【正文】 這樣，宿主電腦上網(wǎng)后，虛擬機也就可以通過宿主計算機共享上網(wǎng)了三、實驗結(jié)果。第三步:在宿主電腦“網(wǎng)絡(luò)和撥號連接”窗口中，右擊 ADSL 虛擬撥號連接，選擇“屬性”命令，在“共享”標(biāo)簽頁內(nèi)選中“啟用此連接的 Internet 連接共享”，然后根據(jù)虛擬機網(wǎng)卡的工作方式選擇一個網(wǎng)絡(luò)連接(見圖 6)，具體對應(yīng)如下:網(wǎng)橋—本地連接NAT—VMware Network Adapter VMnet8 只是主機—VMware Network Adapter Vmnet1第四步:宿主電腦啟用網(wǎng)絡(luò)連接后，相應(yīng)網(wǎng)絡(luò)連接的 IP 地址被自動設(shè)置為 。 這一步是最后一步了，虛擬磁盤即將被創(chuàng)建，advanced 里可以更改虛擬磁盤的接口是SCSI 或是 IDE4 虛擬機共享上網(wǎng)第一步:點擊 VMware 菜單“虛擬→設(shè)置”，再點選網(wǎng)卡 NIC 并設(shè)置它的屬性，可在“網(wǎng)橋”、“NAT”、“僅是主機”中任選一項，但一定要記住所選的項目。第二項允許虛擬機無限使用磁盤空間，但需要真實磁盤足夠大。 設(shè)置虛擬機磁盤容量。 當(dāng)?shù)谝淮谓⑻摂M機時，請選擇第一項，第二項適用于建立第二個或更多虛擬機，即使用已經(jīng)建立好的虛擬機磁盤，這樣可以減少虛擬機占用的真實磁盤空間。二、實驗內(nèi)容和步驟1 可以到官方網(wǎng)站下載 虛擬機安裝軟件，直接點 next 下一步直接安裝完成即可2 添加設(shè)備，點擊 add，添加過程就像剛開始配置安裝虛擬機過程一樣。}()。catch (Exception ex) {} }else {(message)。if ((()).equals (endMessage)){message = ()。boolean done = false。(())。MyStreamSocket myDataSocket = new MyStreamSocketwhile (true) { ServerSocket myConnectionSocket = new ServerSocket(serverPort)。try { serverPort = (args[0])。String message。 int serverPort = 7。public static void main(String[] args) {static f?inal String endMessage = .。import .*。(endMessage)。public void done() throws SocketException, IOException{echo = ()。String echo = 。public String getEcho( String message) throws SocketException, IOException{ = new MyStreamSocket(, )。 = (hostName)。throws SocketException,UnknownHostException, IOException {EchoClientHelper2(String hostName,String portNum)private int serverPort。private InetAddress serverHost。private MyStreamSocket mySocket。static f?inal String endMessage = .。import .*。} catch (Exception ex) {} }}else {}if ((()).equals (endMessage)){+ from the server, or a single period to quit.)。portNum = 7。if (() == 0)String portNum = ()。(What is the port number of the server host?)。hostName = localhost。if (() == 0)String hostName = ()。What is the name of the server host?)。(Wele to the Echo client.\n +BufferedReader br = new BufferedReader(is)。public class EchoClient2 { return message。 ()。 output = new PrintWriter(new OutputStreamWriter(outStream))。 input = new BufferedReader(new InputStreamReader(inStream))。 setStreams()。 setStreams()。 private PrintWriter output。public class MyStreamSocket extends Socket { private Socket socket。共有的：import .*。}return 。public InetAddress getAddress() {} = port。 = message。public void putVal(String message, InetAddress addr, int port) {private int senderPort。private InetAddress senderAddress。private String message。} } import .*。return returnVal。())。(new String(receiveBuffer), (),DatagramMessage returnVal = new DatagramMessage()。(datagram)。DatagramPacket datagram = new DatagramPacket(receiveBuffer, MAX_LEN)。byte[ ] receiveBuffer = new byte[MAX_LEN]。} return message。String message = new String(receiveBuffer)。(datagram)。DatagramPacket datagram = new DatagramPacket(receiveBuffer, MAX_LEN)。byte[ ] receiveBuffer = new byte[MAX_LEN]。} (datagram)。new DatagramPacket(sendBuffer, , receiverHost, receiverPort)。DatagramPacket datagram =throws IOException { }super(portNo)。import .*。} ()。catch (Exception ex) {} (), message)。(message received: + message)。(Request received)。while (true) {(Echo server ready.)。MyServerDatagramSocket mySocket = new MyServerDatagramSocket(serverPort)。if ( == 1 ) public class EchoServer1 {throws IOException {public String receiveMessage() byte[ ] sendBuffer = ()。public void sendMessage(InetAddress receiverHost, int receiverPort, String message)MyClientDatagramSocket(int portNo) throws SocketException{MyClientDatagramSocket() throws SocketException{public class MyClientDatagramSocket extends DatagramSocket {static final int MAX_LEN = 100。}import .*。} return echo。 ( serverHost, serverPort, message)。} = new MyClientDatagramSocket()。 = (portNum)。 = (hostName)。public class EchoClientHelper1 { import .*。} catch (Exception ex) {} } }else {}if ((()).equals (endMessage)){+ or a single peroid to quit.)。(Enter a line to receive an echo back from the server, while (!done) {String message, echo。boolean done = false。EchoClientHelper1 helper = new EchoClientHelper1(hostName, portNum)。try {InputStreamReader is = new InputStreamReader()。public static void main(String[] args) {static final String endMessage = .。} } 3. 用數(shù)據(jù)包 socket 實現(xiàn)的 echo 應(yīng)用程序包的構(gòu)架，列明各程序之間的關(guān)系；客戶端：import .*。} ()。(())。(timestamp sent: + ())。Date timestamp = new Date ()。(A client has made connection.)。(())。MyStreamSocket myDataSocket = new MyStreamSocket(Waiting for a connection.)。while (true) {(Daytime server ready.)。ServerSocket myConnectionSo
