Other parameters allow you to use a custom configuration URL for testing, produce computer-readable output, or show help information.
#NETWORK SNIFFER MAC DOWNLOAD#
Using the -s switch, networkQuality will run its download and upload tests sequentially, instead of in parallel. On my Mac, for example, networkQuality -I en1 would direct the utility to test my WiFi adapter instead of Ethernet.
If you have multiple network interfaces, you can specify which to use with the -I switch. Using the -v switch, networkQuality provides more information in the summary than the test does by default I did see these values earlier in the network sniffer. Just type man networkQuality, and you’ll get the “help” file for the executable. When I search something like 'alpha' in the omnibar of the Chrome browser, I would like to see values of two parameters qalpha and oit1. As with most command-line executables, you can get that information using the man command. The test has more capabilities, once you learn the command-line switches. // For sniffing the socket to capture the packets // has to be a raw socket, with the address family // being of type internetwork, and protocol being IP mainSocket newSocket (AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.IP) // Bind the socket to the selected IP address mainSocket.Bind (newIPEndPoint (IPAddress. High: Regardless of the number of devices and apps sharing the network, apps and services should maintain good connection. Medium: When multiple devices or apps are sharing the network, you might see momentary pauses or freezes, like during FaceTime audio or video calls.
#NETWORK SNIFFER MAC MOVIE#
Low: If any device on the same network is, for example, downloading a movie or backing up photos to iCloud, the connection in some apps or services might be unreliable, like during FaceTime video calls or gaming. This is measuring Round-trips Per Minute (RPM), or how many transactions your network can complete in one minute.Īccording to Apple’s support document for the test, here’s what each classification means. The responsiveness of your network is reported as Low, Medium, or High. It also reported the number of upload and download flows it used, along with a responsiveness classification. The output of macOS Monterey’s networkQuality testĪt the end, a summary provided my average upload and download speeds during the testing. Most speed tests measure your downstream and upstream separately, which doesn’t help you understand issues you might have with video chat or voice calls. It’s important to note that the macOS test is running upload and download measurements in parallel, not sequentially. Within a few seconds, I was already seeing the results: real-time measurement of my upload and download speeds. During my testing, the command ran for an average of 15 seconds.
