Inspired by Adam Driscoll and the Sysinternals module I wanted to do something similar so bringing tshark to powershell. Although this module does not at the moment include every single parameter tshark does, I still think it was worth bringing this to powershell to act as another tool for the sysadmins tool-kit you have. I like hanging out in my shell all day so this now allows me to easily use tshark from Powershell .PARAMETER SetInterface This is the same as the -i parameter in tshark but with a more helpful paramter name I think. So this will set the name of the network interface to use for live packet capture. Please note to get a list of YOUR valid network interfaces use the -GetInterface paramter first. .PARAMETER SetCaptureFilter Set the capture filter expression using wireshark syntax, to only filter on dns just simply type dns after this parameter name. Please do not use this if you are un-sure of the syntax, you can always filter the capture file in the wireshark GUI after the capture is complete. .PARAMETER SetDataLinkType Set the data link type to use while capturing packets. The values reported by -GetDataLinkTypes are the values that can be used as the value for this parameter .PARAMETER GetInterfaces Print a list of the interfaces on which TShark 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 -SetInterface option to specify an interface on which to capture. .PARAMETER GetDataLinkTypes List the data link types supported by the interface and exit. The reported link types can be used with the -SetDataLinkTypes parameter .PARAMETER Path Type the full file output path you want the file to go to including the file name and file extension. For example:- -Path C:\Users\MyAccount\MyCapture.pcapng .PARAMETER SetFileType This allows you to see all the possible file extension output types. So you can select a different output to the default pcapng format should you so wish to. Please remember to also specify this in the -Path value the parameter file-type extension you selected .PARAMETER LogPath This will allow you to specify a .txt or .log file to output messages to that appear on the screen during the capture .PARAMETER SetFileCaptureSizeKB This is using the capture ring buffer option from tshark -b and using this to set the file size for the capture you wish to perform. After using this parameter name press TAB to auto-complete the parameter validation pattern .PARAMETER SetFileCaptureDuration This is using the capture ring buffer option from tshark -b this will set the amount of time in seconds that the capture is taken for to a file before going to the next file. After using this parameter name press TAB to auto-complete the parameter validation pattern .PARAMETER SetNumberCaptureFiles This is using the capture ring buffer option from tshark -b allowing you to set the number of rotating capture files you wish to capture. You would use this parameter in with either the -SetFileCaptureSizeKB or -SetFileCaptureDuration to allow you to fix the amount of files to store in the output directory. This will allow you to keep a trace running for days without flooding the hard drive full of data. After using this parameter name press TAB to auto-complete the parameter validation pattern .PARAMETER GetVersion This will display the current version of tshark you are using in the background to perform the task at hand. .PARAMETER OpenFile Allows you to display a capture file within the Powershell window you have open, should you wish to do some quick analysis on the capture .PARAMETER GetStatistics This allows you to choose from a large choice of statistics to display after it has opened the capture file. This is very useful to gain certain insights or to just get the expert statistics .EXAMPLE Start-TShark -Path C:\Zelda.pcapng -SetFileCaptureSizeKB filesize:10240 -SetNumberCaptureFiles files:10 This will output a rotating set of 10 files which will be 10MB in size. Pressing CTRL+C to exit the capture after the desired issue has been captured .EXAMPLE Start-TShark -SetInterface "Wi-Fi" -Path C:\DnsOutput.pcapng -LogPath C:\DnsOutput.txt This will being a capture on the Wi-Fi network interface, outputting to a .pcapng file and also record the output from messages on the Powershell screen to the log file specified in the -LogPath this file capture will continue to capture information until CTRL+C is pressed to stop the capture .EXAMPLE Start-TShark -OpenFile C:\SlowNetwork.pcapng -GetStatistics expert Will open the capture file specified in the -OpenFile parameter, this will also then provide you with the expert analysis information by specifying that value from the pre-defined list of choices on the -GetStatistics parameter .FUNCTIONALITY To use when you have a weird network issue you have been told to fix, allowing you to collect packet information to analyze in Wireshark #> } |
