We’re now able to collect a packet capture on Windows hosts without adding any additional tools. Execution is as simple as giving the exe the source and destination files./etl2pcapng.exe c:\temp\capture.etl c:\temp\capture.pcap Lucky for us there’s an easy conversion utility etl2pcapng. The only item you should need to adjust will be the capture (sleep) timer.īut wait, the request was for a pcap file. Automated packet capture without having to install Wireshark on the host. Netsh trace start capture=yes IPv4.Address=$env:HostIP tracefile=c:\temp\capture.etl Now putting the two together: $env:HostIP = ( We can grab the local IPv4 address and save it as a variable.
