conndetect

Small utility to track connections via /proc/net/tcp.

This is the first, naive implementation that considers the direction of connection to always be REMOTE -> LOCAL (which is obviously not true). I'll extend it later to use the listening ports to identify in what direction the socket was opened.

Requirements

• Go 1.12+

Installation

go get github.com/kbence/conndetect

or

git clone https://github.com/kbence/conndetect.git
cd conndetect
go get .

How to run the application?

If you have installed it with go get (given you have $GOPATH/bin on your $PATH), just execute:

conndetect

Or you can also run it directly using go (from the root directory):

go run .

Running in Docker

First, build the docker image:

docker build -t conndetect .

Then run the container with the following command. Make sure to pass --network host to get access to all the network activity.

docker run -it --rm --network host conndetect
