DESCRIPTION¶

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. Wireshark's native capture file format is libpcap format, which is also the format used by tcpdump and various other tools. Wireshark can read / import the following file formats:

•

There is no need to tell Wireshark what type of file you are reading; it will determine the file type by itself. Wireshark is also capable of reading any of these file formats if they are compressed using gzip. Wireshark recognizes this directly from the file; the '.gz' extension is not required for this purpose. Like other protocol analyzers, 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, 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 Wireshark are very powerful; more fields are filterable in Wireshark than in other protocol analyzers, and the syntax you can use to create your filters is richer. As 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, 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 -r option or can be specified as a command-line argument.

OPTIONS¶

Most users will want to start Wireshark without options and configure it from the menus instead. Those users may just skip this section.

-a <capture autostop condition>

Specify a criterion that specifies when Wireshark is to stop writing to a capture file. The criterion is of the form test :value, where test is one of:

 

duration:value Stop writing to a capture file after value seconds have elapsed.

 

filesize:value Stop writing to a capture file after it reaches a size of value kilobytes (where a kilobyte is 1024 bytes). 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.

 

files:value Stop writing to capture files after value number of files were written.

-b <capture ring buffer option>

Cause Wireshark to run in "multiple files" mode. In "multiple files" mode, Wireshark will write to several capture files. When the first capture file fills up, Wireshark will switch writing to the next file and so on.

 

The created filenames are based on the filename given with the -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 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 Wireshark will discard the data in the first file and start writing to that file and so on. If the 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 key:value, where key is one of:

 

duration:value switch to the next file after value seconds have elapsed, even if the current file is not completely filled up.

 

filesize:value switch to the next file after it reaches a size of value kilobytes (where a kilobyte is 1024 bytes).

 

files:value begin again with the first file after 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 files criterion requires either duration or filesize to be specified to control when to go to the next file. It should be noted that each -b parameter takes exactly one criterion; to specify two criterion, each must be preceded by the -b option.

 

Example: -b filesize:1024 -b files:5 results in a ring buffer of five files of size one megabyte.

-B <capture buffer size>

Set capture buffer size (in MB, default is 1MB). This is used by the 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 Tshark attempts to set the buffer size to 1MB 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 -i option, it sets the default capture buffer size. If used after an -i option, it sets the capture buffer size for the interface specified by the last -i option occurring before this option. If the capture buffer size is not set specifically, the default capture buffer size is used if provided.

-c <capture packet count>

Set the maximum number of packets to read when capturing live data.

-C <configuration profile>

Start with the given configuration profile.

-d <display filter>

Start with the given display filter.

-D

Print a list of the interfaces on which 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 -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 (e.g., Windows systems, or UNIX systems lacking ifconfig -a); the number can be useful on Windows 2000 and later systems, where the interface name is a somewhat complex string.

 

Note that "can capture" means that 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 Wireshark is run with the -D flag and is not run from such an account, it will not list any interfaces.

--display=<X display to use>

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.

-f <capture filter>

Set the capture filter expression.

 

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

-g <packet number>

After reading in a capture file using the -r flag, go to the given packet number.

-h

Print the version and options and exit.

-H

Hide the capture info dialog during live packet capture.

-i <capture interface>|-

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 " wireshark -D" (described above); a number, as reported by " wireshark -D", can also be used. If you're using UNIX, " netstat -i" or "ifconfig -a" might also work to list interface names, although not all versions of UNIX support the -a flag to ifconfig.

 

If no interface is specified, 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, 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\.\ pipename''. Data read from pipes must be in standard libpcap format.

 

This option can occur multiple times. When capturing from multiple interfaces, the capture file will be saved in pcap-ng format.

-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 -i option, it enables the monitor mode for all interfaces. If used after an -i option, it enables the monitor mode for the interface specified by the last -i option occurring before this option.

-j

Use after -J to change the behavior when no exact match is found for the filter. With this option select the first packet before.

-J <jump filter>

After reading in a capture file using the -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.

-k

Start the capture session immediately. If the -i flag was specified, the capture uses the specified interface. Otherwise, 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, Wireshark reports an error and doesn't start the capture.

-K <keytab>

Load kerberos crypto keys from the specified keytab file. This option can be used multiple times to load keys from several files.

 

Example: -K krb5.keytab

-l

Turn on automatic scrolling if the packet display is being updated automatically as packets arrive during a capture (as specified by the -S flag).

-L

List the data link types supported by the interface and exit.

-m <font>

Set the name of the font used by Wireshark for most text. Wireshark will construct the name of the bold font used for the data in the byte view pane that corresponds to the field selected in the packet details pane from the name of the main text font.

-n

Disable network object name resolution (such as hostname, TCP and UDP port names), the -N flag might override this one.

-N <name resolving flags>

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 -n if both -N and -n are present. If both -N and -n flags are not present, all name resolutions are turned on.

 

The argument is a string that may contain the letters:

 

m to enable MAC address resolution

 

n to enable network address resolution

 

t to enable transport-layer port number resolution

 

C to enable concurrent (asynchronous) DNS lookups

-o <preference/recent setting>

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 prefname:value, where prefname is the name of the preference/recent value (which is the same name that would appear in the preference/recent file), and value is the value to which it should be set. Since Ethereal 0.10.12, the recent settings replaces the formerly used -B, -P and -T flags to manipulate the GUI dimensions.

 

If prefname is "uat", you can override settings in various user access tables using the form uat :uat filename:uat record. uat filename must be the name of a UAT file, e.g. user_dlts. 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

-p

Don't put the interface into promiscuous mode. Note that the interface might be in promiscuous mode for some other reason; hence, -p cannot be used to ensure that the only traffic that is captured is traffic sent to or from the machine on which 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 -i option, no interface will be put into the promiscuous mode. If used after an -i option, the interface specified by the last -i option occurring before this option will not be put into the promiscuous mode.

-P <path setting>

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 key:path, where key is one of:

 

persconf:path path of personal configuration files, like the preferences files.

 

persdata: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.

-r <infile>

Read packet data from 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 -i -

-R <read (display) filter>

When reading a capture file specified with the -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.

-s <capture snaplen>

Set the default snapshot length to use when capturing live data. No more than snaplen bytes of each network packet will be read into memory, or saved to disk. A value of 0 specifies a snapshot length of 65535, 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 -i option, it sets the default snapshot length. If used after an -i option, it sets the snapshot length for the interface specified by the last -i option occurring before this option. If the snapshot length is not set specifically, the default snapshot length is used if provided.

-S

Automatically update the packet display as packets are coming in.

-t ad|a|r|d|dd|e

Set the format of the packet timestamp displayed in the packet list window. The format can be one of:

 

ad absolute with date: The absolute date and time is the actual time and date the packet was captured

 

a absolute: The absolute time is the actual time the packet was captured, with no date displayed

 

r relative: The relative time is the time elapsed between the first packet and the current packet

 

d delta: The delta time is the time since the previous packet was captured

 

dd delta_displayed: The delta_displayed time is the time since the previous displayed packet was captured

 

e epoch: The time in seconds since epoch (Jan 1, 1970 00:00:00)

 

The default format is relative.

-v

Print the version and exit.

-w <outfile>

Set the default capture file name.

-X <eXtension options>

Specify an option to be passed to an Wireshark module. The eXtension option is in the form extension_key:value, where extension_key can be:

 

lua_script:lua_script_filename tells Wireshark to load the given script in addition to the default Lua scripts.

 

stdin_descr:description tells Wireshark to use the given description when capturing from standard input ( -i -).

-y <capture link type>

If a capture is started from the command line with -k, set the data link type to use while capturing packets. The values reported by -L are the values that can be used.

 

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

-z <statistics>

Get Wireshark to collect various types of statistics and display the result in a window that updates in semi-real time.

 

Currently implemented statistics are:

MENU ITEMS¶

File:Open

File:Open Recent

File:Merge

Merge another capture file to the currently loaded one. The File:Merge dialog box allows the merge "Prepended", "Chronologically" or "Appended", relative to the already loaded one.

File:Close

Open or close a capture file. The 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 matching the filter are discarded. The File:Open Recent is a submenu and will show a list of previously opened files.

File:Save

File:Save As

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 a list of file formats in which at particular capture, or the packets currently displayed from that capture, can be saved), a file format in which to save it.

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.

File:File Set:Next File

File:File Set:Previous File

If the currently loaded file is part of a file set (see above), open the next / previous file in that set.

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.

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 Edit:Preferences menu item, or in the dialog box popped up by this menu item.

File:Quit

Exit the application.

Edit:Copy:Description

Copies the description of the selected field in the protocol tree to the clipboard.

Edit:Copy:Fieldname

Copies the fieldname of the selected field in the protocol tree to the clipboard.

Edit:Copy:Value

Copies the value of the selected field in the protocol tree to the clipboard.

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.

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.

Edit:Find Next

Edit:Find Previous

Search forward / backward for a packet matching the filter from the previous search, starting with the currently selected packet (or the most recently selected packet, if no packet is selected).

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 Edit:Find Packet dialog can be used to find the next or previous marked packet.

Edit:Find Next Mark

Edit:Find Previous Mark

Find next/previous marked packet.

Edit:Mark All Packets

Edit:Unmark All Packets

Mark / Unmark all packets that are currently displayed.

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 be reset at every Time Reference packet.

Edit:Time Reference:Find Next

Edit:Time Reference:Find Previous

Search forward / backward for a time referenced packet.

Edit:Configuration Profiles

Manage configuration profiles to be able to use more than one set of preferences and configurations.

Edit:Preferences

Set the GUI, capture, printing and protocol options (see Preferences dialog below).

View:Main Toolbar

View:Filter Toolbar

View:Statusbar

Show or hide the main window controls.

View:Packet List

View:Packet Details

View:Packet Bytes

Show or hide the main window panes.

View:Time Display Format

Set the format of the packet timestamp displayed in the packet list window.

View:Name Resolution:Resolve Name

Try to resolve a name for the currently selected item.

View:Name Resolution:Enable for ... Layer

Enable or disable translation of addresses to names in the display.

View:Colorize Packet List

Enable or disable the coloring rules. Disabling will improve performance.

View:Auto Scroll in Live Capture

Enable or disable the automatic scrolling of the packet list while a live capture is in progress.

View:Zoom In

View:Zoom Out

Zoom into / out of the main window data (by changing the font size).

View:Normal Size

Reset the zoom factor of zoom in / zoom out back to normal font size.

View:Resize All Columns

Resize all columns to best fit the current packet display.

View:Expand Subtrees

Expands the currently selected item and it's subtrees in the packet details.

View:Expand All

View:Collapse All

Expand / Collapse all branches of the packet details.

View:Colorize Conversation

Select color for a conversation.

View:Reset Coloring 1-10

Reset Color for a conversation.

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.

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.

View:Reload

Reload a capture file. Same as File:Close and File:Open the same file again.

Go:Back

Go back in previously visited packets history.

Go:Forward

Go forward in previously visited packets history.

Go:Go To Packet

Go to a particular numbered packet.

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.

Go:Previous Packet

Go:Next Packet

Go:First Packet

Go:Last Packet

Go to the previous / next / first / last packet in the capture.

Go:Previous Packet In Conversation

Go:Next Packet In Conversation

Go to the previous / next packet of the conversation (TCP, UDP or IP)

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!

Capture:Options

Initiate a live packet capture (see 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 Wireshark. Otherwise, the default TMPDIR location is system-dependent, but is likely either /var/tmp or /tmp.

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.

Capture:Stop

Stop a running live capture.

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.

Capture:Capture Filters

Edit the saved list of capture filters, allowing filters to be added, changed, or deleted.

Analyze:Display Filters

Edit the saved list of display filters, allowing filters to be added, changed, or deleted.

Analyze:Display Filter Macros

Create shortcuts for complex macros

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 Selected option creates a display filter that tests for a match of the data; the Not Selected option creates a display filter that tests for a non-match of the data. The And Selected, Or Selected, And Not Selected, and 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.

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.

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.

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.

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.

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:

Analyze:Follow UDP Stream

Analyze:Follow SSL Stream

(Similar to Analyze:Follow TCP Stream)

Analyze:Expert Info

Analyze:Expert Info Composite

(Kind of) a log of anomalies found by Wireshark in a capture file.

Analyze:Conversation Filter

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.

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) ended in a particular protocol. In the table, they are listed under "End Packets" and "End Bytes".

Statistics:Conversations

Lists of conversations; selectable by protocol. See Statistics:Conversation List below.

Statistics:End Points

List of End Point Addresses by protocol with packets/bytes/.... counts.

Statistics:Packet Lengths

Grouped counts of packet lengths (0-19 bytes, 20-39 bytes, ...)

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 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.

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.

 

These statistics windows can also be invoked from the Wireshark command line using the -z conv argument.

Telephony:ITU-T H.225

Count ITU-T H.225 messages and their reasons. In the first column you get a list of H.225 messages and H.225 message reasons, which occur in the current capture file. The number of occurrences of each message or reason will be displayed in the second column. This window opened will update in semi-real time to reflect changes when doing live captures or when reading new capture files into Wireshark.

 

You can apply an optional filter string in a dialog box, before starting the counter. The statistics will only be calculated on those calls matching that filter.

Telephony:SIP

Activate a counter for SIP messages. You will get the number of occurrences of each SIP Method and of each SIP Status-Code. Additionally you also get the number of resent SIP Messages (only for SIP over UDP).

 

This window opened will update in semi-real time to reflect changes when doing live captures or when reading new capture files into Wireshark.

 

You can apply an optional filter string in a dialog box, before starting the counter. The statistics will only be calculated on those calls matching that filter.

WINDOWS¶

Main Window

The main window contains the usual things like the menu, some toolbars, the main area and a statusbar. The main area is split into three panes, you can resize each pane using a "thumb" at the right end of each divider line.

 

The main window is much more flexible than before. The layout of the main window can be customized by the Layout page in the dialog box popped up by Edit:Preferences, the following will describe the layout with the default settings.

Preferences

The Preferences dialog lets you control various personal preferences for the behavior of Wireshark.

Edit Capture Filter List

Edit Display Filter List

Capture Filter

Display Filter

Read Filter

Search Filter

The Edit Capture Filter List dialog lets you create, modify, and delete capture filters, and the Edit Display Filter List dialog lets you create, modify, and delete display filters.

 

The Capture Filter dialog lets you do all of the editing operations listed, and also lets you choose or construct a filter to be used when capturing packets.

 

The Display Filter dialog lets you do all of the editing operations listed, and also lets you choose or construct a filter to be used to filter the current capture being viewed.

 

The Read Filter dialog lets you do all of the editing operations listed, and also lets you choose or construct a filter to be used to as a read filter for a capture file you open.

 

The Search Filter dialog lets you do all of the editing operations listed, and also lets you choose or construct a filter expression to be used in a find operation.

 

In all of those dialogs, the Filter name entry specifies a descriptive name for a filter, e.g. Web and DNS traffic. The Filter string entry is the text that actually describes the filtering action to take, as described above.The dialog buttons perform the following actions:

The Color Filters Dialog

This dialog displays a list of color filters and allows it to be modified.

Capture Options

The Capture Options dialog lets you specify various parameters for capturing live packet data.

 

The 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 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 Capture packets in promiscuous mode check box lets you specify whether the interface should be put into promiscuous mode when capturing.

 

The 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 65535 bytes.

 

The Capture Filter: entry lets you specify the capture filter using a tcpdump-style filter string as described above.

 

The File: entry lets you specify the file into which captured packets should be saved, as in the 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 File:Save As menu item.

 

The Use multiple files check box lets you specify that the capture should be done in "multiple files" mode. This option is disabled, if the Update list of packets in real time option is checked.

 

The 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 GB. The check box is forced to be checked, as "multiple files" mode requires a file size to be specified.

 

The 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 Ring buffer with ... files field lets you specify the number of files of a ring buffer. This feature will capture into to the first file again, after the specified amount of files were used.

 

The Stop capture after ... files field lets you specify the number of capture files used, until the capture is stopped.

 

The 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 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 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 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 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 Enable MAC name resolution, Enable network name resolution and Enable transport name resolution check boxes let you specify whether MAC addresses, network addresses, and transport-layer port numbers should be translated to names.

About

The About dialog lets you view various information about Wireshark.

About:Wireshark

The Wireshark page lets you view general information about Wireshark, like the installed version, licensing information and such.

About:Authors

The Authors page shows the author and all contributors.

About:Folders

The Folders page lets you view the directory names where Wireshark is searching it's various configuration and other files.

About:Plugins

The Plugins page lets you view the dissector plugin modules available on your system.

 

The 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 lib/wireshark/plugins/$VERSION directory under the main installation directory (for example, /usr/local/lib/wireshark/plugins/$VERSION), and then $HOME /.wireshark/plugins.

 

On Windows systems, the plugins are looked for in the following directories: plugins\$VERSION directory under the main installation directory (for example, C:\Program Files\Wireshark\plugins\$VERSION), and then %APPDATA%\Wireshark\plugins\$VERSION (or, if %APPDATA% isn't defined, %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 Edit:Protocols dialog box, just as protocols built into Wireshark are.

CAPTURE FILTER SYNTAX¶

See the manual page of pcap-filter(7) or, if that doesn't exist, tcpdump(8), or, if that doesn't exist, <http://wiki.wireshark.org/CaptureFilters>.

DISPLAY FILTER SYNTAX¶

For a complete table of protocol and protocol fields that are filterable in Wireshark see the wireshark-filter(4) manual page.

FILES¶

These files contains various Wireshark configuration settings.

Preferences

The 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 -o is used (possibly more than once), it will in turn override values from the preferences files.

 

The preferences settings are in the form prefname:value, one per line, where prefname is the name of the preference and value is the value to which it should be set; white space is allowed between : and value. A preference setting can be continued on subsequent lines by indenting the continuation lines with white space. A # 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 wireshark directory under the share subdirectory of the main installation directory (for example, /usr/local/share/wireshark/preferences) on UNIX-compatible systems, and in the main installation directory (for example, C:\Program Files\Wireshark\preferences) on Windows systems.

 

The personal preferences file is looked for in $HOME/.wireshark/preferences on UNIX-compatible systems and %APPDATA%\Wireshark\preferences (or, if %APPDATA% isn't defined, %USERPROFILE%\Application Data\Wireshark\preferences) on Windows systems.

 

Note: Whenever the preferences are saved by using the Save button in the 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.

Recent

The recent file contains personal settings (mostly GUI related) such as the current Wireshark window size. The file is saved at program exit and read in at program start automatically. Note: The command line flag -o may be used to override settings from this file.

 

The settings in this file have the same format as in the 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.

Disabled (Enabled) Protocols

The 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 disabled_protos file, it is not displayed in the Analyze:Enabled Protocols dialog box, and so cannot be enabled by the user.

 

The global disabled_protos file uses the same directory as the global preferences file.

 

The personal disabled_protos file uses the same directory as the personal preferences file.

 

Note: Whenever the disabled protocols list is saved by using the Save button in the 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.

Name Resolution (hosts)

If the personal 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 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 hosts file will not be consulted for capture filter name resolution.

Name Resolution (ethers)

The ethers files are consulted to correlate 6-byte hardware addresses to names. First the personal ethers file is tried and if an address is not found there the global 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 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 ethers file is looked for in the /etc directory on UNIX-compatible systems, and in the main installation directory (for example, C:\Program Files\Wireshark) on Windows systems.

 

The personal 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 ethers file will not be consulted for capture filter name resolution.

Name Resolution (manuf)

The 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 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 manuf file is looked for in the same directory as the global preferences file.

Name Resolution (ipxnets)

The ipxnets files are used to correlate 4-byte IPX network numbers to names. First the global 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 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 ipxnets file:

 

  C0.A8.2C.00              HR
  c0-a8-1c-00              CEO
  00:00:BE:EF              IT_Server1
  110f                     FileServer3
    

 

The global ipxnets file is looked for in the /etc directory on UNIX-compatible systems, and in the main installation directory (for example, C:\Program Files\Wireshark) on Windows systems.

 

The personal ipxnets file is looked for in the same directory as the personal preferences file.

Capture Filters

The 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 cfilters file uses the same directory as the global preferences file.

 

The personal cfilters file uses the same directory as the personal preferences file. It is written through the Capture:Capture Filters dialog.

 

If the global cfilters file exists, it is used only if the personal cfilters file does not exist; global and personal capture filters are not merged.

Display Filters

The 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 dfilters file uses the same directory as the global preferences file.

 

The personal dfilters file uses the same directory as the personal preferences file. It is written through the Analyze:Display Filters dialog.

 

If the global dfilters file exists, it is used only if the personal dfilters file does not exist; global and personal display filters are not merged.

Color Filters (Coloring Rules)

The 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 colorfilters file uses the same directory as the global preferences file.

 

The personal colorfilters file uses the same directory as the personal preferences file. It is written through the View:Coloring Rules dialog.

 

If the global colorfilters file exists, it is used only if the personal colorfilters file does not exist; global and personal color filters are not merged.

GTK rc files

The gtkrc files contain system-wide and personal GTK theme settings.

 

The global gtkrc file uses the same directory as the global preferences file.

 

The personal gtkrc file uses the same directory as the personal preferences file.

Plugins

See above in the description of the About:Plugins page.

ENVIRONMENT VARIABLES¶

WIRESHARK_DEBUG_EP_NO_CHUNKS

Normally per-packet memory is allocated in large "chunks." This behavior doesn't work well with debugging tools such as Valgrind or ElectricFence. Export this environment variable to force individual allocations. Note: disabling chunks also disables canaries (see below).

WIRESHARK_DEBUG_SE_NO_CHUNKS

Normally per-file memory is allocated in large "chunks." This behavior doesn't work well with debugging tools such as Valgrind or ElectricFence. Export this environment variable to force individual allocations. Note: disabling chunks also disables canaries (see below).

WIRESHARK_DEBUG_EP_NO_CANARY

Normally per-packet memory allocations are separated by "canaries" which allow detection of memory overruns. This comes at the expense of some extra memory usage. Exporting this environment variable disables these canaries.

WIRESHARK_DEBUG_SE_USE_CANARY

Exporting this environment variable causes per-file memory allocations to be protected with "canaries" which allow for detection of memory overruns. This comes at the expense of significant extra memory usage.

WIRESHARK_DEBUG_SCRUB_MEMORY

If this environment variable is set, the contents of per-packet and per-file memory is initialized to 0xBADDCAFE when the memory is allocated and is reset to 0xDEADBEEF when the memory is freed. This functionality is useful mainly to developers looking for bugs in the way memory is handled.

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.

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.

WIRESHARK_PYTHON_DIR

This environment variable points to an alternate location for Python. It has no effect when the program in question is running with root (or setuid) permissions on *NIX.

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.

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.

WIRESHARK_ABORT_ON_DISSECTOR_BUG

If this environment variable is set, Wireshark will call abort(3) when a dissector bug is encountered. abort(3) will cause the program to exit abnormally; if you are running 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.

WIRESHARK_EP_VERIFY_POINTERS

This environment variable, if set, causes certain uses of pointers to be audited to ensure they do not point to memory that is deallocated after each packet has been fully dissected. This can be useful to developers writing or auditing code.

WIRESHARK_SE_VERIFY_POINTERS

This environment variable, if set, causes certain uses of pointers to be audited to ensure they do not point to memory that is deallocated after when a capture file is closed. This can be useful to developers writing or auditing code.

WIRESHARK_QUIT_AFTER_CAPTURE

Cause Wireshark to exit after the end of the capture session. This doesn't automatically start a capture; you must still use -k to do that. You must also specify an autostop condition, e.g. -c or -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.

WIRESHARK_ABORT_ON_OUT_OF_MEMORY

This environment variable, if present, causes abort(3) to be called if certain out-of-memory conditions (which normally result in an exception and an explanatory error message) are experienced. This can be useful to developers debugging out-of-memory conditions.
