剛架好Web Server
想知道能否正常連線或是否被Firewall擋住
除了開瀏覽器外
還可以用TELNET來檢測


TELNET www.test.com.tw 80
GET /index.html HTTP/1.0
( enter按兩次 )

如果沒被擋或架設成功會出現類似如下： 

HTTP/1.1 200 OK
Date: Wed, 11 Sep 2013 06:33:08 GMT
Server: Apache/2.2.21 (FreeBSD) mod_ssl/2.2.21 OpenSSL/0.9.8q DAV/2
Last-Modified: Wed, 11 Sep 2013 06:32:53 GMT
ETag: "9da84-4-4e615ca810f40"
Accept-Ranges: bytes
Content-Length: 4
Connection: close
Content-Type: text/plain

321                   <---- index.html的檔案內容
Connection closed by foreign host.

HTTP/1.1 200 OK 表示連線成功，也連到目標物index.html

 

不過須注意的是，如果中間有Proxy的話
會出現下面訊息

 

HTTP/1.0 503 Service Unavailable
