Computer Log

Just for my information I configured Cisco 2501 routers at the bank, in mid 1996. They stopped selling them in 2002.

Glad I switched years ago.

Spotted this duplicate file remover on my system. It’s version 0.4.2. So I deleted it after going to website and finding the latest version is 3.0 and if yo click download it only offers an .exe. Also it’s a flatpak.

Just watched a Chris Titus Tech video about Quickemu. Looks very cool to rapidly deploy various OSs.

I installed the Brave browser maybe a week ago, and it reminded me of why I dislike chrome which it was obvious to me that it is based on. And it has to do with a bad habit I have of keeping too many tabs open. In Firefox the tabs mostly stay the same size. There are scroll left/right buttons to see the other tabs that don’t fit on the screen. However these Chrome based browsers attempt to keep all the tabs on the screen. So the tabs keep getting smaller so more will fit until the point where you have no idea what a tab is.

Been getting a lot of emails from Amazon that say “We found something we think you might like”. Then they proceed to show me something on one of my Amazon list. Gee..how’d they guess?

However I have a specific Soundcore bluetooth speaker on one of those lists and they continuously offer me a deal on every model except that one.

Yes it was…today!

Pretty much followed this. Setting it to run without sudo which is recommended. Couldn’t remember how enable after adding my user so rebooted…logout and back on not good enough.

Here is the start screen (not run as sudo) as proof since Gambas mysteriously disappeared.

The top interfaces wouldn’t show without sudo unless you set it to run without sudo. The bottom shows the version 3.6.7.

I saw a Udemy course that sparked all kinds of ideas…Get Hands-On Practice Building your Own Networking Lab. This course uses virtualization to create a network. In the past I was solely using virtualization to test other Linux distributions. I rarely do that these days. But this may give me a more practical use of virtualization.

I might have to look back but I think I remember Noah Chelliah (of the Ask Noah podcast) talking about a cool network learning tool. I couldn’t remember it’s name however in looking at the course description I saw mention of GNS3, after googling, I’m sure that’s it! One big downside of the course for me, is a Windows computer (preferably Windows 10) requirement, and lot of it revolves around MS-Windows. The course is $90 but if it goes on one of Udemy’s many sales it might be worth $15 or $20 to get some ideas. I might be able to adapt it to work with Linux. Just a thought at this point.

On the other hand this video gave me an idea to search YouTube for Building your Own Networking Lab, and some results were shown. And this further caused me to search YouTube for GNS3 where I saw GNS3: Start here if you are new to GNS3 by the instructor of one of Udemy’s Wireshark courses. So the Title and course description alone has given me many ideas. Oh the possibilities!

I noticed Udemy offers some Wireshark courses. Definitely want to look into those. Many many years ago I was trained to configure Cisco routers for all the bank branches at a bank I worked for. I was sent to Cisco configuration school. However I remember very little about it. Cisco engineers came in at the beginning to help us get started. I remember they had a network protocol analyzer, that I’m guessing were probably proprietary. I would look at this strange network gibberish on the screen that the engineer understood. Since then I’ve always wanted to know more about networking. This was the late 1990s. According to Wikipedia Wireshark’s Initial release was 1998. Wireshark’s about page says…Wireshark is the world’s foremost and widely-used network protocol analyzer.

Side note: I also installed Suse Linux that I bought at CompUSA (now defunct) and ran software called MRTG (Multi Router Traffic Grapher. I would have never have remembered that name if it wasn’t for a log-file I kept) that would show network traffic in these very nice graphs in almost realtime. I probably have some examples somewhere. These graphs that I could pull up for any branch were very cool looking for the late 1990.
