ssh, sftp, scp usage notes

This gives basic examples of ssh use from the command line (also known as the terminal, cmd)  on Linux, MacOS, and Windows 10 machines. For serious ssh use on Windows we recommend installing MobaXterm instead.

ssh

ssh ID@computer.domain
e.g. ssh mr349@citadel.ch.cam.ac.uk

man ssh

scp

To copy files from the computer you are sitting at (local1) to a remote computer (server1):

scp ./file ID@server1:/home/ID/file
e.g.
mr@chm:~> scp womble.txt mr349@citadel.ch.cam.ac.uk:~
or:
mr@chm:~> scp womble.txt mr349@citadel.ch.cam.ac.uk:~/womble.txt

To copy files from a remote computer (server1) to the computer you are sitting at (local1):

scp ID@server1:/home/ID/file ./file
e.g.
mr@chm:~> scp mr349@citadel.ch.cam.ac.uk:~/womble.txt .
or:
mr@chm:~> scp mr349@citadel.ch.cam.ac.uk:~/womble.txt ./womble.txt

man scp

If you need to do scp from outside Chemistry's firewall to inside it, or vice versa, see https://www.ch.cam.ac.uk/computing/scp-over-ssh-tunnel

sftp

To sftp to a computer called server1.ch.cam.ac.uk

sftp ID@server1.ch.cam.ac.uk

> help
man sftp

X11 forwarding

ssh -X ID@computer.domain
e.g. ssh -X mr349@citadel.ch.cam.ac.uk

The -X is the option for X11 forwarding and if you are using a medium/slow connection then you might want compression: -C.
