RetroBSD: Run aged BSD Unix on a microcontroller


Modern microcontrollers are apropos utterly beefy. The Microchip PIC32 line is indeed an doing of a MIPS32 4K design – and with 512K of peep and 128K of RAM we can even run Unix! RetroBSD is a pier of BSD 2.11 for a PIC32. You competence not be means to run X11, though it is still really useful and a good sign of how tiny Unix used to be – and how distant it has come.

Unmatched formula of ICS BANKS® resolution on HP Superdome 2 i4 Unix …

ICS BANKS® Application Achieves Record Breaking Performance and High-watermark Benchmarking on HP Unix Platform 

ICS Financial Systems Limited (ICSFS), the tellurian program and services provider for banks and financial institutions, successfully benchmarked a ICS BANKS® program apartment on HP Superdome 2 i4 Unix environment. 

Performed in Mar 2014, during HP Atlanta Solution Centre in USA, a benchmark suggested high opening scalability of ICS BANKS® and achieved a top and unmatched formula with high series of point connected users and large injection of financial transactions. 

ICSFS generated ICS BANKS® information deputy of tier 1 and tier 2 concept banking activity volumes of 145 million accounts, 3,000 branches and some-more than 42,000 point users. 

With simulating some-more than 42,000 point users, a throughput of 22,056 for OLTP financial exchange was achieved for generation of 35 minutes. The ATM E-channels benchmark suggested an altogether throughput of 63k (62936) exchange per second. End of Month Capitalization Batch processed 4.2 million Interest Accounts in 4 mins window ensuing in an unmatched collection throughput of 59k (59200) accounts per second. 

ICS BANKS® Internet Banking (IBS) benchmark totalled a online estimate window, installed with some-more than 61,000 point users with 45 million purebred users. The complement upheld around 422,000 user logon and 23 million web page visits within 30 minutes. During this test, a throughput of 5.3k (5338) online financial exchange per second is postulated ensuing in 9.6 million online exchange within a 30-minute window. This exam totalled a scalability and sustainability of ICS BANKS® Internet Banking to offer large clients over 30 mins while still ensuring fit use smoothness but any detriment of speed or peculiarity of service. 

This opening benchmark reflects ICS BANKS® high scalability and lively of providing high levels of operational efficiency, assembly finish users ever-changing final and elaborating business requirements, and delivering absolute banking solutions designed for a world’s largest banks. Sustaining extraordinary and unmatched throughput for both online and collection processing, while still ensuring fit use smoothness but any detriment of speed or peculiarity of service, is the highest achieved currently as no publicly accessible benchmark is famous to yield aloft opening for this kind of benchmark. 

Managing Director of ICSFS; Mr. Robert Hazboun commented on this milestone, “Our record violation formula denote that ICS BANKS® can simply hoop a transaction estimate mandate of any bank, anywhere in a world. ICS BANKS® valid a robustness, scalability, potency and agility. ICS BANKS® uses and utilizes a latest record accessible in a marketplace in further to a plain architecture.’’

Mayhem malware ropes Linux, UNIX servers into botnets

A new malware that researchers have dubbed Mayhem is being used to aim Linux and Unix web servers and has so distant compromised over 1,400 Linux and FreeBSD servers around a world, advise researchers from Russian Internet hulk Yandex.

Mayhem has a functions of a normal Windows bot, though doesn’t need base entrance to make use of them. The malware is modular, and can be expected done to do a series of things, though a stream chronicle can:

  • Find websites that enclose a remote record inclusion (RFI) vulnerability
  • Enumerate users of WordPress sites
  • Identify user login pages in sites formed on a WordPress CMS
  • Brute force passwords for sites formed on a WordPress and Joomla CMSs
  • Brute force passwords for roughly any login page
  • Brute force FTP accounts
  • Crawl web pages (both by URL and IP) and remove useful information.

During their investigation, a researchers also rescued that Mayhem is a delay of a Fort Disco brute-force debate unearthed by Arbor ASERT in Aug 2013.

“Initially, a square of malware appears as a PHP script,” a researchers shared. “After execution, a book kills all ‘/usr/bin/host’ processes, identifies a complement design (x64 or x86) and complement form (Linux or FreeBSD), and drops a antagonistic common intent named ‘’.”

New variables, scripts and tasks are created, functions executed and processes run (for in-depth sum check out a researchers’ paper during Virus Bulletin), and a malware contacts a CC server in sequence to send a host’s complement information and accept instructions on what to do next.

The researchers managed to benefit entrance to dual of a 3 CC servers used to conduct a botnet, and have rescued that those dual control about 1,400 bots, many of that were used to beast force WordPress passwords.

“During a analysis, we found some common facilities common between Mayhem and some other *nix malware. The malware is identical to ‘Trololo_mod’ and ‘Effusion’ – dual injectors for Apache and Nginx servers respectively,” they noted, and supplement that notwithstanding a miss of evidence, they think that all these malware families were grown by a same gang.

Yandex researchers weren’t a initial ones to have rescued and analyzed Mayhem – a Malware Must Die group has spotted it scarcely a month earlier. Both teams researched a malware independently.

Yandex researchers charge a rising recognition of botnets done adult of *nix web servers to several factors: Web servers are some-more absolute than typical personal computers and have good uptime; a admins customarily refurbish a program manually and irregularly, permitting enemy to find and feat vulnerabilities; and Web server botnets are ideal for earning criminals income off of trade redirection, drive-by download attacks, black shawl SEO, and so on.

BusyBox crams 117 Unix collection into a little Windows executable


Unix is eminent for a absolute authority line tools, and there are many ways we can try during slightest some of them on a PC. Installing Gnu on Windows gets we 100+ of a best famous tools, recompiled to run underneath Windows, while favorites like grep have been ported individually.

But if you’re looking for morality and convenience, it’s tough to kick BusyBox, that crams little versions of 117 Unix utilities into a singular 645 KB executable. There’s no bulk, no formidable folder structure, only one package that provides all we need.

You don’t need any Unix/ Linux believe to get during slightest something from a program, as many of a commands are really simple. Cal displays a content calendar (month or year); df and du promulgate tough expostulate use; conduct displays a initial 10 lines of a content file; nap pauses your book for a tangible time; unzip extracts files from archives, and so on.

If you’re gentle during a Windows authority line afterwards you’ll conclude BusyBox’s some-more modernized tools. Diff compares content files and displays their differences; ftpput and ftpget store and collect files around ftp; grep is a absolute hunt apparatus with unchanging countenance support; hexdump displays files in several tradition formats; and there are smarter ways to duplicate files, review them, and generally take improved control of your system.

Linux experts should keep in mind that BusyBox has been optimized for size, and a collection generally don’t have as many options as a originals. The module is some-more about preference and portability than ancillary each singular discretionary switch.

For all that, many collection keep their core features, and BusyBox does support a lot of utilities:

[, [[, ar, ash, awk, base64, basename, bash, bbconfig, bunzip2, bzcat, bzip2, cal, cat, catv, chmod, cksum, clear, cmp, comm, cp, cpio, cut, date, dc, dd, df, diff, dirname, dos2unix, du, echo, ed, egrep, env, expand, expr, false, fgrep, find, fold, ftpget, ftpput, getopt, grep, gunzip, gzip, hd, head, hexdump, kill, killall, ls, lzcat, lzma, lzop, lzopcat, man, md5sum, mkdir, mktemp, mv, od, patch, pgrep, pidof, printenv, printf, ps, pwd, rev, rm, rmdir, sed, seq, sh, sha1sum,  sha256sum, sha3sum, sha512sum, shuf, sleep, sort, split, stat, strings, sum, tac, tail, tar, tee, test, touch, tr, true, uname, uncompress, unexpand, uniq, unix2dos, unlzma, unlzop, unxz, unzip, usleep, uudecode, uuencode, vi, wc, wget, which, whoami, xargs, xz, xzcat, approbation and zcat

That’s a lot to learn, though we can collect out a collection we need, and a module comes with a possess simple help. Enter BusyBox during a authority line to see a full list of utilities, or supplement a duty name — BusyBox grep — for sum on accurately what we can do.

Oh SNAP! Old-school ’80s Unix penetrate to pound OSX, iOS, Red Hat?

The pierce to DevOps

Unix-based systems, as used worldwide by sysadmins and cloud providers alike, could be hijacked by hackers abusing a hard-coded vuln that allows them to inject capricious commands into bombard scripts executed by high-privilege users.

A category of vulnerabilities involving supposed wildcards allows a user to impact bombard commands released by other users by filename manipulation. If a other user is a absolved user, such as root, afterwards a tactic could be used to run betterment of privilege-style attacks.

In a context of programming a wildcard is a character, or set of characters, that can be used as a deputy for some other operation or category of characters. Wildcards are interpreted by a bombard book before any other movement is taken.

The old-school hacking technique, unclosed by confidence researchers during DefenseCode, uses specifically crafted filenames featuring wildcards to inject capricious arguments to bombard commands run by other users.

DefenseCode’s whitepaper contains examples for opposite Unix commands and their impact if used in multiple with wildcards. All Unix derivatives are potentially vulnerable.

Although it competence during initial seem that a smirch usually affects badly-coded bombard scripts that are executed by a aloft absolved user, implying that it’s not generally serious, a outcome could go deeper than that, according to third-party investigate of a disadvantage by confidence consultancy SEC Consult.

SEC Consult reckons a disadvantage has implications for a foot and shutdown sequences of servers using with high privileges on many Unix-like handling systems.

The bug potentially affects Android, iOS, OS X and all a embedded solutions using on Linux. Oracle, RedHat and other blurb Linux formed systems competence also be during risk.

“Many of these handling systems have opposite bombard utilities and collection usurpation even some-more authority line options,” SEC Consult records in a blog post “A brief check on Ubuntu gave us during slightest 5 commands, besides a ones mentioned in a whitepaper, unprotected to this specific problem.”

Cloud service- or web hosting providers using cron jobs for backups and identical tasks competence also be exposed, according to SEC Consult, that argues that a disadvantage is a good claimant for serve research.

“Since this bug originates from a pattern problem it will be unequivocally engaging on how handling complement vendors residence this problem. It is something we can't repair with a elementary patch. The approach on how a complement interacts with files has to be totally redesigned,” SEC Consult writes.

“This is a ‘feature’ that has been benefaction here given emergence of a internet, though nobody unequivocally attempted to injustice it previously,” explained Leon Juranic, arch exec of DefenseCode, in an email to El Reg.”It is both hacking technique and tangible vulnerability/weakness of Unix systems. Probably all Unix distributions are unprotected to this.”

“We wanted to surprise all vital *nix distributions around a obliged avowal process about this problem before posting it,” he added, “because it is rarely expected that this problem could lead to internal base entrance on many distributions. But, given partial of this investigate contained in a request was mentioned on some blog entries, we are forced to recover it in a full version.”

Juranic combined that a new recover of similarly-themed third-party research stirred DefenseCode to recover the investigate – that it had been operative on given Apr 2013 – progressing than it primarily intended. ®

Engaging Suffering: Philippe Pasqua during UNIX Gallery

According to Mary Anne Staniszewski’s book Believing Is Seeing, “art”, as we perspective it, did not start building until around a time of a French Revolution.  She argues that a arise of a center category art marketplace liberated a artist to arise his/her possess themes and concepts.  Instead of a few congregation describing a work they wanted, artists could now openly emanate what they wanted to and offer pieces in a marketplace place for folks to name from – this lead to larger foe and investigation (she argues that developments in western art have always been contingent on developments in western politics and a economy).

I discuss this since UNIX Gallery points out in their press recover that as good as being deeply shabby by a work of Francis Bacon, Philippe Pasqua follows in a tradition determined by Courbet in his choice to paint those who have not been entirely embraced, if embraced during all, by society.  What we consider is provocative is that, if we consider about it, scarcely a whole story of art before Daumier and Courbet definitely ignores amicable pang or those who had been marginalized or victimized by other segments of multitude (the usually pang decorated seems to have been a pang of Jesus, Christian martyrs, people in ruin or imaginary figures).  Even when Velasquez embellished his peasants, they had vast ol’ smiles on their faces as if all in their lives was only fine. With a arise of a center category and deputy supervision in a 1800s, we also get a origination of a journalistic regard for identifying and elucidate amicable problems.  The depiction of amicable suffering, suddenly, in a 1800s, became fascinating (or during slightest marketable) in art.

Philippine , 2012, Oil on canvas, 104.5 x 79 in

Philippine , 2012, Oil on canvas, 104.5 x 79 in

What we consider is interesting, though, is that Pasqua’s art deviates in a suggestive approach divided from this tradition.  In a UNIX uncover there are vast paintings of immature people who seem to be in low psychological pain, experiencing some form of startle or expressing some form of horror.  What helps give these portraits additional energy is that they are totally distant from any context. We do not know what generated a romantic response we understand on a face of a chairman depicted.  As a contrast, when we demeanour at, for instance, a famous print display a countenance on a face of a Vietnamese child burnt by napalm, a context subsumes approach rendezvous with a child’s suffering.  This is a print that is an complaint of war, it is not a print indispensably meant to pierce us closer to a knowledge or amiability of a child.

John Locke forked out that when we declare suffering, we humour as well.  We don’t humour to a same degree, though we are emotionally harm when we see others who are in pain.  So depicting pain allows an artist to emanate an evident romantic rendezvous between his/her work and a viewer.  But we consider that Pasqua goes even one step farther.  It’s roughly as if he invites us, by his portraits, to try what a early psychoanalysts attempted to do.  According to Jung’s judgment of ‘the bleeding healer’ a therapist has to pierce over small care and a pain Locke described and truly feel a specific pain or specific fear that a studious is feeling.  Only by joining on this low turn could a patient’s pain or romantic pang be erased by a therapist.  It’s as if Pasqua’s paintings plea us to try to bond on low levels with those who are suffering, maybe as a form of self-therapy or as a approach to arise a larger clarity of amiability and rendezvous with others.

Untitled , 2012, Oil on canvas, 40 x 33 in

Untitled , 2012, Oil on canvas, 40 x 33 in

Furthermore, by not meaningful a context of a pang individuals, we are intent in a approach that prevents us from stealing a source of a pain.  The artists and photographers who have documented a amicable context causing a pain of their subjects, as good as a pain itself, indicate that we, a viewer, can mislay this source of pain.  This seems to be a raison d’etre for such photos – to call recognition to conditions causing pain so a conditions can be removed.  But often, we, as individuals, are infirm to mislay this source of pain.  Often we live among detachment or self-absorption and can do small ourselves.  We, as individuals, are unable to stop a war, to discharge poverty, to finish interpersonal cruelty. Perhaps Pasqua is indicating to a form of pomposity in a really act of documentary broadcasting – to what border are these reporters exploiting those who humour to yield viewers with a appreciative clarity that a problem has been documented (by a favourite artist) and will shortly be finished (somehow). To what border is documentary photography/art feeding a lust for cocksure pity, while we live securely, detached from a suffering?

Untitled , 2012, Oil on canvas, 40 x 33 in

Untitled , 2012, Oil on canvas, 40 x 33 in

Also, we consider an import of Pasqua’s work could be that a artists who have decorated amicable pang in a past were too deeply shabby by artists who decorated eremite suffering.  When we demeanour during Jesus on a cranky or a case being tortured to death, we are looking during an ‘other’ – a form of higher being who done a scapegoat you’ll never make.  You are to honour and commend this picture of suffering.  You feel empathize for a bold case who took a step that lead to his/her death.  Basically, art and detailed pieces that uncover a case within a amicable context of pang is too tighten to this eremite depiction of suffering.  The small Jewish child in a Warsaw poor with his hands in a atmosphere and a demeanour of fear on his face is a ‘other’ who is to be pitied only as a Vietnamese lady was to be pitied.

So a genuine value of Pasqua’s work, in my opinion, is that he wants us to pierce over empathize and compassion. He wants us to pierce over observation those who humour as ‘others’ and to try a deeper connection. He also examines a border to that this tie is probable and what a subsequent moves competence be, as amicable actors, after this low rendezvous with a unpleasant emotions of others.  Perhaps his work points to a need for larger collaborative bid on a partial of those who are peaceful to deeply feel a fear and pain that others confront customarily around a world.

Unfortunately, due to a chaotic May, we was not means to get to this uncover progressing and by a time we review this a uncover will have closed.  Please put this artist on your radar shade however – he is doing some extraordinary work.

Beware of variable differences between Unix and Linux

With Linux fast replacing Unix on server platforms, Unix veterans competence find a differences
between Unix and Linux are tough to get used to.

The truth behind any Unix chronicle is that the
vendor takes finish care

of a customers. Unix creates program accessible as a exclusive apparatus to
guarantee a integrity. The Linux truth is that
everything is open source; a source formula of drivers and other program components contingency be
accessible for users to confederate them optimally.

The dual platforms demeanour a lot alike, though there are many small and defining differences between
Unix and Linux that means problems if you’re not wakeful of them.

Several Unix collection are noticeably absent on Linux servers. Unix admins use EMC’s PowerPath to
set adult a surplus storage area network (SAN) tie to a servers, for example. On Linux,
there is no PowerPath doing available. High-performance record systems and volume managers,
which we competence have purchased with high permit fees for your Unix servers, are blank on common
Linux distributions. Does that make Linux an defective platform? Chances are it’s usually different
from what we expected.

The vital disproportion between Linux and Unix is that all on Linux is open source, and
therefore accessible for free. Paying thousands of dollars for a apparatus on your comparison servers leaves a
bitter ambience in your mouth. Consider PowerPath for instance: All Linux distributions have a native
tool — a Device
Mapper Multipath driver
— that is as good as PowerPath. Even EMC recommends we bond Linux
servers to a SAN regulating a multipath driver.

On Linux servers, volume government eliminates purchasing costly additional licenses to
organize your storage in volumes. Linux comes with a Logical Volume
that includes all to set adult storage flexibly. Unix administrators typically
don’t have a problem operative with these tools, though they also don’t trust that a giveaway and open
source setup is as effective as a costly exclusive solution.

In some cases, specific exclusive program modules are accessible for a Linux distribution.
They typically come with a hardware we purchase. If that hardware is on your Linux
distribution’s hardware-support list, we won’t have any problems. Your Linux businessman collaborates
with a hardware businessman for optimal operation and support. Proprietary modules from hardware
vendors mostly are upheld usually for
enterprise Linux distributions
including SUSE, Oracle, Ubuntu and Red Hat. Free distributions
may not work good on this hardware.

Unix administrators typically guard their IP pattern with the
ifconfig command
. On Linux, ifconfig exists as well, though has been deprecated given a release
of a 2.0 heart in 1996. Since then, a ip
is a usually approach to guard all that’s function on your servers. This versatile
command has several options for handling network configuration.

Even if you’re an gifted Unix administrator, cruise emigration training so that your
skills comparison these differences between Unix and Linux.
