restart named; missing TCP socket

2012-12-12 Thread Tony Finch
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 zon

Just wondering if BIND can do GLB -Global Load Balancing Stuff?

2012-12-12 Thread Manish Rane
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? ___

2012-12-12 Thread Lightner, Jeff
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 ha

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, l

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.
