At IU, how do I use parallel FTP to transfer data to or from the MDSS?

Parallel FTP

Most Kerberos-enabled FTP clients work with Indiana University's Massive Data Storage Service (MDSS), but pftp_client performs best. If it is not already installed on the system you're using, obtain the client from:

Install the client on your Unix workstation. To transfer files:

1. Run the kinit command to authenticate to HPSS. Use the syntax shown below (with your IU Network ID username in place of username): kinit username@ADS.IU.EDU
2. Enter: pftp_client ftp.mdss.iu.edu
3. Enter: site setcos n

   Replace  n  with  1  for small files (0-4MB),  2  for medium files (4-64MB), and  3  for large files (64MB-1TB).

4. Enter: lcd directoryname

   Replace directoryname with the name of the directory containing your files.

5. For each file you want to transfer into MDSS, enter the following, replacing filename with the name of the file: pput filename

   If you use put instead of pput, usually pftp_client will automatically use pput instead.

6. For each file you want to transfer out of MDSS, enter the following, replacing filename with the name of the file: pget filename

   If you use get instead of pget, usually pftp_client will automatically use pget instead.

7. When you're finished, enter: quit
