觀察HTTP response status code(HTTP回應狀態代碼)
瀏覽網頁時，可以觀察該網頁或網頁內元件(例如嵌入圖檔或聲音)的HTTP response status code(HTTP回應狀態代碼)[1]，例如404代表沒有該檔案。
- Mozilla Firefox Firefox 內建的工具 -> 網頁開發者 -> 網頁主控台。快速鍵: Ctrl+Shift+k。
- filter: available
- example as follows:
[23:14:47.836] GET https://www.google.com/ [HTTP/1.1 200 OK 10763ms] [23:14:59.707] GET https://www.google.com/ig/cp/get?hl=zh-TW&gl=&authuser=0&bundleJs=0 [HTTP/1.1 304 Not Modified 1593ms]
- Firebug for Firefox : 切換到「網路」標籤。快速鍵: F12
- Google Chrome 內建的工具 -> 開發人員工具 -> 切換到「network」標籤。快速鍵: Ctrl+Shift+i

反查IP或網域
無法網路連線
- ping local IP
- ping Gateway
- check DNS...
- (optional) ping the IP of external website (有些機器會關閉ICMP ECHO，讓我們無法Ping到它)
distinguish which section met trouble
無法連線到網路的測試步驟
- 檢查網站服務 for Linux
- /etc/init.d/httpd status
- /etc/init.d/mysqld status
- 檢查本機端網站網頁是否能讀取
- lynx 127.0.0.1
- 檢查網站伺服器log
- 從瀏覽器直接瀏覽網站網址
網路連線發生不穩
如何看出哪一段線路慢了？
- Windows: 開始 -> 執行 -> 輸入cmd (進入"命令提示字元")
- (會顯示C:\某資料夾>)
- 請在閃爍游標處輸入 tracert web.domain.com (web.domain.com 改成想檢查的網站網址)
- 就可以看出是哪一段慢了，大家先作這個動作會有助於解決問題及增加回覆的速度喔
或者
- 請在閃爍游標處輸入 tracert web.domain.com > c:\result.txt
- 當出現第二次C:\某資料夾> (如果網路連線不穩定, 會花費相當多時間)
- 代表已經將連線過程紀錄成功在 c:\result.txt
- 請將這個文字檔寄給合適的網路管理員
類似工具
GeoIP服務
- Geo IP Tool (含地圖)
- My IP Address Lookup / IP Locator / Trace IP / What is my ip (含地圖)
- IP Address Lookup (IPv4 & IPv6)
Blog
- Is My Blog Working? "Enter your blog address above to check your server status, RSS feed, markup, security, and performance." (圖例)
伺服器主機資訊
- Netcraft可查詢伺服器主機的OS、IP及上線時間(uptime)等資訊。 ex: Site report for www.netcraft.com
- Bookmarklet for checking the information of server which you browsed
javascript:location%20=%20'http://uptime.netcraft.com/up/graph?site='+escape(location);%20void%200
- Check HTTP compression: (1) Compression status (gzip), (2) Web server type ex: Compression Check of google.com [Last visited: 2012-03-09]
