Nos exemplos abaixo irei mostrar como utilizar os comandos getfacl e setfacl para controlar acls de permissões no Linux / Samba: admin@localhost ~]$ getfacl teste.txt # file: teste.txt # owner: admin # group: admin user::rw- group::rw- other::r-- Agora vamos atribuir poderes para o usuario sidon [admin@localhost ~]$ setfacl -m user:Sidon:rw teste.txt Vamos ver o que nos mostra getfacl: [admin@localhost ~]$ getfacl teste.txt # file: teste.txt # owner: admin # group: admin user::rw- user:Sidon:rw- group::rw- mask::rw- other::r-- Tirando a leitura de "other" [root@localhost admin]# setfacl -m o:--- teste.txt O lque mostra getfacl: [root@localhost admin]# getfacl teste.txt # file: teste.txt # owner: admin # group: admin user::rw- user:Sidon:rw- group::rw- mask::rw- other::--- Importante: Para funcionar samba, inclua no smb.conf: #acls map acl inherit = yes inherit acl = yes inherit permissions = yes
