Use networksetup to change AirPort networks from the command line

Great tip,

however i normally conect with the "apple external modem" and was wondering if there was something similar available.

It used to be apple-script-able in tiger.
thanks

Is there any way to combine all of this to write a little script that automatically changed your network location based on the network you're connected to? yes, I'm aware of things like Marco Polo et al., but they're mostly buggy and crash repeatedly on Snow Leopard (plus they have too many features).

The most useful adoption of the networksetup command I found was combining it with ssh to switch a ssh-proxy on and off from the command line. Assuming you have nothing running on port 1080 you just need to tell your computer on which interface to setup your proxy; unless you change your proxy you´ll only need to run the following command once:
sudo networksetup -setsocksfirewallproxy airport localhost 1080
From then on, you´ll need to fire up a ssh-tunnel (best in combination with keypairs) to your host and turn the proxy on:
ssh -ND localhost:1080 username@hostname & sudo networksetup -setsocksfirewallproxystate airport on
will return the pid of your tunnel and turn the proxy on. Afterwards turn it off with
sudo networksetup -setsocksfirewallproxystate airport off
and shut down your tunnel with
kill pid
where pid is the number returned before.

This was a huge help for something that has been bugging me - how to get the name of the current network to use in GeekTool. This hasn't worked since Snow Leopard, and was able to get it to work - here's the script to identify the current network in case anyone is interested:
------------
#!/bin/sh

myvar1=`/System/Library/PrivateFrameworks/Apple80211.framework/Versions/current/Resources/airport -I | grep -e " SSID:" | awk '{print $2}'`

echo "Network : $myvar1"
------------

Enjoy!

" (sidenote: Google does not offer nearly specific enough options for this. Your choices are: anytime, paste 24 hours, past week, past month, past year. What I wanted was "Only since August 28, 2009, the date when Snow Leopard was released.)"

Missed the Google update, hm? The option you are looking for is right on the new results page, on the left-hand side: click on "more search tools" and "custom range...". There you are.

Great tip. Worked like a charm. Although I had to precede the command with a sudo. Couple of questions.

Can you elaborate on the use of 'airport -s'? Can't get it to work.
Is there a way to control other check boxes such as "remember network...", "disconnect when logging out" etc. using this command.

Thanx

I would love to know how to turn on Internet Sharing from the command-line! I've found some old hints but they didn't seem to work.

With the regular Google search results, you can specify an arbitrary date range using the sidebar. Weird that the advanced search is less advanced.

This is really weird, I just found that last night and was playing around with it. TUAW, are you spying on me??
