RUN TCP/IP | Morgan Lucas is Tech Blogging

The new CCNA was released in mid Feb of 2020. With the advent of COVID, all of our active certs were pushed back 6 months. Mine won't expire until the end of next year, which is rapidly approaching. So why not go through the free course on Cisco NetAcad? It looks way different than the first course. The navigation on the left starts at... 10. It takes until 11.1.10 to get to a Packet Tracer about Port Security. It's an old one, I recognize it. There are no small activities scattered throughout the (much shorter) lessons. There used to be matching games. Short quizzes are at the end of each section. (Unrelated note: It also showed that the Rogue Laptop thwarted by port security and sticky MACs, while in the same subnet as the legitimate machines, couldn't ping. Because port security!) The Syntax Checker displays the appropriate instruction at the appropriate time. No more continuous scrolling back and forth (Unless you want to go upward and check on a command in the lesson) ...

Like many events, CiscoLive 2020 was pushed to an all digital format. What is everyone talking about? I'm at #CiscoLive with a crowd right now! 🎉 pic.twitter.com/djamyEymyG — Morgan Lucas @ Cisco Live! ※ o(￣▽￣)ｄ (@runtcpip) June 17, 2020 So, I have to repeat this again; Online events should have always been an option at this point . I understand the energy of real people. It's fun to talk to random, like minded people! However, these events take place in a world of growing inequality, especially in America, where people who want to learn, network , and improve, might not have the money for this.

Let's briefly look at some virtual firewalls in Linux. This is Iptables, running in my Ubuntu Server. Remember that? What is CHAIN in this context? My best guess is 'the route a packet takes'. Think "At this point in the process, what should happen to this packet?" [ 1 ] Here, it's saying "Forward everything!". At which point, you may as well not have a firewall at all. So let's set some rules on this bad boy;

I browse websites and apps, while making note of things I find frustrating for end users. You have probably been linked here from a form or my resume. If you have any questions about what I'm looking for in a role, click here .   This post is not to shame, but to point out errors and hopefully make my talent for finding and documenting such mistakes clear to someone hiring. Contents: Instances where I offer constructive feedback on someone's website, logo, or app. Actions that were taken by the developers or artists.  I'm glad you want your webpages to be the best they can be with my help; If you need your sites audited, e-mail me .

Back in times of old, when we could go places, one of those places was the movie theater. The smelly, cramped, outdated movie theater. One of those movies to be played in the theater was Disney's "Artemis Fowl". When worldwide hell broke loose, it was banished to Disney+. I have waited too long to see it - More than 15 years - And won't be deterred by watching it upon a smaller screen. Before we can get to that story, let's peel away the application layer tech and take a look under the hood. I think ,even before COVID-19, that this was headed to a digital grave.

The course is in 6 sections, so I'll separate them by parts. I do have Windows Server experience, and 2019 is new to me, though the general idea is the same. 💠 Powershell is A) A scripting language, and B) Is an application with a command based shell to run and create your own Powershell scripts and modules (a collection of scripts, modules, and functions). 💠 PowerShellGit is used to download packages from GitHub. Is it the equivalent of 'apt-get'? 💠 You can remote the Domain Controller from Powershell. Consider the permissions, who is logged into the target machine. Other parameters may be needed. 💠 Invoke-Command -ScriptBlock {cmdlets} -ComputerNames("name1", "name2") can be used to run the same command on multiple domain controllers and servers. 💠 Windows Admin Center is a browser-based app for managing clusters, servers, and Windows 10 PCs. Check your SSL certificates! 💠 When installing a role or a feature, you're prompted to install GUI ...

Again; I've done this, but now there's so many new things, I'm doing it again. The truly new portions were...everything on the right side of this diagram; The cloud needed a coax connector and a copper Ethernet connector. It's all easy to install, turn off the cloud (Weird), install the modules. Getting the Cable section of Connections was an unusual struggle - The other drop down menu had nothing within. It required going into the Ethernet options and setting the Provider Network to 'cable', which is the next step AFTER the drop-downs. The rest was typical DHCP and DNS setups, mainly on the Cisco server down there. The post is rather short - How about adding a video to it? Find out what A Record means - This site says 'Maps a name to an IP address', which is DNS. So it's another name for DNS? You can change them (presumably in a local context) to associate an IP address to another name.
