perl-App-PersistentSSH

Kick an F<ssh> control master around on OSX using

This POE component will keep an SSH control master alive, depending on network status. It uses the OSX command line tool _scutil_ to get notification on changes to the 'State:/Network/Global/IPv4' configuration key. Whenever this key is changed 'scutil -r' will be used to check if the specified host is directly reachable (without creating a connection using e.g. PPP), and if so spawn _ssh_. If the host is not reachable, _ssh_ is stopped.
