It basically allows you to enter an SSH user name and password on the command line, so you can create a connection without any interaction. A far better way to accomplish that is with public/private keypairs. But it's still something I find useful from time to time, and I'd rather mention it with all the warnings in the world than to pretend it doesn't exist.

send files via
scp to hundreds of machines in my local network that

a lifesaver if you need it. Search your distribution's repositories,
as it's available for most systems. And remember, don't ever use it!
