7. Network Services: Lesson Twenty-four Flashcards
Which sharing services can OS X provide?
The OS X sharing services include: • DVD or CD sharing • Screen Sharing • File Sharing • Printer Sharing • Scanner Sharing • Remote Login (SSH) • Remote Management (ARD) • Apple Events • Internet Sharing • Bluetooth Sharing
What’s the security risk of enabling client sharing services?
If a client sharing service is compromised, an unauthorized user can control your Mac and execute unwanted apps or processes.
Which app can provide on-demand screen sharing even when the Screen Sharing service isn’t enabled?
Messages provides on-demand screen sharing that you can use when the system screen sharing service isn’t enabled.
What’s AirDrop, and how do you know if a specific Mac supports it?
AirDrop provides a quick and easy way to share files locally via Wi-Fi.
AirDrop creates a secure peer-to-peer network between local devices.
You can verify that a Mac supports AirDrop from the Finder Go menu.
Assuming you have a brand-new Mac with OS X El Capitan installed, what other devices will appear in the AirDrop browser with the default settings?
When you open the AirDrop browser on a late-model Mac with OS X, the browser shows only other late-model Mac computers with OS X, and late-model iOS devices with iOS 7 or later.
If other devices with AirDrop enabled aren’t appearing in the AirDrop browser, which two settings on a Mac can you change to potentially make more devices appear?
On a late model-Mac, you’ll find two settings at the bottom of the AirDrop browser that control AirDrop discovery.
The first setting expands AirDrop discovery from only users in your Contacts to everyone within AirDrop range.
The second setting makes AirDrop revert to the previous discovery method, which allows your Mac to discover older Mac computers and Mac computers running previous versions of OS X.
In what primary way does the OS X built-in firewall differ from a traditional network firewall?
With the firewall built into OS X, connections are allowed or denied on a per-app basis. This is unlike traditional network firewalls, where access rules are based on network service port numbers.
Which optional firewall settings are available?
The optional firewall settings enable you to control whether signed apps are automatically allowed through the firewall, control the list of allowed (or denied) apps, and enable stealth mode (which means your Mac won’t respond to any unsolicited connections).
