SmartRG router cheatsheet

The SmartRG router (supplied by Sonic ISP) has a bad user interface. There is no easy mode, just very network centric terminology to maneuver. 

Local Server Walk-through

Let’s say you plug in your laptop to Ethernet or connect to the Wi-Fi. First, go to the “Connected Devices” section and get your IP address and MAC address. Second, go to “Static IPs” and add to the Static IP Lease an entry for your MAC address and IP address (you can change the IP address if you want, but you have to restart your device). Third, go to “Port Forwarding” and forward ports to the IP address, like 22 for SSH or 80 for HTTP. Lastly, if your device is using a domain name, you can add a “Static DNS” route so you can reference your laptop within your local network (this solves the problem of NAT loopback).

SmartRG network hard drive – SAMBA version too old

The SmartRG router (supplied by Sonic ISP) has the option of mounting a hard drive for access by all computers on the network via the SAMBA protocol. But the SmartRG router supplied has an old version of the SAMBA protocol, that Windows 10 will not use due to major security vulnerabilities with it. Getting a firmware upgrade for the router is not easy on their SmartRG website, but teksavvy.com has a firmware upgrade that can be used. But again, an old SAMBA protocol is used, so Windows 10 will not connect to the networked hard drive.

Sharing the Hard Drive to just be denied

If you want to go ahead and still try to access the hard drive, follow these instructions with the following modifications/highlights:

  • SmartRG’s device configurations are located under: Advanced Setup > Storage Service > Storage Device Info
  • On the router, give the device a name in this menu
  • In Windows, you will be Mapping a Network Drive
  • This will be your address: \\192.168.1.42\given-name
  • When prompted for a password, use the admin password for your router

Nextcloud on AWS with S3 and Lightsail

Running a Nextcloud instance in AWS rather than at your home has some benefits:

  • S3 storage means unlimited storage
  • Static IP
  • Fast bandwidth
  • Always able to SSH into machine and restart it

I suggest this blog that provides a few steps to get you up and running in less than 15 minutes, along with getting a free domain name at dot.tk.

To avoid:

  • Do not use Amazon Linux
  • Do not use encryption (my server stopped being able to retrieve files)

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.
