For Mac / Linux users, you can do so in the Terminal using the scp command
Login into our server, and go to the directory of your source file. Use
$ pwd
to show the current path.
Then, open another terminal, go to the directory you where you want your file to be saved, then do
$ scp [username]@{VMname}.lbl.gov:[source path]/[file name] .
You can copy and paste the [source path] and [file name], and you combine the use of wildcard character (* or ?) if you want to transfer multiple files at once.
Notice you will be asked your password every time you do scp
xftp offers a friendly user interface for you to transfer files between your local machine and the server. You can save your login information and then drag the files between both ends.
It works for both Mac and PC users.
I have all the useful output files for the hands on session saved in the
/home/[username]/ALSWorkshop/Outputs/
You can try to download a few of them to your local machine, and use Avogadro to play with them.
