#### FreeCAD
|
||||
Installing FreeCAD is as easy as:
|
||||
```command
|
||||
sudo apt update
|
||||
```shell
|
||||
sudo apt update # [tl! .cmd:2]
|
||||
sudo apt install freecad
|
||||
```
|
||||
But launching `/usr/bin/freecad` caused me some weird graphical defects which rendered the application unusable. I found that I needed to pass the `LIBGL_DRI3_DISABLE=1` environment variable to eliminate these glitches:
|
||||
```command
|
||||
env 'LIBGL_DRI3_DISABLE=1' /usr/bin/freecad &
|
||||
```shell
|
||||
env 'LIBGL_DRI3_DISABLE=1' /usr/bin/freecad & # [tl! .cmd]
|
||||
```
|
||||
To avoid having to type that every time I wished to launch the app, I inserted this line at the bottom of my `~/.bashrc` file:
|
||||
```command
|
||||
```shell
|
||||
alias freecad="env 'LIBGL_DRI3_DISABLE=1' /usr/bin/freecad &"
|
||||
```
|
||||
To be able to start FreeCAD from the Chrome OS launcher with that environment variable intact, edit it into the `Exec` line of the `/usr/share/applications/freecad.desktop` file:
|
||||
```command
|
||||
sudo vi /usr/share/applications/freecad.desktop
|
||||
```shell
|
||||
sudo vi /usr/share/applications/freecad.desktop # [tl! .cmd]

Cura isn't available from the default repos so you'll need to download the AppImage from https://github.com/Ultimaker/Cura/releases/tag/4.7.1. You can do this in Chrome and then use the built-in File app to move the file into your 'My Files > Linux Files' directory. Feel free to put it in a subfolder if you want to keep things organized - I stash all my AppImages in `~/Applications/`.
|
||||
|
||||
To be able to actually execute the AppImage you'll need to adjust the permissions with 'chmod +x':
|
||||
```command
|
||||
chmod +x ~/Applications/Ultimaker_Cura-4.7.1.AppImage
|
||||
```shell
|
||||
chmod +x ~/Applications/Ultimaker_Cura-4.7.1.AppImage # [tl! .cmd]
|
||||
```
|
||||
You can then start up the app by calling the file directly:
|
||||
```command
|
||||
~/Applications/Ultimaker_Cura-4.7.1.AppImage &
|
||||
```shell
|
||||
~/Applications/Ultimaker_Cura-4.7.1.AppImage & # [tl! .cmd]
|
||||
```
|
||||
AppImages don't automatically appear in the Chrome OS launcher so you'll need to create its `.desktop` file. You can do this manually if you want, but I found it a lot easier to leverage `menulibre`:
|
||||
```command
|
||||
sudo apt update && sudo apt install menulibre
|
||||
```shell
|
||||
sudo apt update && sudo apt install menulibre # [tl! .cmd:2]
|
||||
menulibre
|
||||
```
|
||||
Just plug in the relevant details (you can grab the appropriate icon [here](https://github.com/Ultimaker/Cura/blob/master/icons/cura-128.png)), hit the filing cabinet Save icon, and you should then be able to search for Cura from the Chrome OS launcher.

|
||||
*Steps taken from [here](https://certbot.eff.org/instructions?ws=other&os=debianbuster).*
|
||||
1. Install Certbot:

||||
3. Create a directory to store the new certificates and copy them there:

||||
```command
|
||||
sudo mkdir -p /ssl/keys/
|
||||
sudo cp -p /etc/letsencrypt/live/[FQDN]/fullchain.pem /ssl/keys/

As long as the dvPortGroup names stick to this format I can parse the name to come up with a description as well as the IP space of the network. The dvPortGroup also carries information about the associated VLAN, which is useful information to have. And I can easily export this information with a simple PowerCLI query:

In my [homelab](/vmware-home-lab-on-intel-nuc-9/), I only have a single vCenter. In production, we've got a handful of vCenters, and each manages the hosts in a given region. So I can use information about which vCenter hosts a dvPortGroup to figure out which region a network is in. When I import this data into phpIPAM, I can use the vCenter name to assign [remote scan agents](https://github.com/jbowdre/phpipam-agent-docker) to networks based on the region that they're in. I can also grab information about which virtual datacenter a dvPortGroup lives in, which I'll use for grouping networks into sites or sections.
|
||||
|
||||
The vCenter can be found in the `Uid` property returned by `get-vdportgroup`:

|
||||
```command
|
||||
ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519_wireguard
|

#### WireGuard Server Setup
|
||||
Once the **Compute Engine > Instances** [page](https://console.cloud.google.com/compute/instances) indicates that the instance is ready, I can make a note of the listed public IP and then log in via SSH:
|
||||
```command
|
||||
ssh -i ~/.ssh/id_25519_wireguard {PUBLIC_IP}
|
||||
```shell
|
||||
ssh -i ~/.ssh/id_25519_wireguard {PUBLIC_IP} # [tl! .cmd]
|
||||
```
|
||||
|
||||
##### Preparation
|
||||
And, as always, I'll first make sure the OS is fully updated before doing anything else:
|
||||
```command
|
||||
sudo apt update
|
||||
```shell
|
||||
sudo apt update # [tl! .cmd:1]
|
||||
sudo apt upgrade
|
||||
```
|
||||
|
||||
Then I'll install `ufw` to easily manage the host firewall, `qrencode` to make it easier to generate configs for mobile clients, `openresolv` to avoid [this issue](https://superuser.com/questions/1500691/usr-bin-wg-quick-line-31-resolvconf-command-not-found-wireguard-debian/1500896), and `wireguard` to, um, guard the wires:
|
||||
```command
|
||||
sudo apt install ufw qrencode openresolv wireguard
|
||||
```shell
|
||||
sudo apt install ufw qrencode openresolv wireguard # [tl! .cmd]
|
||||
```
|
||||
|
||||
Configuring the host firewall with `ufw` is very straight forward:
|
||||
```shell
|
||||
# First, SSH:
|
||||
sudo ufw allow 22/tcp
|
||||
# and WireGuard:
|
||||
sudo ufw allow 51820/udp
|
||||
# Then turn it on:
|
||||
sudo ufw enable
|
||||
# First, SSH: # [tl! .nocopy]
|
||||
sudo ufw allow 22/tcp # [tl! .cmd]
|
||||
# and WireGuard: # [tl! .nocopy]
|
||||
sudo ufw allow 51820/udp # [tl! .cmd]
|
||||
# Then turn it on: # [tl! .nocopy]
|
||||
sudo ufw enable # [tl! .cmd]
|
||||
```
|
||||
|
||||
The last preparatory step is to enable packet forwarding in the kernel so that the instance will be able to route traffic between the remote clients and my home network (once I get to that point). I can configure that on-the-fly with:
|
||||
```command
|
||||
sudo sysctl -w net.ipv4.ip_forward=1
|
||||
```shell
|
||||
sudo sysctl -w net.ipv4.ip_forward=1 # [tl! .cmd]
|
||||
```
|
||||
|
||||
To make it permanent, I'll edit `/etc/sysctl.conf` and uncomment the same line:
|
||||
```command
|
||||
sudo vi /etc/sysctl.conf
|
||||
```shell
|
||||
sudo vi /etc/sysctl.conf # [tl! .cmd]
|
||||
```
|
||||
```cfg
|
||||
```ini
|
||||
# Uncomment the next line to enable packet forwarding for IPv4
|
||||
net.ipv4.ip_forward=1
|
||||
```
|
||||
|
||||
##### WireGuard Interface Config
|
||||
I'll switch to the root user, move into the `/etc/wireguard` directory, and issue `umask 077` so that the files I'm about to create will have a very limited permission set (to be accessible by root, and _only_ root):
|
||||
```command
|
||||
sudo -i
|
||||
cd /etc/wireguard
|
||||
```shell
|
||||
sudo -i # [tl! .cmd]
|
||||
cd /etc/wireguard # [tl! .cmd_root:1]
|
||||
umask 077
|
||||
```
|
||||
|
||||
Then I can use the `wg genkey` command to generate the server's private key, save it to a file called `server.key`, pass it through `wg pubkey` to generate the corresponding public key, and save that to `server.pub`:
|
||||
```command
|
||||
wg genkey | tee server.key | wg pubkey > server.pub
|
||||
```shell
|
||||
wg genkey | tee server.key | wg pubkey > server.pub # [tl! .cmd_root]
|
||||
```
|
||||
|
||||
As I mentioned earlier, WireGuard will create a virtual network interface using an internal network to pass traffic between the WireGuard peers. By convention, that interface is `wg0` and it draws its configuration from a file in `/etc/wireguard` named `wg0.conf`. I could create a configuration file with a different name and thus wind up with a different interface name as well, but I'll stick with tradition to keep things easy to follow.
|
||||
|
||||
The format of the interface configuration file will need to look something like this:
|
||||
```cfg
|
||||
```ini
|
||||
# torchlight! {"lineNumbers": true}
|
||||
[Interface] # this section defines the local WireGuard interface
|
||||
Address = # CIDR-format IP address of the virtual WireGuard interface
|
||||
ListenPort = # WireGuard listens on this port for incoming traffic (randomized if not specified)
|
||||
|
|
@ -164,7 +165,8 @@ AllowedIPs = # which IPs will be routed to this peer
|
|||
There will be a single `[Interface]` section in each peer's configuration file, but they may include multiple `[Peer]` sections. For my config, I'll use the `10.200.200.0/24` network for WireGuard, and let this server be `10.200.200.1`, the VyOS router in my home lab `10.200.200.2`, and I'll assign IPs to the other peers from there. I found a note that Google Cloud uses an MTU size of `1460` bytes so that's what I'll set on this end. I'm going to configure WireGuard to use the VyOS router as the DNS server, and I'll specify my internal `lab.bowdre.net` search domain. Finally, I'll leverage the `PostUp` and `PostDown` directives to enable and disable NAT so that the server will be able to forward traffic between networks for me.
|
||||
|
||||
So here's the start of my GCP WireGuard server's `/etc/wireguard/wg0.conf`:
|
||||
```cfg
|
||||
```ini
|
||||
# torchlight! {"lineNumbers": true}
|
||||
# /etc/wireguard/wg0.conf
|

||||
I don't have any other peers ready to add to this config yet, but I can go ahead and bring up the interface all the same. I'm going to use the `wg-quick` wrapper instead of calling `wg` directly since it simplifies a bit of the configuration, but first I'll need to enable the `wg-quick@{INTERFACE}` service so that it will run automatically at startup:
|
||||
```command
|
||||
systemctl enable wg-quick@wg0
|
||||
```shell

systemctl enable wg-quick@wg0 # [tl! .cmd_root:1]

### Configure VyoS Router as WireGuard Peer
|
||||
Comparatively, configuring WireGuard on VyOS is a bit more direct. I'll start by entering configuration mode and generating and binding a key pair for this interface:
|
||||
```commandroot
|
||||
configure
|
||||
```shell
|
||||
configure # [tl! .cmd_root:1]
|
||||
run generate pki wireguard key-pair install interface wg0
|
||||
```
|
||||
|
||||
And then I'll configure the rest of the options needed for the interface:
|
||||
```commandroot
|
||||
set interfaces wireguard wg0 address '10.200.200.2/24'
|
||||
```shell
|
||||
set interfaces wireguard wg0 address '10.200.200.2/24' # [tl! .cmd_root:start]
|
||||
set interfaces wireguard wg0 description 'VPN to GCP'
|
||||
set interfaces wireguard wg0 peer wireguard-gcp address '{GCP_PUBLIC_IP}'
|
||||
set interfaces wireguard wg0 peer wireguard-gcp allowed-ips '0.0.0.0/0'
|
||||
set interfaces wireguard wg0 peer wireguard-gcp persistent-keepalive '25'
|
||||
set interfaces wireguard wg0 peer wireguard-gcp port '51820'
|
||||
set interfaces wireguard wg0 peer wireguard-gcp public-key '{GCP_PUBLIC_KEY}'
|
||||
set interfaces wireguard wg0 peer wireguard-gcp public-key '{GCP_PUBLIC_KEY}' # [tl! .cmd_root:end]
|
||||
```
|
||||
|
||||
Note that this time I'm allowing all IPs (`0.0.0.0/0`) so that this WireGuard interface will pass traffic intended for any destination (whether it's local, remote, or on the Internet). And I'm specifying a [25-second `persistent-keepalive` interval](https://www.wireguard.com/quickstart/#nat-and-firewall-traversal-persistence) to help ensure that this NAT-ed tunnel stays up even when it's not actively passing traffic - after all, I'll need the GCP-hosted peer to be able to initiate the connection so I can access the home network remotely.
|
||||
|
||||
While I'm at it, I'll also add a static route to ensure traffic for the WireGuard tunnel finds the right interface:
|
||||
```commandroot
|
||||
set protocols static route 10.200.200.0/24 interface wg0
|
||||
```shell
|
||||
set protocols static route 10.200.200.0/24 interface wg0 # [tl! .cmd_root]
|
||||
```
|
||||
|
||||
And I'll add the new `wg0` interface as a listening address for the VyOS DNS forwarder:
|
||||
```commandroot
|
||||
set service dns forwarding listen-address '10.200.200.2'
|
||||
```shell
|
||||
set service dns forwarding listen-address '10.200.200.2' # [tl! .cmd_root]
|
||||
```
|
||||
|
||||
I can use the `compare` command to verify the changes I've made, and then apply and save the updated config:
|
||||
```commandroot
|
||||
compare
|
||||
```shell
|
||||
compare # [tl! .cmd_root:2]
|
||||
commit
|
||||
save
|
||||
```
|
||||
|
||||
I can check the status of WireGuard on VyOS (and view the public key!) like so:
|
||||
```commandroot-session
|
||||
show interfaces wireguard wg0 summary
|
||||
interface: wg0
|
||||
```shell
|
||||

See? That part was much easier to set up! But it doesn't look like it's actually passing traffic yet... because while the VyOS peer has been configured with the GCP peer's public key, the GCP peer doesn't know anything about the VyOS peer yet.
|
||||
|
||||
So I'll copy `{VYOS_PUBLIC_KEY}` and SSH back to the GCP instance to finish that configuration. Once I'm there, I can edit `/etc/wireguard/wg0.conf` as root and add in a new `[Peer]` section at the bottom, like this:

|

This time, I'm telling WireGuard that the new peer has IP `10.200.200.2` but that it should also get traffic destined for the `192.168.1.0/24` and `172.16.0.0/16` networks, my home and lab networks. Again, the `AllowedIPs` parameter is used for WireGuard's Cryptokey Routing so that it can keep track of which traffic goes to which peers (and which key to use for encryption).
|
||||
|
||||
After saving the file, I can either restart WireGuard by bringing the interface down and back up (`wg-quick down wg0 && wg-quick up wg0`), or I can reload it on the fly with:
|
||||
```command
|
||||
sudo -i
|
||||
wg syncconf wg0 <(wg-quick strip wg0)
|
||||
```shell
|
||||
sudo -i # [tl! .cmd]
|
||||
wg syncconf wg0 <(wg-quick strip wg0) # [tl! .cmd_root]
|
||||
```
|
||||
|
||||
(I can't just use `wg syncconf wg0` directly since `/etc/wireguard/wg0.conf` includes the `PostUp`/`PostDown` commands which can only be parsed by the `wg-quick` wrapper, so I'm using `wg-quick strip {INTERFACE}` to grab the contents of the config file, remove the problematic bits, and then pass what's left to the `wg syncconf {INTERFACE}` command to update the current running config.)

Being able to copy-and-paste the required public keys between the WireGuard app and the SSH session to the GCP instance made it relatively easy to set up the Chromebook, but things could be a bit trickier on a phone without that kind of access. So instead I will create the phone's configuration on the WireGuard server in the cloud, render that config file as a QR code, and simply scan that through the phone's WireGuard app to import the settings.
|
||||
|
||||
I'll start by SSHing to the GCP instance, elevating to root, setting the restrictive `umask` again, and creating a new folder to store client configurations.

cd /etc/wireguard/clients

```shell
|
||||
sudo apt install virt-manager libvirt-dev # [tl! .cmd]

### Install Vagrant

|
||||
```command
|
||||
wget -O- https://apt.releases.hashicorp.com/gpg | gpg --dearmor | sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg

||||
```
|
||||
|
||||
I'll then install the Vagrant package:

||||
```command
|
||||
sudo apt update
|
||||
```shell
|
||||
sudo apt update # [tl! .cmd:1]

||||
sudo apt install vagrant
|
||||

||||
|
||||
I also need to install the [`vagrant-libvirt` plugin](https://github.com/vagrant-libvirt/vagrant-libvirt) so that Vagrant will know how to interact with `libvirt`:

||||

||||

For my first VM, I'll go with something light and simple: [`generic/alpine38`](https://app.vagrantup.com/generic/boxes/alpine38).
|
||||
|
||||
So I'll create a new folder to contain the Vagrant configuration:
|
||||
```command
|
||||
mkdir vagrant-alpine
|
||||
```shell
|
||||
mkdir vagrant-alpine # [tl! .cmd:1]
|
||||
cd vagrant-alpine
|
||||
```
|
||||
|
||||
And since I'm referencing a Vagrant Box which is published on Vagrant Cloud, downloading the config is as simple as:
|
||||
```command
|
||||
vagrant init generic/alpine38
|
||||
```
|
||||
|
||||
That lets me know that
|
||||

Before I `vagrant up` the joint, I do need to make a quick tweak to the default Vagrantfile, which is what tells Vagrant how to configure the VM. By default, Vagrant will try to create a synced folder using NFS and will throw a nasty error when that (inevitably[^inevitable]) fails. So I'll open up the Vagrantfile to review and edit it:
|
||||
```command
|
||||
vim Vagrantfile
|
||||
```shell
|
||||
vim Vagrantfile # [tl! .cmd]
|
||||
```
|
||||
|
||||
Most of the default Vagrantfile is commented out. Here's the entirey of the configuration *without* the comments:

There's not a lot there, is there? Well I'm just going to add these two lines somewhere between the `Vagrant.configure()` and `end` lines:
|
||||
```ruby
|
||||
config.nfs.verify_installed = false
|
||||
Vagrant.configure("2") do |config|
|

config.vm.box = "generic/alpine38"

|
||||
config.vm.synced_folder '.', '/vagrant', type: 'rsync'
|
||||
end
|
||||
```
|
||||
|
||||
The first line tells Vagrant not to bother checking to see if NFS is installed, and will use `rsync` to share the local directory with the VM guest, where it will be mounted at `/vagrant`.

With that, I'm ready to fire up this VM with `vagrant up`! Vagrant will look inside `Vagrantfile` to see the config, pull down the `generic/alpine38` Box from Vagrant Cloud, boot the VM, configure it so I can SSH in to it, and mount the synced folder:
|
||||
```command-session

Once I'm finished poking at this VM, shutting it down is as easy as:
|
||||
```command
|
||||
vagrant halt
|
||||
```shell
|
||||
vagrant halt # [tl! .cmd]
|
||||
```
|
||||
|
||||
And if I want to clean up and remove all traces of the VM, that's just:
|
||||
```command
|
||||
vagrant destroy
|
||||
```shell

||||
vagrant destroy # [tl! .cmd]

Now it's time to bring it up. This one's going to take A While as it syncs the ~12GB Box first.

Eventually it should spit out that lovely **Machine booted and ready!** message and I can log in! I *can* do a `vagrant ssh` again to gain a shell in the Windows environment, but I'll probably want to interact with those sweet sweet graphics. That takes a little bit more effort.

```command

I log in with the default password `vagrant`, and I'm in Windows 11 land!
