The traceroute mac command output shows the Layer 2 path when the specified source and destination addresses belong to the same VLAN. If you specify source and destination addresses that belong to. Performing a Traceroute in Mac OS X. If you are running Mac® OS X, you can use the Network Utility application, which is included with Mac OS X, to run the trace route. Launch Network Utility. Note: You can do this through Mac OS X Spotlight by typing Network Utility, and then clicking the Top Hit.

Whether you’re using Windows, Linux, or Mac OS X, these tools are always close at hand. You’ll also find web-based versions of many of these utilities. Some are even available in Chrome OS’s hidden Crosh shell.

ping

RELATED:How To Troubleshoot Internet Connection Problems

The ping command sends ICMP echo request packets to a destination. For example, you could run ping google.com or ping 173.194.33.174 to ping a domain name or IP address.

These packets ask the remote destination to reply. If the remote destination is configured to reply, it will respond with packets of its own. You’ll be able to see how long the round-trip time is between your computer and the destination. You’ll see a “request timed out” message if packet loss is occurring, and you’ll see an error message if your computer can’t communicate with the remote host at all.

This tool can help you troubleshoot Internet connection problems, but bear in mind that many servers and devices are configured not to reply to pings.

traceroute / tracert / tracepath

RELATED:How to Use Traceroute to Identify Network Problems

The traceroute, tracert, or tracepath command is similar to ping, but provides information about the path a packet takes. traceroute sends packets to a destination, asking each Internet router along the way to reply when it passes on the packet. This will show you the path packets take when you send them between your location and a destination.

This tool can help troubleshoot connection problems. For example, if you can’t communicate with a server, running traceroute may show you where the problem is occurring between your computer and the remote host.

ipconfig / ifconfig

The ipconfig command is used on Windows, while the ifconfig command is used on Linux, Mac OS X, and other Unix-like operating systems. These commands allow you to configure your network interfaces and view information about them.

For example, you can use the ipconfig /all command on Windows to view all your configured network interfaces, their IP addresses, DNS servers, and other information. Or, you can use the ipconfig /flushdns command to flush your DNS cache, forcing Windows to get new addresses from its DNS servers every time you contact a new hostname. Other commands can force your computer to release its IP address and get a new one from its DHCP server. This utility can quickly display your computer’s IP address or help you troubleshoot problems.

nslookup

RELATED:What Is DNS, and Should I Use Another DNS Server?

The nslookup command will look up the IP addresses associated with a domain name. For example, you can run nslookup howtogeek.com to see the IP address of How-To Geek’s server.

Mac Traceroute Command

Your computer is constantly querying its DNS servers to translate domain names to IP addresses. This command just allows you to do it manually.

nslookup also allows you to perform a reverse lookup to find the domain name associated with an IP address. For example, nslookup 208.43.115.82 will show you that this IP address is associated with howtogeek.com.

whois

The whois command looks up the registration record associated with a domain name. This can show you more information about who registered and owns a domain name, including their contact information.

This command isn’t included with Windows itself, but Microsoft’s Windows Sysinternals provides a Whois tool you can download. This information is also available from many websites that can perform whois lookups for you.

netstat

netstat stands for network statistics. This command displays incoming and outgoing network connections as well as other network information. It’s available on Windows, Mac, and Linux — each version has its own command-line options you can tweak to see different types of information.

The netstat utility can show you the open connections on your computer, which programs are making which connections, how much data is being transmitted, and other information.

finger

The finger command is old and is no longer widely used. In theory, this command allows you to view information about users logged onto a remote computer. If the computer is running a finger service or daemon, you can use the finger command on your computer to see who’s logged in on that remote computer, their email address, and their full name. In practice, almost no computers are running a finger service you can connect to.

This utility was a cute idea in the early days of networking where you might want to see who was logged into the other few computers on your university network, but it’s not suitable for a dangerous internet. You don’t want people to see your full name and email address when you’re using a computer.

Still, the finger command lives on as a common network utility and is even still included in modern versions of Windows. Windows doesn’t include a finger service that can share this information with others, though.

Port Scan / nmap

The nmap utility is a common tool used for port scans, but there are many utilities that can run this sort of scan. A port scan is the process of attempting to connect to every port on a computer — ports 1 through 65535 — and seeing if they’re open. An attacker might port-scan a system to find vulnerable services. Or, you might port scan your own computer to ensure that there are no vulnerable services listening to the network.

These aren’t the only network-related commands, but they are some of the most common.

How Traceroute Works

When you connect to a website – say, howtogeek.com – the traffic has to go through several intermediaries before reaching the website. The traffic goes through your local router, your Internet service provider’s routers, onto larger networks, and so on.

Traceroute shows us the path traffic takes to reach the website. It also displays the delays that occur at each stop. If you’re having issues reaching a website and that website is working properly, it’s possible there’s a problem somewhere on the path between your computer and the website’s servers. Traceroute would show you where that problem is.

Traceroute Tool For Windows

We’ve used traceroute to explain – and demonstrate — who provides the Internet service for your Internet service provider.

In more technical terms, traceroute sends a sequence of packets using the ICMP protocol (the same protocol used for the ping command.) The first packet has a time-to-live (also known as TTL, or hop limit) of 1, the second packet has a TTL of 2, and so on. Each time a packet is passed to a new router, the TTL is decreased by 1. When it reaches 0, the packet is discarded and the router returns an error message. By sending packets in this manner, traceroute ensures that each router in the path will discard a packet and send a response.

How to Use Traceroute

Traceroute Mac Os

Traceroute is run from a command prompt or terminal window. On Windows, press the Windows key, type Command Prompt, and press Enter to launch one.

Os X Traceroute

To run a traceroute, run the tracert command followed by the address of a website. For example, if you wanted to run a traceroute on How-To Geek, you’d run the command:

tracert howtogeek.com

(On Mac or Linux, run traceroute howtogeek.com instead.)

You’ll gradually see the route take form as your computer receives responses from the routers along the way.

If you run a traceroute for another website – particularly one hosted in a different region of the world – you’d see how the paths differ. The first “hops” are the same as the traffic reaches your ISP, while the later hops are different as the packets go elsewhere. For example, below you can see the packets travelling to Baidu.com in China.

Understanding the Output

The basic idea is self-explanatory. The first line represents your home router (assuming you’re behind a router), the next lines represent your ISP, and each line further down represents a router that’s further away.

The format of each line is as follows:

Traceroute App Mac Os

Hop RTT1 RTT2 RTT3 Domain Name [IP Address]

Hop: Whenever a packet is passed between a router, this is referred to as a “hop.” For example, in the output above, we can see that it takes 14 hops to reach How-To Geek’s servers from my current location.
RTT1, RTT2, RTT3: This is the round-trip time that it takes for a packet to get to a hop and back to your computer (in milliseconds). This is often referred to as latency, and is the same number you see when using ping. Traceroute sends three packets to each hop and displays each time, so you have some idea of how consistent (or inconsistent) the latency is. If you see a * in some columns, you didn’t receive a response – which could indicate packet loss.
Domain Name [IP Address]: The domain name, if available, can often help you see the location of a router. If this isn’t available, only the IP address of the router is displayed.

You should now be able to use the tracert command and understand its output.
