Hey there, let’s talk about using your Raspberry Pi as a Wi-Fi repeater, Wi-Fi extender, just

to help make the Wi-Fi signals a lot better in your home.

So for starters, I just want to make a disclaimer. It’s actually a lot cheaper and easier to just go

to the store and buy a Wi-Fi repeater. But if you’re like me, and you like to do everything

and fun why bother driving down to the store when you can stay inside all day long and do it yourself

so uh uh i’m using an old raspberry pi that i found in a drawer this is like a raspberry pi

4 it’s not really that old um after i do this video i’m going to do the same thing with the

raspberry pi 3 which i think should probably also work um and i was about to throw this pi 4 away

and then i realized i could turn it into a repeater so it actually did save me money in the

let me just talk about your your prerequisites real fast what you

actually need you obviously need a Pi you know in like the power and all that

stuff you need an SD card so that you can write an operating system to the Pi

hopefully if you’re watching this video you already know that but the the major

thing that you actually need that you probably don’t have yet is you need an

extra radio you need an extra Wi-Fi adapter for your Pi because the Pi by

radio antenna, you know, Wi-Fi adapter, Wi-Fi card. But you need two because one is going to

connect to your existing router, your existing Wi-Fi access point. And then the second one is

going to become its own access point so other clients can connect to it. Let me kind of show

you a plan of what I’m talking about here. I made a crappy diagram. I hope you like it. I’m not very

good at these things. But if you kind of look on the screen right now, you can see that this is

This is the situation before you add some sort of a Wi-Fi repeater or the Pi repeater.

So this was what was happening to me.

Spoiler, I already did this.

So I kind of remember how to get this working pretty quick.

So I have like a wireless router here and it’s also the regular router

and it’s connected to the modem and stuff.

And the devices that are close to the router get lots of fast, good connection.

But the devices that are kind of far away, like way over here in the back,

here in the back maybe like a server a printer another laptop a phone whatever they lose

connection they they have slow speeds they’re spotty they’re frustrating right i think probably

most of you deal with this um so the the wireless repeater or the pi that we’re going to do right

now is going to solve the problem at least hopefully or mostly i don’t know so i’m going

to show you a diagram of what it’ll be like when we’re finished we’re actually going to create a

a second network. Notice how on the first slide, oh, I already lost it. Let me do it.

Notice how on the first slide, we just had one network here. For my personal network,

this is just 192.168.1.something. And then that slash 24 means the last number is able to change.

We usually call this a subnet. Honestly, this is not smart to have a standard subnet in your

home network, but I’m kind of lazy. Maybe I should change that soon. You should know in advance,

in advance this is part of your preparation and research you should know what is the ip address

of your router your existing router you should know the existing subnet that you’re running on

if you don’t this is going to be extremely hard for you to do most people though if you just get

a router and install it it’s either going to be a one right here or a zero right here very rarely

will i see people with like a 10 0.0 dot something and if they do somebody else in their family or

or business set it up for them already so we start off with only one subnet one network all

only one subnet one network all the devices can talk to each other without

all the LAN devices can talk to each other without routing when we’re done

we’ll end up having two networks so just notice real fast again this is the

initial network you know this is the thing that we had before 192.168.1.

something and then these close devices they’re still going to connect to the

router notice how you know this green line right here it’s not or sorry this

well no it doesn’t I’m totally lying oh no no I am not lying I lied about lying

basically the router is connected still to the original devices that were fast

on the router so there’s no reason to move devices that didn’t have a problem

but notice here instead of having one long blue line going all the way to the

devices in the back this this this blue like connection squiggly you know image

the internal radio of the Raspberry Pi.

And then the Raspberry Pi will have a second antenna

that’s going to be, you know, one of these things.

I’ll show you how to install this and all that stuff in another video.

I’ll talk about it.

That second radio is going to connect and be an access point

to all the other devices that are far away.

And if we’re lucky, what will happen is the signal won’t get too bad

by the time it hits the Pi.

It’ll probably be like, you know, hopefully okay.

okay, kind of fast, not too spotty, at least, you know, not as spotty and bad as it was going all

the way to the devices in the back. And then because this is digital, the Pi is going to

actually repeat the signal out on the second antenna from, from scratch. Like it’s going to

give a fresh signal. It’s going to be the same data, but it’ll be, you know, renewed, repowered.

So if you think about it, that’s kind of like having the wireless router a lot closer to the

lucky then the devices in the back will have a much easier time connecting so and and getting

speed and being reliable and all that stuff the only thing that we really need to deal with though

is in order to do this we have to create a second subnet so at the very end of this video we’ll

talk about routing and we’ll just we’ll just do a couple of commands to make sure that um

the devices in the regular part of your lan network can actually reach and connect to and

end. We’ll add a static route to make sure that these two subnets can talk because by default,

they wouldn’t be able to talk to each other. If you don’t really need them to talk, like let’s say,

I don’t know, maybe these devices in the back, maybe they’re just like your phone or

a computer that you only surf on or something like that. Then you don’t really need a route

if you’re not going to connect to one of those devices in the back as a server or something.

So, but you know, that’s what I like to do. So we’re going to do that also.

the first step, let’s see. I think the first step, oh, before we get the pie started,

we need to talk about your plan. So what is your plan? We’re going to, what happened there?

I lost, there we go. Okay. We’re going to plan what IP addresses the pie will have when we’re

totally done. You have to do this in advance, right? So we already talked about, you have to

might not be the same as mine and then we have to identify or not identify we have to choose what

the repeater subnet is going to be you don’t have more than one subnet if you don’t even know what

I’m talking about you could probably just choose any number you want for me I chose 192.168.5.0

keep in mind you probably want to have the first two numbers the same unless you’re in some sort

of a special setup you know there are numbers that you can use that are not that but this is

change that third number from a one to a five indicating there’s like a now now a dot five

something subnet uh remember that this slash 24 means that only the last number can change

for communication to work without routing so that means i don’t really want to interfere with my

existing subnet if i did you would probably mysteriously continually lose connection

while you’re trying to set this up and then later when it’s working so just

take it from me it’s more trouble than it’s worth so just come up with a new subnet

just come up with a new subnet if you’re thinking about doing bridge networking you can’t really do

that with a wireless radio that is connected in client mode I already tried that it didn’t work

so I mean for me I just had to make another subnet so write down whatever you decide as your

as your other subnet walk around and make sure that it doesn’t exist look in your router this

is the IP for my router at least right now and you should determine what your router IP is and then

And then you have to come up with three IP addresses for the new Raspberry Pi setup.

So the first IP address is going to be, what are we going to assign to the Ethernet port?

I said originally, this is just going to be, you know, a Wi-Fi repeater.

So we’re not really going to use Ethernet, except at the beginning, when we’re setting everything up,

it’s going to be much more convenient to be able to connect to the Pi.

Me, when I was practicing this yesterday, I kept screwing up the wireless settings.

And if I had not set up the Ethernet port in advance, I would have been locked out of the Pi.

I would have been locked out of the Pi. I would have had to like restart it and then hope for the best or maybe rewrite the whole card.

So, you know, once you get the Ethernet port working and you know, you can connect to it,

it makes things a little bit easier if you should screw up the wireless.

So then come up with an IP address for the built-in radio, the one that’s going to connect as a client to your existing network.

For me, I chose 147 and then obviously for the Ethernet 123.

Then you have to come up with an IP address for the second radio on your Pi.

you know, the antenna that’s going to become an access point, it should be on the new subnet.

So whatever you choose up here, you know, 5.0 slash 24, that means 5.something is valid.

I just chose 5.1 because it’s kind of a common thing that the gateway that is sort of like

handling traffic for other machines, which is what the antenna is going to do, is it ends in a 1.

So I’m just going to choose, you know, 5.1 because that’s kind of a standard gateway thing.

address is ready, I’m going to start installing the Pi. So the first thing that you want to do

to get ready to install the Pi, 12 minutes, that’s not too bad. I tend to talk a lot.

I got to chill, you know, I got to chill.

Is you probably want to go to the Raspberry Pi website. So I’m going to go raspberrypi.com.

What is this new stuff? I got to set up Firefox. Raspberry Pi, the foundation has got like an

and a com I think org is like more for community stuff so go to raspberrypi.com

click on software and let’s see so you could use the imager if you want to I’m

not going to show you how in this video I like to do everything manually what

we’re gonna do is download an image of the Raspberry Pi operating system and

then burn that to the SD card for the Raspberry Pi so again you know if you

if you don’t want to do it this way you can do it whatever way you know how you

the OS basically. If you’re interested leave a comment I am thinking about

making future videos where I explain how to do this from Windows but I’m in

Linux right now so I’m just gonna use Linux to do it. I’m on the Raspberry Pi

4 which supports the 64-bit operating system you should use that if your Pi

supports it. On my Pi 3 I’m only 70% sure that it supports the 64-bit

operating system I haven’t like fully explored it yet although it did run I

run. I don’t know if anything was broken, but I’m just going to click on the 64-bit operating

system. So you click that. Then you have, you know, choices like not flavors, but like levels

of stuff that comes pre-installed. So the 64-bit, double check that. Raspberry Pi OS, double check

that. Yeah. With a desktop, we don’t need a desktop for our repeater. Desktop with recommended

software, we don’t need that. We need the light version. That’s the leanest, meanest version.

that is the easiest and fastest to download install so click that download

button and what will happen is you’ll end up with an XZ let me copy that link

real fast you’ll end up with an XZ extension when you download it notice

how it says you know arm 64 light image XZ that just means the image is zipped

up so that’s that it’s faster to download if you had something that was

had something that was like that ended in a gzip extension then on the command line you would say

g unzip and then you would do you know the file name dot gzip or whatever it was since we’re using

uh xz i think it’s uh un xz as far as i recall let me open up a terminal real fast and i’m going to

go into my downloads and then another disclaimer i’m not really going to show you the basics of

about that in other videos um definitely uh command line basics i think maybe soon i’m going

to post um an ssh tutorial so if you’re like on windows and you want to be able to connect or do

command line stuff just basically see my other videos by the time you find this one uh you’ll

probably there’ll probably be a lot others that are up so i’m going to go into downloads here

and go into my iso folder i just like to keep things organized so

Yeah, that’s what I originally did.

So that’s the command to unzip an XZ zipped image file.

So now I just have regular dot image.

I don’t need to unzip it is what I’m saying.

So I would have done, if you don’t have XZ,

you can do apt search XZ on your computer.

It’s in here somewhere.

Yeah, I think it’s a XZ utils that’ll allow you to unzip.

So anyway, the next thing that I really need to do now

that I have the image is I need to burn it to an SD card.

it to an SD card and then I need to modify it for first boot which I think I will do in in another

video that I’ll link here or or mention here so again what am I doing I have like an SD card

it’s like a really you know small micro SD card for the Raspberry Pi and then I have a little

SD card reader and writer so I’m just gonna this is the first time I’ve used this one I have a

really cheap one behind me that sucks and I’m hoping this will be faster so I’m just gonna

stick it in and then so now the card is on USB so then I’m just gonna go plug

this in and oh hang on before you plug it in I almost forgot you don’t have to

do this but it’s kind of a good idea it makes it more convenient I’m gonna use a

program called parted to see what like disks and partitions and drives and

things I have available in the system so sudo parted if you don’t have that

it’s sudo apt install parted. I’m gonna say print devices and notice how it just

shows only one disk. This is a virtual disk because I’m actually in a VM right

now. So now that I know what disks are currently in the machine it’ll be easier

to see what disk just got added. So I’m gonna like push this in here. I saw a

spark! No that was a light. I’m gonna wait a second and then I’m just gonna very

machine to give that usb device to the machine that you’re looking at right now so you don’t

have to worry about doing this um genesis logic reader and writer the cheapest thing i could

possibly find i don’t know it seems okay though it was a it was a choice on the shopping website

that i went to okay so i mean this this proves that it worked i get annoying pop-ups uh because

basically i have like another operating system already on that card so if you get these pop-ups

you had something on the card before you probably want to unmount the card before you continue so

we know now that the card is uh showing up as dev sdb got to remember that and uh before i continue

i’m gonna unmount so you want to go mount this is linux again by the way and i’m gonna oops well

mount and pattern match it by sdb and those are the two mounts that i have so i’m gonna just

rid of that because if you try to modify a card that is currently mounted or a

partition or a drive or something that’s currently mounted you’ll probably end up

corrupting a bunch of data so you don’t want to do that mount pattern matching

against SDV so now it’s unmounted I don’t know if this is 100% safe at this

point but this is what I do so hopefully it’s okay just print the devices again

to make sure it didn’t disappear if it did disappear you probably have to like

unplug it and replug it or maybe reboot the computer because you use the wrong

because you use the wrong command or you click the eject button or something.

So now I’m going to write that image directly to the cart.

So I’m going to say sudo dd.

So this is the program that I use for writing images to disks and cards

and copying files and stuff like that.

It’s really cool and fast and versatile,

but be very careful because you could actually destroy your entire computer with this command.

So what am I talking about?

talking about so you have to specify the in file and that’s pretty easy uh if you get it wrong it

doesn’t really matter so i’m specifying the in file as that image that i just downloaded

then i’m going to specify the out file and this is where it gets super dangerous

you have to double and triple check that you’re typing the correct device and you’re typing the

device correctly so i’m literally going to look at it like five times i go out file dev sdb

devsdb has the right size that’s a 64 gigabyte sd card there’s nothing else except for my okay

you got to be paranoid because i i’ve done this one time in my life i used the wrong out file

and i basically watched my computer destroy itself in front of my face

and a little tear went down my cheek slowly anyway so then the other thing that i usually

like to put on here is conv fsync i don’t know if this is required for sd cards but it’s usually a

It’ll basically force syncing of the file.

Because like, for example, if you have a USB thumb drive

and you use DD to write data to the file,

the thumb drive sometimes lies to you

and tells you that data is written

even though it hasn’t been written

because the thumb drive is trying to appear

faster than it really is.

So if you just kind of notice that the command is finished

and you pull out the thumb drive,

you might have corrupted data

because it didn’t actually finish writing.

So I use conv fsync to try to avoid that.

And then I’m going to do status equals progress.

progress. So I can just kind of see what’s going on. Okay, so let’s see, double check FSDB and then

it’s all plugged in. Everything’s good. Okay, wish me luck. Then again, this is why I’m in a virtual

machine. If this gets destroyed, I don’t really care as much. Okay, it’s going incredibly slowly.

Just as slow as my old slow card reader. That sucks. Maybe the problem is my hypervisor then,

from this host machine to my virtual machine.

Okay, anyway, so I’m going to cut the video for a second here.

And hopefully you’ve gotten this far with me

and you’re ready to go to the next step.

Just maybe pause the video while yours is riding to the Pi.

And I’ll turn off my video now.

I’ll come back as soon as it’s finished.

And then we’ll continue.

We’ll do first boot on the Raspberry Pi.

Be right back.

Hey, everybody.

Hey everybody! Thanks for watching this video again from the bottom of my heart. I really

appreciate it. I do hope you did learn something and have some fun. If you could do me a please,

a small little favor, could you please subscribe and follow this channel or these videos

or whatever it is you do on the current social media website that you’re looking at right now.

It would really mean the world to me and it’ll help make more videos and grow this community.

So we’ll be able to do more videos, longer videos, better videos, or just I’ll be able to keep making

keep making videos in general so please do do me a kindness and uh and subscribe you know sometimes

i’m sleeping in the middle of the night and i just wake up because i know somebody subscribed or

followed it just wakes me up and i get filled with joy that’s exactly what happens every single time

so you could do it as a nice favor to me or you could you control me if you want to just wake me

up in the middle of the night just subscribe and then i’ll i’ll just wake up i promise that’s what

will happen also uh if you look at the middle of the screen right now you should see a qr code which

you should see a QR code, which you can scan in order to go to the website,

which I think is also named somewhere at the bottom of this video.

And it’ll take you to my main website where you can just kind of like see

all the videos I published and the services and tutorials and things that I offer

and all that good stuff.

And if you have a suggestion for clarifications or errata or just future videos that you want to see,

please leave a comment.

Or if you just want to say, hey, what’s up?

What’s going on?

You know, just send me a comment.

going on you know just send me a comment whatever i also wake up for those in the middle of the

night i get i wake up in a cold sweat and i’m like it would really it really mean the world to me i

would really appreciate it so again thank you so much for watching this video and um enjoy the cool

Thank you.

Hey there! Let’s talk about how to install your Raspberry Pi from scratch and get to first boot

and first login without actually having to plug in a monitor at all. This is a pure headless

setup because for me personally, I hate walking over to like a TV or a monitor or something

and plugging the Pi in or getting my portable monitor out. It’s just a pain in the butt.

card, get it all installed, and then connect to it and configure it right away. Of course this video

assumes that you’re not going to use your Pi with a desktop or a monitor at all because if you are

you might as well just start doing that. But for me you know a lot of my Pi’s are just headless

they’re servers or they’re fun experiments or whatever. So the first thing that we should do

obviously you need an SD card and you need an SD card reader so if you’re on this video you

card and an SD card reader. This is like a super old reader where you can stick a card in there.

I got a slightly newer one plugged into the computer right now and if you bought an SD card

or a micro SD card with the Pi you probably had a little adapter that came with it, a regular SD

card adapter. So you can stick the tiny little card into the adapter but if you’re lucky and

your card reader has a slot for micro SD you probably just need that. So the first thing that

is go over to raspberrypi.com their foundation has a common org i think org is more for the

community but go to raspberrypi.com and then click on software and download the raspberry

pi operating system so i’m going to do this the manual way i’m just going to write an image if

you want to do this with an imager or if you have like something else that you already know how to

do that’s totally fine go ahead and do it i really just want you to put the operating system onto

because I’ll be posting about how to do this with Windows and other stuff.

I guess you don’t need that if you’re going to use the imager,

but it’s more fun to do it manually.

All right, so notice how it says manually install an operating system.

I’m going to click on the download options.

Select the operating system so modern Pis can use the 64-bit OS.

That’s what I’m going to do.

If you have, I think, like a Pi 1 or 2,

you might be stuck using the legacy, like the 32-bit.

like the 32-bit what’s the difference between those two 32-bit oh don’t do legacy I think that’s

like really old I don’t know maybe it depends on how old your Pi is but just hover the mouse and

notice how one of them says 32-bit that’s what you would use if you’re if your board is not 32 but

as far as I understand I mean definitely the Pi 4 and the Pi 5 for me they worked with 64 bits

I think my Pi 3 worked with 64 bits although I’m not 100 sure everything was okay after install

was okay after install so just basically click on that then it’ll ask you all right what what

version of the 64-bit do you want to download uh if you’re going to be installing a desktop you

don’t really need this video so i’m just going to assume you don’t need a desktop you want this to

be totally headless so that means the desktop is too much it’s too much to download it’s kind of a

waste same thing for desktop with recommended software instead i’m going to click on the light

version because that’s the fastest to download and it’s all we need so i’m going to click on that and

So I’m gonna click on that and it’ll download.

And you could probably pause the video right now

because I already downloaded this.

So pause the video and then wait for your download to finish

and then come back with me.

This is where I chose to save my image file.

You probably actually don’t have a.image file.

You probably have an image that ends in the XZ extension.

If we look at the website again,

at least as of the time I made this video,

at the very bottom of that says.xz at the end.

That just means it’s a zipped image

so that it’s faster to download.

So in order to unzip that and make it a regular image,

you basically say unxz and then type the name of the file.

Actually, it would probably end in xz if you had it.

So you just kind of wait a little while for that to unzip

and then when you’re done,

it’ll show the image file like I have.

Okay, anyway, so now that we’ve downloaded the image file,

file the next thing we need to do is actually write to the SD card so I’m

going to take the SD card right now and stick it into the card reader.

Oh um this is going to be awkward.

Awkward!

My giant fingers aren’t working.

Oh I almost did it. I almost got it.

Oh man, welcome to my life.

Bro, I need a flashlight or something.

Oh my god, finally, finally, finally.

Okay, I am kind of in a dark room and it’s like upside down and my hands are big and

it’s like way over there.

It’s already plugged in.

already plugged in. I didn’t want to unplug the card reader because sometimes they don’t show up

again if you plug them back in and you have to like reset the USB root hub. I really didn’t want

to do that. So let’s see. The first thing that you probably should have done actually before

plugging in the SD card, so maybe unplug your SD card real fast just to check, is just take note

of what’s already plugged into your computer. I already know so it’s fine for me, but for you,

program called parted which is short for partition editor it’ll just show you what

disks and partitions and stuff you have in your system so i’m going to run it if you don’t have

it it’s probably for you sudo apt install parted i’m going to do print uh devices and

oh okay i’m on a host machine right now i got to send that usb into the guest so i guess it

all worked out notice how it’s telling me this is the only disk that’s present it’s like my

machine disk so then i’m going to tell my host machine to give that card reader to the guest

machine usb host device card reader finish hopefully the video didn’t skip or do anything

weird and then if i do print devices again now another thing showed up and uh i’m able to access

it i know for sure this is dev sd god damn it i know this is dev sdb because that’s what just

just showed up so remember that that’s very important you don’t want to get that wrong

and notice these annoying pop-ups that happen that’s because there was already a file system

on the card because you know i play around with these things and it’s not erased right now so

that’s okay you can just close these little pop-ups if you’re if you’re linux auto mounts

or anything like that but you have to unmount before you start writing to the card because if

you write to a card or a drive or anything that’s already mounted somewhere like then you’re probably

your data. So I’m going to do mount just to check what the mounts are and I’m going to search for

SDB since I know that’s the device that just showed up. So it’s telling me that it’s mounted

on those two folders which we recognize at this point because we just saw them pop up. So I’m

just going to unmount them real fast to make sure that I don’t screw anything up.

Okay all right and then one more time mount pattern matching with grep against SDB. Now

grip against sdb now they’re gone so it’s probably safe to write to the sd card now

so um the first thing that i’ll do is i’ll say sudo actually let me just list real fast the

image okay so we’re gonna write the image to the sd card using that card reader and

i should probably also point out that if you don’t understand what i’m doing on the command line

you could just follow along but i have other videos that are you know fairly decent tutorials

command line and connecting to machines over the remote and making ssh keys and stuff like that so

i’m going to go ahead and use a command called dd which writes directly to some drive or block

device it’s very very dangerous so be careful you could destroy your whole computer this way

i actually did this once a long time ago i didn’t check what the output specification was

and i watched my computer totally erase itself and a little tear went down on my cheek so we’ll

on my cheek. So we’ll specify the in file, if equals, and that’s pretty easy. I just have to

specify the image I just downloaded. Make sure you unzip yours before you do this. Then the out

file is going to be the block device that just showed up. devsdb. If you see other tutorials on

the internet with like, you know, sdb1 and 2, those numbers after the sdb or the block device,

those usually are just partitions. So you want to write the whole entire card, or sorry, the whole

the whole entire image to the whole entire card you don’t want to specify a partition

i’m also going to specify conv equals fsync for me it’s a little bit safer i don’t know if this

is needed on sd cards but for usb thumb drives they’ll sometimes lie to you and say that data

has been written even though it has not in order to appear faster than they really are so if you

do conv fsync it makes that safe again because you don’t want to you don’t want the command to

you unplug the device and then whoops you have corrupted data now because it didn’t finish

and then i’m going to do status equals progress just so i can see what’s happening

okay so uh at this point now we’re just waiting i’m going to watch the progress for myself very

carefully and then i’m going to uh i guess i’m going to pause the video and i’ll come back when

So you should just probably pause the video right now and then when your card is finished

writing then come back and resume with me.

We’ll do an initial IP address and we’ll connect to it.

We’ll set up the SD card and all that stuff without ever plugging in a monitor.

Totally headless.

It’s pretty sweet.

Okay, I’m going to pause.

Okay, I’m back.

So I had an issue that I want to share with you real fast.

the auto mounting service just came up and produced a folder and I get I got kind of scared and then

when I went to go into the files I started getting read write errors so I think I actually corrupted

my card I ended up disabling the service that auto mounts and then writing the card again from

scratch so just for you the command that you would probably need if you have the auto mounting

stop udisk2.service.

You don’t want to disable it

because you probably want it running

after you’re done doing all your installs,

but you want to do stop so that it stops right now

and then start the SD card writing

all over again from scratch.

So with that in mind, let’s see.

Hopefully this is going to show up now.

Pseudo parted.

And then I’ll do print devices again to see what’s up.

Okay, so it’s in there.

Now let’s see if we have read write errors

let’s see if we have read write errors or if it’s actually going to work this time.

So I turned off the auto mounting service, which means I have to mount it from scratch probably.

So let’s just double check to make sure it didn’t actually mount media mic. Okay. So nothing’s in

there. So that’s good. So now I am going to go into the temp folder and then the pie folder

and then the boot folder and the root are just going to be mounted. So I’m going to say sudo

is that what I just saw? I forgot. SDB, yeah. SDB1 goes to boot.

And then SDB2 goes to root. Now we have access, hopefully, to the file system. So I’m going to go

into the boot file system. So this is the boot partition that your Pi will have when it’s running

and stuff. So first thing we need to do is tell the Pi that we want its SSH server to be enabled

at boot. There’s not really that much that we have to do here. We’ll just

basically create an empty file with the touch command. So I’m going to say touch

SSH and now if you look there’s an SSH file it’s totally empty but that lets

the pi know that we want the SSH server to run whenever it boots. Then we have to

modify the command line so that we can set a fixed IP in advanced. So you know

sudo nano command line or vim or whatever you like to use. What you’re

like to use what you’re looking for here is root weight right after that you have to put the

specification for the ip address that you want so you probably should know what your ip address sub

what your ip subnet is before you start we’re not going to do ipv6 in this video but you know because

we just need ipv4 to get into the pi and then from that point you can configure it however you feel

or sometimes dot zero dot one whatever yours is you have to figure it out you have to go find out

what your router’s ip is your subnet is probably just the first three numbers because most routers

consumer routers default to a 24 block which just basically means the first 24 bits have to stay

fixed and the last eight bits can change for an ip address to be considered in the same subnet as

some other so for me i know mine is a dot one dot something so i’m going to assign 123 to my pi’s

ethernet adapter because that’s just what I want. You have to choose a number that’s available on

your network. If you don’t really know then it probably won’t matter too much because if you

fix a number that’s already in use the other computer will probably get kicked off the network

and then try to rejoin and then it’ll end up using a different number. Most DHCP servers that I’ve

seen on consumer routers will kind of stop at high numbers like they’ll go from 2 to 99 or something

So if you want to be like a little bit on the safer side, you could choose a higher number.

But it’s fine.

So right after root weight, IP equals, and then the IP address that you’ve chosen.

So that’s it for the boot partition.

Let’s go into the root partition now.

So the root partition is just like the root of the file system.

It’s got the actual root folder.

So that’s the home directory for the root account.

We could go in there and modify that if we wanted to.

every PI by default with these OS installs,

it comes with an account called PI

and it’s also an admin.

So it’s home folder is gonna be

the root of the file system slash home slash PI.

But for this particular mount, you know,

it starts at root.

So we have to go CD into home and then CD into PI.

So from your PI’s perspective,

it’s just gonna be this folder right here,

slash home slash PI.

I’ve mounted it so I see a different path.

If I list it, you can see some starter files for the PI.

for the pi. So I’m going to create a directory. I can do make directory and call it dot SSH,

a special folder where all your SSH configuration is. Again, if you don’t understand SSH or keys or

anything like that, see my other videos. I’ll talk about how to make SSH keys and connect from

Windows and connect from Linux and all that stuff. But it’s not too bad. You can just kind of follow

along with me. If you don’t have a key, by the way, on your host machine. So let’s let me go up

So let me go up here on the host machine.

You can do something like ssh-keygen type ed25519 and then just hit enter a bunch of times.

And you should be able to get your ssh key created.

You probably want to eventually learn how to put a password on it, you know, but that’s okay for now.

So I’m going to go into the ssh folder.

And I want to create a special file called authorized keys.

some SSH keys that will be allowed to connect into the Pi. So for my host machine, I’m going to

print out my public key, at least for this.

Oh, ID, right? I got to do IDED.hub. So this is just like a useless key. I mean,

the public keys are always okay to share on the internet. It’s fine. But like,

I feel better about this because it’s just my VM for videos. It doesn’t actually run most of the

Okay, something happened

Okay, so basically you just take this key the whole entire public key get the pub not the one that doesn’t have pub and just paste it into

Authorized keys file

So then we have to set permissions

The authorized key file we’re gonna go to mod. I think it’s supposed to be like six or seven oh

But basically the system probably doesn’t want any other user to have permission. So that’s why we do

we do something zero, zero, either six or seven. I think six might be it, but I’m just going to

stick with seven just to help this video go along a little bit faster. Make sure it’s owned by the

same user as the pi. In this case, the pi user is just sort of like the first user that was created.

So it’ll end up having the same user as you if on your host machine, you are also the first user.

user owner or maybe just do the root account instead maybe I’ll show you that real fast

so then we go up one level and the system probably also does not want the SSH key to be you know or

SSH folder to be browsable by other users it’s also kind of a bad idea so I’m just going to go

Chamod we’ll do like another 700 SSH it definitely has to be 700 instead of 600 if you don’t know

by the way then just see my other videos otherwise trust me but long story short

not a good idea to be able to let other users into your SSH folder so that’s why

I’m doing that at this point we’re probably done authenticating we can

probably jump into the pie but let me just show you real fast if we go into

the root folder permission denied okay sudo su root and then go into the root

tempPyRoot, that’s the root partition.

So really from the Pys perspective,

we’re trying to edit a file called slash root

because that’s the home folder for the root account

on the Pi.

It’s basically the same thing.

There’s like an SSH folder in there

and you can add an authorized keys file

if you wanna be able to log into the root account

on your Pi.

Otherwise it doesn’t really matter.

And I think we’re probably done.

Let me just double check my notes real fast here.

Oh no, I forgot to look at my notes.

I forgot to look at my notes first connection.

Did I forget anything?

I probably forgot a bunch of stuff.

Authorized keys.

All right, let’s see if it actually works.

So I’m going to now unmount.

Got to do that.

Don’t forget to unmount.

So I’m going to go sudo umount boot, sudo umount root.

If either of those say the device is busy, you probably are still in that directory

directory in like a different terminal tab or account or something.

You know, one of the mistakes I always make is I go sudo su root.

And then I forget that the regular user is actually still in that same folder,

even if I navigate to somewhere else in the root account.

So just make sure everything’s okay. Uh, and then you can,

if you want to double check, you can say mount, mount points, um,

boots and mount points roots.

And it’ll tell you that they’re not mount points. So at this point,

probably okay to remove the card from the card reader, remove the micro SD card, stick it into the Pi

and then I’m going to plug the Pi into ethernet because that’s the IP address that I just set up

so I’m plugging it into the ethernet real fast. You can’t see it’s off camera, I have a short cable

and then I’m going to plug it into its power. So now my Pi is totally on and I’m going to start

And I’m going to start trying to ping that IP address as fast as I can.

I should have started pinging before anything happened.

Because it’s more fun to see when the pings begin.

Would you agree?

No?

Okay.

Let’s see what’s happening.

I see some flashing on the Ethernet cable and the power lights.

I always get nervous that I’ve done something wrong when I’m being recorded.

Because, you know, in regular life, I do stuff wrong all the time.

And it’s fine.

And it’s fine. Nobody remembers.

I just have to, like, quickly catch myself and correct my mistakes.

Awkward.

This small amount of time has turned into a huge amount of time.

In my mind.

Wait, what am I doing? What am I doing?

Oh, that’s what happened! Oh, a huge mistake!

I forgot to put an extra number there.

For some reason, it filled in the zero.

For some reason it filled in the zero.

I was too rushed.

Okay, so the Pi probably came on a long time ago.

You’re welcome for the laugh.

So now that the Pi is online,

I can try to SSH into it and just hope

that my authentication works.

So I’m gonna do Pi at,

because I didn’t make a user account that matched Mike.

I just made a Pi user account.

So I’m gonna do that.

And host verification has failed.

So that just is because I’ve been using that same IP address

using that same IP address for different videos today. So I have to remove that from the memory

of my SSH client. So I’m going to go SSH keygen R. This is a good security feature. Basically,

it’s saying that your system remembers connecting to a totally different machine at that same IP.

So it thinks somebody is being hacked. So I’m just going to remove the record and then try to

connect again. Now it’s going to say, all right, do you want to connect? Do you trust this? I guess

And here we are, we’re inside of a Raspberry Pi now.

This is basically the end of the video because you can kind of do whatever you want now.

Notice how I never plugged in HDMI.

I didn’t have to look at a desktop.

I didn’t have to do anything except just connect to the Pi over the network.

For me, this is really convenient.

You just write the SD card, modify a couple of things, plug into Ethernet, and then boom,

you can configure it.

So you can go into, you know, Network Manager and like look at the connections and modify them,

and modify them, set the IP addresses however you want, set any other

configuration any way you want, harden the security. So the point of this video

is just how to get in without really plugging into a monitor. So thank you so

much for watching I hope you learned a little bit of stuff and had a little bit

of fun. I suppose I will see you in the next video.

Hey everybody, thanks for watching this video again from the bottom of my heart.

I really appreciate it.

I do hope you did learn something and have some fun.

If you could do me a please, a small little favor, could you please subscribe and follow

this channel or these videos or whatever it is you do on the current social media website

that you’re looking at right now.

It would really mean the world to me and it’ll help make more videos and grow this community.

So we’ll be able to do more videos, longer videos, better videos, or just I’ll be able

or just I’ll be able to keep making videos in general.

So please do me a kindness and subscribe.

You know, sometimes I’m sleeping in the middle of the night

and I just wake up because I know somebody subscribed or followed.

It just wakes me up and I get filled with joy.

That’s exactly what happens every single time.

So you could do it as a nice favor to me

or you could troll me if you want to just wake me up in the middle of the night.

Just subscribe and then I’ll just wake up.

I promise that’s what will happen.

Also, if you look at the middle of the screen right now,

the middle of the screen right now you should see a qr code which you can scan in order to go to the

website which i think is also named somewhere at the bottom of this video and it’ll take you to my

main website where you can just kind of like see all the videos i published and the services and

tutorials and things that i offer and all that good stuff and uh if you have a suggestion for uh

clarifications or errata or just future videos that you want to see please leave a comment or if you

hey what’s up what’s going on you know just send me a comment whatever i also wake up for those in

the middle of the night i get i wake up in a cold sweat and i’m like it would really it really mean

the world to me i would really appreciate it so again thank you so much for watching this video

and um enjoy the cool music as as i fade into the darkness which is coming for us all

Thank you.

Okay.

Hey there, let’s talk about how to boot your Raspberry Pi or part on yourself.
