One of the basic ways of connecting to a FreeBSD server is through a secure shell, commonly referred to as ssh. The most basic usage of an ssh connection is to give you a full-fledged command prompt on the remote machine. However, the ssh connection can also be used as a tunnel for countless other things, […]

Expanding a ZFS pool
In an earlier post, I explained how it was possible to grow a ZFS pool by replacing all disks one-by-one. In that post, I also mentioned that if you have enough spare connectors available, you can easily expand the pool by adding another array of disks. A while back, I had replaced a bunch of older […]
Instant onChange with IE checkboxes

Some of these are just plain stupid, but some are simply different ways of interpreting the standard. A good example is the onChange event. This is a simple event, commonly […]
Growing a ZFS pool
I run several fileservers using the excellent ZFS filesystem. While originally a Solaris invention, it was successfully ported to FreeBSD for version 7. It is extremely well suited for large fileservers due to a combination of reliable software RAID (modes 1, 5, and 6), checksumming and snapshots. Combined with the option of nested filesystems and […]

Replacing bad motherboard capacitors
Now, this is a problem that likely won’t affect you if you either replace your PC every 2 years, or don’t use it very often. However, if you’re like me and build your machines to specs that’ll set you for five years, and then keep them on 100% CPU load 24⁄7 for those 5 years (thank you, […]
Useful Unix Units: Screen (part 1)
Ok children, time to learn about screen, one of the most useful little Unix tools available today. First, let me get this straight: I don’t believe in the ‘one OS to rule them all’ crap. Horses for courses, and for server work, my horse rides a command line FreeBSD install. Digression: I’ve never much seen […]
