If you trust your users well, you might feel slightly less anxious and allow your users to create new filesystems below their own home directories. Continue reading ZFS Delegated Administration in FreeBSD
Last year we had the World IPv6 Day on June 8, 2011. This year we’ll have the World IPv6 Launch on June 6, 2012.
According to this joint press release by Akamai Technologies, Inc., AT&T, Cisco, Comcast, D-Link, Facebook, Google Inc., Internet Society, Internode, Limelight Networks, Microsoft Bing, Time Warner Cable, and Yahoo!:
Major Internet service providers (ISPs), home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6 for their products and services by 6 June 2012.
The hard question is: Are you prepared? Continue reading Are you prepared for the World IPv6 Launch on June 6, 2012?
Every non-key attribute

the whole key,
and nothing but the key, so help me Codd.

Here’s a conundrum aimed at those dabbling in the internals of Microsoft Windows 7. Continue reading Persisting IPv6 DNS resolver addresses
One of my systems is running FreeBSD/amd64 9.0-STABLE and is using ZFS for all its worth. The amount of installed memory in this system is 8 gibibytes, which should be enough to please even ZFS’ ARC. After a few hours of uptime not everyone are happy, and one of those unhappy guys are GnuPG. Continue reading Not enough room for wired pages?
Credit goes to George Mamalakis for raising the issue and to Marco van Tol for the solution. I’m just a simple bystander in comparison to these two, fine gentlemen.
Below are my notes from a simple experiment performed late this evening demonstrating one way of making ZFS grow its pool size. The experiment is based on George Mamalakis’ setup as explained in his post linked above. Note, some system administrator’s liberty has been applied. Continue reading Resizing mirrored ZFS root pool
As I continue exploring the nearly endless possibilities within ZFS, I figured it would be neat to have periodic snapshots of my mail files. The “Interweb” is filled with various shell scripts for this purpose, and I guess another one won’t make much difference. Continue reading Periodic ZFS snapshots
A collegue’s desktop computer has twice lost touch with its DVD drive. The drive is OK, it’s recognized by the BIOS, it even booted from a FreeBSD DVD when told to do so. Yet Windows 7 refused to display the drive. The Device Manager utility complained about a missing driver service and something about a code 39 error. A surfing expedition revealed this article which gives some pretty accurate suggestions. Continue reading CD/DVD drives in Windows 7 and code 39 error
It’s amazing how easy it’s to lock oneself out from doing anything usable in Microsoft Windows. This particular operating system should be more careful of protecting its handling of executeable files. Continue reading Abolish bad legacy systems
The switch to new hardware finally happened. This is the first server to run FreeBSD/amd64 under my supervision. ZFS is used for all storage on this server. I chose to install the newly released FreeBSD/amd64 9.0-RELEASE, before upgrading to FreeBSD/amd64 9.0-STABLE by source. It’s just a matter of preference, given my 13-14 years of experience with FreeBSD. Continue reading New server and first attempt at running FreeBSD/amd64 with ZFS for all storage
