File Transfers

Transfering files to and from the clusters.

 

Files can be moved both to and from the clusters in a variety of ways:

SCP

To copy a file from another linux or Mac machine into Condo, issue the following command on that machine:

  scp file condodtn.its.iastate.edu:  

This will copy the file into your home directory on Condo. condodtn is the data transfer node. Your home and group working directories are mounted on all nodes of the cluster, including condodtn.

Larger files should be kept in the group working directory (/work/<group>/<user>, where group is your group name, and user is your user name). On a remote machine issue

  scp file condodtn.its.iastate.edu:/work/<group>/<user>

to copy files directly to the group working directory. To find out your group, on Condo issue "groups" command.

It is also possible to ftp from Condo. This is faster than scp for large files because the file is not encrypted.

ssh is usually available on any Linux machine.

For Microsoft Windows based machines, ssh is available as part of Windows ITS downloads under the link for Secure Shell.

 

FileZilla

FileZilla can be used to transfer files in sftp mode.   None of clusters support standard ftp as that would send your username and password in the clear which is both a bad idea and agaisnt ISU policy.

This video demnstrates how to configure FileZilla for cluster transfers.
