ZFS root fs on FreeBSD 9.0
Gone are the old MFS root fs image and the sysinstall utility. To create a useable ZFS root fs from the 9.0-RELEASE DVD we must specify an alternate location for the temporary zpool.cache file and an alternate mountpoint for the ZFS root fs by using a command like: zpool create -o cachefile=/tmp/zpool.cache -m /tmp/zroot zroot […]

I moved a few months ago. Moving from time to time is probably a Good Thing™. While going through my stuff, I came across a printout of this posting to the freebsd-stable mailling list back in 2007.

At work we have native IPv6 connectivity along with IPv4. We’ve had IPv6 for nearly 5 years and IPv4 for the past 17 years. On 2011-08-16, I grabbed an IPv6-only snapshot of FreeBSD/i386 9.0-BETA1 dated 20110727 and started experimenting with internet life using only IPv6. This particular machine is a virtual machine running inside VirtualBox […]

If you’ve been struggling with booting VirtualBox VMs set up to boot from ZFS raidz{1,2,3} organized disks, then VirtualBox 4.1.x might be the cure you’ve been waiting for. I certainly have been longing for this to happen.

Here’s a summary of the commands I issue when upgrading FreeBSD systems running with ZFS as their root file system.

When moving from one major FreeBSD branch to another, you are almost compelled to upgrade all of your installed FreeBSD ports. If you move from the RELENG_7 branch to RELENG_8, as an example, the old pty interface is deprecated, and ports such as screen (sysutils/screen) must be recompiled and reinstalled to take advantage of the […]

Here’s what I use in /etc/ntp.conf. The restrict lines below originated from Ubuntu. The iburst and maxpoll 9 settings are necessary in FreeBSD to avoid ntpd switching between PLL and FLL modes every now and then.

Jeg tenkte at jeg skulle dele med dere et lite avkrysningsskjema som jeg lagde i formiddag. Det er en god del ting som skal gjøres for hver FreeBSD-maskin i forbindelse med oppgradering. I stedet for å fortsette å bruke Post-It-lapper, så brukte jeg pdfLaTeX og lagde koden for skjemaet som dere ser under. Dersom du […]

Tell rkhunter to ignore /etc/passwd by inserting EXISTWHITELIST=”/etc/passwd” in your rkhunter configuration file. If you prefer not to make this change to your configuration file, make sure you run rkhunter –propupd with the same PATH as given in /etc/crontab. A command like env -i PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin rkhunter –propupd should suffice. Thanks to Mr. Torfinn Ingolfsen for […]

It’s meaningless to check the syntax of Apache’s configuration files more than once during the same invocation of the startup script for Apache 2.2.x on FreeBSD, when the specified action is, say restart or graceful. Here’s a small patch.
