The work of ages continues as we return (for the last time this month) to our tier list of every-ish cable and connector ever made. Such heavy hitters as DisplayPort, SATA, and USBs both mini- and micro- enter the fray this week, with digressions about obscure entries like the DFP (digital flat panel?) cable, powering bare hard drives straight out of the wall, the all-too-often overly stiff jacket on RJ45 ethernet cables, and more.The Cable Bible: https://amiaopensource.github.io/cable-bible/Recompute's port roundup: https://recompute.co.zw/buying-guides/a-complete-guide-of-every-type-of-computer-port/The current cable tier list: https://tinyurl.com/techpod-cable-rankingsSubmit ideas about secret information encoding in the world around us for an upcoming episode:https://docs.google.com/spreadsheets/d/1I_oc-N4n3j0QgLStoaXcqaMDgceyYYI1aimcn2udF1s/edit?gid=265742791#gid=265742791 Support the Pod!

I love wireless (wi-fi) communications. In fact, I did my PhD around the propagation of radio waves using Maxwell's equations. The beauty and perfection of radio waves will never leave me. The first thing you often learn about wifi is how the frequency of the wave relates to its wavelength (lambda=speed of light divided by the frequency) and how dipole antennas have to be around half a wavelength long. For AM, there are long antennas (such as, with the ones that wrap copper around a core) or can be short ones (like the dipole antenna on your wireless router). Much of the magic happens around 2.4GHz.. and which gives a wavelength of 12.5cm, and where if you measure the dipole antenna, it will be around 6cm high. Once you learn about this, you are often hooked on the wonderment of radio waves. It has solid mathematics, but is also a black art (ask any RF engineer, and they will tell you this)! Overall, too, wi-fi has freed us from those pesky twisted pair of cables and those troublesome RJ45 and RJ11 connectors. And, at the core of wifi, is signal strength, and where the stronger the signal, the more chance we have of creating a good network connection. For this, with most IEEE 802.11x standards, the bandwidth that you can use often relates to the signal strength that you have — so the further away you are from the transmitter, the more likely it is that you will have a lower bandwidth capacity. I, too, love all the different antenna shapes and designs and try to imagine how they spread their signals. But those pesky metal things get in the way and can bounce signals in other directions (which is sometimes a good thing, of course), and the other materials, such as concrete, will reduce the signal strength. For all the maths of Maxwell's equations, a lot comes down to measurements and simulations. At home, you might have a MIMO (Multiple In, Multiple Out) transmitter, and which bounces signals of objects and transmits on multiple channels. This might give up to 540Mbps. But, the further you go away from this, the bandwidth reduces until it will drop to nearer 11 Mbps. And, so RSSI (Receiver Signal Strength Indicator) is an important measurement as it defines how good your signal strength is — at a point in time. This will obviously vary as you move and as other things move around you. But, at the other end, if you have too much signal strength, you can breach health and safety regulations. Currently, this is around 100mW, and you need to have a good reason if you need higher power levels than this, as too much radio power — especially around 2.4GHz — might affect someone's health. So, let's talk about that troublesome (and powerful) unit called dBm, and where it is all about adding and subtracting, and not those difficult maths operations of multiplying and dividing. Believe in John Napier's logs to help our wifi systems:

Ever wondered about the intricacies of RJ45 mod plugs and the differences between stranded and non-stranded PoE cables? You're in luck! Join us for an enlightening conversation with Blake Tally, Vice President and Partner, at Go Simply Connect, who shares his vast knowledge and over 10 years of experience in the connector side of the industry, as well as insights from his partners in the cable side of the business.In this episode, we discuss the significance of the UL94VO rating for RJ45 modular plugs, particularly for plenum rated products used in air handling spaces. We also dive into the differences between mod plugs designed for horizontal cabling and patch cables, and the crucial role that contact design plays in their effectiveness. Additionally, we touch on the importance of collaboration between cable companies and connector companies in producing successful products, and how manufacturers have developed crimp products and tools to a TIA-rated standard to help reduce the number of connectors needed.Finally, we explore the necessity of using the right tools for the job, especially when it comes to RJ45 mod plugs. Discover the TIA standards for RJ45 mod plugs, the value of having the right tool, and the impact it has on the quality of the products. We also discuss the pros and cons of using a more affordable crimp frame for DIY projects versus a more professional grade product, and the importance of maintaining the tools and changing the blade of a pass-through crimp frame to get the most out of it.  Don't miss this informative episode with Blake Tally and gain valuable insights into the world of RJ45 mod plugs!Support the showKnowledge is power!

UGREEN USB-C-Hubs: der Luxus ausreichender Anschlüsse für "klein" mit fünf und "groß" mit sieben zusätzlichen Anschlüssen für das Notebook, Chromebook und Apple!Es gibt, wenn man mit seinem "mobilen Rechner" unterwegs ist, genau zwei essenzielle Dinge, die in den wirklich wichtigen Momenten nie da sind: Das Netzteil und ausreichend Anschlüsse für all die Geräte, die man jetzt sofort und natürlich gleichzeitig benötigt. Kein Wunder, haben die Hersteller zum einen aufgrund Gewicht und Maßen, auf der anderen Seite aufgrund von Kosten und damit Gewinn reduziert, was einfach als überflüssig empfunden wird. Und in Teilen auch absichtlich dem Zubehörmarkt überlassen wird. UGREEN hat sich ebenfalls des Themas angenommen und bietet zwei multifunktionale Docks an, um fehlenden Anschlüssen Herr zu werden, mit wahlweise fünf oder sieben "Erweiterungen". UGREEN USB-C-Docks für ein Mehr an Anschlüsse / Bild-/Quelle: privat Dass ich ein großer Fan von Googles Chromebooks bin, muss ich nicht erwähnen. Mein Erstes war weiß und Vollplastik, hat dafür aber jahrelang unfassbar viel mitgemacht. Und es war auch ein Gerät, dass noch einen vollwertigen Ethernet-Anschluss mitbrachte. Das Nachfolgemodell war teurer, ist in aufpoliertes Metallgedöhns verpackt und musste bereits, obwohl in Garantie, teuer repariert werden. Weil das Gehäuse verspricht, was es nicht hält - und was für ein tragbares Gerät schlichtweg nur als Mogelpackung tituliert werden kann. Und ja: kein Ethernet mehr an Board. Ich glaube, vorstehendes Szenario kennt jeder, der mit seinem Laptop, egal mit welchem Betriebssystem oder auch Herstellerlogo, unterwegs ist. Dank USB-C wurden auch hier weitere Buchsen weggelassen. Dafür kann in den meisten Fällen beim Hersteller für teuer Geld ein "Miniadapter" erworben werden. Der überwiegend auf proprietäre Stecker passt und zumindest eine Art von Ethernet bietet und vornehmlich wahlweise einen HDMI-Anschluss oder einen weiteren USB-Kontakt in den Rechner ermöglicht. Blöd nur, und das trifft vor allem auf mich zu, dass diese Steckeradapter entweder nach Inbetriebnahme des neuen Geräts bombensicher für einen Handgriff auf Nimmerwiedersehen irgendwo verschwunden sind oder sich mit zielsicherer Genauigkeit nicht in dem aktuellen Transportrucksack befinden. Das war es mit Kabel-gebundenem Ethernet oder dem dringend benötigten USB-A-Anschluss für die externe Maus. Dem kann aber mit einer kleinen Investition praktische Abhilfe geleistet werden. Einzige Voraussetzung: ein freier USB-C-Anschluss am Gerät. Dafür bietet UGREEN zwei sogenannte "USB-C-Multifunction Docking Stations" an. UGREEN 5-in-1 - vier Anschlüsse in der Längsseite... / Bild-/Quelle: privat Die Kleine kostet bei meinem Lieblingsonlineversender aktuell knapp 40 Euro, die große 50 Euro, beide sind sofort lieferbar. Die günstige Variante bietet 5-in-1 mit einem USB-C-Anschluss mit PD 100 Watt, USB 3.0 mit 5 Gbps, HDMI mit 4K-Auflösung bei 60 Hertz und einen RJ45-1.000 Mbps-Ethernet-Stecker. Letzterer ist an der Stirnseite untergebracht, die anderen Stecken finden sich auf einer Längsseite. ...und Ethernet an der Stirnseite in einem soliden Gehäuse / Bild-/Quelle: privat Das reicht für eine Tagesreise mit dem Rechner locker aus, um alle Bedarfe an Stecker und Verbindungen problemlos zu ermöglichen. Durchdacht finde ich, dass man einen USB-C-Stecker opfern muss, der aber zugleich auf dem Dock wieder verfügbar gemacht wird, somit eine Mischung aus sinnvoller Nullrunde und Bereitstellung eines nötigen Anschlusses. Aber dann gibt es noch die Momente, an denen es nicht genug Anschlüsse sein können. Und wer mit Digitalkamera oder Drohne unterwegs ist, weiß, wie schwierig es ist, eine Micro- oder -SD-Karte auszulesen, wenn so gar nichts am Laptop vorhanden ist. 7-in-1-Dock in Einsatz - hier ist wirklich alles mit dran! / Bild-/Quelle: privat Auch hier hat UGREEN eine durchdachte Lösung in Form des 7-in-1-Docks. Aktueller Preis bei meinem Lieblingsonlineversender knapp 50 Euro. Für den Betrieb opfert man auch hier wieder einen USB-C-Anschluss, der allerdings durch das Dock wieder kompensiert wird, und der 100 Watt Ladeleistung mitbringt. Zusätzlich können SD- und Micro-SD-Karten (SD/TF-Slot) mit 104 MB/S ohne Adapter ausgelesen werden. Neben einem RJ45-Ethernet-Anschluss 1.000Mbps finden sich zwei USB-A-3.0-Anschlüsse mit 50Gbps und ein HDMI-Anschluss mit 4K- bei 60 Hertz Auflösung. Und, frisch nachgewogen: Das 7-in-1-Dock wiegt gute 60 Gramm, das 5-in-1 etwa 50 Gramm. Die Maße des 7er sind 12,5 cm lang, 3,5 cm breit und ungefähr 1,7 cm hoch, was natürlich dem Ethernet-Stecker zu verdanken ist. Beim 5er liegen die Maße mit knapp 12 cm Länge, gut 2,7 cm Breite und, auch wieder wegen der RJ45-Buchse bei gut 2,8 cm. Das Kabel des 5er-Docks ist gut 24 cm lang und versteckt sich in einem schwarzen Schrumpfschlauch, wohingegen das 7er-Dock gute 24,5 cm mitbringt und das Kabel für etwas härtere Einsätze mit Gewebe überzogen wurde (siehe vorstehendes und folgendes Bild für Kabeldetails). 5-in-1-Dock, wem es reicht, bekommt ein schickes abgerundetes Design / Bild-/Quelle: privat Wem fünf Anschlüsse reichen, bekommt ein kompaktes und mit den abgerundeten Ecken sehr stylisches Gerät. Ich gehe so weit, dass man das locker in der Hosentasche transportieren kann. Dafür bietet, und ich habe ja nicht zufällig das Beispiel mit der Drohne erwähnt, das 7-in-1-Dock für meine Mavic Air direkt den TF-Slot für die SD-Karte: raus aus der Drohne, rein in das Dock, schon auf dem Rechner und in Sekunden auf Youtube... Die Entscheidung, welches ihr braucht, kann ich euch nicht abnehmen. Ich unterstelle, dass es in erster Linie um die fehlenden oder wünschenswerten zusätzlichen Anschlussmöglichkeiten geht. Egal, ob fünf oder sieben, die technischen Daten sind hier für HDMI und USB identisch. Stellt sich also die Frage, ob der Aufpreis von zehn Euro euch einen Nutzen stiftet oder ob, zum Beispiel die SD-Karte für euch keinen Rolle spielt. In jedem Fall gebe ich den beiden Dock sowohl fürs Design als auch für die Handhabung und die Umsetzung als auch die technischen Daten zwei enthusiastisch erhobene Daumen! Solltet ihr auf der Suche sein oder eben gerne einen Anschluss mehr am Laptop haben, seht euch die beiden mal im Detail an! Bei den Links zu amazon für die zwei Docks handelt es sich um Affiliate Links. Wenn ihr über diese kauft, bekomme ich von amazon eine kleine Rückvergütung. Für euch ändert sich am Preis gar nichts!

Why the PBP? Lately I've been thinking a lot about power consumption when it comes to computing. Intuitively, I know that arm devices pull significantly less power than amd64 machines but I've never really tested this in the real world. So, some preliminary power consumption stats: big amd64 laptops (thinkpad x220 and t490) pull at most 65 watts small arm SOCs typically pull at most 15 watts most android phones pull at most 18 watts Pentium 4 pulls at most 250 watts These numbers are fairly easy to find: just look at the power supply for a MAXIMUM OUTPUT value or something similar. This is the point at which the power supply fails so we can safely assume this is the maximum power draw for any given computer. Of course, this is DC output and not AC output and anyone who knows anything about electricity knows that converting AC to DC is expensive but these values are useful as a general estimate. I wrote something similar about computer power consumption some time ago My goal in all of this was to find a self contained computer that runs UNIX, doesn't take much power, isn't a consumption rectangle (smartphone), and can be charged from both AC with a rectifier and stored DC without an inverter. Charging from existing stored power was probably the most novel consideration. Everything else is a given. A few obvious answers come to mind: Raspberry Pi 4 is not self contained and using a pitop in public is a good way to get the bomb squad called on you beaglebone black is good too but neither self contained nor popular enough for wide OS support Pinebook Pro is self contained and is supported by some of the operating systems I'd like to run The PBP is an obvious choice. It's an open hardware ARM laptop that can be charged via a barrel cable (AC->DC) or via USB-C. Charging from USB-C is a very useful feature because it means I can easily choose between charging from the mains where efficiency loss is acceptable and charging from a DC source where efficiency loss is unacceptable. The actual use case is "what computer can I run off of a old car battery or the alternator in my car without burning power with an inverter?". I'll revisit this use case in a later section. Initial notes I took these notes immediately upon opening the PBP. They remain unedited because I want to be honest on the first impressions. shipping I was worried about DHL dropping my package out of a plane. Or leaving it out in the rain. Or having one of the employees use it as a soccer ball. Or having the thing get stuck in customs. It ended up arriving safely and was packaged well. Two boxes within a padded envelope within another envelope. Surprising for DHL. hardware impressions Touchpad sucks and trackpad scrolling sucks (it's probably just KDE). Installing synaptics drivers allegedly fix this problem. keyboard is comfortable, clickly, full sized despite being a chicklet keyboard. I don't like that the and keys are backwards when compared to a thinkpad. I really like the thinkpad keyboard layout. Shift+enter seems to type the M character. My muscle memory for key chording is now broken. This appears to be a fundamental design flaw with KDE. Passively cooled, gets a bit warm. display is sharp (IPS) and almost too high resolution for my eyes (1920x1080 instead of 1366x768). I can fix this in software. enabling/disabling mic/wifi/camera through the keyboard is confusing and (seemingly) does not perform the "kill switch" via hotplugging like the Thinkpad X220's wifi kill switch. Charger comes with both US and EU prongs. software impressions it's manjaro :( it's KDE :( it comes with mpv :) bluez instead of bluetoothd :( firewalld instead of UFW WiFi dongle. To get around no RJ45 port, I use a USB->RJ45 adapter. I have an ASIX ax88772 dongle (UGREEN branded but I'm not sure that matters). Both of these dongles seem to work with every single operating system and hardware configuration I've tried them with. Arm is strange, so we must boot from an SD card (running any OS, in my case NetBSD) in order to burn an image to the internal storage. From a separate machine, the options passed to dd are important. $ wget https://cdn.netbsd.org/pub/NetBSD/NetBSD-9.3/evbarm-aarch64/binary/gzimg/arm64.img.gz $ wget http://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/x86_64/.9.0_2022Q2_pkgbuild/All/u-boot-pinebook-pro-2022.01nb1.tgz $ gunzip ./arm64.img $ tar xzf ./u-boot-pinebook-pro-2022.01nb1.tgz $ sudo umount /dev/sdx* $ sudo dd if=./arm64.img of=/dev/sdx status=progress conv=fsync bs=1M $ sudo sync $ sudo dd if=./u-boot-pinebook-pro-2022.01nb1/share/u-boot/pinebook-pro/rksd_loader.img of=/dev/sdx seek=64 conv=sync status=progress $ sudo sync $ sudo eject /dev/sdx And, to install NetBSD to the internal EMMC, the process is similar. NetBSD's version of dd varies slightly but the options passed are important. # ftp https://cdn.netbsd.org/pub/NetBSD/NetBSD-9.3/evbarm-aarch64/binary/gzimg/arm64.img.gz # gunzip ./arm64.img # dd if=./arm64.img of=/dev/rl0d conv=sync bs=1m # sync # PKG_PATH="http://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/aarch64/9.3/All/" pkg_add pkgin # pkgin install u-boot-pinebook-pro # sudo dd if=/usr/pkg/share/u-boot/pinebook-pro/rksd_loader.img of=/dev/rld0 seek=64 conv=sync # sync # reboot And, some more desktop centric things after booting from EMMC: # passwd # echo "postfix=NO" >> /etc/rc.conf # echo "xdm=YES" >> /etc/rc.conf Installing pkgin (and some packages): # PKG_PATH="https://cdn.NetBSD.org/pub/pkgsrc/packages/NetBSD/aarch64/9.3/All/" pkg_add pkgin # sed -i'' -e 's/9.0/9.3/g' /usr/pkg/etc/pkgin/repositories.conf # pkgin install vim git mozilla-rootcerts mozilla-rootcerts-openssl The rest is NetBSD specific and I've avoided getting into it here because it doesn't have anything to do with the PBP. Performance The PBP has 6 cores (2 fast, 4 slow) and 4gb ram. The cpu is fairly slow but entirely usable. On large procedural jobs like software compilation, it's painful. For concurrent jobs, it's mostly fine. Compiler performance As expected, the PBP is slower when it comes to compilation than a standard amd64 machine. Surprisingly enough, NetBSD was significantly slower than Manjaro. This is likely due to the Linux kernel knowing how to better handle multiple CPUs with varying speeds. sequential jobs I used plan9port because it's a fairly large but portable project. Compilation is largely sequential, invokes many standard shell utilities, and involves extra preprocessor steps to convert 9 C into something a standard UNIX compiler like GCC or Clang can compile. On a T490 - 8th gen Core i7 (4 cores, 8 threads, 4.8GHz, vPro for maximum thermal output): real 232.51 (~4 minutes) user 188.07 sys 65.01 On an X220 - 2nd gen Core i5 (2 cores, 4 threads, 2.6GHz, vPro for maximum thermal output): real 249.98 (~4 minutes) user 220.33 sys 65.52 On the PBP (2 2.0GHz cores + 4 1.5GHz cores, no CPU fan for maximum thermal output) (running stock Manjaro image): real 1355.27 (~22 minutes) user 1178.47 sys 347.71 On the PBP (2 2.0GHz cores + 4 1.5GHz cores, no CPU fan for maximum thermal output) (running NetBSD): real 3715.24 (~60 minutes) user 1946.84 sys 3435.29 concurrent jobs I used vim because it can be built in parallel without causing any issues. Same 8th gen Core i7 (make -j7): real 27.36 user 170.21 sys 11.30 Same 2nd gen Core i5 (make -j7, approaching the exponential decay of marginal returns on concurrent processing): real 77.07 user 292.46 sys 10.00 On the PBP (make -j7) (running stock Manjaro image): real 220.60 user 1145.40 sys 59.90 On the PBP (make -j7) (running NetBSD): real 319.30 user 1560.87 sys 255.33 Web browser testing Because the PBP has similar hardware specifications to the adware subsidized craptops sold by google, I thought it would be a good idea to compare web browser performance on these systems as well. I found a few web browser benchmark tests at browserbench.org. They're probably snakeoil but running JS tests is a good way to put a number on how performant $browser on $hardware is. Scores from the JetStream2 test JetStream 2.1 is a JavaScript and WebAssembly benchmark suite focused on the most advanced web applications. It rewards browsers that start up quickly, execute code quickly, and run smoothly. For more information, read the in-depth analysis. Bigger scores are better. Thinkpad T490 79.555 Thinkpad X220 39.983 PBP (manjaro) 19.148 I don't have an chromesumption book to test against, so all I can say is that the PBP is slower than a workhorse amd64 machine when it comes to interpreting javascript. Conclusion Did the PBP fulfill it's needs? The intended use case was "UNIX machine I can charge from an existing battery or alternator". This immediately invokes ideas of "why would I even need wifi support?" Ultimately, I ended up flashing a bad image to the SPI flash chip and I cannot get the system to boot (or even show signs of life). I have attempted to enter maskrom mode to re-flash the SPI but I am unsuccessful. There are a few other things I need to try. I'll update this if I ever get it functional again. I did not have the opportunity to test the machine in the exact environment I got it for but it was fun before I bricked it. Again, a place for updates. Who is the PBP for? HACKERS! Obviously, the types of people who are interested in pine64 devices and similar SBCs are already computer owners (if not computer hoarders). It's unlikely that the PBP will become my (or anyone's) primary computer but that doesn't mean that it's useless. The entire point of arm SBCs is to have fun so why not have fun? Just don't flash your SPI if you want it to work as expected. Some final thoughts on open hardware Oftentimes, before purchasing freedom centric hardware, I search for a few reviews so that I can set my expectations correctly. Oftentimes these reviews are very epidermal: they're not even skin deep. These reviewers are consumers producing reviews for a consumer audience, not hackers producing in-depth reviews for hacker audience. These types of reviews are frustrating for me but fundamental flaws seem to shine through the lack of thoroughness. I think that the general negative reviews on open hardware largely stem from unrealistic expectations. The community seems to over-hype many of these devices out of ignorance, stating that $freedomDevice is the $proprietaryAlternative killer, the end all be all device that will usher in the year of the Linux $deviceCategory. Oftentimes, it seems like the high expectations fall flat when confronted with the reality of open hardware: it's either way too expensive or way too experimental. It seems like many of these devices are lacking both developer time and users who are both enthusiastic and knowledgeable. Pitfalls of mobile UNIX include bad power management, difficulty hotplugging wireless chipsets, graphical interfaces attempting to cope with the fact that they don't have a physical keyboard, etc. There is still much work to be done. As for users, it seems that the most enthusiastic users always have the impression that $linuxDevice will have 1:1 feature parity with $proprietaryDevice. Maybe it's just that the loudest users are heard or that we only want to hear utopian dreams of a free software future. A prime example of this conflict between expectations and reality: Linux smartphones. It doesn't help when many linux smartphones over the years were advertised as a viable android competitor rather than anything other than what they actually were: an arm board attached to a touch screen and a modem. I oftentimes ask myself "what is open source worth?". How much money are you willing to throw at an idea you like? Surely, money thrown at an idea you like is being used better than money thrown at an idea you don't like. In many cases, it seems like open hardware devices are more expensive than their proprietary counterparts for a few reasons. The two largest reasons are small batch manufacturing and the fact that open hardware isn't subsidized by pre-installed adware (in the case of nearly every device that comes pre-loaded with proprietary software). What is open source worth? A few extra dollars, a few extra hours of configuration, a few extra papercuts, and a clean conscious knowing that I didn't pay for yet another windows license I will never use and will never get a refund for. Open source is worth investing in because the, albeit slow, improvements to open hardware and software have wider implications than just "buying a laptop with Linux pre installed". Future projects something with the raspi NetBSD in depth "why is my lightbulb running android?" and other Internet-Of-Terror ideas turning a router into a general purpose computing device (probably MIPS because where else am I going to find a MIPS CPU? Might as well do something novel instead of $arm-project-1209)

Hello everyone welcome to the show "Ethical Hacking" episode 83 today we are going to discuss about Securing WiFi devices.Wireless devices are much less secure than our traditional networks because their data streams are simply flying through the air,waiting to be gobbled up by some attacker sitting out there.When we talked about wire tapping in the last lesson,we talked about having to gain access to the network physically.Well, with a wireless network that challenge is eliminated because the network is literally floating in the airways.In this lesson we're going to discuss some of the basic vulnerabilities associated with wireless networks and how you can combat them.First, the administrative access on the wireless access point is a vulnerability.Usually these have default user names and passwords like admin, admin like we discussed before.And you have to make sure you secure them.Also, remote administration should be disabled on your wireless access points.Remote administration is something that allows you to connect over the internet and then make changes to your wireless access point.You don't need that.Instead you should turn it off and make sure that you're doing it locally inside your network only to minimize that risk.The second vulnerability we have to think about is the service set identifier,or the SSID.Back in network plus you learned that the SSID is what uniquely identifies the network and it acts as the name of the wireless access point that the clients are going to use to connect to it.For example, if you came by my offices,you would see that my network is the oh so hard name to guess of vijay.Anyone who sees that might think hey that might be vijay kumar's WiFi, right?Well, that's the SSIDs job.It sits there and it broadcasts out hey I'm here,I'm here, I'm vijay, I'm vijay I'm vijay Now, according to you should disable the broadcast.So clients have to already know the name of it prior to connecting to it.They say this is a way to slow down the bad guy from attacking your network.As an ethical hacker myself,I can tell you that it isn't really going to slow me down.If you aren't broadcasting openly,your clients are still sending the same wireless access point information and that SSID with every single communication they make.It takes me about five seconds to find out your SSID if you're not broadcasting.So by disabling it you're just making operations harder for yourself and you're not really gaining any security here.Now all of that said,if you're asked disable SSID broadcast is considered good security in the security and you should implement it.In the real world, it really doesn't matter that much.Now the next one we're going to talk about is rogue access points.Rogue access points are another vulnerability out there.A rogue access point is an unauthorized wireless access point or wireless router that somebody connected to your network and it's going to give access to your secure network.For example, if you walk around your office and somebody decided that they didn't want to plug into that RJ45 jack all the way in the back wall over there,so they put a wireless access point so they can access it throughout the whole room.That makes operations easy for them,but that wireless access point wasn't properly configured.This is going to extend your wired network into the wireless realm,and it can introduce it's own DHCP server and cause all sorts of other issues.To prevent this you should enable MAC filtering on the network,network access control and run a good IDS or IPS on your network that can detect or prevent these devices when they initially try to connect.

Dans cet épisode,  Il y a plusieurs choses à prendre en compte : le projet en lui-même : sur quoi s'appuie-t-il ? (un problème à résoudre) sur qui s'appuie-t-il ? (les enseignants, les élèves, les parents, toi uniquement ?) le côté technique : quelles sont les infrastructures ? De quoi je parle là ? de switches, de serveurs, de fibre, de prises RJ45... le côté financier : comment le financer pour qu'il perdure ?

Ultrasonic sensors have many potent features, making them an invaluable tool for the automation professional. They securely detect objects of any color, have significant sensing range, and securely detect objects largely independent of surface structure. Combining ultrasonic detection with IO-Link communication makes using the sensor’s capabilities a breeze. Detecting targets in the presence of interfering objects in the detection field, further enhance the capabilities of these all-rounders. Cordsets and connectors are critical components for the reliable operation of automated machinery, material handling systems, robots, and mobile equipment. In today’s episode, we focus on some recent enhancements to this frequently overlooked class of products and discuss rugged Ethernet cables as well as tough, overmolded mobile equipment connectors.

FreeBSD internship learnings, exciting developments coming to FreeBSD, running FreeNAS on DigitalOcean, Network Manager control for OpenBSD, OpenZFS User Conference Videos are here and batch editing files with ed. Headlines What I learned during my FreeBSD intership Hi, my name is Mitchell Horne. I am a computer engineering student at the University of Waterloo, currently in my third year of studies, and fortunate to have been one of the FreeBSD Foundation’s co-op students this past term (January to April). During this time I worked under Ed Maste, in the Foundation’s small Kitchener office, along with another co-op student Arshan Khanifar. My term has now come to an end, and so I’d like to share a little bit about my experience as a newcomer to FreeBSD and open-source development. I’ll begin with some quick background — and a small admission of guilt. I have been an open-source user for a large part of my life. When I was a teenager I started playing around with Linux, which opened my eyes to the wider world of free software. Other than some small contributions to GNOME, my experience has been mostly as an end user; however, the value of these projects and the open-source philosophy was not lost on me, and is most of what motivated my interest in this position. Before beginning this term I had no personal experience with any of the BSDs, although I knew of their existence and was extremely excited to receive the position. I knew it would be a great opportunity for growth, but I must confess that my naivety about FreeBSD caused me to make the silent assumption that this would be a form of compromise — a stepping stone that would eventually allow me to work on open-source projects that are somehow “greater” or more “legitimate”. After four months spent immersed in this project I have learned how it operates, witnessed its community, and learned about its history. I am happy to admit that I was completely mistaken. Saying it now seems obvious, but FreeBSD is a project with its own distinct uses, goals, and identity. For many there may exist no greater opportunity than to work on FreeBSD full time, and with what I know now I would have a hard time coming up with a project that is more “legitimate”. What I Liked In all cases, the work I submitted this term was reviewed by no less than two people before being committed. The feedback and criticism I received was always both constructive and to the point, and it commented on everything from high-level ideas to small style issues. I appreciate having these thorough reviews in place, since I believe it ultimately encourages people to accept only their best work. It is indicative of the high quality that already exists within every aspect of this project, and this commitment to quality is something that should continue to be honored as a core value. As I’ve discovered in some of my previous work terms, it is all too easy cut corners in the name of a deadline or changing priorities, but the fact that FreeBSD doesn’t need to make these types of compromises is a testament to the power of free software. It’s a small thing, but the quality and completeness of the FreeBSD documentation was hugely helpful throughout my term. Everything you might need to know about utilities, library functions, the kernel, and more can be found in a man page; and the handbook is a great resource as both an introduction to the operating system and a reference. I only wish I had taken some time earlier in the term to explore the different documents more thoroughly, as they cover a wide range of interesting and useful topics. The effort people put into writing and maintaining FreeBSD’s documentation is easy to overlook, but its value cannot be overstated. What I Learned Although there was a lot I enjoyed, there were certainly many struggles I faced throughout the term, and lessons to be learned from them. I expect that some of issues I faced may be specific to FreeBSD, while others may be common to open-source projects in general. I don’t have enough experience to speculate on which is which, so I will leave this to the reader. The first lesson can be summed up simply: you have to advocate for your own work. FreeBSD is made up in large part by volunteer efforts, and in many cases there is more work to go around than people available to do it. A consequence of this is that there will not be anybody there to check up on you. Even in my position where I actually had a direct supervisor, Ed often had his plate full with so many other things that the responsibility to find someone to look at my work fell to me. Admittedly, a couple of smaller changes I worked on got left behind or stuck in review simply because there wasn’t a clear person/place to reach out to. I think this is both a barrier of entry to FreeBSD and a mental hurdle that I needed to get over. If there’s a change you want to see included or reviewed, then you may have to be the one to push for it, and there’s nothing wrong with that. Perhaps this process should be easier for newcomers or infrequent contributors (the disconnect between Bugzilla and Phabricator definitely leaves a lot to be desired), but we also have to be aware that this simply isn’t the reality right now. Getting your work looked at may require a little bit more self-motivation, but I’d argue that there are much worse problems a project like FreeBSD could have than this. I understand this a lot better now, but it is still something I struggle with. I’m not naturally the type of person who easily connects with others or asks for help, so I see this as an area for future growth rather than simply a struggle I encountered and overcame over the course of this work term. Certainly it is an important skill to understand the value of your own work, and equally important is the ability to communicate that value to others. I also learned the importance of starting small. My first week or two on the job mainly involved getting set up and comfortable with the workflow. After this initial stage, I began exploring the project and found myself overwhelmed by its scale. With so many possible areas to investigate, and so much work happening at once, I felt quite lost on where to begin. Many of the potential projects I found were too far beyond my experience level, and most small bugs were picked up and fixed quickly by more experienced contributors before I could even get to them. It’s easy to make the mistake that FreeBSD is made up solely of a few rock-star committers that do everything. This is how it appears at face-value, as reading through commits, bug reports, and mailing lists yields a few of the same names over and over. The reality is that just as important are the hundreds of users and infrequent contributors who take the time to submit bug reports, patches, or feedback. Even though there are some people who would fall under the umbrella of a rock-star committer, they didn’t get there overnight. Rather, they have built their skills and knowledge through many years of involvement in FreeBSD and similar projects. As a student coming into this project and having high expectations of myself, it was easy to set the bar too high by comparing myself against those big committers, and feel that my work was insignificant, inadequate, and simply too infrequent. In reality, there is no reason I should have felt this way. In a way, this comparison is disrespectful to those who have reached this level, as it took them a long time to get there, and it’s a humbling reminder that any skill worth learning requires time, patience, and dedication. It is easy to focus on an end product and simply wish to be there, but in order to be truly successful one must start small, and find satisfaction in the struggle of learning something new. I take pride in the many small successes I’ve had throughout my term here, and appreciate the fact that my journey into FreeBSD and open-source software is only just beginning. Closing Thoughts I would like to close with some brief thank-you’s. First, to everyone at the Foundation for being so helpful, and allowing this position to exist in the first place. I am extremely grateful to have been given this unique opportunity to learn about and give back to the open-source world. I’d also like to thank my office mates; Ed: for being an excellent mentor, who offered an endless wealth of knowledge and willingness to share it. My classmate and fellow intern Arshan: for giving me a sense of camaraderie and the comforting reminder that at many moments he was as lost as I was. Finally, a quick thanks to everyone else I crossed paths with who offered reviews and advice. I appreciate your help and look forward to working with you all further. I am walking away from this co-op with a much greater appreciation for this project, and have made it a goal to remain involved in some capacity. I feel that I’ve gained a little bit of a wider perspective on my place in the software world, something I never really got from my previous co-ops. Whether it ends up being just a stepping stone, or the beginning of much larger involvement, I thoroughly enjoyed my time here.

News Roundup Network Manager Control for OpenBSD (Updated) Generalities I just remind the scope of this small tool: allow you to pre-define several cable or wifi connections let nmctl to connect automatically to the first available one allow you to easily switch from one network connection to an other one create openbox dynamic menus Enhancements in this version This is my second development version: 0.2. I've added performed several changes in the code: code style cleanup, to better match the python recommendations adapt the tool to allow to connect to an Open-wifi having blancs in the name. This happens in some hotels implement a loop as work-around concerning the arp table issue. The source code is still on the git of Sourceforge.net. You can see the files here And you can download the last version here Feedbacks after few months I'm using this script on my OpenBSD laptop since about 5 months. In my case, I'm mainly using the openbox menus and the --restart option. The Openbox menus The openbox menus are working fine. As explain in my previous blog, I just have to create 2 entries in my openbox's menu.xml file, and all the rest comes automatically from nmctl itself thanks to the --list and --scan options. I've not changed this part of nmctl since it works as expected (for me :-) ). The --restart option Because I'm very lazy, and because OpenBSD is very simple to use, I've added the command "nmctl --restart" in the /etc/apm/resume script. Thanks to apmd, this script will be used each time I'm opening the lid of my laptop. In other words, each time I'll opening my laptop, nmctl will search the optimum network connection for me. But I had several issues in this scenario. Most of the problems were linked to the arp table issues. Indeed, in some circumstances, my proxy IP address was associated to the cable interface instead of the wifi interface or vice-versa. As consequence I'm not able to connect to the proxy, thus not able to connect to internet. So the ping to google (final test nmctl perform) is failing. Knowing that anyhow, I'm doing a full arp cleanup, it's not clear for me from where this problem come from. To solve this situation I've implemented a "retry" concept. In other words, before testing an another possible network connection (as listed in my /etc/nmctl.conf file), the script try 3x the current connection's parameters. If you want to reduce or increase this figures, you can do it via the --retry parameter. Results of my expertise with this small tool Where ever I'm located, my laptop is now connecting automatically to the wifi / cable connection previously identified for this location. Currently I have 3 places where I have Wifi credentials and 2 offices places where I just have to plug the network cable. Since the /etc/apm/resume scripts is triggered when I open the lid of the laptop, I just have to make sure that I plug the RJ45 before opening the laptop. For the rest, I do not have to type any commands, OpenBSD do all what is needed ;-). I hotels or restaurants, I can just connect to the Open Wifi thanks to the openbox menu created by "nmctl --scan". Next steps Documentation The tool is missing lot of documentation. I appreciate OpenBSD for his great documentation, so I have to do the same. I plan to write a README and a man page at first instances. But since my laziness, I will do it as soon as I see some interest for this tool from other persons. Tests I now have to travel and see how to see the script react on the different situations. Interested persons are welcome to share with me the outcome of their tests. I'm curious how it work. OpenBSD 6.3 on EdgeRouter Lite simple upgrade method TL;DR OpenBSD 6.3 oceton upgrade instructions may not factor that your ERL is running from the USB key they want wiped with the miniroot63.fs image loaded on. Place the bsd.rd for OpenBSD 6.3 on the sd0i slice used by U-Boot for the kernel, and then edit the boot command to run it. a tiny upgrade The OpenBSD documentation is comprehensive, but there might be rough corners around what are probably edge cases in their user base. People running EdgeRouter Lite hardware for example, who are looking to upgrade from 6.2 to 6.3. The documentation, which gave us everything we needed last time, left me with some questions about how to upgrade. In INSTALL.octeon, the Upgrading section does mention: The best solution, whenever possible, is to backup your data and reinstall from scratch I had to check if that directive existed in the documentation for other architectures. I wondered if oceton users were getting singled out. We were not. Just simplicity and pragmatism. Reading on: To upgrade OpenBSD 6.3 from a previous version, start with the general instructions in the section "Installing OpenBSD". But that section requires us to boot off of TFTP or NFS. Which I don’t want to do right now. Could also use a USB stick with the miniroot63.fs installed on it. But as the ERL only has a single USB port, we would have to remove the USB stick with the current install on it. Once we get to the Install or Upgrade prompt, there would be nothing to upgrade. Well, I guess I could use a USB hub. But the ERL’s USB port is inside the case. With all the screws in. And the tools are neatly put away. And I’d have to pull the USB hub from behind a workstation. And it’s two am. And I cleaned up the cabling in the lab this past weekend. Looks nice for once. So I don’t want to futz around with all that. There must be an almost imperceptibly easier way of doing this than setting up a TFTP server or NFS share in five minutes… Right? iXsystems Boise Technology Show 2018 Recap OpenZFS User Conference Slides & Videos Thank you ZFS ZSTD Compression Pool Layout Considerations ZFS Releases Helping Developers Help You ZFS and MySQL on Linux Micron OSNEXUS ZFS at Six Feet Up Flexible Disk Use with OpenZFS Batch editing files with ed what’s ‘ed’? ed is this sort of terrifying text editor. A typical interaction with ed for me in the past has gone something like this: $ ed help ? h ? asdfasdfasdfsadf ? Basically if you do something wrong, ed will just print out a single, unhelpful, ?. So I’d basically dismissed ed as an old arcane Unix tool that had no practical use today. vi is a successor to ed, except with a visual interface instead of this ? surprise: Ed is actually sort of cool and fun So if Ed is a terrifying thing that only prints ? at you, why am I writing a blog post about it? WELL!!!! On April 1 this year, Michael W Lucas published a new short book called Ed Mastery. I like his writing, and even though it was sort of an april fool’s joke, it was ALSO a legitimate actual real book, and so I bought it and read it to see if his claims that Ed is actually interesting were true. And it was so cool!!!! I found out: how to get Ed to give you better error messages than just ? that the name of the grep command comes from ed syntax (g/re/p) the basics of how to navigate and edit files using ed All of that was a cool Unix history lesson, but did not make me want to actually use Ed in real life. But!!! The other neat thing about Ed (that did make me want to use it!) is that any Ed session corresponds to a script that you can replay! So if I know Ed, then I can use Ed basically as a way to easily apply vim-macro-like programs to my files.

Foundations of Amateur Radio Previously I've talked about leaving your shack and setting up your station in a different location. I have my car configured as a mobile shack of sorts, that is, it's got a radio, an antenna mount and wiring to manage the location of the speaker, the head-unit and the microphone. This weekend I'm planning to do a contest and it's been a while since I operated my radio from my car. I've been advocating that you should do some preparation before actually going and doing your thing, so during the week at lunch time I had a look around on the map and picked a spot that I'd like to operate the contest from this weekend. I drove to the location and pretended to set-up my station, actually, I did set it up. Tuned to the actual frequency, configured my tuner, found out that the tuning range for my antenna isn't ideal for 80m, not that this was a surprise. I'm using a so-called multi-tap antenna and the tuning range is somewhat dependent on factors such as the little metal spike that sits on top and where on my car it's mounted. In these situations I've heard other amateurs make statements that it's obvious because it's a compromise antenna. You won't actually hear me say that, since all antennas are a compromise, but then you already knew that. More surprising was the configuration of where I put the head-unit in my car. In the past I've used a modified mobile phone suction mount but sun and age have conspired into making that unsuitable, so I learned that I'd have to figure something out before my contest. Another surprise was that the microphone lead, which connects to a so-called separation cable, think Ethernet cable with RJ45 and joiners which connects back to the radio, had a little broken Ethernet doohicky (it's called the locking latch), which means that while you can push the connector in place, it doesn't stay. I also remembered that this contest was going to be in the dark, so I went looking for my LCD headlamp and it wasn't where I left it. So, now, several days later, after making my to-fix list, I actually managed to cobble together a few spare minutes and address most of my issues. The only one remaining is where to find the Allen Key for an 80m vertical antenna that I'm also bringing, just in case. The point of all this is that normally if you'd asked me if I was ready for my contest this weekend my immediate answer would have been: "Sure". I'm glad I followed the advise I have learned from the many mistakes I've made in the past by actually checking and because I actually went on-site I also managed to check out the local HF environment which means that come contest time I won't have a surprise that could have been managed by better preparation. No doubt there will be more to learn, but that's for after the contest. Perhaps next week. What do you do in preparation for an outing? I'm Onno VK6FLAB

Comencem a dues veus amb una bateria de petites notícies que us resumim aquí: - Sushi Go! guanya el Premi Ibertoy 2015 al millor joc de taula i societat - Devir publicarà Cacao, un altre joc de l'australià Phil Walker-Harding - Torna el Tast de Jocs del CAE aquest cap de setmana a Manresa - Torneig de Catan a l'Ateneu Candela de Terrassa el proper 28 de març - Assistirem convidats al #JuevesBlogger de la fira Ibertoy 2015 Si hi ha una persona a Catalunya que hagi apostat fort i amb regularitat per donar visibilitat als jocs de taula, aquesta persona és Oriol Comas. Als anys que porto a l'afició he vist com, any rere any, els projectes promoguts per aquest frontman (l'apel·latiu implica també un lògic reconeixement als equips humans que s'hi han associat) creixien quantitativament i qualitativa. La fira JugarXJugar de Granollers amb el seu històric concurs de creació de jocs o el magnífic festival DAU Barcelona, que només en tres edicions ja s'ha convertit en el pal de paller dels festivals a nivell estatal, són els seus millors avals. Avui parlem amb ell i com sempre aprenem molt, l'eix de l'entrevista és la presència catalana al passat Festival International des Jeux de Cannes. Per acabar-ho de lligar tot, passem d'un comissari a una comissària... de festivals. Així ens permetem recuperar l'àudio de Nadine Seul al passat DAU Barcelona on (amb un gran castellà) ens va explicar pam a pam el festival de Cannes i va deixar anar, entre dada i dada, un full de ruta més que interessant per a la nostra afició. Tot plegat esdevé un bon document que evidencia la bona salut del sector del joc de taula modern i dels festivals que el defensen (més que com a producte) com a producte sociocultural. No hem adjuntat cap secció perquè hem considerat que en centrar-se l'episodi en Cannes i DAU (majoritàriament), potser hauria quedat una mica off-topic... però no patiu, en breu tindrem més poti-poti lúdic!
