The SSH command offers a complete secured and encrypted connection between multiple hosts on the insecure network.  This SSH connection is also beneficial for file transfer, terminal access, and for different tunneling applications. Now let’s have a little information about Winbox; it is a small utility that provides Mikrotik RouterOS administration by a simple GUI(graphical user interface). In simple words, Winbox works as a native Win32 binary, but it can be run on different OS like Linux and Mac OSX by Wine.  Suppose that you use Mikrotik and wish to connect via SSH to another Linux...

In order to reach maximum productivity, you want to have the time on all the machines in your network synced.
