1)Manually configuring a static IP in Arch with systemd:  systemd no longer defaults to /etc/system/interfaces to determine your network settings.  The Arch wiki instead directs you to pick the most appropriate network profile from /etc/netctl/examples, copy/rename it into /etc/netctl, edit it to fit your situation, and change your config via “sudo netctl start profile” and make it permanent via “sudo netctl enable profile”.  
[ https://wiki.archlinux.org/index.php/Network_configuration#Static_IP_address ]Unfortunately, the start command gave me errors, the enable command did not, but after a reboot, my server IP was still determined by DHCP.

Since netctrl was obviously supposed to just copy parameters into a config file, I looked into just editing that file directly.   My answer came from Linode
( https://www.linode.com/docs/networking/linux-static-ip-configuration ).  Edit /etc/systemd/network/interface.network directly.  My RPI server’s file looks like:

[Match]
Name=eth0
Host=barsoom

[Network]
#DHCP=both
Gateway=192.168.2.1
Address=192.168.2.50/24
DNS=192.168.2.1


2)Forcibly resetting root password:  There is no security but physical security.  Editing the /etc/shadow file.  Recently, I set up DietPi to try to get Pi-hole and Nagios on the same machine.  Somehow, the final step in DietPi config fouled up resetting the password w/o reinstalling.

1. Mount the SD card in another machine

2. Locate file /etc/shadow

1. In the first line, delete everything between “root:” and the next colon, i.e, line will now be root::random_string

2. Unmount SD

3. Boot as root on Pi

1. Create new password

As cheap as Pi’s are, I don’t feel I should have to buy one for each task (i.e., I’d like to put Pi-Hole and Nagios on the same box). I’m hoping the community can come together to give me a solution.

We all discuss what Linux systems we are running and why

Browsers seg fault, except Midori.  You have to let Midori install gstreamer before you can see YouTube videos (after reboot).  This also allows you to see video in VLC, but performance is unusable.  Default mixed was unable to connect to HDMI audio in my monitor, but Pulse Audio Volume Control made it work.  Kodi’s interface was too sluggish to be usable as well.  Not many distros have binary images yet.  Default is Ubuntu Mate.  I also found ODRObeian vanilla, but it has no GUI http://oph.mdrjr.net/odrobian/images/s905/ OpenElec and LibreElec are still being worked on, I understand some people are running Arch, but I couldn’t find a link.  Lakka is working on a 64 bit port.

OpenToonz (hand-drawn animation software) was released. No Linux version just yet, but it’s Qt5 and it’s been released under a modified BSD license, so it’s only a matter of time (https://opentoonz.github.io/e/index.html)

Mailing List:  Kevin Wisher explains that with the paid version of Crashplan, the company provides cloud storage and with the free version you only get two nodes.

Google+  Joshua Mason started a discussion about segmenting networks via MAC address rather than IP.   Father Finch explained while networks could be segmented via “vlan tags”, this would require every host on the network to recognize vlan tags, which wouldn’t be practical with IOT devices.

Little personal announcement. I was invited to give one of the Lightning Talks at the Great Wide Open conference in Atlanta on March 17th (http://greatwideopen.org/talks/lightning-talks-hosted-by-opensource-com/). If you’re going to be there, perhaps you can drop by and watch me flail about for 5 minutes.

If there’s time (probably not ;), I’d like to talk about doing secure offsite back-ups. Right now, the solution with the greatest appeal looks to be Duplicity or Duply pushing to Amazon S3 (reference tutorial: http://old.blog.phusion.nl/2013/11/11/duplicity-s3-easy-cheap-encrypted-automated-full-disk-backups-for-your-servers/). I’d love to hear other solutions that anyone has used or is using. Let’s discuss it more on the mailing list.

SaveWiFi.org revisited.  Chris Waid responded to an e-mail I wrote back in November where I linked an article.  The article said the EFF no longer feared the FFC would force manufacturers of routers to lock out third party firmware.  Chris’ response was that he is still unimpressed with the response from the FCC and sent me this link http://wwahammy.com/seriously-the-fcc-might-still-ban-your-operating-system/    Also, Claudio Miranda posted this link to Facebook yesterday: http://ml.ninux.org/pipermail/battlemesh/2016-February/004379.html

Command Line Tip:  This last week, I installed Samba on my server so my shared storage could be accessed by a customer’s Windows machine.  I got the error:
:: File /var/cache/pacman/pkg/smbclient-4.3.4-1-armv6h.pkg.tar.xz is corrupted (invalid or corrupted package (checksum)).
Do you want to delete it? [Y/n]   I tried again and got the same error, so I searched the web for the filenameand found it on http://us.mirror.archlinuxarm.org/armv6h/extra/  I manually downloaded the file and copied it into /var/cache/pacman/pkg/, re-ran “sudo pacman -S samba” andthis timeI was successful.
