Configure anonymous File Transfer Protocol

Anonymous File Transfer Protocol (FTP) enables remote users to use the FTP server without an assigned user ID and password.

Anonymous FTP enables unprotected access (no password required) to selected information about a remote system. The remote site determines what information is made available for general access. Such information is considered to be publicly accessible and can be read by anyone. It is the responsibility of the person who owns the information and the system to assure that only appropriate information is made available.

To access this information, a user logs on to the hosts using the user ID ANONYMOUS. The user ANONYMOUS has limited access rights to the files on the server and has some operating restrictions. Typically, the following operations are only operations allowed.

• Logging on using FTP
• Listing the contents of a limited set of directories
• Retrieving files from these directories.

Typically, anonymous users are not allowed to transfer files to the FTP server system. Some systems do provide an incoming directory for anonymous uses to send data to. Traditionally, the special anonymous user account accepts a string as a password, although it is common to use either the password 'guest' or one's e-mail address. Some archive sites explicitly ask for the user's e-mail address and do not allow logon with the guest password. Providing an e-mail address is a courtesy that allows the archive site operators to get some idea of who is using their services.

1. Prepare for anonymous File Transfer Protocol
   You might need to know how to set up your anonymous File Transfer Protocol (FTP) and ensure the security of your FTP.
2. Write exit programs for anonymous File Transfer Protocol
   To use anonymous File Transfer Protocol (FTP), you need to write two exit programs: FTP Server Logon exit program and FTP Server Request Validation exit program.
3. Create an i5/OS user profile: ANONYMOUS
   To prevent anyone from directly signing on to the iSeries server with the user profile ANONYMOUS, you need to create a user profile of ANONYMOUS and assign it a password of *NONE.
4. Create a public library or directory
   After creating anonymous users, you might want to create a public library or directory for them to use. Typically anonymous users should only be able to access public files.
5. Install and register exit programs
   You can create a library to contain your exit programs and their log files, compile the programs, and register them for use by the File Transfer Protocol (FTP) server.
