Hi, I am new to network extension programming. I have one 'cpp' application which will run under /usr/local/sample directory. I want to listen all UDP & TCP network operation using network extension Content Filter in my c++ application, and I want execute my own rules on received event. Is it possible to register network extensions from my 'cpp' application and Is it possible to catch the events on TCP & UDP using network extension from my c++ application? How it would be possible? Please provide any sample program.

Hi, I am new to network applications. Should place network extension application in /Applications to run it? or Is network extension application run from any where on the machine?

Hi, I am new to network extensions. Is there any sample program for network extension content filters in Objective-c? I have found in swift but not find in Objective-C. I want to register network extensions and I want listen all TCP & UDP network operations using network extension content filters in Objective-C.

Hi, I am new to Swift language. I am trying to convert below C++ function to Swift function as below.

Could any one please to convert this. Error due to first argument mib: Cannot convert value of type '[Int]' to expected argument type 'UnsafeMutablePointer<Int32>?'

Hi, I want to activate/deactivate network extension on Mac without any user consent (I want allow network extension activation/deactivation on Mac by default) and Mac is under un-managed environment (Not managed by MDM tools).

It can be possible with system() on C++ as system("systemextensionsctl list | grep FilterExtension | grep activated") But how can I achieve this in swift language? Help me. Thanks.

Hi, I am using file provide extension to sync the app with remote storage. createItem() fileprovideer extension is calling when I copy a file and I able to sync properly with normal file and symlink files. itemTemplate.symlinkTargetPath helps me to sync symlink file. But, I am facing the with alias file to sync. I tried to get original file name of alias file but I haven't found any option. How to get the original file name of alias file at createItem() of fileprovider extension. Is there any way to sync alias file? My createItem() sample code at extension which sends the call to server through grpc. public func createItem( basedOn itemTemplate: NSFileProviderItem, fields: NSFileProviderItemFields, contents contentsUrl: URL?, options: NSFileProviderCreateItemOptions = [], request: NSFileProviderRequest, progress: Progress ) async throws -> (NSFileProviderItem, NSFileProviderItemFields) { var (templateAttributes, _) = self.load(fields: fields, from: itemTemplate) templateAttributes.ownerAccountID = getuid(); templateAttributes.groupOwnerAccountID = getgid(); let identifier: NSFileProviderItemIdentifier let attributes: FileProviderItemAttributes if itemTemplate.contentType?.conforms(to: .directory) == true { // Handle folder creation ..... ..... } else if itemTemplate.contentType?.conforms(to: .symbolicLink) == true { // Handle symlinks guard let targetPath = itemTemplate.symlinkTargetPath else { fatalError("couldn't get symlinkTargetPath on \(itemTemplate)") } .... .... } else if itemTemplate.contentType?.conforms(to: .aliasFile) == true { // TODO I am not yet handled this case. I need to get original path of alias file. } else { // Handle file creation .... .... } let item = try FileSystemItem.any(filename: itemTemplate.filename, identifier: identifier, parentIdentifier: itemTemplate.parentItemIdentifier, attributes: attributes) return (item, []) }

My customer installed two different apps on his Mac machine. These two apps are using ContentFilter extensions. One of the app is mine and another app is different vendor. If my customer enabled both ContentFilter extensions then he fails to connect immediately to its required destination to allow it to run. If one of the ContentFilter extension is disabled then there is no issue. Is it not possible to run two different ContentFilter extensions on same Mac machine? Is there any way to fix these type of issues? Thank You Nagendra R
