This Tutorial will give you a run down on how to create a VMware using FreeNAS. The tutorial comes with screenshots and covers installation of FreeNAS, setting up an iSCSI target and connecting to it from Windows.
PC-BSD has the Warden GUI to install and maintain jails. Setting these up can also, and I’m sure many would prefer this way, be set up from the console. Cyberciti.biz has published a useful and extensive guide:
How do I setup operating system-level virtualization that allows me to partition my FreeBSD-based server system into several independent mini-systems called jails.? I’d like to set one jail for mail and another for web server via 2 public IP address.
Each jail under FreeBSD virtual environment runs on the host machine with its own files, processes, user and superuser accounts. From within a jailed process, the environment is almost indistinguishable from a real system. The easiest way to set, create and modify jails is using a framework called ezjail.
Martin Wilke has a useful step-by-setp guide (via bsdgroup.de) to install FreeBSD 8.0 (stable version yet to be released) from a USB pendrive:
dd if=/dev/zero of=/dev/da0 bs=1k count=1bsdlabel -Bw da0 autonewfs -L FreeBSD /dev/da0amdconfig -a -t vnode -f 8.0-HEAD-20090609-JPSNAP-i386-dvd1 -u 0 && mount -r -t cd9660 /dev/md0 /mnt/isomount /dev/da0a /mnt/USB-Stickcopy all files from your mounted cd in to your USB-Stick, after that you need to create a fstab for your USB-Stickvi /mnt/USB-Stick/etc/fstab and put following in:/dev/ufs/FreeBSD / ufs ro 0 0
The FreeBSD Security Team has issued the following security warnings:
- FreeBSD-SA-09:11.ntpd – ntpd stack-based buffer-overflow vulnerability
- FreeBSD-SA-09:10.ipv6 – Missing permission check on SIOCSIFINFO_IN6 ioctl
- FreeBSD-SA-09:09.pipe – Local information disclosure via direct pipe writes
For background info, problem description, impact, workaround and solutions, have a look at the individual advisory pages.
Today Virtualbox was committed to the FreeBSD ports tree. After a lot of work we had a good discussion today about how stable Virtualbox is, and after the CTF with take6 we got a lot of good feedback, so it was time to commit. Please READ the pkg-messages carefully, as well as the wiki page.
Manolis Kiagias has announced a project that he has started: Building custom FreeBSD ISO’s:
I believe this list (and probably the forums) would be the best place to announce one of my little projects, namely the building of custom FreeBSD install discs (DVD sized for desktops, CD sized for servers) with the latest release and updated packages.
I have been experimenting lately with ‘make release’ and ports’ building using ports-mgmt/tinderbox. I am using a dedicated system for building the base system and packages. The purpose of this experiment (besides the educational value of it) is to allow me to build FreeBSD discs with custom and up to date packages. These will in turn reduce
significantly the amount of time required to install new systems (esp. desktops which need hundred of packages).
This is just short of 1GB and contains the following:
– – FreeBSD 7.2-RELEASE base system (standard bootable / installable disc)
– – Selection of custom packages that can be installed either during installation via sysinstall or at a later time (again using sysinstall or pkg_add etc).
Many other useful packages are also included as dependencies of the ones listed above. This iso does not contain openoffice (to keep the size smaller) and multimedia apps (to avoid licensing problems). Future versions of the builds may have broader / different selection of packages, depending on the feedback received by the community.
Installation is no different than an official FreeBSD CD, other than when you reach the package selection screen, you will be shown the custom set of packages. The ports tree included in the CD is the one used to actually build the packages. I will soon upload a tarball with the options used – not all packages where built with the default options.
The whole announcement can be read here.
Kip Macy has committed a couple of long-discussed patches to ZFS on FreeBSD current (and 7-Stable) to increase its stability. Most paches are similar to those on OpenSolaris, and they should bring FreeBSD up to Solaris ZFS level with regards to performance and stability.
- the recurring deadlock was fixed by deferring vinactive to a dedicated thread
- zfs boot for all pool types now works
- kmem now goes up to 512GB so arc is now limited by physmem
- the arc now experiences backpressure from the vm (which can be too much – but this allows ZFS to work without any tunables on amd64)
- frequently recurring LOR in the ARC fixed
- zfs send coredump fix
- fixes for various PRs
This is a presentation by George Dafernos at the Oekonux Conference (Manchester 2009). Some interesting statistics with regards to FreeBSD developers, releases, productivity etc etc.

FreeBSD’s jails technology has been updated with an interesting new feature:
Add hierarchical jails. A jail may further virtualize its environment by creating a child jail, which is visible to that jail and to any parent jails. Child jails may be restricted more than their parents, but never less. Jail names reflect this hierarchy, being MIB-style dot-separated strings.
