Ubuntu Installation Salt-ssh

Introduced:

Salt-ssh is a new feature of 0.17.0, the name will know that it is dependent on SSH for remote command execution tools, the advantage is that you do not need to install Minion on the client, do not need to install master (directly installed SALT-SSH this package), a bit like Paramiko, PSSH, ansible such tools, sometimes you really need salt-ssh (for example: conditions do not allow the installation of Minion, not long-term management of a minion) the most important thing is salt-ssh is not just a simple SSH tool, it supports Salt most of the functions, such as grains, modules, state, etc.

Note that SALT-SSH does not inherit the original communication architecture (ZeroMQ), which means that it will be slower to execute.
