Witam,
jak mozna skonfigurować anonimowe konto ftp z utworzonym drzewem katalogów do którego anonimowiu uzytkownicy będą mogli zapisywać i usuwać zapisane pliki, ale nie będą mogli usunąć już stworzonych katalogów?
Jak ustawić prawa?

Chyba będziesz musiał użyć funkcjonalność ACL na systemie plików. Lub jakiegoś innego rozwiązania typu SELinux czy podobne.
p.s. Temat posta do pupy, niewiele mówi.

Odpowiedź jest prosta:
user: ftp
katalog
/home/ftp/
/home/ftp/x
/home/ftp/y
/home/ftp/z
na x, y, z dla ftp pelne prawa a na /home/ftp/ zabieram prawa zapisu.
katalogow x, y, z nie usunie a będzie mógł do nic pisać.
Nie wiem czy to jest poprawne ale działa.
