Access level (ANONYMOUSLEVEL)
Use the access level to set the type of access permitted for
anonymous users.
There are three levels of access for anonymous support.
(Level 2 was provided for migration purposes only and not supported by msys.)
IBM recommends using level 1 or 3.
"Place restrictions on anonymous users?" options:
- "No (ANONYMOUSLEVEL=1)"
This is the default, and is equivalent to anonymous
login support provided by releases prior to OS/390 V2R10. If you select
ANONYMOU for the user ID under login processing then the anonymous user
needs no password and has unrestricted access to the MVS and HFS file systems.
If you enter a user ID under login processing, then the anonymous user's access
is based on the access of the user ID specified.
- "Yes (ANONYMOUSLEVEL=3)"
Allows you to further
restrict the access of anonymous users to the system's resources. The following
restrictions can be customized.
- The file systems the anonymous user can access.
- The permission bits for creating HFS files and directories.
- The method of operation (SEQ,JES,SQL) of the server that is allowed.
To set these restrictions, click the "Restrictions..." button.
Additional functions of level 3 include:
- Anonymous users cannot issue the USER command to leave anonymous mode.
- Named users cannot issue the USER command to enter an anonymous login.
- Users can login using a SURROGATE password.
Anonymous HFS directory structure
With restricted access, if the start directory is HFS, the
FTP server uses the chroot command to set the anonymous user's root directory. If
the start directory is MVS, no chroot is created and the user has
unrestricted access to the HFS file system. When the start directory is HFS, you
must create a specific directory structure and contents within the anonymous user's
home directory. This directory structure is needed so the FTP client maintains
addressability to needed executables once the chroot is executed. For details about
creating the required directory structure, use the following link:
