Think I’ve had this page open for a while now, and I can’t remember whether I had linked to it previously or not… so I guess I’ll go ahead and do it so I don’t lose it. Interesting solution for truly large scale monitoring. I need to spend some time with some of the MQ apps, I can see a lot of things they would be useful for…
As I mentioned in an earlier post, I bought one of these little 4-port wireless routers with a gigabit switch to use primarily as a NAS server. I’ve been so happy with it that, when I recently discovered the need for a light duty broadband router and firewall on a loaner basis, I decided to pick up another one. With the original, I took the firmware to a Tomato version and I have found it very pleasant to work with, so I plan to do the same. I recall having a few problems getting it where I wanted it to be, so I’ve decided to make some notes on my steps through the process this time around. I think I may have actually attempted a direct flash to the Tomato firmware the first time, and had to perform a recovery, so I’m going to “follow the directions” this time around 🙂 Much of the instruction comes from the FatWallet forum thread at http://www.fatwallet.com/forums/expired-deals/1180400/?start=0, and specifically this post and (primarily) this post on page 3 of the discussion. There’s also a good link discussing recovery in between those two posts should you happen to brick a box. I just wanted to clean these up and put them in a slightly more organized fashion than sometimes happens in a forum thread, as well as document the steps that worked for me.
Please note that I disclaim any and all liability for any damage or loss, direct or indirect, as a result of these instructions. These notes are primarily for my own benefit and may or may not work in your individual circumstances. You acknowledge that installing third party firmware is an unsupported action and accept full responsibility for any problems or costs resulting therefrom.

Instructions are for the Belkin Share Max N300 (F7D3301/F7D7301) v1.
The two DD-WRT files are out of order when you browse for the files (mega is alphabetically before mini… keep it in mind)!
30/30/30 reset method: Hold down reset button for 30 seconds. While continuing to hold reset, power off by unplugging from wall outlet and leave unpowered for 30 seconds with reset held. Without releasing reset button, restore power to modem; wait 30 seconds, then attempt connection to web interface again.
Just recently read about the spice protocol for remote display/audio/etc, and it looks very promising. Finally got my new build system up and running on Ubuntu (turns out that “nomodeset” as a kernel option was key to that, and had to work around through a few hoops… still not sure whether it’s running UEFI or typical, but it’s running, so I’m done caring). Next step is to get a couple of virtual machines running, and see if I can justify shutting down a couple of other systems and end up saving power, as I suspect my new build is quite a bit hungrier for juice than the miscellaneous small boxes I currently run. Will have to hang the Kill-A-Watt off it at some point and test to be sure.
I’ve been watching this space for a while, and I continue to find it frustrating. Virtual Computer’s NxTop was one of the more promising platforms to develop into what I’d really like to see this area of computing become: a type 1 virtualized environment capable of running multiple operating systems simultaneously (much like the existing server virtualization environment) with the ability to display consoles for the running guests (which is lacking in the existing server environment), and perhaps eventually provide direct guest access to certain devices such as video cards to achieve maximum performance from that component. XenClient/XCI was the other promising platform in this area, so hopefully Citrix does see this as an opportunity to develop and build out a product (hopefully without leaving open source behind… I see a lot of advantages in being able to run something like this at home too) rather than just an opportunity to swallow some competition and further entrench the VDI model, which I find immensely unpalatable.

Keep in mind for Linux-based infrastructure.
