**d4-goclient** is a D4 project client (sensor) implementing the [D4 encapsulation protocol](https://github.com/D4-project/architecture/tree/master/format). The client can be used on different targets and architectures to collect network capture, logs, specific network monitoring and send it back to a [D4 server](https://github.com/D4-project/d4-core). For more information about the [D4 project](https://www.d4-project.org/). # Installation Fetch d4-goclient code and dependencies ```bash go get github.com/satori/go.uuid go get github.com/D4-project/d4-goclient ``` Use make to build binaries: ```bash make arm5l # for raspberry pi / linux make amd64l # for amd64 / linux ``` ## Dependencies - golang 1.10 (tested) - go.uuid # Use ## Launch a d4-server (if you don't have a server) See https://github.com/D4-project/d4-core/tree/master/server $IP_SRV being the d4-server's address, $PORT its listening port ## Pipe data into the client ### Some file ```bash cat /proc/cpuinfo | ./d4-goclient -c conf.sample/ | socat - OPENSSL-CONNECT:$IP_SRV:$PORT,verify=0 ``` ### tcpdump (libpcap) output, discarding our own traffic $IP being the monitoring computer ip ```bash tcpdump not dst $IP and not src $IP -w - | ./d4-goclient -c conf.sample/ | socat - OPENSSL-CONNECT:$IP_SRV:$PORT,verify=0 ```
