Okay, bare in mind the things mentioned elsewhere in the thread about
trying another sub-directory inside var/named for your dynamic records.
But what you've got now is probably important. The "defaults" sometimes
end up being different on different boxes. Perhaps due to whether users
just install BIND itself, or the local caching package?
ok .... /var/named/chroot/var/named is owned by root.named (default FC5)
.... i changeed (recursively) to named.named .... same message .jnl cant
be created.
the output from messages after a named and dhcpd restart and an
immeadiate lease request and ddns update is below.
Aug 1 17:28:51 server named[23130]: zone 'bac.org.au' allows updates by IP address, which is insecure
Aug 1 17:28:51 server named[23130]: zone '10.168.192.in-addr.arpa' allows updates by IP address, which is insecure
As I've commented on below, I found allowing updates by IP address
hasn't worked for some time. I don't know if it works again in FC5.
changed control clause to be updated by localhost and server (my server

As you can see ... everything seems to work ok except being able to
write the jnl file.
Not sure if the "timed out" error is the same thing, or related. I've
gone through the same myself, but resolved it too long ago. Not sure if
the denials are file writing denials, or configuration of name server
allowances.
the timeout error is a mystery to me ... its a DSL linux box asking for
a new lease (stopping NIC and restarting NIC)
If the chrooted /var/named... (/var/named/chroot/var/named...) it's
trying to access now doesn't have the right permissions, it won't be
able to write those files. What are the current permissions?
as above .... Fedora guys set /var/named/chroot/var/named owned by root
... changed it to named ownership .. no joy..same message re .jnl
named.conf -
//
// named.conf for Red Hat caching-nameserver
//
acl "bac-net" { 192.168.10.0/24; 127.0.0.1; };
options {
directory "/var/named/";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
listen-on { "bac-net"; };
allow-query { "bac-net"; };
Hmm, never seen the listen-on and allow-query statements refer to the
ACL before. Not sure if it's allowed, but my man file says it's port
and IP data inside listen-on. It does say that the allow-query is an
address match element, though.
the listen-on clause i use is straight from the DNS macro howto on ISC
website ... i thought it was odd too....but in retrospect, it means to
listen on 127.0.0.1 and any other NICS using 192.168.10.0/24 netowrk
that may be in the box ... naturally there is only the one NIC on that
network...it seems to work. ... i didnt change this though ... the point
is ... named is listening and responsding.
I would have thought allow-wuery would have been ok with an acl ... its
allowing every NIC on that acl.
//
// bac zone
//
zone "bac.org.au" {
type master;
file "/var/named/bac.org.au.hosts";
allow-update {
127.0.0.1;
192.168.10.254;
key rndckey;
};
};
I found that using addresses in the allow-update statement hadn't worked
for me since about Red Hat 8.0 Linux. I had to use an ACL name in
there, and that's all I've used. Seeing as you've set up one, acl
"bac-net", it seems rather redundant to then not use it and go about
manually specifying the addresses in all the places you could have just
put "bac-net", if you're also including addresses.
done .... removed IP addreses ... as per your named.conf further on
....... no change in message
Not that it should make any difference, you can omit that full file
path. You've set it, above, with the directory statement.
For subdirectories, you can just prepend the subdirectory name.
i.e. slaves/example.com.zone
Mine would have been done just as:
zone "bac.org.au" {
type master;
file "bac.org.au.hosts";
allow-update { key rndckey;};
};
agreed ... wasteful ... changed it but didnt expect any joy .... sure
enough ... no joy
dhcpd.conf --
include "/etc/rndc.key";
Are you using the same /etc/rndc.key between DNS and DHCP servers?
It'll need to be. That can be a /gotcha/ in chrooted servers.
yes same key file
subnet 192.168.10.0 netmask 255.255.255.0 {
ddns-domainname "bac.org.au";
ddns-rev-domainname "in-addr.arpa.";
authoritative;
ddns-updates on;
Not sure if the above two statements (authoritative & ddns-updates on)
had to be done outside of the subnet clauses.
a subnet specific clause ? ... one may have several subnets and only
want ddns-updates from slected subnets ... i think it can be used
globally or per subnet ... once again this is from the macro howto on ISC.
host admin {
hardware ethernet 00:0D:61:B4:AA:85;
fixed-address 192.168.10.1;
}
Fixed addresses won't get updated in the DNS records, you'd have to set
them in them manually.
I dont expect these to update .... i am testing with dhcpd assigned IP's
from the pool of the subnet. These addresses are already in the zone files.
so there u go .... i am not a linux expert, but also not totally inept
... i have a good working knowledge in general and I did think i could
try and get this going ... but the failure to create .jnl files persist ...
i am at a loss ... i cant think of anything else .... the salient point
seems to be that named cant write the .jnl file ... yet the directory
(now that I have changed it) belongs to it ... and still it wont write ...
Just in case I am going to check out the SElinux stuff ... i am fairly
certain that SElinux is disabled, but I need to make absolutely certain
... there seems to be few other clues ... stay tuned
