tracetcp-go

Reimplementation of tracetcp (http://simulatedsimian.github.io/tracetcp.html) in Go.

Installation:

$ go get github.com/0xcafed00d/tracetcp-go/cmd/tracetcp

Installs tracetcp executable into $GOPATH/bin

Configuration:

As tracetcp uses raw sockets it needs to be run as root, using sudo. To avoid running as root, issue the following command:

sudo setcap cap_net_raw=ep tracetcp 

If tracetcp is rebuilt, setcap will need to be run again.

Usage:

➤ ./tracetcp www.news.com
