- Retreiving files with the File Transfer Protocol
-
- More than half of the bytes that traverse the internet do so
- through FTP. FTP is roughly analogous to the files section on a BBS.
- In FTP, however, all the files are not in one place. They're on
- thousands of computers world-wide. Perhaps you've heard about a
- particular FTP site in a newsgroup, or from a friend, or perhaps you
- used the archie tool to look for a specific file, and were given a
- list of ftp sites where you could find it.
-
- When you select ftp, enter the site name (example:
- "wuarchive.wustl.edu", which is one of the biggest sites in the world).
- You'll then be on the remote system as an FTP user. FTP sites work
- on the principle of a directory structure, much like a DOS drive.
- Files are typically kept in the "pub" directory, and subdirectories
- thereof.
-
- Common ftp commands:
-
- ls - List files in the current directory
- cd - Change directory (eg: cd pub)
- mget - get multiple files (eg: mget foo1.zip foo2.zip foo3.zip)
- page - look at a file, one screen at a time (eg: page README).
- bye - close the ftp connection.
-
- Files that you transfer are placed in your home directory here
- on the Exec-PC Internet Gateway. You can then download them with the
- File Transfers option on the main menu. Don't forget to remove them
- from your directory afterwards, as you have only 2 megabytes of space.
-
- Other things to remember are that filenames are case sensitive
- (this applies to just about everything on the Internet and in Unix).
- Also, if you restrict your ftp access to off hours, you're much more
- likely to connect to otherwise busy sites, and transfers will be an
- order of magnitude faster.
-
- The FTP software here normally logs you into the remote system
- as an anonymous user automatically. However, you may need to do this
- yourself at some point. Note: if you run FTP from the command line,
- you can use "ncftp", which logs you in automatically. The normal
- "ftp" program doesn't log you in automatically. To log in
- anonymously, at the login prompt enter either "ftp" or "anonymous",
- then at the password, you can enter your login name with a '@'
- appended to the end, which will send your full Internet address to the
- remote system (which most ftp sites require).
