Data Transfer to DaLI

RCC provides a number of methods for accessing and transferring data in/out of DaLi. We recommend the :command:scp protocol for transferring files to/from RCC systems. RCC hosts a managed Globus Online endpoint that can be used for moving very large amounts of data.

SCP

Secure copy or SCP is a means of securely transferring computer files between a local host and a remote host. It is based on the Secure Shell (SSH) and Secure File Transfer (SFTP) protocols.

Command-Line Operation

Most UNIX-like operating systems (Mac OS X, Linux, etc) provide a:command:scp command which can be accessed from the command line. To transfer files from your local computer to your home directory on DaLI, open a terminal window and issue the command::

Single files: $ scp <some file> <CNetID>@dali-login.rcc.uchicago.edu:
Directories:  $ scp -r <some dir> <CNetID>@dali-login.rcc.uchicago.edu:

When prompted, enter your CNet password.

WinSCP GUI for Windows Clients

WinSCP is a scp client software that can be used to move files to and from DaLI and a Windows machine. WinSCP can be obtained from http://www.winscp.net.

When setting up your connection to DaLI in WinSCP, use the following information::

Hostname: dali-login.rcc.uchicago.edu
Port:     22
Username: CNetID
Password: CNet password

After connecting, if you are prompted to accept the server's host key, select "yes."

Upon successfully connecting, the main WinSCP window allows you to move files from your local machine (left side) to DaLI (right side).

Globus Online

Globus Online is a robust tool for transferring large data files to/from DaLI. The RCC has a customized Globus Online login site at https://globus.rcc.uchicago.edu and uses Single Sign On capabilities of CILogon. If you have already signed up, here is the connection information::

URL:       https://globus.rcc.uchicago.edu

Follow these instructions to get started:

  • Go to https://globus.rcc.uchicago.edu and hit Proceed

  • Select "University of Chicago" for the Identity Provider

  • If you want to transfer files from your local computer, click the More Options link on the File Manager page and follow the instructions in Install Globus Connect Personal.
