Re: Switching Airport of in code using SCF

Thanks Allan that seemed to get the setting applied in the system config but Airport remains up after I run the tool and only comes down after a reboot. Is there any way I can force the interface down? I tried SCNetworkInterfaceForceConfigurationRefresh at the end of the code but that didn't work.

gPrefsRef = SCPreferencesCreate(nil, CFSTR("InterfaceConfig2"), nil);

if (gPrefsRef == nil)

errorAndExit("InterfaceConfig failure: SCPreferencesCreate failed");

if (!SCPreferencesLock(gPrefsRef, YES))

errorAndExit("InterfaceConfig failure: SCPreferencesLock could not get a lock");

NSEnumerator *e = [(NSArray *)SCNetworkSetCopyServices(SCNetworkSetCopyCurrent(gPrefsRef)) objectEnumerator];

SCNetworkServiceRef service;

while (service = (SCNetworkServiceRef)[e nextObject]) {

interfaceRef = SCNetworkServiceGetInterface(service);

if (isInterfaceOfType(interfaceRef, kSCNetworkInterfaceTypeIEEE80211)) {

CFDictionaryRef dict = (CFMutableDictionaryRef)[NSMutableDictionary dictionaryWithObjectsAndKeys:(NSString *)kSCValNetAirPortJoinModeAutomatic,

(NSString *)kSCPropNetAirPortJoinMode,

[NSNumber numberWithInt:0],

(NSString *)kSCPropNetAirPortPowerEnabled, nil];

if (SCNetworkInterfaceSetConfiguration(interfaceRef, dict) == NO) {

syslog(LOG_LOCAL7 | LOG_ALERT, "InterfaceConfig failure: Could not set Airport interface settings");

}

if (SCPreferencesCommitChanges(gPrefsRef) == NO)

errorAndExit("InterfaceConfig failure: SCPreferencesCommitChanges failed");

if (SCPreferencesApplyChanges(gPrefsRef) == NO)

errorAndExit("InterfaceConfig failure: SCPreferencesApplyChanges failed");

SCPreferencesUnlock(gPrefsRef);

CFRelease(gPrefsRef);
