SSH Client Nodes
SSH Client
This node has a disadvantage that it cannot display the executed command result in debug. The debug will only show Ssh client error and close.
But the ssh client node will show result at the bottom.

Interactive SSH
This cannot execute the command in ssh. The debug only shows login details from ssh.

A[inject] -->|"msg.payload [str] = ls"| B[interactive ssh];
B -->|login details| C[debug];
BigSSH
The bigssh node can execute ssh and other commands within ssh session, then print out login details and executed command results.

A[inject] --> B[BigSSH];

B -->|msg.control: success or not| E[2.debug:control]
B --> D[3.debug:stderr];
