Pulling: Let’s say you have a terminal on your host open, you could do:
scp user@192.168.1.100:/tmp/myfile /tmp/files/myfileThis way you are creating a “second tunnel” towards your server.
Pushing: (The other way around) so from your server to your host (essentially it is now a tunnel in your original tunnel):
scp /tmp/myfile user@192.168.1.5:/tmp/files/myfile
