### Tool 176: TFTP client : get a file and check its MD5

### Description:

      This tool downloads a TFTP file and check its MD5.
      It ensures the server is working properly.

      Parameter --md5 is the expected md5sum.
      Parameter --dst-ip is the address of remote host/server.
      Parameter --dst-port is the port number where to connect.
      Optional parameter --src-ip defines the local IP address to use.
      Optional parameter --src-port defines the local port number to use.
      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, --src-eth and --dst-eth permits to
      create a virtual client using fake addresses (in this case, tool have
      to be run with admin privilege in order to sniff and spoof at
      Ethernet level).

### Usage:

netwox 176 -i ip -F file -s md5 [-d device] [-E eth] [-e eth] [-I ip] [-P port] [-p port] [-o ip4opts] [-O ip6exts] [-m data] [-T uint32] [-R uint32]
