This article provides an overview of running a FreeBSD virtual machine in Azure.
If a passphrase is used in ssh-keygen (1), the user will be prompted for a password each time in order to use the private key. A SSH protocol version 2 DSA key can be created for the same purpose by using the ssh-keygen -t dsa command. This will create a public/private DSA key for use in SSH protocol version 2 sessions only. Generating the key. First generate a key on the FreeBSD/OpenBSD box like so: Note: When creating a key, the program will ask you for a pass phrase for this key, you may or may not want to use one. If you do then you'll have to enter in your pass phrase whenever using Putty to log in. Using your ssh3 key with Putty. Pick a host and pick 'ssh. SSH utilizes a key fingerprint system to verify the authenticity of the server when the client connects. When the user accepts the key's fingerprint by typing yes when connecting for the first time, a copy of the key is saved to.ssh/knownhosts in the user's home directory. Normally, when using telnet (1) or rlogin (1), data is sent over the network in an clear, un-encrypted form.Network sniffers anywhere in between the client and server can steal your user/password information or data transferred in your session.
Overview
FreeBSD for Microsoft Azure is an advanced computer operating system used to power modern servers, desktops, and embedded platforms.

Microsoft Corporation is making images of FreeBSD available on Azure with the Azure VM Guest Agent pre-configured. Currently, the following FreeBSD versions are offered as images by Microsoft:
The agent is responsible for communication between the FreeBSD VM and the Azure fabric for operations such as provisioning the VM on first use (user name, password or SSH key, host name, etc.) and enabling functionality for selective VM extensions.

As for future versions of FreeBSD, the strategy is to stay current and make the latest releases available shortly after they are published by the FreeBSD release engineering team.
Create a FreeBSD VM through Azure CLI on FreeBSD
First you need to install Azure CLI though following command on a FreeBSD machine.
If bash is not installed on your FreeBSD machine, run following command before the installation.
If python is not installed on your FreeBSD machine, run following commands before the installation.
During the installation, you are asked
Modify profile to update your $PATH and enable shell/tab completion now? (Y/n)
. If you answer y
and enter /etc/rc.conf
as a path to an rc file to update
, you may meet the problem ERROR: [Errno 13] Permission denied
. To resolve this problem, you should grant the write right to current user against the file etc/rc.conf
.Now you can sign in to Azure and create your FreeBSD VM. Below is an example to create a FreeBSD 11.0 VM. You can also add the parameter
--public-ip-address-dns-name
with a globally unique DNS name for a newly created Public IP.Then you can sign in to your FreeBSD VM through the ip address that printed in the output of above deployment.

VM extensions for FreeBSD
Following are supported VM extensions in FreeBSD.
VMAccess
The VMAccess extension can:
- Reset the password of the original sudo user.
- Create a new sudo user with the password specified.
- Set the public host key with the key given.
- Reset the public host key provided during VM provisioning if the host key is not provided.
- Open the SSH port (22) and restore the sshd_config if reset_ssh is set to true.
- Remove the existing user.
- Check disks.
- Repair an added disk.
CustomScript
The CustomScript extension can:
- If provided, download the customized scripts from Azure Storage or external public storage (for example, GitHub).
- Run the entry point script.
- Support inline commands.
- Convert Windows-style newline in shell and Python scripts automatically.
- Remove BOM in shell and Python scripts automatically.
- Protect sensitive data in CommandToExecute.
Note
FreeBSD VM only supports CustomScript version 1.x by now.
Authentication: user names, passwords, and SSH keys
When you're creating a FreeBSD virtual machine by using the Azure portal, you must provide a user name, password, or SSH public key.User names for deploying a FreeBSD virtual machine on Azure must not match names of system accounts (UID <100) already present in the virtual machine ('root', for example).Currently, only the RSA SSH key is supported. A multiline SSH key must begin with
---- BEGIN SSH2 PUBLIC KEY ----
and end with ---- END SSH2 PUBLIC KEY ----
.Obtaining superuser privileges
The user account that is specified during virtual machine instance deployment on Azure is a privileged account. The package of sudo was installed in the published FreeBSD image.After you're logged in through this user account, you can run commands as root by using the command syntax.
You can optionally obtain a root shell by using
sudo -s
.Known issues

The Azure VM Guest Agent version 2.2.2 has a known issue that causes the provision failure for FreeBSD VM on Azure. The fix was captured by Azure VM Guest Agent version 2.2.3 and later releases.
