In these cases, if you forgot to unroll your set of packets, only the first element of the list you forgot to generate will be used to assemble the packet.ĭisplays a list of summaries of each packetĭisplays the preferred representation (usually nsummary()) Some operations (like building the string from a packet) can’t work on a set of packets. > a = IP ( dst = ") > a > b = IP ( ttl = ) > b > c = TCP ( dport = ) > This implicitly defines a set of packets, generated using a kind of cartesian product between all the fields.
Each field of the whole packet (ever layers) can be a set.

Let see how to specify sets of packets as easily. Return a Scapy command that can generate the packetįor the moment, we have only generated one packet. Same as show but on the assembled packet (checksum is calculated, for instance)įills a format string with fields values of the packetĭraws a PostScript diagram with explained dissection psdump ( "/tmp/isakmp_pkt.eps", layer_shift = 1 ) If this is too verbose, the method hide_defaults() will delete every field that has the same value as the default: That’s because I consider that each field has its value imposed by the original string. We see that a dissected packet has all its fields filled.
