File transfer

The three basic Internet appHcations of remote login, electronic mad, and file transfer are also budding blocks of more sophisticated appHcations that offer increased functionaUty and ease of network use. Tools such as Gopher, Wide Area Information Servers (WAIS), and World Wide Web (WWW) go beyond the three basic Internet functions to make information on the network easier to locate and use. Detaded descriptions of these tools are avadable (10). This trend toward more powerful, user-friendly networked information resource access systems should continue as Internet grows and matures. 

File transfer protocol (FTP) technology is a data communication tool that allows sending, accessing, and sharing files quickly and easily through a secure environment. The user logs onto the FTP site with a valid account name and a valid password. This method allows participants to share data files instantly. 

Data interchange - accepting and returning data via various file transfer mechanisms. 

File Transfer Protocol. A protocol used to move files over the Internet. Typically, you use a command line command, browser capability, or program on your computer called an FTP client to connect to an FTP server found on the Internet. Once connected to the FTP server, you can move files back and forth between your computer and the FTP server. SFTP, Secure FTP, is a more secure protocol for moving data over the Internet in which both your login information and data are encrypted during communications. 

There are many possibilities for the implementation of interfaces. They include file transfer, the use of transactions and the modern technology to define an integration layer and adapters (e.g., SAP NetWeaver). 

Connector Any means of communication between components we call a connector. A connector can be something as simple as a function call or a group of calls that provide for a collaboration, or it can be something more complex such as a dialog across an API. Or it might be a message sent via CORBA or COM or a file transfer, a pipe, or even the delivery of a deck of punched cards by courier. And of course, a GUI is a connector, just as a user is a component.

Various protocols are available for importing data from a remote computer to your PC. The simplest and most elegant way to perform this task is to use cither NFS (Network File Server) or FTP (File Transfer Protocol). An example of how NFS and FTP may be used within a local network, including the conversion of the corresponding data format into the WINNMR format, is outlined in section 2.7.2. 

The most convenient way is to use the NFS protocol, which has the effect of the hard disk of the central file server appearing as a normal PC disk (NFS mounted disk). NFS requires an Ethernet adapter and the NFS software, not included with the WINNMR software, to be installed on your PC. File transfer and copy operations of files stored on a NFS mounted disk are accomplished in exactly the same manner, using the same WINDOWS file manager or WIN-NMR commands, as for files stored on the hard disk(s) of your PC. 

GETFILE is started with the File Transfer command in both ID WIN-NMR and 2D WIN-NMR. For a transfer using FTP - the most common transfer protocol - the local and remote FTP must first be set up using the items in the FTP pull-down menu. After defining the file to be copied, a number of additional parameters must be set such as the type of data, the format (UXNMR/XWINNMR or WIN-NMR) to be used for the stored data and the destination directory. When all the appropriate parameters have been set, the transfer is initialised with the Get NMR-Files. .. command. 

A second alternative, available for both ID WIN-NMR and 2D WIN-NMR, is similar to the Filecopy Convert method just discussed. From the File pull-down menu choose the File Transfer option to load the GETFILE program. From the File pull-down menu in the GETFILE dialog box choose the Copy Convert UNIX-Files. .. option to transfer and automatically convert the selected file into the specified destination directory. 

For ID data files three possibilities using the Open, Filecopy Convert or File Transfer ID WIN-NMR commands are available and the procedures are the same as described above for UNIX format NMR data files. 

Activate File Transfer and Filecopy Convert and inspect their dialog boxes. These two options have been discussed in detail in chapter 2. If necessary, use the Help routine to get more information about using these options.
