А в чем проблема, если у Вас логие\пароль есть?
scp username@192.168.1.111:/path/to/myfile.txt /Users/Jamie/local/path/to/myfile.txt
scp copies files between hosts on a network. It uses ssh(1) for data
transfer, and uses the same authentication and provides the same security
as ssh(1). scp will ask for passwords or passphrases if they are needed
for authentication.
