Edit: this menu allows to copy and find specific content, to mark and ignore packets, manage timing options and packet comments. Through this menu you can also setup different configuration profiles and edit preferences such as visual preferences, mac and IP addresses resolutions and more. View : this menu allows to configure different visual options such as menus, toolbars, zoom, expand and collapse among other estetic options. Capture: from this menu you can launch Wireshark and configure options related to the capture of packages such as filters, name resolutions, interfaces and output options.

Analyze: from this menu you can enable and disable protocol dissectors, decode some packets and manage display filters. This is essentially the same data reported in Wireshark's About Folders tab. Fields are tab-delimited. The first field, 'V', 'R' or 'T', indicates the type of record. Network interface names should match one of the names listed in " tshark -D " described above ; a number, as reported by " tshark -D ", can also be used.

If you're using UNIX, " netstat -i ", " ifconfig -a " or " ip link " might also work to list interface names, although not all versions of UNIX support the -a option to ifconfig. If no interface is specified, TShark 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, TShark 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. Data read from pipes must be in standard pcapng or pcap format.

Pcapng data must have the same endianness as the capturing host. When capturing from multiple interfaces, the capture file will be saved in pcapng format. 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.

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. This may be useful when piping the output of TShark to another program, as it means that the program to which the output is piped will see the dissected data for a packet as soon as TShark sees the packet and generates that output, rather than seeing it only when the standard output buffer containing that data fills up.

N to enable using external resolvers e. 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. When reading a capture file, or when capturing and not saving to a file, don't print packet information; this is useful if you're using a -z option to calculate statistics and don't want the packet information printed, just the statistics.

This outputs less than the -q option, so the interface name and total packet count and the end of a capture are not sent to stderr. Note that forward-looking fields such as 'response in frame ' cannot be used with this filter, since they will not have been calculate when this filter is applied.

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. It can be used with -j or -J to specify which protocols to include or with -x to include raw hex-encoded packet data. If -P is specified it will print the packet summary only, with both -P and -V it will print the packet summary and packet details.

If neither -P or -V are used it will print the packet details only. Example of usage to import data into Elasticsearch:. This file can be auto-generated with the command "tshark -G elastic-mapping". Since the mapping file can be huge, protocols can be selected by using the option --elastic-mapping-filter:. For example,.

It can be used with -j or -J to specify which protocols to include or with -x option to include raw hex-encoded packet data.

Example of usage:. It can be used with -j or -J to specify which protocols to include. This information is equivalent to the packet details printed with the -V option. Using the --color option will add color attributes to pdml output. These attributes are nonstandard.

This information is equivalent to the information shown in the one-line summary printed by default. This is the default. Enter an empty tap name "" or a tap name of? NOTE: -w provides raw packet data, not text. If you want text output you need to redirect stdout e. Future versions of Tshark may automatically change the capture format to pcapng as needed.

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.

Use this instead of -R for filtering using single-pass analysis. If doing two-pass analysis see -2 then only packets matching the read filter if there is one will be checked against this filter. Note that the -z proto option is different - it doesn't cause statistics to be gathered and printed when the capture is complete, it modifies the regular packet summary output to include the values of fields specified with the option.

Therefore you must not use the -q option, as that option would suppress the printing of the regular packet summary output, and must also not use the -V option, as that would cause packet detail information rather than packet summary information to be printed. If the optional filter is specified, only those packets that match the filter will be used in the calculations. The table is sorted according to the total number of frames. Example: -z dcerpc,srt,abcd-efac,1. If the optional filter is provided, the stats will only be calculated on those calls that match that filter.

Example: -z diameter,avp extract default field set from diameter messages. Example: -z diameter,avp, extract default field set from diameter DWR messages. Example: -z diameter,avp, extract default field set from diameter CC messages. Several fields with same name within one diameter message are supported, e.

Subscription-Id-Data or diameter. Note: tshark -q option is recommended to suppress default tshark output. Example: -z expert,sip will show expert items of all severity for frames that match the sip protocol.

Example: -z "expert,note,tcp" will only collect expert items for frames that include the tcp protocol, with a severity of note or higher. Since the output in ascii or ebcdic mode may contain newlines, the length of each section of output plus a newline precedes each section of output.

TLS streams are selected with the stream index. For example:. Example: -z "follow,tcp,hex,1" will display the contents of the second TCP stream the first is stream 0 in "hex" format. Example: -z "follow,tcp,ascii, Example: use -z "h,counter,ip.

Example: -z "h,srt,ip. Addresses are collected from a number of sources, including standard "hosts" files and captured traffic. Example: -z icmp,srt,ip. Example: -z icmpv6,srt,ipv6. If no filter is specified the statistics will be calculated for all packets.

If one or more filters are specified statistics will be calculated for all filters and presented with one column of statistics for each filter. Example: -z io,stat,1,ip.

Example: -z "io,stat,0. The examples above all use the standard syntax for generating statistics which only calculates the number of packets and bytes in each interval.

So: -z io,stat,0. Use -z io,stat,0. Also be aware that a field can exist multiple times inside the same packet and will then be counted multiple times in those packets. NOTE: A second important thing to note is that the system setting for decimal separator must be set to ". If it is set to "," the statistics will not be displayed per filter. COUNT field filter - Calculates the number of times that the field name not its value appears per interval in the filtered packet list.

Reports the total number of bytes that were transmitted bidirectionally in all the packets within a 10 millisecond interval. The specified field must be a named integer, float, double or relative time field. For relative time fields, the output is presented in seconds with six decimal digits of precision rounded to the nearest microsecond.

The specified field must be a relative time field that represents a response time. For example smb. For each interval the Queue-Depth for the specified protocol is calculated. A value of 1. The filter field is optional but if included it must be prepended with '' ''. The following command displays five columns: the total number of frames and bytes transferred bidirectionally using a single comma, the same two stats using the FRAMES and BYTES subcommands, the total number of frames containing at least one SMB Read response, and the total number of bytes transmitted to the client unidirectionally at IP address If the optional filter is provided, the stats will only be calculated for those frames that match that filter.

Example: -z "mac-lte,stat,mac-lte. Example: -z "megaco,rtd,ip. Example: -z "mgcp,rtd,ip. If not, TShark will not be able to extract its value.

For a simple example to add the "nfs. To put "nfs. Example: -z "rlc-lte,stat,rlc-lte. Example: -z rpc,srt,,3,nfs. Example: -z scsi,srt,0,ip. Example: -z "sip,stat,ip. Only those commands that are seen in the capture will have its stats displayed.

In other words, tshark aliases to tshark -i 1. You may need to use sudo depending on your installation. Default interfaces on installs of macos, windows, linux, and freebsd are shown below.

Entering the tshark command should immediately start capturing packets on the default interface. If you do not see packets, check out Choosing an Interface. Setting up your environment should be done once and done well. There are a couple Additional work is usually necessary to make sure all utilities are on the path. For example, on Linux for 3.
