Tech News Weekly Episode 392 Show Notes This week on Tech News Weekly, Mikah Sargent and Jennifer Pattison Tuohy talk cybersecurity vulnerabilities with over 40,000 exposed internet cameras, Wyze's new security features following past breaches, a study on youth mental health and addictive tech use, and the launch of Trump Mobile's new phone and cellular plan. • 40,000 Exposed Internet Cameras: A cybersecurity investigation by BitSight reveals that over 40,000 internet-connected cameras are accessible to anyone with a browser and IP address, many of which use default passwords or lack basic security features. • Wyze Introduces "Verified View" Security Feature: Following previous incidents where users could see other people's camera streams due to cloud failures, Wyze launched a new security feature that stamps user metadata onto footage for an additional layer of verification to access photos and videos. • Study Challenges Screen Time Assumptions for Youth Mental Health: A major JAMA study tracking over 4,000 kids from ages 10-14 found no direct link between screen time duration and suicidal behavior, but instead identified addictive usage patterns as the real culprit. • The Launch of Trump Mobile: The new "47 Plan" offers 20GB of data for $47.45/month, along with a $499 phone claimed to be "made in America," though tech experts question both the value proposition and manufacturing claims.

Summary:If you're anything like the photographers in my community, you're probably feeling tired of comparing your level of success to other photographers in your market. So many of my current clients have mentioned that they have been feeling like they aren't “measuring up” to where they want to be in their business. And it's left them feeling defeated and a little bit frustrated.They've been hyper focused on hitting certain income goals and they're feeling really burned out from it. And so one thing we've been focusing on is helping them create a new definition of success so they can take BIG action that actually creates more income and results.We're opening up this conversation so that you can start feeling more confident and allow you to create goals that actually mean something to you and make a bigger impact inside your business.My goal for you leaving this episode is to have a plan that will allow you to spend your entire summer celebrating the heck out of your business because you have complete clarity around what success looks like for you – and you're making moves and feeling the momentum that is going to get you there.Let's dive in!Loved the episode?

And if you know me, you KNOW that I'm all about taking inspired action and creating momentum in a sustainable way – so grab your notebook and a pen and get ready to take some notes during the episode.Let's dive in!Loved the episode?

In this episode, Chris talks to Derek Dicker, CEO at Nyriad about the UltraIO storage array. Nyriad has developed a new storage architecture using GPUs that accelerate the calculations needed to store data using erasure coding. This enables UltraIO to implement system-wide data protection using erasure coding at the block level. In contrast to most storage vendors in the market today, the UltraIO platform uses hard disk drives, with a GPU to process data ingested by the system, while data is presented back through the CPU route. This dual processor architecture enables Nyriad to deliver a product with 20GB/s of throughput, scale to multiple petabytes of capacity and provide dynamic data protection defined by the customer. Nyriad sees UltraIO being used across four industries - HPC, Media & Entertainment, Backup and Recovery, and Active Archive. Essentially the solution excels at handling large volumes of unstructured data that needs high throughput processing.

Of 300 000 public responses to proposed regulations, Department of Health officials read just 132 – and completely ignored the fact that 97% of the submissions were against them. The regulations propose indefinitely imposing mask-wearing; need to provide vaccination certificates for access into SA and large gatherings; and the capping of audiences in public facilities to 50% of capacity. In addition, now public emails by DDG Dr Nicholas Crisp confirm official disdain of the consulting cornerstone of the SA democratic process. In this interview with BizNews founder Alec Hogg, Sakeliga's Russell Lamberti and Tian Alberts unpack disclosures laid bare after the court forced the DOH to hand over 20GB of data files to its court opponent.

Papers we love: ARC by Bryan Cantrill, SSD caching adventures with ZFS, OpenBSD full disk encryption setup, and a Perl5 Slack Syslog BSD daemon. This episode was brought to you by Headlines Papers We Love: ARC: A Self-Tuning, Low Overhead Replacement Cache (https://www.youtube.com/watch?v=F8sZRBdmqc0&feature=youtu.be) Ever wondered how the ZFS ARC (Adaptive Replacement Cache) works? How about if Bryan Cantrill presented the original paper on its design? Today is that day. Slides (https://www.slideshare.net/bcantrill/papers-we-love-arc-after-dark) It starts by looking back at a fundamental paper from the 40s where the architecture of general-purpose computers are first laid out The main is the description of memory hierarchies, where you have a small amount of very fast memory, then the next level is slower but larger, and on and on. As we look at the various L1, L2, and L3 caches on a CPU, then RAM, then flash, then spinning disks, this still holds true today. The paper then does a survey of the existing caching policies and tries to explain the issues with each. This includes ‘MIN', which is the theoretically optimal policy, which requires future knowledge, but is useful for setting the upper bound, what is the best we could possibly do. The paper ends up showing that the ARC can end up being better than manually trying to pick the best number for the workload, because it adapts as the workload changes At about 1:25 into the video, Bryan start talking about the practical implementation of the ARC in ZFS, and some challenges they have run into recently at Joyent. A great discussion about some of the problems when ZFS needs to shrink the ARC. Not all of it applies 1:1 to FreeBSD because the kernel and the kmem implementation are different in a number of ways There were some interesting questions asked at the end as well *** How do I use man pages to learn how to use commands? (https://unix.stackexchange.com/a/193837) nwildner on StackExchange has a very thorough answer to the question how to interpret man pages to understand complicated commands (xargs in this case, but not specifically). Have in mind what you want to do. When doing your research about xargs you did it for a purpose, right? You had a specific need that was reading standard output and executing commands based on that output. But, when I don't know which command I want? Use man -k or apropos (they are equivalent). If I don't know how to find a file: man -k file | grep search. Read the descriptions and find one that will better fit your needs. Apropos works with regular expressions by default, (man apropos, read the description and find out what -r does), and on this example I'm looking for every manpage where the description starts with "report". Always read the DESCRIPTION before starting Take a time and read the description. By just reading the description of the xargs command we will learn that: xargs reads from STDIN and executes the command needed. This also means that you will need to have some knowledge of how standard input works, and how to manipulate it through pipes to chain commands The default behavior is to act like /bin/echo. This gives you a little tip that if you need to chain more than one xargs, you don't need to use echo to print. We have also learned that unix filenames can contain blank and newlines, that this could be a problem and the argument -0 is a way to prevent things explode by using null character separators. The description warns you that the command being used as input needs to support this feature too, and that GNU find support it. Great. We use a lot of find with xargs. xargs will stop if exit status 255 is reached. Some descriptions are very short and that is generally because the software works on a very simple way. Don't even think of skipping this part of the manpage ;) Other things to pay attention... You know that you can search for files using find. There is a ton of options and if you only look at the SYNOPSIS, you will get overwhelmed by those. It's just the tip of the iceberg. Excluding NAME, SYNOPSIS, and DESCRIPTION, you will have the following sections: When this method will not work so well... + Tips that apply to all commands Some options, mnemonics and "syntax style" travel through all commands making you buy some time by not having to open the manpage at all. Those are learned by practice and the most common are: Generally, -v means verbose. -vvv is a variation "very very verbose" on some software. Following the POSIX standard, generally one dash arguments can be stacked. Example: tar -xzvf, cp -Rv. Generally -R and/or -r means recursive. Almost all commands have a brief help with the --help option. --version shows the version of a software. -p, on copy or move utilities means "preserve permissions". -y means YES, or "proceed without confirmation" in most cases. Default values of commands. At the pager chunk of this answer, we saw that less -is is the pager of man. The default behavior of commands are not always shown at a separated section on manpages, or at the section that is most top placed. You will have to read the options to find out defaults, or if you are lucky, typing /pager will lead you to that info. This also requires you to know the concept of the pager(software that scrolls the manpage), and this is a thing you will only acquire after reading lots of manpages. And what about the SYNOPSIS syntax? After getting all the information needed to execute the command, you can combine options, option-arguments and operands inline to make your job done. Overview of concepts: Options are the switches that dictates a command behavior. "Do this" "don't do this" or "act this way". Often called switches. Check out the full answer and see if it helps you better grasp the meaning of a man page and thus the command. *** My adventure into SSD caching with ZFS (Home NAS) (https://robertputt.co.uk/my-adventure-into-ssd-caching-with-zfs-home-nas.html) Robert Putt as written about his adventure using SSDs for caching with ZFS on his home NAS. Recently I decided to throw away my old defunct 2009 MacBook Pro which was rotting in my cupboard and I decided to retrieve the only useful part before doing so, the 80GB Intel SSD I had installed a few years earlier. Initially I thought about simply adding it to my desktop as a bit of extra space but in 2017 80GB really wasn't worth it and then I had a brainwave… Lets see if we can squeeze some additional performance out of my HP Microserver Gen8 NAS running ZFS by installing it as a cache disk. I installed the SSD to the cdrom tray of the Microserver using a floppy disk power to SATA power converter and a SATA cable, unfortunately it seems the CD ROM SATA port on the motherboard is only a 3gbps port although this didn't matter so much as it was an older 3gbps SSD anyway. Next I booted up the machine and to my suprise the disk was not found in my FreeBSD install, then I realised that the SATA port for the CD drive is actually provided by the RAID controller, so I rebooted into intelligent provisioning and added an additional RAID0 array with just the 1 disk to act as my cache, in fact all of the disks in this machine are individual RAID0 arrays so it looks like just a bunch of disks (JBOD) as ZFS offers additional functionality over normal RAID (mainly scrubbing, deduplication and compression). Configuration Lets have a look at the zpool before adding the cache drive to make sure there are no errors or uglyness: Now lets prep the drive for use in the zpool using gpart. I want to split the SSD into two seperate partitions, one for L2ARC (read caching) and one for ZIL (write caching). I have decided to split the disk into 20GB for ZIL and 50GB for L2ARC. Be warned using 1 SSD like this is considered unsafe because it is a single point of failure in terms of delayed writes (a redundant configuration with 2 SSDs would be more appropriate) and the heavy write cycles on the SSD from the ZIL is likely to kill it over time. Now it's time to see if adding the cache has made much of a difference. I suspect not as my Home NAS sucks, it is a HP Microserver Gen8 with the crappy Celeron CPU and only 4GB RAM, anyway, lets test it and find out. First off lets throw fio at the mount point for this zpool and see what happens both with the ZIL and L2ARC enabled and disabled. Observations Ok, so the initial result is a little dissapointing, but hardly unexpected, my NAS sucks and there are lots of bottle necks, CPU, memory and the fact only 2 of the SATA ports are 6gbps. There is no real difference performance wise in comparison between the results, the IOPS, bandwidth and latency appear very similar. However lets bare in mind fio is a pretty hardcore disk benchmark utility, how about some real world use cases? Next I decided to test a few typical file transactions that this NAS is used for, Samba shares to my workstation. For the first test I wanted to test reading a 3GB file over the network with both the cache enabled and disabled, I would run this multiple times to ensure the data is hot in the L2ARC and to ensure the test is somewhat repeatable, the network itself is an uncongested 1gbit link and I am copying onto the secondary SSD in my workstation. The dataset for these tests has compression and deduplication disabled. Samba Read Test Not bad once the data becomes hot in the L2ARC cache reads appear to gain a decent advantage compared to reading from the disk directly. How does it perform when writing the same file back accross the network using the ZIL vs no ZIL. Samba Write Test Another good result in the real world test, this certainately helps the write transfer speed however I do wonder what would happen if you filled the ZIL transferring a very large file, however this is unlikely with my use case as I typically only deal with a couple of files of several hundred megabytes at any given time so a 20GB ZIL should suit me reasonably well. Is ZIL and L2ARC worth it? I would imagine with a big beefy ZFS server running in a company somewhere with a large disk pool and lots of users with multiple enterprise level SSD ZIL and L2ARC would be well worth the investment, however at home I am not so sure. Yes I did see an increase in read speeds with cached data and a general increase in write speeds however it is use case dependant. In my use case I rarely access the same file frequently, my NAS primarily serves as a backup and for archived data, and although the write speeds are cool I am not sure its a deal breaker. If I built a new home NAS today I'd probably concentrate the budget on a better CPU, more RAM (for ARC cache) and more disks. However if I had a use case where I frequently accessed the same files and needed to do so in a faster fashion then yes, I'd probably invest in an SSD for caching. I think if you have a spare SSD lying around and you want something fun todo with it, sure chuck it in your ZFS based NAS as a cache mechanism. If you were planning on buying an SSD for caching then I'd really consider your needs and decide if the money can be spent on alternative stuff which would improve your experience with your NAS. I know my NAS would benefit more from an extra stick of RAM and a more powerful CPU, but as a quick evening project with some parts I had hanging around adding some SSD cache was worth a go. More Viewer Interview Questions for Allan News Roundup Setup OpenBSD 6.2 with Full Disk Encryption (https://blog.cagedmonster.net/setup-openbsd-with-full-disk-encryption/) Here is a quick way to setup (in 7 steps) OpenBSD 6.2 with the encryption of the filesystem. First step: Boot and start the installation: (I)nstall: I Keyboard Layout: ENTER (I'm french so in my case I took the FR layout) Leave the installer with: ! Second step: Prepare your disk for encryption. Using a SSD, my disk is named : sd0, the name may vary, for example : wd0. Initiating the disk: Configure your volume: Now we'll use bioctl to encrypt the partition we created, in this case : sd0a (disk sd0 + partition « a »). Enter your passphrase. Third step: Let's resume the OpenBSD's installer. We follow the install procedure Fourth step: Partitioning of the encrypted volume. We select our new volume, in this case: sd1 The whole disk will be used: W(hole) Let's create our partitions: NB: You are more than welcome to create multiple partitions for your system. Fifth step: System installation It's time to choose how we'll install our system (network install by http in my case) Sixth step: Finalize the installation. Last step: Reboot and start your system. Put your passphrase. Welcome to OpenBSD 6.2 with a full encrypted file system. Optional: Disable the swap encryption. The swap is actually part of the encrypted filesystem, we don't need OpenBSD to encrypt it. Sysctl is giving us this possibility.

And this post should also be a reference for other*NIX OSs. The ELF (https://en.wikipedia.org/wiki/Executable_and_Linkable_Format) file is divided into 4 categories: relocatable, executable, shared, and core. Only the executable and shared object files may have dynamic object dependencies, so the ldd only check these 2 kinds of ELF file: (1) Executable. ldd leverages the LD_TRACE_LOADED_OBJECTS environment variable in fact, and the code is as following: if (setenv("LD_TRACE_LOADED_OBJECTS", "true", 1) < 0) err(1, "setenv(LD_TRACE_LOADED_OBJECTS)"); When LDTRACELOADED_OBJECTS is set to 1 or true, running executable file will show shared objects needed instead of running it, so you even not needldd to check executable file. See the following outputs: $ /usr/bin/ldd usage: ldd program ... $ LD_TRACE_LOADED_OBJECTS=1 /usr/bin/ldd Start End Type Open Ref GrpRef Name 00000b6ac6e00000 00000b6ac7003000 exe 1 0 0 /usr/bin/ldd 00000b6dbc96c000 00000b6dbcc38000 rlib 0 1 0 /usr/lib/libc.so.89.3 00000b6d6ad00000 00000b6d6ad00000 rtld 0 1 0 /usr/libexec/ld.so (2) Shared object. The code to print dependencies of shared object is as following: if (ehdr.e_type == ET_DYN && !interp) { if (realpath(name, buf) == NULL) { printf("realpath(%s): %s", name, strerror(errno)); fflush(stdout); _exit(1); } dlhandle = dlopen(buf, RTLD_TRACE); if (dlhandle == NULL) { printf("%sn", dlerror()); fflush(stdout); _exit(1); } _exit(0); } Why the condition of checking a ELF file is shared object or not is like this: if (ehdr.e_type == ET_DYN && !interp) { ...... } That's because the file type of position-independent executable (PIE) is the same as shared object, but normally PIE contains a interpreter program header since it needs dynamic linker to load it while shared object lacks (refer this article). So the above condition will filter PIE file. The dlopen(buf, RTLD_TRACE) is used to print dynamic object information. And the actual code is like this: if (_dl_traceld) { _dl_show_objects(); _dl_unload_shlib(object); _dl_exit(0); } In fact, you can also implement a simple application which outputs dynamic object information for shared object yourself: # include int main(int argc, char **argv) { dlopen(argv[1], RTLD_TRACE); return 0; } Compile and use it to analyze /usr/lib/libssl.so.43.2: $ cc lddshared.c $ ./a.out /usr/lib/libssl.so.43.2 Start End Type Open Ref GrpRef Name 000010e2df1c5000 000010e2df41a000 dlib 1 0 0 /usr/lib/libssl.so.43.2 000010e311e3f000 000010e312209000 rlib 0 1 0 /usr/lib/libcrypto.so.41.1 The same as using ldd directly: $ ldd /usr/lib/libssl.so.43.2 /usr/lib/libssl.so.43.2: Start End Type Open Ref GrpRef Name 00001d9ffef08000 00001d9fff15d000 dlib 1 0 0 /usr/lib/libssl.so.43.2 00001d9ff1431000 00001d9ff17fb000 rlib 0 1 0 /usr/lib/libcrypto.so.41.1 Through the studying of ldd source code, I also get many by-products: such as knowledge of ELF file, linking and loading, etc. So diving into code is a really good method to learn *NIX deeper! Perl5 Slack Syslog BSD daemon (https://clinetworking.wordpress.com/2017/10/13/perl5-slack-syslog-bsd-daemon/) So I have been working on my little Perl daemon for a week now. It is a simple syslog daemon that listens on port 514 for incoming messages. It listens on a port so it can process log messages from my consumer Linux router as well as the messages from my server. Messages that are above alert are sent, as are messages that match the regex of SSH or DHCP (I want to keep track of new connections to my wifi). The rest of the messages are not sent to slack but appended to a log file. This is very handy as I can get access to info like failed ssh logins, disk failures, and new devices connecting to the network all on my Android phone when I am not home. Screenshot (https://clinetworking.files.wordpress.com/2017/10/screenshot_2017-10-13-23-00-26.png) The situation arose today that the internet went down and I thought to myself what would happen to all my important syslog messages when they couldn't be sent? Before the script only ran an eval block on the botsend() function. The error was returned, handled, but nothing was done and the unsent message was discarded. So I added a function that appended unsent messengers to an array that are later sent when the server is not busy sending messages to slack. Slack has a limit of one message per second. The new addition works well and means that if the internet fails my server will store these messages in memory and resend them at a rate of one message per second when the internet connectivity returns. It currently sends the newest ones first but I am not sure if this is a bug or a feature at this point! It currently works with my Linux based WiFi router and my FreeBSD server. It is easy to scale as all you need to do is send messages to syslog to get them sent to slack. You could sent CPU temp, logged in users etc. There is a github page: https://github.com/wilyarti/slackbot Lscpu for OpenBSD/FreeBSD (http://nanxiao.me/en/lscpu-for-openbsdfreebsd/) Github Link (https://github.com/NanXiao/lscpu) There is a neat command, lscpu, which is very handy to display CPU information on GNU/Linux OS: $ lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 32 On-line CPU(s) list: 0-31 Thread(s) per core: 2 Core(s) per socket: 8 Socket(s): 2 But unfortunately, the BSD OSs lack this command, maybe one reason is lscpu relies heavily on /proc file system which BSD don't provide, :-). TakeOpenBSD as an example, if I want to know CPU information, dmesg should be one choice: $ dmesg | grep -i cpu cpu0 at mainbus0: apid 0 (boot processor) cpu0: Intel(R) Core(TM)2 Duo CPU P8700 @ 2.53GHz, 2527.35 MHz cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM, PBE,SSE3,DTES64,MWAIT,DS-CPL,VMX,SMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,SSE4.1,XSAVE,NXE,LONG,LAHF,PERF,SENSOR cpu0: 3MB 64b/line 8-way L2 cache cpu0: apic clock running at 266MHz cpu0: mwait min=64, max=64, C-substates=0.2.2.2.2.1.3, IBE But the output makes me feeling messy, not very clear. As for dmidecode, it used to be another option, but now can't work out-of-box because it will access /dev/mem which for security reason, OpenBSD doesn't allow by default (You can refer this discussion): $ ./dmidecode $ dmidecode 3.1 Scanning /dev/mem for entry point. /dev/mem: Operation not permitted Based on above situation, I want a specified command for showing CPU information for my BSD box. So in the past 2 weeks, I developed a lscpu program for OpenBSD/FreeBSD, or more accurately, OpenBSD/FreeBSD on x86 architecture since I only have some Intel processors at hand. The application getsCPU metrics from 2 sources: (1) sysctl functions. The BSD OSs provide sysctl interface which I can use to get general CPU particulars, such as how many CPUs the system contains, the byte-order of CPU, etc. (2) CPUID instruction. For x86 architecture, CPUID instruction can obtain very detail information of CPU. This coding work is a little tedious and error-prone, not only because I need to reference both Intel and AMD specifications since these 2 vendors have minor distinctions, but also I need to parse the bits of register values. The code is here (https://github.com/NanXiao/lscpu), and if you run OpenBSD/FreeBSD on x86 processors, please try it. It will be better you can give some feedback or report the issues, and I appreciate it very much. In the future if I have other CPUs resource, such as ARM or SPARC64, maybe I will enrich this small program. *** Beastie Bits OpenBSD Porting Workshop - Brian Callahan will be running an OpenBSD porting workshop in NYC for NYC*BUG on December 6, 2017.

The wait is over, 11.0 of FreeBSD has (officially) launched. We'll have coverage of this, plus a couple looks back at UNIX history, and a crowd-favorite guest today. This episode was brought to you by Headlines FreeBSD 11.0-RELEASE Now Available (https://lists.freebsd.org/pipermail/freebsd-announce/2016-October/001760.html) FreeBSD 11.0-RELEASE is now officially out. A last minute reroll to pickup OpenSSL updates and a number of other security fixes meant the release was a little behind schedule, and shipped as 11.0-RELEASE-p1, but the release is better for it Improved support for 802.11n and various wifi drivers Support for the AArch64 (arm64) architecture has been added. Native graphics support has been added to the bhyve(8) hypervisor. A new flag, “onifconsole” has been added to /etc/ttys. This allows the system to provide a login prompt via serial console if the device is an active kernel console, otherwise it is equivalent to off. The xz(1) utility has been updated to support multi-threaded compression. A number of kernel panics related to VNET have been fixed The IMAGACT_BINMISC kernel configuration option has been enabled by default, which enables application execution through emulators, such as QEMU via binmiscctl(8). The GENERIC kernel configuration has been updated to include the IPSEC option by default. The kern.osrelease and kern.osreldate are now configurable jail(8) parameters A new sysctl(8), kern.racct.enable, has been added, which when set to a non-zero value allows using rctl(8) with the GENERIC kernel. A new kernel configuration option, RACCT_DISABLED has also been added. The minimum (arcmin) and maximum (arcmax) values for the ZFS adaptive replacement cache can be modified at runtime. Changes to watch out for: OpenSSH DSA key generation has been disabled by default. It is important to update OpenSSH keys prior to upgrading. Additionally, Protocol 1 support has been removed. By default, the ifconfig(8) utility will set the default regulatory domain to FCC on wireless interfaces. As a result, newly created wireless interfaces with default settings will have less chance to violate country-specific regulations. An issue was discovered with Amazon® EC2™ images which would cause the virtual machine to hang during boot when upgrading from previous FreeBSD versions. New EC2™ installations are not affected, but existing installations running earlier releases are advised to wait until the issue is resolved in an Errata Notice before upgrading. An Errata Notice to address this is planned following the release. *** process listing consistency (http://www.tedunangst.com/flak/post/process-listing-consistency) Ted Unangst asks: how consistent is the output of ps(1)? If processes are starting and exiting constantly, and you run ps(1), is the output guaranteed to reflect that exact moment in time, or might it include some processes that have gone away before ps(1) exited, and include some processes that did not exist when ps(1) was started? Ted provides a little example chicken/egg program to try to create such an inconsistency, so you can test out your OS On OpenBSD ps(1) was switched away from the reading kernel memory directly, and instead uses the KERNPROCALL sysctl Thus sysctl can iterate over the entire process list, copying out information to ps(1), without blocking. If we prevent processes from forking or exiting during this time, we get a consistent snapshot. The snapshot may be stale, but it will never show us a viewpoint that never happened. So, OpenBSD will always be consistent, or will it? Is there a way to trick ps on OpenBSD? Not everything is consistent. There's a separate sysctl, KERNPROCARGV, that reads the command line arguments for a process, but it only works on one process at a time. Processes can modify their own argv at any time. A second test program changes the process title of both the chicken and the egg, and if you run ps(1), you can get back a result that never actually happened. The argv of the first program is read by ps(1), and in the meantime, it changes to a different value. The second program also changes its value, so now when ps(1) reads it, it sees the new value, not the original value from when ps(1) was started. So the output is not that consistent, but is it worth the effort to try to make it so? DragonFlyBSD - if_iwm - Add basic powermanagement support via ifconfig wlan0 powersave (http://lists.dragonflybsd.org/pipermail/commits/2016-October/624673.html) WiFi can often be one of the biggest drains on your laptop battery, so anything we can do to improve the situation should be embraced. Imre Vadász over at the DragonFly project has done that, porting over a new set of power management support from Linux to the if_iwm driver. if_iwm - Add basic powermanagement support via ifconfig wlan0 powersave. The DEVICEPOWERFLAGSCAMMSK flag was removed in the upstream iwlwifi in Linux commit ceef91c89480dd18bb3ac51e91280a233d0ca41f. Add scpsdisabled flag to struct iwmsoftc, which corresponds to mvm->psdisabled in struct iwl_mvm in Linux iwlwifi. Adds a hw.iwm.powerscheme tunable which corresponds to the powerscheme module parameter in Linux iwlwifi. Set this to 1 for completely disabling power management, 2 (default) for balanced powermanagement, and 3 for lowerpower mode (which does dtim period skipping). Imports the constants.h file from iwlwifi as ifiwmconstants.h. This doesn't allow changing the powermanagement setting while connected, also one can only choose between enabled and disabled powersaving with ifconfig (so switching between balanced and low-power mode requires rebooting to change the tunable). After any changes to powermanagement (i.e. "ifconfig wlan0 powersave" to enable powermanagement, or "ifconfig wlan0 -powersave" for disabling powermanagement), one has to disconnect and reconnect to the accespoint for the change to take effect.“ Good stuff! These positive changes need to happen more often and sooner, so we can all eek out every drop of power from our respective laptops. *** Helping out an Internet Friend…Dual boot OpenBSD (https://functionallyparanoid.com/2016/10/03/helping-out-an-internet-friend/) Dual-booting OpenBSD and Linux, via UEFI. A year ago we wouldn't be discussing this, but today we have an article where somebody has done exactly that. This Journey was undertaken by Brian Everly (Indiana Bug), partly due to a friend who wanted to dual-boot his laptop which already has an existing UEFI install on it. As a proof of concept, he began by replicating the setup in VMware with UEFI He started by throwing Ubuntu into the VM, with some special attention paid to partitioning to ensure enough room left-over for OpenBSD later. I created a 64MB EFI partition at the front of the disk. Next, I created a 20GB primary partition at the beginning of the space, mounted as the root (/) filesystem. I then added a 4096MB swap partition for Ubuntu. Finally, I used the rest of the free space to create a Reserved BIOS Boot Area FAT32 partition that was not associated with a mount point – this is where I will be installing OpenBSD. With that done, he wrapped up the Ubuntu installation and then turned over to to the OpenBSD side. Some manual partitioning was required to install to the “Reserved FAT32” partition. I mashed through the defaults in the OpenBSD installer until I got to the disk partitioning. Since I told VMWare to make my hard drive an IDE one, I knew I was playing around with wd0 and not sd0 (my USB key). I dumped into fdisk by selecting to (E)dit the partition scheme and saw my setup from Linux. First was the EFI partition (I am guessing I'll have to copy my bootx64.efi file to that at some point), second was the Linux etx4 partition, third was my Linux swap partition and fourth was a weird looking one that is the “Reserved BIOS Boot” partition. That's the one I'll fiddle with. Issuing the command “edit 3” allowed me to fiddle with that partition #3 (remember, we start counting at zero). I set it's type to “A6” (OpenBSD) and then took the defaults with the exception of naming it “OpenBSD”. A quick “write” followed by a “quit” allowed me to update my new partition and get back to the installer. Once the installation was wrapped up (OpenBSD helpfully already created the /boot/EFI partition with the correct EFI loader installed) he was able to reboot and select between the two systems at the UEFI bios screen. For kicks, he lastly went into Ubuntu and grabbed refind. Installing refind provided a fancy graphical selector between the two systems without too much trouble. Next step will be to replicate this process on his friend's laptop. Wishing you luck with that journey! Interview - Bryan Cantrill - email@email (mailto:email@email) / @twitter (https://twitter.com/user) CTO of Joyent *** News Roundup After 22 Years, 386BSD Gets An Update (https://bsd.slashdot.org/story/16/10/09/0230203/after-22-years-386bsd-gets-an-update) Slashdot brings us an interesting mention this week, specifically that after 22 years, we now have an update to 386BSD. 386BSD was last released back in 1994 with a series of articles in Dr. Dobb's Journal -- but then developers for this BSD-based operating system started migrating to both FreeBSD and NetBSD. An anonymous Slashdot reader writes: The last known public release was version 0.1. Until Wednesday, when Lynne Jolitz, one of the co-authors of 386BSD, released the source code to version 1.0 as well as 2.0 on Github. 386BSD takes us back to the days when you could count every file in your Unix distribution and more importantly, read and understand all of your OS source code. 386BSD is also the missing link between BSD and Linux. One can find fragments of Linus Torvalds's math emulation code in the source code of 386BSD. To quote Linus: "If 386BSD had been available when I started on Linux, Linux would probably never had happened.” Though it was designed for Intel 80386 microprocessors, there's already instructions for launching it on the hosted hardware virtualization service Qemu. There you have it! Go grab the new hotness that is 386BSD and run it in 2016! Or perhaps you want FreeBSD 11, but to each their own. *** Progress of the OpenBSD Limited Edition Signed CD set (http://undeadly.org/cgi?action=article&sid=20160929230557&mode=expanded) An update from a story last week!

(With proceeds to support for Foundation) As of today, here's where we stand: CD set #1 (Sep 29th + 5 days) sold for $4200 (http://www.ebay.com/itm/-/331985953783) CD set #2 (Oct 4th + 3 days) sold for $3000 (http://www.ebay.com/itm/-/331990536246) CD set #3 (Oct 8th + 3 days) sold for $817 (http://www.ebay.com/itm/-/331994217419) CD set #4 (Oct 11th + 3 days) is currently up for bidding (http://www.ebay.com/itm/-/331997031152) There you have it! The 4th set is almost wrapped up bidding, and the 5th and last set is not far behind. Be sure to grab your piece of BSD history before its gone! PROTOTYPE FreeBSD Jail/ZFS based implementation of the Application Container Specification (https://github.com/3ofcoins/jetpack) “Jetpack is an experimental and incomplete implementation of the App Container Specification for FreeBSD. It uses jails as isolation mechanism, and ZFS for layered storage.” “This document uses some language used in Rocket, the reference implementation of the App Container Specification. While the documentation will be expanded in the future, currently you need to be familiar at least with Rocket's README to understand everything.” + A standard with multiple implementations, that allow substitution of components, such as FreeBSD Jails instead of docker/lxc etc, and ZFS instead of overlayfs etc, is very exciting Microsoft's Forgotten Unix-based Operating System (https://fossbytes.com/xenix-history-microsoft-unix-operating-system/) Do you remember the good old days. You know, when Microsoft was the driving force behind UNIX? Wait, what did you say you may be thinking? It's true, and lets sit back and let FossBytes tell us a tale of what once was reality. The story begins sometime in the late 70's: Turning back the pages to the late 1970's, Microsoft entered into an agreement with AT&T Corporation to license Unix from AT&T. While the company didn't sell the OS to public, it licensed it to other OEM vendors like Intel, SCO, and Tandy. As Microsoft had to face legal trouble due to “Unix” name, the company renamed it and came up with its own Unix distribution. So, AT&T licensed Unix to Redmond that was passed on to other OEMs as Xenix. It's interesting to recall a time when Microsoft enabled people to run Unix — an operating system originally designed for large and multiuser systems — on a microcomputer. Even though it came first, Unix was probably more powerful than MS-DOS. So whatever happened to this microsoft-flavored UNIX you may ask? Sadly it was ditched for DOS due to $REASONS: In early 1980's, IBM was looking for an OS to power its PC. As IBM didn't want to maintain any ties with the recently split AT&T, Xenix was automatically rejected. To fulfill, the tech giant's demand, Microsoft bought 86-DOS from Seattle Computer Products and managed to convince IBM to use it in their systems. Slowly, Microsoft started losing interest in Xenix and traded the full rights of Xenix with SCO, a Xenix partner company. The company filed bankruptcy in 2007 before taking the Xenix legacy to the 21st century in the form of Open Server, previously known as SCO Unix and SCO Open Desktop. An interesting chapter in UNIX history to be sure, and funny enough may come full-circle someday with Microsoft beginning to show interest in UNIX and BSD once again. *** Beastie Bits Ohio LinuxFest 2016 wrap-up (http://blather.michaelwlucas.com/archives/2791) Learn X in Y minutes Where X=zfs (https://learnxinyminutes.com/docs/zfs/) Add touchscreen support for the official 7" RPi touch display (https://svnweb.freebsd.org/base?view=revision&revision=306430) 64-bit U-Boot on Raspberry Pi 3 (https://kernelnomicon.org/?p=682) SNIA SDC 2016 Recap: Michael Dexter (https://www.ixsystems.com/blog/snia-sdc-2016-recap-michael-dexter/) OpenZFS: Stronger than ever (https://www.ixsystems.com/blog/openzfs-devsummit-2016/) Accurate, Traceable, and Verifiable Time Synchronization for World Financial Markets (http://nvlpubs.nist.gov/nistpubs/jres/121/jres.121.023.pdf) ON HOLY WARS AND A PLEA FOR PEACE (https://www.ietf.org/rfc/ien/ien137.txt) Feedback/Questions Morgan - Zero-Filling an VM (http://pastebin.com/CYcqmW7P) Charlie - ZFS Bit-Rot (http://pastebin.com/12mNW57h) Matias - TrueOS / Launchd (http://pastebin.com/NfYWt2cu) Dale - DO Feedback (http://pastebin.com/UvKh2WcF) James - DO / FreeBSD Locks?

BCoin is a bitcoin client which implements BIP-37. It can track transactions, public keys, and public key hashes (bitcoin addresses) without saving the entire blockchain to disk. This means you can have a wallet with a synchronized balance and send and receive payments without keeping track of a 20GB database. BCoin is implemented in pure javascript, and is browserify-able (this means compiling a binding to an ECDSA library is not even required for node.js). For us, the fact that peer to peer communication is not encrypted on the Bitcoin network seems like more of an oversight to me than anything else. They now have begun integrating the Lightning Network. It's called "blight". Purse.io takes over this episode as both Christopher Jeffrey (JJ) who is the CTO & Engineer at Purse and podcast regular Steven McKie join us in the studio. We continue to give you that mid-week goodness.

It's our 50th episode, and we're going to show you how to protect your internet traffic with a BSD-based VPN. We'll also be talking to Robert Watson, of the FreeBSD core team, about security research, exploit mitigation and a whole lot more. The latest news and answers to all of your emails, on BSD Now - the place to B.. SD. This episode was brought to you by Headlines MeetBSD 2014 is approaching (http://www.ixsystems.com/whats-new/ixsystems-to-host-meetbsd-california-2014-at-western-digital-in-san-jose/) The MeetBSD conference is coming up, and will be held on November 1st and 2nd in San Jose, California MeetBSD has an "unconference" format, which means there will be both planned talks and community events All the extra details will be on their site (https://www.meetbsd.com/) soon It also has hotels and various other bits of useful information - hopefully with more info on the talks to come Of course, EuroBSDCon is coming up before then *** First experiences with OpenBSD (https://www.azabani.com/2014/08/09/first-experiences-with-openbsd.html) A new blog post that leads off with "tired of the sluggishness of Windows on my laptop and interested in experimenting with a Unix-like that I haven't tried before" The author read the famous "BSD for Linux users (http://www.over-yonder.net/~fullermd/rants/bsd4linux/01)" series (that most of us have surely seen) and decided to give BSD a try He details his different OS and distro history, concluding with how he "eventually became annoyed at the poor quality of Linux userland software" From there, it talks about how he used the OpenBSD USB image and got a fully-working system He especially liked the simplicity of OpenBSD's "hostname.if" system for network configuration Finally, he gets Xorg working and imports all his usual configuration files - seems to be a happy new user! *** NetBSD rump kernels on bare metal (and Kansai OSC report) (https://blog.netbsd.org/tnf/entry/an_internet_ready_os_from) When you're developing a new OS or a very specialized custom solution, working drivers become one of the hardest things to get right However, NetBSD's rump kernels - a very unique concept - make this process a lot easier This blog post talks about the process of starting with just a rump kernel and expanding into an internet-ready system in just a week Also have a look back at episode 8 (http://www.bsdnow.tv/episodes/2013_10_23-a_brief_intorduction) for our interview about rump kernels and what exactly they do While on the topic of NetBSD, there were also a couple of very detailed reports (http://mail-index.netbsd.org/netbsd-advocacy/2014/08/09/msg000658.html) (with lots of pictures!) of the various NetBSD-themed booths at the 2014 Kansai Open Source Conference (http://d.hatena.ne.jp/mizuno-as/20140806/1407307913) that we wanted to highlight *** OpenSSL and LibreSSL updates (https://www.openssl.org/news/secadv_20140806.txt) OpenSSL pushed out a few new versions, fixing multiple vulnerabilities (nine to be precise!) Security concerns include leaking memory, possible denial of service, crashing clients, memory exhaustion, TLS downgrades and more LibreSSL released a new version (http://marc.info/?l=openbsd-tech&m=140752295222929&w=2) to address most of the vulnerabilities, but wasn't affected by some of them Whichever version of whatever SSL you use, make sure it's patched for these issues DragonFly and OpenBSD are patched as of the time of this recording but, even after a week, NetBSD and FreeBSD are not (outside of -CURRENT) *** Interview - Robert Watson - rwatson@freebsd.org (mailto:rwatson@freebsd.org) FreeBSD architecture, security research techniques, exploit mitigation Tutorial Protecting traffic with a BSD-based VPN (http://www.bsdnow.tv/tutorials/openvpn) News Roundup A FreeBSD-based CGit server (https://lechindianer.de/blog/2014/08/06/freebsd-cgit/) If you use git (like a certain host of this show) then you've probably considered setting up your own server This article takes you through the process of setting up a jailed git server, complete with a fancy web frontend It even shows you how to set up multiple repos with key-based user separation and other cool things The author of the post is also a listener of the show, thanks for sending it in! *** Backup devices for small businesses (http://www.smallbusinesscomputing.com/biztools/6-data-backup-devices-for-small-businesses.html) In this article, different methods of data storage and backup are compared After weighing the various options, the author comes to an obvious conclusion: FreeNAS is the answer He praises FreeNAS and the FreeNAS Mini for their tight integration, rock solid FreeBSD base and the great ZFS featureset that it offers It also goes over some of the hardware specifics in the FreeNAS Mini *** A new Xenocara interview (http://blog.bronevichok.ru/2014/08/06/testing-of-xorg.html) As a follow up to last week's OpenSMTPD interview, this Russian blog interviews Matthieu Herrb about Xenocara If you're not familiar with Xenocara, it's OpenBSD's version of Xorg with some custom patches In this interview, he discusses how large and complex the upstream X11 development is, how different components are worked on by different people, how they test code (including a new framework) and security auditing Matthieu is both a developer of upstream Xorg and an OpenBSD developer, so it's natural for him to do a lot of the maintainership work there *** Building a high performance FreeBSD samba server (https://not.burntout.org/blog/high_performance_samba_server_on_freebsd/) If you've got to PXE boot several hundred Windows boxes to upgrade from XP to 7, what's the best solution? FreeBSD, ZFS and Samba obviously! The master image and related files clock in at over 20GB, and will be accessed at the same time by all of those clients This article documents that process, highlighting some specific configuration tweaks to maximize performance (including NIC bonding) It doesn't even require the newest or best hardware with the right changes, pretty cool *** Feedback/Questions An interesting Reddit thread (http://www.reddit.com/r/BSD/comments/2ctlt4/switched_from_arch_linux_to_openbsd_reference/) (or two (http://www.reddit.com/r/BSD/comments/2dcig9/thinking_about_coming_to_bsd_from_arch)) PB writes in (http://slexy.org/view/s21t7L5bqO) Sean writes in (http://slexy.org/view/s20MFywDqZ) Steve writes in (http://slexy.org/view/s2Td6nq11J) Lachlan writes in (http://slexy.org/view/s215MlpJYV) Justin writes in (http://slexy.org/view/s2N4JKkoKt) ***
