Upon acceptance the OpenSSH Server allows the connection and remote execution of any commands in the “local” terminal. This is normal for a first time connection when using a self-generated non-public certificate. As soon as the connection is starting (and if the encryption certificate is not “known”) the first time a new message pops up asking to review the certificate connection details. For example a Windows machine running the putty SSH client. This command will automatically create the necessary symbolic links.Īt this point it is time to test the OpenSSH Server connection from a different Host. Next in order to make OpenSSH Server start at every boot of the Ubuntu Server it is just a matter to enable the automatic start of its daemon:
The result would look something similar to this screenshot. The quickest way would be to issue the command: Indeed, it is also possible to use an existing public one.įirst step would be to make sure the OpenSSH Server is running. This is a self-generated and not public one. As the output of the installation is showing it also includes the creation of an encrypted key.
