All right, we’re back. So, uh, my goodness, this video is enormous. We have just finished up setting

up the, uh, the forwarding and the wireless access point and DNS mask and all that stuff.

Now we need to find out if the access point actually works. So the pie is sitting on my

desk. It’s got the dongle plugged in and, um, I want to log into a machine that can connect,

to do i have a nested virtual machine here that i made just for this video i’m calling it inner ubuntu

so you should release your inner ubuntu

i guess hopefully this even boots i only used it one time um let me get rid of like the

the toolbar is it going to work my cpu is now burning out of control

okay this is going to be super slow i’m just telling you right now

this computer’s already pretty crappy and i have a hypervisor that i’m recording on

and then inside that sorry i have a virtual machine that i’m recording on and then inside

that virtual machine there’s another virtual machine that we’re launching it’s like

it’s the virtual machine inception so let me see if i can log in here

Let me see if I can log in here.

Okay.

Seems to have booted.

Let me look at the details real fast.

Oh my God.

I don’t even know where I am anymore.

There’s like three toolbars that I’m looking at.

Three start menus.

So network manager, now I’m back from another cut.

For some reason I didn’t type the SSID incorrectly.

Well, la de fricking da.

So I’m just going to, I guess I typed it in wrong.

Copy pasting it seems to work this time.

Anyway, successfully activated.

So if we do, so remember this inner VM, it doesn’t even have a network card.

It only has the Wi-Fi dongle.

I can do ping 8.8.8.8 to see if we’re online.

We are actually online.

The access point works.

It’s routing.

it’s routing um this should be able to ping my main router 1.1 yep and then 1.101 nice so basically

at this point let me try like a domain name here google.com yeah okay google.com works let’s try

ipv4 works ipv6 unreachable well we’re not on ipv6 i guess i forgot yeah we didn’t add ipv6 yet so

for the regular you know the old school IPV works so at this point the clients

connected to the PI access point can access the rest of the network and they

can access the internet the next thing that we should probably think about

doing is increasing the font size of the dang terminal but besides that I want to

have the rest of the network be able to access clients behind the access point

because you know for me I want to be able to set up servers that are a little

to set up servers that are a little bit further away and you know boost their signal with an

access point what’s going on here i hate this terminal you know what i don’t care i’m going

to do it i’m going to install terminator because i know how to set up the fun size on that one

anyway so the next thing pseudo app update update is what we have to do first

the next thing i’m going to do is set up a route so that we can connect from land clients to clients

So if you look here at the recording that we’re doing, at the main VM that we were in this entire time, we can’t actually ping stuff that’s on the.5.1 subnet.

In fact, we don’t actually even know what the address is.

So if you notice, I can ping 192.168.1.123, and that works because the pi.123 is on the same subnet as the rest of the network.

subnet as the rest of the network. I can also ping 192.168.1.147

because that is also part of the same subnet as the rest of the network.

I can’t ping 192.168.5.1 because

I guess I can, but for sure we’re not going to be able to ping the client that’s inside of the

so I can just get out of this freaking tournament.

And so you can,

because I know this is kind of hard to read, right?

I don’t like that I’m showing you

like a super small front screen.

If you can’t read,

maybe I should just tell you what we did real fast.

I mean, you saw the commands to connect before

on the outer VM,

but I’ll just remind you,

you sudo network manager CLI we wouldn’t do connection add we would actually say device

Wi-Fi connect and then we would name the SSID you know the SSID’s name and then we would say

the password and we would do like you know some kind of password here and then we don’t have to

specify the interface name on the nested VM because there was only one network device at all

So now I can get out of this awful terminal emulator and just go into Terminator.

Pin to the dash.

Unpin to the dash.

And then I can send a bigger font size.

References.

Profiles.

I’ll just make like a really big font size for the rest of this video.

Oh.

where’s a boon 2 mono

reminder later open to sans mono regular that’s an okay terminal font not the best but okay so

now you can see it’s like a little bit better so what are we doing uh we just proved that this

inner vm can see the internet and it can see the lan but this uh machine can’t really see

can’t really see items on the inside. Let me show you what I’m worried about right now.

If we say IP address and show one of our wireless LANs, oh it’s got this huge name, it’s not WLAN0

like on Raspberry. So this is the wireless adapter that we plugged into the inner VM.

It’s got this IP address that has been given to it automatically from DNS mask.

so that uh or sorry a dhcp server so it’s a something.74 that means now we know what address

it is using so we’ll know what address should probably fail let me just double check this real

fast 5.74 not 1.74 yeah so it’s on the other subnet so we’ll ping 5.74 why is it working

i i pushed a bunch of routes the other day

day. I guess they’re just still in there. Okay. This was the whole surprise. Let me just get rid

of this. Sorry. Uh, sudo IP route delete and then just delete that whole entire thing.

I put a route into my actual router. I thought it wasn’t working though. Maybe it’s actually

Anyway, we’ll talk about that.

So now if we just kind of look at IP routes, now these are like normal routes.

This 123 that’s like for the VM stuff, so it’s fine.

Anyway, if you go back to the ping area, if I hit enter a bunch of times to diagnose the

network, notice how the pings are still showing up for the normal subnet 1.something, but

they’re now no longer showing up for 5.something.

So that’s what was going on before.

I already had the good routes in there.

So now the question is, I mean, if you don’t want to be able to have your normal land machines reach clients behind the access point, then you can just be done with this whole video.

But if you want to be able to reach them, maybe they’re going to be servers.

Maybe you just want to like SSH into them or like access something, you know, access them in some way.

Then you need to be able to reach your machines, right?

So how can we do that?

Well, the first thing that you can do is add a static route.

route so you know what is a route this is not a video about routes it’s basically just a way to

say how do you get to that subnet you get there by making your next hop to this particular ip address

so if i go sudo uh ip route add this is linux you can do the same thing uh basically in like your

router and windows and stuff like that leave a comment if you would like me to make a video for

you know any other topic explaining further if i get enough votes i’ll probably just do it

votes i’ll probably just do it so we’re saying we’re going to add a route that will go to this

new subnet and the way that we get to this new subnet is via this ip address which is on the

current subnet notice how this is dot 1.47 147 was the uh the wireless adapter of the pi

the primary wireless adapter the the internal radio so it’s basically saying if you want to get

to subnet 5.something then you got to first bounce onto the wireless radio of the pi and we know how

of the pi and we know how to get to that because that’s on our normal subnet you don’t have to do a

proto static metric and all that stuff that’ll be filled in later but uh you can specify a device

to hop onto so for this particular machine it’s just basically got ethernet so we can specify

you need to hop out on the ethernet adapter versus like some other adapters that you might have but

I just say to get to that other subnet we’ll just hop on to the pie so now that I added that

notice how right away the other pings start coming back so that’s all we really need to do is just

add that route how do you make that permanent though because this is not going to last after

we reboot this virtual machine so let me delete the route real fast whoa what happened no such

let me just double check here

maybe I can like oh because that extra stuff at the end is not in the route

that I just added so I’m deleting the route notice how these pings suddenly

stop how can I make this persistent well you can go into the settings of your

connection and just specify some routes in there so notice how I’m in a program

called XFCE I’m basically going into the network settings and I’m saying edit

connections if you’re on a different version of Linux or a different network

manager or like Windows or whatever you can just go into the network settings

the wireless settings the Ethernet settings and edit the settings and if

you poke around long enough and look at all the different tabs and things that

are offered you’ll eventually find a place that lets you specify routes notice

on automatic but it’s got a button called routes so if i click on the routes button oh that’s why

it was in there i left it in the actual dialogue so um yeah this is all you need to do you click

the add button and it says what address do you want to uh be able to get to and uh you just type

an address yeah i could have typed dot five dot zero but i chose to type dot five dot one just to

remind myself uh and then the net mask uh usually we’ve been seeing a slash 24 block but that’s the

block but that’s the same thing as this 255.255.255.0 it’s kind of the same meaning they’re just

in different formats i think the format on top is called cidr and i can’t even remember what the one

on the bottom is called i think it’s like just a regular subnet mask or something um so you say

in order to get to that machine the gateway um with this uh mask meaning let’s just get to any

any machine on that particular subnet,

then this is your next hop.

The gateway is the PI’s Wi-Fi adapter

that we assigned earlier.

So when I hit okay,

I should be able to just like disconnect and reconnect

and it should just work.

So again, it’s already working right now,

but the reason it’s always working

is because I had that in there.

So let me just disconnect one more time.

Notice how all the PI’s, sorry, all the pings stop.

stop. What’s going on here? Terminal is frozen. All right. That’s weird. Why isn’t it letting

me get enter? I don’t like it. So then if we just go back to the wired connection, suddenly

everything works all over again. That terminal is just frozen, dude. Okay. Let me just check

my notes real fast. Is there anything else that I needed to talk to you about? Yeah.

Well, I guess one thing I should mention, this is not a video about

administering your actual router, like your primary router. It’s kind of a pain in the butt

to add a static route to every machine that you want to be able to access a client, you know,

on your access point on your new Pi repeater. For me, that’s only like three or four machines. So I

just entered it, it’s fine. But if you want every single machine on your LAN to

on your LAN to always know how to get to clients

behind the access point,

you have to have your router push a static route.

There’s a way to do that actually with your DHCP server.

Some routers have like a nifty interface

that is just called static routes

and you can just start entering them in there.

Some of the routers, you know,

they want you to edit the DHCP server and type like a number

and then like do all these weird conversions

to get like a hexadecimal string.

decimal string. I’m not going to go over that in this video. Just know that you can manually add

static routes here, or perhaps in the future, add static routes at the router level, which will help

all clients. But that’s how you connect. That’s how you do it. Just to prove the point here.

What was the IP address of the client? Right. So like this, yeah, that inner VM, I think it’s on

74 at the very end so I’m on regular LAN right now even though this is a VM it’s actually hooked

up to my regular LAN at least like for the moment I should be able to access it via SSH it’ll say

connection refused if I wasn’t able to access that subnet um it would just

time out or say unreachable or something but it should say connection refused if the SSH server

it might actually try to connect.

Let’s see what happens.

Connection refused.

That means I did make it to the inner VM,

but the SSH server is not on.

So let me just prove this to you a little bit more.

Pseudo apt install, open SSH server.

So when this finishes,

we should be able to connect over SSH

basically finished our wireless repeater only got like three minutes left until the camera cuts me

off again hope you uh learn some stuff let me just try to connect real fast yep see how it’s asking

me now do you recognize this machine so it actually worked so after all of these hours of

watching me just ramble on nonsensically i hope you’ve learned a little bit of stuff and i’ve

now enjoy your new Raspberry Pi Wi Fi repeater. I know I’m

enjoying mine already. I’ll see you in the next video. Don’t

forget to tell your friends and subscribe and do all that fun

stuff. Have a great day you deserve a long hard rest for

rest for watching all this video footage. Okay, I know for me,

I’m so tired and sweaty right now. People at the gym when I go

later are probably going to be like what’s going on with this

dude unless I take a shower before the gym, which doesn’t even

even make sense, but I might do it. So anyway, I’ll see you in the next video. Thank you so much for

watching. 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

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 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

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 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 uh 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 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

cool music as I fade into the darkness which is coming for us all.

Thank you.

Okay, we’ve started a new scene here.

I just cut the video.

I edited it a little bit so that we could, so that I could have more recording time before

the camera dies.

The camera is going to take a poop.

Anyway, so next we need to set up IP forwarding because what’s going to really happen is when

you send a request, let me see if I can find that image real fast.

Where the heck is that?

No, I’m not.

It’s right here.

So this is the after image.

image. So if you think about it, what’s going to happen is when your clients send a signal,

you know, to the Pi, the Pi is not the internet, the Pi is just connected to your router.

The Pi then needs to forward the data, the packets, whatever to its other interface. So

this is like, you know, wireless LAN one, and this is like wireless LAN zero, if you recall.

ability to forward packets between interfaces so that we can get the packets to wireless LAN

zero and then they’ll eventually end up being sent to the router. So that’s the basic idea of

what we’re doing now. And then also IP masquerading. So I’m going to close this and then go back to

Let’s see. So there’s a configuration file called system control in the etc directory.

So we can do cat system control dot configuration.

A lot of its stuff is a braid out or I guess like not configured by default.

So if we edit it, what’s going on there?

Dude, what is happening?

You see that?

Oh, I did pseudo nano, pseudo nano.

That was dumb.

So a lot of these options are just they’re commented out.

You know, they’re not like enabled.

commented out you know they’re not like enabled so this is a good idea for security purposes but

we definitely need to forward so

i’m going to uncomment net.ipv4.ip forward equals one to enable ipv ip forwarding on ipv4 and then

i’m going to uncomment the next one for ipv6 forwarding even though no word even though we’re

It’ll be a pain in the butt if you start trying to set up IPv6 on your own later and you forget to come back to this file.

So that’s what I’m going to do.

So we can immediately apply the changes with this command if we want to.

I’m just going to put it on the screen real fast.

But we don’t need to because I’m going to do a reboot after we set this up.

So the next thing we need is we actually need to install a firewall so that we can keep persistent firewall rules

that will help us IP masquerade. At least this is the way I know how to do it. So by default,

this operating system doesn’t actually have IP tables installed. The pie is totally open and

unprotected. Kind of weird, but okay. So I’m going to go sudo apt install IP tables so I can get a

firewall. And then I’m going to install install IP tables persistence. Actually, let’s do persistent

later so that we don’t have to do any other commands. When you install persistent, it’ll

it’ll grab whatever’s already in there and just make it persistent so you don’t

even have to remember extra commands if you’re wondering why we’re installing a

firewall at this point it’s not necessarily to protect the PI although

we can use that to protect the PI pretty soon or like later but it’s really so

that we can have masquerading work which is in this case it’s very closely

related to forwarding data from the two network adapters so I’m gonna go so we

installed iptables I’m going to say iptables list all the rules are empty everything is open the

firewall is really letting everything through so then I’m going to do sudo iptables network

address translation post routing if the source is coming from oh yeah if the source is coming

from your access point and it’s trying to go out to the to the ethernet adapter that’s wrong that’s

that’s wrong that’s not going to work for our purposes eventually

we’ll say the judgment is that it’s okay to masquerade

um we should replace this with wireless LAN zero also so that they both work

basic idea is if a client of the pi access point is sending information into the pi like it’s it’s

making a web request then we’re saying it’s okay to masquerade as that ip address as we send the

as that IP address as we send the data along to either the ethernet port or the wireless LAN port.

So I put both of those in there because I want it to work for both.

You may only need to put wireless LAN 0 or whatever your adapter is

for the one that’s making the primary connection to the original router.

So now let’s make the rules permanent with IP tables save.

Oh wait, no, we don’t even necessarily need to use save if we just install persistent

after we did it.

Whoops.

App install persistent because I think it’ll ask us if we want to save the rules right

now.

Yeah, right.

Okay.

So I’m going to say, yeah, so I can save myself some commands.

Yeah, go ahead and save them.

If you installed persistence right away, you could either uninstall them and then reinstall

them, I guess.

the command is basically this to take whatever rules are currently inside of iptables and then

just send them into that saved rules file and then you would do the same thing for the v6 if

you wanted ipv6 double check what has been saved with this command so we’ll say sudo cat and then

that’s the file where the rules are saved so it’s telling me yeah they are saved so if i reboot the

rules should still be there now. And then we have enough time to set up the access point.

We are very, very, very close. Yeah, it’s probably actually going to work now.

Set up the access point. And

yeah, I’ll show you how to do a debug thing after this. I’m not going to do it

so you can see, but I’ll show you how to do it. Anyway, so let’s set up the access point. Remember,

access point. Remember, we’re only connected with one of the radios right now. So pseudo network

manager, command line interface connection show, and we’re only connected as a client. So now we

need to do this pseudo network manager command line interface connection add not device Wi Fi

connect, but connection add, the type is going to be Wi Fi. And then we’re going to specify the

interface name as wireless LAN one, that’s the dongle that we installed earlier. And then we’re

so that’s mode AP and then I’m just gonna set the connection name to become

access points you can obviously set this to whatever you want it doesn’t really

matter and then we have to set the SSID probably this should be different than

your main router because we’re not doing like WDS you know roaming access points

or anything like that this is gonna be a totally separate access point with a

totally separate network we’re just gonna eventually make it work so that we

seamlessly so that it’ll feel like one network but it’s technically another

subnet at least so choose something for your SSID that your neighbors won’t call

the police about I’m gonna do well la de fricking and then we’ll set a password

so I’m gonna just make up a random password right now in another window and

This thing is not working.

Hello?

Okay, I’m just going to copy paste a random password.

So I’ll set the, let’s see, what is it?

80211 wireless security.

Oh, you know what?

It’s probably easier if I just do this from inside network manager.

So I added the connection.

The SSID is well loudy freaking dot.

Then I can just kind of show the connections become access point is not up yet.

So I’m going to edit it.

Connection edit become access points.

So now it’s, I don’t know, for me, it’s a little bit easier to edit all these things.

So I’m going to do set 802.11.

is kind of like you know the wireless family of standards dot band oh for the band depending on

your dongle uh you might want 2.4 gigahertz or 5 gigahertz also depending on your country

for me i’m gonna try to get this on 5 gigahertz so that is band a uh i think the other band is either

actually you know what network manager will tell me yeah bg i was gonna say just g by itself yeah

gigahertz at least for this then I’m going to do set the wireless security property of the key

management and I’m going to set it to basically a pass pass key or like a pass phrase some of

these settings are probably going to be out of date by the time you watch this video so you might

want to go look up the latest or ask me a million times to provide an updated video I guess although

kind of kind of over it to be honest i hope this works for everybody because regardless i’m eating

an entire pizza by myself when this is finished let’s see group let’s see proto group pairwise

um so we’re just type we’re just typing stuff now now psk so that’s the uh the password so then

i’m gonna paste the random password that i just came up with and then uh hit enter to get that

And then we’re going to set up the IP address.

Remember, this is another adapter.

We still need to set its IP address.

So IPv4.addresses,

I’ve got to do set, sorry.

Addresses 192.168.5.1, which is what we decided on.

And then block 24, yes to manual.

And then I’m going to set its gateway to nothing.

Oh, the gateway has to be empty.

I made this mistake earlier.

mistake earlier if you actually set the gateway to something like you probably want to do 192.168.1.1

if you do that then the access point will tell all of its clients that the gateway is 1.1

but the problem is they can’t actually access 1.1 so they’ll just be offline so you need to make

sure probably that the gateway is empty so we’ll do print ipv4 notice how the gateway is empty

DNS is empty DNS searches empty they all should just be empty because we want

the information to come from elsewhere at least on that on that so uh you know we want DNS mask to

tell them everything if those have values you can basically say remove ipv4 dot addresses and then

it should work so let’s see what else do I have to add addresses gateway DNS DNS search and then

11 wireless security just to double check it.

Make sure that you’ve entered all the right values

and then print the IPv4 block again just to double check it

and then hit save.

If you have an error here, you might want to type fix, verify,

or maybe just go look at all the settings again.

But I saved it.

It seems to have worked.

So I can now quit.

And then, oh, actually, maybe I should tell it to start automatically.

Let me just double check.

Print the connection properties.

properties. Does it say auto connect? Yes. Okay. So now the access point should automatically come

up whenever, uh, whenever the pie boots, if we’re lucky, we’re incredibly close right now.

So I’m going to do, I’m going to open up another window and I just want you to kind of see what’s,

what’s going on here. Um, or how I was debugging my connection. Cause in the beginning, when I was

first learning how to do this, I was like, where are the packets going? Is it even trying?

trying so for me I made several windows like this if your terminal doesn’t split

windows too bad for you mine is called terminator you can find it pretty easily

it’s sudo apt install terminator but what I what you want to do is SSH into

the Ethernet of the PI three times so I’m gonna do that and then oh god is that

figured something out. So you want to do it three times and then you want to label each window.

So this window is going to be wireless LAN zero. Depending on your terminal, you might have to do

labeling differently. Wireless LAN one and then I’m going to do Ethernet zero on this one.

So they all, we have three terminals, one for each interface, network interface. And I’m basically

to watch packets on every single interface.

So inside of the Pi, I’m going to first say sudo apt install tcp dump.

That’s a special program that lets you watch packets as they’re traveling all around your

network cards and stuff like that.

So sudo apt install tcp dump.

Then the command is sudo tcp dump and then dash i to specify an interface.

And then we’ll specify ethernet zero here.

and then uh here we’ll specify wireless LAN zero we’ll just match the windows that’s why

i labeled the windows and then here we’ll do wireless LAN one uh and then so what you’ll

want to do is hit enter on each of these windows and you’ll see like a huge stream of data you want

to uh filter the data by something that’s useful for you otherwise it’ll be like way too much data

I filtered it by ICMP echo and then what I was doing is I was basically just pinging servers like

I was pinging inside of the Pi I was having it ping itself and then I was having it ping like

my router then I was trying to have it ping clients and then I was having the clients ping the Pi

and ping the router and then finally start pinging the internet you’re just doing pings all over the

place in order to try to narrow down what might be wrong with your situation if you follow this

tutorial probably it’ll be fine but like for me you know I like to debug and things were going

wrong when I was first learning this so this was super super helpful I just want you to know

here’s a problem though every time you reboot the pi let me do that right now you do sudo reboot

every time you reboot the pi you lose connection uh connections to all the other windows so then

you have to like log back into the pi and then type out the command all over again so instead a nice

Instead, a nice shortcut could be something like this.

SSH into the pie.

SSH pie at 192.168.1.123.

And then in quotes or single quotes,

I’m gonna do single quotes on the outside

and then double quotes on the inside

because you kind of have to use different quotes.

Now what’s gonna happen is when I go into the pie,

it’s gonna log into the pie

and immediately start doing the TCP dump for me.

that means when when I get booted I just have to I just have to hit the up arrow and I can

immediately go back into the pi and I don’t have to type out the commands again let me show you

real fast with a slightly different way so I’m going to go ssh pi at 192.168.1.123 and then do

a single quote and instead of doing tcp dump I’m just going to type echo by itself so notice how

I didn’t echo anything. Hello. It logs in, it prints hello, and then it logs out. So now

I’m kicked out of the Pi. Let’s pretend that we lost internet or network. I just hit the up arrow

and hit enter. So it’s like so fast. You don’t have to type all those letters again.

So I’m not going to debug here. I’ll do that in another window if I really need to, but

I just wanted you to know. And it’s fun. It’s fun to know when things are really starting to work.

probably rebooted. Now let’s try some, well, we know that the PI’s network works for itself. So

now the next step is how can we prove that this access point actually works? Oh my gosh.

I think I’m going to cut the video so that I can show you that it works

by logging into a virtual machine that’s inside of this virtual machine that I’m recording on.

It’s probably going to be super slow. We’ll see what happens. Okay. So I’m going to cut the scene

Okay, so I’m gonna cut the scene right now. When I come back, we’ll be logging into a virtual machine.

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 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.

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,

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.

suggestion for uh uh 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 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

into the darkness which is coming for us all.

Thank you.

Yeah, there we go.

Okay, so we’re back.

I went away.

I forgot exactly what I told you before I cut the video, but I went away.

I recorded a different video where I installed the drivers for this Wi-Fi dongle.

I compiled them from source.

I found them on GitHub.

I wanted you to go to that video and use it to learn how to compile the drivers for your

own Wi-Fi dongle.

If you want to have the same dongle that I have, that video I should have a link to where

a link to where you can buy the same dongle that I have.

But if you have a different dongle, that’s okay.

The instructions in the other video should probably help you.

So at this point now, you’ve gone away to compile the drivers for your Wi-Fi

dongle and you’re back, you’re ready to continue making your Pi access point.

So what we should do is I’m logged into the Pi right now.

And let’s use Network Manager to see what’s up.

Let’s use network manager to see what’s up.

Network manager connections show.

We only have ethernet up right now.

We want to connect as a client to your existing router.

So remember we have two radios.

One is going to be the internal radio of the Pi or a dongle if you wanted to buy two dongles.

And then the other one is going to be the dongle that we’ve been talking about.

So I mean, I’m saying you can buy two dongles and stick them in the Pi if you want a little

bit more range.

For me, I just use the internal of the Pi and then the dongle as the external.

the external so the dongle is going to connect nowhere it’s just going to be an access point so

that other clients can connect to it so I’m going to connect as a client specifically using wireless

LAN zero because that’s the built-in ethernet sorry wireless adapter of the pie we can do this

in network manager we don’t even need a desktop we’ll say pseudo network manager device Wi-Fi

connect and then we just have to specify the name of your original or how about your primary

original or how about your primary access point you know whatever it is whatever your wi-fi

credentials are you got to put that there i’m not going to show you i’m going to type this into

another window so that you don’t have to see the name of my access point let me go sudo network

like that the name of the access point and then after that you have to put a couple more things

in so you’re going to do the interface name you should name which radio you want to do the

connecting as a client so I’m going to put WLAN zero because that’s what we just said if name

WLAN zero in the other window and then you want to provide the password for your wi-fi access

point so I’m just going to put password here your password here and then I’m going to type that for

And then I’m going to type that for myself up in the other window.

Oh, shit.

There we go.

Okay, I think that’s probably all we need right now.

I’m just going to hit enter on my other window.

You should hit enter now.

it’s saying that it does not see the network we forgot to turn the radio on the the wi-fi adapter

is off right now so that’s that’s a default thing with the raspberry pi so we’ll go into a tool

called raspy config raspy config raspy config um you could use a program called rf kill to activate

the radio but the raspberry config is more fun so what you want to do is uh after you say you know

sudo-rasby-config, you go into localization options, and you select the wireless LAN country.

So that’s, you know, because different countries have different regulations, they’ll restrict like

the frequency bands you can use or whatever. I’m not sure about all the countries, but I’m going

to find United States in the use. There’s only a few of us, only a few use. And now the Wi-Fi

idea, I go to advanced options and select expand file system. Because if you remember, I’m going

to do a reboot real fast. Yeah, if you recall, we, what’s going on, man, I want to ping.

We wrote a very small image to the card. It was only like two gigabytes or something, right? So

that means the file system is only two gigabytes, but the card is way bigger than that. And I want,

to be able to take advantage of all the space on the card so that’s why you expand the file system

and raspberry pi has like a nice little tool that helps you do that so it’s pinging again i should

be able to get in there okay uh going back to my other window real fast i’m just going to check that

the uh the connection actually worked so wireless lens zero oh it didn’t even work last time for

sure so we’re gonna we’re gonna repeat that command because the wi-fi wasn’t on before right so

the wi-fi wasn’t on before right so so if you recall uh we did sudo network manager device wi-fi

connect and then the name of your access point and then if name wireless land zero and then the

password i’m going to type that into my other window here and if we’re lucky it’ll connect

yeah okay it seems to uh have worked and then sudo and see what you should show okay

rename the connection real fast and then I’ll show it to you in the main terminal windows

so you do network manager connection edit main one and set the connection ID to how

about just like connect as client save quit show okay so now I think I can show you this

so it’ll pseudo network manager command line interface connections show and you can see

connected as a client to the rest of my network. At this point I could pull out the ethernet

adapter if I wanted to, but I still don’t like doing that because it’s pretty easy to lose your

connection and screw everything up and the ethernet is there to save you. But for now I have connected

as a client on wireless LAN zero. Make sure you have the right one selected. And if you did it

wrong you can do pseudo network manager connection delete and then just name the connection. But I

So let me just edit the IP address real fast.

Edit, connect as clients.

You’re probably gonna wanna do this

because remember we talked before

about the idea of you having IP addresses

that you had to come up with to follow this video.

So I’m going to, oh gosh, what’s happening?

There we go.

Let me go to this one.

Right, so I’m trying to set up wireless LAN 0 so it’s going to be 147 for me.

Maybe not the same thing for you.

So I’m going to go, let’s see, I just edited it.

Okay, so I’m going to set ipv4.addresses as that with a 24 block.

And yes, I want to set to manual.

I want to set the gateway.

Basically this is the same thing that we did with the ethernet already.

Then I’m going to set the DNS.

DNS, the only difference here between, you know, this connection and the ethernet connection

is I’m just setting a different IP address, but I’m giving it the same gateway and the

same DNS servers and everything.

So DNS search, home, I’m going to save it and then I’m going to quit it.

At this point you could reboot the Pi.

Maybe I should do that so I can read my notes a little bit more.

Let’s reboot the Pi and let’s see if we can connect on the wireless interface.

interface so I think it was 147 I just set up let me do a ping at 147 so I’ll

know if the Wi-Fi comes on I may have forgotten to tell it to auto connect

like I did last time but I feel like the Wi-Fi does that already we’ll see what

happens I’ll just give it like 10 more seconds yay it worked okay so now we’re

through the wi-fi notice how it says i don’t recognize this remote because it’s a different

ip address but we’re on the pi so now you’ve got two ways to get into your pi i’m actually going

to revert because i like staying on ethernet but uh just so you know this is how the pi will get

its internet after you eventually put this repeater somewhere where you can’t get ethernet you know

like in your garage or on top of a china hutch or whatever so um the next thing that we need to do

The next thing that we need to do is, um,

we need to install a program called DNS mask. We need a DHCP server because what’s,

what’s going to happen basically is when we connect it as a client to the primary router,

its DHCP server gave us an IP address on the normal subnet. So that’s fine. We don’t really

need that for the primary connection. But when we become an access point with the extra antenna,

connects to our pi as a client is going to need ip addresses and it’s not going to be able to get

the ip address the clients are not going to be able to get the ip address their ip addresses

from the router anymore because they’re not even connected to the router they’re connected to the

pi and there’s an isolation because there’s two different networks so that means we need to put

a dhcp server on the pi so the pi can just decide what ip addresses everybody has on its network so

I think what I’m going to do since the video is already about 15 minutes long into this particular segment

and I think the whole video is already like over an hour for sure

I’m going to pause the video and I’m going to go away and make another video

where I just talk about how to install DNS mask on your Raspberry Pi

so you should go to that other video and then come back

when you have a DNS mask all set up

and then maybe I’ll just copy paste the config

config that i’m actually using for this particular project just to make it more clear this is the

sample configuration file for dns mask it’s not too bad that that’s kind of it it’s kind of all

you have to do so uh i think i’m just going to install dns mask right now for you what i did a

moment ago is i said sudo apt install dns mask so it’s already installed for me and then to give it

called etc dns mask and any file you create in this dot d directory and this is kind of typical

for programs that recognize a dot d drop directory you can just stick configuration files in there

and they’ll be read automatically so this is the configuration i’m going to use for my dhcp server

on my pi you should probably use something similar but not exactly the same or not necessarily it

I’m using my search domain of home so you don’t have to do that because you don’t even you probably don’t even have the home domain unless you want one and then I’m gonna I’m gonna specify what IP addresses should get assigned to clients that connect to the access point.

the adapter this doesn’t work otherwise I guess it’s fine by default nobody’s

gonna be looking at this PI I don’t know maybe I should specify the adapter I’ll

make a note or I’ll come back in a second but anyway so we want to specify

an IP address range if you recall our IP address range that we chose for the

clients of the access point is going to be dot five dot something right so this

the subnet should match what we’ve chosen.

So all of the IPs that we give away should start with 192.168.5 and then something.

So notice out here I’m just saying 192.168.5.10.

So I’m saying that the first IP address that I will give away is a something.10.

And the last one that I’ll give away is a something.150.

I think most people don’t go up that high, but I just feel like it.

I want to go from 10 to 150.

and that gives me a little room to statically assign lower addresses if I really feel like it later or

High addresses if I feel like it later

This subnet right here. That’s the same thing as a slash 24 block

It just means only the last number should be able to change and then the least time 24 hours

That means if the if the PI

DHCP server gives an IP address to a client then that IP address should last for about 24 hours before the PI has to decide

decide um you know on another ip address or if it’s going to give it a longer lease or something

on the same one it’ll just it’ll just redetermine what’s going to happen uh then we’ll send a dhcp

option uh basically we’re going to tell the clients hey here’s the ip address of your gateway

so that’s called option three for dhcp options so we say three comma and then the dhcp server is

going to be dot five dot one at the end because that’s the number we’ve designated for wireless

for wireless LAN one, the gateway, you know, the wireless dongle that we’re setting up.

Then we’re going to send DNS servers.

You need DNS servers so that your clients can actually resolve names to addresses,

you know, like yahoo.com or google.com instead of their numbers.

So that’s going to be option six.

And then you basically just put every DNS server you know about,

or you want the clients to know about, separated by commas.

Just to point out also, we’re not covering IPv6 in this video

covering IPv6 in this video because we’re trying to keep it short but you probably want to continue

eventually and set up IPv6 on your own at some point but this will totally work without it

so my DNS servers are 1.101 but again you probably don’t have those as DNS servers

yours are probably just going to be the IP address of your router or maybe you can put in some public

DNS servers like 8.8.8.8 whatever you do write it all down there and save it

and before we try to run dns mask let’s watch messages and see what’s going on

actually you know what let me just type it and i won’t show you because there’s probably

sensitive stuff in there you use a command to watch service logs called journal control so

you’ll say pseudo journal control dash dash unit and then you just name the unit that you’re

interested in watching if you type if you press enter right now you’ll see all of the logs and

you’ll be able to scroll up and down, hit Q to exit.

But if you just wanna follow the logs in a live view

to see maybe problems as they’re occurring,

then you’ll do a dash F for follow.

I’m gonna do that in my other window right now,

just so that I can maybe catch myself

if something goes wrong.

So I’m gonna like copy paste this up here on a terminal.

Blup, blup, blup, blup, blup.

Okay.

So it says,

I think it actually just like reset itself once I change the config file.

That’s kind of cool.

So, but then the next steps you want to do just to be sure that this service is actually going to run for you.

You’ll say sudo system control status DNS mask.

And then it says it’s enabled on my system.

So then I’m going to do sudo system control enable dash dash now.

And that’ll just ensure that it’s enabled.

so it’ll start whenever the system boots and then it’ll start it right now also and every time you

change the configuration you probably want to do something like restart I actually I’m not sure you

need to do this because it looks like it was picking up the config while I was typing it and

saving it so pseudo apt sorry pseudo system control enable now and then restart and then

the DNS server should be running let’s see how much time do we have seven before I have to cut

So now we’re at the point where we have to set up IP forwarding because what’s going to happen is…

Actually, you know what? Let me do a scene cut because this is going to take more than seven minutes.

We’re almost there. We’re actually almost finished.

Well, not quite. We’re getting closer.

Okay, I’m going to do a scene cut.

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

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

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

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.
