Configuring File Transfer Protocol (FTP) servers

Configuring user classes

A user class defines a set of users according to the account type they are accessing and their IP address or domain name. You can then limit access by classes as described in ``Setting class limits''.

NOTE: The special class anon is predefined for anonymous FTP users accessing the FTP server from any IP address. If you remove this class, an anonymous user will not be able to log into the FTP server unless the anonymous user is defined as a member of another class whose address matches that of their system.

To configure a class using the FTP Server Manager:

Select View Classes.
To define a new class, select Edit Add.
To modify an existing class, click on the group from those displayed, then select Edit Modify.
Enter the following information for the class:

Class name
A unique name for the class.
User types
The types of user who will be included in this class. Select one or more of:

Anon
corresponds to ftp or anonymous
Guest
members of a guest group
Real
real users defined on the system

Addresses
One or more IP addresses or domain names which define where you expect users in this class to be coming from. You can use the character ``'' to replace any element of an address. For example, ``'' would match all addresses, ``.mynet.com'' would match both rivers.mynet.com and seas.mynet.com, and ``200.25..'' would match any IP address that begins 200.25.
For each address you enter, click on Add to add it to the list.
Anon group
The name of the group to which an anonymous user in this class will be set. This allows you to set up directories and files that only certain classes of anonymous users can access.
Click on OK to accept.
