为什么 samba 无法授予某些目录的访问权限？

我有一台安装了 samba 的服务器。我需要共享 /var/spool 路径下的一些目录。但我遇到了奇怪的麻烦：我无法使用 samba 访问 /var/spool。

有 /etc/smb.conf （我出于测试目的共享了“/”。我之前有“/var/spool/asterisk/monitor”）：

############SMB.CONF##############
[global]
workgroup = DOMAIN
server string = DPM
netbios name = DPM
netbios aliases = fileserver
security = user
username map = /etc/samba/smbusers
encrypt passwords = yes
map to guest = bad user
hosts allow = 192.168.1.10
load printers = no
disable spoolss = yes
local master = no
unix charset = utf-8
dos charset = cp866
unix extensions = No
wide links = Yes
follow symlinks = Yes

[recordings]
  path = /
  writeable = no
  guest ok = yes
  browseable = yes

我有访问/var和/home/asterisk_recordings访问 samba 共享。

但是我没有访问/asterisk_recordings和/var/spool

这是他们的stat输出：

可能有什么问题？

答案1

嗯，SELinux 设置就是原因。

setsebool -P samba_export_all_ro 1解决了我的问题。
