[Maintain] IPv6 Support

Hi,

Planning to use the tool and I have two questions. Thanking you in advance for the replies.

Is there a support for IPv6?

Can each zone support same subnets?
Example: Have two labs and using the same 10.0.0.0/8 range. Is this supported in the tool?

Regards,
Nick S.A. Nikjoo

Not yet. ISC's DHCP server support for IPv6 is coming along nicely, and
BIND has supported v6 for a while now. It would make sense to allow both
v4 and v6 addresses for a host, but we're not in a rush to use IPv6 at
UW, so my interest is largely, um, academic.

A subnet can belong to multiple zones, as can an IP address range.
Allowing multiple IP address ranges to be defined in a subnet comes in
handy for partitioning dynamic address spaces.

A host can only belong to one zone, so it is possible for the admins of
ZoneA to create host entries that are effectively in ZoneB's address
space but not editable by ZoneB admins.

Nick,

We plan to add support for IPv6, but we'd like to change the database
schema when we do. So.. it's going to be in Maintain version 4.
Probably at least a year away.

That said, we are adding support to build bind files now, so you could
include IPv6 entries from a static file. We'll be trying that out here
at OSU, so I'll let you know how it goes. :)

Is it possible to use this module to just build the "dns.data" without
having maintain try to push it to a remote server? I can't get maintain
to generate the "dns.data" file and would appreciate any suggestions on
things to try/check. If only the BIND support was available currently J

Thanks!

While djbdns uses a single data file, BIND uses a separate data file for
each domain (called a zone in BIND, which is different from a zone in
Maintain) as well as a configuration file which maps the zone files to
DNS domains. The BIND zone files and named.conf configuration file are
written to a directory under the BUILD directory, not a file. The name
of the directory is build_dir in the build_bind section of the
module-specific configuration.

Dawn,

You're 100 correct on BIND :)

Our plan is to run Tiny DNS and have it perform zone transfers to any BIND servers that we can't convert to Tiny DNS.
Does the BIND option for build_dns work currently? I thought it wasn't available yet so we were going to use Tiny DNS in place of BIND for the time being.

Either way, I still can't get Maintain to generate the Tiny DNS config file. I'll check the conf file for the build_dns module and look into using the build_bind utility that you wrote.

Thanks!

Nick,

You don't assign subnets to zones. But you can assign an IP range to
multiple zones. Click on the Admin link and then choose List next to IP
Ranges. Find your range and choose Edit. At the bottom of the page,
you can add the range to as many zones as you want. You have to choose
a default domain, which is something we need to fix, now that I'm
looking at it. The domain you choose needs to already be assigned to
the zone. The default domain only has meaning for dynamic ranges -
since we don't do DDNS, Maintain automatically generates reverse lookups
like 1-2-3-4.dynamic.domain.foo, where "dynamic.domain.foo" is the
"default domain" you specify. Currently, the default domain is
associated with both zone and range, but it should just be tied to the
range. Gah.

Anyway, the steps overall are like this:

* Create subnet
* Create range
* Create domain
* Create zone
* Add domain to zone
* Edit range page to add range to zone(s)

Sigh, we really need a setup wizard. That's on the wishlist, too.

P.S. There's a checkbox on the range page that says "Require all domains
in zone" - I forget what that is supposed to do. Looks like another
legacy thing we need to remove.

Oh, and ouch - there is another bug on the range page - it's not showing
the current settings for a range when you're on the edit action. I'll
file a bug.

Hi Kirsten ,

Your reply and answer is greatly appreciated.

As per my second question; I guess, can not we have same subnets in
different zones

We have multiple labs across various locations, and we all use the same
RFC1918 IP ranges.

We would like to have single server to keep track of all the 10.x.x.x,
172.16.x.x & 192.168.x.x. This means we have multiple instances of
10.x.x.x in other labs.

Thanks,

Nick
