Network migration complete

The migration to AT&T fiber is now complete and everything went very well. Of course that is not to say it was problem-free.

I have never been a fan of AT&T but my previous provider has been unable to resolve issues with the network just dropping out and the modem/router rebooting at frequent and inopportune times. But the speed of fiber and the fact that it is symmetric with upload and download speeds at 1Gb rather than uploads being so much slower as wih my old provider, and the fact that it is significantly less expensive, I decided to switch.

I wanted to go with residential service which is much less expensive but I had some concerns about needing static IP addresses and with issues I have seen with blocked ports like 25 for email. I run my own web and email servers so that was important to me. After a chat session with a fairly knowledgeable rep and talking with a sales person on the phone, they both said that the static IP addresses were not a problem and that the installation tech could help set that up as well as deal with blocked ports.

They were right. Which was a surprise to me.

Scott, the installation tech called me the morning of the installation to let me know he was on the way and he was delayed only slightly due to traffic. We discussed my needs for a few minutes and he assured me that we could do exactly what I needed. As a gamer, he was very knowledgeable and understood what I wanted and why.

After doing the physical installation of running the fiber from the street to my home office, we worked together to install the modem/router in my desired location and get it and the ONT plugged into a UPS, cabled together, and connected to the fiber. I would not let him into the narrow space available to do that so we worked together on it.

He installed updates to the Arris modem/router and we were ready to go. He showed my on his hand-held tester that the rates were both within a decimal point of 1Gb. We easily got the static IP addresses configured on the router.

I then reconfigured my own internal router. We did have some issues with blocked ports. Although I could browse the web and SSH to remote hosts, nothing was able to initiate connections to my router/firewall. After calling around to various support systems inside AT&T, Sctt and I figured out how to unblock the needed ports and everything was working fine.

I did have some issues with speeds, but those problems were with my own older Linux computer that I was using for my router/firewall. I moved the hard drive from that machine to a newer one, installed the needed network adapters, made a few configuration changes and all is now well.

It just took longer than I expected but everything seems to be working very well now. Thanks for your patience and I hope you were not inconvenienced by the outages during this time.

Network migration Monday, January 20

Outages through Monday

Due to a large number of intermittent outages with my current internet provider, I have decided to move to a new provider. These outages make access to my web sites with their information about my books, unavailable at random times. Please keep trying if you have problems and you should ultimately get through. The outages last several minutes at a time. This problem also delays both inbound and outbound emails.

The intermittent outages will continue though the weekend and there will be a fairly long outage of several hours on Monday as the new service is installed and I get DNS updated.

Thanks for your patience.

Site outages today

This web site has been experiencing random outages caused by apparent random power supply failures. Unfortunately I do not have a suitable spare, which I normally keep, so I will need to purchase a power supply. I will have it replaced by early afternoon but if you have tried this site and not been able to access it before then, I apologize.

Thanks for your patience.

Update on BookAuthority

After some additional research, it turns out that BookAuthority is merely an Amazon “partner.” They advertise Amazon books and get a bit of money from Amazon for doing so. As near as I can tell, they create these “top X” categories and use that to attract potential purchasers whom they hope will click through and purchase from Amazon. They also provide meaningless graphics for us authors to place on our web sites to generate traffic to their web site.

They claim on their web site that the “ratings” they give each book are calculated using a “proprietary algorithm” from publicly available data. Whatever. This seems to be a way to prevent authors and purchasers from finding out how they really work.

I do not believe that they have any relationship with the people they claim recommend the books they list. That is not to say that those people don’t recommend those books, just that the don’t do it “for” this organization.

So my conclusion is that being on any of their lists is bogus and meaningless in terms of the value of my books. Such value would be impossible to determine because not one of the three volumes in my “Using and Administering Linux: Zero to SysAdmin” series was available as of this writing so no sales figures could possibly be available then.

You will need to determine for yourself whether my books are of any value to you or not. If you do find that they have some value – after you purchase and use them to learn how to be a Linux SysAdmin, please leave a legitimate review on Amazon, Barnes and Noble, or GoodReads. Thank you!

However, with all that said, it really did boost traffic on my personal web site considerably when I posted the article yesterday.

Outage fixed

A few days ago we had an outage on this web site that lasted from Monday through Wednesday night. This has – obviously – now been fixed and we are back up and running.

The problem appears to have been a surge from a nearby lightning strike that somehow powered off the server. This was not a power failure and there are no indications of that on any of my UPS systems.

Because I was out of town and this required a physical intervention I was unable to resolve it until Wednesday night. It only took a few minutes once I was able to restart the server.

In any event all is well now.

Status update

I have been too busy to keep this web site up to date with the latest information I have gleaned from my experiments and experiences with Linux. This has mostly been due to the work on my book projects over the last couple years which have taken up almost all of my time.

The good news is that I am working on the last few chapters of my current book project, after which I will return to keeping this web site more up to date. I have plans to add new content as well as move some of the older and less relevant content to an archive section.

Please bear with me and be patient. I have much interesting new stuff to add here as soon as work on my books tapers off.

My next book: Using and Administering Linux

From Zero to Linux SysAdmin Self-Study – Book 1

My next book is a self study course, “Using and Administering Linux – From Zero to Linux SysAdmin Self-Study – Book 1.” It is set to be published by Apress in 2020. I do not yet know the exact date, but it should be early in the year. As you can tell from the title, another book will follow soon after.

About the book

Become a Linux sysadmin and expert user of Linux, even with no previous Linux experience and learn to manage complex systems with ease. This book provides you with the tools necessary for mastering user management; installing, updating, and deleting software; creating and managing simple firewalls; and using command line tools to do performance tuning and basic problem determination.

You’ll begin by installing a Linux instance on a VirtualBox VM on an existing Windows or Linux computer that can be used for all your projects. You will then move on to the basics of using the Xfce GUI desktop and the many options Linux provides for working on the command line including virtual consoles, various terminal emulators, BASH, and other shells. Some of the more advanced user level tasks include creating, deleting and managing files and directories, managing the users own processes, writing short command line programs, and creating shell scripts to begin learning how to “Automate Everything.” 

Improving efficiency using command line recall and editing, command line history, and by creating command line aliases is addressed as well. You’ll configure your own BASH environment by directly editing the user level BASH configuration files, and learning the Vi editor in the process. Using and Administering Linux, the first book in the From Zero to SysAdmin series will help in using and managing Linux client services, such as DHCP network configuration, Chrony, SSH, DNS name services, and more. 

What You Will Learn

  • Install Fedora Linux and some basic configuration of the Xfce desktop
  • Access the root user ID, and the care that must be taken when working as root
  • Explore administrative tools available to root that enable the student to manage users, filesystems, processes, and basic network communications
  • Configure the boot and startup sequences, start, stop, and obtain the status of running services
  • Review methods of performing and testing backups.

Who This Book Is For

Anyone who wants to learn Linux as an advanced user and system administrator at both the command line and the GUI desktop. 

Details

The ISBN number for this book will be ISBN 978-1-4842-5049-5. The estimated cost is $39.99US.

Thanks.

Hardcopy of “The Linux Philosophy for SysAdmins” now available

The hard copies of my book, The Linux Philosophy for SysAdmins, are now available at Apress and on-line at Barnes & Noble but not yet at Amazon. Amazon is showing availability in February of 2019 but I think it will actually be available sooner.

This is all quite exciting for me as an author. I wrote a couple chapters for a book on OS/2 many years ago, and I have written for various publications such as Linux Journal, Linux Magazine, and Opensource.com but having my own book published is amazing.

I am looking forward to your feedback. I hope you will purchase my book, if you haven’t already, and leave a review on Amazon, Barnes & Noble, or Goodreads. If you may email me directly at LinuxGeek46@both.org with direct feedback such as errors and typos. If I do not respond, it may be because my server has blocked your email for some reason so contact me on Twitter @LinuxGeek46 and let me know of the problem so I can whitelist you.

Thank you!
