### Tool 167: TFTP server

### Description:

      This tool is a TFTP server.

      Parameter --allowed-clients lists the IP addresses or hosts allowed
      to connect.
      Parameter --rootdir defines the root directory for put and get file
      operations (cannot exit this root jail).
      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).

      This tool may need to be run with admin privilege in order to listen
      on a small port number (port<1024).
