree (ie, executable->MSDOS->EXE )
* file is not designed to be incorporated at a source level into existing
projects
* Simpler and broader type detection engine ( 'file' is very good at
pulling out every detail about a file, ie, the resolution of an image,
however we do not wish to seek out such fine details )
