Back to step one
what is the command you use to SSH into the Amazon server?
Since scp is based on the ssh protocol, the scp command should look very
similar to your ssh command, just with the addition of a file that you want to copy and where you want to copy it, and possibly with a renamed flag or two.
For example, if you use
ssh -p 43533 user@host
to ssh into a machine, you would use
ssh -P 43533 user@host:/path/to/file .
to scp a file from that machine to your pwd.
Your ssh command will give you 99% of the syntax you need for scp.
