What is the use of SSH pipelining in Ansible?
SSH pipelining is an Ansible feature to reduce the number of connections to a host. Ansible will normally create a temporary directory under ~/.ansible (via ssh), then for each task, copy the module source to the directory (using sftp or scp) and execute the module (ssh again). With pipelining enabled, Ansible will connect only once per task using ssh to execute python, and write the module source to its stdin.
How does SSH key work?
Ssh works by the exchange and verification of information, using public and private keys, to identify hosts and users. It then provides encryption of subsequent communication, also by the use of public/private key cryptography. SSH is designed to provide a secure method of authentication and data transport.
Is SSH public key associated with an user?
Provides information about the public Secure Shell (SSH) key that is associated with a user account for the specific file transfer protocol-enabled server (as identified by ServerId ). The information returned includes the date the key was imported, the public key contents, and the public key ID. A user can store more than one SSH public key associated with their user name on a specific server.
What is the purpose of a SSH server?
SSH, or Secure Shell, is a remote administration protocol that allows users to control and modify their remote servers over the Internet . The service was created as a secure replacement for the unencrypted Telnet and uses cryptographic techniques to ensure that all communication to and from the remote server happens in an encrypted manner.
