print "--------Result from? %s -------" % host
for line in cmd_result:
    print line,
s.close()
except paramiko.AuthenticationException:
    print "\033[31;1m%s Authentication Error!\033[0m" % host
except socket.error:
    print "\033[31;1m%s Connection Refused!\033[0m" % host

执行命令:

python batch_ssh.py 10.0.0.8 oldboy 22 SSH_KEY  df

python batch_ssh.py 10.0.0.9 root   33 PASSWORD 123456 df
