Text2pcap (Wireshark) 2.9.0 (v2.9.0rc0-1249-ga108e49d)
Generate a capture file from an ASCII hexdump of packets.
See https://www.wireshark.org for more information.
Usage: text2pcap [options] <infile> <outfile>
where <infile> specifies input filename (use - for standard input)
<outfile> specifies output filename (use - for standard output)
Input:
-o hex|oct|dec parse offsets as (h)ex, (o)ctal or (d)ecimal;
default is hex.
-t <timefmt> treat the text before the packet as a date/time code;
the specified argument is a format string of the sort
supported by strptime.
Example: The time "10:15:14.5476" has the format code
"%H:%M:%S."
NOTE: The subsecond component delimiter, '.', must be
given, but no pattern is required; the remaining
number is assumed to be fractions of a second.
NOTE: Date/time fields from the current date/time are
used as the default for unspecified fields.
-D the text before the packet starts with an I or an O,
indicating that the packet is inbound or outbound.
This is only stored if the output format is pcapng.
-a enable ASCII text dump identification.
The start of the ASCII text dump can be identified
and excluded from the packet data, even if it looks
like a HEX dump.
NOTE: Do not enable it if the input file does not
contain the ASCII text dump.
Output:
-l <typenum> link-layer type number; default is 1 (Ethernet). See
http://www.tcpdump.org/linktypes.html for a list of
numbers. Use this option if your dump is a complete
hex dump of an encapsulated packet and you wish to
specify the exact type of encapsulation.
Example: -l 7 for ARCNet packets.
-m <max-packet> max packet length in output; default is 262144
Prepend dummy header:
-e <l3pid> prepend dummy Ethernet II header with specified L3PID
(in HEX).
Example: -e 0x806 to specify an ARP packet.
-i <proto> prepend dummy IP header with specified IP protocol
(in DECIMAL).
Automatically prepends Ethernet header as well.
Example: -i 46
-4 <srcip>,<destip> prepend dummy IPv4 header with specified
dest and source address.
Example: -4 10.0.0.1,10.0.0.2
-6 <srcip>,<destip> replace IPv6 header with specified
dest and source address.
Example: -6 fe80:0:0:0:202:b3ff:fe1e:8329,2001:0db8:85a3:0000:0000:8a2e:0370:7334
-u <srcp>,<destp> prepend dummy UDP header with specified
source and destination ports (in DECIMAL).
Automatically prepends Ethernet & IP headers as well.
Example: -u 1000,69 to make the packets look like
TFTP/UDP packets.
-T <srcp>,<destp> prepend dummy TCP header with specified
source and destination ports (in DECIMAL).
Automatically prepends Ethernet & IP headers as well.
Example: -T 50,60
-s <srcp>,<dstp>,<tag> prepend dummy SCTP header with specified
source/dest ports and verification tag (in DECIMAL).
Automatically prepends Ethernet & IP headers as well.
Example: -s 30,40,34
-S <srcp>,<dstp>,<ppi> prepend dummy SCTP header with specified
source/dest ports and verification tag 0.
Automatically prepends a dummy SCTP DATA
chunk header with payload protocol identifier ppi.
Example: -S 30,40,34
Miscellaneous:
-h display this help and exit.
-d show detailed debug of parser states.
-q generate no output at all (automatically disables -d).
-n use pcapng instead of pcap as output format.
