Wireshark 4.2.1 (v4.2.1rc0-11-gae025b2614ce)
Interactively dump and analyze network traffic.
See https://www.wireshark.org for more information.
Usage: wireshark [options] ... [ <infile> ]
Capture interface:
-i <interface>, --interface <interface>
name or idx of interface (def: first non-loopback)
-f <capture filter> packet filter in libpcap filter syntax
-s <snaplen>, --snapshot-length <snaplen>
packet snapshot length (def: appropriate maximum)
-p, --no-promiscuous-mode
don't capture in promiscuous mode
-I, --monitor-mode capture in monitor mode, if available
-B <buffer size>, --buffer-size <buffer size>
size of kernel buffer (def: 2MB)
-y <link type>, --linktype <link type>
link layer type (def: first appropriate)
--time-stamp-type <type> timestamp method for interface
-D, --list-interfaces print list of interfaces and exit
-L, --list-data-link-types
print list of link-layer types of iface and exit
--list-time-stamp-types print list of timestamp types for iface and exit
Capture display:
-k start capturing immediately (def: do nothing)
-S update packet display when new packets are captured
--update-interval interval between updates with new packets (def: 100ms)
-l turn on automatic scrolling while -S is in use
Capture stop conditions:
-c <packet count> stop after n packets (def: infinite)
-a <autostop cond.> ..., --autostop <autostop cond.> ...
duration:NUM - stop after NUM seconds
filesize:NUM - stop this file after NUM KB
files:NUM - stop after NUM files
packets:NUM - stop after NUM packets
Capture output:
-b <ringbuffer opt.> ..., --ring-buffer <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
packets:NUM - switch to next file after NUM packets
interval:NUM - switch to next file when the time is
an exact multiple of NUM secs
Input file:
-r <infile>, --read-file <infile>
set the filename to read from (no pipes or stdin!)
Processing:
-R <read filter>, --read-filter <read filter>
packet filter in Wireshark display filter syntax
-n disable all name resolutions (def: all enabled)
-N <name resolve flags> enable specific name resolution(s): "mnNtdv"
-d <layer_type>==<selector>,<decode_as_protocol> ...
"Decode As", see the man page for details
Example: tcp.port==8888,http
--enable-protocol <proto_name>
enable dissection of proto_name
--disable-protocol <proto_name>
disable dissection of proto_name
--only-protocols <proto_name>
Only enable dissection of these protocols, comma
separated. Disable everything else
--disable-all-protocols
Disable dissection of all protocols
--enable-heuristic <short_name>
enable dissection of heuristic protocol
--disable-heuristic <short_name>
disable dissection of heuristic protocol
User interface:
-C <config profile> start with specified configuration profile
-H hide the capture info dialog during packet capture
-Y <display filter>, --display-filter <display filter>
start with the given display filter
-g <packet number> go to specified packet number after "-r"
-J <jump filter> jump to the first packet matching the (display)
filter
-j search backwards for a matching packet after "-J"
-t (a|ad|adoy|d|dd|e|r|u|ud|udoy)[.[N]]|.[N]
format of time stamps (def: r: rel. to first)
-u s|hms output format of seconds (def: s: seconds)
-X <key>:<value> eXtension options, see man page for details
-z <statistics> show various statistics, see man page for details
Output:
-w <outfile|-> set the output filename (or '-' for stdout)
--capture-comment <comment>
add a capture file comment, if supported
--temp-dir <directory> write temporary files to this directory
(default: /tmp)
Diagnostic output:
--log-level <level> sets the active log level ("critical", "warning", etc.)
--log-fatal <level> sets level to abort the program ("critical" or "warning")
--log-domains <[!]list> comma-separated list of the active log domains
--log-fatal-domains <list>
list of domains that cause the program to abort
--log-debug <[!]list> list of domains with "debug" level
--log-noisy <[!]list> list of domains with "noisy" level
--log-file <path> file to output messages to (in addition to stderr)
Miscellaneous:
-h, --help display this help and exit
-v, --version display version info and exit
-P <key>:<path> persconf:path - personal configuration files
persdata:path - personal data files
-o <name>:<value> ... override preference or recent setting
-K <keytab> keytab file to use for kerberos decryption
--display <X display> X display to use
--fullscreen start Wireshark in full screen
