Step One: Create an FTP guest group, using the Groupadd command, or an FTP group that you can create with an FTP server.
#less/etc/group//See if there are any, if the FTP server installed the group exists;
Step Two: Add the FTP user to the FTP group;
The third step: Modify the/etc/ftpaccess file, add the definition of Guestgroup: guestgroup ftp;
Or use Guestuser to specify the FTP user name directly, such as:
#guestuser Ftpuser;
Step Fourth: copy the necessary files to this user's $HOME directory, mainly with LS. General LS to Lib support, you have to recompile LS, or the Lib directory copy past, or copy the FTP server with LS, such as the/home/ftp/under the Bin,etc,lib three directory copy to the user's root directory, and modify the permissions:
Chown Username.ftp *
Note: now Linux under the FTP without copying these files, at least Redhat6.1 is not required to copy, so you can omit the fourth step.
