pcap provides a pcap_set_tstamp_type function, which can be used to request hardware timestamps from a supporting kernel. This patch adds support for aforementioned function as well as two new command line options to dumpcap, wireshark and tshark: --list-time-stamp-types List time stamp types supported for the interface --time-stamp-type <type> Change the interface's timestamp method Name choice mimics those used by tcpdump(1), which already supports this feature. However, unlike tcpdump, we provide both options unconditionally. If Wireshark was configured without pcap_set_tstamp_type being available, --list-time-stamp-types reports an empty list.

=head1 DESCRIPTION
|
|
|
|
B<Wireshark> is a GUI network protocol analyzer. It lets you
|
|
interactively browse packet data from a live network or from a
|
|
previously saved capture file. B<Wireshark>'s native capture file format
|
|
is B<pcap> format, which is also the format used by B<tcpdump> and
|
|
various other tools.
|
|
|
|
B<Wireshark> can read / import the following file formats:

|
|
There is no need to tell B<Wireshark> what type of
|
|
file you are reading; it will determine the file type by itself.
|
|
B<Wireshark> is also capable of reading any of these file formats if they
|
|
are compressed using gzip. B<Wireshark> recognizes this directly from
|
|
the file; the '.gz' extension is not required for this purpose.
|
|
|
|
Like other protocol analyzers, B<Wireshark>'s main window shows 3 views
|
|
of a packet. It shows a summary line, briefly describing what the
|
|
packet is. A packet details display is shown, allowing you to drill
|
|
down to exact protocol or field that you interested in. Finally, a hex
|
|
dump shows you exactly what the packet looks like when it goes over the
|
|
wire.
|
|
|
|
In addition, B<Wireshark> has some features that make it unique. It can
|
|
assemble all the packets in a TCP conversation and show you the ASCII
|
|
(or EBCDIC, or hex) data in that conversation. Display filters in
|
|
B<Wireshark> are very powerful; more fields are filterable in B<Wireshark>
|
|
than in other protocol analyzers, and the syntax you can use to create
|
|
your filters is richer. As B<Wireshark> progresses, expect more and more
|
|
protocol fields to be allowed in display filters.
|
|
|
|
Packet capturing is performed with the pcap library. The capture filter
|
|
syntax follows the rules of the pcap library. This syntax is different
|
|
from the display filter syntax.
|
|
|
|
Compressed file support uses (and therefore requires) the zlib library.
|
|
If the zlib library is not present, B<Wireshark> will compile, but will
|
|
be unable to read compressed files.
|
|
|
|
The pathname of a capture file to be read can be specified with the
|
|
B<-r> option or can be specified as a command-line argument.
|
|
|
|
=head1 OPTIONS
|
|
|
|
Most users will want to start B<Wireshark> without options and configure
|
|
it from the menus instead. Those users may just skip this section.
|
|
|
|
=over 4
|
|
|
|
=item -a E<lt>capture autostop conditionE<gt>
|
|
|
|
Specify a criterion that specifies when B<Wireshark> is to stop writing
|
|
to a capture file. The criterion is of the form I<test>B<:>I<value>,
|
|
where I<test> is one of:
|
|
|
|
B<duration>:I<value> Stop writing to a capture file after I<value> seconds have
|
|
elapsed.
|
|
|
|
B<filesize>:I<value> Stop writing to a capture file after it reaches a size of
|
|
I<value> kB. If this option is used together with the -b option, Wireshark
|
|
will stop writing to the current capture file and switch to the next one if
|
|
filesize is reached. Note that the filesize is limited to a maximum value of
|
|
2 GiB.
|
|
|
|
B<files>:I<value> Stop writing to capture files after I<value> number of files
|
|
were written.
|
|
|
|
=item -b E<lt>capture ring buffer optionE<gt>
|
|
|
|
Cause B<Wireshark> to run in "multiple files" mode. In "multiple files" mode,
|
|
B<Wireshark> will write to several capture files. When the first capture file
|
|
fills up, B<Wireshark> will switch writing to the next file and so on.
|
|
|
|
The created filenames are based on the filename given with the B<-w> flag,
|
|
the number of the file and on the creation date and time,
|
|
e.g. outfile_00001_20050604120117.pcap, outfile_00002_20050604120523.pcap, ...
|
|
|
|
With the I<files> option it's also possible to form a "ring buffer".
|
|
This will fill up new files until the number of files specified,
|
|
at which point B<Wireshark> will discard the data in the first file and start
|
|
writing to that file and so on. If the I<files> option is not set,
|
|
new files filled up until one of the capture stop conditions match (or
|
|
until the disk is full).
|
|
|
|
The criterion is of the form I<key>B<:>I<value>,
|
|
where I<key> is one of:
|
|
|
|
B<duration>:I<value> switch to the next file after I<value> seconds have
|
|
elapsed, even if the current file is not completely filled up.
|
|
|
|
B<interval>:I<value> switch to the next file when the time is an exact
|
|
multiple of I<value> seconds
|
|
|
|
B<filesize>:I<value> switch to the next file after it reaches a size of
|
|
I<value> kB. Note that the filesize is limited to a maximum value of 2 GiB.
|
|
|
|
B<files>:I<value> begin again with the first file after I<value> number of
|
|
files were written (form a ring buffer). This value must be less than 100000.
|
|
Caution should be used when using large numbers of files: some filesystems do
|
|
not handle many files in a single directory well. The B<files> criterion
|
|
requires either B<duration>, B<interval> or B<filesize> to be specified to
|
|
control when to go to the next file. It should be noted that each B<-b>
|
|
parameter takes exactly one criterion; to specify two criterion, each must be
|
|
preceded by the B<-b> option.
|
|
|
|
Example: B<-b filesize:1000 -b files:5> results in a ring buffer of five files
|
|
of size one megabyte each.
|
|
|
|
=item -B E<lt>capture buffer sizeE<gt>
|
|
|
|
Set capture buffer size (in MiB, default is 2 MiB). This is used by
|
|
the capture driver to buffer packet data until that data can be written
|
|
to disk. If you encounter packet drops while capturing, try to increase
|
|
this size. Note that, while B<Wireshark> attempts to set the buffer size
|
|
to 2 MiB by default, and can be told to set it to a larger value, the
|
|
system or interface on which you're capturing might silently limit the
|
|
capture buffer size to a lower value or raise it to a higher value.
|
|
|
|
This is available on UNIX systems with libpcap 1.0.0 or later and on
|
|
Windows. It is not available on UNIX systems with earlier versions of
|
|
libpcap.
|
|
|
|
This option can occur multiple times. If used before the first
|
|
occurrence of the B<-i> option, it sets the default capture buffer size.
|
|
If used after an B<-i> option, it sets the capture buffer size for
|
|
the interface specified by the last B<-i> option occurring before
|
|
this option. If the capture buffer size is not set specifically,
|
|
the default capture buffer size is used instead.
|
|
|
|
=item -c E<lt>capture packet countE<gt>
|
|
|
|
Set the maximum number of packets to read when capturing live
|
|
data.
|
|
|
|
=item -C E<lt>configuration profileE<gt>
|
|
|
|
Start with the given configuration profile.
|
|
|
|
=item -d E<lt>layer typeE<gt>==E<lt>selectorE<gt>,E<lt>decode-as protocolE<gt>
|
|
|
|
Like Wireshark's B<Decode As...> feature, this lets you specify how a
|
|
layer type should be dissected. If the layer type in question (for example,
|
|
B<tcp.port> or B<udp.port> for a TCP or UDP port number) has the specified
|
|
selector value, packets should be dissected as the specified protocol.
|
|
|
|
Example: B<-d tcp.port==8888,http> will decode any traffic running over
|
|
TCP port 8888 as HTTP.
|
|
|
|
See the tshark(1) manual page for more examples.
|
|
|
|
=item -D
|
|
|
|
Print a list of the interfaces on which B<Wireshark> can capture, and
|
|
exit. For each network interface, a number and an
|
|
interface name, possibly followed by a text description of the
|
|
interface, is printed. The interface name or the number can be supplied
|
|
to the B<-i> flag to specify an interface on which to capture.
|
|
|
|
This can be useful on systems that don't have a command to list them
|
|
(UNIX systems lacking B<ifconfig -a> or Linux systems lacking
|
|
B<ip link show>). The number can be useful on Windows systems, where
|
|
the interface name might be a long name or a GUID.
|
|
|
|
Note that "can capture" means that B<Wireshark> was able to open
|
|
that device to do a live capture; if, on your system, a program doing a
|
|
network capture must be run from an account with special privileges (for
|
|
example, as root), then, if B<Wireshark> is run with the B<-D> flag and
|
|
is not run from such an account, it will not list any interfaces.
|
|
|
|
=item --display=E<lt>X display to useE<gt>
|
|
|
|
Specifies the X display to use. A hostname and screen (otherhost:0.0)
|
|
or just a screen (:0.0) can be specified. This option is not available
|
|
under Windows.
|
|
|
|
=item -f E<lt>capture filterE<gt>
|
|
|
|
Set the capture filter expression.
|
|
|
|
This option can occur multiple times. If used before the first
|
|
occurrence of the B<-i> option, it sets the default capture filter expression.
|
|
If used after an B<-i> option, it sets the capture filter expression for
|
|
the interface specified by the last B<-i> option occurring before
|
|
this option. If the capture filter expression is not set specifically,
|
|
the default capture filter expression is used if provided.
|
|
|
|
Pre-defined capture filter names, as shown in the GUI menu item Capture->Capture Filters,
|
|
can be used by prefixing the argument with "predef:".
|
|
Example: B<-f "predef:MyPredefinedHostOnlyFilter">
|
|
|
|
=item --fullscreen
|
|
|
|
Start Wireshark in full screen mode (kiosk mode). To exit from fullscreen mode,
|
|
open the View menu and select the Full Screen option. Alternatively, press the
|
|
F11 key (or Ctrl + Cmd + F for macOS).
|
|
|
|
=item -g E<lt>packet numberE<gt>
|
|
|
|
After reading in a capture file using the B<-r> flag, go to the given I<packet number>.
|
|
|
|
=item -h
|
|
|
|
Print the version and options and exit.
|
|
|
|
=item -H
|
|
|
|
Hide the capture info dialog during live packet capture.
|
|
|
|
=item -i E<lt>capture interfaceE<gt>|-
|
|
|
|
Set the name of the network interface or pipe to use for live packet
|
|
capture.
|
|
|
|
Network interface names should match one of the names listed in
|
|
"B<wireshark -D>" (described above); a number, as reported by
|
|
"B<wireshark -D>", can also be used. If you're using UNIX, "B<netstat
|
|
-i>" or "B<ifconfig -a>" might also work to list interface names,
|
|
although not all versions of UNIX support the B<-a> flag to B<ifconfig>.
|
|
|
|
If no interface is specified, B<Wireshark> searches the list of
|
|
interfaces, choosing the first non-loopback interface if there are any
|
|
non-loopback interfaces, and choosing the first loopback interface if
|
|
there are no non-loopback interfaces. If there are no interfaces at all,
|
|
B<Wireshark> reports an error and doesn't start the capture.
|
|
|
|
Pipe names should be either the name of a FIFO (named pipe) or ``-'' to
|
|
read data from the standard input. On Windows systems, pipe names must be
|
|
of the form ``\\pipe\.\B<pipename>''. Data read from pipes must be in
|
|
standard pcap format.
|
|
|
|
This option can occur multiple times. When capturing from multiple
|
|
interfaces, the capture file will be saved in pcap-ng format.
|
|
|
|
=item -I
|
|
|
|
Put the interface in "monitor mode"; this is supported only on IEEE
|
|
802.11 Wi-Fi interfaces, and supported only on some operating systems.
|
|
|
|
Note that in monitor mode the adapter might disassociate from the
|
|
network with which it's associated, so that you will not be able to use
|
|
any wireless networks with that adapter. This could prevent accessing
|
|
files on a network server, or resolving host names or network addresses,
|
|
if you are capturing in monitor mode and are not connected to another
|
|
network with another adapter.
|
|
|
|
This option can occur multiple times. If used before the first
|
|
occurrence of the B<-i> option, it enables the monitor mode for all interfaces.
|
|
If used after an B<-i> option, it enables the monitor mode for
|
|
the interface specified by the last B<-i> option occurring before
|
|
this option.
|
|
|
|
=item -j
|
|
|
|
Use after B<-J> to change the behavior when no exact match is found for
|
|
the filter. With this option select the first packet before.
|
|
|
|
=item -J E<lt>jump filterE<gt>
|
|
|
|
After reading in a capture file using the B<-r> flag, jump to the packet
|
|
matching the filter (display filter syntax). If no exact match is found
|
|
the first packet after that is selected.
|
|
|
|
=item -k
|
|
|
|
Start the capture session immediately. If the B<-i> flag was
|
|
specified, the capture uses the specified interface. Otherwise,
|
|
B<Wireshark> searches the list of interfaces, choosing the first
|
|
non-loopback interface if there are any non-loopback interfaces, and
|
|
choosing the first loopback interface if there are no non-loopback
|
|
interfaces; if there are no interfaces, B<Wireshark> reports an error and
|
|
doesn't start the capture.
|
|
|
|
=item -K E<lt>keytabE<gt>
|
|
|
|
Load kerberos crypto keys from the specified keytab file.
|
|
This option can be used multiple times to load keys from several files.
|
|
|
|
Example: B<-K krb5.keytab>
|
|
|
|
=item -l
|
|
|
|
Turn on automatic scrolling if the packet display is being updated
|
|
automatically as packets arrive during a capture (as specified by the
|
|
B<-S> flag).
|
|
|
|
=item -L
|
|
|
|
List the data link types supported by the interface and exit.
|
|
|
|
=item -n
|
|
|
|
Disable network object name resolution (such as hostname, TCP and UDP port
|
|
names), the B<-N> flag might override this one.
|
|
|
|
=item -N E<lt>name resolving flagsE<gt>
|
|
|
|
Turn on name resolving only for particular types of addresses and port
|
|
numbers, with name resolving for other types of addresses and port
|
|
numbers turned off. This flag overrides B<-n> if both B<-N> and B<-n> are
|
|
present. If both B<-N> and B<-n> flags are not present, all name resolutions
|
|
are turned on.
|
|
|
|
The argument is a string that may contain the letters:
|
|
|
|
B<m> to enable MAC address resolution
|
|
|
|
B<n> to enable network address resolution
|
|
|
|
B<N> to enable using external resolvers (e.g., DNS) for network address
|
|
resolution
|
|
|
|
B<t> to enable transport-layer port number resolution
|
|
|
|
B<d> to enable resolution from captured DNS packets
|
|
|
|
=item -o E<lt>preference/recent settingE<gt>
|
|
|
|
Set a preference or recent value, overriding the default value and any value
|
|
read from a preference/recent file. The argument to the flag is a string of
|
|
the form I<prefname>B<:>I<value>, where I<prefname> is the name of the
|
|
preference/recent value (which is the same name that would appear in the
|
|
preference/recent file), and I<value> is the value to which it should be set.
|
|
Since B<Ethereal> 0.10.12, the recent settings replaces the formerly used
|
|
-B, -P and -T flags to manipulate the GUI dimensions.
|
|
|
|
If I<prefname> is "uat", you can override settings in various user access
|
|
tables using the form uatB<:>I<uat filename>:I<uat record>. I<uat filename>
|
|
must be the name of a UAT file, e.g. I<user_dlts>. I<uat_record> must be in
|
|
the form of a valid record for that file, including quotes. For instance, to
|
|
specify a user DLT from the command line, you would use
|
|
|
|
-o "uat:user_dlts:\"User 0 (DLT=147)\",\"cops\",\"0\",\"\",\"0\",\"\""
|
|
|
|
=item -p
|
|
|
|
I<Don't> put the interface into promiscuous mode. Note that the
|
|
interface might be in promiscuous mode for some other reason; hence,
|
|
B<-p> cannot be used to ensure that the only traffic that is captured is
|
|
traffic sent to or from the machine on which B<Wireshark> is running,
|
|
broadcast traffic, and multicast traffic to addresses received by that
|
|
machine.
|
|
|
|
This option can occur multiple times. If used before the first
|
|
occurrence of the B<-i> option, no interface will be put into the
|
|
promiscuous mode.
|
|
If used after an B<-i> option, the interface specified by the last B<-i>
|
|
option occurring before this option will not be put into the
|
|
promiscuous mode.
|
|
|
|
=item -P E<lt>path settingE<gt>
|
|
|
|
Special path settings usually detected automatically. This is used for
|
|
special cases, e.g. starting Wireshark from a known location on an USB stick.
|
|
|
|
The criterion is of the form I<key>B<:>I<path>, where I<key> is one of:
|
|
|
|
B<persconf>:I<path> path of personal configuration files, like the
|
|
preferences files.
|
|
|
|
B<persdata>:I<path> path of personal data files, it's the folder initially
|
|
opened. After the very first initialization, the recent file will keep the
|
|
folder last used.
|
|
|
|
=item -r E<lt>infileE<gt>
|
|
|
|
Read packet data from I<infile>, can be any supported capture file format
|
|
(including gzipped files). It's not possible to use named pipes or stdin
|
|
here! To capture from a pipe or from stdin use B<-i ->
|
|
|
|
=item -R E<lt>read (display) filterE<gt>
|
|
|
|
When reading a capture file specified with the B<-r> flag, causes the
|
|
specified filter (which uses the syntax of display filters, rather than
|
|
that of capture filters) to be applied to all packets read from the
|
|
capture file; packets not matching the filter are discarded.
|
|
|
|
=item -s E<lt>capture snaplenE<gt>
|
|
|
|
Set the default snapshot length to use when capturing live data.
|
|
No more than I<snaplen> bytes of each network packet will be read into
|
|
memory, or saved to disk. A value of 0 specifies a snapshot length of
|
|
262144, so that the full packet is captured; this is the default.
|
|
|
|
This option can occur multiple times. If used before the first
|
|
occurrence of the B<-i> option, it sets the default snapshot length.
|
|
If used after an B<-i> option, it sets the snapshot length for
|
|
the interface specified by the last B<-i> option occurring before
|
|
this option. If the snapshot length is not set specifically,
|
|
the default snapshot length is used if provided.
|
|
|
|
=item -S

|
|
window. The format can be one of:
|
|
|
|
B<a> absolute: The absolute time, as local time in your time zone,
|
|
is the actual time the packet was captured, with no date displayed
|
|
|
|
B<ad> absolute with date: The absolute date, displayed as YYYY-MM-DD,
|
|
and time, as local time in your time zone, is the actual time and date
|
|
the packet was captured
|
|
|
|
B<adoy> absolute with date using day of year: The absolute date,
|
|
displayed as YYYY/DOY, and time, as local time in your time zone,
|
|
is the actual time and date the packet was captured
|
|
|
|
B<d> delta: The delta time is the time since the previous packet was
|
|
captured
|
|
|
|
B<dd> delta_displayed: The delta_displayed time is the time since the
|
|
previous displayed packet was captured
|
|
|
|
B<e> epoch: The time in seconds since epoch (Jan 1, 1970 00:00:00)
|
|
|
|
B<r> relative: The relative time is the time elapsed between the first packet
|
|
and the current packet
|
|
|
|
B<u> UTC: The absolute time, as UTC, is the actual time the packet was
|
|
captured, with no date displayed
|
|
|
|
B<ud> UTC with date: The absolute date, displayed as YYYY-MM-DD,
|
|
and time, as UTC, is the actual time and date the packet was captured

B<udoy> UTC with date using day of year: The absolute date, displayed
|
|
as YYYY/DOY, and time, as UTC, is the actual time and date the packet
|
|
was captured
|
|
|
|
The default format is relative.

|
|
B<lua_script>:I<lua_script_filename> tells B<Wireshark> to load the given script in addition to the
|
|
default Lua scripts.
|
|
|
|
B<lua_script>I<num>:I<argument> tells B<Wireshark> to pass the given argument
|
|
to the lua script identified by 'num', which is the number indexed order of the 'lua_script' command.
|
|
For example, if only one script was loaded with '-X lua_script:my.lua', then '-X lua_script1:foo'
|
|
will pass the string 'foo' to the 'my.lua' script. If two scripts were loaded, such as '-X lua_script:my.lua'
|
|
and '-X lua_script:other.lua' in that order, then a '-X lua_script2:bar' would pass the string 'bar' to the second lua
|
|
script, namely 'other.lua'.
|
|
|
|
B<read_format>:I<file_format> tells B<Wireshark> to use the given file format to read in the
|
|
file (the file given in the B<-r> command option).
|
|
|
|
B<stdin_descr>:I<description> tells B<Wireshark> to use the given description when

|
|
This option can occur multiple times. If used before the first
|
|
occurrence of the B<-i> option, it sets the default capture link type.
|
|
If used after an B<-i> option, it sets the capture link type for
|
|
the interface specified by the last B<-i> option occurring before
|
|
this option. If the capture link type is not set specifically,
|
|
the default capture link type is used if provided.

This is a flaw that might be fixed in the future.
|

|
|
This option can be used multiple times on the command line.
|

|
|
If the optional I<filter> is provided, the stats will only be calculated
|
|
on those calls that match that filter.
|
|
|
|
Example: B<-z "smb,srt,ip.addr==1.2.3.4"> will collect stats only for
|
|
SMB packets exchanged by the host at IP address 1.2.3.4 .
|
|
|
|
=item B<-z> voip,calls
|
|
|
|
This option will show a window that shows VoIP calls found in the capture file.
|
|
This is the same window shown as when you go to the Statistics Menu and choose
|
|
VoIP Calls.
|
|
|
|
Example: B<-z voip,calls>
|
|
|
|
=item B<-z> wlan,stat[,<filter>]
|
|
|
|
Show IEEE 802.11 network and station statistics.
|

|
|
=item B<-z> wsp,stat[,<filter>]
|
|
|
|
Show WSP packet counters.

|
|
relative to the already loaded one.
|
|
|

=item File:Close
|
|
|
|
Open or close a capture file. The I<File:Open> dialog box
|
|
allows a filter to be specified; when the capture file is read, the
|
|
filter is applied to all packets read from the file, and packets not
|

Save the current capture, or the packets currently displayed from that
|
|
capture, to a file. Check boxes let you select whether to save all
|
|
packets, or just those that have passed the current display filter and/or
|
|
those that are currently marked, and an option menu lets you select (from
|

=item File:File Set:List Files
|
|
|
|
Show a dialog box that lists all files of the file set matching the currently
|
|
loaded file. A file set is a compound of files resulting from a capture using
|
|
the "multiple files" / "ringbuffer" mode, recognizable by the filename pattern,
|
|
e.g.: Filename_00001_20050604101530.pcap.

=item File:Export
|
|
|
|
Export captured data into an external format. Note: the data cannot be

|
imported back into Wireshark, so be sure to keep the capture file.
|
|
|
|
=item File:Print
|
|
|
|
Print packet data from the current capture. You can select the range of
|
|
packets to be printed (which packets are printed), and the output format of
|
|
each packet (how each packet is printed). The output format will be similar
|
|
to the displayed values, so a summary line, the packet details view, and/or
|
|
the hex dump of the packet can be printed.
|
|
|
|
Printing options can be set with the I<Edit:Preferences> menu item, or in the
|
|
dialog box popped up by this menu item.

|
|
|
|
Copies the fieldname of the selected field in the protocol tree to

|
|
|
|
Copies the value of the selected field in the protocol tree to

=item Edit:Copy:As Filter
|
|
|
|
Create a display filter based on the data currently highlighted in the
|
|
packet details and copy that filter to the clipboard.
|
|
|
|
If that data is a field that can be tested in a display filter
|
|
expression, the display filter will test that field; otherwise, the
|
|
display filter will be based on the absolute offset within the packet.
|
|
Therefore it could be unreliable if the packet contains protocols with
|
|
variable-length headers, such as a source-routed token-ring packet.
|
|
|
|
=item Edit:Find Packet
|
|
|
|
Search forward or backward, starting with the currently selected packet
|
|
(or the most recently selected packet, if no packet is selected). Search
|
|
criteria can be a display filter expression, a string of hexadecimal
|
|
digits, or a text string.
|
|
|
|
When searching for a text string, you can search the packet data, or you
|
|
can search the text in the Info column in the packet list pane or in the
|
|
packet details pane.
|
|
|
|
Hexadecimal digits can be separated by colons, periods, or dashes.
|
|
Text string searches can be ASCII or Unicode (or both), and may be
|
|
case insensitive.
|

|
=item Edit:Mark Packet (toggle)
|
|
|
|
Mark (or unmark if currently marked) the selected packet. The field
|
|
"frame.marked" is set for packets that are marked, so that, for example,
|
|
a display filters can be used to display only marked packets, and so that

the L</"Edit:Find Packet"> dialog can be used to find the next or previous
|
|
marked packet.
|

|
|
|
|
=item Edit:Time Reference:Set Time Reference (toggle)
|
|
|
|
Set (or unset if currently set) the selected packet as a Time Reference packet.
|
|
When a packet is set as a Time Reference packet, the timestamps in the packet
|
|
list pane will be replaced with the string "*REF*".
|
|
The relative time timestamp in later packets will then be calculated relative
|
|
to the timestamp of this Time Reference packet and not the first packet in
|
|
the capture.
|
|
|
|
Packets that have been selected as Time Reference packets will always be
|
|
displayed in the packet list pane. Display filters will not affect or
|
|
hide these packets.
|
|
|
|
If there is a column displayed for "Cumulative Bytes" this counter will
|

|
|
|
|
=item View:Coloring Rules
|
|
|
|
Change the foreground and background colors of the packet information in
|
|
the list of packets, based upon display filters. The list of display
|
|
filters is applied to each packet sequentially. After the first display
|
|
filter matches a packet, any additional display filters in the list are
|
|
ignored. Therefore, if you are filtering on the existence of protocols,
|
|
you should list the higher-level protocols first, and the lower-level
|
|
protocols last.
|
|
|
|
=over
|
|
|
|
=item How Colorization Works
|
|
|
|
Packets are colored according to a list of color filters. Each filter
|
|
consists of a name, a filter expression and a coloration. A packet is
|
|
colored according to the first filter that it matches. Color filter
|
|
expressions use exactly the same syntax as display filter expressions.
|
|
|
|
When Wireshark starts, the color filters are loaded from:
|
|
|
|
=over
|
|
|
|
=item 1.
|
|
|
|
The user's personal color filters file or, if that does not exist,
|
|
|
|
=item 2.
|
|
|
|
The global color filters file.
|
|
|
|
=back
|
|
|
|
If neither of these exist then the packets will not be colored.
|
|
|
|
=back
|
|
|
|
=item View:Show Packet In New Window
|
|
|
|
Create a new window containing a packet details view and a hex dump
|
|
window of the currently selected packet; this window will continue to
|
|
display that packet's details and data even if another packet is
|
|
selected.
|
|
|
|
=item View:Reload
|
|
|
|
Reload a capture file. Same as I<File:Close> and I<File:Open> the same
|
|
file again.
|
|
|
|
=item Go:Back
|
|
|
|
Go back in previously visited packets history.
|
|
|
|
=item Go:Forward
|
|
|
|
Go forward in previously visited packets history.
|
|
|
|
=item Go:Go To Packet
|
|
|
|
Go to a particular numbered packet.
|
|
|
|
=item Go:Go To Corresponding Packet
|
|
|
|
If a field in the packet details pane containing a packet number is
|
|
selected, go to the packet number specified by that field. (This works
|
|
only if the dissector that put that entry into the packet details put it
|
|
into the details as a filterable field rather than just as text.) This
|
|
can be used, for example, to go to the packet for the request
|
|
corresponding to a reply, or the reply corresponding to a request, if
|
|
that packet number has been put into the packet details.
|
|
|
|
=item Go:Previous Packet
|

|
|
=item Go:Previous Packet In Conversation
|
|
|
|
=item Go:Next Packet In Conversation
|

Go to the previous / next packet of the conversation (TCP, UDP or IP)
|
|
|
|
=item Capture:Interfaces
|
|
|
|
Shows a dialog box with all currently known interfaces and displaying the
|
|
current network traffic amount. Capture sessions can be started from here.
|
|
Beware: keeping this box open results in high system load!
|
|
|
|
=item Capture:Options
|
|
|
|
Initiate a live packet capture (see L</"Capture Options Dialog">
|
|
below). If no filename is specified, a temporary file will be created
|
|
to hold the capture. The location of the file can be chosen by setting your
|
|
TMPDIR environment variable before starting B<Wireshark>. Otherwise, the
|
|
default TMPDIR location is system-dependent, but is likely either F</var/tmp>
|
|
or F</tmp>.
|
|
|
|
=item Capture:Start
|
|
|
|
Start a live packet capture with the previously selected options. This won't
|
|
open the options dialog box, and can be convenient for repeatedly capturing
|
|
with the same options.
|
|
|
|
=item Capture:Stop
|
|
|
|
Stop a running live capture.
|
|
|
|
=item Capture:Restart
|
|
|
|
While a live capture is running, stop it and restart with the same options
|
|
again. This can be convenient to remove irrelevant packets, if no valuable
|
|
packets were captured so far.
|
|
|
|
=item Capture:Capture Filters
|
|
|
|
Edit the saved list of capture filters, allowing filters to be added,
|
|
changed, or deleted.
|
|
|
|
=item Analyze:Display Filters
|
|
|
|
Edit the saved list of display filters, allowing filters to be added,
|
|
changed, or deleted.
|
|
|
|
=item Analyze:Display Filter Macros
|
|
|
|
Create shortcuts for complex macros
|
|
|
|
=item Analyze:Apply as Filter
|
|
|
|
Create a display filter based on the data currently highlighted in the
|
|
packet details and apply the filter.
|
|
|
|
If that data is a field that can be tested in a display filter
|
|
expression, the display filter will test that field; otherwise, the
|
|
display filter will be based on the absolute offset within the packet.
|
|
Therefore it could be unreliable if the packet contains protocols with
|
|
variable-length headers, such as a source-routed token-ring packet.
|
|
|
|
The B<Selected> option creates a display filter that tests for a match
|
|
of the data; the B<Not Selected> option creates a display filter that
|
|
tests for a non-match of the data. The B<And Selected>, B<Or Selected>,
|
|
B<And Not Selected>, and B<Or Not Selected> options add to the end of
|
|
the display filter in the strip at the top (or bottom) an AND or OR
|
|
operator followed by the new display filter expression.
|
|
|
|
=item Analyze:Prepare a Filter
|
|
|
|
Create a display filter based on the data currently highlighted in the
|
|
packet details. The filter strip at the top (or bottom) is updated but
|
|
it is not yet applied.
|
|
|
|
=item Analyze:Enabled Protocols
|
|
|
|
Allow protocol dissection to be enabled or disabled for a specific
|
|
protocol. Individual protocols can be enabled or disabled by clicking
|
|
on them in the list or by highlighting them and pressing the space bar.
|
|
The entire list can be enabled, disabled, or inverted using the buttons
|
|
below the list.
|
|
|
|
When a protocol is disabled, dissection in a particular packet stops
|
|
when that protocol is reached, and Wireshark moves on to the next packet.
|
|
Any higher-layer protocols that would otherwise have been processed will
|
|
not be displayed. For example, disabling TCP will prevent the dissection
|
|
and display of TCP, HTTP, SMTP, Telnet, and any other protocol exclusively
|
|
dependent on TCP.
|
|
|
|
The list of protocols can be saved, so that Wireshark will start up with
|
|
the protocols in that list disabled.
|
|
|
|
=item Analyze:Decode As
|
|
|
|
If you have a packet selected, present a dialog allowing you to change
|
|
which dissectors are used to decode this packet. The dialog has one
|
|
panel each for the link layer, network layer and transport layer
|
|
protocol/port numbers, and will allow each of these to be changed
|
|
independently. For example, if the selected packet is a TCP packet to
|
|
port 12345, using this dialog you can instruct Wireshark to decode all
|
|
packets to or from that TCP port as HTTP packets.
|
|
|
|
=item Analyze:User Specified Decodes
|
|
|
|
Create a new window showing whether any protocol ID to dissector
|
|
mappings have been changed by the user. This window also allows the
|
|
user to reset all decodes to their default values.
|
|
|
|
=item Analyze:Follow TCP Stream
|
|
|
|
If you have a TCP packet selected, display the contents of the data
|
|
stream for the TCP connection to which that packet belongs, as text, in
|
|
a separate window, and leave the list of packets in a filtered state,
|
|
with only those packets that are part of that TCP connection being
|
|
displayed. You can revert to your old view by pressing ENTER in the
|
|
display filter text box, thereby invoking your old display filter (or
|
|
resetting it back to no display filter).
|
|
|
|
The window in which the data stream is displayed lets you select:
|
|
|
|
=over 8
|
|
|
|
=item *
|
|
|
|
whether to display the entire conversation, or one or the other side of
|
|
it;
|
|
|
|
=item *
|
|
|
|
whether the data being displayed is to be treated as ASCII or EBCDIC
|
|
text or as raw hex data;
|
|
|
|
=back
|
|
|
|
and lets you print what's currently being displayed, using the same
|
|
print options that are used for the I<File:Print Packet> menu item, or
|
|
save it as text to a file.
|
|
|
|
=item Analyze:Follow UDP Stream
|
|
|

|
=item Analyze:Expert Info
|
|
|
|
=item Analyze:Expert Info Composite
|
|
|
|
(Kind of) a log of anomalies found by Wireshark in a capture file.
|
|
|
|
=item Analyze:Conversation Filter
|
|
|
|
=item Statistics:Summary
|
|
|
|
Show summary information about the capture, including elapsed time,
|
|
packet counts, byte counts, and the like. If a display filter is in
|
|
effect, summary information will be shown about the capture and about
|
|
the packets currently being displayed.
|
|
|
|
=item Statistics:Protocol Hierarchy
|
|
|
|
Show the number of packets, and the number of bytes in those packets,
|
|
for each protocol in the trace. It organizes the protocols in the same
|
|
hierarchy in which they were found in the trace. Besides counting the
|
|
packets in which the protocol exists, a count is also made for packets
|
|
in which the protocol is the last protocol in the stack. These
|
|
last-protocol counts show you how many packets (and the byte count
|
|
associated with those packets) B<ended> in a particular protocol. In
|
|
the table, they are listed under "End Packets" and "End Bytes".
|
|
|
|
=item Statistics:Conversations
|
|
|
|
Lists of conversations; selectable by protocol. See Statistics:Conversation List below.
|
|
|
|
=item Statistics:End Points
|
|
|
|
List of End Point Addresses by protocol with packets/bytes/.... counts.
|
|
|
|
=item Statistics:Packet Lengths
|
|
|
|
Grouped counts of packet lengths (0-19 bytes, 20-39 bytes, ...)
|
|
|
|
=item Statistics:IO Graphs
|
|
|
|
Open a window where up to 5 graphs in different colors can be displayed
|
|
to indicate number of packets or number of bytes per second for all packets
|
|
matching the specified filter.
|
|
By default only one graph will be displayed showing number of packets per second.
|
|
|
|
The top part of the window contains the graphs and scales for the X and
|
|
Y axis. If the graph is too long to fit inside the window there is a
|
|
horizontal scrollbar below the drawing area that can scroll the graphs
|
|
to the left or the right. The horizontal axis displays the time into
|
|
the capture and the vertical axis will display the measured quantity at
|
|
that time.
|
|
|
|
Below the drawing area and the scrollbar are the controls. On the
|
|
bottom left there will be five similar sets of controls to control each
|
|
individual graph such as "Display:<button>" which button will toggle
|
|
that individual graph on/off. If <button> is ticked, the graph will be
|
|
displayed. "Color:<color>" which is just a button to show which color
|
|
will be used to draw that graph (color is only available in Gtk2
|
|
version) and finally "Filter:<filter-text>" which can be used to specify
|
|
a display filter for that particular graph.
|
|

If filter-text is empty then all packets will be used to calculate the
|
|
quantity for that graph. If filter-text is specified only those packets
|
|
that match that display filter will be considered in the calculation of
|
|
quantity.
|
|
|
|
To the right of the 5 graph controls there are four menus to control
|
|
global aspects of the draw area and graphs. The "Unit:" menu is used to
|
|
control what to measure; "packets/tick", "bytes/tick" or "advanced..."
|
|
|
|
packets/tick will measure the number of packets matching the (if
|
|
specified) display filter for the graph in each measurement interval.
|
|
|
|
bytes/tick will measure the total number of bytes in all packets matching
|
|
the (if specified) display filter for the graph in each measurement
|
|
interval.
|
|
|
|
advanced... see below
|
|
|
|
"Tick interval:" specifies what measurement intervals to use. The
|
|
default is 1 second and means that the data will be counted over 1
|
|
second intervals.
|
|
|
|
"Pixels per tick:" specifies how many pixels wide each measurement
|
|
interval will be in the drawing area. The default is 5 pixels per tick.
|
|
|
|
"Y-scale:" controls the max value for the y-axis. Default value is
|
|
"auto" which means that B<Wireshark> will try to adjust the maxvalue
|
|
automatically.
|
|
|
|
"advanced..." If Unit:advanced... is selected the window will display
|
|
two more controls for each of the five graphs. One control will be a
|
|
menu where the type of calculation can be selected from
|
|
SUM,COUNT,MAX,MIN,AVG and LOAD, and one control, textbox, where the name of a
|
|
single display filter field can be specified.
|
|
|
|
The following restrictions apply to type and field combinations:
|
|
|
|
SUM: available for all types of integers and will calculate the SUM of
|
|
all occurrences of this field in the measurement interval. Note that
|
|
some field can occur multiple times in the same packet and then all
|
|
instances will be summed up. Example: 'tcp.len' which will count the
|
|
amount of payload data transferred across TCP in each interval.
|
|
|
|
COUNT: available for all field types. This will COUNT the number of times
|
|
certain field occurs in each interval. Note that some fields
|
|
may occur multiple times in each packet and if that is the case
|
|
then each instance will be counted independently and COUNT
|
|
will be greater than the number of packets.
|
|
|
|
MAX: available for all integer and relative time fields. This will calculate
|
|
the max seen integer/time value seen for the field during the interval.
|
|
Example: 'smb.time' which will plot the maximum SMB response time.
|
|
|
|
MIN: available for all integer and relative time fields. This will calculate
|
|
the min seen integer/time value seen for the field during the interval.
|
|
Example: 'smb.time' which will plot the minimum SMB response time.
|
|
|
|
AVG: available for all integer and relative time fields.This will
|
|
calculate the average seen integer/time value seen for the field during
|
|
the interval. Example: 'smb.time' which will plot the average SMB
|
|
response time.
|
|
|
|
LOAD: available only for relative time fields (response times).
|
|
|
|
Example of advanced:
|
|
Display how NFS response time MAX/MIN/AVG changes over time:
|
|
|
|
Set first graph to:
|
|
|
|
filter:nfs&&rpc.time
|
|
Calc:MAX rpc.time
|
|
|
|
Set second graph to
|
|
|
|
filter:nfs&&rpc.time
|
|
Calc:AVG rpc.time
|
|
|
|
Set third graph to
|
|
|
|
filter:nfs&&rpc.time
|
|
Calc:MIN rpc.time
|
|
|
|
Example of advanced:
|
|
Display how the average packet size from host a.b.c.d changes over time.
|
|
|
|
Set first graph to
|
|
|
|
filter:ip.addr==a.b.c.d&&frame.pkt_len
|
|
Calc:AVG frame.pkt_len
|
|
|
|
LOAD:
|
|
The LOAD io-stat type is very different from anything you have ever seen
|
|
before! While the response times themselves as plotted by MIN,MAX,AVG are
|
|
indications on the Server load (which affects the Server response time),
|
|
the LOAD measurement measures the Client LOAD.
|
|
What this measures is how much workload the client generates,
|
|
i.e. how fast will the client issue new commands when the previous ones
|
|
completed.
|
|
i.e. the level of concurrency the client can maintain.
|
|
The higher the number, the more and faster is the client issuing new
|
|
commands. When the LOAD goes down, it may be due to client load making
|
|
the client slower in issuing new commands (there may be other reasons as
|
|
well, maybe the client just doesn't have any commands it wants to issue
|
|
right then).
|
|
|
|
Load is measured in concurrency/number of overlapping i/o and the value
|
|
1000 means there is a constant load of one i/o.
|
|
|
|
In each tick interval the amount of overlap is measured.
|
|
See the graph below containing three commands:
|
|
Below the graph are the LOAD values for each interval that would be calculated.

=item Statistics:Conversation List
|
|
|
|
This option will open a new window that displays a list of all
|
|
conversations between two endpoints. The list has one row for each
|
|
unique conversation and displays total number of packets/bytes seen as
|
|
well as number of packets/bytes in each direction.
|
|
|
|
By default the list is sorted according to the number of packets but by
|
|
clicking on the column header; it is possible to re-sort the list in
|
|
ascending or descending order by any column.
|
|
|
|
By first selecting a conversation by clicking on it and then using the
|
|
right mouse button (on those platforms that have a right
|
|
mouse button) wireshark will display a popup menu offering several different
|
|
filter operations to apply to the capture.
|

The I<Colors> page can be used to change the color of the text
|
|
displayed in the TCP stream window and for marked packets. To change a color,
|
|
simply select an attribute from the "Set:" menu and use the color selector to
|
|
get the desired color. The new text colors are displayed as a sample text.
|
|
|
|
=item Capture Preferences
|
|
|
|
The I<Capture> page lets you specify various parameters for capturing
|
|
live packet data; these are used the first time a capture is started.
|
|
|
|
The I<Interface:> combo box lets you specify the interface from which to
|
|
capture packet data, or the name of a FIFO from which to get the packet
|
|
data.
|
|
|
|
The I<Data link type:> option menu lets you, for some interfaces, select
|
|
the data link header you want to see on the packets you capture. For
|
|
example, in some OSes and with some versions of libpcap, you can choose,
|
|
on an 802.11 interface, whether the packets should appear as Ethernet
|
|
packets (with a fake Ethernet header) or as 802.11 packets.
|
|
|
|
The I<Limit each packet to ... bytes> check box lets you set the
|
|
snapshot length to use when capturing live data; turn on the check box,
|
|
and then set the number of bytes to use as the snapshot length.
|
|
|
|
The I<Filter:> text entry lets you set a capture filter expression to be
|
|
used when capturing.
|
|
|
|
If any of the environment variables SSH_CONNECTION, SSH_CLIENT,
|
|
REMOTEHOST, DISPLAY, or SESSIONNAME are set, Wireshark will create a
|
|
default capture filter that excludes traffic from the hosts and ports
|
|
defined in those variables.
|
|
|
|
The I<Capture packets in promiscuous mode> check box lets you specify
|
|
whether to put the interface in promiscuous mode when capturing.
|
|
|
|
The I<Update list of packets in real time> check box lets you specify
|
|
that the display should be updated as packets are seen.
|
|
|
|
The I<Automatic scrolling in live capture> check box lets you specify
|
|
whether, in an "Update list of packets in real time" capture, the packet
|
|
list pane should automatically scroll to show the most recently captured
|
|
packets.
|
|
|
|
=item Printing Preferences
|
|
|
|
The radio buttons at the top of the I<Printing> page allow you choose
|
|
between printing packets with the I<File:Print Packet> menu item as text
|
|
or PostScript, and sending the output directly to a command or saving it
|
|
to a file. The I<Command:> text entry box, on UNIX-compatible systems,
|
|
is the command to send files to (usually B<lpr>), and the I<File:> entry
|
|
box lets you enter the name of the file you wish to save to.
|
|
Additionally, you can select the I<File:> button to browse the file
|
|
system for a particular save file.
|
|
|
|
=item Name Resolution Preferences
|
|
|
|
The I<Enable MAC name resolution>, I<Enable network name resolution> and
|
|
I<Enable transport name resolution> check boxes let you specify whether
|
|
MAC addresses, network addresses, and transport-layer port numbers
|
|
should be translated to names.
|
|
|
|
The I<Enable concurrent DNS name resolution> allows Wireshark to send out
|
|
multiple name resolution requests and not wait for the result before
|
|
continuing dissection. This speeds up dissection with network name
|
|
resolution but initially may miss resolutions. The number of concurrent
|
|
requests can be set here as well.

=item Capture Options Dialog
|
|
|
|
The I<Capture Options Dialog> lets you specify various parameters for
|
|
capturing live packet data.
|
|
|
|
The I<Interface:> field lets you specify the interface from which to
|
|
capture packet data or a command from which to get the packet data via a
|
|
pipe.
|
|
|
|
The I<Link layer header type:> field lets you specify the interfaces link
|
|
layer header type. This field is usually disabled, as most interface have
|
|
only one header type.
|
|
|
|
The I<Capture packets in promiscuous mode> check box lets you specify
|
|
whether the interface should be put into promiscuous mode when
|
|
capturing.
|
|
|
|
The I<Limit each packet to ... bytes> check box and field lets you
|
|
specify a maximum number of bytes per packet to capture and save; if the
|
|
check box is not checked, the limit will be 262144 bytes.
|
|
|
|
The I<Capture Filter:> entry lets you specify the capture filter using a
|
|
tcpdump-style filter string as described above.
|
|
|
|
The I<File:> entry lets you specify the file into which captured packets
|
|
should be saved, as in the I<Printer Options> dialog above. If not
|
|
specified, the captured packets will be saved in a temporary file; you
|
|
can save those packets to a file with the I<File:Save As> menu item.
|
|
|
|
The I<Use multiple files> check box lets you specify that the capture
|
|
should be done in "multiple files" mode. This option is disabled, if the
|
|
I<Update list of packets in real time> option is checked.
|
|
|
|
The I<Next file every ... megabyte(s)> check box and fields lets
|
|
you specify that a switch to a next file should be done
|
|
if the specified filesize is reached. You can also select the appropriate
|
|
unit, but beware that the filesize has a maximum of 2 GiB.
|
|
The check box is forced to be checked, as "multiple files" mode requires a
|
|
file size to be specified.
|
|
|
|
The I<Next file every ... minute(s)> check box and fields lets
|
|
you specify that the switch to a next file should be done after the specified
|
|
time has elapsed, even if the specified capture size is not reached.
|
|
|
|
The I<Ring buffer with ... files> field lets you specify the number
|
|
of files of a ring buffer. This feature will capture into the first file
|
|
again, after the specified number of files have been used.
|
|
|
|
The I<Stop capture after ... files> field lets you specify the number
|
|
of capture files used, until the capture is stopped.
|
|
|
|
The I<Stop capture after ... packet(s)> check box and field let
|
|
you specify that Wireshark should stop capturing after having captured
|
|
some number of packets; if the check box is not checked, Wireshark will
|
|
not stop capturing at some fixed number of captured packets.
|
|
|
|
The I<Stop capture after ... megabyte(s)> check box and field lets
|
|
you specify that Wireshark should stop capturing after the file to which
|
|
captured packets are being saved grows as large as or larger than some
|
|
specified number of megabytes. If the check box is not checked, Wireshark
|
|
will not stop capturing at some capture file size (although the operating
|
|
system on which Wireshark is running, or the available disk space, may still
|
|
limit the maximum size of a capture file). This option is disabled, if
|
|
"multiple files" mode is used,
|
|
|
|
The I<Stop capture after ... second(s)> check box and field let you
|
|
specify that Wireshark should stop capturing after it has been capturing
|
|
for some number of seconds; if the check box is not checked, Wireshark
|
|
will not stop capturing after some fixed time has elapsed.
|
|
|
|
The I<Update list of packets in real time> check box lets you specify
|
|
whether the display should be updated as packets are captured and, if
|
|
you specify that, the I<Automatic scrolling in live capture> check box
|
|
lets you specify the packet list pane should automatically scroll to
|
|
show the most recently captured packets as new packets arrive.
|
|
|
|
The I<Enable MAC name resolution>, I<Enable network name resolution> and
|
|
I<Enable transport name resolution> check boxes let you specify whether
|
|
MAC addresses, network addresses, and transport-layer port numbers
|
|
should be translated to names.

=item About:Plugins
|
|
|
|
The I<Plugins> page lets you view the dissector plugin modules
|
|
available on your system.
|
|
|
|
The I<Plugins List> shows the name and version of each dissector plugin
|
|
module found on your system.
|
|
|
|
On Unix-compatible systems, the plugins are looked for in the following
|
|
directories: the F<lib/wireshark/plugins/$VERSION> directory under the
|
|
main installation directory (for example,
|
|
F</usr/local/lib/wireshark/plugins/$VERSION>), and then
|
|
F<$HOME/.wireshark/plugins>.
|
|
|
|
On Windows systems, the plugins are looked for in the following
|
|
directories: F<plugins\$VERSION> directory under the main installation
|
|
directory (for example, F<C:\Program Files\Wireshark\plugins\$VERSION>),
|
|
and then F<%APPDATA%\Wireshark\plugins\$VERSION> (or, if %APPDATA% isn't
|
|
defined, F<%USERPROFILE%\Application Data\Wireshark\plugins\$VERSION>).
|
|
|
|
$VERSION is the version number of the plugin interface, which
|
|
is typically the version number of Wireshark. Note that a dissector
|
|
plugin module may support more than one protocol; there is not
|
|
necessarily a one-to-one correspondence between dissector plugin modules
|
|
and protocols. Protocols supported by a dissector plugin module are
|
|
enabled and disabled using the I<Edit:Protocols> dialog box, just as
|
|
protocols built into Wireshark are.

=item Preferences
|
|
|
|
The F<preferences> files contain global (system-wide) and personal
|
|
preference settings. If the system-wide preference file exists, it is
|
|
read first, overriding the default settings. If the personal preferences
|
|
file exists, it is read next, overriding any previous values. Note: If
|
|
the command line flag B<-o> is used (possibly more than once), it will
|
|
in turn override values from the preferences files.
|
|
|
|
The preferences settings are in the form I<prefname>B<:>I<value>,
|
|
one per line,
|
|
where I<prefname> is the name of the preference
|
|
and I<value> is the value to
|
|
which it should be set; white space is allowed between B<:> and
|
|
I<value>. A preference setting can be continued on subsequent lines by
|
|
indenting the continuation lines with white space. A B<#> character
|
|
starts a comment that runs to the end of the line:
|
|
|
|
# Vertical scrollbars should be on right side?
|
|
# TRUE or FALSE (case-insensitive).
|
|
gui.scrollbar_on_right: TRUE
|
|
|
|
The global preferences file is looked for in the F<wireshark> directory
|
|
under the F<share> subdirectory of the main installation directory (for
|
|
example, F</usr/local/share/wireshark/preferences>) on UNIX-compatible
|
|
systems, and in the main installation directory (for example,
|
|
F<C:\Program Files\Wireshark\preferences>) on Windows systems.
|
|
|
|
The personal preferences file is looked for in
|
|
F<$XDG_CONFIG_HOME/wireshark/preferences>
|
|
(or, if F<$XDG_CONFIG_HOME/wireshark> does not exist while F<$HOME/.wireshark>
|
|
is present, F<$HOME/.wireshark/preferences>) on
|
|
UNIX-compatible systems and F<%APPDATA%\Wireshark\preferences> (or, if
|
|
%APPDATA% isn't defined, F<%USERPROFILE%\Application
|
|
Data\Wireshark\preferences>) on Windows systems.
|
|
|
|
Note: Whenever the preferences are saved by using the I<Save> button
|
|
in the I<Edit:Preferences> dialog box, your personal preferences file
|
|
will be overwritten with the new settings, destroying any comments and
|
|
unknown/obsolete settings that were in the file.
|
|
|
|
=item Recent
|
|
|
|
The F<recent> file contains personal settings (mostly GUI related) such
|
|
as the current B<Wireshark> window size. The file is saved at program exit and
|
|
read in at program start automatically. Note: The command line flag B<-o>
|
|
may be used to override settings from this file.
|
|
|
|
The settings in this file have the same format as in the F<preferences>
|
|
files, and the same directory as for the personal preferences file is
|
|
used.
|
|
|
|
Note: Whenever Wireshark is closed, your recent file
|
|
will be overwritten with the new settings, destroying any comments and
|
|
unknown/obsolete settings that were in the file.
|
|
|
|
=item Disabled (Enabled) Protocols
|
|
|
|
The F<disabled_protos> files contain system-wide and personal lists of
|
|
protocols that have been disabled, so that their dissectors are never
|
|
called. The files contain protocol names, one per line, where the
|
|
protocol name is the same name that would be used in a display filter
|
|
for the protocol:
|
|
|
|
http
|
|
tcp # a comment
|
|
|
|
If a protocol is listed in the global F<disabled_protos> file, it is not
|
|
displayed in the I<Analyze:Enabled Protocols> dialog box, and so cannot
|
|
be enabled by the user.
|
|
|
|
The global F<disabled_protos> file uses the same directory as the global
|
|
preferences file.
|
|
|
|
The personal F<disabled_protos> file uses the same directory as the
|
|
personal preferences file.
|
|
|
|
Note: Whenever the disabled protocols list is saved by using the I<Save>
|
|
button in the I<Analyze:Enabled Protocols> dialog box, your personal
|
|
disabled protocols file will be overwritten with the new settings,
|
|
destroying any comments that were in the file.
|
|
|
|
=item Name Resolution (hosts)
|
|
|
|
If the personal F<hosts> file exists, it is
|
|
used to resolve IPv4 and IPv6 addresses before any other
|
|
attempts are made to resolve them. The file has the standard F<hosts>
|
|
file syntax; each line contains one IP address and name, separated by
|
|
whitespace. The same directory as for the personal preferences file is used.
|
|
|
|
Capture filter name resolution is handled by libpcap on UNIX-compatible
|
|
systems and WinPcap on Windows. As such the Wireshark personal F<hosts> file
|
|
will not be consulted for capture filter name resolution.
|
|
|
|
=item Name Resolution (subnets)
|
|
|
|
If an IPv4 address cannot be translated via name resolution (no exact
|
|
match is found) then a partial match is attempted via the F<subnets> file.
|
|
Both the global F<subnets> file and personal F<subnets> files are used
|
|
if they exist.
|
|
|
|
Each line of this file consists of an IPv4 address, a subnet mask length
|
|
separated only by a / and a name separated by whitespace. While the address
|
|
must be a full IPv4 address, any values beyond the mask length are subsequently
|
|
ignored.
|
|
|
|
An example is:
|
|
|
|
# Comments must be prepended by the # sign!
|
|
192.168.0.0/24 ws_test_network
|
|
|
|
A partially matched name will be printed as "subnet-name.remaining-address".
|
|
For example, "192.168.0.1" under the subnet above would be printed as
|
|
"ws_test_network.1"; if the mask length above had been 16 rather than 24, the
|
|
printed address would be ``ws_test_network.0.1".
|
|
|
|
=item Name Resolution (ethers)
|
|
|
|
The F<ethers> files are consulted to correlate 6-byte hardware addresses to
|
|
names. First the personal F<ethers> file is tried and if an address is not
|
|
found there the global F<ethers> file is tried next.
|
|
|
|
Each line contains one hardware address and name, separated by
|
|
whitespace. The digits of the hardware address are separated by colons
|
|
(:), dashes (-) or periods (.). The same separator character must be
|
|
used consistently in an address. The following three lines are valid
|
|
lines of an F<ethers> file:
|
|
|
|
ff:ff:ff:ff:ff:ff Broadcast
|
|
c0-00-ff-ff-ff-ff TR_broadcast
|
|
00.00.00.00.00.00 Zero_broadcast
|
|
|
|
The global F<ethers> file is looked for in the F</etc> directory on
|
|
UNIX-compatible systems, and in the main installation directory (for
|
|
example, F<C:\Program Files\Wireshark>) on Windows systems.
|
|
|
|
The personal F<ethers> file is looked for in the same directory as the personal
|
|
preferences file.
|
|
|
|
Capture filter name resolution is handled by libpcap on UNIX-compatible
|
|
systems and WinPcap on Windows. As such the Wireshark personal F<ethers> file
|
|
will not be consulted for capture filter name resolution.
|
|
|
|
=item Name Resolution (manuf)
|
|
|
|
The F<manuf> file is used to match the 3-byte vendor portion of a 6-byte
|
|
hardware address with the manufacturer's name; it can also contain well-known
|
|
MAC addresses and address ranges specified with a netmask. The format of the
|
|
file is the same as the F<ethers> files, except that entries such as:
|
|
|
|
00:00:0C Cisco
|
|
|
|
can be provided, with the 3-byte OUI and the name for a vendor, and
|
|
entries such as:
|
|
|
|
00-00-0C-07-AC/40 All-HSRP-routers
|
|
|
|
can be specified, with a MAC address and a mask indicating how many bits
|
|
of the address must match. The above entry, for example, has 40
|
|
significant bits, or 5 bytes, and would match addresses from
|
|
00-00-0C-07-AC-00 through 00-00-0C-07-AC-FF. The mask need not be a
|
|
multiple of 8.
|
|
|
|
The F<manuf> file is looked for in the same directory as the global
|
|
preferences file.
|
|
|
|
=item Name Resolution (services)
|
|
|
|
The F<services> file is used to translate port numbers into names.
|
|
Both the global F<services> file and personal F<services> files are used
|
|
if they exist.
|
|
|
|
The file has the standard F<services> file syntax; each line contains one
|
|
(service) name and one transport identifier separated by white space. The
|
|
transport identifier includes one port number and one transport protocol name
|
|
(typically tcp, udp, or sctp) separated by a /.
|
|
|
|
An example is:
|
|
|
|
mydns 5045/udp # My own Domain Name Server
|
|
mydns 5045/tcp # My own Domain Name Server
|
|
|
|
=item Name Resolution (ipxnets)
|
|
|
|
The F<ipxnets> files are used to correlate 4-byte IPX network numbers to
|
|
names. First the global F<ipxnets> file is tried and if that address is not
|
|
found there the personal one is tried next.
|
|
|
|
The format is the same as the F<ethers>
|
|
file, except that each address is four bytes instead of six.
|
|
Additionally, the address can be represented as a single hexadecimal
|
|
number, as is more common in the IPX world, rather than four hex octets.
|
|
For example, these four lines are valid lines of an F<ipxnets> file:
|
|
|
|
C0.A8.2C.00 HR
|
|
c0-a8-1c-00 CEO
|
|
00:00:BE:EF IT_Server1
|
|
110f FileServer3
|
|
|
|
The global F<ipxnets> file is looked for in the F</etc> directory on
|
|
UNIX-compatible systems, and in the main installation directory (for
|
|
example, F<C:\Program Files\Wireshark>) on Windows systems.
|
|
|
|
The personal F<ipxnets> file is looked for in the same directory as the
|
|
personal preferences file.
|
|
|
|
=item Capture Filters
|
|
|
|
The F<cfilters> files contain system-wide and personal capture filters.
|
|
Each line contains one filter, starting with the string displayed in the
|
|
dialog box in quotation marks, followed by the filter string itself:
|
|
|
|
"HTTP" port 80
|
|
"DCERPC" port 135
|
|
|
|
The global F<cfilters> file uses the same directory as the
|
|
global preferences file.
|
|
|
|
The personal F<cfilters> file uses the same directory as the personal
|
|
preferences file. It is written through the Capture:Capture Filters
|
|
dialog.
|
|
|
|
If the global F<cfilters> file exists, it is used only if the personal
|
|
F<cfilters> file does not exist; global and personal capture filters are
|
|
not merged.
|
|
|
|
=item Display Filters
|
|
|
|
The F<dfilters> files contain system-wide and personal display filters.
|
|
Each line contains one filter, starting with the string displayed in the
|
|
dialog box in quotation marks, followed by the filter string itself:
|
|
|
|
"HTTP" http
|
|
"DCERPC" dcerpc
|
|
|
|
The global F<dfilters> file uses the same directory as the
|
|
global preferences file.
|
|
|
|
The personal F<dfilters> file uses the same directory as the
|
|
personal preferences file. It is written through the Analyze:Display
|
|
Filters dialog.
|
|
|
|
If the global F<dfilters> file exists, it is used only if the personal
|
|
F<dfilters> file does not exist; global and personal display filters are
|
|
not merged.
|
|
|
|
=item Color Filters (Coloring Rules)
|
|
|
|
The F<colorfilters> files contain system-wide and personal color filters.
|
|
Each line contains one filter, starting with the string displayed in the
|
|
dialog box, followed by the corresponding display filter. Then the
|
|
background and foreground colors are appended:
|
|
|
|
# a comment
|
|
@tcp@tcp@[59345,58980,65534][0,0,0]
|
|
@udp@udp@[28834,57427,65533][0,0,0]
|
|
|
|
The global F<colorfilters> file uses the same directory as the
|
|
global preferences file.
|
|
|
|
The personal F<colorfilters> file uses the same directory as the
|
|
personal preferences file. It is written through the View:Coloring Rules
|
|
dialog.
|
|
|
|
If the global F<colorfilters> file exists, it is used only if the personal
|
|
F<colorfilters> file does not exist; global and personal color filters are
|
|
not merged.
|
|
|
|
=item GTK rc files
|
|
|
|
The F<gtkrc> files contain system-wide and personal GTK theme settings.
|
|
|
|
The global F<gtkrc> file uses the same directory as the
|
|
global preferences file.
|
|
|
|
The personal F<gtkrc> file uses the same directory as the personal
|
|
preferences file.
|
|

=head1 ENVIRONMENT VARIABLES
|
|
|
|
=over 4
|
|
|
|
=item WIRESHARK_APPDATA
|
|
|
|
On Windows, Wireshark normally stores all application data in %APPDATA% or
|
|
%USERPROFILE%. You can override the default location by exporting this
|
|
environment variable to specify an alternate location.
|
|
|
|
=item WIRESHARK_DEBUG_WMEM_OVERRIDE
|
|
|
|
Setting this environment variable forces the wmem framework to use the
|
|
specified allocator backend for *all* allocations, regardless of which
|
|
backend is normally specified by the code. This is mainly useful to developers
|
|
when testing or debugging. See I<README.wmem> in the source distribution for
|
|
details.
|
|
|
|
=item WIRESHARK_RUN_FROM_BUILD_DIRECTORY
|
|
|
|
This environment variable causes the plugins and other data files to be loaded
|
|
from the build directory (where the program was compiled) rather than from the
|
|
standard locations. It has no effect when the program in question is running
|
|
with root (or setuid) permissions on *NIX.
|
|
|
|
=item WIRESHARK_DATA_DIR
|
|
|
|
This environment variable causes the various data files to be loaded from
|
|
a directory other than the standard locations. It has no effect when the
|
|
program in question is running with root (or setuid) permissions on *NIX.
|
|
|
|
=item ERF_RECORDS_TO_CHECK
|
|
|
|
This environment variable controls the number of ERF records checked when
|
|
deciding if a file really is in the ERF format. Setting this environment
|
|
variable a number higher than the default (20) would make false positives
|
|
less likely.
|
|
|
|
=item IPFIX_RECORDS_TO_CHECK
|
|
|
|
This environment variable controls the number of IPFIX records checked when
|
|
deciding if a file really is in the IPFIX format. Setting this environment
|
|
variable a number higher than the default (20) would make false positives
|
|
less likely.
|
|
|
|
=item WIRESHARK_ABORT_ON_DISSECTOR_BUG
|
|
|
|
If this environment variable is set, B<Wireshark> will call abort(3)
|
|
when a dissector bug is encountered. abort(3) will cause the program to
|
|
exit abnormally; if you are running B<Wireshark> in a debugger, it
|
|
should halt in the debugger and allow inspection of the process, and, if
|
|
you are not running it in a debugger, it will, on some OSes, assuming
|
|
your environment is configured correctly, generate a core dump file.
|
|
This can be useful to developers attempting to troubleshoot a problem
|
|
with a protocol dissector.
|
|
|
|
=item WIRESHARK_ABORT_ON_TOO_MANY_ITEMS
|
|
|
|
If this environment variable is set, B<Wireshark> will call abort(3)
|
|
if a dissector tries to add too many items to a tree (generally this
|
|
is an indication of the dissector not breaking out of a loop soon enough).
|
|
abort(3) will cause the program to exit abnormally; if you are running
|
|
B<Wireshark> in a debugger, it should halt in the debugger and allow
|
|
inspection of the process, and, if you are not running it in a debugger,
|
|
it will, on some OSes, assuming your environment is configured correctly,
|
|
generate a core dump file. This can be useful to developers attempting to
|
|
troubleshoot a problem with a protocol dissector.
|
|
|
|
=item WIRESHARK_QUIT_AFTER_CAPTURE
|
|
|
|
Cause B<Wireshark> to exit after the end of the capture session. This
|
|
doesn't automatically start a capture; you must still use B<-k> to do
|
|
that. You must also specify an autostop condition, e.g. B<-c> or B<-a
|
|
duration:...>. This means that you will not be able to see the results
|
|
of the capture after it stops; it's primarily useful for testing.
