> a running task, the task stops but the SSH connection is still executing
> scripts on the remote server

> f = open(file,'r')
> s = f.read()
> keyfile = StringIO.StringIO(s)
> mykey = paramiko.RSAKey.from_private_key(keyfile)
> sshcon = paramiko.SSHClient()
> sshcon.set_missing_host_key_policy(paramiko.AutoAddPolicy())
> sshcon.connect(IP, username=username, pkey=mykey)
> stdin, stdout, stderr = sshcon.exec_command(cmd)
> logger.info("stdout ------>"+str(stdout.readlines()))
> logger.info("Error--------->"+str(stderr.readlines()))
> if (stdout.channel.recv_exit_status())!= 0:
