DESCRIPTION

       jumbo6 allows the assessment of IPv6 implementations with respect to attack vectors  based
       on  IPv6  jumbograms. It is part of the SI6 Networks' IPv6 Toolkit : a security assessment
       suite for the IPv6 protocols.

       This tool has only one mode of operation: active mode. In active mode, the tool sends IPv6
       jumbograms  to  the  specified  target,  and informs the user of any received ICMPv6 error
       messages (typically "ICMPv6 Parameter Problem" error messages).

OPTIONS

       jumbo6 takes its parameters as command-line options. Each of the options can be  specified
       with a short name (one character preceded with the hyphen character, as e.g. "-i") or with
       a long name (a string preceded with two hyphen characters, as e.g. "--interface").

       jumbo6 supports IPv6 Extension Headers, including the  IPv6  Fragmentation  Header,  which
       might be of use to circumvent layer-2 filtering and/or Network Intrusion Detection Systems
       (NIDS). However, IPv6  extension  headers  are  not  employed  by  default,  and  must  be
       explicitly enabled with the corresponding options.

       -i INTERFACE, --interface INTERFACE
              This  option  specifies  the  network  interface  that  the  tool  will use. If the
              destination address ("-d" option) is a link-local address, the  interface  must  be
              explicitly  specified. The interface may also be specified along with a destination
              address, with the "-d" option.

       -S SRC_LINK_ADDR, --src-link-address SRC_LINK_ADDR

              This option specifies the link-layer Source Address of the probe packets.  If  left
              unspecified,  the  link-layer  Source  Address  of  the  packets is set to the real
              link-layer address of the network interface.

       -D DST_LINK_ADDR, --dst-link-address DST_LINK_ADDR

              This option specifies the link-layer  Destination  Address  of  the  probe  packets
              (currently,  only  Ethernet  is  supported). By default, the link-layer Destination
              Address is automatically set to the link-layer address of the destination host (for
              on-link destinations) or to the link-layer address of the first-hop router.

       -s SRC_ADDR, --src-address SRC_ADDR

              This  option  specifies the IPv6 source address (or IPv6 prefix) to be used for the
              Source Address of the outgoing packets. If an IPv6 prefix is  specified,  the  IPv6
              Source Address of the outgoing packets will be randomized from that prefix.

       -d DST_ADDR, --dst-address DST_ADDR

              This  option specifies the IPv6 Destination Address of the target node. This option
              cannot be left unspecified.

       --hop-limit, -A

              This option specifies the Hop Limit to be used for the IPv6  packets.  By  default,
              the Hop Limit is randomized.

       -y SIZE, --frag-hdr SIZE

              This  option  specifies  that the resulting packet must be fragmented. The fragment
              size must be specified as an argument to this option.

       -u HDR_SIZE, --dst-opt-hdr HDR_SIZE

              This option specifies that a Destination Options header is to be  included  in  the
              resulting  packet.  The  extension  header size must be specified as an argument to
              this option (the header is  filled  with  padding  options).  Multiple  Destination
              Options headers may be specified by means of multiple "-u" options.

       -U HDR_SIZE, --dst-opt-u-hdr HDR_SIZE

              This  option  specifies  a  Destination  Options  header  to  be  included  in  the
              "unfragmentable part" of the resulting packet. The header size must be specified as
              an  argument  to  this option (the header is filled with padding options). Multiple
              Destination Options headers may be specified by means  of  multiple  "-U"  options.
              This  option  is  only  valid  if  the  "-y" option is specified (as the concept of
              "unfragmentable part" only makes sense when fragmentation is employed).

       -H HDR_SIZE, --hbh-opt-hdr HDR_SIZE

              This option specifies that a Hop-by-Hop Options header is to  be  included  in  the
              resulting  packet.  The header size must be specified as an argument to this option
              (the header is filled with padding options). Multiple  Hop-by-Hop  Options  headers
              may be specified by means of multiple "-H" options.

       --ipv6-length, -q

              This  option  specifies  the value that the "Total Length" field of the IPv6 header
              should be set to. If this option is left unspecified, the "Total Length"  field  is
              set to 0, as required by the IPv6 jumbograms specification.

       --jumbo-length, -Q

              This  option  specifies  the value to which the "Jumbo Payload Length" field of the
              Jumbo Payload option should be set. If this option is left unspecified, the  "Jumbo
              Payload  Length"  field is set according to the real size of the jumbo payload (see
              the "-p" option).

       --payload-size, -P

              This options specifies the size of the jumbo payload.   If  left  unspecified,  the
              payload size is set to 0.

       --loop, -l

              This  option  instructs  the  jumbo6  tool  to send periodic IPv6 jumbograms to the
              victim node. The amount of time to pause between sending  IPv6  jumbograms  can  be
              specified by means of the "-z" option, and defaults to 1 second.

       --sleep, -z

              This  option  specifies the amount of time to pause between sending IPv6 jumbograms
              (when the "--loop" option is set). If left unspecified, it defaults to 1 second.

       --verbose, -v

              This option instructs the jumbo6 tool to be verbose.  When the option is set twice,
              the  tool  is  "very  verbose",  and  the tool also informs which packets have been
              accepted or discarded as a result of applying the specified filters.

       --help, -h

              Print help information for the jumbo6 tool.

EXAMPLES

       The following sections illustrate typical use cases of the jumbo6 tool.

       Example #1

       # jumbo6 -s fc00:1::/64 -d fc00:1::1 -P 100

       Send an IPv6 jumbogram to the host fc00:1::1. The IPv6 Source  Address  will  be  randomly
       selected  from  the  prefix fc00:1::/64, and a the payload of 100 bytes is included in the
       packet.
