NAME
       ftpd_selinux - Security-Enhanced Linux policy for ftp daemons.

DESCRIPTION
       Security-Enhanced Linux provides security for ftp daemons via flexible mandatory access control.

FILE_CONTEXTS
       SELinux  requires  files to have a file type. File types may be specified with semanage and are restored with restorecon.
       Policy governs the access that daemons have to files.

       Allow ftp servers to read the /var/ftp directory by adding the public_content_t file type to the directory and by restor-
       ing the file type.

       semanage fcontext -a -t public_content_t "/var/ftp(/.*)?"

       restorecon -F -R -v /var/ftp

       Allow  ftp  servers  to  read  and write /var/tmp/incoming by adding the public_content_rw_t type to the directory and by
       restoring the file type.  This also requires the allow_ftpd_anon_write boolean to be set.

       semanage fcontext -a -t public_content_rw_t "/var/ftp/incoming(/.*)?"

       restorecon -F -R -v /var/ftp/incoming


BOOLEANS
       SELinux policy is based on least privilege required and may also be customizable by setting a boolean with setsebool.

       Allow ftp servers to read and write files with the public_content_rw_t file type.

       setsebool -P allow_ftpd_anon_write on

       Allow ftp servers to read or write files in the user home directories.

       setsebool -P ftp_home_dir on

       Allow ftp servers to read or write all files on the system.

       setsebool -P allow_ftpd_full_access on

       Allow ftp servers to use cifs for public file transfer services.

       setsebool -P allow_ftpd_use_cifs on

       Allow ftp servers to use nfs for public file transfer services.

       setsebool -P allow_ftpd_use_nfs on

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
