Tool 89: TCP server
  
  Description:
   
  This tool listens on a TCP port. Use tool 87 to connect to it.
  
  Parameter --src-port defines the local port number to listen on.
  Optional parameter --src-ip defines the local IP address to use.
  Optional parameter --iptype defines which kind of IP address to use
  when --src-ip is unset (accepted values: ip4 and ip6).
  Optional parameter --ip4opts permits to add IP4 options encoded as
  mixed.
  Optional parameter --ip6exts permits to add IP6 options encoded as
  mixed (first byte is the next header number).
  Optional parameters --device and --src-eth permits to create
  a virtual server using fake addresses (in this case, tool have to be
  run with admin privilege in order to sniff and spoof at Ethernet
  level).
  Parameter --encode defines how to display data (common values: data,
  dump, mixed).
  Parameter --decode defines how keyboard data is entered (common
  values: data, mixed).
