## Serial Console Linux distribution availability

For the serial console to function properly, the guest operating system must be configured to read and write console messages to the serial port. Most [Endorsed Azure Linux distributions](https://docs.microsoft.com/azure/virtual-machines/linux/endorsed-distros) have the serial console configured by default. Selecting **Serial console** in the **Support + troubleshooting** section of the Azure portal provides access to the serial console.

Custom Linux images | To enable the serial console for your custom Linux VM image, enable console access in the file */etc/inittab* to run a terminal on `ttyS0`. For example: `S0:12345:respawn:/sbin/agetty -L 115200 console vt102`. For more information on properly creating custom images, see [Create and upload a Linux VHD in Azure](https://aka.ms/createuploadvhd). If you're building a custom kernel, consider enabling these kernel flags: `CONFIG_SERIAL_8250=y` and `CONFIG_MAGIC_SYSRQ_SERIAL=y`. The configuration file is typically located in the */boot/* path.

2020
A virtual network gateway is composed of two or more virtual machines that are deployed to a specific subnet you create, which is called the *gateway subnet*. The VMs that are located in the gateway subnet are created when you create the virtual network gateway. Virtual network gateway VMs are configured to contain routing tables and gateway services specific to the gateway. You can't directly configure the VMs that are part of the virtual network gateway and you should never deploy additional resources to the gateway subnet.

Creating a virtual network gateway can take up to 45 minutes to complete. When you create a virtual network gateway, gateway VMs are deployed to the gateway subnet and configured with the settings that you specify. One of the settings you configure is the gateway type. The gateway type 'vpn' specifies that the type of virtual network gateway created is a VPN gateway. After you create a VPN gateway, you can create an IPsec/IKE VPN tunnel connection between that VPN gateway and another VPN gateway (VNet-to-VNet), or create a cross-premises IPsec/IKE VPN tunnel connection between the VPN gateway and an on-premises VPN device (Site-to-Site). You can also create a Point-to-Site VPN connection (VPN over IKEv2 or SSTP), which lets you connect to your virtual network from a remote location, such as from a conference or from home.
