Preface

Secure Shell (SSH)


Secure Shell (also known as SSH) is a network service that allows you to login and access a shell remotely in a fully encrypted connection. The SSH daemon is today, the standard for UNIX system administration, after having replaced the unencrypted telnet. The most frequently used implementation of the SSH protocol is OpenSSH.

In the last few months, Microsoft has shown an implementation (at the time of writing) of OpenSSH for Windows.

Since Ansible performs SSH connections and commands in the same way any other SSH client would do, no specific configuration has been applied to the OpenSSH server.

To speed up default SSH connections, you can always enable ControlPersist and the pipeline mode, which makes Ansible faster and secure.
