Updating Opensolaris to latest development build

To be able to update from a post Opensolaris 2008.11 release to the latest development build use the following steps:

# pkg set-authority -O http://dev.opensolaris.org/dev development
# pkg refresh
# pkg image-update -v

I have finally found the correct website for the most up to date instructions:

Virtual Iron dead in the water?

Is this true? If so what’s Oracle’s game plan? They just buy Virtual Iron for a virtualization management. Appear to have a clue since they are buying Sun with a huge virtualization skill set and product line. Then this info comes along?

http://www.theregister.co.uk/2009/06/19/oracle_kills_virtual_iron/

In a letter to Virtual Iron’s sales partners, Oracle says it “will suspend development of existing Virtual Iron products and will suspend delivery of orders to new customers.” And in a second letter to a partner speaking with The Reg, the company says it will not allow partners to sell new licenses to anyone – including existing customers – after the end of this month.

So is Oracle’s plan just to cannibalize Sun & Virtual Iron’s code and forsake all the customers they bought?

Makes me pretty sad since I’m a big Sun fan with OpenSolaris and I have the fear that they will do the same thing there.

ACLs and CIFS under OpenSolaris

One of the issues with running a file server in the home is the fact that you have multiple computers and accounts (the wife, the kids etc) accessing the same directory trees. The default user/group works pretty well as you have effectively a single group for family access. Different groups are used for more computer based access needs such as server to server communication. However I found that the kernel CIFS doesn’t create files with proper access very well using the standard UNIX permissions.

ACLs are the solution in this case.

# zfs create -o casesensitivity=mixed -o sharesmb=name=storage -o quota=275G usbpool/storage # cd /usbpool/storage # chgrp home . # chmod A=group@:rwxpdDaARWcCos:fd:allow .

Now when you create a new folder or files under this CIFS folder it creates them with the group permissions. I leave everyone in the same group and can add the secondary group as necessary for different shares needing permissions.

When users create files they are created with:

----rwx---+ 1 me home 7930 Feb 7 2008 test.txt

And when they create directories they are:

d---rwx---+ 2 me home 3 Feb 9 22:10 OpenSolaris

Doable and functional. I still wish there was better documentation that I could find around the ACL permissions and how they work. I’m doing testing and I know I’m missing things.

OpenSolaris 2008.11 & NFS (security?)

iguy — Wed, 04 Feb 2009 03:54:55 +0000

A quick note here after the past 4 hours of fighting with NFS on OpenSolaris 2008.11. If you are attempting to do an mount and get a Permission Denied from either Linux or ESX the solution is rather easy.

Make sure that the IP address that you are connecting with has a reverse DNS entry with a hostname.

That’s it. 4 hours and that’s the gotcha. If you don’t have a reverse DNS you’ll never get the mount to work.
