Tshark windows interface name
Capture Lifecycle with Tshark. The focus is on doing everything in the CLI because that is an interface your scripts and programs can use. Bash features prominently here, with some examples also in python and ruby. Programs such as Termshark and PyShark do novel things by leveraging tshark. You can too by using this guide! For the uninitiated, tshark is the CLI component of Wireshark , and both help you troubleshoot network problems. Now we have a list of network interfaces to capture the computer network bytes.
Capture is to analyze a network message flow. Mostly when needs to verify protocol behavior. The next step is to do an analysis of the captured file. The more accurate the capture, the easier, and fast the analysis will be. The first step is to select the interfaces, where the relevant packets are available. For catapulting on an interface, you can give a numeric value or name.
This option can only be used once on the command line. Example: -z rpc,srt,,3,nfs. Collect statistics for all RTP streams and calculate max. Calculate the RTSP packet distribution. Displayed values are the messages type, send type, and user status. Example: -z scsi,srt,0,ip. Activate a counter for SCTP chunks. This option will activate a counter for SIP messages. Example: -z "sip,stat,ip. When this feature is used TShark will print a report with all the discovered SID and account name mappings.
Only those SIDs where the account name is known will be presented in the table. No data is collected on cancel or oplock break requests, or on unpaired commands.
Only the first response to a given request is used; retransmissions are not included in the calculation.
Calculate the SMPP command distribution. Displayed values are command IDs for both requests and responses, and status for responses.
No data is collected on unpaired messages. Print out the time since the start of the capture and sample count for each IEC Sampled Values packet. Calculate the message distribution of UCP packets. Displayed values are operation types for both operations and results, and whether results are positive or negative, with error codes displayed for negative results. This option may be specified multiple times.
Note that Wireshark currently only displays the first comment of a capture file. List time stamp types supported for the interface. If no time stamp type can be set, no time stamp types are listed. Enable coloring of packets according to standard Wireshark color filters.
On Windows colors are limited to the standard console character attribute colors. Other platforms require a terminal that handles bit "true color" terminal escape sequences. If a key appears multiple times in an object, only write it a single time with as value a json array containing all the separate values. Only works with -T json. When generating the ElasticSearch mapping file, only put the specified protocols in it, to avoid a huge mapping file that can choke some software such as Kibana.
The option takes a list of wanted protocol abbreviations, separated by comma. Export all objects within a protocol into directory destdir.
The available values for protocol can be listed with --export-objects help. The objects are directly saved in the given directory.
Filenames are dependent on the dissector, but typically it is named after the basename of a file. Duplicate files are not overwritten, instead an increasing number is appended before the file extension.
For a complete table of protocol and protocol fields that are filterable in TShark see the wireshark-filter 4 manual page. 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 option -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:. 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:. 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.
As such the Wireshark personal hosts file will not be consulted for capture filter name resolution. If an IPv4 address cannot be translated via name resolution no exact match is found then a partial match is attempted via the subnets file. While the address must be a full IPv4 address, any values beyond the mask length are subsequently ignored. A partially matched name will be printed as "subnet-name. For example, " 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:. The personal ethers file is looked for in the same directory as the personal preferences file.
As such the Wireshark personal ethers file will not be consulted for capture filter name resolution. The format of the file is the same as the ethers files, except that entries of the form:. The mask need not be a multiple of 8. The file has the standard services file syntax; each line contains one service name and one transport identifier separated by white space.
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:.
The personal ipxnets file is looked for in the same directory as the personal preferences file. TShark uses UTF-8 to represent strings internally. In some cases the output might not be valid. For example, a dissector might generate invalid UTF-8 character sequences. Other output will be UTF This environment variable overrides the location of personal configuration files. Available since Wireshark 3. 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. 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. This environment variable causes the various data files to be loaded from a directory other than the standard locations.
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.
If this environment variable is set, TShark will call abort 3 when a dissector bug is encountered. This can be useful to developers attempting to troubleshoot a problem with a protocol dissector. If this environment variable is set, TShark 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. This environment variable controls the verbosity of diagnostic messages to the console.
From less verbose to most verbose levels can be critical , warning , message , info , debug or noisy. Levels above the current level are also active. Levels critical and error are always active. Sets the fatal log level. Fatal log levels cause the program to abort. This level can be set to Error , critical or warning. Error is always fatal and is the default. This environment variable selects which log domains are active. The filter is given as a case-insensitive comma separated list.
If set only the included domains will be enabled. The default domain is always considered to be enabled. Domain filter lists can be preceded by '!
List of domains with debug log level. This sets the level of the provided log domains and takes precedence over the active domains filter. If preceded by '! This is the manual page for TShark 3. TShark is part of the Wireshark distribution. TShark uses the same packet dissection code that Wireshark does, as well as using many other modules from Wireshark ; see the list of authors in the Wireshark man page for a list of authors of that code.
The criterion is of the form key:value , where key is one of:. Run with the given configuration profile. Example: tshark -d. Example: tshark -e frame. Set an option controlling the printing of fields when -T fields is selected.
Set the capture filter expression. Promiscuous mode is the default and allows for snooping ALL traffic, not just the packets destination of your MAC normally these are discarded. Turning it off gives you a view of what the CPU sees instead of the network adapter.
