Installing NextCloud on my alumni server (Nano Pi Neo running Armbian Ubuntu)  https://www.linux.com/learn/how-install-nextcloud-server-ubuntu%20%20
When following this tutorial, I had best results when replacing “localhost” with 127.0.0.1

RetrOSMC – https://github.com/mcobit/retrosmc

Only hiccup was a requirement for libudev0. Needed to pull a custom build from here: http://ftp.nl.debian.org/debian/pool/main/u/udev/libudev0_175-7.2_armhf.deb (reference post on a moonlight-embedded issue on Github: https://github.com/irtimmer/moonlight-embedded/issues/206#issuecomment-136179497).

1. Use the following commands to install:

$ wget http://ftp.nl.debian.org/debian/pool/main/u/udev/libudev0_175-7.2_armhf.deb

$ dpkg -i libudev0_175-7.2_armhf.deb

Then re-run the RetroPie-Setup.sh script.

After that you should be good to go

We also discuss Linux security

1. rfkill – Diagnose why your laptop’s WiFi may be turned off.  http://askubuntu.com/questions/62166/siocsifflags-operation-not-possible-due-to-rf-kill

2. RPi image to quickly get Nagios Server up and running http://www.baldnerd.com/nems/ Finally, one that works.

3. Added a USB Ethernet NIC to my pfSense box to segregate IoT devices from my regular network.  “OPT1” seems to be configured identically to “LAN” (except for address range), but it can’t “see” the Internet but I can ping from one LAN to the other (just the opposite of what I wanted).

4. Since the pfSense box has no WiFi (well it does, but pfSense doesn’t recognize it),  I’ve been using the cheaper of my factory routers as a WAP (the other is in reserve, configured in case I break pfSense).  The AP keeps dropping my ChromeCasts, so I was looking into turning one of my Orange Pi Zeros into a simple AP.  Installed Armbian (can’t say enough good things).  Linux has a “bridge” command that creates a virtual interface between network interfaces, but it is meant as a bridge between networks, not an AP.  The MAC address of every device connecting to the WiFi must be enumerated.  After Googling for an easy way to accomplish my goal, at length I found a PPA  here:  http://www.webupd8.org/2013/06/how-to-set-up-wireless-hotspot-access.html  Unfortunately, I’d installed Armbian Debian, went back and downloaded Armbian Ubuntu.  Then, the script the article talks about must be deprecated in the current PPA.  Went through the manual setup, but neither the OPi’s onboard WAN or a USB adapter I bought for my hotel router project seem supported.  This shouldn’t be this difficult, I hope a listener can point me in the right direction.

1. I did some hasty editing Thursday night.  I saw a discounted TP-Link switch on NewEgg (which I plan to use for the IoT guest network)., but when I went to order it, I saw it was available in a combo with a Sonic Wall AP, which I confused with a Ubiquiti AP’s.  The difference is that Sonic Walls require a dedicated hardware controller (from Dell) and the Ubiquiti is managed in cross platform software.  Since I probably will have to send the whole thing back, I am officially an idiot (which will come as no surprise to regular listeners).  I’ve had good success setting up Ubiquitis for customers, and Tom Lawrence has talked about them several times on his YouTube channel.

2. RoxTerm, multi tab terminal emulator for SolusOS, Sunflower, multi tab file manager.
