So I've been following the Samba4 HOWTO, which has gone reasonably well. The issue I'm having is I can't get BIND9 to restart when the samba configuration is included in /etc/bind/named.conf.local
:
include "/var/lib/samba/private/named.conf";
But when I try and restart Bind9 with sudo /etc/init.d/bind9 restart
I get the error in my logs:
Oct 18 20:25:00 xxxx kernel: [ 251.397899] type=1400 audit(1350588300.188:16):
apparmor="DENIED" operation="open" parent=1807 profile="/usr/sbin/named"
name="/var/lib/samba/private/named.conf" pid=1810 comm="named" requested_mask="r"
denied_mask="r" fsuid=105 ouid=0
I've got the following rules in /etc/apparmor.d/usr.sbin.named
(which I thought were a bit OTT but I've been debugging for hours now)
/var/lib/samba/ rw,
/var/lib/samba/* rw,
/var/lib/samba/private/ rw,
/var/lib/samba/private/* rw,
/var/lib/samba/private/dns/ rw,
/var/lib/samba/private/dns/* rw,
For completeness, the perms on the offending file are:
-rw-r--r-- 1 root root 384 Oct 17 11:39 named.conf
I tried putting apparmor into complain mode, disabling the named profile, and bind9 starts perfectly and Samba works. But as soon as I restart the box, it's broke again, and I'd prefer to understand whats going on then taking bits of the servers's security out to make stuff work.
~ sudo aa-complain /usr/sbin/named
Setting /usr/sbin/named to complain mode.
~ sudo /etc/init.d/bind9 restart
* Stopping domain name service... bind9
rndc: connect failed: 127.0.0.1#953: connection refused
...done.
* Starting domain name service... bind9
...done.
Any help appreciated.
