I have had a few instances recently when named has failed to re-open its
TCP listening socket after a restart. This is particularly likely if I
try to bounce it quickly with a command line like
# rndc stop; /etc/rc.d/rc.named start
The servers in question are recursive (apart from a few local
Hi Folks,
Can BIND work as a Global Load Balancer? Or I am keen to know about
constructing GTM kindaa stuff which can monitor the health of devices and
route away traffic from failed ones by putting lower TTL value? I believe
F5 3DNS does the same thing?
Why use rndc to stop then the init script to start? Is there no
/etc/rc.d/rc.named restart? On RHEL5 the init script has a restart option so
it will stop then start.
If a socket is open then it could take a finite amount of time for it to close
making it unavailable on the restart if you

BIND does a sort of round robin to load balance among the IPs for a specific host; however, it does not monitor any health or routes and doesn't have the same capabilities as a GTM to choose what IP to answer for a name.I've worked with F5 GTM to monitor and route traffic based on health, status,
I understand BIND by default can not work like GLB but wondering if there
are any patches available or any other Open source software community is
aware of who can perform such thing.

I have a zone file in a view and there seems to be a single entry in the
file that shows and nxdomain when queried.
I have confirmed the view is correct and other entries are resolvable. I
have also run named-checkconf which shows no errors. There are also no
errors in the logs.
Any ideas?

I've got bind 9.8.1-P1 setup as a DNSSEC validating name server.

A long time ago I used a perl script called lbnamed that acted as a DNS server
and would monitor hosts and change the returned results based on aliveness and
load.

Hello,
I have the allow-transfer{} section in the global options{} block.
But for a special zone, I want to include another IP to allow transfer
besides the global IPs.
Is there a also-allow-transfer option in BIND?
If not how to control this?
Thanks.
