    Slackware-14.1-Pdnsd 1.2.9a

    Very cool! :-) Thanks for the pointer. I've been wanting something like this for some years, but BIND running as a local caching nameserver and near-network forwarders has been "good enough", so I didn't look too hard. Will give pdnsd a spin :-)

    home network topology

    If you're looking for something to jfw immediately, and don't mind spending the money, then the off-the-shelf wifi extender seems like the obvious way to go.

    You say it's not exactly a burningly urgent need, though, so if you want to save some money and perhaps learn some familiarity with the technology, getting ddrt working on a second-hand WAP has a lot of appeal.

    I'd go with ddrt-on-cheap-WAP if I had the time and energy for the project. It's knowledge which will only grow more valuable in the years to come.

    OpenBSD /etc/ipsec.conf for AWS VPC VPN

    I forgot to mention, for failover purposes, you should put the following in /etc/ipsec.conf:

    include "/etc/ipsec/aws-$TUNNEL1-IP.conf"
    include "/etc/ipsec/aws-$TUNNEL2-IP.conf"

    Then put each tunnel in its own "/etc/ipsec/aws-$TUNNEL#-IP.conf" file. To failover from tunnel 1 to tunnel 2, then, you can:

    ipsecctl -df /etc/ipsec/aws-$TUNNEL1-IP.conf && ipsecctl -f /etc/ipsec/aws-$TUNNEL2-IP.conf

    Testing on my side shows the failover occurs in ~4-6 seconds.

    Four days. I've done this a few times now over the years: dual-booted with Debian, and got fed-up with it after a short time. Why? No idea.

    I now have four working home systems, two desktops and two laptops

    My current environment continues to include two of the previously mentioned laptops, Gateway 17" PA6A laptop and the Lenovo 3000 Y410. I got rid of the desktop systems. I do have a prototype Chromebook CR-48 but I have not recently used it. What's been added are phones and tablets. I currently own a MOTO X phone and a Nexus 7 tablet and I have access to a few other types used by family members too.

    Itching to write a new GPC article

    That is really different. Thanks for explaining your interest.

    Increased the RAM in the X200 to its "official" maximum: 4 GB.
    There are "unofficial" maximums, but I reckon 4 is plenty for me.

    Itching to write a new GPC article

    Somewhat indirectly.

    About fifteen years ago, I became interested in the material science of composite armor. One of my mentors in the subject, Paul Lakowski, invited me to the Tank-Net military forums, where I became acquainted with Anthony Williams, who is championing the GPC concept to the UK Defense Ministry and is a Tank-Net regular.

    In order to understand armor, and to design armor to defeat a threat, it is necessary to become familiar with the threat it needs to defeat, which meant that my interest necessarily spilled over into the study of things which seek to penetrate armor -- long-rod penetrators, shaped charges, shell case fragments, and bullets.

    To this end, I had already built out a few formulae for predicting the ballistic behavior of small-arms projectiles. Tank-Net is a gift culture, where everyone helps everyone else with their interests, and gets helped in turn with their own -- kind of like LQ, but with militaria rather than Linux. In this spirit, I tried to apply my formulae to the GPC discussions, to foment better understanding.

    I quickly discovered that my formulae (which mostly dealt with penetration) were woefully insufficient to the subject. The GPC issue touches on matters of internal and external ballistics, and on more terminal ballistics than just penetration. Just as important are munition total weight, barrier defeat, and wounding, which I'd never considered before.

    An engineer's got to engineer, and I've been digging in and figuring things out, collecting other people's formulae and a few of my own into Ballistics Perl modules which I can use in my perl calculator. These are still very much under development, and likely will be for some time.

    The formula for estimating the weight of empty brass cartridges is somewhat wrong, for instance. It is fairly accurate when a cartridge was designed for a given volume and peak pressure, but many cartridges are actually derived from larger/heavier cartridges (the 6mm PPC from the .220 Russian, for instance, and the .243 WSSM from the .300 WSM), which makes them heavier than they "need" to be, and heavier than Physics::Ballistics::Internal::empty_brass() predicts. Thus some of the weights in my second GPC article are wrong, which is something the third GPC article will address.

    I've started writing that article, but it's slow going. I want to touch on a wider variety of topics in it than I did in the first two articles, and it's in competition with other personal projects for my time and attention.

    Slackware-14.1-DnsCrypt Proxy 1.4.3

    Cool setup. I have a similar deal with unbound caching via dnscrypt to a dnscrypt server I operate and via tor for all onion addresses. Nice to see other LQers looking into dnscrypt =)

    mpd/mpc is always a headache

    I'll check it out, thanks.

    I've also considered sort of making my own "daemon" with some single command line player, but usually it happened just before figuring out some way of making MPD/MPC work.

    And speaking of audio-related things to check out, I think I've just found recently a console UI for youtube, but I haven't checked yet: "mpsyt (1) - Terminal based YouTube jukebox with playlist management". It seems really great if you're just interested in the audio, even though perhaps it will open a window or play the video in the framebuffer, I don't know, but I'm hoping there's a audio-only option.

    Mostly a note to myself now, just because I'm too lazy to edit the OP: By the way, perhaps currently it's working in one install and not in other because the working version is a pinned previous version, which I didn't remember. May or may not have something to do with the troublesome version being compiled with "libwrap" or something, according to Arch linux forums. So in the future, if I'm still using Debian, and see myself needing to update it, maybe I should compile an update version without this option-thing, if it still doesn't work.

    Many slackers like MOC (Music On Console), you might want to give that a look. I used to use mpd/mpc and was really happy with it, never had any issues running it at all, but it was overkill for what I needed.

    These days, I've gone completely minimal/retro and just use 'play' from the 'sox' suite of sound utils.

    Its you know where your packets are?

    Oh, I have an SLA on my home network, trust me...and I don't mean "Comcast's side", I mean "that stack of 8 machines running on, under, and around your desk that overheats the office and sounds like a boeing 747" SLA.

    My wife doesn't claim *any* ownership of that stack of machines haha.

    It's always "your firewall." Don't you use the internet too? It's "our firewall" just like it's "our bank account". It's bad enough when it's the kid, but when the spouse throws that out too......
