RUN TCP/IP | Morgan Lucas is Tech Blogging

  There is a general recap by the good sir John Saville over here . That's how I found out about it! I'm more interested in seeing what it can do for my 5- year old refurbished laptop, a laptop I cannot hold too firmly on the left side or the Intel Sound Service cuts off. I had already hit "Boost" before this screenshot - my Memory Usage was at 73%, and now it's at 67-68%. I hit it again and it goes down to about 58% - 63% If I take the time to boost this about once every 5 minutes, boy howdy, we'll be on a roll. I do know it's Firefox that takes up a lot of the memory for some reason. I should do an audit on that. You may have noticed that Smart Boost button, which I did follow and turn on; I wish I could drill down and tell it exactly when to boost, preferably at 70% Memory Usage. Process management is basically a prettier Task Manager; Real Windows users know! Let's see what the PC Manager Health check can do. You'll notice the startup apps to d...

  alt: Three panels of a dog with a toy. Panel 1: 'Pls release IP address'. Panel 2: 'No release', Panel 3: 'Only hold onto expired IP' It's not practical for home internet services to let end users distribute their own IP addresses to their devices. The option is there, but it's far easier to let people use DHCP - You get a pool of addresses for your devices, and the router does the work in distributing them. That way, your devices can talk to each other (Somewhat - in a L2 network, they don’t need IP addresses) and reach the internet! But what happens when one Windows 10 device is unused for months? The device is totally off. It holds onto an expired IP address - and then it can't get back on. That's what happened this week. After scanning with Wireshark, no DHCP packets were being sent at all. The laptop didn't want to connect to any home internet router, of which there were two - The main one and the extender. Flushing DHCP didn...

 You may have no need to use Paint 3D, pre-installed software on Windows 10, for any reason than to have fun. And that's reason enough. Here for a fun time, not a long time.

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 ...

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. The first relevant video opens with " I was speaking recently with a network administrator for a global company. He told me that his IT infrastructure was out of date because his Windows Servers were a version or two behind the newest thing from Microsoft." Just because you can upgrade doesn't mean you should! If your stuff works (well), it works. If new features help your business, or have the possibility for your business to 'grow' into them then sure, upgrade. But there's no need to keep up with the Jones or Gates.

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. ✅  Active Directory Domain Services Schema (ADDSS) defines type of objects stored, properties maintained, and how these different bits of data relate to each other. ✅ Active Directory sites/domain/forests have names that aren't an option to change in configuration. In the Sites and Services name, you should change it (Right click it). Name it depending on geographic location. ✅ Link Values are set based on speed or bandwidth. Now we get into path costs and hops, and that's what I was trained in. ✅ Encryption of traffic between VMs on a per-subnet basis! Use Certificates on Hyper-V hosts. Everyone gets a matching certificate Virtual machines/switches are created and managed by network controller. Reminds me somewhat of CHAP and PAP . ✅ Cluster Sets have consistent hardware and shared namespace. They help with high a...

It's an executable, not a full-fledged program intended to replace your Anti-virus software. It self-destructs* after 10 days unused from the download. *Maybe not self destruct, but it will render itself inoperable. Threats change all the time, even 10 days could make it outdated! It took quite a long time, and slowed my PC to a crawl. Best to use it overnight, if possible. It concluded, and listed the removed software. You can download the latest version here .

So, here's a tool I didn't know about until now ("now" being when I initially wrote this post in...October?). Windows Reliability Monitor; You can find it by searching (Click the Windows icon and just start typing!) There are no errors between May 2019 and September 1st 2019: I did not get this laptop until July 2019, and it was refurbished. So, either the monitor doesn't go back more than 5 months, or this machine was returned and wiped and sat in storage for months until I bought it. The numbers on the far left indicate a health score - 10 is best. The problems make the score start at 5.  An update between September 1st and 15th caused some things to not update, including an Intel driver, but we're all good now . You'll see IntelAudioService and "Stopped Working" under summary. That is probably the one issue I have truly had with this laptop - The audio will randomly stop. It's nothing a restart can't rectify, but n...

This section covers hacking! Remember: I'm taking only a sliver of the information presented to give employers a better idea of what I know and am capable of learning, not copying someone's course word from word. You know why we don't use Telnet anymore? Because of this. This is in clear text.

This is David Bombal's course on Udemy . Screenshots will be scarcer because, hey, you didn't pay for this. I did. This covers the first 4 sections (Sans the OSI model): Introduction Setting Up Using Filters Setting Up: 

You don’t want to “upgrade” a server. Everything’s got history, you, me, and technology, despite companies’ best attempts to even physically scrub encoded data off of machines. And maybe it’s not compatible with the older hardware. So, here’s role migration — Role onto a new server, with all the configuration of the old one.

In the end, Windows 10 is still very reductive and looks like a child's toy. The only understandable aspect is people using legacy programs and 10 having to be on a HUGE variety of devices.
