*Do not proceed any further if you do not yet meet these requirements.*

First, **attach** the VM you want to expose to the network
|

First, attach the VM you want to expose to the network
|
||||
to a NetVM that has an active network connection:
|
||||
|
||||
`qvm-prefs -s testvm netvm sys-net`
|
||||
|
||||
Set an **IP** address on `testvm` belonging to the same LAN as `sys-net`:
|
||||
Then, set an IP address on the VM:
|
||||
|
||||
`qvm-prefs -s testvm ip 192.168.16.25`
|
||||
|
||||
**Restart** the `testvm` VM if it was already running.
|

(The step above requires you restart the `testvm` VM if it was running.)
|
||||
|

**Configure** routing method; to enable the network server feature for
|

your `testvm` VM, all you have to do in your AdminVM (`dom0`) is run

the following command:
|

Then, to enable the network server feature for your `testvm` VM, all you have
|
||||
to do in your AdminVM (`dom0`) is run the following command:
|
||||
|
||||
`qvm-features testvm routing-method forward`
|
||||
|
||||
Now `testvm` is exposed to the network with address `192.168.16.25`, as well
|
||||
as to other VMs attached to `NetVM`.
|
||||
|
||||
Finally, adjust **input firewall rules** on `testvm` to permit traffic coming from
|
||||
machines in your LAN. `testvm` will have the standard Qubes OS firewall
|
||||
rules stopping inbound traffic. To solve that issue, you can use a sample
|

rule in `testvm`:
|
||||
|
||||
```
|
||||
sudo nft add rule qubes custom-input ip saddr 192.168.16.0/24 ct state new,established,related counter accept
|
||||
```
|
||||
|
||||
You can make these rules persistent by [following instructions on the Qubes
|
||||
OS firewall documentation page](https://www.qubes-os.org/doc/firewall/#enabling-networking-between-two-qubes).
|
||||
Note that you do not need to change the `custom-forward` chain at all
|
||||
on any qube -- Qubes network server manages that for you transparently
|
||||
in your `NetVM`.
|
||||
Do note that `testvm` will have the standard Qubes OS firewall rules stopping
|
||||
inbound traffic. To solve that issue, you can
|
||||
[use the standard `rc.local` Qubes OS mechanism to alter the firewall rules](https://www.qubes-os.org/doc/firewall/#where-to-put-firewall-rules)
|
||||
in your `testvm` AppVM.

### How to build the packages to install
|
||||
|
||||
You will first build the `qubes-core-admin-addon-network-server` RPM.
|
||||
|
||||
To build this package, you will need to use a `chroot` jail containing
|
||||
a Fedora installation of the exact same release as your `dom0` (Fedora 37
|
||||
for Qubes 4.2). You can do this using `toolbox` (for maximum safety
|
||||
within a disposable qube):
|
||||
a Fedora installation of the exact same release as your `dom0` (Fedora 25
|
||||
for Qubes release 4.0, Fedora 32 for Qubes release 4.1).
|
||||
|
||||
```
|
||||
dnf install -y toolbox
|
||||
toolbox create -r 37
|
||||
toolbox enter fedora-toolbox-37
|
||||
# Bam! You have a shell in an isolated Fedora 37 instance now.
|
||||
```
|
||||
Copy the source of the package to your `chroot`. Then start a shell in
|
||||
your `chroot`, and type `make rpm`. You may have to install some packages
|
||||
in your `chroot` -- use `dnf install git rpm-build make coreutils tar gawk findutils systemd systemd-rpm-macros`
|
||||
to get the minimum dependency set installed.
|
||||
|
||||
Within the toolbox, all your normal files from your home directory are
|
||||
visible. Change into the directory that contains this source code,
|
||||
then type `make rpm`. You may have to install some packages within your
|
||||
toolbox -- use `dnf install git rpm-build make coreutils tar gawk findutils systemd systemd-rpm-macros`
|
||||
to get the minimum dependency set installed. Don't worry -- nothing within
|
||||
the toolbox affects
|
||||
Once built, in the source directory you will find the RPM built for the
|
||||
exact release of Qubes you need.
|
||||
|
||||
Once built, in the source directory you will find the
|
||||
`qubes-core-admin-addon-network-server` RPM built for your dom0.
|
||||
Alternatively, you may first create a source RPM using `make srpm` on your
|
||||
regular workstation, then use `mock` to rebuild the source RPM produced
|
||||
in the source directory, using a Fedora release compatible with your `dom0`.
|
||||
|
||||
To build the `qubes-network-server` RPM that goes in your template, you
|

can simply use a DisposableVM running the same Fedora release as your NetVM.

# How to upgrade a Qubes network server from Qubes OS 4.1 to Qubes OS 4.2
|
||||
|
||||
The [standard instructions to upgrade Qubes OS systems](https://www.qubes-os.org/doc/upgrade/4.2/)
|
||||
will fail to work. The instructions tell you to run something to the effect of:
|
||||
|
||||
```
|
||||
qubes-dist-upgrade --all-pre-reboot <other flags>
|
||||
```
|
||||
|
||||
then reboot, then run:
|
||||
|
||||
```
|
||||
qubes-dist-upgrade --all-post-reboot <other flags>
|
||||
```
|
||||
|
||||
The pre-reboot phase will fail if run without the following precautions.
|
||||
|
||||
## Step by step instructions
|
||||
|
||||
First, build a `qubes-network-server` RPM with the instructions provided
|
||||
by this package's [README.md](../README.md) file. Then, for each template
|
||||
where `qubes-network-server` is installed, deposit your build of the
|
||||
`qubes-network-server` RPM in a folder `/root/update` of the template,
|
||||
and run the command `createrepo_c /root/update` (you may have to install
|
||||
package `createrepo_c` via `dnf` to run it).
|
||||
|
||||
Now build a `qubes-core-admin-addon-network-server` package for your dom0,
|
||||
then copy the file to your profile directory into dom0. Remember this
|
||||
package has to be built *in the same Fedora release (37)* as the Qubes OS
|
||||
4.2 dom0 (the `toolbox` command in a disposable qube is handy for this!).
|
||||
|
||||
Now open the file `/etc/dnf/dnf.conf` on every template qube where you
|
||||
did the above, then add an `exclude=qubes-network-server` setting under
|
||||
its `[main]` section.
|
||||
|
||||
Remove the currently-installed `qubes-core-admin-addon-network-server`
|
||||
package from your dom0 (using `dnf remove`).
|
||||
|
||||
Run the pre-reboot phase.
|
||||
|
||||
Install the recently-built `qubes-core-admin-addon-network-server` package
|
||||
into dom0 (using `dnf install` with the path to the RPM file).
|
||||
|
||||
Reboot.
|
||||
|
||||
Before running the post-reboot phase, remove the setting you added to the
|
||||
`dnf.conf` file of each template you modified. Finally, add the file
|
||||
`/etc/yum.repos.d/local.repo` with the following contents:
|
||||
|
||||
```
|
||||
[local]
|
||||
name=Local packages
|
||||
baseurl=file:///root/update
|
||||
enabled=1
|
||||
gpgcheck=0
|
||||
metadata_expire=15
|
||||
```
|
||||
|
||||
Now run the post-reboot phase. The template upgrade should succeed now.
|
||||
|
||||
To finalize, delete folder `/root/update` and file `/etc/yum.repos.d/local.repo`
|
||||
from every template that has it.
|
||||
|
||||
You are now updated to Qubes OS 4.2 and `qubes-network-server` is ready.
