As long as these [...]]]> Well, there’re few prerequisites to this method:

1. You should have a DMZ’ed (or accessible from outside world in some way) server running in your home network which you can SSH into.
2. Your home Mac should be on (you can use etherwake command from within your network to wake it up first).

As long as these two criteria are met, you simply do:

laptop:~ kirillov$ ssh -p19322 -L59000:imac:5900 user@home.selfip.org -fN

The bit

-p19322

you need only if you’re running your SSH daemon on a non-standard port (or your forwarding is set from a non-standard port); either way, it is highly recommended. This piece

-L59000:imac:5900

says “I want to forward all requests coming on port 59000 of my localhost to host imac in the target network, port 5900” (which is a default VNC port). Finally,

my_home_username@myhomeserver.selfip.org -fN

is pretty straightforward, “-fN” says “go to background right after asking for login and password if they are needed”.

After you’ve done that, all you need to do it to hit ⌘K in your Finder (or start a dedicated VNC application) and do:

After that you’re likely to be asked for login and password, which, by coincidence will be login and password from your home Mac. And you’re in!

What is it anyway? Here you go: [...]]]> No, really, have you seen it at all? I bet you didn’t because otherwise you would’ve tell the world about it — I’m using it for quite a while now, and I can firmly say: this is a program which just works, and makes my life substantially easier.

What is it anyway? Here you go: I think the screenshot is pretty much self-explaining:

As it follows from the name, it’s initial purpose was to track GPS trails of your running, but now it could do much more than that. In short words, it allow you:

1. Plan routes for cycling, running and hiking, drawing it on the map and uploading to a GPS of your choice.
2. Importing and analysing your records from GPS — so you can view not only the route itself, but also elevation, pace, speed and so on.
3. Manage your own library of favourite routes, which you can adjust and load to GPS
4. Show your routes on different background maps, including Google Maps Satellite, Terrain, Streetmaps, and also OpenStreetMaps and Bing Maps (wow!).
5. Share your routes on EveryTrail.com (which I personally adore) and GPSies.com
6. And so on, and so forth, so go and check the list yourself at trailrunnerx.com

TrailRunner is donationware, and I most definitely consider donating to author — this is so great, when somebody creates a really useful piece of software which just works.

Now, I’m not different in any sense. Instead of writing an Image-Based Information Processing lecture (which puts me to sleep almost immediately — or is it the professor who does it?) I’ve managed to get a VNC working on my Mac. On my home Mac. Well, it all started with the TeamViewer, which suddenly stopped to work. It was disappointing, as I couldn’t play with Boxee on my home computer during the lecture anymore, so I’ve tried to invent something. Indeed, I could SSH into my iMac (via a resident NAS which acts as an SSH gateway to my home network). What I ended up doing could be best described by these commands:

imac$ sudo port install tightvnc
imac$ vncserver ... password ... verify ... your VNC server is running on iMac:1
nas$ sudo ssh -f roman@imac -L 5901:localhost:5901 -N
macbook$ ssh -f my-nas-username@my-nas-host 5901:127.0.01:5901 -N # it didn't work with localhost here

Then I simply used JollyFastVNC to VNC into my iMac by connecting to 127.0.0.1 and port 5901. Yay! However, ten minutes later I realised, that in fact I can set up a tunnel to my Mac’s default (bundled) VNC server on screen 0. So I did — and apart of the fact that I should’ve enabled monitor mirroring (otherwise it tried to skew my iMac’s monitor + my HD TV connected to it into one rectangular window, which didn’t look neither pretty nor comfortable), it did work quite good. That works and an only question I ask myself – why on Earth do I need it if TeamViewer has started working again?
