It appears that a "$ttl n" directive in your zone master file, where n
is an integer (I've tried as low a 1), will permit you to control the
TTL on the A RRs.
Doesn't seem to work for me:
------ zone file -----------
$ttl 1
@ 1s IN SOA malvm9.viu.ca. Postmaster.viu.ca. (
2008070602 ; Serial
7200 ; refresh every 2 hours
3600 ; retry every hour
12096000 ; expire in twenty weeks
1s) ; maximum NXDOMAIN cache
IN NS malvm3.viu.ca.
IN NS malvm9.viu.ca.
@ IN A 142.25.103.73
@ IN A 142.25.103.71
I restart the server:
MALVM9> mu netcon domain restart
Connected to NETCONTROL server on "LOCALHOST"
< malvm9.mala.bc.ca Network Control V5.2(10) at Mon 14-Jul-2008 9:55PM-PDT
< Shutting Down Nameserver
< Nameserver Shut Down
< Starting Nameserver
< Nameserver Started, process id 34600CBD
And do a lookup:
MALVM9> mu nslook vmscluster.mala.bc.ca localhost /debug

TTL still says 5 minutes. What did I do wrong?
