客戶通過Socket(InetAddress,port)建立與服務(wù)器的連接。服務(wù)器與客戶都通過構(gòu)造BufferedReader,PrintWriter來建立輸入輸出流，然后雙方通過該輸入輸出流來相互傳遞信息，一旦收到客戶方的連接請求，服務(wù)器accept()方法返回一個新建的Socket對象。客戶端然后向服務(wù)器發(fā)送消息，比如注冊，登錄，查找好友等，服務(wù)器收到來自客戶的請求后，針對不同的消息處理請求, 雖然UDP不可靠但是對于icq可靠性并不太重要，而且UDP快速，所以客戶間發(fā)送信息通過UDP。用戶登錄時通過類DatagramPacket和DatagramSocket創(chuàng)建UDP包括其本地接受端口以及發(fā)送端口，默認端口為5000和5001，通過取得的好友的IP地址來向好友發(fā)送消息（send(DatagramPacket)和接受消息(receive(DatagramPacket))。當用戶通過UDP收到消息后，可以通過DatagramPacket的方法InetAddress getAddress()得到對方的ip地址，通過對好友列表比較以判斷是誰并提示用戶收到某某的消息，然后用戶選擇該用戶查看消息，如果好友列表沒有該人就顯示收到陌生人的消息。用戶可以按陌生人按鈕查看消息。

編寫漏洞掃描器探查遠程服務(wù)器上可能存在的具有安全隱患的文件是否存在，它的socket建立過程和上面 的端口掃描器是相同的，所不同的是漏洞掃描器通常使用80端口，然后對這個端口發(fā)送一個GET文件的請求，服務(wù)器接收到請求會返回文件內(nèi)容，如果文件不存 在則返回一個錯誤提示，通過接收返回內(nèi)容可以判斷文件是否存在。發(fā)送和接收數(shù)據(jù)需要使用函數(shù)send()和recv()，另外對流中存在的字符串進行判斷 需要使用函數(shù)strstr()，這除了需要具備socket函數(shù)庫的知識以外，還需要一些有關(guān)string函數(shù)庫的知識。

抓包代碼 那段代碼，是我自己寫的。這兩個是東西是完成send和RECV兩個地方，所以返回的地址不一樣。這才搞出來那么多代碼來

加密算法實現(xiàn) Pegwit is a program for performing public key file encryption and authentication. Encryption means that pegwit allows you to keep the information in files you send by email (or other means) confidential. Eavesdroppers will not be able to read the email. Authentication allows you to check that a file has not been tampered with (changed) since it was signed.

[解決方法] 對上述程序改動如下: 發(fā)送端: MMM sendBag ZeroMemory(&sendBag,sizeof(sendBag)) ............. int send = 0 while(send<sizeof(MMM)) { int nCharsend=send(m_hSocket,(char*)(&sendBag+send),sizeof(MMM)-send,0) send+=nCharsend } 接收端: MMM RecvBag ZeroMemory(&RecvBag,sizeof(RecvBag)) recv寫法同上while... 此方法適合傳送結(jié)構(gòu)體的實現(xiàn). 趕快試試看.

CAN1.c and CAN2.c are a simple example of configuring a CAN network to transmit and receive data on a CAN network, and how to move information to and from CAN RAM message objects. Each C8051F040-TB CAN node is configured to send a message when it s P3.7 button is depressed/released, with a 0x11 to indicate the button is pushed, and 0x00 when released. Each node also has a message object configured to receive messages. The C8051 tests the received data and will turn on/off the target board s LED. When one target is loaded with CAN2.c and the other is loaded with CAN1.c, one target board s push-button will control the other target board s LED, establishing a simple control link via the CAN bus and can be observed directly on the target boards.
