(written by me) pcap2curl, which is similar in style but instead converts a saved PCAP file with a HTTP request to a curl command line. However, if you know the TCP port used (see above), you can filter on that one. Here are two tools that can help you: h2c, HTTP headers to curl, which converts a HTTP request to a suitable curl command line. You cannot directly filter HTTP2 protocols while capturing. The - b option given creates a new capture file each hour. your users documents directory, and use the real IPs of the server sites. Show only the HTTP2 based traffic: http2 Capture Filter Replace pathtocapturefile with the location of where you want the captures to go, e.g.

Display FilterĪ complete list of HTTP2 display filter fields can be found in the display filter reference On the SampleCaptures page, there is also http2-16-ssl.pcapng containing a HTTP2 (draft 16) over SSL capture (with keys) and a link to a TLS 1.3 HTTP/2 capture. HTTP gets a red light, HTTPS with a certificate signed by a trusted authority gets. Sample of HTTP2 (draft-14) - Created with nghttp2, need to use Decode as HTTP2 Every browser would have a little picture of a traffic light in a common place, probably next to the URL bar. Http2-h2c.pcap - HTTP/2 via Upgrade: h2 mechanism ( curl -http2 -v /robots.txt /humans.txt)

Wireshark 2.4 - header decompression support now requires external nghttp2 package (true for official Windows/macOS builds).

Wireshark 2.0 - initial HPACK support (header decompression).

The well known TCP port for HTTP/2 traffic is 443 (and 80).

TCP: Typically, HTTP/2 uses TCP as its transport protocol.
