Hi,   I understand that my system contacts AS112 server but not sure why my system is contacting AS112 ROOT servers   Can you tell me what i need to do at server level to stop this. I read the RFC but no where it clearly mentioned why this is happening.   I have already configured forwarders in

Thanks to Mark, Phil and the offlist reply I got, it all makes more sense now, and I have it working perfectly! :) Your time and efforts are greatly appreciated. I don't know how many times I looked at that Bv9ARM.ch10.html page without seeing the dnssec-dsfromkey link! That would have answered

Dear Chris,   Thanks for your quick response. But my concern is; why this query is actually started going to AS112 servers.   Is it because my DHCP servers do not maintain PTR record zone for all internal IP address?   I need to have a solution to stop this query at host level instead of adding

Create RFC 1918 reverse zones for whatever parts of this address space you're using. Newer versions of BIND will do this automatically for you -- the zones are created without content. What version of BIND are you using? Chris Buxton BlueCat Networks On 4/26/11, babu dheen wrote: > Dear Chris,

Babu - if that's the case, and if the DHCP servers are only configured to use your BIND servers for DNS resolution, then perhaps its an issue with Windows DHCP and not BIND (unless you have configured BIND to forward un-auth RFC1918 to AS112 servers). Chris. > -- Forwarded message --

I changed our tsig key and broke the world. Actually, the DNS's are happy. DHCP appears to be happy, but I am generating bad keys. I wrote a script as follows: #! /bin/sh /usr/local/sbin/dnssec-keygen -a hmac-md5 -b 512 -n HOST keyname It produced a beautiful-looking key that bind was happy with

You can safely take the spaces out of the key string. It's base64, so whitespace shouldn't be important, but apparently dhcpd cares. #!/bin/sh filebase=$(/usr/local/sbin/dnssec-keygen -a hmac-md5 -b 512 -n HOST keyname) awk '/^Key: /{print $2}' $filebase.private | sed 's/ //g' Chris Buxton BlueC
