This is senior editor Dan Moren. We take networking for granted these days, but it's still a complicated beast. If you want to go under the hood, Apple includes a suite of tools on your Mac to help you troubleshoot networking issues; they're all included in the Network Utility app, which you can find in System/Library/CoreServices/Applications—though it's probably easier to simply type 'Network Utility' into Spotlight.
When you first launch Network Utility, you'll see a single window with a variety of tabs, each of which offers different information. The first tab, Info, provides information about your own computer, offering a drop-down menu of all your network interfaces—for example, if you have both wired ethernet and Wi-Fi connections. When you select one, you'll see the Hardware Address, associated IP, speed, and information about how much data is going in and out of that particular connection. Most often you'll refer to the info here when troubleshooting issues.
Next, we'll take a look at the Ping tab. This tool sends packets of data over the network to a specified address, which can help you figure out if the remote server in question is encountering problems. To check if there are issues on your local network, you can ping your router's address, which you can find in the Network preference pane. By default, ping sends 10 packets, and then reports how many of those packets successfully arrived at the destination and how long it took those packets to make the trip. If you're losing a lot of packets, or they take a long time to arrive, it's a good indication that there's a network slowdown. If you're getting errors about all your packets, there's probably a network problem on your own side.
The Lookup tool is a handy one if you've ever had questions about just where an IP address comes from. Think of it like a phone book: Enter any domain name to get the corresponding IP address (or vice versa). On the off chance that you find yourself poring over network logs or wondering about where an email came from, this tool might provide some illumination.
My first major unity project. Machine at the heart of the world mac os. I have to say that despite it being very basic, I am still very proud of it. Special thanks to Ben Tristem and the GameDev.tv team for putting together an. Basic terminal commands are not listed here. Some of them are listed in the following Terminal command articles. Terminal Commands – Basic Terminal Commands – Part 2 Terminal Commands – Part 3. Many of the commands have also been used in the article I wrote some time back. You can have a look at the scripts to see some of the commands.
If you've ever wanted to feel like your typical movie hacker, the Traceroute tab might scratch that itch. Think of it as a more detailed version of the ping tool—not only does it send packets to a specified server, but it also charts all the stops that packet makes. (It's a bit like tracking a train's route.) If there's a particular server in the chain that's slowing your connection down, this can help you suss it out—though doing something about that is probably out of your reach; you may wish to talk to your ISP.

Finally, the Whois tool is the place to go if you're wondering who owns a particular domain name. Just enter the domain name and scroll down to find a full listing about its owner—though be aware many registrars these days offer tools to anonymize domain name listings, so you may not find exactly what you're looking for.
Network Utility has a few additional tools that can be handy for networking troubleshooting, but they require a bit more in the way of know-how. Still, you should feel free to play around with them and see what you can learn. This is senior editor Dan Moren. Thanks for watching.
One sign of OS X's overall security savvy is that it has its own built-in firewall, which is pretty good. But there are many other firewall add-on apps for the Mac, including Brian Hill's Flying Buttress 1.4, Intego's NetBarrier X4, Open Door Networks' DoorStop X Security Suite, SustainableSoftworks' IPNetSentryX 1.3.1, and Symantec's Norton Personal Firewall 3.0.3 (see table below below for details).
Guarding the gates
How safe will these apps keep your Mac? In blocking traffic, the differences between these products are razor-thin. They all block bad network traffic and protect your Mac just as they should. But there are two areas where a couple of these apps fall short.
Hackers looking for a computer to exploit may ping yours to see if it'll reply; if it does, the answer lets them know what operating system your computer is running—an excellent starting point for their nefarious games. In our testing, Apple's built-in firewall, Flying Buttress, and Norton all spilled the beans about which OS our test system used.
The other hole we found in some of these tools is that basic firewalls simply allow or block traffic passing through your network ports. But some programs offer another level of protection—intrusion detection. They examine incoming traffic to see whether it's doing anything unusual and warn you if they detect anything suspicious. Prison (mightycrazyfoo) mac os. IPNetSentryX and NetBarrier are the only programs we looked at that have intrusion-detection tools.
While these programs are similarly skilled in protecting your Mac, they differ in ease of use. While each one lets you specify which network ports you want to block or leave open, NetBarrier and Norton make it particularly simple; IPNetSentryX, on the other hand, requires some advanced network knowledge to set up properly.
And each of these apps provides some kind of reporting system, from basic text documents that log access attempts to e-mailed notifications.
Firewall software compared
| Company | Product (full review) | Rating | Price | Pros | Cons |
|---|---|---|---|---|---|
| Apple | Mac OS X Firewall | free (A) | Already part of Mac OS; stealth mode and logging tools; can block UDP traffic. | Advanced configuration requires Terminal; reveals OS; logs could confuse network newbies | |
| Brian Hill | Flying Buttress 1.4 | $25 | Excellent front end to OS X's built-in firewall; GUI access to features otherwise available through Terminal; syntax checker. | Limited support; poor documentation; some configuration requires advanced knowledge; reveals OS. | |
| Intego | NetBarrier X4 | $70 | Intrusion detection; anti-spyware tools; cookie management; monitoring tools; simple setup. | Default configurations are either too permissive or too restrictive; customized configuration requires some knowledge of network security. | |
| Open Door Networks | DoorStop X Security Suite | $80 | Excellent documentation; provides detailed information about logs and security instruction; excellent support. | Default settings too stringent; doesn't warn against accidentally locking down services that you might need. | |
| Sustainable Softworks | IPNetSentry X 1.3.1 | $60 | Intrusion detection; highly configurable; excellent logging and bandwidth utilization controls. | Requires significant technical knowledge to manage correctly. | |
| Symantec | Norton Personal Firewall 3.0.3 | $50 | Simple setup and configuration; recognizes applications that require network access; easy to add new port or service security. | Stealth mode reveals OS. |

Macworld's buying advice
When it comes to keeping snoops out of your Mac, OS X's firewall is all most users really need. It's safe, secure, and free. But its interface is awfully basic; for any advanced configuration, you'll have to head to Terminal.

Intego's NetBarrier X4 gets our nod as the best OS X firewall, thanks to its ease of configuration, boatload of useful features, and excellent documentation. Norton Personal Firewall and DoorStop X Security Suite are also excellent options but offer fewer features. I personally like (and use) Flying Buttress. But its lack of consistent support and its limited documentation make it a poor choice for the average user.
IPNetSentryX is in a class all its own. It's an intrusion-detection program that's really designed for network professionals who know what to look for on their networks and who have a thorough knowledge of TCP, UDP, and IP. If you're wondering what I'm talking about, IPNetSentryX is not for you. But if you've just begun to salivate, it will be a powerful addition to your network security toolbox.
