Temporary fix for updating external HPFS/NTFS/exFAT hard drive’s permissions so Plex can access

When I plugged in my external hard drive that was on Windows to a Linux machine (Raspberry Pi 3), it was automatically mounted at /media/brian/Brian-HD, but the permissions were drw- --- --- 1 brian brian. I needed Plex to be able to see and use the hard drive, but no matter how much I tried to open up permissions, the ls -l command never changed.

Failed attempts to update permissions

sudo -R chmod 660 /media/brian/
sudo addgroup brian plex
sudo addgroup plex brian

Finding out that the drive is an exFAT.

sudo fdisk -l 
Device Boot Start End Sectors Size Id Type 
/dev/sda1 256 488378111 488377856 1.8T 7 HPFS/NTFS/exFAT

What worked for me

PLEX support forums has an article specifically on how to mount NTFS hard drives (but exFAT works too) so you can get permissions for PLEX to see the files. But their article is old and has broken links, so I will restate it with updated links:

# Run and get the UUID of your device
blkid

# Edit /etc/fstab
sudo nano /etc/fstab

# Add this line to the bottom 
UUID=<UUID from before without quotes and brackets> /media/brian exfat permissions,auto 0 0

# Unmount your device
sudo umount /media/brian/Brian-HD

# Try mounting and troubleshoot
sudo mount /media/brian

 

The last step will work, but you might have to do some troubleshooting to make sure the format type is right and the mount location is correct.

Factory Resetting Nexlux LED Light Strip

TNexlux LED Light Strip Boxhe Nexlux LED Strip Lights sold on Amazon have a confusing set of “How to restore factory settings?” instructions

First, to add a device, install their app (Magic Home Pro app on Google Play or Magic Home WiFi on App Store) and click “Add Device”.

But if you already have a device and changed Wi-Fi networks, you will need to reset that device.

Repeat four times unless the device strobes multiple colors:

  1. Plug into power. With remote, turn on lights. Wait a few seconds.
  2. Unplug from power! (Not turning off with remote.) Wait a few seconds.

Google Location Sharing Review

Google’s version of Apple’s Find My Friend is Google Location Sharing. You can set this up to share your location with friends for a limited amount of time, or you can set it to always share your location with family (or friends). This helps them know where you are and hopefully make sure everyone is safe.

It works on Android and iOS, though on iOS, you need to allow Google to have background access to location services. Otherwise, the location updates will only be since you last opened a Google App on iOS.

I have not experienced any additional battery drain. If you use Google Location History, it is already saving and reporting your location to Google. So, this is just allowing your family member to view you using data your phone is already reporting.

In my usage, updates are between 2-30 minutes, but you can always ask it to refresh, which seems to pull a newer location, but I am not sure what it is exactly doing.

What are the alternatives? The best would be Glympse, which has more features for short-term sharing. It lets you pick a destination, showing your friend where you were, where you are going, and the ETA to get there.

Secure Messaging Apps Review

oblivate Review

Makeusof.com released their own security app called oblivate, available on Android and iOS. Their announcement article was the typical propaganda saying the app has these features:

  • Message delete timers (“self-destructing”)
  • No screenshots (Android only)
  • No chat history
  • Free and no ads

But for a company to say an app is secure, as they are, the app should have at a minimum:

  • Encryption
  • Open-source or 3rd party auditing

And they do not. (They do not even have picture support!)

Coming soon, obliviate hopes to add encryption, support for audio, pictures, and videos, custom notification sounds, and more! We hope you enjoy the app.

Overview of All Secure Messaging Apps

This is a problem amongst the secure messaging app space, they all have security tradeoffs:

  • iOS stores your private keys in their servers.
  • Telegram uses its own encryption algorithm.
  • Wickr and this app are not open source.

Or usability tradeoffs:

  • Signal (Open Whisper System) is confusing to set up and limited users to talk to.

The best compromise out there is Whatsapp. It uses the best open source end-to-end framework, done by Open Whisper System. With end to end encryption, a government cannot force Whatsapp to give up your messages because Whatsapp cannot even see them! The one known security tradeoff is actually a feature – you can recover messages when you switch phones. This could be used by a government to get some of your recent messages. With that security flaw in mind, Whatsapp has a huge user base so you can talk to mostly anyone and the app is easy to use.

I suggest Whatsapp for normal, daily, secure messaging use.

[NO SOLUTION] Lenovo Thinkpad shuts down after exactly 30 minutes

I recently received a rather new Lenovo Thinkpad Ultrabook for free because the machine running Windows would shut down after 30 minutes exactly. It was running Windows and I thought it was a problem with Windows, well…

Installing Linux, it would shut down after 30 minutes exactly.

On AC, Battery, or AC with no battery, it shut down after 30 minutes exactly.

In just the BIOS screen (no Operating System loaded), it shut down after 30 minutes exactly.

Updating the BIOS to the latest version, it still shut down after 30 minutes.

Verdict – Hardware

There are many forums discussing this topic across Lenovo and some will say “[SOLVED]”, but that is just because the post became stale. From what I can see, there is no solution to this and trying to fix it will be a waste of time. I believe this is only affecting older laptops so if you are reading this, you are probably out of warranty. But if you are in warranty, return the laptop. If you are out of warrant, get a new laptop.

Do a Google search for Lenovo shutting down after 30 minutes. I went through mostly all of the results.

Saving Tree Style Tabs into Bookmarks with Firefox

On Firefox, my favorite add-on is Tree Style Tabs (download), because

  1. you can see all of your tabs and their names
  2. tabs have hierarchy (parent > children > grandchildren)

Once you use it, you will always want to use it, especially at work. But if you get the error message “failed to get permissions to create bookmarks“, you need to grant permissions to the add-on. This is not straightforward. The notification will probably be cutting off some of the words! But if you got here, this is how you do it.

Go to Add-ons > Extensions > Tree Style Tabs > more.

You should see this, so check the checkbox next to “Allow to create bookmarks”

additionalContext

You might get another error message! This is because this add-on’s preferences page cannot request access to the bookmarks. So, you now need to click on the add-on’s icon in your toolbar:

media-20180119

And follow the prompts there. The confirmation dialog will likely appear on the top left of your browser window!

NAT Loopback on Xfinity

The current Xfinity routers (end of 2017) do not support NAT Loopback and have no options for enabling NAT Loopback.

What is NAT Loopack?

NAT Loopback or Hairpinning is when Device_A behind a router tries to access another Device_B behind the same router by Device_B’s external name (e.g. domain name) instead of its local name (e.g. local IP address). Because of the way packets will leave the router and reenter, some routers disable NAT Loopback for security reasons.

Problem Description

When a router does not support NAT Loopback, a techie will have a problem if they are:

  • hosting a home server
  • using a domain name to route to the home server
  • accessing their home server via the domain name while on the same network as the home server

Partial Solutions

  1. While home, access the server using the local IP address.
  2. Use a VPN to route traffic out of your home, which will then go back home and to your server.
  3. Buy a router that supports NAT Loopback. [link_1]
  4.  Set up a local DNS server to change the public domain name to the local IP address.
