Re: [zones-discuss] dhcp zone
A local zone can be a DHCP client/server if you can use IP Instance: http://opensolaris.org/os/project/crossbow/faq/#ipinst_dhcpclient -- Renaud Caroline Carol wrote: Hi all, Is dhcp working in local zone ?

Re: [zones-discuss] dhcp/zone
Contrary to what everyone else says, with a bit of customization dhcpd can run zones just fine. Solaris 10 update 3 and later (I forget which Nevada build) have all the required bits in place. http://mail.opensolaris.org/pipermail/install-discuss/2007-March/004266.html Yep, it can be made to work, though I don't think it's officially supported. When I last looked at this issue, the changes needed to the source to make it work without any special tweaks was straightforward. If you offer up hints, I make take this on in the future. I've got a couple other things I want to work on before this one, though. It's been a while, but the main things I recall are: * The DHCP server used to open /dev/ip rather than using a UDP socket to do some control operations, which forced it to require more privileges than it really needed. This was fixed via 6357132 in Nevada build 36. * The DHCP server is generally designed to work with physical IP interfaces. Some work would be needed to allow it to work with logicals (if that's even desirable); 5030697 touches on this. * The DHCP server doesn't support different IP subnets on the same IP interface, which constrains the way things could work with zones. This is covered by 5010613. * The DHCP server populates the ARP table so that it can unicast DHCP responses to the client before the client has agreed to use the IP address (this is basically due to the same DHCP RFC braindamage I described in PSARC/2007/571). If it can't install an ARP entry, it will broadcast the response instead, which will work fine. So it may be sufficient to simply lower the log level of those failures. -- meem ___ zones-discuss mailing list zones-discuss@opensolaris.org

There is an interesting support issue for Trunking and/or Aggregation that needs to be addressed to support of ce and ge by GLDV3. Working with Zones and Containers is primarily for a consolidation effort that will demand network bandwidth. We have been using Trunking and IPMP to layout the best of the network infrastructure for perfomance and availability. Solaris Trunking 1.3 does support ce and ge, unlike Solaris 10 Aggregation (dladm). Since dladm is the focus for future network administration among all the other features builtin for supporting IP-instances, where Aggregation is a sub function of, isn't it prudent to be strategic reason to push for the support of ce and ge by GLDV3 ?

That'd be one good way to do it. The other way is via Clearview's UV shim layer, which will eventually make legacy DLPI devices appear to be GLDv3 drivers. I'd rather see these old drivers ported over to the new framework, but that's a cost/benefit analysis that others (partly the maintainers of the driver) need to make. (And, unfortunately, many of these old drivers are closed-source, so it's harder to find people to help out.) -- James Carlson, Solaris Networking [EMAIL PROTECTED] Sun Microsystems / 35 Network Drive71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 ___ zones-discuss mailing list zones-discuss@opensolaris.org
