    p.add_option("-p","--port",dest="port",type="int",default="22",help="port for nagios server",metavar="port")
    (options,args)=p.parse_args()
    result=check_port(options.address,options.port)

if __name__ == "__main__":
    work()


备注:

1、使用socket模块进行类似telnet ip port方式检测;

2、使用OptionParser模块增加可选的选项,默认localhost、22端口;-a跟ip,-p跟端口。
