Mac Osx Tool For Watching Network Trafic

Posted on  by 

Activity Monitor. A free solution for tracking bandwidth usage comes in the form of Activity Monitor. Bundled with OS X by default, this app has a small “Network” tab at the bottom which will show a few useful statistics about your connection. Network tools that simulate slow network connection [closed]. So it works great on OSX (haven't tried it on Windows or Linux yet) - easy to install & run, works.

Monitoring your network can be a real pain. First and foremost, what tool should you use? Everyone you ask will give you a different answer. Each answer will reflect a different set of requirements and, in some cases, fill completely different needs. Here are the five network monitors I prefer, based on two criteria: They're free (as in cost) and easy to use. You might not agree with the choices, but at the price point, you'd be hard pressed to find better solutions.

1: Wireshark

Wireshark (Figure A) has always been my go-to monitor. When most other monitors fail to find what I want, Wireshark doesn't let me down. Wireshark is a cross-platform analyzer that does deep inspection of hundreds of protocols. It does live capture and capture save (for offline browsing), which can be viewed in GUI or tty mode. Wireshark also does VoIP analysis and can read/write many capture formats (tcpdump, Pcap NG, Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, and many more).

2: Angry IP Scanner

Angry IP Scanner (Figure B) is one of the easiest to use of all the IP scanners. It has a user-friendly GUI that can scan IP addresses (and their ports) in any range. Angry IP Scanner is cross platform and doesn't require installation, so you can use it as a portable scanner. It can get NetBIOS information, favorite IP address range, Web server detection, customizable openers, and much more. This little scanner makes use of mutlithreads, so it's going to be fairly fast. Source code is available on the download page.

3: Zenmap

Zenmap (Figure C) is a graphical front end to the cross-platform Nmap tool. Nmap can scan huge networks, is portable, free, and well documented. It's one of the most powerful IP traffic monitors, but that power comes with a price: complexity. Zenmap takes Nmap and makes it more accessible to users who prefer to avoid the command line. That does not mean Zenmap is the easiest of the lot. You still need to use some commands. But Zenmap offers a powerful wizard-like tool to help you through the process.

4: Colasoft Capsa Free

If you're an admin used to more Windows-like tools, Capsa Free (Figure D) might be the perfect tool for you. There are actually two versions of Capsa: paid and free. The free version should be enough in most cases. It provides an easy-to-use dashboard you can use to create various types of captures. Capsa Free also offers plenty of alarm configurations so you can be alerted when something occurs. And it can capture more than 300 network protocols, so you won't be missing out on anything with this free tool.

5: EtherApe

EtherApe is a Linux-only tool and is molded after the classic etherman monitor. It's unique in that it offers an easy-to-use mapping of IP traffic on your network. It does this in real time and gives you a clear picture of the overall look of your network traffic. You can create filters (using pcap syntax) to make reading the map easier. As you can see in Figure E, a busy network can get rather challenging to read. EtherApe will display both the node and link color with the most-used protocol so it's easier to take a quick glance, even on a busy network.Watching

More tools?

A lot of networking monitoring tools are out there, and some of them do more auditing than the tools listed here. But when you really need to know what's going on with your network, one of the above tools will do a great job.

Have you used any of these tools? What other free scanners have you tried?

What's the best tool that you use to monitor Web Service, SOAP, WCF, etc. traffic that's coming and going on the wire? I have seen some tools that made with Java but they seem to be a little crappy. What I want is a tool that sits in the middle as a proxy and does port redirection (which should have configurable listen/redirect ports). Are there any tools work on Windows to do this?

For Windows HTTP, you can't beat Fiddler. You can use it as a reverse proxy for port-forwarding on a web server. It doesn't necessarily need IE, either. It can use other clients.

Wireshark does not do port redirection, but sniffs and interprets a lot of protocols.

You might find Microsoft Network Monitor helpful if you're on Windows.

Wireshark (or Tshark) is probably the defacto standard traffic inspection tool. It is unobtrusive and works without fiddling with port redirecting and proxying. It is very generic, though, as does not (AFAIK) provide any tooling specifically to monitor web service traffic - it's all tcp/ip and http.

The third, “Lost Partition Recovery”, recovers lost data from lost or deleted partitions, subject to success in finding them. The first, “Undelete Recovery”, can be used to quickly recover data lost due to accidental deletion. Data recovery tool for mac. The second, “Damaged Partition Recovery”, recovers lost data from existing partitions.

You have probably already looked at tcpmon but I don't know of any other tool that does the sit-in-between thing.

I tried Fiddler with its reverse proxy ability which is mentioned by @marxidad and it seems to be working fine, since Fiddler is a familiar UI for me and has the ability to show request/responses in various formats (i.e. Raw, XML, Hex), I accept it as an answer to this question. One thing though. I use WCF and I got the following exception with reverse proxy thing:

The message with To 'http://localhost:8000/path/to/service' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree

I have figured out (thanks Google, erm. I mean Live Search :p) that this is because my endpoint addresses on server and client differs by port number. If you get the same exception consult to the following MSDN forum message:

I second Wireshark. It is very powerful and versatile.And since this tool will work not only on Windows but also on Linux or Mac OSX, investing your time to learn it (quite easy actually) makes sense. Whatever the platform or the language you use, it makes sense.

JMeter's built-in proxy may be used to record all HTTP request/response information.

Firefox 'Live HTTP headers' plugin may be used to see what is happening on the browser side when sending/receiving request.

Firefox 'Tamper data' plugin may be useful when you need to intercept and modify request.
