Moving data

There are in principle three ways to transmit data: the hyperchannel link (VAX tex2html_wrap_inline1523 IBM only), standard FTP and, for binary data only, the GSI-made bincopy utility. A fourth one, the CERN utility ZFTP, is not fully functional on all computers.

On UNIX systems you can automate the FTP "login" sequence if you transfer data exclusively between the same two nodes/accounts using a file .netrc in your home directory. Insert the line(s):

machine <remotenode> login <uid> password <password>
The .netrc must be protected against everybody else but you:
chmod o-rw        # disable others
chmod g-rw        # disable group

Please note that the file/dataset naming conventions are different on the different computers, in particular, special characters like _, $, #, @ cause nothing but trouble, so avoid them wherever possible (see gif).
