網路卡頓找不到原因？Wireshark 抓封包看真相

What's new in this version:

WHAT'S NEW:
- Wireshark 2.0 features a completely new user interface which should provide a smoother, faster user experience. The new interface should be familiar to current users of Wireshark but provide a faster workflow for many tasks
- The Windows installer provides the option of installing either the new interface (“Wirehsark”) or the old interface (“Wireshark Legacy”). Both are installed by default. Note that the legacy interface will be removed in Wireshark 2.2
- The OS X installer only provides the new interface. If you need the old interface you can install it via Homebrew or MacPorts
- Wireshark’s Debian- and RPM-based package definitions provide the new interface in the “wireshark-qt” package and the old interface in the “wireshark-gtk” package. It is hoped that downstream distributions will follow this convention

BTSNOOP, PCAP, and PCAPNG

Major API Changes:

The libwireshark API has undergone some major changes:
- The emem framework (including all ep_ and se_ memory allocation routines) has been completely removed in favour of wmem which is now fully mature
- The (long-since-broken) Python bindings support has been removed. If you want to write dissectors in something other than C, use Lua
- Plugins can now create GUI menu items
- Heuristic dissectors can now be globally enabled/disabled so heur_dissector_add() has a few more parameters to make that possible
- proto_tree_add_text has been removed
- tvb_length() has been removed in favor of tvb_reported_length() and tvb_captured_length()
- The API for ONC RPC-based dissectors has changed significantly: the procedure dissectors no longer take an offset, void-argument procedures now need to be declared with a function (use dissect_rpc_void()), and rpc_init_prog() now handles procedure registration too (it takes additional arguments to handle this; rpc_init_proc_table() was removed)
