Disconnecting the LAN when the screensaver kicks in

Question

Are there any utilities that will disable my LAN connection when the screensaver kicks in?

Answer 1

For what operating system?

In linux you should be able to do something similar to

#!/usr/bin/perl
#gnome
my $cmd = "dbus-monitor --session \"type='signal',interface='org.gnome.ScreenSaver',member='SessionIdleChanged'\"";

#kde
my $cmd = "dbus-monitor --session \"type='signal',interface='org.freedesktop.ScreenSaver',member='ActiveChanged'\"";

my $interface = <DEFINE INTERFACE HERE>

open (IN, "$cmd |");

while (<IN>) {
if (m/^\s+boolean true/) {
    #when screensaver activates, run the following commands
    system("/sbin/ifdown $interface");
} elsif (m/^\s+boolean false/) {
    #when screensaver deactivates, run the following commands
    system("/sbin/ifup $interface");
}
}

save it as something memorable to /etc/rc.d

make it executable with chmod +x
