如何通过python脚本检查NTP服务器是否在Linux计算机上运行

Question

I need to get IP address of a machine and check if NTP server is running on that. In addition, if it is not running, just start it. I checked several posts and non of them worked for me.

You can use fabric for this. It's great! Here's a quick and dirty way:

from fabric.api import run

def restart_ntp_if_not_running():
    run('if [[ $(netstat -p tcp -n | grep [your ip].123 | grep ESTABLISHED) ]]; then true; else [your command to restart here]; fi;')

The execute this like:

fab -H [host name] restart_ntp_if_not_running
