For transferring data from Mac / Windows computers to MSI Unix computers, any SFTP or SCP software can be used. Connect to an MSI system using your MSI username and password and you will be able to transfer files to and from your home directory and group shared directory. For Windows, we recommend WinSCP. For Mac OS X, we recommend using FileZilla.

$ smbclient -U 'MSI\username' -D username //falcon2/Users

You can issue ftp style commands ('ls', 'get', 'cd', etc.). To get an entire directory recursively, use:
smb: \username\> prompt smb: \username\> recurse smb: \username\> mget DirectoryName
