VOL #1 Issue 2
A Technical Guide
This is a publication to help get you (and keep you) up to date with current trends and software used on the Internet. In our last issue we discussed basic applications and several key issues as related to the Internet and common usage of things like browsers and other standard client software. Our current issue is about file transfer software. This publication will be E-mailed every other Wednesday to help you stay abreast the ever changing Web scape and perhaps to even help you better understand what goes into the constant updates and various navigational paradigms used on qru.com and our contingent sites.
How did this get here?
File Transfer Protocol is an agreed upon standard for transferring files to and from a server over the Internet. Originally, invented to simplify and standardize this procedure the premise behind it is rather simple; A direct connection between the client machine and server is established. This connection is not stateless like The Hyper Text Transfer Protocol (HTTP), but rather is constantly kept alive through Pinging the server, or the server drops a connection after an amount of time specified by its administration.
There are two types of FTP connection, secure and insecure. A secure connection as the name implies requires a logon and password. An insecure connection will use a user's E-mail address as the logon. Often you will be able to access an FTP server over the internet in this fashion if retrieving programs from a company or drivers from a manufacturer. You will know it is a an FTP server if the location url begins with FTP:// as opposed to the usual HTTP:// prefix.
What Do We Recommend?
Our focus in software review this week is on FTP software (which likely to surprise you little at this point). These applications are especially useful if you have your own web site or want to deliver a large file to a friend to be retrieved at their leisure as opposed to leaving it in their E-mail where it can cause a number of irreversible problems.
The following Software can be downloaded for installation by clicking the icons. It is best to place the downloaded file in it's own temporary directory where it can expand. (You may need WinZip). Then run the setup program.
FTP Explorer 1.0 Far less complicated than almost any other FTP Client out there, the FTP Explorer allows you to drag-and-drop to and from the server just like a Windows '95 Explorer. Simple, polite install, gives you many useful FTP servers to choose from to start with. This is one of the few FTP client that attempts to resume failed downloads. A must have for the basic FTP user on a Windows '95 machine!
Ws_FTP 4.12 Washington State File Transfer Protocol is by far one of the better FTP Clients out there. With easy to understand interface just about anyone can do basic file upload and download with a few mouse click. All you have to do is point to the directory you want to download to and/or upload from press the appropriate arrow, and you file is transferred. A double click will allow viewing of files both local and remote. Advanced UNIX features such as CHMODE are just a right click away. This is another FTP program that supports attempts to resume a dowmload. The "lite" edition of this software is free!
Serv-U 2.2 An FTP Server, this is one that we are trying out in the office- and we like it! With Serv-U you can offer FTP access off of a dynamic IP like the one most people get with their dial-up accounts. You can set user access levels individually or by group and run full logs. Serv-U has a 30 day trial and is only $25 to permanently register this simple and complete solution.
Why do I Want to Know This?
If you are with an Internet Service Provider that gives you disk space on their server, then FTP is what you need to have to get your files up and out where people can see them. As was previously mentioned the other benefit is to avoid "mail-bombs" which is either an extremely large file or a multitude of mailings. If, for instance, you have several images of something that you or your friends enjoy you can give them access to your Internet account via FTP. If you have a large program at home and need to get it to work but don't want to carry it on disk... Or if you scan an image at work and can't fit it onto a disk. The useful applications of this protocol are endless, really.
FTP might seem obscure, but it is actually an everyday Internet function. Neither obscure or esoteric, FTP can enhance your enjoyment of the Internet tremendously. You can benefit with free software, memorabilia, archives, documentation, and more! Of course, and as usual, the entire issue can usually be avoided completely. Definitely; usage depends on what you would like to get out of or put into the Internet community.

PERLs of Wisdom
When anyone on our LAN hits a URL from their browser, Beauty (our server) raises an internet connection via proxy gateway, as follows:
This enables all shared drives to be mapped to virtual folders in the HTTPD directory of the LAN server, enabling WAN or Wide Area Network access connections. The Common Gateway Interface enabled allowing Perl and Server Side Includes (or SSI) to be parsed locally before our ISP receives final posting, enabling testing without external resource usage.
