ftpd_selinux(8) ftpd SELinux policy documentation ftpd_selinux(8)
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 pub- lic_content_t file type to the directory and by restoring the file type.
semanage fcontext -a -t public_content_t "/var/ftp(/.*)?"
restorecon -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 -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.

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

setsebool -P allow_ftpd_full_access on

setsebool -P allow_ftpd_use_cifs on
