I’ve written before about how to access SNMP agents (or other TCP or UDP services) in a network when you only have SSH access. Running a SSH VPN and then running IP Masquerading (NAT) in the remote end is the solution for me so far. Here is how it is done.

I’d like to recommend an Android App for seeing the Sun’s path in Augmented Reality (AR): Sun Surveyor. There is also Sun Seeker for iPhone/iOS, which I haven’t tried since I don’t have an iPhone.
We’re out looking for a house to buy, and for me getting the afternoon and evening sun on the terrace during summer is so incredibly important. This way, I don’t have to take the real-estate agent’s word for where the sun goes down in the summer and whether the trees will create shade on the terrace. I can check it myself. Über-cool!
The graphics are laid out on top of my phone’s camera image, so given the image to the right I can see that on July 9th (almost mid-summer) the sun clears the wall just after 7pm before it goes down at 8:52pm. A little before that it will be obstructed by the wall in the background though. All visible on one screen.
I guess this could be handy for photographers too, but for buying a house this is indispensable. What surprises me is how all the real-estate agents that I’ve shown it to were blown away by it (or so they pretended :-)) but had never seen or heard about something like that before.
Have fun with it!
