The SCTP protocol provides reliable, flow-controlled, two-way transmission of data. It is a message oriented protocol and can support the SOCK_STREAM and SOCK_SEQPACKET abstractions. The SCTP protocol checks the integrity of messages by validating the state cookie information that is returned from the peer.

FreeBSD Can Compete With Ubuntu Linux, Windows 8
The NVIDIA BSD performance is very good for OpenGL as shown in this article with a comparison of Windows 8 vs. Ubuntu 13.10 vs. FreeBSD 9.1. In fact, for some OpenGL workloads the Linux games are running faster on FreeBSD/PC-BSD 9.1 than Ubuntu! [Phoronix]

Apple’s Operating System Guru Goes Back to His Roots
Hubbard left Apple last month to return to the world of open source UNIX, taking the chief technology officer post at a iXsystems, a company that offers servers and other data center hardware that runs FreeBSD. Apple was quite an education, and now, he wants to bring the “Apple approach” back to the open source game. [wired.com].

DNSSEC @ MDLUG.org

FreeNAS 9.1 has been released. We have read the blog posts, the press releases, and we probably all agree that this FreeBSD based NAS is becoming better and better with each release. FreeNAS is still ‘growing up’ and new features are added to each new version.
Since FreeNAS is still changing so much, maybe be developers can do something about the GUI side of things, i.e. the Web Interface.
The goal of FreeNAS is to simplify complex admin tasks in the underlying FreeBSD (nanobsd) base through a poin-and-click Web Interface: volumes can be created, permissions changed, data sharing turned on/off, music/video streaming set up, and most, if not all, ZFS features are included.
All this makes FreeNAS a powerful network attached system (NAS), especially if you consider it is open source and free to download, but I think the Web Interface can still do with some TLC as it can be confusing and is not always newbie friendly.
There are 6 menu buttons (top left) linking to “System”, “Network”, “Storage”, “Sharing”, “Services”, “Plugins” and “Jails”. In the Menu tree, under this bar, you will see the same (and more) links, unnecessary duplication. If “Account” is one of the main menus, why is this then one on the right hand top side, and not on the left with the others?
When you close / log out of the FreeNAS Web Interface and go back in, the menu tree is left expanded as it was left. It looks nicer if the tree was collapsed each time you open up the GUI.
Every time options are saved or when you cancel a screen, the whole menu tree is reloaded/refreshed, which takes about 1-2 seconds. This could be due to some settings or limitation in the Django framework, but it is annoying.
When you go into some of the (sub)menus and make changes, a tab gets added to the tab bar (top right), next to “Reporting” | “Settings” | “System Information”. What is the point of this? You’re not going to use your NAS GUI for hours (usually). You make the changes and come out of it. There’s no need for these shortcuts.
For new users of FreeNAS, it would be helpful if there was a short introduction with some step-by-step instruction on the first screen to help them set up the basic things (User, Volume, Privileges etc). Yes, there’s the FreeNAS handbook with everything set out step-by-step, but judging from questions on the FreeNAS forums I guess there are more users that don’t read through the manual than those who do.
Personally, I prefer the old FreeNAS 0.7 horizontal menu. It was, and is now in NAS4Free, easy to use and straightforward, with no duplication. The other thing I like in NAS4Free, is that you can make all changes on the opened screen, i.e. there are no pop-up windows with yet more settings.
I appreciate a NAS GUI is not something you need every day. In an ideal world you install and set up your NAS and let it then run (headless), but there are still some areas where FreeNAS should improve to avoid confusion and duplication.
If you have no need to install or use FreeNAS, but are still interested to see what it looks like, have a look at the screenshots below (click on the pictures to magnify).
Glen Barber has announced the first release candidate build for the FreeBSD 9.2:
The first release candidate builds of the 9.2-RELEASE release cycle
are now available on the FTP servers for the amd64, i386, ia64, powerpc,
powerpc64, and sparc64 architectures.
Changes between -BETA2 and -RC1 include:
Expand the list of devices claimed by cxgbe(4).
Fix a panic in the racct code when munlock(2) is called with incorrect values.
Remove ctl(4) from GENERIC. ctladm(8) now automatically loads the corresponding module as necessary. This reduces the default memory footprint and allows FreeBSD to work on i386 machines with 128 MB of RAM out of the box.
Fix zfs send -D hang after processing requiring a CTRL+C to interrupt.
