Config Ssh Password



  1. Ssh Config Password Authentication
  2. Ssh Config Password Vscode
For some oneAPI applications, you must configure a password-less SSH connection for the root user on the target system; for example:
  • IoT applications that use the MRAA/UPM sensor library
  • Any application that interacts with system resources that require su, sudo, or root access
  • Any tool that requires remote root or sudo access to your target system
When you finish the configuration steps below you will be able to “ssh into” your remote Linux target from your host development system without a password prompt, as a normal (non-root) user or as a root user.
For an introduction to SSH and how SSH keys work, see SSH Essentials: Working with SSH Servers, Clients, and Keys.
Password-less access works only when you connect to your target system from your host development system with a matching private SSH key. Attempting to connect from a different host system will still require a password.

I'm looking for a way to disable SSH clients from accessing the password prompt as noted here. I am unable to disable the password: prompt for root login. I have change the sshdconfig file to rea. I recently needed this but none of the options above worked, ssh -v showed that the command-line options passed via the -o switch were over-ridden by the values specified in my /.ssh/config file. What worked was this: ssh -F /dev/null @ From the ssh man page:-F configfile Specifies an alternative per-user configuration file. Secure Shell (SSH) is a network protocol for your Cisco devices which is more secure than Telenet. Setting a secure password is a configuration requirement for this protocol. To set up access to a Cisco switch for SSH, you will need to have a user account created on.

Without this level of protection, any user with Telnet, web, or serial port access to the switch can change the switch configuration. If you configure only an operator password, entering the operator password through telnet, web, ssh or serial port access enables full manager privileges. The settings within 'config.ssh' relate to configuring how Vagrantwill access your machine over SSH. As with most Vagrant settings, thedefaults are typically fine, but you can fine tune whatever.

These instructions apply to:
  • Linux*, Windows*, or macOS*
  • Linux
  1. Open a terminal session (CMD window on Windows) and CD to your home directory.
  2. Enter the following commands to create an .ssh directory, set the proper permissions, and CD into the new .ssh directory.

Step 3: Generate keys and copy to the target system
From this point forward the instructions apply to all host development systems (Windows, Linux, and macOS).
  1. To generate a RSA key pair with an
    empty passphrase
    (that is, do not provide a passphrase when asked), enter:
  2. To copy the new public key to your target system's home folder, enter the following, where:
    = the name used to access the target and
    target
     = the IP address or the network hostname of the target
    You should be prompted for the non-root user password for your target device.
Step 4: Confirm that a password is no longer required (non-root)
Follow this step to confirm that a password is no longer required for your non-root user.
  1. To display the target's strings, including the target's hostname as the second field in the output, enter:
Step 5: Configure password-less access to root on your target
  1. To login to the on the target using SSH and switch to the
    root user
    using sudo, enter:
    Note that the sudo command should prompt you for your target system's password.
  2. To copy the public key that you transferred to the non-root user account on the target into the root user's authorized keys file, enter:
  3. Exit twice, first from the sudo bash session, second from the ssh connection:
To test the root connection for your target, enter:
You should see a directory listing of all files located in the /root folder on your target, without the need for a login prompt.

Next: Create a New Connection and Connect to Your Target

  • Password-less access works only when you connect to your target system from your host development system with a matching private SSH key. Attempting to connect from a different host system will still require a password.
  • Make sure that you have created a project for Linux targets, and that this project is selected in the Project Explorer.
