I often forget the syntax for getting files over a SSH connection.
scp user@address:/path/to/file /path/of/new/file
scp firstname.lastname@example.org:/tmp/mysql/test.sql .
Will transfer test.sql to the current folder (.) Also, if you need to change the port, just use the -P option
scp -P 9000 user@address:/path/to/file .
If you want to transfer a file TO another server:
scp /path/of/file user@address:/path/to/new/location
