def initialize(host, options = {})

  self.port = @options[:port]
end

Class Attribute Details

.servers ⇒ Object

Access the pre-configured servers. ~/.servers.yml is parsed for this. An example entry for the servers ‘foobar’ and ‘barfoo’ would look like:

---
foobar:
  address: "127.0.0.1"
  username: "foo"
  password: "bar
  port: 22
barfoo:
  address: "192.168.0.1"
  username: "bar"
  password: "foo
  port: 22

Since the parsed Hash of servers is cached, a value can be stored and the configuration file ignored if desired.
