  # I submitted this patch to the upstream author, Oreste Notelli, on
  # 2011-12-22, so this patch will probably not be necessary with future
  # justniffer versions after 0.5.11.

    Sample invocation to get you started:
      justniffer -i en1 -p "port 80"

    "en1" is my wireless inteface; "en0" is Ethernet; see output of ifconfig
