Use this as an example on how to start the virtual console without the need of Java Web Start or accessing it from the web interface.
You can use the user and password that you use for the web interface.

You need an old JRE... I used 1.7.0_80 from the Server JRE package, also I have tested successfully 1.7.0_79 with MacOS.
You don't need to install it, just extract it or copy the files in "jre" folder.

Open the viewer.jnlp file that you get by launching the virtual console from the web interface with a text editor.
Note the urls to the jar files. Download the main jar file avctKVM.jar and the libs for your operating system and architecture.
Extract the dlls (.so Linux, .jnilib MacOS) from the jar libs.

Introspecting a file on ZFS

Derived from: http://www.c0t0d0s0.org/archives/7485-Find-out-in-depth-information-about-a-file-in-ZFS.html

Sometimes you need to acquire in-depth information about a file that isn't exposed by other commands like stat.

ZFS allows you to do this with zdb. However there's a confusing problem. If you're just trying to access a file on your root pool that doesn't have any nested datasets, you need use rpool/ instead of just rpool (assuming "rpool" is the name of your root pool).

Here's 3 examples of acquiring information on /filepath.
