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

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服务器之家。
