Hi lazy admin question

How using Terminal would I issue "Shutdown-h now" command to other machine on network.

I guess what I'm tring to do is take control of Terminal.app on the iMac (10.0.1.x) via airport, so that I can shut down the other machine without physically having to go over there. ?

I have admin on both machines.

Thanks very much!

Airport 'network'
TiBook OSX 10.2.5 (admin)
iMac 10.1.4

Can't you do it through ssh?

I was hoping there might be an easier way? -- SSH seemed complicated at first glance -- but having tried it I discovered it's not so bad after all!! Easier than I thought! Fun even.

However, somewhere there's not an association between the IP address of the other machine and its network name, so I have to look up 10.0.1.IP? as it keeps on changing.

But don't let that stop anyone posting any other solutions...

Thanks

Hmm wonder if I can play or start up iTunes playlists on that iMac remotely -- possible?

There's about a gazillion iTunes-control scripts (generally AppleScript-based) that use Remote Apple Events to control iTunes on a remote machine.

Remote Events have been a feature of the Mac OS for years and years. It's a too-often overlooked feature of the Mac and AppleScript, but it's as easy as:

Code:
set remoteMac to "eppc://192.168.1.1/" -- IP address of remote machine
tell application "iTunes" of machine remoteMac
  activate -- start up
  play -- start playing
end tell

Of course you could substitute the relevant track/playlist/whatever that you wanted to play, but you get the idea.

As for the remote machine shutdown:

shell:

ssh ip.remote.machine shutdown -h now

AppleScript:

Code:
set remoteMac to "eppc://192.168.1.1/"
tell application "System Events of machine remoteMac -- assuming Mac OS X, use Finder for earlier OS versions
  shut down
end tell

Thanks Camelot and Chuckit

The ssh worked great, and was easier than I thought. Got that semi-scripted apart from the password. (Maybe look into DSA keys?)

The apple events -- overlooked like many other mac features -- and something to look into.

Thanks very much for the tips.



PS. what kind of protocol is "eppc" ?

Using keys would certainly save you having to enter a password each time you ssh'd to the remote machine. There's plenty of online tutorials that walk through the steps.

As for eppc://, I forget what the 'e' stands for, but the ppc part is 'process to process communication', a foundation of AppleEvents.

Good stuff this.

Now were cooking with gas. OK well maybe with simple applescripts on the other machine across the network, but a start.

I did try other method and got following response

[localhost:~] borg% set remoteMac to "eppc://10.0.1.2"
set: Variable name must begin with a letter.
Not sure why
