Windows pktmon equivalent in Linux
Captures packets from network interfaces for troubleshooting and protocol analysis.
pktmon
sudo tcpdump -i any
sudo tcpdump -i any
sudo tcpdump -i any
Overview
What this command does
On Windows, "pktmon" is used to capture network packets. On Linux, the closest practical mapping shown here is "sudo tcpdump -i any". Captures packets from network interfaces for troubleshooting and protocol analysis. This reference is grouped under Networking.
Windows → Linux context
What changes when you use this on Linux?
Equivalent task, different tool
Windows pktmon maps to sudo tcpdump -i any for this task. Treat this as a workflow mapping rather than a character-for-character syntax translation.
Portable across the compared distros
The Debian/Ubuntu, Fedora and Arch rows use the same command in this mapping. Package availability or defaults can still vary, so check the installed tool version when an option behaves differently.
Elevated privilege appears in this workflow
At least one example uses sudo. Confirm the target path, device, service or package before running the elevated form; do not add sudo simply to bypass an unexplained permission error.
Command-specific caution
Packet captures can contain credentials and private data. Protect capture files and capture only networks you are authorized to inspect.
For the broader concept behind this mapping, read Linux networking for Windows users.

Walkthrough
Examples with explanations
sudo tcpdump -i any # capture all visible traffic
sudo tcpdump -i enp5s0 port 53 # capture DNS packets only
sudo tcpdump -i any -w capture.pcap # save a capture for later analysisReference
Common options and variations
