Configuration of bind8

[Evans, Lorne R ISTA:EX]

	Hello:

	After successfully running W2K DDNS as master - I setup BIND
8.2.2.5P to be the master instead for the W2K zones.  I blindly specified
the W2K defaults for the SOA  as per the attached - but get the following
BIND messages.  Given the default TTL for the dynamic W2K SRV records
appears to be 10 minutes - are there any rules of thumb for determining
optimal BIND SOA values for the expire, retry, and refresh values?  I found
Jim's recommedation for expire - but - came up empty for retry and refresh?

	Thanks - and - attached....

master zone "_sites.blah.ca" (IN) loaded (serial 2000030615)
db._tcp.blah.ca: WARNING SOA expire value is less than 7 days (86400)
db._tcp.blah.ca: WARNING SOA refresh value is less than 2 * retry (900 < 600
*
 2)

The following is an example of a Microsoft DNS server generated default SOA
resource record: 


@   IN  SOA     nameserver.place.dom.  postmaster.place.dom. (
                               1            ; serial number
                               3600         ; refresh   [1h]
                               600          ; retry     [10m]
                               86400        ; expire    [1d]
                               3600 )       ; min TTL   [1h]

The expire time in the zone's SOA record is far too low. It should be
at least 1 week: a month is even better. This error is just a warning,
it's not a showstopper.

    Mickey> Feb 25 22:44:09 ApiS named[3262]: 2millcom.zone:10: IP Address
error (2mill.com.)  

Line 10 of the zone file 2millcom.zone contains a mangled IP
address. Think of it as a syntax error in the zone file. This error
prevents the zone from being loaded successfully, as was confirmed by
the log entry below.
