The above link shows you how to launch a process when network status changes. &nbsp;You can then launch a script to do what you want using launchctl when the network status goes to down - and likewise restore everything when they plug it in again.

The second script says there's a syntax error somewhere on this line:<br />
<br />
if [[ -z $1 ]]; then<br />
<br />
Expected “,” or “]” but found unknown token.

Can anyone think of a way to lock/logoff/disable an iMac when the network cable is unplugged or it loses network connectivity?<br />
<br />
Our students unplug the network cable in an effort to stop remote control and avoid managed preferences.<br />
<br />
Running OSX Snow Leopard<br />

Any help/ideas appreciated!<br />

Lock/logoff/disable Apple Mac if network cable unplugged

Apple devices including Macs, iPhones, iPods and iPad support standard wired and wireless networking technologies, but they also utilize custom applications and some special techniques for networking with each other and with non-Apple devices. Apple manufacturers the AirPort line of wireless networking products, and has its own networking protocols, AppleTalk and AFP (Apple Filing Protocol).

Apple Networking

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.

Apple OS

Swift is a compiled programming language created for iOS, OS X, watchOS, tvOS and Linux development by Apple Inc. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products. Swift is intended to be more resilient to erroneous code ("safer") than Objective-C and also more concise. It is built with the LLVM compiler framework included in Xcode 6 and later and uses the Objective-C runtime, which allows C, Objective-C, C++ and Swift code to run within a single program. A second free implementation of Swift targets Microsoft's Common Language Infrastructure (a.k.a. .NET) and the Java/Android platform.
