telnet--ftp-java

1、telnet连接步骤.telnet.TelnetClient1 new 一个TelnetClient赋值ip地址，port,超时时间TelnetClient tc=new TelnetClient()；2读取telnet输入流， tc.setDefaultTimeout(10000);tc.connect(1, 23);3用inputstream和outputstream控制输入输出进行交互InputStream in=tc.getInputStream();OutputStream out=tc.getOutputStream();例子TelnetClient tc=new

2、TelnetClient();try tc.setDefaultTimeout(10000);tc.connect(1, 23);InputStream in=tc.getInputStream();OutputStream out=tc.getOutputStream();BufferedReader sin=new BufferedReader(new InputStreamReader(System.in);byte bs=new byte256;int i=0;while(i=in.read(bs)-1)String str=null;if(i=256)str=new

3、String(bs);elsebyte bs2=new bytei;for(int j=0;j-1|str.indexOf(assword:)-1)commond = sin.readLine();out.write(commond+n).getBytes(); out.flush();else/out.write( n).getBytes(); catch (SocketException e) / TODO Auto-generated catch blocke.printStackTrace(); catch (IOException e) / TODO Auto-generated c

4、atch blocke.printStackTrace();ftp连接.ftp.FTPClient;步骤:1建立连接FTPClient ftp = new FTPClient();ftp.connect(1, 21);ftp.login(itcc, itcc)2对目录里的文件进行修改，（上传，删除，重命名等）主要方法Rename(Stirng,String)Connect(String host,int port)Login(username,password)stroeFile系列代码FTPClient ftp = new FTPClient();try ftp.connec

5、t(1, 21);if (!ftp.login(itcc, itcc) System.out.println(Ftp登陆失败);elseftp.setFileType(.ftp.FTP.IMAGE_FILE_TYPE);ftp.storeUniqueFile(1.jpg,new FileInputStream(D:/1.jpg);if(ftp != null & ftp.isConnected()try ftp.disconnect(); catch (IOException e) catch (SocketException e) / TODO Auto-generated

6、catch blocke.printStackTrace(); catch (IOException e) / TODO Auto-generated catch blocke.printStackTrace();Ssh连接 ch.ethz.ssh2.Connection;1建立连接方式：authenticateWithDSA(String, String, String)authenticateWithKeyboardInteractive(String, InteractiveCallback)authenticateWithKeyboardInteractive(String, Stri

7、ng, InteractiveCallback)authenticateWithPassword(String, String)authenticateWithPublicKey(String, char, String)authenticateWithPublicKey(String, File, String)2执行命令得到一个session，通过session,输出命令，并得到返回Session s=conn.openSession();/ch.ethz.ssh2.Sessions.execCommand(command);InputStream stdout = new StreamG

8、obbler(s.getStdout();例子Connection conn = null;BufferedReader sin=new BufferedReader(new InputStreamReader(System.in);conn=new Connection(,22);try conn.connect();conn.authenticateWithPassword(itcc, itcc123);SCPClient ftp = conn.createSCPClient();while(true)Session s=conn.openSession();ByteArr

9、ayOutputStream buffer = new ByteArrayOutputStream();byte bytes = new byte1024;String str=sin.readLine();s.execCommand(str);InputStream stdout = new StreamGobbler(s.getStdout();int count;while (count = stdout.read(bytes) != -1)buffer.write(bytes, 0, count);if(count=1024)System.out.println(new String(bytes);elsebyte bs2=new bytecount;for(int j=0;jcount;j+)bs2j=bytesj;System.out.println(new
