Net-up

A program using google-gopacket to set BPF filter and analyse packets at a configured network devise

Requirement

1. golang

Set-up

1. go get the project
2. Set the network devise to start intercepting with BPF

    export NET_FILTER="tcp and port 3000" 
    export NET_LOGLEVEL=debug 
    export NET_NETWORKDEVISE=lo0
    export NET_OUTPUT=stdout 
   

3. Run the executable with sudo access.

   sudo ./net-up
   

Currently the program just outputs the packet details to stdout, ie NET_OUTPUT supports stdout. It needs to be extended to support writing to file, etc.
