You’ll be asked two question during this stage of the install. The fprobe install will ask which interface to capture from; typically the default is eth0. For Collector address, respond with localhost:9001. You can opt for a different port but we’ll use 9001 later when configuring the listening component of Nfsen. During the mrtg install, when prompted to answer “Make /etc/mrtg.cfg owned by and readable only by root?" answer Yes.
