Hey List,
Not sure why this is happening so perhaps someone can explain this
to me.
Whenever I update bind it messes up/resets access rights on my
zone
files. Now normally this wouldn't be a bad thing, but because
I have
dynamic updates on, for which named creates journalizing files, I
end up having non-writeable journalizing files. So after every
update I end up having to manually change the access rights on my
jnl files.
Is anyone else having the same problem and/or is it supposed to be
like this?
You must have bind configured to run in chroot.
rpm's %post script runs /usr/sbin/bind-chroot-admin where, if you
have chroot configured, it runs this lovely bit of code:
chown -h root:named /var/named/* >/dev/null 2>&1;
chown -h root:named ${BIND_CHROOT_PREFIX}/var/named/* >/dev/null
2>&1;
chown -h root:named /etc/{named,rndc}.* >/dev/null 2>&1;
chown -h root:named ${BIND_CHROOT_PREFIX}/etc/{named,rndc}.*
/dev/null 2>&1;
chown -h named:named /var/log/named.log >/dev/null 2>&1;
chown -h named:named ${BIND_CHROOT_PREFIX}/var/log/named.log
/dev/null 2>&1;
chmod 750 ${pfx}/var/named >/dev/null 2>&1;
chmod 640 ${pfx}/var/named/* >/dev/null 2>&1;
chmod 750 ${pfx}/var/named/*/. >/dev/null 2>&1;
chmod 660 ${pfx}/var/log/named.log >/dev/null 2>&1;
chown -h named:named
/var/named/{data{,/*},slaves{,/*},dynamic{,/*}} >/dev/null
2>&1;
chown -h named:named
${BIND_CHROOT_PREFIX}/var/named/{data{,/*},slaves{,/*},dynamic{,/*}}
/dev/null 2>&1;
chmod 770 ${pfx}/var/named/{data,slaves,dynamic} >/dev/null
2>&1;
chmod 660 ${pfx}/var/named/{data/*,slaves/*,dynamic/*}
/dev/null
2>&1;
chmod 770 ${pfx}/var/named/{data/*/.,slaves/*/.,dynamic/*/.}
/dev/null 2>&1;
Lovely.
Heh, that's indeed lovely. And yea, I've got named configured to
run
in chroot as it is the default nowadays (at least on Fedora).
You should note that the 'dynamic' subfolder contents are set to mode
660.
Move your updateable zone files there and update the referenced paths in
named.conf accordingly.

Could you clarify your statement for me please?
1. Othe than my zone files, what else goes into
/var/named/chroot/var/named/dynamic ?
2. My named.conf resides in /var/named/chroot/etc, so I need to make changes to
point to the path --> /var/named/chroot/var/named/dynamic ?
Thanks
I cannot really clarify point 1, but I can somewhat clarify point 2.
In my named.conf I now have the following:
zone "0.168.192.in-addr.arpa" IN {
type master;
file "dynamic/named.0.168.192";
allow-update { key rndc; };
};
zone "home" IN {
type master;
file "dynamic/home.zone";
allow-update { key rndc; };
};
This allows named to find the zone files inside the dynamic folder.
Also, /var/named/chroot/etc/named.conf has a hardlink to /etc/named.conf
so that might be somewhat easier to type next time you want to edit that
file :). And because named is running inside a chroot, you cannot set
the path to "/var/named/chroot/var/named/dynamic" inside the named.conf.
For named, the chroot basically means that everything is running from
the /var/named/chroot directory. In other words, if you refer to
/var/named/dynamic inside your named.conf, it actually refers to
/var/named/chroot/var/named/dynamic.
Hope this makes sense :)
