python 实现重启路由器
有一些服务，需要动态IP，所以我们用重启路由器的方法实现。人工重启不可选，用定时脚本执行即可。贴代码，每种路由器，提示不一样。需要路由器有telnet功能才行。
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import telnetlib
HOST = "192.168.1.1"
USER = "admin"
PASS = "admin"
router = telnetlib.Telnet(HOST)
router.set_debuglevel(2)
router.read_until("Username:", 12)
router.write(USER + "\r\n")
router.read_until("Password:", 12)
router.write(PASS + "\r\n")
router.read_until("TP-LINK > ", 12)
router.write("enable\r\n")
router.read_until("Enter password: ", 12)
router.write(PASS + "\r\n")
router.read_until("TP-LINK # ", 12)
router.write("sys reboot\r\n")
router.read_until("Continue?", 12)
router.write("Y\r\n")
router.close()
print "Done"
