== Getting Wireshark

Wireshark source code and installation packages are available from
https://www.wireshark.org/download.html.

=== 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 https://www.wireshark.org/download.html#thirdparty[download page]
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 About→Folders to find the default
locations on your system.

== Known Problems

Dumpcap might not quit if Wireshark or TShark crashes.
(ws-buglink:1419[])

The BER dissector might infinitely loop.
(ws-buglink:1516[])

Capture filters aren't applied when capturing from named pipes.
(ws-buglink:1814[])

Filtering tshark captures with read filters (-R) no longer works.
(ws-buglink:2234[])

Application crash when changing real-time option.
(ws-buglink:4035[])

Wireshark and TShark will display incorrect delta times in some cases.
(ws-buglink:4985[])

Wireshark should let you work with multiple capture files. (ws-buglink:10488[])
