#What is DHCP and How It Works?

[ghoulangerlee]

morally it is sometimes okay to lie on your job application/resume/etc to get a job if you know you can do the work to do said job (i lied on mine about how good i am at excel, fuck pivot tables all to hell, ive watched nth youtube videos on those when i need them) but it's never hindered me from doing my job.

BUT MAN someone lied real big on their resume and application and she had her interview on Friday and it was such a hot mess. my boss asked her so many questions that she had zero answers to. What's DHCP, what's DNS (these aren't necessarily things that she should know, but she confidently stated to him she did know them but then couldn't tell him what they were, I was mopping the floor in the back and I could hear her voice raise and she was panicking and trying to laugh off the fact that she didn't know it, it was wild).

When asked how to enroll a user in Entra, she couldn't explain that process either despite her experience listing that she had enrolled users in Entra before (even I know how to do that by virtue of reading my coworkers' notes on the process).

My boss asked her if she had experience with firewalls, she confidently said yes and when he asked her what types, she told him "oh the standard ones".

There aren't really "standard" firewalls? I mean. People have their preferences. I know more about Fortigates because that's what we have at work and deploy to customers. (I don't deploy them, but I deal with their security service renewals so I know the ins and outs of that nonsense). But she couldn't even name one. Cisco. Checkpoint. WatchGuard. SonicWall.

When asked if she could stage a user on a desktop, she didn't really have a clear process for it, despite her resume saying she had 10+ years of workstation staging experience. This is a muddy question tho, we aren't looking for the process as much as, do you know how to set up a user in AD, do you know how to set up their email, do you know the basics? Do you know how to join a computer to the domain and things of that nature.

She didn't know the difference between Windows Home and Windows Pro.

Which, all of this was a huge red flag to my boss when he started questioning her. And like kudos to her for thinking she could somehow pull the wool over our eyes on this but??? We aren't like most IT companies, each tech has a very hands on job where you have to know that a computer needs to be upgraded to Windows Pro in order to be joined to the domain, you have to know how to add a user to Entra when an onboarding comes in, you should know to have DHCP set up on a server so it doesn't make things weird, and you can't just lie your way through it. You have to have the practical knowledge or you're going to be found out really really fast. (in this case 10 mins into the interview.)

Like 😩 if you don't know something then say you don't know it and move on. Don't lie.

I started using Firefox again recently because of Manifest v3. Now YouTube's "Three Videos and You're Blocked" Warning is appearing again, even when I have ublock and MalwareBytes enabled. Is watching YouTube via Waterfox a good alternative?

First off make sure it's uBlock Origin, original uBlock isn't effective and iirc not actively maintained as well as uBO. I have no problems currently with uBO+Waterfox nor uBO+Firefox.

I think the three-strike thing is still in A/B and you might have better luck resetting your router to try and get a different IP and roll the dice on getting out of the three-strike group. This is very router/ISP specific however, some ISPs may not give you a new IP on reset.

Use a web IP tool and write down your IP then try the reset method and see if you get a new IP associated with your router. Here, I'm talking about the one from your ISP. It might require figuring out the DHCP timeout and staying disconnected long enough for the IP to expire. If it doesn't work with a five minute reset, try to find a time you can leave the router turned off for several hours and see if it gets a new IP. If that doesn't work either, then your ISP likely ties your IP to your account and you won't get a different IP.

If you don't mind the hassle of logging back in to sites, it wouldn't hurt to clear your cookies out too. Idk if this matters but I go with no history and auto-delete cookies. Other than that there isn't much else you can do if you have the latest uBO, and you can't reset your IP. The other option is a VPN which you can hop around until you hit an IP that isn't in that specific A/B pool but this also has it's drawbacks.

For what it's worth, I just ignored those messages when I got them for a few days and then they kind of just stopped showing up. I don't know how many or if anyone really got blocked from the service. I also happen to be someone who logs in to use YT as well, and I don't know if that does anything or not. Best of luck, I hope it's just an outdated extension since that's the easiest to deal with.

fuck it i'm gonna buy a new router and i'm gonna wait to get a modem another time. it should still work if i force the xfinity box to just work as the modem and then i can set the pi to be dhcp server? i think.

and then i can set the whole network to route the dns requests through the pi and block all the ads

idk how well it'll work on youtube ads which is what i really want it for because it seems like a good bit of them are actually hosted the same place as the video so it's not a separate dns address and won't get blocked but even if it reduces the frequency while i watch youtube on my tv i'll be happy with it

If you are on mobile and hate that there are fewer good ad-blocking options, but you're willing to try something slightly more complicated, you can set up a **Pi-Hole** as your own **Domain Name Server** (DNS). DNS is how your computer translates a URL like analytics.carmax.com into 104.121.122.102 or whatever (we call this "resolving" the URL). Most DNS providers will resolve any URL that comes their way, but a Pi-Hole is a DNS that you control, and it's built to deliberately fail to resolve URLs for advertisers.

The steps are pretty simple:

Get a Raspberry Pi with enough horsepower to run the software (this kit is $110, but cheaper ones can still do the job)

Install the OS and software. I thought this would be a nightmare but the prompts are well written and mostly explain the consequences of what they're asking you to choose.

Configure your phone, laptop, etc. to use the Pi-Hole as their DNS when they're on your home Wi-Fi.

Optionally, go into your Wi-Fi router and have it make _everyone's_ DNS the Pi-Hole. (Super optionally: use the Pi for DHCP. I prefer not to do this.)

Once it's working, whenever your device tries to load an ad online, the web page will ask your local network "hey, where can I get a shitty ad ?" and your Pi Hole will reply "nah, don't worry about any of that, internet don't have no shitty ads no more."

I don't like ads

for anyone who doesn't know how to use tumblr without ads, the easiest way is to open firefox or whatever browser you use, download an adblocker extension, and log into tumblr through the browser. it will work on mobile as well. there are some other great extensions too like tumblr savior and xkit rewritten, but a basic ad blocker should work just fine :>

CCNA Certification: Why It Matters for Networking Professionals

In the ever-evolving field of IT, staying updated with the right certifications can determine how fast and how far a professional can grow. One such globally recognized credential is the CCNA (Cisco Certified Network Associate) certification. If you're wondering what is CCNA, it's a foundational certification offered by Cisco that validates a networking professional’s skills in installing, configuring, and troubleshooting networks.

ok time for wifi troubleshooting dump (for Windows but the concepts are true for any device)

First, how this happens. Imagine you had a router that wasn't plugged into anything but power, and a laptop with an ethernet port. If you plugged the laptop into the router, you would get a similar message of "connected without internet" but it would show an ethernet icon with instead of wifi icon.

What that error means is that you did, in fact, connect to the wifi. That's layers 1 and 2 of the internet. Trouble is, there's more layers, and you need all the layers to use the internet.

Layer 3 of the internet is the Routing layer. Yes, this is where the name "router" actually comes from, but I digress. This is the layer of the internet that deals with "IP addresses". Where your computer or your phone or TV or whatever normally gets an IP address from is something called "DHCP". Dynamic Host Configuration Protocol.

You don't need to memorize that. Just know that after you connect to a network with wifi or ethernet cable, one of the first things device will do by default is send a broadcast on the network asking "Hey! Is anyone here a DHCP server?" This works because certain sorts of broadcasts don't need your computer to know how to use the network more than just being connected to it.

The addresses used when asking this are actually 0.0.0.0 and 255.255.255.255. If those sound like special addresses, that's cuz they are. "no address" and "everyone who can hear this". Anyways...

Your home router by default is running a dhcp server on it, so it SHOULD hear this broadcast and it SHOULD respond and your computer SHOULD negotiate whats called a "DHCP lease". This basically is just a bit of information saying "ok so here's your address and subnet size, here's your default gateway, here's some DNS servers, it's good for [LENGTH OF TIME HERE]."

The first thing to check is, did DHCP work? Right-click the network icon, whether ethernet or wifi, and chose "Open Network and Internet Settings".

Then go to the network properties of either the ethernet or the wifi, whichever one you're connected to.

Yours won't say "connected" cuz yall internet is broken but the buttons are still there.

The big thing you're looking for is the "IPv4 address". IPv6 is different don't worry about it right now and usually if IPv4 is broken then IPv6 is broken anyways, if your internet provider even serves you IPv6... ANYWAYS.

If you have an address like 192.168.something.something or 10.something.something.something you probably got a DHCP lease so that's not the issue.

If you have an address like 169.254.something.something then that means that either the DHCP server didn't respond, or it did respond but your wifi signal is so bad that your computer didn't hear the response.

Restart your router, look into changing the wifi channel settings on the router to a less occupied channel, try using 5ghz wifi if possible though not everyone's computer or router supports that, sometimes restart your computer cuz sometimes Windows' networking software does stupid thing.

Also, unless you KNOW you're supposed to be using Static addressing, make sure you're set to Automatic. Someone may have turned off Automatic addressing cuz they're a prankster. Or they don't know what they're doing. Or both.

Well, if you got to this point because you aren't having a DHCP issue, then things get a little tougher cuz the "internet is out and you should call your ISP to find out if it's a wider outage that they're already working on fixing or if it's just you" possibilities start to show up now.

Time for Command Prompt. I promise it's not nearly as scary as you might think.

Alright, time for our first command. Type in "ipconfig" without the quotes, and hit enter. It'll spew out a bunch of text at you, but it's not as complicated as it looks.

I crossed the things in thick red out cuz I don't trust tumblr to not pull some shit, and the one thing in thin orange because it's fine if people see that but it's in the middle of some stuff we want.

Yall have used Discord at some point, right? You see that Default Gateway? We're gonna ping it. "ping 192.168.1.1" or put whatever your gateway is instead.

I'm on ethernet with properly functioning equipment, so my ping delay is <1ms (less than 1 millisecond). Wifi is gonna be higher, anywhere from 10 to 200 milliseconds, depending on your wifi quality.

Also, if your wifi connection is really bad, you may see "Request Timed Out".

If you're having trouble pinging the gateway, you may want to do a ping test. Adding a -w 50 (wait 50 milliseconds) will make the computer not wait long for failed pings, and -n 40 will make it try 40 times instead of just 4 times, cuz we need more data than just 4 tries.

This'll take a while to run (about 40 seconds to be exact). If you get tired of it running or just everything is timing out constantly then you can press Control C (like copying something in a text editor) to interrupt the program.

The big things to pay attention to are the "round trip times" and the % loss.

If your % loss to the gateway is 100% then either your computer is configured wrong and you should check that you're using the right addressing, or your wifi is extremely bad, or extremely rarely your router doesn't respond to pings on its local network. This is almost never the case. Your router probably doesn't respond to pings from the internet for security reasons, but pings from the inside are good for troubleshooting.

If your % loss to the gateway is over 10%, and/or your times are consistently very high (over 100ms or so) then your wifi conditions are extremely bad. Either you don't have enough signal strength, or there's heavy interference and basically your computer and router are effectively trying to have a conversation while at a loud metal concert. Neither of them can hear eachother very well.

There might be something wrong with your internet service provider still; but if you were wondering why using your wifi is suffering even when the internet isn't out, that's a hint.

If your % loss to the gateway is over 1% but under 10% then that's Not Great and you should still look into wifi channelization but it wouldn't stop you from being able to use the internet entirely.

Under 1% is okay, that means it's not a wifi issue.

The next thing to try is to ping a well-known usually-up service, such as Cloudflare Public DNS (1.1.1.1) or Google Public DNS (8.8.8.8) or Quad9 (9.9.9.9)

My internet is working fine, so I have 0 loss and while there is some variance (one got 34ms instead of 11) everything looks peachy.

If your pings to one of these public services all fail, then either your router needs to be configured because either 1. it wasn't set up in the first place (you would not believe how many people I take calls from that have this issue) or 2. it factory reset itself for some reason (some people think that rebooting the router means use the reset button. IT DOES NOT MEAN THAT.) and you need to pay attention cuz if it happens again that may mean ur router is screwed.

Or, there's an actual service outage, and you should call your ISP to find out if it's just you, or if it's a general outage and they're already working on it and all you can do is hurry up and wait.

And... that's it. There are other weirder issues that you can have, sure. As long as this post is, explaining some of those issues would take even longer. And I would LOVE to explain some of them. But this post is already more than long enough, and it covers the vast majority of cases.

Thank you for reading and good luck!

when the wifi says "connected without internet" how about i fucking kill you

home networking log #0

i realized recently after much research and flashing rpis to prep for setting up pihole, that i actually dont know how my current home network is set up. this could end up causing me problems if the isp has locked down dns and other settings i need configured for that to work

i cant construct a useful homelab environment if i dont understand the basic topology im working with, so the aim of this project is configure a basic network by way of:

configuring a switch to run ethernet to multiple devices, like an rpi or nas. do i need power over ethernet?

learn more about how my gateway dashboard works, what i can change and why i would do so

learn about vlans beyond the creation of a guest network

create a diagram of my network topology: where are my ethernet jacks? do they all meet at the network panel in my closet? what kind of ethernet do i need? should i use patch cables?

optional: separate out my modem and router. what exactly is a router? is it simply a combination of dhcp and dns servers thats also a wireless ap? maybe a small switch built in?

next up: investigating my router and network panel
