At IU, how do I use SFTP or SCP to access my SDA account?
If you want to use a graphical client, UITS recommends downloading and installing one of the following free, open source clients:
- OS X: Cyberduck
- Linux: AnyClient
- Windows: WinSCP
To use WinSCP with your SDA account, disable Endurance in the WinSCP Preferences (select the options highlighted in the screenshot below, and then click ):
When you connect to your SDA account, the default directory is your
home directory. The path to your home directory depends on the first
two characters of your username (e.g.,
/hpss/d/a/darvader). However, most SFTP clients will
display your home directory with the class of service prepended (e.g.,
Files you create in your home directory are assigned a default
class of service (
/cos1). If your files are too large for
the default class of service, you can switch to another one. To do so,
change to another directory by replacing the
prefix; for example:
- To change to class of service 2, prepend
/cos2to your current directory (e.g.,
- To change to class of service 3, prepend
/cos3to your current directory (e.g.,
The contents of the directory will appear the same in either case, but writing files to the different directories creates files in the selected class of service. For more, see On the Scholarly Data Archive at IU, what are classes of service, and how do I use them?
If you frequently use different classes of service, you can create links in your home directory to make changing directories easier. For example, in SFTP, you can do the following (replace the example username, home directory, and filename with your own):
sftp email@example.com sftp> symlink /cos3/hpss/d/m/dartmaul big sftp> cd big sftp> put my_big_file.zip
Although you must use SFTP to create the link, you can use it with SCP; for example:
scp *.zip firstname.lastname@example.org:big
If you have questions about accessing your SDA data using SFTP or SCP, or need help, email the UITS Research Storage team. For information about other methods for accessing the SDA, see At IU, how do I access the SDA?
