How to connect remote server using ProxyCommand?

+--------+       +----------+      +-----------+
| Laptop | <-->  | Jumphost | <--> | FooServer |
+--------+       +----------+      +-----------+

in your ~/.ssh/config, you will see the following.

Host Jumphost
  HostName Jumphost
  User ubuntu
  Port 22
