  • Does it chroot each user home dir? It is hard to exec after chroot command because all dynamic libs need to be in the chroot tree, but if the ftp server does chroot() call after login, when there is not more exec(), no problem, and the rest of the system disappears.
  • HTTP/1.1 even has compression (does it compress uploads?)!
  • Maybe a web page script that sends video files raw via a custom tcp/ip server.
  • Maybe build an email receiving script to store unique video files under a web server and forward other emails.

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 public_content_t file type to the directory and by restoring 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.
