BIND 9.4.3-P2 assertion failure

2011-03-29 Thread Oleksii Krykun
Hi,

I used BIND 9.4.3-P2 on FreeBSD 7.2-RELEASE (which is built-in) about two
years without problems.

Since last Friday sometimes I see  error messages like following:

Mar 28 16:44:06 gate2 named[60455]:
/usr/src/lib/bind/isc/../../../contrib/bind9/lib/isc/unix/socket.c:2361:
INSIST(!sock-pending_accept) failed

Mar 28 16:44:06 gate2 kernel: pid 60455 (named), uid 53: exited on signal 6

What is a reason of this problem? No any system configuration changes were
made last time.

I use BIND as caching DNS server for a my LAN. Squid server only queries
this BIND.

My named.conf is:

Subject: GUI for bind

Hello,

I'm looking for a GUI for bind that meets the following requirements:

(1) Must still be under development (and supported, either commercially or 
via community support)
(2) Supports accounts/groups that will allow me to create user accounts 
that are able to modify only zone records assigned to the account/group.
(3) Administrator access with the permissions to modify any zone record.
(4) Should support most common features of bind.
(5) Should support 100's of zone records.
(6) Should be somewhat easy to use, so that non-experts can figure it out.

The product does not have to be free... a commercial product is perfectly fine.
I've spend some time searching around, but most of the GUI products either 
don't support bind or are no longer maintained...

Any recommendations would be appreciated...

Thanks

Note that fedora/rhel have a package bind-pkcs11 that *should* would without

dynamically updating the forwarders with bind/rndc

2011-03-29 Thread Paul Wouters


Hi,

Is there a way for bind9 (or planned for bind10) to dynamically update the 
forwarders via
rndc? I believe currently the only way to do this is to rewrite the config file 
and then
cal rndc reload.

This is not something that lends itself to automating based on a network 
manager based
network that receives DHCP updates and needs to reconfigure the forwarder based 
on the
obtained DNS server options.

I know unbound can do this using unbound-remote forward a.b.c.d.

If a patch for bind9 would be written to allow this via rndc, would it have a 
chance of
being accepted?

I believe there's a DBUS interface that NetworkManager on Linux uses for

the DBus interface is old and is not compatible with current

I apologize for the cut off reply. I accidently hit send before I was
complete.

If by some domains have 12 ips you mean a 12 A record round robin, then it
is important remember that BIND doesn't have any way of telling the load on
the 12 servers. So it's load sharing not load balancing.
The f5  is load balancing so you would see a more even load across the 12
servers.

If you use round-robin DNS you are relying on the clients not to muck
around with the responses they get from your DNS server. If they sort
them, for example, that will mess up the balancing. For example RFC 3484
screws it up.

TTLs and Timeout Question

2011-03-29 Thread listmail
I'm investigating the failure of a slave server during a network outage at a
primary server.

The slave server was running and answering queries, but not delivering results
for domains for which it is authoritative during the outage. Since the outage
occurred in the middle of the night, I have no tests during the outage period
and have to infer from logs and the behavior of everything that depended on
this server.

The SOA TTL was 1 week on most zones, but the individual records had short
TTLs, on the order of an hour. The outage lasted long enough for these shorter
TTLs to expire.

My question is: Will a BIND slave server stop serving RRs when their
individual TTLs have expired, or only when the SOA TTL has expired?

Bill,

You are getting issues confused. TTL is the time for a server to cache
data for which it is not authoritative. For an authoritative server TTL
is irrelevant. Also, the TTL in the SOA is the TTL for negative cache
entries, not cached data. (And, if the server is authoritative, it is
NOT cached data.)

The relevant field in the SOA is the expire' field. If the server has
either transferred the zone from the master server or confirmed (via
serial #) that the current data is still current. If the data is
expired, the slave will stop serving it. Until then, it will serve it
and TTL has absolutely nothing to do with this.

I should note that you really need to have rational values for refresh,
retry, and expire in your SOA. I like a refresh on the order of an hour
for stable zones and 15-30 minutes for fast changing ones. I set retry
to about 15 minutes and expire to a couple of weeks.

Finally, you probably want your minimum TTL set to a fairly short time
like 15 minutes so that you will not continue to use a negative cache
entry for too long. It is fairly common for a new name to be queried
before it gets into DNS. It may get updated in just a few seconds, but
the server will continue to respond that it does not exist until the
negative cache TTL expires.

I guess I didn't state my question very well. When I referred to the SOA TTL,
I was referring to the expire field, not the negative cache timeout field.

 expired, the slave will stop serving it. Until then, it will serve it
 and TTL has absolutely nothing to do with this.
 

So is this correct: A slave will continue serving RRs regardless of their TTL,
as long as the expire value in the SOA has not expired?

If true, I need another theory as to why the slave stopped serving records.

children whose zones do not reflect the delegation from the parent

2011-03-29 Thread ben thielsen
hi-

i'm curious for some feedback on something i've noticed here and there, and 
came across again the other day.  my experience with dns, and the method which 
i've always practiced, is that when a zone is delegated, there should be 
agreement between the parent and the child - that is to say that whatever 
nameservers the parent lists for the zone, all children should also list.

i've noticed though, from time to time [it seems to be most common in 
in-addr.arpa. zones], i see a case where a parent has delegated a zone, but the 
child does not corroborate this delegation.

an example is 33.50.in-addr.arpa.  according to the parent, there are two 
nameservers responsible for this zone:

dig @dill.arin.net 33.50.in-addr.arpa ns +norec

when asking these two servers the same question, i expected them to provide the 
same answer [but in the answer section, of course] - but:

both fail to do so.  so - it would seem to me that at least somehow, in some 
sense, the delegation is broken.  however, if queried further for a /24 within 
that /16, both servers now work properly, and further delegate to other
