The amount of resources Wireshark needs depends on your environment and on the size of the capture file you are analyzing. The values below should be fine for small to medium-sized capture files no more than a few hundred MB. Larger capture files will require more memory and disk space.
|Busy networks mean large captures|
A busy network can produce huge capture files. Capturing on even a 100 megabit network can produce hundreds of megabytes of capture data in a short time. A computer with a fast processor, and lots of memory and disk space is always a good idea.
If Wireshark runs out of memory it will crash. See https://gitlab.com/wireshark/wireshark/wikis/KnownBugs/OutOfMemory for details and workarounds.
Although Wireshark uses a separate process to capture packets, the packet analysis is single-threaded and won’t benefit much from multi-core systems.
Wireshark should support any version of Windows that is still within its extended support lifetime. At the time of writing this includes Windows 10, 8.1, Server 2019, Server 2016, Server 2012 R2, and Server 2012. It also requires the following:
A supported network card for capturing
Older versions of Windows which are outside Microsoft’s extended lifecycle support window are no longer supported. It is often difficult or impossible to support these systems due to circumstances beyond our control, such as third party libraries on which we depend or due to necessary features that are only present in newer versions of Windows such as hardened security or memory management.
See the Wireshark release lifecycle page for more details.
Wireshark supports macOS 10.13 and later. Similar to Windows, supported macOS versions depend on third party libraries and on Apple’s requirements.
The system requirements should be comparable to the specifications listed above for Windows.
Wireshark runs on most UNIX and UNIX-like platforms including Linux and most BSD variants. The system requirements should be comparable to the specifications listed above for Windows.
Binary packages are available for most Unices and Linux distributions including the following platforms:
If a binary package is not available for your platform you can download the source and try to build it. Please report your experiences to wireshark-dev[AT]wireshark.org.
