From MacOSXHints…<\/a><\/p>\n

At my office, I needed to find a way to turn of the wireless network when someone plugged in their network cable. I also did not want them to be able to turn the wireless network back on until the network cable was unplugged. I came up with the fallowing solution.<\/p><\/blockquote>\n

I created a launchDaemon called com.companyname.ethernetmonitor, and saved it in \/System\/Library\/LaunchDaemons:<\/p>\n

<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<!DOCTYPE plist PUBLIC \"-\/\/Apple\/\/DTD PLIST 1.0\/\/EN\" \"http:\/\/www.apple.com\/DTDs\/PropertyList-1.0.dtd\">\r\n<plist version=\"1.0\">\r\n<dict>\r\n  <key>Label<\/key>\r\n  <string>com.companyname.ethernetmonitor<\/string>\r\n  <key>ProgramArguments<\/key>\r\n  <array>\r\n    <string>\/Library\/Scripts\/CompanyName\/turnOffAirport.sh<\/string>\r\n  <\/array>\r\n  <key>WatchPaths<\/key>\r\n  <array>\r\n    <string>\/Library\/Preferences\/SystemConfiguration<\/string>\r\n  <\/array>\r\n<\/dict>\r\n<\/plist><\/pre>\n
This will watch the System Configurations folder for changes. This folder changes when you plug in a network cable, turn on AirPort, etc. When it changes, a script called turnOffAirport.sh, stored in \/Library\/Scripts, is run to see if the Ethernet connection has a company IP address:
\n#!\/bin\/sh
\nif ifconfig en0 | grep 155.144;
\nthen \/usr\/sbin\/networksetup -setairportpower off
\nelse
\nexit 0
\nfi
\nThis helps keep the user from grabbing two IPs (our wireless and wired network use the same set of IPs), and also helps prevent a few other odd issues when a user is connected to both wireless and Ethernet networks.<\/p>\n
\n
I suspect that this can easily be made to work both ways…  At the present time, it appears to turn off the wireless, but not automatically turn it back on.<\/p>\n
That could be by design.  After all, the laptop will be consuming more power with wireless turned on….  But, I believe by changing the exit 0, to \/usr\/sbin\/networksetup -setairportpower on<\/strong> would be enough to change the behavior…<\/p>\n","protected":false},"excerpt":{"rendered":"
