RE: BIND help

[George Bonser <grep@oriole.sbay.org>]

The file below is totally hosed.  How many systems do you have and how many IP
addresses do you have?  I see only one A record so assuming that you only have
one system on your net (but that reference to paul.3dillusion.com throws me)
You can START with something like this:

@             IN      SOA ns.3dillusion.com hostmaster.3dillusion.com (
                               97110701        ; serial yymmddxx
                               10800           ; refresh 3 hours
                               3600            ; retry 1 hour
                               3600000         ; expire 1000 hours
                               86400 )         ; minimum 24 hours
              IN      A               198.109.162.43
              IN      MX      100     mail.3dillusion.com.
              IN      HINFO   I386    LINUX
              IN      NS              3dillusion.com.
ftp           IN      CNAME           3dillusion.com.
mail          IN      CNAME           3dillusion.com.
www           IN      CNAME           3dillusion.com.
3dillusion    IN      CNAME           3dillusion.com.
paul          IN      CNAME           3dillusion.com. 

What this does is create ONE system (note only one A record) with a bunch of
aliases (CNAME) records pointing to it.  If you add another system (say
ftp.3dillusion.com) you REMOVE the CNAME record, ADD an A record like this:

ftp             IN      A               ???.???.???.???

Where you replace the ???.???.???.??? with the real IP address.

WHat your file below does is create a subdomain of ns and creates a bunch of
alises that point to systems that have no A records ... which means that they
don't exist!

Every name must have EITHER an A record that points to an IP address OR a CNAME
record that points to another name that has an A record.
