Zones - NAT'ing
Hi gurus.

Not such a problem, more of a proof of concept.

Ive got two zones :- database-1 and database-dr-1 on two different servers. Both zones have different ip addresses.

I want to copy the whole zone database-1 over to database-dr-1, which is simple enough, but I want to install some sort of NAT / Ip fitler on the dr zone, that converts the zones ip, into the ip of the copied over zone. Possible ??

If this is possible, I can then not bother with updating the applications once copied over, just have an extra network layer which converts the copied over IP / host details, into the dr zone.

Any ideas ?

Both physical servers are connect to a san, which will soon sync up with each other. This means if I install the zone / apps on SAN storage, on the event of a failed site, I could mount the storage / zone on the DR server and fire it up. Hence the question about being able to NAT etc etc.


Basically, Im uses zones, and am trying to think of ideas about DR. So, any ideas of zones and DR would be great full.

zonec

zonec(8)                                                            nsd 3.2.12                                                            zonec(8)

NAME

       zonec - NSD zone compiler version 3.2.12.

SYNOPSIS

       zonec [-v] [-h] [-C] [-L] [-F] [-c configfile] [-d directory] [-o origin] [-z zonefile] [-f database]

DESCRIPTION

       Zonec  is  the  nsd(8)  database  compiler for creating name space databases from a set of input master zone files specified in nsd.conf(5)
       file.

       It is normally invoked via nsdc(8) rebuild command.  Zonec will then parse every zone in nsd.conf(5) file and add  it  to  the  name  space
       database, /var/lib/nsd3/nsd.db by default, that is used by nsd(8) to answer incoming queries.

OPTIONS

       -c configfile
              Read specified configfile instead of the default /etc/nsd3/nsd.conf.

       -C     No config file is read (use with -f, -o and -z).

       -d directory
              Change the working directory to directory before doing any work. Overrides zonesdir: option in config file.

       -f database
              Create the specified database instead of the file specified as database: in the config file.

       -o origin
              Use  this  as  the  first origin. Zone information is read from zonefile specified with -z. When reading zones from config file this
              option is ignored.

       -z zonefile
              Reads all zone information from zonefile.  If zonefile equals `-`, then all zone information is read from stdin,  making  constructs
              like:

              # cat zones* | ./zonec -C -f nsd.db -o example.net -z -

              possible. When reading zones from config file this option is ignored.

       -v     Increase  the  verbosity  of zonec. This flag can be specified multiple times to increase the level of verbosity. The first level of
              verbosity will print per zone summary information. The second level of will print progress information  for  each  10,000  RRs  pro-
              cessed.

       -F     Set debug facilities. (If compiled with --enable-checking.)

       -L     Set debug level. (If compiled with --enable-checking.)

FILES

       /var/lib/nsd3/nsd.db
              default NSD database

       /etc/nsd3/nsd.conf
              default NSD configuration file

DIAGNOSTICS

       Zonec will log all the problems via the standard error output and progress via stdout if the v option is specified.

SEE ALSO

       nsd(8), nsdc(8), nsd.conf(5), nsd-checkconf(8), nsd-notify(8), nsd-patch(8), nsd-xfer(8)

AUTHORS

       NSD was written by NLnet Labs and RIPE NCC joint team. Please see CREDITS file in the distribution for further details.

BUGS

       Zonec  has  rather  weak error diagnostics that will change in further versions.  Zonec expects the input files to be free of syntax errors
       and very little fool proof checks are done.
