	[[w:netcat\|Netcat]] is a flexible network utility for network access to ports on computer systems. It can connect to a variety of ports, by either TCP or UDP. For pre-ARM LinkStation (LS1,LS2,LS-HG) owners with UBoot 1.2.0 installed, it provides one with "NetConsole" connectivity and the means to do a variety of tasks, including controlling the boot process, altering environmental variables, and flashing data/images to ROM. The official site for Netcat is [http://netcat.sourceforge.net/ here].		[[w:netcat\|Netcat]] is a flexible network utility for network access to ports on computer systems.

		+	'''Note:Currently the stock UBoot 1.1.1 that Buffalo/Melco/Revogear provides on ARM-based machines (like the LS-Pro and KuroPro, for instance) was compiled with the '-tiny' flag, so it doesn't provide some of the features that we enjoy on the custom UBoot ported to LinkStations back in mid-2006 by linuxnotincluded. Several developers here may be working on an upgrade to the stock UBoot on these ARM-based boxes. If and when such a new UBoot is developed and released, it will be announced here in the Forum, most likely. Until then, if you want to control UBoot behavior, your options are probably limited to Serial Port access and using the "nvram" program that is in the stock firmware. As is the case with any alterations to your LinkStation, proceed with caution, double-check what you are doing, and have a backup plan.'''

	The version of UBoot that I downloaded and installed for my HG and KuroHG has the 192.168.11.x setup as its defaults. Since my home network is set up with 10.0.1.x IP addresses, I decided to use Netcat and UBoot to change my env vars so that I wouldn't have to switch the KuroHG (my lab rat) to the 2nd port on my computer (with 192.168.11.x address). I could just leave it on the main network all of the time, and get Netcat-UBoot control whenever I wanted it.
