### Tool 44: Spoof of packet samples : fragment, ip4opt:rr

### Description:

      This tool sends hardcoded packet samples. Samples are (--sample
      defines number): 1=udp_syslog, 2=tcp_syn, 3=tcpsynack, 4=tcpack,
      5=ping.
      Packets contain IP4 options and can be fragmented before been sent.
      IP4 options contains a Record Route option.
      Parameter --spoofip indicates how to generate link layer for spoofing.
      Values 'best', 'link' or 'raw' are common choices for --spoofip. Here
      is the list of accepted values:
       - 'raw' means to spoof at IP4/IP6 level (it uses system IP stack). If
         a firewall is installed, or on some systems, this might not work.
       - 'linkf' means to spoof at link level (currently, only Ethernet is
         supported). The 'f' means to Fill source Ethernet address.
         However, if source IP address is spoofed, it might be impossible
         to Fill it. So, linkf will not work: use linkb or linkfb instead.
       - 'linkb' means to spoof at link level. The 'b' means to left a Blank
         source Ethernet address (0:0:0:0:0:0, do not try to Fill it).
       - 'linkfb' means to spoof at link level. The 'f' means to try to Fill
         source Ethernet address, but if it is not possible, it is left
         Blank.
       - 'rawlinkf' means to try 'raw', then try 'linkf'
       - 'rawlinkb' means to try 'raw', then try 'linkb'
       - 'rawlinkfb' means to try 'raw', then try 'linkfb'
       - 'linkfraw' means to try 'linkf', then try 'raw'
       - 'linkbraw' means to try 'linkb', then try 'raw'
       - 'linkfbraw' means to try 'linkfb', then try 'raw'
       - 'link' is an alias for 'linkfb'
       - 'rawlink' is an alias for 'rawlinkfb'
       - 'linkraw' is an alias for 'linkfbraw'
       - 'best' is an alias for 'linkraw'. It should work in all cases.

      This tool may need to be run with admin privilege in order to spoof.
