Config Ssh Password

admin



ConfigFor 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

Config Ssh Password Change

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.

Ssh Config Password Authentication

For configuring passwordless public key authentication, see ssh-keygen. The ssh program on a host receives its configuration from either the command line or from configuration files /.ssh/config and /etc/ssh/sshconfig. Command-line options take precedence over configuration files. The user-specific configuration file /.ssh/config is used next. Config.ssh.password (string) - This sets a password that Vagrant will use to authenticate the SSH user. Note that Vagrant recommends you use key-based authentication rather than a password (see privatekeypath) below. If you use a password, Vagrant will automatically insert a keypair if. No, it is not possible. The configuration options are described in the manual page for sshconfig and there is no such option as Pass. There are no patches (at least I didn't see any during the years yet), because it is very insecure to store passwords in plain text. 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.

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.
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

For instructions to create a new connection, view existing connections, and connect to your target, see Connecting to Your Board Using an SSH/TCF Agent Connection.
  • 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.
