Recent versions of OpenSSH remove support of ssh-rsa key types and host
key algorithms from the default conection configuration. Set options to
enable them and provide a configuration option which can disable them if
required.
Prior to this commit, if a windows path contained a space, the ssh
utility could not properly find the private key path and the ssh command
would fail. This commit adds some additional logic to the ssh utility to
check if a path contains '%', and if so, use the IdentityFile argument.
Otherwise it will default to passing in the private key file with '-i',
which can support paths with spaces.
As of `net-ssh` version 4.2.0, the key :paranoid has been deprecated in
favor of using :verify_host_key. This commit updates Vagrants ssh config
to use the new key, and deprecates the use of :paranoid.
Prior to this commit, a change to how the IdentityFile setting for the
ssh command broke when a path with a space was used. This commit fixes
that by quoting the path used to set the IdentityFile so that it uses
the full path instead of part of the path after the space.
Prior to this commit, there was no way to add additional ssh arguments
within a Vagrantfile for a given vagrant machine. This commit introduces
a new option extra_args that allows users to pass in a single argument
or an array of flags that will be added onto the ssh command.
This commit allows the user to configure two additional options that
were previously not configurable: Compression and DSAAuthentication.
Each config option is set as a boolean, and if left out of the config
will default to its previous behavior which is included and set to
"yes". If the user explicitly sets it to false, it will not be included
as an ssh option.
This works by now calling the `:ssh` action on the provider. This action
is allowed to do whatever it pleases, but should at some point probably
call the `SSHExec` built-in middleware.
The `SSHExec` built-in middleware was added. This uses the information
returned by `Machine#ssh_info` and uses the `Vagrant::Util::SSH` helper
to exec into the remote machine. The provider should do any work upfront
in verifying that the machine is ready to be SSHed into.
