AFS is a distributed filesystem product, pioneered at Carnegie Mellon
University and supported and developed as a product by Transarc Corporation
(now IBM Pittsburgh Labs). It offers a client-server architecture for
federated file sharing and replicated read-only content distribution,
providing location independence, scalability, security, and transparent
migration capabilities. AFS is available for a broad range of heterogeneous
systems including UNIX, Linux, MacOS X, and Microsoft Windows.
IBM branched the source of the AFS product, and made a copy of the source
available for community development and maintenance. They called the
release OpenAFS.
gwhois is a generic whois client. It strives to know for all existing
tlds and all ip address range the appropiate whois server to ask. You
can simple call gwhois with a query for some domain or some ip and it
will ask the right server for you! It can even query webforms which
are unfortunately the only query type supported by many bad nics.
gwhois can also be used as a whois server. You can call it from the
inetd and make it accessable via a normal standard whois client. This
allows for example using a Windows client and still make use of the
enhanced features of gwhois.
This module provides a simple functional "named parameters" style interface
for creating URIs. Underneath the hood it uses URI.pm, though because of
the simplified interface it may not support all possible options for all
types of URIs.
It was created for the common case where you simply want to have a simple
interface for creating syntactically correct URIs from known components
(like a path and query string). Doing this using the native URI.pm
interface is rather tedious, requiring a number of method calls, which is
particularly ugly when done inside a templating system such as Mason or
TT2.
rsync is a replacement for rcp that has many more features.
rsync uses the "rsync algorithm" which provides a very fast method for
bringing remote files into sync. It does this by sending just the
differences in the files across the link, without requiring that both
sets of files are present at one of the ends of the link beforehand.
This makes rsync a good remote file distribution/synchronization utility
in a dialup PPP/SLIP environment.
Note, requires rsync on the destination machine.
There is a Computer Science Technical Report on the rsync algorithm is
included in the distribution, and is available as
ftp://samba.anu.edu.au/pub/rsync/tech_report.ps
The vblade is the virtual EtherDrive (R) blade, a program that makes a
seekable file available over an ethernet local area network (LAN) via
the ATA over Ethernet (AoE) protocol.
The seekable file is typically a block device like /dev/md0 but even
regular files will work. Sparse files can be especially convenient.
When vblade exports the block storage over AoE it becomes a storage
target. Another host on the same LAN can access the storage if it has
a compatible aoe kernel driver.
utftpd is a TFTP server with fine-grained access control, support for
blksize (RFC 2348), timeout options and support for revision control.
You can assign three different kinds of rights to every client:
- read: the right to read a file.
- write: the right to write to an already existing file.
- create: the right to create a file.
Clients may be specified by a single ip address or a range of
addresses or by ip address and mask.
Revision control is optional and will never be turned on automatically
for any file (you have to do the initial checkin into by hand).
Wackamole is an application that helps with making a cluster highly
available.
It manages a number of virtual IPs, that should be available to the
outside world at all times. Wackamole ensures that a single machine
within a cluster is listening on each virtual IP address that Wackamole
manages. If it discovers that any particular machine within the cluster
are not alive, it will almost immediately ensure that other machines
acquire their public IPs. At no time will more than one machine listen
on any virtual IP.
Wackamole also works toward achieving a balanced distribution of the
numbered IPs on the machine within the cluster it manages.
PostScript::Simple allows you to have a simple method of writing
PostScript files from Perl. It has graphics primitives that allow lines,
curves, circles, polygons and boxes to be drawn. Text can be added to
the page using standard PostScript fonts.
The images can be single page EPS files, or multipage PostScript files.
The image size can be set by using a recognised paper size ("A4", for
example) or by giving dimensions. The units used can be specified ("mm"
or "in", etc) and are the same as those used in TeX. The default unit is
a bp, or a PostScript point, unlike TeX.
PyScript is a python module for producing high quality postscript
graphics. Rather than use a GUI to draw a picture, the picture is
programmed using python and the PyScript objects.
Some of the key features are:
* All scripting is done in python, which is a high level, easy
to learn, well-developed scripting language.
* All the objects can be translated, scaled, rotated, ... in fact
any affine transformation.
* Plain text is automatically kerned.
* You can place arbitrary LaTeX expressions on your figures.
* You can create your own figure objects, and develop a library
of figure primitives.
* Output is publication quality.
This is a set of three simple tools written in sh(1) for generating single
patches for use in Ports. This set is ideal for creating a new patch when
it is inconvenient or undesirable to use the "make makepatch" utility.
The first tool is "dupe" which is a quick copy utility. The second tool
is "genpatch" which creates patches in the standards diff format and
using the standard file name conventions. The last tool is "portfix"
which runs "dupe", an editor of choice, and "genpatch" serially as a
macro as a convenient and quick way to create port patches.
Please see the dupe, genpatch, and portfix man pages for details.
