This is Hacker Public Radio Episode 3,769 for Thursday the 12th of January 2023.
|
||||
Today's show is entitled Crouching Laptop Hidden Server Part Zero.
|
||||
It is part of the series' virtualization.
|
||||
It is hosted by some guy on the internet and is about 14 minutes long.
|
||||
It carries a clean flag.
|
||||
The summary is Virtualized Battlegrounds.
|
||||
Hello and welcome to another episode of Hacker Public Radio.
|
||||
I'm your host, some guy on the internet, and I'm here with...
|
||||
Art.
|
||||
72.
|
||||
Alright, so we're here with Art.
|
||||
72.
|
||||
He just posted something amazing in the chat room and I was like, oh man, we gotta talk
|
||||
about that.
|
||||
Now it's not fully put together yet, but we're going to discuss it anyway because it feels
|
||||
good to get in on the ground before the machine is fully assembled.
|
||||
So Art, you want to tell us a little bit about what you posted in the chat?
|
||||
It had no laptop and set up a Proxmox server on it and I just got to the install and made
|
||||
one change since I had installed it.
|
||||
So we're running Proxmox, ladies and gentlemen here at our Proxmox on a laptop.
|
||||
What kind of specs are we talking about here, Art?
|
||||
I believe in I3, but I'd have to go back in the notes in the computer and look up the
|
||||
specs.
|
||||
Roughly in I3, you got a good idea for the amount of RAM we're going to have on this bad
|
||||
boy, or are you playing an upgrading it in the near future, or...
|
||||
No, I think 8 gigs of RAM, I can't remember what I have.
|
||||
Oh, that's going to be a close one right there.
|
||||
8 gigs?
|
||||
What's the...
|
||||
What's the plan?
|
||||
What was the minimum number of VMs you're thinking you're going to be able to get on this
|
||||
thing?
|
||||
Three possibly.
|
||||
Let me look at the web UI, it probably tells me what the RAM is.
|
||||
So if we're looking at about 8 gigs of RAM, 3 VMs, that's going to be kind of close.
|
||||
From understanding this Proxmox system has devian as a base?
|
||||
That's right.
|
||||
I don't know.
|
||||
It's showing on the UI that I only have 4 gigs of RAM.
|
||||
That's weird.
|
||||
I thought I'd put more in there.
|
||||
That's going to be playing it very close.
|
||||
That will.
|
||||
I think I need to get more RAM.
|
||||
I've got to have some extra line around, right?
|
||||
Now I have to look at the specs closer and see what I can put in it.
|
||||
Well, for a laptop, I wouldn't go above.
|
||||
Well, if it's a guy 4 in it, now I just slap an 8 gig stick next to it and call it
|
||||
good.
|
||||
I could do that.
|
||||
So we might have to get back together later.
|
||||
Oh no.
|
||||
This is still going to work.
|
||||
We've got a roughly an i3, 4 gigs of RAM.
|
||||
That means you can still get 1 VM off the ground for now, right?
|
||||
Right.
|
||||
All right.
|
||||
Now, that 1 VM that we're talking about, what are you playing?
|
||||
I'll deal with it.
|
||||
I think I'll start with Arch, because it's pretty lightweight.
|
||||
Actually, that's the funny thing is that's where my username comes from, because I used
|
||||
Arch for six years or so.
|
||||
Oh, so we got a little background story here.
|
||||
User name plus the distro, you're going to be running on it, and I'm assuming this
|
||||
is going to be Arch headless.
|
||||
Yes, it is.
|
||||
Now, oh boy, Arch headless.
|
||||
What are you going to be running on a headless Arch system?
|
||||
That sounds pretty crazy.
|
||||
Like I said, it's the ground floor, so I don't quite know what I want to do yet.
|
||||
I just saw a video on how to do prox marks, and I thought it might be an interesting challenge
|
||||
to do.
|
||||
I'm thinking a little crazy.
|
||||
What do you say you just run it out there on the wild for a little while on the open
|
||||
net?
|
||||
You can maybe host the next cloud instance out there.
|
||||
On Arch?
|
||||
Maybe.
|
||||
Yeah.
|
||||
I mean, well, with four gigs, it'd be kind of tight with the lamp stack.
|
||||
So maybe not, maybe not a next cloud, that might be a bit tight.
|
||||
Yeah, it is.
|
||||
You kind of build it up as you go, and that's why I had liked it before, and then I don't
|
||||
remember what happened, but I tried to talk about Slackware, and so I was like, oh, I'll
|
||||
try that.
|
||||
I still like both.
|
||||
I never use Slackware, and I've only set up Arch once a long time ago in the VM, but
|
||||
I didn't actually use it as a system.
|
||||
I just wanted to say I set up Arch.
|
||||
Any chance we can convince you to self-host something out there in the wild on the raw,
|
||||
untamed internet.
|
||||
Yeah, sure.
|
||||
That's worth a try.
|
||||
Now this, this is going to be great.
|
||||
My laptop that I'm going to be running, it's an HP, one of those cheaper HP laptops
|
||||
that have the, what is it, the I3 in it?
|
||||
It's the model 14-CK0052CL.
|
||||
Mine is an Intel Core I3 2350 CPU with 2.3 GHz.
|
||||
I think we're running roughly the same type of system here.
|
||||
Right, that's about right.
|
||||
Now mine the last time I checked, I think I got either 8 or 16 gigs in there.
|
||||
Maybe it had 8 and I put 16 in it because I still got the laptop RAM from other older
|
||||
laptops or whatever.
|
||||
It's mine running a boom to 2004, and I'm thinking I'm going to put this puppy out there
|
||||
in the wild as well.
|
||||
I'm going to be taking a different approach using some of the documentation I got from
|
||||
Red Hat.
|
||||
Yeah, I tried Vert Manager to, it's a second-level hypervisor, unless the difference between
|
||||
Proxmox and VertManagers, VertManagers, our Proxmox is on the bare metal.
|
||||
All right, here we go.
|
||||
I just found it right here.
|
||||
All right, so it's going to be using a VertManager with QEMU and KVM, or you use VertInstall
|
||||
to create your disks, or not your disk, your VMs.
|
||||
So the rail documentation I found for building and setting up your VMs, just all from the
|
||||
command line, is excellent.
|
||||
They obviously want you to run it on rail or sent off stream or whatever, but the same
|
||||
packages work over on Ubuntu as well.
|
||||
So that's the root I'm going to go with it, and I'm doing it mainly just to get my command
|
||||
line food up there, because the other method was just to use VertManager, the GUI, build
|
||||
your VMs there, and then migrate them over to the system and then run them that way.
|
||||
That's what I was doing through the GUI.
|
||||
So far, yes.
|
||||
I didn't have to do anything after the install, just plug in my ethernet, and then after
|
||||
that log-n-d.com, and comment out those things where you can close the laptop lid.
|
||||
Oh, yeah.
|
||||
Got to definitely hit up that log-n-d.
|
||||
Yeah, that did work.
|
||||
I can put that in one else later.
|
||||
With my setup getting started, I'm going to have to install the packages QEMU-KVM,
|
||||
the package libvert, and the packagevert install.
|
||||
And from there, I'll be able to use a couple of simple commands to build a VM.
|
||||
This laptop isn't going to be running large VMs, obviously.
|
||||
So I guess it'll be like, you know, I'll just be testing it on small and medium.
|
||||
Now have you toured with any of the bridging in Proxmox to be able to get this thing out
|
||||
on the network that the VM?
|
||||
I know.
|
||||
I've just gone as far as the log-n-d.
|
||||
That is going to be interesting as well.
|
||||
I really want to know how this process is going to work with me just trying to do it all
|
||||
from the command, just trying to set up a bridge and get this thing.
|
||||
It's an IP on the network.
|
||||
I was just wondering the same thing because I can't even get a basic VM.
|
||||
I got VM tiny, missing some of the functionality of VM.
|
||||
Oh, in your VM?
|
||||
You already got launched?
|
||||
Yeah, they have a web interface, web UI.
|
||||
They have a place you can go to the shell.
|
||||
I was using that to change my log-n-d.
|
||||
That's one of the things I like about it.
|
||||
With that UI, you get that flexibility of like using a VPS where you can jump on the
|
||||
node or wherever and use the delish terminals that they have online.
|
||||
So with Proxmox, they're giving you that same sort of flexibility, but on the land using
|
||||
the web tool.
|
||||
All right.
|
||||
We just got back.
|
||||
We were looking at a few bits of documentation and anything interesting you found there,
|
||||
Archer?
|
||||
No.
|
||||
You found more documentation than I did.
|
||||
Yeah.
|
||||
I mean, we both stumbled across some really good bits and pieces, a couple of YouTube videos
|
||||
and lots of docs from Proxmox.
|
||||
It seems that they allow you to, let me go pull that up here.
|
||||
So from the Proxmox website, if you were to, from the main page, go over to the Downloads
|
||||
tab at the top, scroll all the way down.
|
||||
You'll then find the downloadable PDF documentation, which gives you a lot more information to work
|
||||
with.
|
||||
So even if you haven't downloaded and ran Proxmox yet, you can get that documentation
|
||||
at least get a good peak at what you'd be getting yourself into if you were to use Proxmox.
|
||||
And Archer ran across a lot of other wonderful docs out there from a, there's a site called
|
||||
Bob Cares that has some great information on breaking your VMs out, setting up their
|
||||
virtual bridge and some VLAN information.
|
||||
That's all going to be included down in the show notes.
|
||||
And also the YouTube link.
|
||||
That's where I actually got what got me interested in the beginning.
|
||||
Right, right.
|
||||
The YouTube link shows just how easy it is to get set up in Proxmox.
|
||||
And Archer, you pointed out something earlier about how lightweight it is.
|
||||
Could you tell us a little bit about that?
|
||||
I apparently only have four gigs of RAM and I thought I had more, but it's only one
|
||||
running using one gig around.
|
||||
So we're talking about a system with four cores and four gigs of RAM.
|
||||
You loaded up Proxmox on there as your operating system, which is a devian base with the
|
||||
Proxmox hypervisor.
|
||||
You're only running right now up and running with only one gig of RAM.
|
||||
That means in the future when you're ready to expand, you've got plenty of room to, you
|
||||
know, plenty of wiggle room to give your VMs more, uh, process, well, maybe not too much
|
||||
processing power because it's tonight three, but you don't have to starve them on the
|
||||
RAM side.
|
||||
No, and it has four gigs of swap to and I'm guessing that we'll change if I add more
|
||||
RAM.
|
||||
Yeah, I think for now, because you're limited on the RAM, they probably put in a swap
|
||||
and there's a good idea, you know, any services start filling up that RAM pretty quickly.
|
||||
You want some swap?
|
||||
And I think it creates that automatically.
|
||||
I actually made no changes except for that, like I said, log in D. Next step is to expand
|
||||
the storage from the video, yeah, I mean, delete the one of the volumes and then expand
|
||||
the remaining volume, but I didn't do that yet.
|
||||
We're going to take two approaches here, ladies and gentlemen.
|
||||
Archers going to be using the fantastic Proxmox with all this wonderful documentation right
|
||||
here.
|
||||
I mean, honestly, I'm kind of jealous just looking at it.
|
||||
It looks great.
|
||||
Looks easy.
|
||||
There's lots of nice videos to help guide you along.
|
||||
This is, this is wonderful.
|
||||
I'm going to attempt something similar.
|
||||
I'm going to be running a Ubuntu and doing mine through the command line, but I'm very jealous
|
||||
of this UI and I'm thinking for a UI of my own, maybe running a cockpit.
|
||||
I think a Ubuntu has a version of cockpit that can be downloaded, installed and, you know,
|
||||
quickly configured to run on the network.
|
||||
And from cockpit, maybe I won't be able to set up VMs from there, but I can still migrate
|
||||
VMs over to the system if I need to from my desktop.
|
||||
I'm going to try to do it all through the command line.
|
||||
They'll just get the system set up that way and just use scripts whenever I want to
|
||||
log a new VM.
|
||||
And of course, I'm going to put it out on a great wide open.
|
||||
So in a future episode, when me and Archer get back together, I want us to have some information,
|
||||
you know, our highs and lows of this entire setup and some information on what to expect
|
||||
when running on your home network.
|
||||
Alright, so Archer and I just ran through a little bit more documentation, finally some
|
||||
great DNS services out there.
|
||||
And Archer, any of them, you want to recommend?
|
||||
Duck DNS, if you don't mind that Google is one of the login options and GitHub.
|
||||
Well, for what we're doing, I think it'll be just fine.
|
||||
But for those of you out there listening, depending on what kind of services you're
|
||||
running and what information you're moving through those services, if you're not running
|
||||
something like WireGuard to encrypt that traffic, I think you're going to want to be careful.
|
||||
But look, it's a service that's available at no cost to the user and notice I did not
|
||||
use the word free because we are in the product.
|
||||
Indeed.
|
||||
Well, Archer, we did a great job bringing up a lot of information for the folks to have
|
||||
something to look forward to.
|
||||
You run in Proxmox on a Debian-based system.
|
||||
And with the current stats in your box, let's go ahead and do a quick reminder, you're
|
||||
going to be running at I3 with four gigs of RAM currently with an upgrade in the future,
|
||||
hopefully.
|
||||
And any other information you want to add on top of that?
|
||||
Just that the web UI is pretty user friendly.
|
||||
Now, here's hoping we can also get a little bit of containerization later on.
|
||||
We have to wait and see how that works.
|
||||
We have to first make it out the gate.
|
||||
I'll probably crash and fail and weeping the night away and switching over to Proxmox
|
||||
as well, but I won't do so without giving it a go.
|
||||
So that'll wrap it up for today's episode.
|
||||
You guys, thank you all for listening.
|
||||
I'm some guy on the internet here with I3702 and we're out of here.
