Remote tcpdump stream to wireshark

Archived from https://twitter.com/ElijahLynn/status/1144399526452588545

Just had to debug yum returning a 503 on a server deep in a private network, but curl worked fine. Was able to use tshark and pipe it to my local wireshark and re-assemble the HTTP request that finally told me it was blocked by the internet gateway and who to email!

Here is the command that piped in realtime the tshark dump to my local wireshark GUI. Don't worry about the CLI filter because we can just use display filters to get what we want. Then find a GET packet, right click and "Follow" > TCP||HTTP Stream

Amazing!

Would help if I pasted the command!
