/ 19 марта 2019

Я создаю приложение vpn mac и приложение iOS, когда пытаюсь подключиться, получая The VPN server did not respond. Verify the server address and try reconnecting., но когда я пытаюсь вручную в системных настройках установить соединение,

это учетные данные

адрес сервера: 45.32.23.55

имя пользователя: vpn

пароль: vpn

sharedsecret: vpn 


    func vpnLoader() {

        vpnManager.loadFromPreferences { error in
            // setup the config:
        let p = NEVPNProtocolIPSec()
        p.username = "vpn"
        p.serverAddress =  "45.32.23.55"
        p.remoteIdentifier = "45.32.23.55"
        p.localIdentifier = "192.168.xx.xxx"
        p.authenticationMethod = .sharedSecret
            do {

                p.sharedSecretReference = try VPNKeychain.persistentReferenceFor(service: "45.32.23.55", account: "vpn", password: ("vpn").data(using: String.Encoding.utf8, allowLossyConversion: false)!)
                p.passwordReference = try VPNKeychain.persistentReferenceFor(service: "45.32.23.55", account: "vpn", password: ("vpn").data(using: String.Encoding.utf8, allowLossyConversion: false)!)
            } catch let error {
                print(error)
            }

        p.useExtendedAuthentication = true
        p.disconnectOnSleep = false
        self.vpnManager.protocolConfiguration = p
        self.vpnManager.localizedDescription = "secure_VPN"
        self.vpnManager.isEnabled = true
        self.vpnManager.isOnDemandEnabled = true
            print("saving")
            assert(self.vpnManager.isEnabled)

            self.vpnManager.saveToPreferences { error in
                guard error == nil else {
                    print("NEVPNManager.saveToPreferencesWithCompletionHandler failed: \(error!.localizedDescription)")
                    return
                }
          do {
                try self.vpnManager.connection.startVPNTunnel()

            } catch let error {
                print("Error starting VPN Connection \(error.localizedDescription)");
            }

            }
        }
//        self.vpnManager.saveToPreferences(completionHandler: self.vpnSaveHandler)

    }

используя приведенный выше код, я сохраняю настройки икод ниже для сохранения и получения ссылки на пароль и общей секретной ссылки из цепочки для ключей.
