Adds a new `key_type` option to the Vagrantfile ssh configuration. It
defaults to :auto which allows auto detection of key type to use.
Otherwise it can be set to an explicit type supported by Vagrant.
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.
Retains the original default value of 15 seconds for SSH connect
timeout. Allows users to modify this timeout via SSH communicator
option. Enforces integer values for timeout and validates custom
values are greater than 0.
Include config option within ssh_config command output template. Default
remote_user value to set username value. Include existence check on
provided config value to ensure file is available. Update tests to
include coverage on all changes. Add new options to the docs.
Also noticed whilst testing that if the `ProxyCommand` uses `%r`, then
it fails with `unable to find remote user`, so added support for
`config.ssh.remote_user` aswell
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, 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 adds two new SSH configuration options:
- `keys_only`
- `paranoid`
These values were previously hard-coded, but can now be user-specified.
Fixes GH-4275
