[OpenIndiana-discuss] DHCP server for IPV6

2012-06-07 Thread Gary Gendel
Moving from IPV4 to IPV4/IPV6 on my home network is like peeling an 
onion, so I'm taking it one step at a time. :(


Currently I only see the old Solaris dhcp server for OI.  Can this 
handle ipv6? I couldn't find any examples but ipv6 support was 
superficially mentioned in some documents I came across.  Is there a 
howto document available?  If not, do we have a supported install 
package for ISC DHCP now that it's gone from SFE?


Regards,
Gary

No.  DHCPv6 is really a very different protocol from IPv4 DHCP.

(Are you really sure you need DHCPv6 ... ?)
My ISP provides me with both an IPV4 and an IPV6 address. My OI box 
currently does IPV4 firewall/routing/NAT and provides DHCP service for 
my internal network.  I'm trying to replicate this in IPV6 in parallel 
with IPV4.

When I was designing and testing the DHCPv6 client in OpenSolaris, I
used the WIDE-DHCPv6 server for much of the ad-hoc testing.  The patches
I needed to make it work on OpenSolaris are still available:

I haven't really kept up with it since 2006, so things may well have
changed.

Thanks.  I probably should move to ISC DHCP since that's where Oracle is 
headed as well.  Should I get the sources and build from there or will 
it be available as a package in the near future?

As I said, things are different with DHCPv6.

In particular, although you *can* distribute global addresses with
DHCPv6, I wouldn't necessarily recommend that you do so.  It's a little
annoying to administer, and doesn't really add a whole lot of value over
the standard choices of stateless autoconf (for most clients) or static
(for most servers).

Notably, prefixes (aka netmasks) are not provided by DHCPv6, but
instead by RAs.  If a DHCPv6 server gives out an address, it's just a
bare address with no prefix length.  That makes it quite a bit different
from IPv4 DHCP, because it means that you have to make sure that the
advertised prefixes (in the router's RAs) always line up with the
address pools on the DHCPv6 server.  And there's really no mechanism to
do this other than the administrator's fingers and short-term memory.  ;-}

In a well-managed and large network, I can certainly see a good bit of
value in a DHCPv6 server to make sure that everyone has the right name
server addresses and such, and to centralize the management of static
IP addresses.  It's harder to explain why you'd need it on a home
network ...

As I said, I haven't kept up.  I've been using IPv6 on my home network
for many years (with a tunnel to Hurricane Electric), and haven't really
had a need yet to set up a DHCP server, so it's not a question I've
tried to answer.

Yes, both the Sun and ISC DHCP servers are included with Oracle
Solaris 11.  You have to choose one.  OI has something in the works
for the ISC DHCP server.  It's visible at:

https://hg.openindiana.org/upstream/oracle/userland-gate/file/tip/components

I don't know if it's been made into a package for OI yet.
