## Online.net account
|
||
|
||
On your Online.net account via [console.online.net](https://console.online.net/), go to:
|
||
|
||
- **“Server”** dropdown menu, then **“Servers list”**.
|
||
- Click on **“Manage”** on the right.
|
||
- **“Rescue”** button.
|
||
- As operating system select **“Ubuntu 20.04 amd64”**.
|
||
- Then start the operation, you server will boot on the Ubuntu live CD.
|
||
|
||
## Dedibox server
|
||
|
||
- Log in the rescue live system through ssh with the provided ip/credentials.
|
||
- The provided Ubuntu version is outdated (Ubuntu Saucy), so the apt repositories have to be modified before Qemu could be installed:
|
||
|
||
```
|
||
$ sudo -s
|
||
# apt update
|
||
# apt install qemu-kvm
|
||
```
|
||
|
||
Fetch a FreeBSD Installer ISO image:
|
||
|
||
```shell
|
||
# cd /tmp
|
||
# wget https://download.freebsd.org/releases/ISO-IMAGES/14.2/FreeBSD-14.2-RELEASE-amd64-bootonly.iso
|
||
# wget https://download.freebsd.org/releases/ISO-IMAGES/14.2/CHECKSUM.SHA256-FreeBSD-14.2-RELEASE-amd64
|
||
# sha256sum FreeBSD-14.2-RELEASE-amd64-bootonly.iso
|
||
d063e48b81b99005c8097e60377c23fb07e4116c5f0c0b41a5dc368fc4df6bf9 FreeBSD-14.2-RELEASE-amd64-bootonly.iso
|
||
# cat CHECKSUM.SHA256-FreeBSD-14.2-RELEASE-amd64 | grep FreeBSD-14.2-RELEASE-amd64-bootonly.iso
|
||
SHA256 (FreeBSD-14.2-RELEASE-amd64-bootonly.iso) = d063e48b81b99005c8097e60377c23fb07e4116c5f0c0b41a5dc368fc4df6bf9
|
||
```
|
||
|
||
For the post-install network configuration step _(`/etc/rc.conf`)_, try to figure out now what is your NIC model ([Handbook: Locating the correct driver](https://www.freebsd.org/doc/handbook/config-network-setup.html))
|
||
|
||
```
|
||
# lspci -v | grep Ethernet
|
||
00:14.0 Ethernet controller: Intel Corporation Ethernet Connection I354 2.5 GbE Backplane (rev 03)
|
||
Subsystem: Intel Corporation Ethernet Connection I354 2.5 GbE Backplane
|
||
```
|
||
|
||
Setup NAT on the Linux host by creating a tap interface
|
||
|
||
```
|
||
ip tuntap add tap0 mode tap
|
||
ip addr add 192.168.100.1/24 dev tap0
|
||
sysctl net.ipv4.ip_forward=1
|
||
iptables -t nat -A POSTROUTING -o enp0s20 -j MASQUERADE
|
||
```
|
||
|
||
Start the FreeBSD installer through Qemu, attached to the physical server disk, with the curses UI:
|
||
|
||
```
|
||
# qemu-system-x86_64 -hda /dev/sda -cdrom FreeBSD-14.2-RELEASE-amd64-bootonly.iso -netdev tap,id=nd0,ifname=tap0,script=no,downscript=no -device virtio-net-pci,netdev=nd0 -curses -boot d
|
||
```
|
||
|
||
Configure IPv4 static IP (as there is no DHCP server on the Linux host)
|
||
- IP Address: `192.168.100.2`
|
||
- Subnet Mask: `255.255.255.0`
|
||
- default router: `192.168.100.1`
|
||
- IPv4 DNS #1: `8.8.8.8` ([Google’s public DNS](https://developers.google.com/speed/public-dns), you can check yours in `/etc/resolv.conf`)
|
||
|
||
Then
|
||
- On the **partitioning** dialog, choose **Auto (ZFS) Guided Root-on-ZFS**
|
||
- Follow installer up to the end, and when asked for **Manual Configuration**, choose **yes** to open a shell before exiting the installer.
|
||
- Configure the network, modify the files accordingly to your network setup/nic driver:
|
||
|
||
```
|
||
# /etc/rc.conf
|
||
|
||
ifconfig_igb0="DHCP"
|
||
|
||
# /etc/resolv.conf
|
||
nameserver x.x.x.x
|
||
```
