File Transfer To Clusters

A single, central file server, storage01.cac.cornell.edu, serves all CAC user home directories. You can connect to this server in a variety of ways from any operating system to access your files.

Secure Copy

Secure copy is a standard tool to copy files to and from remote hosts.

localhost$ scp localfile.dat username@linuxlogin3.cac.cornell.edu:remoteinput.dat
