※ 引述《top90233a (黃金戰士跳恰恰)》之銘言：
: 這次的作業有兩部分
: 第一部分是手寫作業
: 範圍是課本第一章的 2 5 6 10 23(a)(b)
: 一共五題
: 第二部分是 WireShark
: 投影片明天會announce
: 先將題目搶先爆一下
: 1.(10%) Download and install the Wireshark software:
: Go to http://www.wireshark.org/download.html and download and install the
: Wireshark binary for your computer.
: While Wireshark is running, enter a website and have that page displayed in
: your browser. The Ethernet frames containing these HTTP messages will be
: captured by Wireshark. After your browser has displayed the page, stop
: Wireshark packet capture by selecting stop in the Wireshark capture window.
: 2.(10%) How long did it take from when the HTTP GET message was sent until
: the HTTP OK reply was received? (By default, the value of the Time column in
: the packetlisting window is the amount of time, in seconds, since Wireshark
: tracing began. To display the Time field in time-of-day format, select the
: Wireshark View pull down menu, then select Time Display Format, then select
: Time-of-day.)
: 3.(10%)How many HTTP GET request messages were sent by your browser? To which

: 以電子檔繳交到 [email protected]
: 明天助教課堂上會再去講一次作業
: 大家記得要準時交
: 遲交一天扣十分 請大家要記得 感謝
: 助教 王裕博
星期三因為資訊之夜的關係 有一些同學沒有來上課
所以特別再提醒大家一下 下星期要交HW2的手寫作業喔
助教會在上課前去教室收作業 請大家準時繳交
另外還有兩點跟大家說明
1.因為下下星期放假 所以下星期三助教會提前在課堂上講解並宣布HW3
HW3 deadline會在作業宣布後的3~4 weeks 請大家不用太過緊張
不過HW3是socket programming作業 所以請盡量不要缺席
2.HW2_PART2的作業pdf檔 之前手滑把助教的信箱打錯了
現已更正為正確版本: [email protected]
如果之前有下載過作業pdf檔的同學 請務必重新下載
不要寄到錯誤的信箱 感謝大家
