I would like to monitor my server on my desktop computer with the GKrellM-utility. I would also like to have it run over ssh, so that it can run over the internet without being open to everyone. So here’s what I did:

• First step is to set up key-based passwordless login.
• Install gkrellmd (gkrellm-server). As I use debian I type “apt-get install gkrellmd”. Use your flavor of package-manager.
•  (optional) Edit /etc/gkrellmd.conf if there’s anything you’d like to change. The default works perfectly when using SSH-tunnels, because it looks like you’re running from localhost. If you don’t want to run over SSH you could add your desktop’s IP in allowed-host. Restart gkrellmd if you have changed the config.
• Now open a SSH-tunnel on your desktop to your server. The text in red you should change to your wish, and the text in green is OK if you didn’t change anything in the config-file.
• ssh -N -f -L 19150:127.0.0.1:19150 user@server
• The red number is the local port which leads to your tunnel. If you want to monitor more than one computer you’ll need to change this number to an available port (check with netstat -nt). The red text is of course your user login on the server.
• run: 
• gkrellm -s 127.0.0.1 -P 19150
• The red number should be the same as above.
• GKrellM should pop up and do it’s thing

What can you tell about someone who takes backup of his backup?

That he’s using Windows.

The new Windows Home Server has serious trouble which can lead to corrupt files. This OS is often used for backups and as a shared point for files. Microsoft has not fixed this issue yet, but recommends to take backups before putting anything on the server. So basicly, you’re taking backup of your backups.

I’ve just finished the new game Portal, from Valve. It’s pretty much about making Portals, and using them to solve puzzles. But the portals are a really spectacular method of doing stuff. You can do pretty much everything with just placing 2 portals somewhere, and walking/jumping into them. If you’d like a short preview, watch this video.

You start of at simple training, where you walk trough a portal, and simply picking up objects. Then you advance step by step, learning how to do things. Later you are tested in these skills, and you have to find your way to the goal. The problems get more and more complex, but not so hard if you just use a few minutes to think first. The game is over too quickly tho, but I think that’s better than dragging the story even further. Now people will want more, and try the bonus challenges, and probably the sequel (of some kind) that they talk about in the commentary. There are some extra material to do after the story, like challenges, advanced tests, achievements and commentary from the makers.

One of the fun parts about the game is the story, and the computer that communicates with you while you play. Her name is GLaDOS, and has a very dark humor that probably will make you laugh. I recommend turning on the subtitles, as it’s sometimes hard to hear what she’s saying.

So… I really recommend this game. It’ll make you laugh, think and have fun. I really did!
