  Vendor-supplied Packages

   Most Linux and Unix vendors supply their own Wireshark packages. You
   can usually install or upgrade Wireshark using the package management
   system specific to that platform. A list of third-party packages can
   be found on the download page[23] on the Wireshark web site.

 File Locations

  Wireshark and TShark look in several different locations for
  preference files, plugins, SNMP MIBS, and RADIUS dictionaries. These
  locations vary from platform to platform. You can use "Help › About
  Wireshark › Folders" or `tshark -G folders` to find the default
  locations on your system.
