tshark -h
TShark (Wireshark) 2.4. (v2.4.1--gf42a0d2b6c)
Dump and analyze network traffic.
See https://www.wireshark.org for more information. Usage: tshark [options] ... Capture interface:
-i <interface> name or idx of interface (def: first non-loopback)
-f <capture filter> packet filter in libpcap filter syntax -s <snaplen> packet snapshot length (def: appropriate maximum)
-p don't capture in promiscuous mode
-I capture in monitor mode, if available
-B <buffer size> size of kernel buffer (def: 2MB)
-y <link type> link layer type (def: first appropriate)
-D print list of interfaces and exit
-L print list of link-layer types of iface and exit Capture stop conditions:
-c <packet count> stop after n packets (def: infinite)
-a <autostop cond.> ... duration:NUM - stop after NUM seconds
filesize:NUM - stop this file after NUM KB
files:NUM - stop after NUM files
Capture output:
-b <ringbuffer opt.> ... duration:NUM - switch to next file after NUM secs
filesize:NUM - switch to next file after NUM KB
files:NUM - ringbuffer: replace after NUM files
RPCAP options:
-A <user>:<password> use RPCAP password authentication Input file:
-r <infile> set the filename to read from (- to read from stdin) Processing:
- perform a two-pass analysis
-M <packet count> perform session auto reset
-R <read filter> packet Read filter in Wireshark display filter syntax (requires -)
-Y <display filter> packet displaY filter in Wireshark display filter
syntax
-n disable all name resolutions (def: all enabled)
-N <name resolve flags> enable specific name resolution(s): "mnNtCd"
-d <layer_type>==<selector>,<decode_as_protocol> ...
"Decode As", see the man page for details
Example: tcp.port==,http
-H <hosts file> read a list of entries from a hosts file, which will
then be written to a capture file. (Implies -W n)
--enable-protocol <proto_name>
enable dissection of proto_name
--disable-protocol <proto_name>
disable dissection of proto_name
--enable-heuristic <short_name>
enable dissection of heuristic protocol
--disable-heuristic <short_name>
disable dissection of heuristic protocol
Output:
-w <outfile|-> write packets to a pcap-format file named "outfile"
(or to the standard output for "-")
-C <config profile> start with specified configuration profile
-F <output file type> set the output file type, default is pcapng
an empty "-F" option will list the file types
-V add output of packet tree (Packet Details)
-O <protocols> Only show packet details of these protocols, comma
separated
-P print packet summary even when writing to a file
-S <separator> the line separator to print between packets
-x add output of hex and ASCII dump (Packet Bytes)
-T pdml|ps|psml|json|jsonraw|ek|tabs|text|fields|?
format of text output (def: text)
-j <protocolfilter> protocols layers filter if -T ek|pdml|json selected
(e.g. "ip ip.flags text", filter does not expand chil
d
nodes, unless child is specified also in the filter)
-J <protocolfilter> top level protocol filter if -T ek|pdml|json selected (e.g. "http tcp", filter which expands all child node
s)
-e <field> field to print if -Tfields selected (e.g. tcp.port,
_ws.col.Info)
this option can be repeated to print multiple fields
-E<fieldsoption>=<value> set options for output when -Tfields selected:
bom=y|n print a UTF- BOM
header=y|n switch headers on and off
separator=/t|/s|<char> select tab, space, printable character as separator
occurrence=f|l|a print first, last or all occurrences of each field
aggregator=,|/s|<char> select comma, space, printable character as
aggregator
quote=d|s|n select double, single, no quotes for values
-t a|ad|d|dd|e|r|u|ud|? output format of time stamps (def: r: rel. to first)
-u s|hms output format of seconds (def: s: seconds)
-l flush standard output after each packet
-q be more quiet on stdout (e.g. when using statistics)
-Q only log true errors to stderr (quieter than -q)
-g enable group read access on the output file(s)
-W n Save extra information in the file, if supported.
n = write network address resolution information
-X <key>:<value> eXtension options, see the man page for details
-U tap_name PDUs export mode, see the man page for details
-z <statistics> various statistics, see the man page for details
--capture-comment <comment>
add a capture comment to the newly created
output file (only for pcapng)
--export-objects <protocol>,<destdir> save exported objects for a protocol to
a directory named "destdir" Miscellaneous:
-h display this help and exit
-v display version info and exit
-o <name>:<value> ... override preference setting
-K <keytab> keytab file to use for kerberos decryption
-G [report] dump one of several available reports and exit
default report="fields"
use "-G ?" for more help
