Description
When Rex::Config parses ~/.ssh/config it slurps options for named servers, but not for the all hosts "*" option. This means that it is not possible to set a configuration value for all hosts in the config file, and instead Rex sets its default. (In my case, I was trying to specify a default timeout value).
I've worked around this by adding the following in my Rexfile: Rex::Config->set_timeout(20); but I wanted to note it here for the record.
It doesn't look like an easy fix unfortunately, as each configuration option is taken from a hash for the host in question.

Research direction
Start at Rex::Config's parser for ~/.ssh/config and trace how options are selected for a named host. Confirm that values under the '*' host are included in the effective configuration, including the timeout example, and verify the behavior against a representative SSH config.
