my idea is
* add new variable in the configuration
set :gateway {..}
set :default_connect_direct, true # new variable
* modify connect_to() method in GatewayConnectionFactory class
def connet_to(server)
+ if fetch(:default_connect_direct, false) && !@gateways[server.host]
+ SSH.connect(server, @options)
+ else
# original
+ end
end
I expect that the client connects to server directly if
:default_connect_direct is true and a gateway for a server is not
defined explicitly.
but it didn't work yet... returned err
NoMethodError: undefined method `fetch' ...
