Changing the DNS Provider on Your iOS Device

Tech Tip – Generally we all just let the network provider designate our DNS provider. You may want to change that and choose Quad9 for improved security, performance, and privacy for your iOS device. See that link for the story behind Quad9.

Changing the DNS provider on your iOS device is simple. Open Settings ==> WiFi.

Click on the blue ‘i’ next to your selected WiFi network.

IMG_1847

Under the DNS heading click on ‘Automatic’ to the right of ‘Configure DNS’

Change the setting to Manual, then click on the ‘Add Server’ under ‘DNS Servers’ and enter the IP address of 9.9.9.9, then delete the others. Save your changes.

Now you are all set up to use the Quad9 DNS servers.

Unfortunately, you need to make this DNS change individually for every WiFi network you use. I am slowly updating both my iPhone and iPad to use Quad9 on each of the WiFi networks I use.

Quad 9, a Better Choice For Your DNS

Tech Tip – As you know if you follow my posts, I listen to a lot of podcasts. While nearly it is nearly 10 months old (I have quite a podcast episode backlog), I listened to episode #638 of the Security Now podcast as I went on a walk earlier today. The primary subject of this podcast was Quad9.

So what is Quad9? From their web page:

Quad9 is a free, recursive, anycast DNS platform that provides end users robust security protections, high-performance, and privacy.

Why would you want to switch to Quad9? The video above gives a short (2:29) overview of how DNS works to resolve Domain Names into IP addresses, and how Quad9 can provide you with more protection. The Quad9 claims:

  • Quad9 blocks against known malicious domains, preventing your computers and IoT devices from connecting to malware or phishing sites (Quad9 pulls in security intelligence from 19 partners including: IBM’s X-Force, Abuse.ch, the Anti-Phishing Working Group, Bambenek Consulting, F-Secure, Netlab, and Proofpoint)
  • Quad9 systems are distributed worldwide for quick response with servers in more than 128 locations at present. More than 150 locations in total are scheduled for 2018 (published tests demonstrate Quad9’s response time [1,5,7,8])
  • No personally-identifiable information is collected by the system [4]

The founders of Quad9 include IBM, PCH (Packet Clearing House), and the Global Cyber Alliance (GCA). Quad9 works with several partnering groups to make Quad9 a safer, more secure and private way to do DNS lookup. While they have extensive tech in place to block malware domains, Quad9 also has whitelisting in place to prevent known valid domains from being accidentally blocked [1,4].

After listening to Steve Gibson talk about Quad9 on Security Now I decided to switch to Quad9. Shortly after I returned to my apartment I logged on to my MacBook and set up Quad9. If you are not sure how to change your DNS provider on your Mac, the video above shows you how.

You should make the change to Quad9 on your Mac too! You can also set the DNS on your iOS device.

macOS New App Release – My IP 2.3

Product AnnouncementsTension Software of Milano, Italy has released My IP 2.3 for macOS, a utility app to see with which public IP address you are connected to the net (different from your IP address inside your LAN). It can work also in background and can optionally show the current IP in the menu bar.

The public IP is the IP address you use to connect to the global net, the address the rest of the world see you at. The public IP address sometimes can be static (always the same), sometimes dynamic (changed by the internet provider over time at any connection).

Obtaining the IP value of your connection could be not easy, particularly if you are behind a modem router. In the case you are using a modem router, using normal system utilities, your IP address will be indicated as equal to your LAN (Local Area Network) IP address, with is really just your address inside your local network, totally different from your true external public IP address on the internet.
Your internal IP address has no value outside your local area network.

My IP works instead indicating always your true internet IP address, the one the world can see you at, detecting the IP address your modem router uses to connect with the rest of the world, with is the address the rest of the world identify you and can use to connect to you.

Knowing your true public IP address is mandatory in many situations where you have to specify, especially for external use, at which address you are and can be reached by servers or desktops outside of your LAN.

My IP offers a simple and intuitive interface, a fast use and the option to work with 4 different servers to show your public IP address. It can optionally display the IP in the menu bar also when in the background and log the IP changes on disk. The log can be rewetted at any time.

Features:

  • Fast and easy to use
  • Useful to know your public IP address behind a modem router with a shared IP
  • Able to show your public IP where usually system utility fails showing just your LAN IP
  • Instant result available at launch
  • Can use 4 different servers to calculate your public IP
  • Can log the IP and its changes on a log on disk
  • Can optionally display in the menu bar the current Ip also when in background
  • Copy the IP from within other applications from the menu bar.
  • Includes embedded PDF User Guide
  • Has a similar native version for the iPhone , ‘My Public IP’ available on iTunes

New in this release:

  • Layout and Interface Update
  • Possibility to use a shorter check IP interval (from 5 seconds to 59:59)
  • Bug fixes
  • Various Optimization

System Requirements:

  • macOS
  • 1.6 MB

Pricing and Availability:
My IP 2.3 is just $2.99 USD (or an equivalent amount in other currencies) and is available worldwide through the Mac App Store in the Utilities category.

643x0w

Product Announcement – Sentry Secure Communication of Los Angeles, California has released SkyVPN 1.0.5, a maintenance update to their popular private network application service for macOS. SkyVPN is known around the world for effectively bypassing emergent firewall blocks. But up until recently, it was only available on Android and iOS. Now, Mac users can get the same VPN service with the newly-released SkyVPN for Mac.

Have multiple devices on different operating systems? No problem. SkyVPN users can use the same VPN account on any device running iOS, Android, PC or Mac, at the same time. Most importantly, there is no limit on traffic consumption.

What’s Special About SkyVPN?
The VPN service market has exploded in the past few years and there are now a large number of VPN apps available. But SkyVPN is special. What makes SkyVPN different from all the other VPN apps?

SkyVPN is the only VPN app that provides free Premium service. At sign-up, users can take advantage of two different kinds of service:
1. Basic Service (free, US server only)

Pricing and Availability:
SkyVPN 1.0.5 is Free and available worldwide exclusively through the Mac App Store in the Productivity category.

macOS New App Release – Beyond

Product AnnouncementsMiln of Allier, Auvergne, France has released Beyond, their new app that makes it easy to run a web server on macOS. Every Beyond document is a web server. Opening and closing a document starts and stops a web server. As a true Mac app, Beyond is built around a modern document based architecture. Beyond supports AppleScript, Automator, drag and drop, undo and redo, and everything users expect from a macOS application.

Beyond is secure web server suitable for new users. The application and the web servers are sandboxed. Each web server is independent and can only serve files from the folder selected by the user. The server can not write files or execute scripts.

“I created Beyond because I wanted a fast way to test websites on my own Mac,” said Graham Miln. “Once I had proved the secure architecture, I could see the path from serving just my Mac to serving on the Internet was possible but not easy. It took more work than expected but Beyond can now map ports, ensure reachability, and get a domain name, all without needing the user to wade into a technical quagmire. The simple interface protects you from the complexity.”

Beyond’s web server requires little memory and processing power. Each server’s memory requirement is measured in tens of megabytes. A small web site will require only a few megabytes of memory. This makes Beyond suitable for running multiple servers on any Mac computer.

Beyond is ideal for users who need to develop, demonstrate, and test websites locally. Modern web development requires loading web pages from a server. Web browsers, such as Safari, show different behaviors when loading files from disk compared to a server. Using Beyond helps users run a server and see the final behavior without any complex set-up.

Miln offers a pay-for Beyond Membership. Membership expands the technical options available within the application. These options include control over the local TCP/IP port, the mapped port via NAT/UPnP, and passphrase protection to secure the served site.

Membership also includes the use of Miln’s reachability and domain name service. Running Beyond on a Mac is enough to serve computers on the same network. Reaching a wider audience, those on the Internet requires help from outside of the local network.

Beyond members gain access to Miln’s reachability service. This service actively tests each potential network address on your Mac for global reachability. This test involves checking both inbound and outbound traffic, on both IPv4 and IPv6 networks. This real-world test means users know which addresses are truly public and which are not. This information is displayed in the Beyond Network window of the application.

Once Beyond members have reachable servers, Miln provides a domain name as part of the membership. A domain name is assigned automatically for the Beyond user and is available globally. Members can use the friendly domain name to access and share their web server. Beyond domain names support both IPv4 A records and IPv6 AAAA DNS records, as appropriate.

Beyond provides a simple, secure, and free, macOS web server.

Beyond Membership makes the step from running a server on your Mac to serving the world, trivial.

System Requirements:

  • Mac OS X 10.13 or later
  • 7.6 MB

Beyond is free and is available worldwide through the Mac App Store in the Utilities category. A Beyond Membership is required to access advanced options, use the reachability service, and be automatically assigned a domain name. 1 year : 16.99 EUR / USD, 3 months : 6.99 EUR / USD Beyond Membership does not auto-renew. Access to the options and services ends when the membership period ends.

How to Remotely Access Your Mac – Part 3

Product Review – In the prior articles of this series I described in “How to Remotely Access Your Mac – Part 1” how you can access your Desktop Mac from a MacBook when they are both on the same network and in “How to Remotely Access Your Mac – Part 2” I outlined how you might be able to use Back to My Mac to access your Mac from a remote network. But Back to My Mac does not work for everyone. There is an easier solution though – “TeamViewer“.

TeamViewer is a third party solution with the parent company having been launched in 2005. The focus of the product is to provide online support and collaboration. Some of the statistics claimed on the website for TeamViewer:

  • has been installed on over 1 billion devices (each device generates a unique ID)
  • creates 750,000 new IDs every day.
  • has over 20 million devices online at any given time
  • speaks your language with the software and support in more than 30 languages
  • 90% of Fortune 500 companies rely on TeamViewer to bring colleagues together across all platforms and all devices

TeamViewer IS a commercial product:

  • Single user business license $49/month
  • Multi-User Premium license $99/month
  • Corporate Team license $199/month

 

Screen Shot 2018-03-05 at 4.50.25 PM

HOWEVER, it is completely free for personal (computers and devices that are not being used for business or other commercial tasks) use. Per their website:

100% FREE for personal users! If you’re a student or are using TeamViewer to help friends and family, it’s completely free FOREVER. You’ll never be charged.

Screen Shot 2018-03-05 at 4.49.49 PM

To install, go the website and click on the TeamViewer 13 Download button. This will download the TeamViewer DMG file onto your Mac. Double click on the DMG file to mount the volume. Then simply double click on the icon in the window to install the package on your Mac and follow the provided instructions.

To make my discussion a little easier I will henceforth call the Mac I want to remotely access the ‘server’ and the Mac I want to access it from as the ‘client’. You have to install TeamViewer on both the remote ‘server’ and the local ‘client’ Mac.

Screen Shot 2018-04-17 at 12.36.40 PM Screen Shot 2018-04-30 at 5.27.02 PM

Once you have TeamViewer installed and running on the ‘server’ Mac, a blue icon will appear in the Menu bar. To set the Mac up for remote access, click on the icon and a drop-down menu will appear. Click on the “Setup unattended access.”

Screen Shot 2018-04-30 at 5.29.52 PM

Use the resulting panel to set the name and a password for remote access on the ‘server’ Mac. Make the password something you will remember or write it down in a secure location. You will need this when you attempt to access the ‘server’ Mac remotely.

Screen Shot 2018-04-30 at 5.32.18 PM

Now click on the TeamViewer icon again and select “Show TeamViewer” from the drop-down menu. In the column headed “Allow Remote Control” will be the ID for the ‘server’ Mac. For me, this is a nine-digit number similar to “123 456 789”. Write this down as you will need it when you attempt to access the ‘server’ Mac.

Now install TeamViewer on the ‘client’ Mac and run it. Click on the TeamViewer icon in the Menu bar. In the “Control Remote Computer” column enter the ID of the ‘server’ in the “Partner ID” field. Leave the selection as “Remote Control”. Now click on the “CONNECT” button to connect to the ‘server’ Mac. When prompted, enter the password you set up on the ‘server’ Mac for unattended access.

A window will open with the login screen for the ‘server’ Mac. You can then access the ‘server’ as if you were sitting at its keyboard.

If you are going to use TeamViewer I would suggest that you set up both the ‘server’ and ‘client’, then verify that the remote connection works while you have physical access to both. It is much easier to work out problems when you have both machines in front of you.

I have used TeamViewer a few times now to access the Mac Mini in my office in Round Rock, Texas from Henderson, Nevada. While it isn’t as efficient as being there, I can certainly access the data stored on the Mac and run Apps.

Having used it now a few times, I would consider TeamViewer a requirement for my Mac Toolbox on both my home desktop and my MacBook.

 

Pros

  1. Free for personal use
  2. Gives you complete access to your remote Mac

 

Cons

  1. Depending upon connection bandwidth, the response can be ‘laggy’
  2. Depending upon connection bandwidth, the image in the ‘server’ window can pixelate
  3. Third-party software

Product Review of TripMode

TripMode2-Sierra-Background

Product Review – I had read about TripMode, but it was a discussion of it as a recommended utility on the Mac Power Users podcast #386 Must Have Utilities that convinced me to purchase it. TripMode is a Mac utility that allows you to (per their website) “Easily block unwanted apps from accessing the Internet the second you connect to a hotspot“.

The utility is very useful when you are operating your MacBook over a hotspot instead of WiFi (IEEE 802.11). As I have found while traveling, there are many Mac software packages that are constantly trying to use the Internet. If you have a limited monthly data allocation for your hotspot device, you can very quickly find it used up in just a few days. I recently found that I had used 90% of my monthly 15G allowance in just six days! While my connectivity doesn’t end when I hit the 15G limit, my access speed is severely constrained.

TripMode seems to be the answer. I purchased ($7.99 from their website) it yesterday and put it to work on my MacBook. With TripMode in place, I was able to both monitor and control my data usage.

Screen Shot 2018-04-25 at 11.54.50 AM

Data monitoring is an option not enabled by default, but I wanted to see how much the various applications were using so I enabled it through the TripMode settings.

Screen Shot 2018-04-25 at 11.55.24 AM

You can create as many profiles as you like, giving each a separate name. You have can then choose which Apps are allowed to access the Internet in the profile by checking those you want in the list (Safari is selected in the image above).

Screen Shot 2018-04-25 at 12.00.03 PM

TripMode shows up in the Menubar at the top of your screen. The icon blinks red every time an App attempts to access the Internet and is blocked. When the TripMode icon is clicked you get a drop-down list of the Apps with an indication of which are enabled in the current profile and their data usage. This drop-down also lets you switch between profiles (the profile currently in use in the image above is ‘writing’.

You can set up the usage monitoring to start on any day of the month and to last for periods of a single day, a week or a month. Using TripMode I have been able to keep working over my hotspot, yet limit which Apps are using the limited resource. TripMode remembers which WiFi access points it has been turned on for in the past and automatically activates when one of those access points is used in the future.

Now that I have used this App, I consider it a must-have App for my MacBook. If you ever use a hotspot while traveling, this is an App you need to consider.

 

Pros

  • Easy to install and configure
  • Multiple profiles user definable
  • Profiles for different operating situations
  • TripMode starts as soon as you connect to Wifi
  • Vendor claims there is no tracking of Internet sites visited
  • An abbreviated user manual is available through the App

 

Cons

  • The $7.99 seemed a little high, but it was worth it
  • No indication of which App is being blocked when the icon flashes red

Review of “Direct Fire”

51ZnOVmmezL._SY346_

Book Reviews – “Direct Fire” eBook was published in 2017 and was written by A. J. Tata (https://www.ajtata.com). Mr. Tata has published nine novels. This is the fourth in his “Jake Mahegan Thriller” series.

I received an ARC of this novel through https://www.netgalley.com in return for a fair and honest review. I categorize this novel as ‘R’ because it contains scenes of Violence. The story is set in the contemporary US. The primary character is Jake Mahegan.

Mahegan received a call to meet with General Savage. When he arrives he runs into an ambush. At essentially the same time military leaders are under attack. This is the start of a full assault by terrorist agents in the US. Mahegan outwits those sent to kill him and begins a mission to find those behind the assault.

Complicating matters, the terrorists frame him for the attack on one of the military leaders. Ducking the authorities, he pursues leads that will take him to those behind the attacks. He must overcome many obstacles to stop the terrorists before they let loose even more destruction on the US.

I enjoyed the time I spent reading the 353 page thriller. I have read other novels in this series and enjoyed them all. I like the Mahegan character Tata has created for this series. The cover art is OK but doesn’t directly relate to the story. I give this novel a 4 out of 5.

My book reviews are also published on Goodreads (https://www.goodreads.com/user/show/31181778-john-purvis).
