Python判断telnet通不通的实例
这个跟ping那个差不多,ping的那个脚本就是通过这个改了下,大体一致,不过telnet的不需要判断返回的字符串。快一些
这里具体需要telnet的ip是需要自己向定义好的数组中写的
我这里加了一个定时,是7200秒,也就是2小时
行了,上代码吧:
#!/usr/bin/env python # coding: utf8 import telnetlib import time import codecs import os # telnet host def telnetdo(host, statusFile): status1 = 'telnet success' status2 = 'telnet faild' for ipAdd in host: # get now time nowTime = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time())) try: t = telnetlib.Telnet(ipAdd, port=23, timeout=1) writeToText(nowTime, ipAdd, status1, statusFile) except: writeToText(nowTime, ipAdd, status2, statusFile) # write status information to txt def writeToText(nowTime, ipAdd, status, statusFile): s_text = 'TIME:' + nowTime + '\t' + 'IP:' + ipAdd + '\t' + 'STATUS:' + status + '\r\n' if '0' == judgeFile(statusFile): with open(statusFile, 'a') as f: f.write(s_text) f.close() if '1' == judgeFile(statusFile): with open(statusFile, 'w') as f: f.write(s_text) f.close() # Determine whether statusFile exists # 0: exists # 1: no exists def judgeFile(statusFile): if os.path.exists(statusFile): return '0' else: return '1' if __name__ == "__main__": host = ['192.168.1.254', '192.168.1.100'] # write file statusFile = '/root/telnetStatus.txt' i = 7200 while i: telnetdo(host, statusFile) time.sleep(2) i = i - 1
结果会存在/root下面
以上这篇Python判断telnet通不通的实例就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持【听图阁-专注于Python设计】。
