The Azure portal or Azure CLI act as remote terminals to the virtual machine serial port. As these terminals can't directly connect to the servers which host the virtual machine over the network, an intermediate service gateway is used to proxy the terminal traffic. Azure Serial Console doesn't store or process this customer data. The intermediate service gateway that transfers the data will reside in the geography of the virtual machine.
No access passwords for the console are logged. However, if commands run within the console contain or output passwords, secrets, user names, or any other form of personally identifiable information (PII), those will be written to the VM boot diagnostics logs. They will be written along with all other visible text as part of the implementation of the serial console's scroll back function. These logs are circular, and only individuals with read permissions to the diagnostics storage account have access to them. If you are inputting any data or commands that contain secrets or PII, we would recommend using SSH unless the serial console is absolutely necessary.
"I accidentally deleted some files on my Macbook and attempted to use Disk Drill to retrieve them back. The free "basic" version lets me wait a full 8-9 hours to see the data is there, then it tells me I can't recover a single file without purchasing a serial key for the PRO version. Is Disk Drill really free? I'm a sophomore high-school student and I don't have the money to pay. So, is there any free Disk Drill alternative software that can help?"
If no file systems are found, you have other options to try to rescue your data. The photorec application is designed to help recover many different types of lost files. For more information about photorec, see
When you are finished rescuing data, click Close to end this attempt to rescue data. The application umounts any file systems that were mounted for viewing. Then the application rescans all the disk devices and refreshes the device partition layout in the gparted window.
To perform this task, you must have the following permissions: compute.instances.setMetadata on the VM if enabling interactive access on a specific VM compute.projects.setCommonInstanceMetadata on the project, if enabling interactive access for all VMs in the project iam.serviceAccountUser role on the instance's service account Enabling interactive access on the serial consoleEnable interactive serial console access for individual VM instances or foran entire project.
The serial console authenticates users withSSH keys. Specifically, you must add yourpublic SSH key to the project or instance metadata and store your private keyon the local machine from which you want to connect. The gcloud CLIand the Google Cloud console automatically add SSH keys to the project for you.If you are using a third-party client, you might need to add SSH keys manually.
Login prompts are enabled on port 1 by default on most Linux operating systems.However, port 1 can often be overwhelmed by logging data and other informationbeing printed to the port. Instead, you can choose to enable a loginprompt on another port, such as port 2 (ttyS1), by executing one ofthe following commands on your VM. You can see a list of availableports for an VM inUnderstanding serial port numbering.
You can disable interactive serial console access by changing metadata on thespecific instance or project, or by setting anOrganization Policy thatdisables interactive serial console access to all VM instances for one or moreprojects that are part of the organization.
Project owners and editors, as well as users who have been granted thecompute.instanceAdmin.v1 role, can disable access to the serial console bychanging the metadata on the particular instance or project. Similar toenabling serial console access,set the serial-port-enable metadata to FALSE:
If you have been granted the orgpolicy.policyAdmin role on the organization,you can set anorganization policythat prevents interactive access to the serial console, regardless of whetherinteractive serial console access is enabled on the metadata server. After theorganization policy is set, the policy effectively overrides theserial-port-enable metadata key,and no users of the organization or project can enable interactive serialconsole access. By default, this constraint is set to FALSE.
By default, each time you connect to the serial console, you will receivea replay of the last 10 lines of data, regardless of whether the last 10 lineshave been seen by another SSH client. You can change this setting and controlhow many and which lines are returned by setting the following options:
The most recent 1 MiB of output for each serial port is always available andgenerally, your SSH client should not miss any output from the serial port.If, for some reason, your SSH client stops accepting output for a period oftime but does not disconnect, and more than 1 MiB of new data is produced,your SSH client might miss some output. When your SSHclient is not accepting data fast enough to keep up with the output on theserial console port, you can set the on-dropped-output property to determinehow the console behaves.
Description: SystemRescue (formerly known as SystemRescueCd) is a Linuxsystem rescue toolkit available as a bootable medium for administrating orrepairing your system and data after a crash. It aims to provide an easy way tocarry out admin tasks on your computer, such as creating and editing the harddisk partitions. It comes with a lot of Linux system utilitiessuch as GParted, fsarchiver, filesystem tools and basic tools (editors, midnightcommander, network tools). It can be used for both Linuxand windowscomputers, and on desktops as well as servers. This rescue system requires noinstallation as it can be booted from a CD/DVD drive orUSB stick, but it can beinstalled on the hard diskif you wish. The kernel supports all important file systems (ext4, xfs, btrfs,vfat, ntfs), as well as network filesystems such as Samba and NFS.
The LoSSI standard allows issuing of commands to peripherals (LCD) and to transfer data to and from them. LoSSI commands and parameters are 8 bits long, but an extra bit is used to indicate whether the byte is a command or parameter/data. This extra bit is set high for a data and low for a command. The resulting 9-bit value is serialized to the output. LoSSI is commonly used with MIPI DBI type C compatible LCD controllers. 2b1af7f3a8
