Help remembering a network application

I remember reading somewhere about a self hosted application that would work like a proxy. But not http/https like NPM but all the network traffic.

I may be misremembering but what caught my attention at the time was the possibility to log communication packets. It was months ago and I ended up forgetting about it.

My use case would be monitoring communication with a device I’m developing an app for.

tcpdump, wireshark can capture packets.

haproxy can be a proxy of many networking protocols

mitmproxy can help see encrypted traffic by acting as a literal man in the middle.

ssh with certain parameters can become a SOCKS5 proxy to encrypt and tunnel traffic out of a hostile network

Yeah. I think tcpdump/wireshark is the way to go.

If your use-case is monitoring packets, why not go for an app made for that, such as Wireshark?

Nginx can do that itself with TCP and UDP streams: docs.nginx.com/nginx/…/tcp-udp-load-balancer/

But if you want to analyze traffic, use Wireshark.

Lots of them, if you want something large and powerful you could set up security onion, mirror a port and it’ll capture everything plus graph and slice up things all over. Needs a fairly hefty box not to choke if it gets fed a lot though.

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

Fewer Letters More Letters
HTTP Hypertext Transfer Protocol, the Web
IP Internet Protocol
TCP Transmission Control Protocol, most often over IP
UDP User Datagram Protocol, for real-time communications
nginx Popular HTTP server
