(Colin about episode 65)
Hello Everyone,

Really appreciate the podcast, thanks a lot to all of you.
Just to let you know I downloaded episode 65 Oct 22nd and through tablet speakers or wired earphones or a new Bluetooth speaker the volume is so low you cannot realistically listen I’m afraid. I immediately switched to another podcast at the same volume and it boomed through.
Hopefully this is useful feedback.
Thanks again for the regular podcasts I am really enjoying the show.
Colin,

Hi,

I might be able to help with your networking issues.  I use Arch on Pi2 and my laptop.

You can either use wifi-menu to generate a network profile, or copy from /etc/netctl/examples to /etc/netctl/
To enable to profile, use <systemctl enable netctl@wlan_network_profile.service> and <systemctl start netctl@wlan_network_profile.service>
Be mindful of the not using a profile name with a dash in the name, but an underscore instead.  The profile fails to start with a dash.

Here is an example profile.

Interface=wlan0
Connection=wireless
Security=wpa
ESSID=ATTxxxx
IP=dhcp
WPAConfigFile=’/etc/wpa_supplicant/wpa_supplicant.conf’
Key=\”key_generated_by_wpa_passphrase
### \” before the key does matter, it won’t work otherwise
TimeoutDHCP=30

usage: wpa_passphrase <ssid> [passphrase]

And last, at the end of wpa_supplicant.conf

network={
ssid=”ATT159″
#psk=”3678167014″
psk=”03cbedf25145ce6c304b41946a47c854dd27b34058a141a7ec89cc270b13c9cb”
}

Netminer
I have found a nice low power Pfsense Box.   It has 4 Intel NICs, either a J1900 Quad core or
3215U dual core Intel processor and up to 8Gigs of Ram.  It is the QOTOM Q190G4.   The -S1 version supports an MSATA SSD, while the -S2 version can have 2.5 inch hard drive.
The units are very low power fanless industrial computers.  They are cool thru a finned metal
Top.  They are available from Amazon and Aliexpress

Temporary fix to give my server Internet access.  “sudo route add default gw RouterIP eth0
Thanks to Joshua Mason on G+ who suggested a gateway problem, which I confirmed with “sudo route -n”  that confirmed my gateway was set to “0.0.0.0”.  The gateway is still set as my router’s IP in /etc/systemd/network/eth0.network as documented in ep 59.

I finally successfully casted video to my Chrome Cast from my Linux desktop using the
prebuilt Virtual Box .VDI image of RemixOS (http://www.osboxes.org/remix-os/)  Kwisher recomended two episodes back.

Having a weird problem with my Arch install on my RPi v1 B+.  I can connect to hosts on the local network, but not on the Internet.  This happens even when I resolve the URL to an IP, so it’s not DNS.  I changed my router so it’s no longer using Pi-Hole,and I’ve made no other changes recently.

Running Android apps on Linux part 2:  Running Remix OS for x86 in a VM – FAIL  http://www.osboxes.org/remix-os/
Network Monitor project progress: Diet Pi on RPi2, Pi-Hole works, TOR AP – can see SSID but not connect, OwnClound not found (probably because of Pi-Hole), Nagios (installed from Debian repo) not found.
Finally put a system on my Pine 64.  Tried several from the Wiki page before one worked.
{ http://wiki.pine64.org/index.php/Pine_A64_Software_Release }
Ubuntu/Mate for Pine 64 did not boot, Debian/Mate by lenny.raposo booted but never made it to login, Ubuntu by Michael Larson got to desktop, but popped up a dialog stating “Ubuntu  16.04 has experienced an internal error” details (usr/bin/xfce-panel) that persisted after upgrade.  Arch/xfce works.

Follow-up on my adventures with Hugo (static website generator written in Go)
Set up of a simple single-page site is surprisingly easy if you use one of the many themes that are available. In my case, I used a theme called Highlights.

For multi-page, blog-style sites, the documentation (http://gohugo.io/overview/quickstart/) is really quite helpful. Not much need to search outside of that.

I managed to migrate another site from Ghost to Hugo in just over an hour. A big help for that was a Python script called ‘ghost2hugo’ by Matthew Bentley (https://github.com/matthewbentley/ghost2hugo/). The script pulls the Markdown content from Ghost’s sqlite database and saves those posts as text files. Then there’s just a little bit of modification necessary to get things up and running (partially depending on how many posts you have and the number of customizations you’ve done to the theme).

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.
