I use ssh which in turn uses paramiko

  import os
  import ssh
  for i in xrange(len(tasks)):
                pid = os.fork()
                if pid == 0:
                    # if child process
                    s = ssh.Connection(host = server, log =
False)
                    s.execute(cmd)
                    s.close()
                    os._exit(0)
                time.sleep(1)

  os.waitpid(pid, 0)
