On Big Red, how do I transfer files using Grid-FTP (globus-url-copy)?

Note: Indiana University will retire Big Red from the TeraGrid July 31, 2011. After that date, TeraGrid accounts will no longer be able to submit jobs, all TeraGrid allocations on Big Red will be invalid, and access to Big Red via the TeraGrid User Portal will be disabled. Access via SSH keys or GSI-SSH for TeraGrid users will remain enabled for another three months. All data stored in TeraGrid accounts on Big Red should be backed up prior to October 31, 2011.

Acquiring a proxy

You must first acquire a Globus certificate. If you cannot, you can get a proxy using either the myproxy-logon command (use the NCSA default Kerberos password you received when you got your TeraGrid account) or the grid-proxy-init command (use the default NCSA Globus certificate passphrase).

To see if your proxy is still valid, enter:

The output should look something like this:

If timeleft is greater than zero, your proxy is still valid.

Transferring files from Big Red

The following example illustrates how to transfer files from Big Red to another cluster:

Replace bar with the name of the file you want to transfer.

GridFTP server names to use

For a list of all GridFTP server names and ports, see GridFTP/RFT Server Deployment by Site.

For more on GridFTP (including how to use globus-url-copy with more options) and other file transfer options on the TeraGrid, refer to Data: How to Initiate Transfers.

UberFTP is a command-line application that allows you to use traditional FTP commands against GridFTP servers and grid credentials. For help, see the UberFTP User Documentation.
