More in my tale of the xen-server. My goal is to run Lotus Domino on this box, and the last installment saw the server coming up, waiting to be configured. Well, it turns out, that IBM presumes that you have X installed on your servers, because it wants to setup the server using a Java frontend. So, the first task is to setup X on the virtualized Host. Giving your Xen instances a working X setup takes care of that nicely. I found Chicken of the VNC to be a really nice VNC client for the Mac. Then I had some problems getting the Notes server to start, but (in turn) that’s what helped me: ...

Get the 6.5.4 TAR file from notes.net and copy it to your Debian server. Here’s my /etc/xen/notes.cfg: kernel = "/boot/vmlinuz-2.6.12-xenU" memory = 384 name = "notes" root = "/dev/sda1 ro" vif = ['mac=00:00:00:00:00:01, bridge=xenbr0' ] disk = [ 'file:/home/xen/domains/notes/data.img,sda1,w', 'file:/home/xen/domains/notes/swap.img,sda2,w' ] To distinguish in which environment to type the following commands: host # means the “physical” host machine while notes # means that you are in a shell in the virtual domain. ...

Sauron, my faithful basement server got another 512MB of RAM, and I plan to virtualize it to run multiple servers on it (most notably a Lotus Domino Server). This is the “step by step” account of how to install XEN 3.0 on it Fixing the size of the root partition My root partition was just a tad too small, so I was stuck with the installation. The solution is rather simple: ...

Improving my datacenter in the basement, I installed a proper Firewall instead of the dinky 4-port NAT router that connected our house to the wild intranet. I used an Astaro Security Linux on an old PC, a setup that has served me well in the Office network. To make everything look really good, I used red and green network cables that I had salvaged from somewhere. Installing the firewall was straightforward, I copied the settings I use at the office and just changed from PPPoE (ADSL) to Ethernet Interface (Cablecom) and was set, more or less. ...

Ray Ozzie, now CTO of Microsoft, then founder of Iris and Groove, has been doing some interesting work on the way, the web enables inter-app communication. His latest endeavour is Live Clipboard a way to bridge communication between web apps or web apps and desktop apps. There are a number of demo screencasts that show how this works. As usual (?), Ray is licensing this under a Creative commons license so we all can share the fun. ...
