網路慢到想抓狂?Wireshark 抓封包找元兇
網路突然變慢、連線一直斷、某個網站就是開不起來,你重開路由器、換網路線、甚至重灌電腦,問題還是沒解決。你想知道封包到底在搞什麼鬼,但打開命令提示字元只看到一片黑,不知道從哪裡下手。這種時候,你需要的是把網路流量攤開來看的工具。
一般人遇到網路問題,能做的就是重開機、換線、打客服,這些動作只能碰運氣。要真正找出問題,得看封包內容——誰在跟誰說話、傳了什麼、哪裡卡住。這類工具就是讓你把網路流量攤開來看,但前提是你得知道怎麼看。它不會自動告訴你答案,而是給你線索,讓你自己判斷。
01Wireshark 32-bit 能抓無線網路的封包嗎?
可以,但需要相容的無線網卡和驅動程式。它支援 IEEE 802.11 無線網路的即時封包擷取,不過不是每張網卡都能進入監聽模式,有些網卡會漏掉部分封包。建議先確認你的網卡型號是否在支援清單內,再決定要不要用它來抓無線流量。
02它能看加密的封包內容嗎?
它能擷取加密流量,但無法直接解密,除非你手上握有加密金鑰。例如 HTTPS 流量,如果沒有伺服器的私鑰,看到的只會是亂碼。它支援 IPsec、SSL/TLS、WPA/WPA2 等協定的解密,但前提是金鑰要能取得,這在實務上通常只有管理自己伺服器的人才辦得到。
03網路變慢可以用它找出原因嗎?
可以,它常被用來排查連線問題、效能瓶頸和應用程式通訊錯誤。做法是抓一段時間的封包,用顯示過濾器篩出特定 IP 或通訊埠,觀察延遲、重傳和封包遺失的狀況。不過要能解讀這些數據,你得先懂 TCP/IP 的基本概念,否則只會看到一堆看不懂的數字。
04它能拿來檢查有沒有被入侵嗎?
可以,資安人員常用它分析網路流量、偵測異常行為和調查資安事件。例如看到來路不明的連線、大量異常的封包傳輸,都可以當作線索。但它不是自動掃描工具,不會主動告訴你「這裡有問題」,你得自己知道正常流量長什麼樣子,才能分辨出異常。
05它能讀取其他軟體抓的封包檔嗎?
可以,它支援多種擷取檔案格式,包括 tcpdump 的 libpcap、Pcap NG、Microsoft Network Monitor、Sniffer 等。所以就算你原本用別的軟體抓封包,也可以把檔案丟進來分析。它也支援 gzip 壓縮的檔案,可以即時解壓縮,不用先手動解開。
06新手學得會嗎?
學習曲線比較陡,因為它需要基本的網路概念,像是 TCP/IP、DNS、HTTP 這些協定至少要聽過。介面是英文的,三個窗格分別顯示封包清單、協定樹和原始資料,第一次打開會覺得資訊量很大。建議先從官方教學文件或 YouTube 上的入門影片開始,照著抓幾次封包,慢慢就會上手。
07公司網管用它夠用嗎?
它是網路專業人士常用的工具,全球很多網管和工程師都在用。功能上涵蓋深度協定檢查、即時擷取、離線分析、VoIP 分析、多種過濾器,對日常維運和故障排除來說很夠用。不過它是免費開源軟體,沒有原廠技術支援,遇到問題得靠自己查文件或上社群問。
08學校教學適合用嗎?
適合,它本來就常被用在網路課程和教材裡,因為免費、跨平台、支援的協定又多,學生可以自己裝來練習。不過教學時需要有人帶,否則學生光看介面就會卡住。它也有 TShark 命令列工具,可以寫成腳本讓學生跑自動化分析,但這需要額外花時間教。
0932位元版還值得裝嗎?
32位元版已經長期沒有新版本,官方把資源都放在 64位元版上。如果你的電腦是 64位元系統,直接裝 64位元版就好,功能更完整。只有當你還在用很舊的 32位元 Windows 系統,才需要考慮 32位元版,但也要有心理準備它不會再更新。
10電腦很舊跑得動嗎?
它本身不算輕量,抓封包和解析大量資料時會吃記憶體和 CPU。官方只說系統需求依平台和使用情境而異,沒有給具體數字。如果你的電腦記憶體很少,抓大流量封包可能會卡頓或當機。建議先抓一小段時間試試,確認跑得動再擴大使用。
11想解 HTTPS 流量夠用嗎?
它支援 SSL/TLS 解密,但前提是你有伺服器的私鑰,而且金鑰交換方式要符合它的限制。對一般使用者來說,要拿到自己瀏覽的網站私鑰幾乎不可能,所以實務上只能解自己伺服器的流量。如果你只是想看自己電腦的 HTTPS 內容,它幫不上忙。
12有更簡單的替代工具嗎?
有,例如 SmartSniff 和 Acrylic Wi-Fi Home 都是功能相近的選擇,但評分人數都比它少,代表使用者的回饋樣本比較有限。SmartSniff 介面比較簡單,適合只想快速看封包的人;Acrylic Wi-Fi Home 則偏無線網路分析。不過這些工具的功能深度都不如它,看你需要多細的分析。

這一版改了什麼
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

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)
