File Transfers

How do I copy files to and from /work?

All file transfers to/from work to/from other sources like your laptop or LSS must be done through the machine:

prontodtn.las.iastate.edu

This diagram shows the larger capacity network connections on prontodtn, which explains why we require files to be transferred through prontodtn & not pronto:

You can use prontodtn.las.iastate.edu for scp from your desktop or another location and you can also access LSS, mounted at /lss, on prontodtn.

To use scp, you will first need to ssh to prontodtn.las.iastate.edu. You may be prompted for your password twice. You should enter it both times to ensure that you get a Kerberos ticket. If you are not prompted for it a second time, run

kinit

After entering your password, you can disconnect from ssh. scp should then work.

You can also access your files via SMB share. Enter \\prontodtn.las.iastate.edu into your explorer window if you're on Windows, or smb://prontodtn.las.iastate.edu in the finder connect dialog if you're on MacOS. You will need to be on campus or connected to the VPN.

Note: The ISU VPN has limited bandwidth. If you have a large amount of data to transfer, or you want to transfer files without using the VPN, we recommend that you use Globus.
