I'll provide both GUI and command line (where applicable) for getting a basic capture. InstructionsĪnd now the part you've been anxiously waiting for, the steps for each solution. The only one with special requirements is Message Analyzer as certain features (like remote capture) are only possible on Windows 8.1, Server 2012 R2 and newer operating systems. Be sure to enable it when you are doing port mirroring to allow a computer to capture all traffic on the port - not just the packets destined for its own MAC address. One item to note is regarding promiscuous mode. Each will let you create a trace, capture multiple NICs, and define capture rules (typically, please don't as you may filter out something important). When collecting a short-term, simple trace for a set amount of time, there is not much of a difference in capturing with any of the tools. As pointed out in the table, netsh traces can be opened with Netmon or MMA, but not Wireshark. Getting a trace that way is often beneficial to eliminate the overhead of the GUI showing data and refreshing in real-time. Another item to note is that "netsh trace" is a command-line tool and the other three each have command-line alternatives for network captures. In many environments where change control is strict and the necessary software hasn't already been installed, this often makes it the only option. It does require an elevated command prompt to run, but nothing beyond that. Right off the bat, it should become apparent from the above table that one of these options - netsh trace – has one benefit over the others as it is ready to go without any further installation. ***Network Monitor is currently the only supported tool to install on an Advanced Threat Analytics server. Network Monitor can capture a chained set of files, but will not overwrite old files and can only be done via command line. ![]() ![]() **Wireshark can capture X files of Y size and roll as needed. client and server) using a single client. *MMA gives you the ability to setup and collect captures from multiple systems (e.g. MMA (Netmon or Wireshark if saved in CAP format)Ībility to capture a rolling set of files** Netmon or MMA (MMA can save in CAP format) Wireshark, MMA or Netmon (when traced saved in tcpdump format) Microsoft Message Analyzer (MMA) (v 1.4 as of 6/13/16).Netsh Trace – built-in to operating system.Network Monitor 3.4 (Netmon) – (NOTE: Network Monitor is no longer under active development).The Optionsįirst, let's cover each of the tools that can be used to collect a network trace, in order from older to newer Please note that when reviewing traces, you can use one or more of these tools and aren't necessarily tied to what was used to collect the trace. While colleagues have created blogs on getting a trace with a single tool, I wanted to provide a location that someone can bookmark to be a single set of instructions for a number of solutions. There are many solutions you can use and choosing the right one often depends on the scenario. One thing I always run into with my customers is that they often don't know the best or easiest solution to get a network capture. ![]() With my networking background, I have spent years reviewing network captures.
